Director THI-1

Middletown, Pennsylvania 17057

Gentlemen:

Subject: Inspection 50-289/85-22

During the period from September 16 to October 11, 1985, members of the NRC

THI-1 Restart Staff conducted routine and special safety inspections of

shutdown and operational activities at your facility. The results of these

inspections are documented in the enclosed inspection report. At the

conclusion of the inspection Mr. R. Conte, of my staff, summarized the

inspection findings for you and other members of your staff. The findings

were generally favorable.

A significant finding during this inspection period is that the two safety

valves on the steam supply line to the turbine-driven emergency feedwater pump

actuate on initiation of the EFW system. Our safety concern _is that one or

both of the safety valves could fail open when challenged, thereby causing the

EFW pump to become inoperable. We are satisfied with your interim corrective

action of providing guidance to the operators on what to do if a safety valve

should fail open. These actions, as described in your letter of October 11,

1985, to T. Murley, NRC, were verified during NRC Inspection No. 50-289/85-24.

We acknowledge your commitment to provide a final lorsg-term solution before

the startup to return to 100% power at the completior of your power escalation

program.

Also during the period, out inspectors identified one instance of your failing

to meet regulatory requirements as set forth in the enclosed Notice of

Violation (Appendix A). The violation resulted from workers failing to

properly store or remove equipment in a safety-related area, the radiator room

for the "A" emergency diesel generator. You should follow the instructions on

the attached Notice of Violation.

is appreciated.
