NUCLEAR REGULATORY COMMISSION

[Docket Nos. 50-206, 50-361, 50-362, and 72-41; NRC-2015-0093]


Southern California Edison Company; San Onofre Nuclear Generating 
Station, Units 1, 2, and 3, and Independent Spent Fuel Storage 
Installation

AGENCY: Nuclear Regulatory Commission.

ACTION: Exemption; issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is granting 
exemptions in response to a request from Southern California Edison 
Company (SCE or the licensee) regarding certain emergency planning (EP) 
requirements. The exemptions will eliminate the requirements to 
maintain formal offsite radiological emergency plans and reduce the 
scope of the onsite EP activities at the San Onofre Nuclear Generating 
Station (SONGS), Units 1, 2, and 3, and the Independent Spent Fuel 
Storage Installation (ISFSI), based on the reduced risks of accidents 
that could result in an offsite radiological release at the 
decommissioning nuclear power reactors. Provisions would still exist 
for offsite agencies to take protective actions, using a comprehensive 
emergency management plan to protect public health and safety, if 
protective actions were needed in the event of a very unlikely accident 
that could challenge the safe storage of spent fuel.

SUPPLEMENTARY INFORMATION:

I. Background

    The SONGS Units 1, 2, and 3, are decommissioning power reactors 
located in San Diego County, California. The licensee, SCE, is the 
holder of SONGS Facility Operating License Nos. DPR-13, NPF-10, and 
NPF-15. The licenses provide, among other things, that the facility is 
subject to all rules, regulations, and orders of the NRC now or 
hereafter in effect.
    SONGS Unit 1 was permanently shut down in 1993. On June 12, 2013 
(ADAMS Accession No. ML131640201), the licensee provided the 
certifications that SONGS Units 2 and 3, had permanently ceased power 
operations. On June 28 (ADAMS Accession No. ML13183A391), and July 22, 
2013 (ADAMS Accession No. ML13204A304), the licensee provided 
certifications that all fuel had been permanently removed from the 
SONGS Units 3 and 2, reactors, respectively. As a permanently shutdown 
and defueled facility, and pursuant to section 50.82(a)(2) of Title 10 
of the Code of Federal Regulations (10 CFR), SCE is no longer 
authorized to operate the reactors or emplace fuel into the reactor 
vessels, but is still authorized to possess and store irradiated 
nuclear fuel. Irradiated fuel is currently stored onsite at SONGS in 
spent fuel pools (SFPs) and in the ISFSI dry casks.
    During normal power reactor operations, the forced flow of water 
through the reactor coolant system (RCS) removes heat generated by the 
reactor. The RCS, operating at high temperatures and pressures, 
transfers this heat through the steam generator tubes converting non-
radioactive feedwater to steam, which then flows to the main turbine 
generator to produce electricity. Many of the accident scenarios 
postulated in the updated safety analysis reports (USARs) for operating 
power reactors involve failures or malfunctions of systems that could 
affect the fuel in the reactor core, which in the most severe 
postulated accidents, would involve the release of some fission 
products into the environment. With the permanent cessation of reactor 
operations at SONGS and the permanent removal of the fuel from the 
reactor vessels, such accidents are no longer possible. The reactors, 
RCS, and supporting systems are no longer in operation and have no 
function related to the storage of the irradiated fuel. Therefore, 
postulated accidents involving failure or malfunction of the reactors, 
RCS, or supporting systems are no longer applicable.
    The EP requirements of 10 CFR 50.47, ``Emergency plans,'' and 
appendix E to 10 CFR part 50, ``Emergency Planning and Preparedness for 
Production and Utilization Facilities,'' continue to apply to nuclear 
power reactors that have permanently ceased operation and have removed 
all fuel from the reactor vessel. There are no explicit regulatory 
provisions distinguishing EP requirements for a power reactor that is 
permanently shut down and defueled from those for a reactor that is 
authorized to operate. To reduce or eliminate EP requirements that are 
no longer necessary due to the decommissioning status of the facility, 
SCE must obtain exemptions from those EP regulations. Only then can SCE 
modify the SONGS emergency plan to reflect the reduced risk associated 
with the permanently shutdown and defueled condition of SONGS .

