SUPPLEMENTARY INFORMATION:

Background

    Regulatory Issue Summary 2000-06, ``Consolidated Line Item 
Improvement Process for Adopting Standard Technical Specification 
Changes for Power Reactors,'' was issued on March 20, 2000. The 
Consolidated Line Item Improvement Process (CLIIP) is intended to 
improve the efficiency and transparency of NRC licensing processes. 
This is accomplished by processing proposed changes to the Standard 
Technical Specifications (STS) in a manner that supports subsequent 
license amendment applications. The CLIIP includes an opportunity for 
the public to comment on proposed changes to the STS following a 
preliminary assessment by the NRC staff and finding that the change 
will likely be offered for adoption by licensees. This notice is 
soliciting comment on a proposed change to the STS that removes 
requirements for the PASS for B&W plants. The CLIIP directs the NRC 
staff to evaluate any comments received for a proposed change to the 
STS and to either reconsider the change or to proceed with announcing 
the availability of the change for proposed adoption by licensees. 
Those licensees opting to apply for the subject change to technical 
specifications are responsible for reviewing the staff's evaluation, 
referencing the applicable technical justifications, and providing any 
necessary plant-specific information. Each amendment application made 
in response to the notice of availability would be processed and 
noticed in accordance with applicable rules and NRC procedures.
    This notice involves the elimination of requirements for PASS and 
related administrative controls in technical specifications for B&W 
plants. This proposed change was proposed for incorporation into the 
standard technical specifications by the B&W Owners Group (BWOG) 
participants in the Technical Specification Task Force (TSTF) and is 
designated TSTF-442. TSTF-442 is supported by the NRC staff's safety 
evaluation dated November 14, 2002, for the BWOG topical report BAW-
2387, ``Justification for the Elimination of the Post Accident Sampling 
System (PASS) from the Licensing Basis of Babcock and Wilcox-Designed 
Plants,'' which was submitted to the NRC on June 25, 2001. The BWOG 
request followed the staff's approval of similar requests for 
elimination of PASS requirements from the Combustion Engineering Owners 
Group (CEOG), the Westinghouse Owners Group (WOG), and the Boiling 
Water Reactor Owners Group (BWROG).

Applicability

    This proposed change to remove requirements for PASS from technical 
specifications (and other elements of the licensing bases) is 
applicable to B&W plants.
    To efficiently process the incoming license amendment applications, 
the staff requests each licensee applying for the changes addressed by 
TSTF-442 using the CLIIP to address the following plant-specific 
verifications and regulatory commitments. The CLIIP does not prevent 
licensees from requesting an alternative approach or proposing the 
changes without the requested verifications and regulatory commitments. 
Variations from the approach recommended in this notice may, however, 
require additional review by the NRC staff and may increase the time 
and resources needed for the review. In making the requested regulatory 
commitments, each licensee should address: (1) That the subject 
capability exists (or will be developed) and will be maintained; (2) 
where the capability or procedure will be described (e.g., severe 
accident management guidelines, emergency operating procedures, 
emergency plan implementing procedures); and (3) a schedule for 
implementation. The amendment request need not provide details about 
designs or procedures.
    Each licensee shall fulfill the actions, verifications or 
commitments that are identified in section 4.0 of the following 
proposed safety evaluation.

Public Notice

    This notice requests comments from interested members of the public 
within 30 days of the date of publication in the Federal Register. 
Following the staff's evaluation of comments received as a result of 
this notice, the staff may reconsider the proposed change or may 
proceed with announcing the availability of the change in a subsequent 
notice (perhaps with some changes to the safety evaluation or proposed 
no significant hazards consideration determination as a result of 
public comments). If the staff announces the availability of the 
change, licensees wishing to adopt the change will submit an 
application in accordance with applicable rules and other regulatory 
requirements. The staff will in turn issue for each application a 
notice of consideration of issuance of amendment to facility operating 
license(s), a proposed no significant hazards consideration 
determination, and an opportunity for a hearing. A notice of issuance 
of an amendment to operating license(s) will also be issued to announce 
the elimination of the PASS requirements for each plant that applies 
for and receives the requested change.

of the Post Accident Sampling System (PASS) From the Licensing Basis of 
Babcock and Wilcox Designed Plants

1.0 Introduction

    In its letter dated June 25, 2001, the BWOG submitted for the NRC 
staff's review topical report BAW-2387,

[[Page 10054]]

