NUCLEAR REGULATORY COMMISSION

10 CFR Parts 50 and 140

RIN 3150-AF79


Financial Protection Requirements for Permanently Shutdown 
Nuclear Power Reactors

AGENCY: Nuclear Regulatory Commission.

ACTION: Proposed rule.

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

SUMMARY: The Nuclear Regulatory Commission (NRC) is proposing to amend 
its regulations to allow nuclear reactor licensees to reduce onsite and 
offsite liability coverage during permanent shutdown of the reactors if 
they meet specified reactor configurations. This proposed amendment 
would reduce the level of insurance coverage commensurate with the risk 
reduction after the appropriate spent fuel cooling period following 
permanent shutdown of the reactor.

DATES: The comment period expires January 13, 1998. Comments received 
after this date will be considered if it is practical to do so, but the 
Commission is able to assure consideration only for comments received 
on or before this date.

SUPPLEMENTARY INFORMATION:

Background

    The current regulations governing insurance coverage for nuclear 
power reactors are contained in 10 CFR 50.54(w) and 10 CFR 140.11. 
These regulations do not take into consideration the reduced risk 
associated with permanently shutdown plants. The exemption process 
allows reduced insurance coverage for these plants.
    Consideration of whether financial protection coverage should be 
reduced for permanently shutdown plants must take into account the 
preservation of the solvency of the organization responsible for 
maintaining and decommissioning these facilities in the unlikely event 
of a nuclear incident. In addition, consideration would be given to 
timely payment for valid damage claims by members of the public and 
minimization of the likelihood that Federal Government indemnity would 
be exercised for satisfaction of claims for damages.
    The regulations in 10 CFR 140.11 require that the licensees of 
facilities designed to produce substantial amounts of electricity, a 
rated capacity of 100,000 kWe or more, must have and maintain a primary 
insurance coverage of $200 million from private sources to protect 
against offsite liability. In addition, licensees must maintain 
secondary financial protection in the form of private liability 
insurance available under an industry retrospective rating plan. The 
current maximum obligation for secondary financial protection for a 
licensee in this plan is $75.5 million with respect to any nuclear 
incident. Thus, the total financial protection for offsite liability 
for any incident would be the primary layer of $200 million, plus the 
secondary layer of $75.5 million multiplied by the number of licensed 
power reactors with a rated capacity of 100,000 kWe or higher.
    Under 10 CFR 50.54(w), power reactor licensees must obtain 
insurance coverage from private sources to provide protection against 
onsite damage in the event of an accident. These monies would allow the 
licensee to stabilize and decontaminate the reactor and reactor station 
site in the event of an accident. The minimum amount of insurance 
coverage is the lesser of $1.06 billion or the maximum amount of 
insurance generally available from private sources.
    This proposed rule is part of the NRC effort to eliminate 
unnecessary regulatory burdens for power reactor facilities that are 
permanently shutdown and in the process of decommissioning. This would 
complement other amendments for decommissioning, such as the final rule 
that was published in the Federal Register (61 FR 39278) on July 29, 
1996, which clarified the procedures leading to permanent shutdown and, 
eventually, to the termination of an operating license for nuclear 
power reactors.
    This proposed rule would also address a petition for rulemaking 
(PRM-50-57) submitted by the North Carolina Public Staff Utilities 
Commission. The petition requested reduction or, preferably, 
elimination of the $1.06 billion of insurance for onsite reactor 
stabilization and accident decontamination that is required by 10 CFR 
50.54(w) when all nuclear fuel has been removed from the site. The 
petitioner also requested that the offsite primary and secondary 
liability coverages required under 10 CFR 140.11(a)(4) be reduced or, 
preferably, eliminated for shutdown reactors when no nuclear fuel is on 
the reactor site.
    The proposed rule does not address the financial protection 
requirements for

[[Page 58691]]

Independent Spent Fuel Storage Installations (ISFSIs). This subject 
will be addressed after efforts dealing with technical and licensing 
issues for ISFSIs are resolved in areas of safeguards requirements, 
emergency planning, and potential fuel storage handling activities.

