SUMMARY

OF MEETING HELD ON JULY 19, 1979, TO DISCUSS OUTSTANDING ITEMS FROM COMMISSION ORDERS AND IE BULLETINS GENERIC TO ALL BABCOCK & WILCOX (B&W) OPERATING PLANTS On July 19, 1979, members of the NRC staff were invited to attend a meeting of the B&W:Owners' Group (TMI-2 Follow-up Subcommittee) in Bethesda, Maryland to discuss outstanding items related to the Commission's confirmatory shutdown Orders issued for each B&W operating plant and Bulletins issued by the NRC's Office of Inspection and Enforcement (IE).

In addition to representatives from the NRC staff and the licensees listed above, representatives from B&W also participated in the meeting.

A list of attendees is provided as Enclosure 1 to this summary.

Background

In light of the Three Mile Island Unit 2 accident, the Commission confirmed by Orders, issued to each holder of an operating license for facilities using a B&W designed reactor, that each licensee would undertake a series of actions, both immediate and long-term, to increase the capability and reliability of the plant to-respond to various transient events. In addition, each Order confirmed that the facility would shut down or remain shut down and not be restarted until the immediate actions specified in the Order were accomplished and found acceptable by. the Director, Office of Nuclear Reactor Regulation. These immediate actions were completed by each licensee, reviewed by the NRC staff and found acceptable.

However,, in each staff Safety Evaluation of the licensee's compliance with the Commission Order, certain issues were found to require more detailed and long-term study prior to their final resolution. Several of these issues are applicable generically to all of the B&W operating plants.

In addition to the Commission Orders, a series of IE Bulletins were issued (79-05,79-05A and 79-05B) to each of the B&W operating plants. These Bulletins also required a series of actions to be taken by the licensees. Actions taken by the licensees, as a result of these Bulletins, are presently undergoing review by the NRC staff. Many of these specific actions are also applicable generically to all of the B&W operating plants.

Meeting Summary JUL J 1 979 The majorpurpose of the meeting was to discuss these generic issues with theB&W'Owners' Group to determine the feasibility of resolving some of these issues through the Owners' Group instead of through separate interaction with each licensee.

Discussion The NRC staff explained the respective roles of the special task forces which have been organized within the Office of Nuclear Reactor Regulation, subse quent to the TMI-2 accident. A detailed explanation of the Bulletins & Orders (B&O) Task Force was then presented. This included a breakdown of the work scope, interfacing organizations, organization within the Task Force, schedule of B&O activities with respect to the B&W facilities, and a review of the items considered by the staff as outstanding B&W generic issues. A copy of each of the viewgraphs presented by the staff is provided in Enclosure 2 to this summary.

Mr. David Holt (Duke Power Company), Chairman of the Subcommittee, then presented an overview of the membership, scope, objectives and organization of the B&W Owners' Group. Mr. Holt pointed out that the Owners' Group does not constitute a legal entity and'assumes no financial or legal responsibility for its members or.member companies. As such, all contractual matters and program funding are controlled by each member in accordance with individual contracts with B&W or other suppliers of services to the Owners:' Group.

The Qwners' Group cannot make any legal or commercial commitments for individual members.

As a result of this understanding, it was agreed between the Owners' Group and the staff that the Group could still be useful by providing a forum for joint discussions of generic issues and establishing unified positions during interactions with B&W and/or the NRC. However, correspondence requiring the expenditure of funds would not be addressed to the Owners' Group, but would be sent to each of the member licensees. A copy of the Owners' Group organization and charter is provided as Enclosure 3 to this summary.

The NRC staff then presented a detailed discussion of auxiliary feedwater system (AFW) reliability and performance. Upgrading the performance and reliability of the AFW system was required as an immediate action on all of the Commission's Orders issued to the B&W plants. It was pointed out that additional review and modifications would be required in this area in the future. The staff discussed its detailed review of the AFW systems installed in all of-the plants with Westinghouse and Combustion Engineering designed reactors. This review included obtaining a response to a staff questionnaire, and meeting with each licensee to review the "as built" design and operation of each AFW system. The information obtained for each plant was evaluated by

a systems engineer and a systems reliability engineer, with emphasis given to improving AFW system performance and reliability, including the identification of dominant failure modes and giving consideration to the potential for the human operators to affect the AFW system performance and reliability. The criteria' of the current issue of Standard Review Plan Section 10.4.9 and

JUL 3 1 979 Meeting Summary

-3 Branch Technical Position ASB 10-1 were also used in the evaluation.

