Letter CNRO-2002-00043 from Entergy Operations, Inc. to the NRC, "Use of Mechanical Nozzle Seal Assemblies," dated August 5, 2002
Dear Sir or Madam:
In the referenced letter, Entergy Operations, Inc. (Entergy) submitted to the NRC staff a request (ANO1-R&R-002) to use the new design of the Mechanical Nozzle Seal Assembly (MNSA-2) in applications at Arkansas Nuclear One, Unit 1 (ANO-1). Entergy is submitting this follow-up letter in order to clarify the commitments pertaining to the use of the MNSA-2 device at ANO-1. These commitments are as follows:
- 1. Entergy agrees to visually inspect for leakage the counter-bore/annulus region of each installed MNSA-2 device during each refueling outage. Entergy agrees to perform this visual inspection and also, upon discovering leakage that occurred during the operating cycle, to remove the MNSA-2 and inspect it and the surrounding pressurizer surface for
-corrosion.
- 2. The use of the MNSA-2 covered by Request ANO2-R&R-002 will be limited to two (2) operating cycles of the current Inservice Inspection (ISI) interval for ANO-1, which ends on May 31, 2007.
- 3. Following NRC staff approval, Entergy will incorporate this alternative into the ANO-1 Inservice Inspection (ISI) Plan.
