Dear Sir:

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

Operating License No. DPR-50 Docket No. 50-289 GPUN Response to Generic Letter (GL) 89-21

" Request for Information Concerning Status of Implementation of Unresolved Safety Issue (USI) Requirements" Pursuant to Generic Letter 89-21, please find attached the tabular information for TMI-1 Unreviewed Safety Issues (USI) as requested in Enclosure 1 to the Generic Letter. The status is based on our understanding of the issues as described in the Generic Letter and on discussions with and information provided by NRC Project Manager Ron Hernan.

The information in the remarks column provide the basis for our understanding of the implementation status. Projected implementation dates do not represent a change to commitments previously provided by GPUN, and, however, are subject to modification. In addition, the resolution of certain USIs (e.g., A-11, A-26, and A-49) may require re-evaluation as a result of conditions which change with operation over plant life. j Sincere ',
