Dear Sir:

Three Mile Island :iuclear Statica Unit 1 (TMI-1)

Docket No. 50-289 Operating License No. EPR-50 IE Eulletin 76-07 Met-Ed has not =ade nor do we plan to make any modifications to the hoist, controls for the installed cranes at TMI-l si=ilar to tnose described in your IE bulletin 76-07. Although no such modifications have been made, the main hoist en the Reactor Building Crane has two motors and therefore does have a bre.e contactor. Therefore, prior to the next Reacter Head Re= oval, Met-Ed vill:

1.

Verify that the brake centactor is rated for h80V AC and is sized for the current drawn by the brake.

2.

Inspect the brake contactor for the Reactor Building Crane main hoist.

Sincerely, R. C.