It was pointed out that the objective of the short-term recommendations is to supplement IE Bulletin requirements for the Westinghouse and Combustion Engineering plants to quickly improve the AFW system performance and relia bility and the objective of the long-term recommendations is to end up with an AFW system that is adequate and answers all relevant TMI-2 concerns. The draft short-and long-term recommendations of this study were discussed with the Owners' Group. The staff evaluation of the Westinghouse and Combustion Engineering plants will be available as a NUREG document by the end of August 1979. It was suggested by the NRC staff and agreed to by the Owners' Group that they would perform a reliability study on their plants, using the same methodology as the staff used for the Westinghouse and Combustion Engineering plants. The Owners' Group committed to meeting with the staff in mid-August to outline their plan for performing this study. The study would serve as a basis for continued design modifications and/or improvements to upgrade the performance and reliability of the AFW system.

The staff closed the meeting with a review of the status of the following topics:

(1) IE Bulletin Review Draft Safety Evaluations have been prepared for responses to Bulletins 79-05. and 79-05A. Responses to Bulletin 79-05B are being reviewed and incorporated into these Safety Evaluations. A request for addi tional information will be sent to each licensee, where required, to, resolve any open items.

Issuance of the Safety Evaluations should take place in September 1979.

(2) Technical Specification Change Requests As a result of actions taken to comply with the Commission's Orders andIE Bulletins, each licensee has filed requests for changes to its facilities' Technical Specifications.

SUMMARY

OF MEETING HELD ON JULY 19, 1979, TO DISCUSS OUTSTANDING ITEMS FROM COMMISSION ORDERS AND IE BULLETINS GENERIC TO ALL BABCOCK & WILCOX (B&W) OPERATING PLANTS On July 19, 1979, members of the NRC staff were invited to attend a meeting of the B&WOwners' Group (TMI-2 Follow-up Subcommittee) in Bethesda, Maryland to discuss outstanding items related to the Commission's confirmatory shutdown Orders issued for each B&W operating plant and Bulletins issued by the NRC's Office of Inspection and Enforcement (IE).

In addition to representatives from the NRC staff and the licensees listed above, representatives from B&W also participated in the meeting.

A list of attendees is provided as Enclosure 1 to this summary.

Background

In light of the Three Mile Island Unit 2 accident, the Commission confirmed by Orders, issued to each holder of an operating license for facilities using a B&W designed reactor, that each licensee would undertake a series of actions, both immediate and long-term, to increase the capability and reliability of the plant to respond to various transient events. In addition, each Order confirmed that the facility would shut down or remain shut down and not be restarted until the immediate actions specified in the Order were accomplished and found acceptable by. the Director, Office of Nuclear Reactor Regulation. These immediate actions were completed by each licensee, reviewed by the NRC staff and found acceptable.

However, in each staff Safety Evaluation of the licensee's compliance with the Commission Order, certain issues were found to require more detailed and long-term study prior to their final resolution. Several of these issues are applicable generically to all of the B&W operating plants.

In addition to the Commission Orders, a series of IE Bulletins were issued (79-05,79-05A and 79-05B) to each of the B&W operating plants. These Bulletins also required a series of actions to be taken by the licensees. Actions taken by the licensees, as a result of these Bulletins, are.presently undergoing review by the NRC staff. Many of these specific actions are also applicable generically to all of the B&W operating plants.

Meeting Summary JUL 1 1979 The major~purpose of the meeting was to discuss these generic issues with theB&W Owners' Group to determine the feasibility of resolving some of these issues through the Owners' Group instead of through separate interaction with each licensee.

Discussion The NRC staff explained the respective roles of the special task forces which have been organized within the Office of Nuclear Reactor Regulation, subse quent to the TMI-2 accident. A detailed explanation of the Bulletins & Orders (B&O) Task Force was then presented. This included a breakdown of the work scope, interfacing organizations, organization within the Task Force, schedule of B&O activities with respect to the B&W facilities, and a review of the items considered by the staff as outstanding B&W generic issues. A copy of each of the viewgraphs presented by the staff is provided in Enclosure 2 to this summary.

