NUCLEAR PLANT NO. 2, OPERATING LICENSE NPF-21 WNP-2 EgUIPHENT SETPOINT HETHODOLOGY PROGRAM PLAN

Reference:

Letter, G02-90-029, GC Sorensen (SS) to JB Hartin (NRC),

same subject, dated February 20, 1990 In the reference letter the Supply System committed to. provide a new schedule for both the harsh environment accuracy effects- as well as the overall equipment setpoint methodology program plan within 30 days. This revised schedule was required because of the delays in executing the contract with Bechtel and mob'lizing qualified personnel to do the work. The purpose of this" letter is to rovide our revi sed schedule.

The'etpoint program design team for FY90 is on site, trained, and began work on t)is effort March 12, 1990. Additionally, the methodology has been revised to iqcorporate the latest ISA standard draft (December 1989) and the Supply System is presently completing efforts with Bechtel Corporation to computerize the setpoint calculation effort. These additional efforts have resulted in the attached schedule which does not limit the original harsh environment schedule slip to 60 days as had been expected. The Supply System is considering the possibility of adding additional resources in order to increase our confidence that the new schedule will be maintained.

Pyge Two WNP-2 EQUIPMENT SETPOINT

.HETHODOLOGY PROGRAM PLAN As shown by 'the attached schedule, inclusion of harsh environment accuracy utilizing recent ISA standard methodology has first priority in the overall program. This effort will require recalculation of setpoints (instrumentation and electrical equipment) for approximately 240 equipment pieces. Retrieval of applicable design basis information for this equipment is underway and the magnitude of the effort can only be estimated at this time. Until such time that we can quantify the data retrieval effort based upon actual experience the harsh environment schedule has been extended to account for this potential difficulty.

The Supply System is working very diligently to attempt to meet the attached schedules. These schedules are based on best estimates and are predicated on availability of data. In some cases, completion of the scheduled work may result in the initiation of new work, making it very difficult to say with absolute certainty that the scheduled date of October 31, 1990 for 100% completion of harsh environment setpoint work can be maintained.

The Supply System will advise you as to any concerns with the schedule viability as the magnitude of the program becomes quantifiable through actual experience.

Very truly yours, G. C. Sorensen, Manager Regulatory Programs HLA/bk Attachment cc: NS Reynolds - BCP8R RB Samworth - NRC DL Williams - BPA Document Control Desk - NRC NRC Site Inspector - 901A
