Metropolitan Edison Company (Met-Ed)

Three Mile Island nuclear Generating Station Unit 1 (TMI-1)

Docket No. 50-289 Operating License No. DPR-50 Technical Snecification Change Recuest No. 35 Page 3-21, rechnical Specification 3.3.1.1.a: Delete "The manual valve on the discharge of the BWST shall be locked open."

Reason for Pronosed Change Technical Specification 3.3 1.1.a is confusing because there are no manual valves on the discharge of the BWST. This proposed change vill remove any ambiguity that may exist due to the present Technical Specification.

This proposed change was recommended by the Region I NRC compliance inspector, Mr. Lee Spessard.

Safety Analysis Justifying Chance The proposed change does not alter the design capabilities of the emergency core cooling injection system. The preposed change does not involve an unreviewed safety question, nor does this change cause any undue risk to the health and safety of the public.

Cost-Benefit Analysis Justifying Chance There is no significant cost involved in this change.