II. Request/Action

    By letter dated March 31, 2014 (ADAMS Accession No. ML14092A332), 
``Emergency Planning Exemption Request,'' SCE requested exemptions from 
certain EP requirements of 10 CFR part 50 for SONGS. More specifically, 
SCE requested exemptions from certain planning standards in 10 CFR 
50.47(b) regarding onsite and offsite radiological emergency plans for 
nuclear power reactors; from certain requirements in 10 CFR 50.47(c)(2) 
that require establishment of plume exposure and ingestion pathway 
emergency planning zones for nuclear power reactors; and from certain 
requirements in 10 CFR part 50, appendix E, Section IV, which 
establishes the elements that make up the content of emergency plans. 
In letters dated September 9, October 2, October 7, October 27, 
November 3, and December 15, 2014 (ADAMS Accession Nos. ML14258A003, 
ML14280A265, ML14287A228, ML14303A257, ML14309A195, and ML14351A078, 
respectively), SCE provided responses to the NRC staff's requests for 
additional information (RAI) concerning the proposed exemptions. In 
addition, SCE submitted a letter dated October 6, 2014, which contains 
security-related information, and is therefore withheld from public 
disclosure. The December 15, 2014, letter is a redacted, publicly-
available version of this letter.
    The information provided by SCE included justifications for each 
exemption requested. The exemptions requested by SCE would eliminate 
the requirements to maintain formal offsite radiological emergency 
plans, reviewed by the Federal Emergency Management Agency (FEMA) under 
the requirements of 44 CFR part 350, and reduce the scope of onsite EP 
activities. The SCE stated that application of all of the standards and 
requirements in 10 CFR 50.47(b), 10 CFR 50.47(c), and 10 CFR part 50, 
appendix E is not needed for adequate emergency response capability, 
based on the substantially lower onsite and offsite radiological 
consequences of accidents still possible at the permanently shutdown 
and defueled facility as compared to an operating facility. If offsite 
protective actions were needed for a very unlikely accident that could 
challenge the safe storage of spent fuel at SONGS, provisions exist for 
offsite agencies to take protective actions using a comprehensive 
emergency management plan (CEMP) under the National Preparedness System 
to protect the health and safety of the public. A CEMP in this context, 
also referred to as an emergency operations plan (EOP), is addressed in 
FEMA's Comprehensive Preparedness Guide 101, ``Developing and 
Maintaining Emergency Operations Plans.'' Comprehensive Preparedness 
Guide 101 is the foundation for State, territorial, Tribal, and local 
EP in the United States. It promotes a common understanding of the 
fundamentals of

[[Page 33560]]

risk-informed planning and decision-making and helps planners at all 
levels of government in their efforts to develop and maintain viable, 
all-hazards, all-threats emergency plans. An EOP is flexible enough for 
use in all emergencies. It describes how people and property will be 
protected; details who is responsible for carrying out specific 
actions; identifies the personnel, equipment, facilities, supplies and 
other resources available; and outlines how all actions will be 
coordinated. A CEMP is often referred to as a synonym for ``all-hazards 
planning.''

