Dear Mr. Stolz:

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

Operating License No. DPR-50 Docket No. 50-289 Natural Circulation Cooldown (GL 81-21)

This revised analysis was performed as a result of modifications to the TMI-1 HEATING 6 model. The existing natural circulation cooldown procedure (0P-1102-16) has been modified pursuant to 10 CFR 50.59 to incorporate these results.

Sincerely, 1
