Subject:

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

Operating License No. DPR-50 Docket No. 50-289 Technical Specification Change Request (TSCR) No. 244 Cycle 10 Control Rod Trip Insertion Time Testing In accordance with 10 CFR 50.4(b)(1), enclosed is Technical Specification Change Request (TSCR) No. 244.

Also enclosed is a Certificate of Service for this request, certifying service to the chief executives of the township and county in which the facility is located, as well as the designated official of the. Commonwealth of' >

Pennsylvania, Bureau of Radiation Protection.

in accordance with the NRC Confirmatory Action Letter (CAL) of March 29, 1994, GPUN submitted evaluation criteria for control rod drop time testing results-by letter dated April 22, 1994. In our meeting with the staff on May-3, 1994, we were informed that NRC approval of the evaluation criteria was not likely to occur prior to scheduled drop time testing on June 1, 1994. In accordance with the April 22, 1994 letter, TSCR No. 244 requests a revised control rod trip insertion time testing acceptance criterion for the remainder of Cycle'10

.for the twelve (12) specific control rods which initially experienced slow rod drop times during. testing conducted on March 17, 1994.

In order to preclude the possible need for future Enforcement Discretion should control rod drop times for any of the specified control rods be greater than 1.66 seconds but less than 2.11' seconds, it is requested that this TSCR be processed under exigent procedtres to support continued TMI-l operation.