III. Discussion

    In accordance with 10 CFR 50.12, ``Specific exemptions,'' the 
Commission may, upon application by any interested person or upon its 
own initiative, grant exemptions from the requirements of 10 CFR part 
50 when: (1) The exemptions are authorized by law, will not present an 
undue risk to public health or safety, and are consistent with the 
common defense and security; and (2) any of the special circumstances 
listed in 10 CFR 50.12(a)(2) are present. These special circumstances 
include, among other things, that the application of the regulation in 
the particular circumstances would not serve the underlying purpose of 
the rule or is not necessary to achieve the underlying purpose of the 
rule.
    As noted previously, the current EP regulations contained in 10 CFR 
50.47(b) and appendix E to 10 CFR part 50 apply to both operating and 
shutdown power reactors. The NRC has consistently acknowledged that the 
risk of an offsite radiological release at a power reactor that has 
permanently ceased operations and removed fuel from the reactor vessel 
is significantly lower, and the types of possible accidents are 
significantly fewer, than at an operating power reactor. However, 
current EP regulations do not recognize that once a power reactor 
permanently ceases operation, the risk of a large radiological release 
from a credible emergency accident scenario is reduced. The reduced 
risk is largely the result of the low frequency of credible events that 
could challenge the SFP structure, and the reduced decay heat and 
reduced short-lived radionuclide inventory due to decay. The NRC's 
NUREG/CR-6451, ``A Safety and Regulatory Assessment of Generic BWR and 
PWR Permanently Shutdown Nuclear Power Plants,'' dated August 31, 1997 
(ADAMS Accession No. ML082260098) and NUREG-1738, ``Technical Study of 
Spent Fuel Pool Accident Risk at Decommissioning Nuclear Power 
Plants,'' dated February 28, 2001 (ADAMS Accession No. ML010430066), 
confirmed that for permanently shutdown and defueled power reactors 
bounded by the assumptions and conditions in the reports, the risk of 
offsite radiological release is significantly less than that for an 
operating power reactor.
    In the past, EP exemptions similar to those requested by SCE, have 
been granted to licensees of permanently shutdown and defueled power 
reactors. However, the exemptions did not relieve the licensees of all 
EP requirements. Rather, the exemptions allowed the licensees to modify 
their emergency plans commensurate with the credible site-specific 
risks that were consistent with a permanently shutdown and defueled 
status. Specifically, for previous permanently shutdown and defueled 
power reactors, the basis for the NRC staff's approval of the 
exemptions from certain EP requirements was based on the licensee's 
demonstration that: (1) The radiological consequences of design-basis 
accidents would not exceed the limits of the U.S. Environmental 
Protection Agency's (EPA) Protective Action Guidelines (PAGs) at the 
exclusion area boundary, and (2) in the unlikely event of a beyond-
design-basis accident resulting in a loss of all modes of heat transfer 
from the fuel stored in the SFP, there is sufficient time to initiate 
appropriate mitigating actions, and if needed, for offsite authorities 
to implement offsite protective actions using a CEMP approach to 
protect the health and safety of the public. Based on precedent 
exemptions, the site-specific analysis should show that there is 
sufficient time following a loss of SFP coolant inventory until the 
onset of fuel damage to implement onsite mitigation of the loss of SFP 
coolant inventory and if necessary, to implement offsite protective 
actions. To meet this criterion, the staff accepted in precedent 
exemptions that the time should exceed 10 hours from the loss of 
coolant until the fuel temperature reaches 900 degrees Celsius 
([deg]C), assuming no air cooling.
    The NRC staff reviewed the licensee's justification for the 
requested exemptions against the criteria in 10 CFR 50.12(a) and 
determined, as described below, that the criteria in 10 CFR 50.12(a) 
are met, and that the exemptions should be granted. An assessment of 
the SCE EP exemptions is described in SECY-14-0144, ``Request by 
Southern California Edison for Exemptions from Certain Emergency 
Planning,'' dated December 17, 2014 (ADAMS Accession No. ML14251A554). 
The Commission approved the NRC staff's recommendation to grant the 
exemptions in the staff requirements memorandum to SECY-14-0144, dated 
March 2, 2015 (ADAMS Accession No. ML15061A521). Descriptions of the 
specific exemptions requested by SCE and the NRC staff's basis for 
granting each exemption are provided in SECY-14-0144 and summarized in 
a table at the end of this document. The staff's detailed review and 
technical basis for the approval of the specific EP exemptions, 
requested by SCE, are provided in the NRC staff's safety evaluation 
dated June 4, 2015 (ADAMS Accession No. ML15082A204).

A. Authorized by Law

    The licensee has proposed exemptions from certain EP requirements 
in 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR part 50, appendix E, 
Section IV, which would allow SCE to revise the SONGS Emergency Plan to 
reflect the permanently shutdown and defueled condition of the station. 
As stated above, in accordance with 10 CFR 50.12, the Commission may, 
upon application by any interested person or upon its own initiative, 
grant exemptions from the requirements of 10 CFR part 50. The NRC staff 
has determined that granting of the licensee's proposed exemptions will 
not result in a violation of the Atomic Energy Act of 1954, as amended, 
or the NRC's regulations. Therefore, the exemptions are authorized by 
law.

B. No Undue Risk to Public Health and Safety

    As stated previously, SCE provided analyses that show the 
radiological consequences of design-basis accidents will not exceed the 
limits of the EPA PAGs at the exclusion area boundary. Therefore, 
formal offsite radiological emergency plans required under 10 CFR part 
50 are no longer needed for protection of the public beyond the 
exclusion area boundary, based on the radiological consequences of 
design-basis accidents still possible at SONGS.
    Although very unlikely, there is one postulated beyond-design-basis 
accident that might result in significant offsite radiological 
releases. However, NUREG-1738 confirms that the risk of beyond-design-
basis accidents is greatly reduced at permanently shutdown and defueled 
reactors. The NRC staff's analyses in NUREG-1738 concludes that the 
event sequences important to risk at permanently shutdown and defueled 
power reactors are limited to large earthquakes and cask drop events. 
For EP assessments, this is an important difference relative to 
operating power reactors, where typically a large number