Discussion

    Several different configurations for permanently shutdown reactors 
are being established that encompass anticipated spent fuel 
characteristics and storage modes during the period between permanent 
shutdown and termination of the license. They are as follows:
    Reactor Configuration 1: the reactor is defueled, permanently 
shutdown, and spent fuel in the spent fuel pool is susceptible to a 
zircaloy cladding fire if the spent fuel pool is drained accidentally. 
This configuration encompasses the period from immediately after the 
core is offloaded to just before the decay heat of the hottest 
assemblies is low enough that no rapid zircaloy oxidation will take 
place, and the fuel cladding will remain intact with no gap release if 
water in the spent fuel pool is lost.
    Reactor Configuration 2: The reactor is defueled, permanently 
shutdown, and spent fuel is in the spent fuel pool but is not 
susceptible to a zircaloy cladding fire or gap release caused by an 
incipient fuel cladding failure in the event the spent fuel pool is 
drained accidentally. In this configuration, the spent fuel can be 
stored long-term in the spent fuel pool without the possibility of 
initiating a zircaloy fire or significant fuel cladding failure. In 
addition, the site may contain a radioactive inventory of liquid 
radwaste, activated reactor components, and contaminated structural 
materials. The radioactive inventory during this configuration may 
change depending on the licensee's proposed shutdown activities and 
schedule.
    Reactor Configuration 3: The reactor is permanently shutdown and no 
spent fuel is in the reactor or the spent fuel pool. All spent fuel has 
been removed to an offsite or onsite dry storage independent spent fuel 
storage installation (ISFSI) or to a DOE high-level repository. The 
remaining radioactive inventory depends on the decommissioning status 
and may include liquid radwaste, activated reactor components, and 
contaminated structural materials.
    Reactor Configuration 4: Same as reactor configuration 3, except 
the reactor site has no significant mobile sources of radioactivity 
such as contaminated liquids (less than 1000 gallons).
    There are potential onsite and offsite radiological consequences 
that could be associated with the onsite storage of the spent fuel in 
the spent fuel pool for some time after permanent shutdown. In Reactor 
Configuration 1, in the event of a complete loss of spent fuel pool 
coolant inventory such as from a beyond-design-basis earthquake 
scenario, there is a potential for overheating the fuel by decay heat. 
This sequence could result in a zircaloy cladding fire that may have 
significant onsite and offsite consequences.
    To prevent fuel rod cladding failure leading to a zircaloy-cladding 
fire if all spent fuel pool water is lost, the rod cladding temperature 
must not exceed 565 deg.C. The rod cladding temperature is an important 
factor that must be considered in modifying the financial protection 
requirements for permanently shutdown reactors.
    In Reactor Configuration 2, the spent fuel has decay heat 
sufficiently low that the cladding will remain intact even if all spent 
fuel pool water is lost. However, if there are significant sources of 
radioactive material stored onsite, it would be appropriate to maintain 
an adequate level of onsite insurance coverage. Although the offsite 
consequences are negligible in the Reactor Configuration 2 , because 
the spent fuel pool is operational and an inventory of radioactive 
materials exists onsite, an appropriate level of offsite financial 
protection is required to account for the potential for significant 
judgments or settlements from litigation that might be instituted and 
to protect the Federal government from indemnity claims.
    In Reactor Configuration 3, when spent fuel is no longer stored in 
the spent fuel pool, the potential for a radiological incident is 
primarily in mobile sources of radioactivity onsite at permanently 
shutdown nuclear reactors. The offsite cleanup costs were found to be 
negligible for Reactor Configuration 3, but as was noted in Reactor 
Configuration 2, an appropriate level of offsite financial protection 
is still required to account for the potential for significant 
judgments or settlements from litigation that might be instituted and 
also to protect the Federal government from indemnity claims. Because 
the level of risk has decreased vis-a-vis the Reactor Configuration 2 
by having no spent fuel in the spent fuel pool, the level of offsite 
financial protection required is being reduced by taking into account 
only the mobile radioactive inventory onsite.
    In the Reactor Configuration 4, with no significant amount of 
mobile sources of radioactivity such as contaminated liquids onsite, 
there is no need to maintain the same level of insurance coverage for 
onsite or offsite financial protection as in Reactor Configuration 3. 
The basis for the transition from Reactor Configuration 3 to Reactor 
Configuration 4 is the point at which there is less than 1000 gallons 
of liquid radwaste stored onsite. A limiting value of 1000 gallons has 
been considered because it constitutes approximately a factor of 500 
reduction in volume from the large volume tank used as the basis for 
the Reactor Configuration 3 limiting event.
    In Reactor Configuration 4, if the licensee has cleaned the site to 
unrestricted release levels and is awaiting a confirmatory survey for 
terminating the license, the necessary level of onsite insurance 
coverage at this stage would be less than when 1000 gallons of liquid 
radwaste were stored onsite. Under these circumstances, the onsite 
coverage could be further reduced or eliminated to account for 
negligible onsite consequences. However, for offsite financial 
protection requirements, although the offsite consequences are 
negligible, some level of public liability financial protection must be 
maintained as long as there remains in effect a nuclear reactor license 
issued pursuant to 10 CFR part 50 under the authority of Section 103 or 
104 of the Atomic Energy Act (42 U.S.C. 2133, 2134). See Section 170a 
of that Act (42 U.S.C. 2210a). Section 170 is commonly referred to as 
the ``Price-Anderson Act.''