Mr. David Holt (Duke Power Company), Chairman of the Subcommittee, then presented an overview of themembership, scope, objectives and organization of the B&W Owners' Group. Mr. Holt pointed out that the Owners' Group does not constitute a legal entity and'assumes no financial or legal responsibility for its members or member companies. As such, all contractual matters and program funding are controlled by each member in accordance with individual contracts with B&W or other suppliers of services to the Owners' Group. The Owners' Group cannot make any legal or commercial commitments for individual members. As a result of this understanding, it was agreed between the Owners' Group and the staff that the Group could still be useful by providing a forum for joint discussions of generic issues and establishing unified positions during interactions with B&W and/or the NRC. However, correspondence requiring the expenditure of funds would not be addressed to the Owners' Group, but would be sent to each of the member licensees. A copy of the Owners Group organization and charter is provided as Enclosure 3 to this summary.

The NRC staff then presented a detailed discussion of auxiliary feedwater system (AFW) reliability and performance. Upgrading the performance and reliability of the AFW system was required as an immediate action on all of the Commission's Orders issued to the B&W plants. It was pointed out that additional review and modifications would be required in this area in the future. The staff discussed its detailed review of the AFW systems installed in all of'the plants with Westinghouse and Combustion Engineering designed reactors. This review included obtaining a response to a staff questionnaire, and meeting with each licensee to review the "as built" design and operation of each AFW system. The information obtained for each plant was evaluated by a systems engineer and a systems reliability engineer, with emphasis given to improving AFW system performance and reliability, including the identification of dominant failure modes and giving consideration to the potential for the human.operators to affect the AFW system performance and reliability. The criteria of the current issue of Standard Review Plan Section 10.4.9 and

JUL 3 1 1979 Meeting Summary

-3 Branch Technical Position ASB 10-1 were also used in the evaluation. It was pointed out that the objective of the short-term recommendations is to supplement IE Bulletin requirements for the Westinghouse and Combustion Engineering plants to quickly improve the AFW system performance and relia bility and the objective of the long-term recommendations is to end up with an AFW system that is adequate and answers all relevant TMI-2 concerns. The draft short-and long-term recommendations of this study were discussed with the Owners' Group. The staff evaluation of the Westinghouse and Combustion Engineering plants will be available as a NUREG document by the end of August 1979. It was suggested by the NRC staff and agreed to by the Owners' Group that they would perform a reliability study on their plants, using the same methodology as the staff used for the Westinghouse and Combustion Engineering plants. The Owners' Group committed to meeting with the staff in mid-August to outline their plan for performing this study. The study would serve as a basis for continued design modifications and/or improvements to upgrade the performance and reliability of the AFW system.

The staff closed the meeting with a review of the status of the following topics:

(1) IE Bulletin Review Draft Safety Evaluations have been prepared for responses to Bulletins 79-05 and 79-05A. Responses to Bulletin 79-05B are being reviewed and incorporated into these Safety Evaluations. A request for addi tional information will be sent to each licensee, where required, to resolve any open items.. Issuance of the Safety Evaluations should take place in September 1979.

(2) Technical Specification Change Requests As a result of actions taken to comply with the Commission's Orders and IE Bulletins, each licensee has filed requests for changes to its facilities' Technical Specifications. These requests are being reviewed by the staff and should result in license amendments being issued to the utilities in late August or early September 1979.

(3) Long-Term Actions Required by Commission Orders As part of the requirements for lifting the Commission Order, each utility was directed to provide a schedule, within 30 days of the Order being lifted, which provides its schedule for the completion of the long-term requirements of the Order. The staff is presently reviewing the adequacy of the long-term schedules. If the schedules need to be modified, the staff will deal directly with the licensees.

(4) Implementation of Short-Term Recommendations of the TMI-2 Lessons Learned Task Force A meeting will be held on August 1, 1979, in Bethesda, Maryland to discuss this topic. Additional meeting information, such as time, place and agenda will be forthcoming.