[[Page 33561]]

of different sequences make significant contributions to risk. Per 
NUREG-1738, relaxation of offsite EP requirements, under 10 CFR part 
50, a few months after shutdown resulted in only a small change in 
risk. The report further concludes that the change in risk due to 
relaxation of offsite EP requirements is small because the overall risk 
is low, and because even under current EP requirements for operating 
power reactors, EP was judged to have marginal impact on evacuation 
effectiveness in the severe earthquakes that dominate SFP risk. All 
other sequences including cask drops (for which offsite radiological 
emergency plans are expected to be more effective) are too low in 
likelihood to have a significant impact on risk.
    Therefore, granting exemptions to eliminate the requirements of 10 
CFR part 50 to maintain offsite radiological emergency plans and to 
reduce the scope of onsite EP activities will not present an undue risk 
to the public health and safety.

C. Consistent With the Common Defense and Security

    The requested exemptions by SCE only involve EP requirements under 
10 CFR part 50 and will allow SCE to revise the SONGS Emergency Plan to 
reflect the permanently shutdown and defueled condition of the 
facility. Physical security measures at SONGS are not affected by the 
requested EP exemptions. The discontinuation of formal offsite 
radiological emergency plans and the reduction in scope of the onsite 
EP activities at SONGS will not adversely affect SCE's ability to 
physically secure the site or protect special nuclear material. 
Therefore, the proposed exemptions are consistent with the common 
defense and security.

D. Special Circumstances

    Special circumstances, in accordance with 10 CFR 50.12(a)(2)(ii), 
are present whenever application of the regulation in the particular 
circumstances is not necessary to achieve the underlying purpose of the 
rule. The underlying purposes of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), 
and 10 CFR part 50, appendix E, Section IV, are to provide reasonable 
assurance that adequate protective measures can and will be taken in 
the event of a radiological emergency, to establish plume exposure and 
ingestion pathway emergency planning zones for nuclear power plants, 
and to ensure that licensees maintain effective offsite and onsite 
radiological emergency plans. The standards and requirements in these 
regulations were developed by considering the risks associated with 
operation of a power reactor at its licensed full-power level. These 
risks include the potential for a reactor accident with offsite 
radiological dose consequences.
    As discussed previously in Section III of this document, because 
SONGS Units 1, 2, and 3 are permanently shutdown and defueled, there is 
no longer a risk of offsite radiological release from a design-basis 
accident and the risk of a significant offsite radiological release 
from a beyond-design-basis accident is greatly reduced when compared to 
the risk at an operating power reactor. In a letter dated March 31, 
2014 (ADAMS Accession No. ML14092A332), the licensee provided analyses 
to demonstrate that the radiological consequences of design-basis 
accidents at SONGS will not exceed the limits of the EPA PAGs at the 
exclusion area boundary. The NRC staff has confirmed the reduced risks 
at SONGS by comparing the generic risk assumptions in the analyses in 
NUREG-1738 to site-specific conditions at SONGS; and has determined 
that the risk values in NUREG-1738 bound the risks presented by SONGS. 
In addition, the significant decay of short-lived radionuclides that 
has occurred since the January 2012 shutdown provides assurance in 
other ways. As indicated by the results of research conducted for 
NUREG-1738 and more recently, for NUREG-2161, ``Consequence Study of a 
Beyond-Design-Basis Earthquake Affecting the Spent Fuel Pool for a U.S. 
Mark I Boiling Water Reactor'' (ADAMS Accession No. ML15255A365), while 
other consequences can be extensive, accidents from SFPs with 
significant decay time have little potential to cause offsite early 
fatalities, even if the formal offsite radiological EP requirements 
were relaxed. The SCE's analysis of a beyond-design-basis accident 
involving a complete loss of SFP water inventory, where adequate fuel 
handling building air exchange with the environment and air cooling of 
the stored fuel is available, shows that by August 31, 2014, air 
cooling of the spent fuel assemblies was sufficient to keep the fuel 
within a safe temperature range, indefinitely, without fuel cladding 
damage or offsite radiological release.
    The only analyzed beyond-design-basis accident scenario that 
progresses to a condition where a significant offsite release might 
occur, involves the very unlikely event where the SFP drains in such a 
way that all modes of cooling or heat transfer are assumed to be 
unavailable, which is postulated to result in an adiabatic heatup of 
the spent fuel. The SCE's analysis of this beyond-design-basis accident 
shows that as of October 12, 2014, more than 17 hours would be 
available between the time the fuel is initially uncovered (at which 
time adiabatic heatup is conservatively assumed to begin), until the 
fuel cladding reaches a temperature of 1652 degrees Fahrenheit ([deg]F) 
(900 [ordm]C), which is the temperature associated with rapid cladding 
oxidation and the potential for a significant radiological release. 
This analysis conservatively does not include the period of time from 
the initiating event causing a loss of SFP water inventory until all 
cooling means are lost.
    The NRC staff has verified SCE's analyses and its calculations. The 
analyses provide reasonable assurance that in granting the requested 
exemptions to SCE, there is no design-basis accident that will result 
in an offsite radiological release exceeding the EPA PAGs at the 
exclusion area boundary. In the unlikely event of a beyond-design-basis 
accident affecting the SFP that results in a complete loss of heat 
removal via all modes of heat transfer, there will be well over 10 
hours available before an offsite release might occur and, therefore, 
at least 10 hours to initiate appropriate mitigating actions to restore 
a means of heat removal to the spent fuel. If a radiological release 
were projected to occur under this unlikely scenario, a minimum of 10 
hours is considered sufficient time for offsite authorities to 
implement protective actions using a CEMP approach to protect the 
health and safety of the public.
    Exemptions from the offsite EP requirements in 10 CFR part 50 have 
previously been approved by the NRC when the site-specific analyses 
show that at least 10 hours are available following a loss of SFP 
coolant inventory accident with no air cooling (or other methods of 
removing decay heat) until cladding of the hottest fuel assembly 
reaches the zirconium rapid oxidation temperature. The NRC staff 
concluded in its previously granted exemptions, as it does with the 
SCE-requested EP exemptions, that if a minimum of 10 hours are 
available to initiate mitigative actions consistent with plant 
conditions, or if needed, for offsite authorities to implement 
protective actions using a CEMP approach, then formal offsite 
radiological emergency plans, required under 10 CFR part 50, are not 
necessary at permanently shutdown and defueled power reactors.
    Additionally, in its letters to the NRC dated October 6, 2014, and 
December 15, 2014, SCE described the SFP makeup strategies that could 
be used in

