Dear Sir:

Three Mile Island Nuclear Station, Unit 1 (TMI-1)

Operating License No. DPR-50 Docket No. 50-289 Technical Specification Change Request No. Th requested an amendment to the Tech. Specs. per the Co= mission's letter dated 11/7/77 The Cor:: mission reviewed this T.S.C.R. and proposed the following hardware changes as part of the change request:

1. Alarm MU-V16A/B/C/D to signal when they are not seated and the RCS temperature is less than 275 0F.
2. Install pressure / temperature recorders, the pressure recorders must be capable of recording 100 psi /see pressure changes.
3. Install a pressure alarm to indicate that the RCS pressure has exceeded h85 psig.

We have reviewed these proposed hardware changes and will include these in the modifications which will be made to Unit 1, prior to startup.

Sincerely,
