SUBJECT: NRC INTEGRATED INSPECTION REPORT NO. 50-289/99-07

Dear Mr. Langenbach:

On August 28,1999, the NRC completed an inspection at your Three Mile Island Unit i reactor

facility. The enclosed report presents the results of that inspection which the resident inspectors

discussed with you and your staff during the September 8,1999 exit meeting.

1

Your staff continued to operate the unit safely, conducting observed operations, maintenance, j

engineering, and plant support activities well. Outage preparations proceeded acceptably.  :

Corrective actions planned to address the continuous failures of engineered safeguards relays I

to reposition following actuation were appropriate based on the determined root cause. I

Operator actions for such a degraded relay during this period were acceptable, however the

initial operability evaluation was based solely on prior experience with these relays and did not

use further testing as a means to verify operability. Engineering took appropriate actions to

address surveillance testing vibration issues on the A decay heat removal pump.

In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter and its

enclosures will be placed in the NRC Public Document Room (PDR).

No reply to this letter is necessary. We appreciate your cooperation.

Sincerely,

1
