10CFR50.49 Environmental Qualification of Post Accident Monitoring Equipment

Dear Mr. Johnson:

This letter is to advise you of our efforts to environmentally qualify certain Post Accident Monitoring (PAM) equipment as required by 10CFR50.49 paragraph b(3). PSC had previously made a commitment, in our May 17, 1983 letter (Ref. 1, above), to have all PAM equipment qualified by December 31, 1984. That date was based on the submittal of a Reg. Guide 1.97 report to the NRC by August 31, 1984.

In our March 9, 1984 letter (Ref. 2), PSC informed the NRC that, due to delays in the NRC on-site Safety Parameter Display System (SPDS) pre-implementation review, we could not protide a RG 1.97 reoort by August 31, 1984. Consequently, the submittal date for the report was revised to February 28, 1985.

We have just compiled a preliminary list of our PAM parameters.

Although a review of this preliminary list indicates that our existing PAM instrumentation is qualified, we will be unable to establish full qualification until our final list is prepared.

P-84527 Page 2 i.,

Therefore, we wish to revise our PAM equipment qualification schedule as follows:

l l

1)

Equipment identified in our RG 1.97 report, that currently exists in harsh environments, will be qualified by March 31, 1985, as required by 10CFR50.49 paragraph g.

I 2)'

Equipment required for Post Accident Monitoring that does not presently exist, will be qualified in accordance with 10CFR50.49, as it applies to an HTGR, prior to its installation at FSV.

If any questions concerning this matter should arise, please contact Mr. J. R. Reesy at (303) 571-8406.

Very truly yours, hhh i