``Justification for the Elimination of the Post Accident Sampling 
System (PASS) from the Licensing Basis of Babcock and Wilcox-Designed 
Plants.'' The NRC staff's safety evaluation for the BWOG topical report 
is dated November 14, 2002 (ADAMS Accession Number ML022560119). The 
BWOG proposed elimination of the PASS requirements from the standard 
technical specifications by submitting TSTF-442.
    In the aftermath of the accident at Three Mile Island (TMI), Unit 
2, the Nuclear Regulatory Commission (NRC) imposed requirements on 
licensees for commercial nuclear power plants to install and maintain 
the capability to obtain and analyze post-accident samples of the 
reactor coolant and containment atmosphere. The desired capabilities of 
the Post Accident Sampling System (PASS) were described in NUREG-0737, 
``Clarification of TMI Action Plan Requirements.'' The NRC issued 
orders to licensees with plants operating at the time of the TMI 
accident to confirm the installation of PASS capabilities (generally as 
they had been described in NUREG-0737). A requirement for PASS and 
related administrative controls was added to the technical 
specifications (TS) of the operating plants and was included in the 
initial TS for plants licensed during the 1980s and 90s. Additional 
expectations regarding PASS capabilities were included in Regulatory 
Guide 1.97, ``Instrumentation for Light-Water-Cooled Nuclear Power 
Plants To Assess Plant and Environs Conditions During and Following an 
Accident.''
    Significant improvements have been achieved since the TMI accident 
in the areas of understanding risks associated with nuclear plant 
operations and developing better strategies for managing the response 
to potentially severe accidents at nuclear plants. Recent insights 
about plant risks and alternate severe accident assessment tools have 
led the NRC staff to conclude that some TMI Action Plan items can be 
revised without reducing the ability of licensees to respond to severe 
accidents. The NRC's efforts to oversee the risks associated with 
nuclear technology more effectively and to eliminate undue regulatory 
costs to licensees and the public have prompted the NRC to consider 
eliminating the requirements for PASS in TS and other parts of the 
licensing bases of operating reactors.
    The staff has completed its review of the topical report submitted 
by the Babcock and Wilcox Owners Group (BWOG) that proposed the 
elimination of PASS. The justifications for the proposed elimination of 
PASS requirements center on evaluations of the various radiological and 
chemical sampling and their potential usefulness in responding to a 
severe reactor accident or making decisions regarding actions to 
protect the public from possible releases of radioactive materials. As 
explained in more detail in the staff's safety evaluations for the 
topical report, the staff has reviewed the available sources of 
information for use by decision-makers in developing protective action 
recommendations and assessing core damage. Based on this review, the 
staff found that the information provided by PASS is either unnecessary 
or is effectively provided by other indications of process parameters 
or measurement of radiation levels. The staff agrees, therefore, with 
the owners group that licensees can remove the TS requirements for 
PASS, revise (as necessary) other elements of the licensing bases, and 
pursue possible design changes to alter or remove existing PASS 
equipment.

2.0 Regulatory Evaluation

    The ways in which the requirements and recommendations for PASS 
were incorporated into the licensing bases of commercial nuclear power 
plants varied as a function of when plants were licensed. Plants that 
were operating at the time of the TMI accident are likely to have been 
the subject of confirmatory orders that imposed the PASS functions 
described in NUREG-0737 as obligations. The issuance of plant specific 
amendments to adopt this change, which would remove PASS and related 
administrative controls from TS, would also supersede the PASS specific 
requirements imposed by post-TMI confirmatory orders.
    The NRC staff prepared this model safety evaluation (SE) relating 
to the elimination of requirements on post accident sampling for B&W 
plants and solicited public comments in [insert FR number] in 
accordance with the CLIIP. The use of the CLIIP in this matter is 
intended to help the NRC to efficiently process amendments that propose 
to remove the PASS requirements from TS. Licensees of nuclear power 
reactors to which this model apply were informed that they could 
request amendments conforming to the model, and, in such requests, 
should confirm the applicability of the SE to their reactors and 
provide the requested plant-specific verifications and commitments.

