Dear Mr. Lear:

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

Docket No. 50-289 Operating License No. DPR-50 In our letter (GQL 0954) of April 19, 1975, we stated that we would submit (1) A schedule for the completion of equipment modifications necessary to provide an/ alternate flow path so as to assure that boron pre-cipitation would not compromise long-tern core cooling capability following a loss-of-coolant accident (IDCA), and (2) Appropriate abstracts of associated procedures or procedure re-visions.
