UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 2055&0001 December 5,
1994 Dr. Robert C. Hecredy Vice President, Nuclear Production Rochester Gas and Electric Corporation 89 East Avenue Rochester, NY 14649 SUBJECT'EQUEST FOR ADDITIONAL INFORHATION (RAI) REGARDING GENERIC LETTER 93-04, "ROD CONTROL SYSTEH FAILURE AND WITHDRAWAL OF ROD CLUSTER CONTROL ASSEHBLIES, 10 CFR 50.54(f)" TAC NO. H86848
Dear Dr. Hecredy:
By letters dated August 5 and September 20,
- 1993, you responded to Generic Letter (GL) 93-04.
In your response, you discussed the possibility of conducting a new current order surveillance test and a current order timing modification.
The staff, by letter dated November 10, 1994, to the Westinghouse Owners Group (WOG), approved the following documents:
(1) WCAP-13864, Rev.
1, "Rod 7 Control System Evaluation Program,"
(2) Westinghouse Technical Bulletin NSD-TB-94-05-RO, "Rod Control CRDH Timing Change,"
and (3)
"WOG Recommended Rod Control System Surveillance Test."
The current order timing modification does not affect normal rod motion, but prevents asymmetric rod withdrawal should a Salem-type failure occur.
This modification was successfully tested at the Ginna Station on April 15, 1994.
The new current order surveillance test (to be done each refueling outage) verifies that no failures exist in the Rod Control System current order circuits.
The staff finds that the WOG's
- response, as discussed in the above Westinghouse documents, is an acceptable long-term resolution to GL 93-04.
The staff requests that you confirm that the current order timing modification and the new current order surveillance test (to be done each refueling outage),
as described in the above Westinghouse documents, have been implemented.
We request your response within 30 days from receipt of this letter.
The information collection contained in this request is covered by the Office bf Management and Budget clearance number 3150-0011, which expires July 31, 1997.

- needed, and completing and reviewing the collection of information.