Proposed Regulatory Action

    The proposed amendments would adjust the onsite insurance coverage 
requirements and the offsite financial protection requirements for 
permanently shutdown reactors based on limiting the spent fuel cladding 
temperatures for accidents involving loss of spent fuel pool water and 
the amount of onsite radioactive inventory such as liquid radwaste in 
post shutdown modes. The insurance amounts are based on the estimated 
cost of recovery from limiting hypothetical events for specific reactor 
configurations.
    The proposed amendments would also address ``rated capacity'' in 10 
CFR 140.11 as used in Section 170a of the Atomic Energy Act to indicate 
that a permanently shutdown nuclear reactor has a ``rated capacity'' of 
zero.
    The proposed financial protection requirements are as follows.
    Reactor Configuration 1--Fuel in spent fuel pool not sufficiently 
cool.

[[Page 58692]]

--The requirements for onsite insurance coverage and offsite financial 
protection remain as presently specified in 10 CFR 50.54(w) and 10 CFR 
140.11, respectively.

    Reactor Configuration 2--Fuel could tolerate a complete loss of 
water in the spent fuel pool.

--The onsite insurance coverage requirements is $50 million. The amount 
of $50 million is to recover from a postulated accident in the spent 
fuel pool.
--The offsite financial protection requirement is $100 million, based 
on the potential for significant judgments or settlements resulting 
from litigation despite negligible offsite consequences.

    Reactor Configuration 3--No fuel in spent fuel pool, risk dependent 
on radioactive inventory at plant site in decommissioning status.

--The onsite insurance coverage requirement is $50 million. The amount 
of $50 million is the estimated amount needed to recover from a 
postulated onsite event of a rupture of a large slightly contaminated 
liquid storage tank.
--The offsite financial protection requirement is $50 million, based on 
the potential for significant judgments or settlements resulting from 
litigation that might still be instituted despite negligible offsite 
consequences; however the liability risk is considered less than in 
Reactor Configuration 2.

    Reactor Configuration 4--No fuel in the spent fuel pool and no 
significant source of mobile radioactive material.

--The onsite insurance coverage requirements is either $25 million or 
is eliminated. The amount of $25 million is based on the possibility of 
having to clean up onsite contamination from an accidental rupture of a 
less-than-1000-gallon contaminated liquid storage tank during shutdown 
activities. Elimination of onsite insurance coverage would be warranted 
when a licensee is awaiting a confirmatory survey for license 
termination.
--The offsite financial protection requirement is $25 million, based on 
the potential for claims arising from asserted offsite consequences. 
This would minimize the possibility that Federal Government 
indemnification would be required. As noted above, the Atomic Energy 
Act does not allow a 10 CFR part 50 licensee to drop this coverage 
entirely, only to reduce it.