3.0 Technical Evaluation

    The technical evaluations for the elimination of PASS sampling 
requirements are provided in the safety evaluation dated November 14, 
2002, for BWOG topical report BAW-2387. As described in its safety 
evaluation for the topical report, the staff finds that the post-
accident sampling requirements for the following may be eliminated for 
B&W plants:
    1. Reactor coolant dissolved gases.
    2. Reactor coolant hydrogen.
    3. Reactor coolant oxygen.
    4. Reactor coolant chlorides.
    5. Reactor coolant pH.
    6. Reactor coolant boron.
    7. Reactor coolant conductivity.
    8. Radionuclides in the reactor coolant.
    9. Containment atmosphere hydrogen.
    10. Containment atmosphere oxygen.
    11. Radionuclides in the containment atmosphere.
    12. Radionuclides in the containment sump.
    13. Containment sump pH.
    14. Chlorides in the containment sump.
    15. Boron in the containment sump.
    PASS sampling of the above 15 parameters is specified in NUREG-0737 
and RG 1.97. The sampling of the parameters are either not required to 
manage an accident and recover plant conditions, or not necessary due 
to redundancy in sampling capabilities. Based upon the detailed 
justifications provided in topical report BAW-2387 and its associated 
safety evaluation of November 14, 2002, the staff concludes that the 
proposals to eliminate PASS sampling of the above parameters is 
acceptable.
    The staff concludes that sampling of radionuclides is not required 
to support emergency response decision making during the initial phases 
of an accident because the information provided by PASS is either 
unnecessary or is effectively provided by other indications of process 
parameters or measurement of radiation levels. Therefore, it is not 
necessary to have dedicated equipment to obtain this sample in a prompt 
manner.
    The staff does, however, believe that there could be significant 
benefits to having information about the radioisotopes existing post-
accident in order to address public concerns and plan for long-term 
recovery operations. As stated in the safety evaluation for the topical 
report, the staff has found that licensees could satisfy this function 
by developing contingency plans to describe existing sampling 
capabilities and what actions (e.g., assembling temporary shielding) 
may be necessary to obtain and analyze highly radioactive samples from 
the reactor coolant system (RCS), containment sump, and containment 
atmosphere. The use of the contingency plans for obtaining samples 
would depend on the plant conditions

[[Page 10055]]

and the need for information by the decision-makers responsible for 
responding to the accident (see section 4.0 below).
    In addition, the staff considers radioisotope sampling information 
to be useful in classifying certain types of events (such as a 
reactivity excursion or mechanical damage) that could cause fuel damage 
without having an indication of a loss of reactor coolant inventory. 
However, the staff agrees with the topical report's contentions that 
other indicators of failed fuel, such as radiation monitors, can be 
correlated to the degree of failed fuel.
    In lieu of the information that would have been obtained from PASS, 
the staff believes that licensees should maintain or develop the 
capability to monitor radioactive iodines that have been released to 
offsite environs. This information would be useful for decision makers 
trying to assess a release of and limit the public's exposure to 
radioactive materials.
    The staff believes that the changes related to the elimination of 
PASS that are described in the topical report, related safety 
evaluation and this proposed change to TS are unlikely to result in a 
decrease in the effectiveness of a licensee's emergency plan. Each 
licensee, however, must evaluate possible changes to its emergency plan 
in accordance with 10 CFR 50.54(q) to determine if the change decreases 
the effectiveness of its site-specific plan. Evaluations and reporting 
of changes to emergency plans should be performed in accordance with 
applicable regulations and procedures.
    The staff notes that containment hydrogen concentration monitors 
are required by 10 CFR 50.44 and are relied upon to meet the data 
reporting requirements of 10 CFR part 50, Appendix E, section 
VI.2.a.(ii)(3). The staff concludes that these hydrogen monitors 
provide an adequate capability for monitoring containment hydrogen 
concentration during the early phases of an accident. The staff sees 
value in maintaining the capability to obtain grab samples for 
complementing the information from the hydrogen monitors in the long 
term (i.e., by confirming the indications from the monitors and 
providing hydrogen measurements for concentrations outside the range of 
the monitors). The licensee's contingency plan for obtaining highly 
radioactive samples will include sampling of the containment atmosphere 
and may, if deemed necessary and practical by the appropriate decision-
makers, be used to supplement the hydrogen monitors.

    (Note 1--Each licensee should specify a desired implementation 
period for its specific amendment request. The implementation period 
would be that period necessary to develop and implement the items in 
section 4.0 below and, as necessary, to make other changes to 
documentation or equipment to support the elimination of PASS 
requirements. As an alternative, the licensee may choose to have a 
shorter implementation period and include the scheduling of items in 
section 4.0 as part of the regulatory commitments associated with 
this amendment request. Amendment requests that include commitments 
for implementation of the items in section 4 within 6 months of the 
implementation of the revised TS will remain within the CLIIP.)

