May 30, 1997 MEMORANDUM T0: Chairman Jackson Commissioner Rogers Commissioner Dicus Commissioner Diaz Commissioner McGaffigan FROM:

L. Joseph Callan Executive Direct r r Operations 1

SUBJECT:

SEMIANNUAL STATUS REPORT ON THE FIRE PROTECTION TASK ACTION PLAN AND PLANT-SPECIFIC THERM 0-LAG CORRECTIVE ACTION PROGRAMS The fourth semiannual report on the status of the Fire Protection Task Action Plan (FP-TAP) is attached (Attachment 1).

Since the previous status report (memorandum of October 31, 1996, from James M. Taylor. Executive Director for Operations, to the Commission), the staff has worked on the risk-informed, performance-based fire protection rulemaking; the fire protection functional inspection program; and the self-induced station blackout study.

As reported in the previous status report, the staff has completed the Thermo-Lag Action Plan, but continues to monitor plant-specific Thermo-Lag corrective action plans and schedules. The licensees for 44 units have informed the staff that all corrective actions are complete.

The licensees for 16 units have committed to completion dates in 1997. The completion dates for the remaining units are:

1998 (9 units). 1999 (9 units), and 2000 (4 units).

See Attachment 2 for a summar/ of the plant-specific completion schedules and Attachment 3 for the detailed status of plant-specific corrective actions.

Since the previous status report, the staff has met with the licensees with completion schedules that extend beyond 1997.

The staff will meet with the licensee for Crystal River 3 during May 1997.

During the meetings, the staff requested additional information from the licensees for Limerick 1/2: Peach Bottom 2/3: Oyster Creek: Sequoyah 1/2: Susquehanna 1/2: Turkey Point 3/4: and Washington Nuclear Project 2.

'the staff will have followup meetings with the licensees for Limerick. Peach Bottom. Sequoyah, and Turkey Point.

For the remaining plants, on the basis of information submitted by the licensees and provided during the meetings, the staff has concluded that the schedules are reasonable.

For those commitments that extend beyond 1997, the staff is considering issuing confirmatory orders to ensure schedules are met. After the staff completes the meetings and considers the additional information it

)

requested it will provide a Japer to the Commission with its conclusions and its plans for ensuring that t1e licensees continue to make progress towards

//

overall resolution of the Thermo-Lag issue and meet their schedular

/

commitments.

-s The Commissioners In July 1996, the staff issued NUREG-1552. " Fire Barrier Penetration Seals in Nuclear Power Plants." which documented its technical assessment of

)enetration seals. As a result of recent Congressional inquiries, the staff l

las initiated an assessment of seal problems reported since it nerformed the assessment discussed in the NUREG report.

The staff will use the insights from this effort to determine if additional NRC or industry actions on fire barrier penetration seals is needed.

This effort is not a part of the FP-TAP but is being tracked by the staff in a separate mini action plan.

It should be noted that an assessment of penetration seals is part of the recently developed Fire Protection Functional Inspection procedure.

i ATTACHMENT 1 SEMIANNUAL STATUS REPORT ON THE FIRE PROTECTION TASK ACTION PLAN OFFICE OF NUCLEAR REACTOR REGULATION FIRE PROTECTION ENGINEERING SECTION 1

INTRODUCTION During July 1992, the U.S. Nuclear Regulatory Comission (NRC) staff developed

'the Thermo-Lag Action Plan to address generic issues related to the use by

> nuclear reactor licensees of Thermo-Lag 330-1 fire barriers.

Later, the staff j

reassessed the NRC reactor fire protection program in response to programmatic concerns it raised during its review of Thermo-Lag fire barriers. The staff presented its findings in " Report on the Reassessment of the NRC Fire l

Protection Program," February 27, 1993. The Fire Protection Task Action Plan i

(FP-TAP) addresses implementation of the recomendations made in the reassessment report. The FP-TAP tracks the. implementation of a wide range of technical and programatic fire protection issues.

It includes.

recomendations for action (Part I), recommendations for further study

.(Part II), confirmation issues (Part III), and lessons learned (Part IV).

The status of each part of the FP-TAP, along with important accomplishments, is' presented in Section 2 of this fourth semiannual report. The previous status report was attached to a memorandum of October 31, 1996, from James M. Taylor, Executive Director for Operations, to the Comission.

In the future, the staff will issue status reports annually.

)

Each operating reactor has an NRC-approved fire protection plan.that conforms to 10 CFR 50.48, " Fire protection," and General Design Criterion 3, " Fire i

protection," and satisfies the defense-in-depth concept.