Discussion

    This proposed rule would allow power reactor licensees to reduce 
their onsite insurance coverage and offsite financial protection 
requirements during permanent shutdown without resorting to the 
exemption process. The level of financial protection would be 
determined for permanently shutdown reactors at a level that coincides 
with their actual configuration stage.
    During Reactor Configuration 1, licensees would be required to 
maintain onsite insurance coverage and offsite financial protection at 
the levels currently required by 10 CFR 50.54(w) and 10 CFR 140.11, 
respectively. This is because the radiological consequences during this 
stage of permanent shutdown approximate the magnitude of a severe core 
damage accident.
    After allowing the spent fuel to cool down to the point that the 
maximum spent fuel cladding temperature will not exceed 565 deg.C in 
the event of a loss of water in the spent fuel pool (Reactor 
Configuration 2), power reactor licensees would be allowed under 10 CFR 
50.54(w) to reduce their onsite insurance coverage from $1.06 billion 
to $50 million. The reason for this reduction in insurance coverage is 
that the rapid clad oxidation event of Reactor Configuration 1 is not 
possible. Insurance coverage requirements for Reactor Configuration 2 
are based on the fact that there is a possibility for a fuel handling 
accident in the spent fuel pool, and significant amounts of mobile 
radioactive sources remain onsite that have a potential for release 
during this period. The $50 million coverage would be adequate to clean 
up the site in the event of a fuel handling accident, an accidental 
release of cooling water from the spent fuel pool, or a rupture of a 
large slightly contaminated liquid storage tank.
    The proposed insurance coverage requirement for Reactor 
Configuration 2 does not take into account the reduction in radioactive 
decay of the spent fuel assemblies with the passage of time during that 
period. The insurance coverage requirements are based on the 
conservative assumption of a fuel handling accident shortly after the 
transition to Reactor Configuration 2. Adjusting insurance requirements 
during Reactor Configuration 2 based on the decay level of the spent 
fuel would be burdensome from a regulatory standpoint, as opposed to 
selecting a bounding figure to encompass any unexpected events 
concerning the spent fuel pool.
    In Reactor Configuration 2, the offsite financial protection 
requirements set forth in 10 CFR 140.11 would be reduced from $200 
million to $100 million for the primary liability coverage, and the 
licensee would be allowed to withdraw from the secondary liability 
coverage under Price-Anderson.
    In Reactor Configuration 3, when all the spent fuel has been 
removed to an onsite or offsite dry storage ISFSI or to a DOE high-
level repository and the onsite radioactive inventory is greater than 
1000 gallons, the onsite insurance coverage requirements would be $50 
million under the proposed 10 CFR 50.54(w). This amount is based on the 
fact that there are still mobile radioactive sources onsite that have 
the potential to contaminate the site. The maximum cleanup costs 
associated with Reactor Configuration 3 are estimated at approximately 
$50 million. The conservative limiting event is the rupture of a large 
contaminated liquid storage tank that causes soil contamination and the 
potential to contaminate groundwater. The offsite financial protection 
requirements under the proposed Section 140.11 would be reduced from 
$100 million to $50 million, and the licensee would not be required to 
maintain secondary liability coverage under the Price-Anderson Act for 
Reactor Configuration 3. With no spent fuel in the spent fuel pool, the 
risks of offsite contamination have been reduced considerably for this 
configuration.
    In Reactor Configuration 4, there are no significant mobile sources 
of radioactivity, such as liquid contaminants, onsite. Thus, the 
potential for onsite and offsite radiological impacts is limited. In 
this situation, onsite insurance coverage requirements either would be 
$25 million or would be completely eliminated under the proposed 10 CFR 
50.54(w). The amount in each case would be based on information 
provided by the licensee and evaluated by the staff for the particular 
circumstances of the shutdown reactor. The $25 million onsite insurance 
coverage would be required if liquid radwaste remained stored onsite, 
usually 1,000 gallons or less of radwaste, that may be susceptible to 
an accidental spill and the consequent need for cleanup of the 
contaminated site. Elimination of required onsite insurance coverage 
would be based on the licensee's submittal of its terminal radiation 
survey to the NRC stating that the site has been cleaned to 
unrestricted release levels and is awaiting a confirmatory survey for 
termination of the license. In either case, the onsite and offsite 
consequences would be negligible.

