Dear Mr. Jurgensen:
18,1981 (CE-54), you su=arized a meetinc In your letter dated Marchbetween representatives of the t;RC staff, held on February 20, 1981 Tne purocse Westinghouse C"aners, and Westingnouse Electric Corocration.
of tne meeting' was to discuss the Westingneuse Craners Group.(WO3) activities in response to t?UREG-0737, Clarification of TMI Action Plan Re:uirements. Item I.C.1, Guidance for the Evaluation and Develop-Foli wing the mening ment of Procedures for Transients and Accidents. summary tne program described in the meeting.
As indicated in a meeting witn Tem Anderson, of Westinghcuse, on April 1931, we nave concerns about tne acceptaoiiity of the WOG Ina:ect. ate C re Cooiing Guidelines, recuired tne coerator program.
Subse:uent failures were, essentially, adcressed oy entry in::

guidelines co not adcress suosecuent reevaluation of plant condi icns to ensure that tne expected plant resconse is occurring.
Our second concern is your proposec schedule for comole:ing the program recocnizing that development of emergency operating crocedures is aHowev cynamic process with no aosolute end point.
that continual, major rewriting of emergency coerating procedures is a burden on plant operating staffs and confusing to tne ocerators who In the February meeting, WOG representa-must reiearn the procedures.
tives indicated thay tney expect to have the initial deveicoment chase of tne guidelines cor.aleted in July 1931, and would not ex:ect major cnanges.o tne guidelines to resuit f r:m tne tuses te be ccn:leted in You also sta:e in your iet.er that tne January 1932 and July 1982.adcress over 95 cer:ent of tne total risk.

Inerefore, we cannot assess tne overall adequacy of the proo sed Uniess our concerns, as stated herein, are satisfied, the program.
ability of licensees to meet the schedule for revising their procedures may ce ccmcromisec.
As indicated in tne April 8,1981 meeting, we nave serious coubts that tne full range of initiating events and suosecuent failures can ce adcressed within the event soecific f ramework adooted by tne Westing-house Owners Grouo.
If your additional work to date crovices nore insight into. resolution of these concerns, we would be available to meet witn you at your convenience.