Licensees have also implemented Generic Letter 86-10 (i.e., incorporated the NRC-approved fire I

protection plan into the updated safety analysis report, removed certain i

aspects of the fire protection plan from technical specifications, and adopted a standard fire protection license condition). When fire protection features i

are degraded or inoperable, the licensees implement NRC-approved measures, such as fire watches, to compensate for the condition. This combination of a defense-in-depth fire protection plan and compensatory measures ensures that an adequate level of fire protection is maintained at each operating reactor while the staff is completing the FP-TAP.

~ 2.1.2 Fire Barrier Systems Other Than Thermo-Lag (Ongoing)

As reported in the status report of October 31, 1996, the staff has completed

.its small-scale fire barrier scoping tests at the National Institute of Standards and Technology (reference " Report of Test FR 4008"). Hindered by competing priorities, the staff did not complete its review of the test results during the reporting period. However, the staff plans to complete this effort before'the next status report.

2.1.3 Coordination of Fire Protection Inspections (Complete)

In a memorandum to the Comission (September 20,1995), the staff informed the Commission that it would develop and implement the fire protection functional inspection (FPFI) program as outlined in SECY-95-034, '% atus of Recommendations Resulting From the Reassessment of the NRC Fire Protection Program" (February 13,1995), to address the reassessment recommendation that the staff. reevaluate the scope of the reactor fire protection inspection program and develop a coordinated a)proach for the fire protection and safe-shutdown systems inspections.

In t1e status report of October 31, 1996, the staff stated that it would give the Commission the details of the FPFI program and staff plans for implementing it.

In SECY-96-267, " Fire Protection Functional Inspection Program" (December 24,1996), the staff satisfied this commitment. Later, in a Staff Requirements Memorandum (SRM) of February 7,1997, the Comission approved the staff's plans and directed the staff to proceed with the four pilot inspections.

River Bend will be inspected in June 1997, Clinton in August 1997, Susquehanna in October 1997, and St. Lucie in March 1998. The staff is currently.

completing the FPFI procedures and guidelines. 'The procedure will be issued as a Temporary Instruction (TI)' in early June, preceding the River Bend FPFI.

In accordance with SECY-96-267 and the SRM of February 7, 1997, the staff will give the Conaission the FPFI procedures for-information preceding the River Bend FPFI and will also give the Commission a post-pilot inspection program report describing inspection results and discussing ways to expand the benefits of the, pilot inspections to all licensees (e.g., licensee self-assessments).

2.1.4 Self-Induced Station Blackout Study (Ongoing)

The staff, with the technical assistance of Brookhaven National Laboratory (BNL), has developed a >robabilistic risk assessment (PRA) model for assessing the risk associated wit 1' post-fire safe-shutdown methodologies that impose a self-induced station blackout. As reported in the status report'of l

October 31, 1996, the staff presented the draft station blackout study to the Advisory Committee on Reactor Safeguards (ACRS) on February 29, 1996. Since that status report, the staff has considered the recommendations made by the L

ACRS and has submitted a revised scope of work to BNL addressing the ACRS recommendations. After the staff modifies its contract with BNL, it plans to l

^

l apply the PRA model to two plant-specific cases.

2.3 Confirmation Issu.g3 (Complete) 4 r

l Part III of tiie reassessment report recommended that the staff perform a programmatic assessment of the fire protection review and inspection programs, o

The FPFI program (see Section 2.1.3 above) addresses this recommendation. As reported in the status report of October 31, 1996, the remaining Part III issues are now being tracked in the fire protection rulemaking action plan.

Therefore, Part III of the FP-TAP is complete.

The Commissioners i In July 1996, the staff issued NUREG-1552. " Fire Barrier Penetration Seals in Nuclear Power Plants." which documented its technical assessment of 3enetration seals. As a result of recent Congressional inquiries, the staff las initiated an assessment of seal problems reported since it aerformed the assessment discussed in the NUREG report.

The staff will use tie insights i

from this effort to determine if additional NRC or industry actions on fire barrier penetration seals is needed.

This effort is not a part of the FP-TAP but is being tracked by the staff in a separate mini action plan.

It should be noted that an assessment of penetration seals is part of the recently developed Fire Protection Functional Inspection procedure.

i The Commissioners s In July 1996, the staff issued NUREG-1552, " Fire Barrier Penetration Seals in Nuclear Power Plants," which documented its technical assessment of Senetration seals.

As airesult of recent Congressional inquiries, the staff 7as initiated an assessment of seal problems reported since it )erformed the assessment discussed in thss.NUREG report.

The staff will use tie insights from this effort to determine. if additional NRC or industry actions on fire barrier penetration seals is needed. This effort is not a part of the FP-TAP but is being tracking by the staff in a separate mini action alan.