    (Note 2 --There may be some collateral changes to the TS as a 
result of the removal of the administrative controls section for 
PASS. For example, the elimination of the TS and other regulatory 
requirements for PASS would result in additional changes to TS such 
as (e.g., the renumbering of sections or pages or the removal of 
references). The changes are included in the licensee's application 
to revise the TS in order to take advantage of the CLIIP. The staff 
has reviewed the changes and agrees that the revisions are necessary 
due to the removal of the TS section on PASS. The changes do not 
revise technical requirements beyond that reviewed by the NRC staff 
in connection with the supporting topical reports or the preparation 
of the TS improvement incorporated into the CLIIP.)

4.0 Summary and Licensee Required Actions

    The staff concludes that BAW-2387 provides a sufficient technical 
basis to eliminate sampling the above 15 PASS parameters specified in 
NUREG-0737 and RG 1.97. The staff has identified the following licensee 
required actions, verifications or commitments that must be fulfilled 
by a licensee that eliminates the PASS for sampling the above 15 
parameters in accordance with BAW-2387 and this safety evaluation. The 
licensee shall verify that it has, and make a regulatory commitment to 
maintain, or a regulatory commitment to develop and maintain:
    1. A capability for classifying fuel damage events at the Alert 
level threshold (typically this is 300 microcuries per ml dose 
equivalent iodine). This capability may utilize the normal sampling 
system or correlations of sampling or letdown line dose rates to 
coolant concentrations.
    2. Contingency plans for obtaining and analyzing highly radioactive 
samples of reactor coolant, containment sump, and containment 
atmosphere.
    3. Offsite capability to monitor radioactive iodines.
    The NRC staff finds that reasonable controls for the implementation 
and for subsequent evaluation of proposed changes pertaining to the 
above regulatory commitments are provided by the licensee's 
administrative processes, including its commitment management program. 
Should the licensee choose to incorporate a regulatory commitment into 
the emergency plan, final safety analysis report, or other document 
with established regulatory controls, the associated regulations would 
define the appropriate change-control and reporting requirements. The 
staff has determined that the commitments do not warrant the creation 
of regulatory requirements, which would require prior NRC approval of 
subsequent changes. The NRC staff has agreed that NEI 99-04, Revision 
0, ``Guidelines for Managing NRC Commitment Changes,'' provides 
reasonable guidance for the control of regulatory commitments made to 
the NRC staff. (See Regulatory Issue Summary 2000-17, Managing 
Regulatory Commitments Made by Power Reactor Licensees to the NRC 
Staff, dated September 21, 2000 (ADAMS Accession Number ML003741774).) 
The commitments should be controlled in accordance with the industry 
guidance or comparable criteria employed by a specific licensee. The 
staff may choose to verify the implementation and maintenance of these 
commitments in a future inspection or audit.

5.0 State Consultation

    In accordance with the Commission's regulations, the State official 
was notified of the proposed issuance of the amendments. The State 
official had ((1) no comments or (2) the following comments--with 
subsequent disposition by the staff).

6.0 Environmental Consideration

    The amendments change a requirement with respect to the 
installation or use of a facility component located within the 
restricted area as defined in 10 CFR part 20 and change surveillance 
requirements. The NRC staff has determined that the amendments involve 
no significant increase in the amounts and no significant change in the 
types of any effluents that may be released offsite, and that there is 
no significant increase in individual or cumulative occupational 
radiation exposure. The Commission has previously issued a proposed 
finding that the amendments involve no significant hazards 
consideration, and there has been no public comment on such finding. 
Accordingly, the amendments meet the eligibility criteria for 
categorical exclusion set forth in 10 CFR

[[Page 10056]]

51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact 
statement or environmental assessment need be prepared in connection 
with the issuance of the amendments.

7.0 Conclusion

    The Commission has concluded, based on the considerations discussed 
above, that (1) there is reasonable assurance that the health and 
safety of the public will not be endangered by operation in the 
proposed manner, (2) such activities will be conducted in compliance 
with the Commission's regulations, and (3) the issuance of the 
amendments will not be inimical to the common defense and security or 
to the health and safety of the public.

