I. BACKGROUND On June 9, 1985, the Davis-Bessa Nuclear Power Station experi-enced a loss-of-main-feedwater transient. A number of equipment i

failures and an operator error occurred which resulted in a temporary loss of all feedwater flow. Feedwater flow was recovered through manual initiation of the startup feedwater pump I and the auxiliary feedwater system. The plant was subsequently i brought to a cold shutdown condition. The number of equipment I

~

failures which occurred during the June 9th event dictated the l

' need for a thorough investigation by Toledo Edison into the causes of the failures and completion of the corrective actions necessary to prevent recurrence of such events at Davis-Besse.

On September 12, the B&W Owners Group Executive Committee decided on a course of action in response to the Davis-Besse June 9 event to achieve the following objectives.

o Improve the safety and availability of the B&W units through close evaluation and implementation of lessons learned from'the June 9 event.

o Establish a mechanism to ensure strong communication between all of the B&WOG utilities regarding the issues and concerns identified during the review of the Davis-Besse transient.

o Establish an executive level forum to identify, track, and ensure completion of plant specific and generic

! recommendations that result from the review of the Javis-Besse transient.

o Maintain a proactive relationship with the NRC.

To achieve the first three objectives, the B&WOG Executive Committee directed the Chairman of the B&WOG Steering Committee l

! 1

to form a special Task Force. The Task Force was to be com-prised of representatives from each of the operating plants with a mission to thoroughly review the results of the investigation by Toledo Edison and the NRC to determine if any of the issues raised are applicable to the other B&W plants.

The fourth objective, " Maintain a proactive relationship with the NRC," is'being implemented as follows:

1 '

l. B&WOG meeting with NRC to discuss actions

! being planned as a result of the Ju'ne 9 Davis-Besse transient........... Completed November 5, 1985

2. Provide a copy of the "B&WOG Action Plan for the Review of the June 9, 1985 Davis-Besse transient................ Scheduled for December 1985

3. Status / review meeting with the NRC to report of implementation by the B&WOG of the Action Plan.....................................TBD

4. Provide results of B&WOG efforts to the NRC...... July 1986 II. 1154 TASK FORCE COURSE OF ACTION A. Overview Consistent with the direction provided by the B&WOG Execu-tive Committee, the B&WOG 1154 Task Force was formed and held its organizational meeting on September 25-26, 1985, in Toledo, Ohio. At this meeting a draft version of the action l plan was developed.

The second meeting of the 1154 Task' Force was held in l St. Petersburg, Florida on October 30 and 31, 1985. The l second draft of the action plan was completed at this time.

1 The finalized version of the B&WOG Action Plan was completed at 1154 Task Force meeting #3 in Atlanta, Georgia on November 14 and 15, 1985.

i The B&WOG 1154 Task Force is being chaired by J. P. Moore of GPUN with S. J. McWilliams of AP&L serving as vice-chair-man. The total membership of the Task Force is as follows:

S. J. McWilliams - AP&L R. B. Thornton - AP&L W. L. Garrison - AP&L N. A. Rutherford - DPCo G. Ridgeway - DPCo J. R. Kraiker - FPC A. Friend - FPC E. E. Welsh - FPC J. P. Moore - GPUN P. Oubre' - SMUD W. C. Rowles - TED L. Grime - TED

. R. A. Turner - B&W The Task Force membership is comprised of representatives from each of the utilities with operating plants. Those utilities currently in the process of obtaining an operating license will address the Davis-Besse June 9 event later.

The above individuals were charged with the responsibility to develop an overall action plan for the B&WOG to coor-dinate these actions related to the Davis-Besse event within their individual utilities, and to provide the results to other members of the Task Force. They will also participate in the development and implementation of any generic activities that are identified for action and resolution by l

I the 1154 Task Force.

B. Detailed Course of Action

1. Introduction I Documents reviewed by'the Task Force to determine the

issues and concerns were o [[letter

:IA-85-445, Responds to FOIA Request for Vol III of Evaluation of Transient Behavior & Small RCS Breaks in 177 Fuel Assembly Plant, Re Facility.Document Available in PDR for Insp|August 5, 1985 letter]] from Mr. Dircks (including NUREG-ll54) describing actions related to Davis-Besse

o Toledo Edison's report entitled " Davis-Besse -

I Course of Action," Vols. 1 and 2, dated September 10, 1985 o August 14,-1985 letter from Mr. Denton to Mr. Joe Williams, Jr.

Four action levels were~used to categorize each of the resultant issues or concerns.

1. No Action Needed by B&WOG Members -

issue is Davis-Besse event applicable only.

4

2. Communication Amone B&WOG Members -

issue is j

generic to other plants and B&WOG will stimulate communication on key aspects and solutions to the j issue.

3. B&WOG Monitor and Document Resolution of Issue -

the issue will be reviewed and resolved by individual' utilities, and the B&WOG will monitor the status of implementation of the resolution, document the implementation, and report on j completion.

4. B&WOG ResDonsible for Resolution -

an entity

, within the Task Force or other B&WOG Committees

4 1

will be responsible for generically resolving the issue and reporting to the member utilities the recommendations as a result of this effort.

The action plan contained in Appendix A of this report was developed by the 1154 Task Force and is intended to address generic and plant specific hardware issues as well as the management and programmatic concerns that have been raised during the investigation of the Davis-Besse Event.

During the review of the two volumes of the Davis-Besse Course of Action, several items were evaluated by the 1154 l

l Task Force as being specific to Davis-Besse and therefore

~ they have not been specifically included in the B&WOG Action Plan. Much of the material in Volume 1 is dedicated to the formulation of the Davis-Besse Action Plan and includes

descriptive material of-how Toledo Edison intends to' fold l activities already underway into their Course of Action.

Items such as the PEP and SALP programs are integrated in their overall corrective action' plan. These programs are quite plant specific. In Volume 2, the sections describing the Toledo Edison Organization are, of course, not addressed in the B&WOG 1154' Task Force Action Plan. Likewise, the analysis of the failure of specific feedwater valve SP.74 is not included in the B&WOG Action Plan.

All'other B&W plant generic issues and programmatic concerns in-the Davis-Besse Course of Action plan, in Mr. Dirck's

! letter of August 5, 1985, and in Mr. Denton's letter of August 14, 1985 are addressed by the B&WOG 1154 Task Force Action plan.

1 l 2. Action Plan The action plan of the Task Force. presently contains 14~

separate items. Additional action items may be developed as 5

the review progresses and additional information is devel-oped. A separate action plan sheet has been provided by l each of the items in Appendix A. The following information is included for each sheet:

Responsibility Scheduled Completion Date Status / Comments Section References The responsibility designation is.used to indicate whether i the Task Force, other B&WOG Committees, or individual utilities are responsible for the resolution of the working plan action item. for items that. identify utilit r action for resolution, a letter report is requested from each -

utility under the Status / Comments heading. The content and

format of these reports is described in Appendix B to this report. The purpose of the references. noted at the bottom of the action items sheet is to identify and cross reference which issues contained in the various Toledo Edison and NRC reports are being addressed by a particular Task Force Action Item.

IV. CONCLUSIONS The B&W Owners Group has concluded that the Action Plan developed by the 1154 Task Force and presented in this report clearly demonstrates a proactive and aggressive approach aimed at enhancing the safety and availability of the B&W operating units.

It is further concluded that the implementation of this action plan will substantially reduce the likelihood that an event similar to the one that occurred at Davis-Besse on June 9, 1985, will not occur at another B&W unit.