[[Page 58693]]

    In Reactor Configuration 4, the required offsite financial 
protection would be reduced to $25 million to account for the 
continuing potential for claims based on asserted offsite consequences. 
A minimum of $25 million in coverage would minimize the possibility 
that Federal Government indemnification would be required and would be 
consistent with the requirements of Section 170 of the Atomic Energy 
Act that power reactor licensees maintain some level of public 
liability financial protection. The licensee would not be required to 
maintain secondary liability coverage under Price-Anderson for Reactor 
Configuration 4.
    In addition, ``rated capacity'' would be addressed in 10 CFR part 
140 to indicate that permanently shutdown nuclear power plants have 
``zero'' rated capacity. The effect of this amendment would be to allow 
the NRC to permit reduction of the primary liability coverage and 
elimination of the requirement for participation in the secondary 
liability coverage for nuclear power plants that had made the 
certifications under 10 CFR 50.82(a)(1)(i) and (ii). However, for 
reasons stated above, the NRC does not propose to permit this reduction 
and withdrawal until a reactor has entered the Reactor Configuration 2. 
At that point the NRC proposes that the reactor no longer be subject to 
the requirements to maintain primary financial protection in the 
``maximum amount available at reasonable cost and on reasonable terms 
from private sources'' or to participate in the secondary financial 
protection public liability system under Section 170 of the Atomic 
Energy Act. The Commission has already approved, in response to site-
specific requests, these adjustments in the primary and secondary 
public liability insurance regime, and this clarification in part 140, 
as requested by the Commission, places into the Commission's 
regulations a statement that a permanently shutdown nuclear power plant 
is no longer considered to have any ``rated capacity.''
    The petition for rulemaking submitted by the North Carolina Public 
Staff Utilities Commission would be substantially granted in that the 
insurance requirements would be significantly reduced, as requested. 
However, the petition could not be fully granted because of the Price-
Anderson statutory provisions that do not allow licensees who continue 
to hold 10 CFR part 50 licenses to drop the offsite public liability 
coverage entirely.

Finding of No Significant Environmental Impact: Availability

    The Commission has determined under the National Environmental 
Policy Act of 1969, as amended, and the Commission's regulations in 
subpart A of 10 CFR part 51, that this rule, if adopted, would not be a 
major Federal action significantly affecting the quality of the human 
environment, and therefore, an environmental impact statement is not 
required. The proposed rule change would allow licensees to seek 
reductions in onsite and offsite insurance coverage following permanent 
shutdown if they meet specified reactor configurations because of the 
reduced risk associated with permanently shutdown reactors. The 
proposed rule change would require no changes in hardware, procedures, 
organization, or operation of nuclear power reactors. It would not 
affect the safety requirements for nuclear power reactors because of 
the significantly reduced risks to the public health and safety in 
Reactor Configurations 2, 3, and 4 and it would not affect the 
likelihood, magnitude, or consequences of accidents at the permanently 
shutdown nuclear power reactors. Although the proposed rule change 
would reduce the level of financial protection available to pay for 
environmental or other consequences that may result from accidents at 
permanently shutdown nuclear power reactors, the Commission considers 
the reduced required insurance and financial protection coverage to be 
fully adequate and commensurate with the reduced consequences of 
potential accidents at permanently shutdown nuclear reactors and that 
the environment will not be negatively affected. Accordingly, the 
Commission has determined that the proposed rulemaking would have no 
significant impacts on the quality of the environment.
    The environmental assessment and finding of no significant impact 
on which this determination is based are available for inspection at 
the NRC Public Document Room, 2120 L Street NW. (Lower Level), 
Washington, DC. Single copies of the environmental assessment and the 
finding of no significant impact are available from George Mencinsky, 
Office of Nuclear Regulatory Research, U.S. Nuclear Regulatory 
Commission, Washington, DC 20555-0001, telephone (301) 415-6206.

Paperwork Reduction Act Statement

    This proposed rule does not contain a new or amended information 
collection requirement subject to the Paperwork Reduction Act of 1995 
(44 U.S.C. 3501 et seq.). Existing requirements were approved by the 
Office of Management and Budget, approval numbers 3150-0011 and 3150-
0039.

Public Protection Notification

    The NRC may not conduct or sponsor, and a person is not required to 
respond to, an information collection unless it displays a currently 
valid OMB control number.

