S. Nuclear Reactor Regulation Washington, DC 20555 Docket No. 50-267

Subject:

IE Bulletin 80-06

Reference:

P-82054

Dear Mr. Kuzmycz:

Per the meeting held in Denver between yourself and Messrs. Reesy, Niehoff, and Pitchkolan of my staff, this letter provides you with our position in regards to IE Bulletin 80-06.

It is Public Service Company's (PSC) positica that the verbal NRC Requests for additional testing of the Fort St.

Vrain Plant Protective System (PPS) are unwarranted for the following reasons:

i l

1.

The circui try associated with PPS actuations, trips and resets has been thoroughly analyzed and no problems were identi fied.

2.

NRC's I&E branch has reviewed the information and test results provided by our letter P-82054, and indicated in their letter of May 6,1982 that all questions raised by the i

bulletin were resolved.

t 3.

To accomplish such testing, the Fort St. Vrain plant would f

have to be repeatedly tripped from a power operating level.

There are approximately 50 separate trip signals involved I

thus, testing the entire PPS as requested would repeatedly subject the plant to severe transients. We feel that this

/ [

presents an undo risk to the plant and plant personnel.

8206030065 820528 PDR ADOCK 05000267 l

G PDR

P-82168 Paga 2 May 28, 1982 4.

The circuitry of the PPS is continually surveillance tested.

This testing is covered by Section 5 of the Technical Specifications.

5.

The Fort St.

Vrain Station has experienced nmuerous transients over the years. - During these transients there has never been a case identified where the actuation signal reset and prohibited a required trip.

If you have any questions please call Jack Reesy at (303) 571-6643.

Very truly yours,