[[Page 33562]]

the event of a catastrophic loss of SFP inventory. The multiple 
strategies for providing makeup water to the SFP include: using 
existing plant systems for inventory makeup; an internal strategy that 
relies on installed fire water pumps and service water or fire water 
storage tanks; or an external strategy that uses portable pumps to 
initiate makeup flow into the SFPs through a seismic standpipe and 
standard fire hoses routed to the SFPs or to a spray nozzle. These 
strategies will continue to be required as a license condition. 
Considering the very low probability of beyond-design-basis accidents 
affecting the SFP, these diverse strategies provide defense-in-depth 
and time to provide additional makeup or spray water to the SFP before 
the onset of any postulated offsite radiological release.
    For all the reasons stated above, the NRC staff concludes that 
application of certain requirements in 10 CFR 50.47(b), 10 CFR 
50.47(c)(2), and 10 CFR part 50, appendix E, as summarized in the table 
at the end of this document, is not necessary to achieve the underlying 
purpose of these regulations and, therefore, satisfies the special 
circumstances in 10 CFR 50.12(a)(2)(ii). The staff further concludes 
that the exemptions granted by this action will maintain an acceptable 
level of emergency preparedness at SONGS and provide reasonable 
assurance that adequate offsite protective measures, if needed, can and 
will be taken by State and local government agencies using a CEMP 
approach, in the unlikely event of a radiological emergency at the 
SONGS facility. Since the underlying purposes of the rules, as 
exempted, would continue to be achieved, even with the elimination of 
the requirements under 10 CFR part 50 to maintain formal offsite 
radiological emergency plans and the reduction in the scope of the 
onsite EP activities at SONGS, the special circumstances required by 10 
CFR 50.12(a)(2)(ii) exist.

E. Environmental Considerations

    In accordance with 10 CFR 51.31(a), the Commission has determined 
that the granting of these exemptions will not have a significant 
effect on the quality of the human environment, as discussed in the NRC 
staff's Environmental Assessment and Finding of No Significant Impact 
published on April 17, 2015 (80 FR 21271).