Regulatory Analysis

    The Commission has prepared a draft regulatory analysis on this 
proposed regulation. The analysis examines the costs and benefits of 
the alternatives considered by the Commission. The draft analysis is 
available for inspection in the NRC Public Document Room, 2120 L Street 
NW. (Lower Level), Washington, DC. Single copies of the draft analysis 
may be obtained from George Mencinsky, Office of Nuclear Regulatory 
Research, U.S. Nuclear Regulatory Commission, Washington, DC 20555-
0001, telephone (301) 415-6206. The Commission requests public comment 
on the draft regulatory analysis. Comments on the draft analysis may be 
submitted to the NRC as indicated under the ADDRESSES heading.

Regulatory Flexibility Certification

    As required by the Regulatory Flexibility Act of 1980 (5 U.S.C. 
605(b)), the Commission certifies that this rule, if adopted, will not 
have a significant economic impact upon a substantial number of small 
entities. The proposed rule only affects NRC power reactor licensees, 
which are not ``small entities.''

Backfit Analysis

    The NRC has determined that the backfit rule, 10 CFR 50.109, does 
not apply to this proposed rule because the backfit rule is limited in 
scope to construction and operation of nuclear reactors. This rule 
would only apply to reactors that have permanently ceased operations. 
Therefore, a backfit analysis is not required because these amendments 
do not involve any provisions that would impose backfits as defined in 
10 CFR 50.109(a)(1).

    2. In Sec. 50.54(w), paragraph (5) is added to read as follows:


Sec. 50.54  Conditions of licenses.

* * * * *
    (w) * * *
    (5) For the specified reactor configurations during permanent 
shutdown, licensees shall maintain the following insurance requirements 
notwithstanding paragraph (w)(1):
    (i) For Reactor Configuration 1: when the reactor is defueled, 
permanently shutdown, and the spent fuel cladding temperature in the 
spent fuel pool is 565 deg.C or greater for a postulated loss of spent 
fuel pool cooling event, the insurance coverage must be as specified in 
paragraph (w)(1).
    (ii) For Reactor Configuration 2: when the reactor is defueled and 
permanently shutdown, no operating reactors are on the site, and the 
spent fuel cladding temperature in the spent fuel pool does not exceed 
565 deg.C for a postulated loss-of-spent-fuel-pool-cooling event, the 
minimum insurance coverage limit for each reactor must be $50 million.
    (iii) For Reactor Configuration 3: when the reactor is defueled and 
permanently shutdown, no operating reactors are on the site, no fuel is 
in the spent fuel pool, and the radioactive liquid inventory onsite is 
1,000 gallons or greater, the minimum insurance coverage for each 
reactor must be $50 million.
    (iv) For Reactor Configuration 4: when the reactor is defueled and 
permanently shutdown, no operating reactors are on the site, no fuel is 
in the spent fuel pool, and the radioactive liquid inventory onsite is 
less than 1,000 gallons, the minimum insurance coverage for each 
reactor must be $25 million. For sites awaiting license termination, no 
insurance coverage is required if the licensee has completed its 
terminal radiation survey and the site is ready for the confirmatory 
survey for license termination.

    (a) * * *
    (5) For the specified reactor configurations during permanent 
shutdown of nuclear power reactors (such reactors being classified as 
having zero electric power level rated capacity) that were covered 
during their operation by paragraph (a)(4):
    (i) For Reactor Configuration 1: when the reactor is defueled, 
permanently shutdown, and the spent fuel cladding temperature in the 
spent fuel pool is 565 deg.C or greater for a postulated loss of spent 
fuel pool cooling event, in the amount as specified in paragraph 
(a)(4).
    (ii) For Reactor Configuration 2: when the reactor is defueled and 
permanently shutdown, no operating reactors are on the site, and the 
spent fuel cladding temperature in the spent fuel pool does not exceed 
565 deg.C for a postulated loss-of-spent-fuel-pool-cooling event, in 
the amount of $100 million for each reactor.
    (iii) For Reactor Configuration 3: when the reactor is defueled and 
permanently shutdown, no operating reactors are on the site, no fuel is 
in the spent fuel pool, and the radioactive liquid inventory onsite is 
1,000 gallons or greater, in the amount of $50 million for each 
reactor.
    (iv) For Reactor Configuration 4: when the reactor is defueled and 
permanently shutdown, no operating reactors are on the site, no fuel is 
in the spent fuel pool, and the radioactive liquid inventory onsite is 
less than 1,000 gallons, in the amount of $25 million for each reactor.
