Dear Sir:
Three Mile Island IIuclear Station Unit 1 (TMI-1)
Docket llc. 50-289 Ope.ating License EPR-50 As a result of the RCS cverpressurization analys's forwarded with cur letter G@ 0322 of . arch a2,1977, Met-Ed proposes the follcwing action:
1.
cdification of tr' e Ilitrogen Systen to provide backup relier capability to prevent RC3 cverpressurization.
"his is necessary due to the use of a supplementary nitrogen supply.
2.
Initiation of administrative centrola prohibiting the use of supplementarf nitrogen supplies capable of overpressu izing the RC3 whenever the pilct actuated relief valve is isciated.
"nis action vill be seneduled for cc=platicn pricr t:; the Cycle k refueling cutage. :Ic further modifications or administrative centrals are deered ne ce s sarf.
Sincerely,
