SUBJECT:
Limerick Generating Station Docket Nos. 50-352 and 50-353 Process Computer Preoperational Tests REF:
J. S. Kemper to A. Schwencer letter dated July 17, 1984 FILE:
GOVT l-1 (NRC)
Dear Mr. Schwencer:
In the reference letter, PECo requested approval to defer the completion of certain Preoperational Tests until after fuel load. After closer examination of the content and purpose of Preoperational Test P31.1, Process Computer System, we have concluded that these testing activities we,uld be properly classified as part of our Acceptance Test program.
We therefore intend to modify Tables 14.2-1 and 14.2-4 of the FSAR to delete P31.'1 from the Preoperational Test Program.
It should he noted that the P31.1 test procedures will be used to conduct all of the computer Acceptance Tests.
The substance of this
-change in test classification.is that.he test results will be reviewed by the cognizant.PECo computer engineer and the Plant Operations Review
-Committee in lieu of the Preoperational Test Review Board.
All portions of the coug:ter system which are nosociated with monitoring reactivity control systams will be tested and verified operational prior to fuel load.
The Rod Worth Minimizer program is tested as part _of Preoperational Test PS6.lB to satisfy Regulatory Guide 1.68, App.
A, Section 1.b. (1).
The core performance software will _ be tested during_ the Power Ascension Program by test STP-13 in accordance with Regulatory Guide 1.68, App. A, Section 5.r.

'We believe that the testing program described above for the Process Computer meets and exceeds all-regulatory requirements and that it will allow confinnation of the proper. operation of the Process Computer in a timely manner.
The attached draft FSAR page changes.will be incorporated into the PSAR, exactly as they appear in the attachments, in the revision scheduled Lfor October, 1984.'
Sincerely, SWf EFS/la.