Proposed No Significant Hazards Consideration Determination

    Description of Amendment Request: The proposed amendments delete 
requirements from the Technical Specifications (and, as applicable, 
other elements of the licensing bases) to maintain a Post Accident 
Sampling System (PASS). Licensees were generally required to implement 
PASS upgrades as described in NUREG-0737, ``Clarification of TMI [Three 
Mile Island] Action Plan Requirements,'' and Regulatory Guide 1.97, 
``Instrumentation for Light-Water-Cooled Nuclear Power Plants to Assess 
Plant and Environs Conditions During and Following an Accident.'' 
Implementation of these upgrades was an outcome of the lessons learned 
from the accident that occurred at TMI, Unit 2. Requirements related to 
PASS were imposed by Order for many facilities and were added to or 
included in the technical specifications (TS) for nuclear power 
reactors currently licensed to operate. Lessons learned and 
improvements implemented over the last 20 years have shown that the 
information obtained from PASS can be readily obtained through other 
means or is of little use in the assessment and mitigation of accident 
conditions.
    Basis for proposed no significant hazards consideration 
determination: As required by 10 CFR 50.91(a), an analysis of the issue 
of no significant hazards consideration is presented below:

Criterion 1--The Proposed Change Does Not Involve a Significant 
Increase in the Probability or Consequences of an Accident Previously 
Evaluated

    The PASS was originally designed to perform many sampling and 
analysis functions. These functions were designed and intended to be 
used in post accident situations and were put into place as a result of 
the TMI-2 accident. The specific intent of the PASS was to provide a 
system that has the capability to obtain and analyze samples of plant 
fluids containing potentially high levels of radioactivity, without 
exceeding plant personnel radiation exposure limits. Analytical results 
of these samples would be used largely for verification purposes in 
aiding the plant staff in assessing the extent of core damage and 
subsequent offsite radiological dose projections. The system was not 
intended to and does not serve a function for preventing accidents and 
its elimination would not affect the probability of accidents 
previously evaluated.
    In the 20 years since the TMI-2 accident and the consequential 
promulgation of post accident sampling requirements, operating 
experience has demonstrated that a PASS provides little actual benefit 
to post accident mitigation. Past experience has indicated that there 
exists in-plant instrumentation and methodologies available in lieu of 
a PASS for collecting and assimilating information needed to assess 
core damage following an accident. Furthermore, the implementation of 
Severe Accident Management Guidance (SAMG) emphasizes accident 
management strategies based on in-plant instruments. These strategies 
provide guidance to the plant staff for mitigation and recovery from a 
severe accident. Based on current severe accident management strategies 
and guidelines, it is determined that the PASS provides little benefit 
to the plant staff in coping with an accident.
    The regulatory requirements for the PASS can be eliminated without 
degrading the plant emergency response. The emergency response, in this 
sense, refers to the methodologies used in ascertaining the condition 
of the reactor core, mitigating the consequences of an accident, 
assessing and projecting offsite releases of radioactivity, and 
establishing protective action recommendations to be communicated to 
offsite authorities. The elimination of the PASS will not prevent an 
accident management strategy that meets the initial intent of the post-
TMI-2 accident guidance through the use of the SAMGs, the emergency 
plan (EP), the emergency operating procedures (EOP), and site survey 
monitoring that support modification of emergency plan protective 
action recommendations (PARs).
    Therefore, the elimination of PASS requirements from Technical 
Specifications (TS) (and other elements of the licensing bases) does 
not involve a significant increase in the consequences of any accident 
previously evaluated.

Criterion 2--The Proposed Change Does Not Create the Possibility of a 
New or Different Kind of Accident From Any Previously Evaluated

    The elimination of PASS related requirements will not result in any 
failure mode not previously analyzed. The PASS was intended to allow 
for verification of the extent of reactor core damage and also to 
provide an input to offsite dose projection calculations. The PASS is 
not considered an accident precursor, nor does its existence or 
elimination have any adverse impact on the pre-accident state of the 
reactor core or post accident confinement of radioisotopes within the 
containment building.
    Therefore, this change does not create the possibility of a new or 
different kind of accident from any previously evaluated.

Criterion 3--The Proposed Change Does Not Involve a Significant 
Reduction in the Margin of Safety

    The elimination of the PASS, in light of existing plant equipment, 
instrumentation, procedures, and programs that provide effective 
mitigation of and recovery from reactor accidents, results in a neutral 
impact to the margin of safety. Methodologies that are not reliant on 
PASS are designed to provide rapid assessment of current reactor core 
conditions and the direction of degradation while effectively 
responding to the event in order to mitigate the consequences of the 
accident. The use of a PASS is redundant and does not provide quick 
recognition of core events or rapid response to events in progress. The 
intent of the requirements established as a result of the TMI-2 
accident can be adequately met without reliance on a PASS.
    Therefore, this change does not involve a significant reduction in 
the margin of safety.
    Based upon the reasoning presented above and the previous 
discussion of the amendment request, the requested change does not 
involve a significant hazards consideration.

    Dated in Rockville, Maryland, this 21st day of February, 2003.
