SUBJECT:
STRUCTURAL INTEGRITY OF CONTROL ROD DRIVE MECHANISM PENETRATION NOZZLES NO. 23 AND 63 -
OCONEE NUCLEAR STATION UNIT 2 (TAC No.
M95291)
Dear Mr. Hampton:
On April 9-11, 1996, the Duke Power Company (DPC) performed re-inspections of the No. 23 and No. 63 Control Rod Drive Mechanism (CRDM) penetration nozzles at the Oconee Nuclear Station (ONS) Unit 2. The re-inspections were part of your routine refueling activities for the Unit 2 End-of-Cycle 15 (spring 1996) refueling outage.
By letter dated April 30, 1996, DPC submitted a safety assessment (flaw evaluation) of these nozzles. This evaluation was supplemented with additional information by letters dated May 22 and October 9, 1996.
The staff has reviewed your assessment of the penetration nozzles, as outlined in the enclosed safety evaluation. This evaluation is based, in part, on observations of the staff who were present for the CRDM penetration nozzle examinations in April 1996, as well as on your flaw evaluation submittals.
Based on our review of this information, the staff has concluded that the flaw indications in No. 23 and No. 63 CRDM penetration nozzles will be acceptable for service over the next two operating cycles for plant operation; i.e.,
operation of the ONS Unit 2 plant for operating cycles 16 and 17.
Sincerely, Original signed by:
