• 80 Park Place Newark, N.J. 07101 Phone 201 /622-7000 Mr. Bernard C. Rusche, Director Office of Nuclear Reactor Regulation

u. s. Nuclear Regulatory Commission Washington, D. c. 20555 Attention: Mr. Karl Kniel, Chief Light Water Reactors Branch No. 2

Dear Mr. Rusche:

REACTOR VESSEL OVERPRESSURIZATIONS Public Service Electric and Gas Company was requested by your letter dated August 27, 1976 to evaluate system designs to determine susceptibility to overpressurization events and to notify you within 20 days that we will provide all the informa-tion requested within 60 days or explain why we cannot meet this schedule and provide the schedule that will be met.

This letter is to notify you that a task group of utilities with Westinghouse plants has been formed, of which PSE&G is a participant, to examine the complexity of the overpressurization events and to identify similarities between Westinghouse plants for the purpose of determining a consistent solution to this issue. The task group will meet with Westinghouse .for the pur-pose of establishing plant groupings and to evaluate the means by which the likelihood of* additional occurrences of reactor vessel overpressurization events can be minimized.

Each utility will examine their plant's operating procedures and administrative controls during the 60-day period referenced in your August 27, .1976 letter. The purpose of this examination will be to evaluate procedural changes that will minimize the likelihood of overpressurization events. As an interim measure, the plant operating personnel have been informed of the potential for overpressurization and cautioned to minimize conditions which could cause such an event should reduced pressure and temperature operation occur before the detailed review is comple,ted.

• 9-15-76 The results of the task group meetings as applicable to Salem and other investigations performed by PSE&G, will be reported to you at the end of the.60-day period. Recommendations and schedules will be given at that time as well as the results of the plant procedure review and resulting procedure revisions, if appropriate.

Should you have any questions concerning this program, please contact the undersigned.

Sincerely yours,
