SUBJECT:

UNIMPLEMENTED GENERIC SAFETY ISSUES AT THREE MILE ISLAND UNIT 1 (TAC NO. 7599*)

On April 25, 1990 the staff issued Generic Letter 90-04 which requested infor-mation concerning the implementation status of certain generic safety issues >

(GSis) at your facility. Based on your response to this Generic Letter, dated June 18, 1990, our own records and discussions with your staff, we have updated our database on GSI implementation status. The results of this effort were presented to the Comission at a meeting on October 25, 1990.

The enclosure to this letter sumarizes the staff's understanding of the current status of those GSIs which remain unimplemented at TMI-1. We appreciate the assistance you provided in responding to Generic Letter 90-04 and we encourage your timely completion of those GS1s listed in the enclosure.

Please contact me if you have any questions or comments about the enclosed information.

Sincerely, Ronald W. Hernan, Senior Project Manager Project Directorate 1-4 Division of Reactor Projects - 1/11 Office of Nucicar Reactor Regulation