IV. Conclusions

    Accordingly, the Commission has determined, pursuant to 10 CFR 
50.12(a), that SCE's request for exemptions from certain EP 
requirements in 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR part 
50, appendix E, Section IV, and as summarized in the table at the end 
of this document, are authorized by law, will not present an undue risk 
to the public health and safety, and are consistent with the common 
defense and security. Also, special circumstances are present. 
Therefore, the Commission hereby grants SCE exemptions from certain EP 
requirements of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR part 
50, appendix E, Section IV, as discussed and evaluated in detail in the 
staff's safety evaluation dated June 4, 2015. The exemptions are 
effective as of June 4, 2015.

    Dated at Rockville, Maryland, this 4th day of June, 2015.

                                         In a nuclear power reactor's
                                          permanently defueled state,
                                          the accident risks are more
                                          similar to an ISFSI or an MRS
                                          than an operating nuclear
                                          power plant. The EP program
                                          would be similar to that
                                          required for an ISFSI under
                                          Section 72.32(a) of 10 CFR
                                          when fuel stored in the spent
                                          fuel pool (SFP) has more than
                                          5 years of decay time and
                                          would not change substantially
                                          when all the fuel is
                                          transferred from the SFP to an
                                          onsite ISFSI. Exemptions from
                                          offsite EP requirements have
                                          previously been approved when
                                          the site-specific analyses
                                          show that at least 10 hours is
                                          available from a partial drain-
                                          down event where cooling of
                                          the spent fuel is not
                                          effective until the hottest
                                          fuel assembly reaches the
                                          zirconium ignition temperature
                                          of 900 degrees Celsius
                                          ([deg]C). The technical basis
                                          that underlies the approval of
                                          the exemption request is based
                                          partly on the analysis of a
                                          time period in which spent
                                          fuel stored in the SFP is
                                          unlikely to reach the
                                          zirconium ignition temperature
                                          in less than 10 hours. This
                                          time period is based on a heat-
                                          up calculation which uses
                                          several simplifying
                                          assumptions. Some of these
                                          assumptions are conservative
                                          (adiabatic conditions), while
                                          others are non-conservative
                                          (no oxidation below 900
                                          [deg]C). Weighing the
                                          conservatisms and non-
                                          conservatisms, the staff
                                          judges that this calculation
                                          reasonably represents
                                          conditions that may occur in
                                          the event of an SFP accident.
                                         The staff concluded that if 10
                                          hours were available to
                                          initiate mitigative actions,
                                          or if needed, offsite
                                          protective actions using a

                                          offsite radiological emergency
                                          plans are not necessary for
                                          these permanently defueled
                                          nuclear power reactor

                                         As supported by the licensee's
                                          SFP analysis, the staff
                                          believes an exemption from the
                                          requirements for formal
                                          offsite radiological emergency
                                          plans is justified for a
                                          zirconium fire scenario
                                          considering the low likelihood
                                          of this event together with
                                          time available to take
                                          mitigative or protective
                                          actions between the initiating
                                          event and before the onset of
                                          a postulated fire.
                                         The SCE analysis has
                                          demonstrated that the
                                          radiological consequences of
                                          design-basis-accidents (DBAs)
                                          will not exceed the limits of
                                          the U.S. Environmental

                                          boundary. These analyses also
                                          show that as of October 12,

                                          a beyond DBA where the hottest

                                          CEMP from the time the fuel is
                                          uncovered until it reaches the
                                          auto-ignition temperature of
                                          900 [deg]C.

                                          The multiple strategies for
                                          providing makeup to the SFP
                                          include: using existing plant
                                          systems for inventory makeup;
                                          an internal strategy that
                                          relies on installed fire water
                                          pumps (two motor-driven and
                                          one diesel-driven) and service
                                          and firewater storage tanks;
                                          or an external strategy that
                                          uses portable pumps to
                                          initiate make-up flow into the
                                          pools through a seismic
                                          standpipe and standard fire
                                          water hoses routed either over
                                          the pools' edges or to spray
                                          nozzles. SCE further provides
                                          that designated on-shift staff
                                          is trained to implement such
                                          strategies and they have plans
                                          in place to mitigate the
                                          consequences of an event
                                          involving a catastrophic loss-
                                          of-water inventory
                                          concurrently from both San

                                          SFPs. It is estimated that it
                                          would take approximately 55
                                          minutes to deliver flow to one
                                          pool, with an additional 35
                                          minutes to provide water to
                                          the second pool without having
                                          to relocate the trailer-
                                          mounted pump. Relocation of
                                          the trailer-mounted pump, if
                                          required, would take
                                          approximately 30 additional
                                          minutes. The SCE will maintain
