' James T. Wiggins, MAP Chairman SUlUPLT: NINTH MAP MEETING HELD ON MARCH 2,1993 4

The ninth Millstone Assessment Panel (MAP) meeting was held in Region i from 2:30 p.m. -

4:30 p.m.. The attendecs at the meeting were:

Panel Memben:

Randolph Blough, Chief, DRP Dranch 4 Larry Doerflein, Chief, DRP Section 4A Dave Jaffe, Project Manager, NRR John Stolz, Director, Projects Directorate 1-4 Paul Swetland, Senior Resident inspector, Millstone James Wiggins, Deputy Director, DRP Other Attendees:

Richard Barkley, Project Engineer, DRP Section 4A Robert De la Espirella, Reactor Engineer, DRP Section 4A Plant Status:

The meeting started with a discussion by Paul Swetland of the statur of each of the Millstone Units. Curr.:ntly, Unit 1 is operating at 100% power. Since the last MAP meeting, NU l

l requested and was granted a temporary waiver of compliance and a license amendment to bypass the main steam line radiation monitors while placing a demineralizer back in service. NU is also taking corrective actions in response to the fallere of a circuit breaker that contributed to a plant transient last month. The cause of the failure was a misalignment of the breaker that was attributed to poor maintenance. Unit 2 operated at 100% power until late February when the plant tripped :wice on low steam generator level. 'Ihe first trip occurred when the positioner linkage on an atmospheric dump valve broke, causing the valve to open and eventually resulting in a plant transient that led to a reactor trip on low steam generator level. The second trip l

occurred after excessive turbine vibration was experienced. While removing the turbine generator from service, the operators were unable to control the resulting feedwater system perturbation and again tripped the plant on low ste.m generator level. The root causes of these l two trips are being reviewed, but part of the problem may be due to the different performance characteristics of the new st::am generators.

r . MAP Minutes #9 , 2  ! Unit 3 has been operating at 100% power following the repair of the motor <lriven pump that was out of service lei January. 'N'I identified a problem with the surveillance interval.for the 

                      . . snubbu testing program; a TS waiver of compliance and an emergency TS change were issued
to allow the' surveillance interval to be extended on a one-time-only basis In addition,.the < ~

resident inspectors recently identified a concern described in a recent LER with overlap testing ' of TS required instrumentation systems. The event indicated that NU had pursued a narrowly _ focused. series of corrective actions for previously identified problems in this area. . , I Sv=ad of the MAP We wEh NU on Ja==a-v 13. 1993: The results of that meeting were provided by letter to NU on February 8,1993. De meeting was informative and appropriately focused toward the MAP's concerns. He MAP needs to continue to ensure that the outstanding public meeting comments discussed at that meeting are  ; addressed by the NRC. { Action: Walt Paselak to ensure that DRSS-EP addagssed the emergency preparedness concerns raised at the November 5,1993, public meeting (Pasclak - 4/15/93)} Pan =rattaae ==d L haduta for the Futum C-=l=laa Mamelas: 9 The MAP discussed the proposed schedule for the meeting with NU and the Commission. The date of that meeting has been repeatedly postponed and will probably not be scheduled until after the Harassment and Intimidation enforcement issue is resolved. However, given that the MAP's determination of the adequacy of the PEP verification and validation (V&V) issue may be a long while off, the meeting with the Commission should not be delayed because the MAP's review l of the PEP V&V. is not yet completed.. Caraniants on the PEP Review T*=== Renort/ Status of the SER ortjbe PEP: t The second draft of the report of the PEP Review Team was provided to the MAP members for their review and comment following the last MAP meeting. Dat report will lar$ orm the - baals for the SER on the PEP. Based on the potential long delay in completing ttwEP report 

                           -due to the need to rereview the verification and validation effort, the MAP decided to push issuing the PEP report in the near future with three open items: 1) the acceptance of the
      '..           .-      verification and validation effort,. 2) a further. cvaluation of employee commitment .to the -                                                             %         .

program and 3) how NU evaluates the adequacy and comprehensiveness of the PEP based on operating experience and inspection findings. He MAP instructed Rich Barkley to work with Dave Jaffe to finalize the PEP report in tht near future. 

                           ' { Action: Rich Barkley to issue a final version of the PEP Team Report and put it la the concurrence chain (Barkley - 3/23/93)}
