Result of the Acceptance Review by the NRC Staff for Request for Alternative VRR-ANO2-2009-1 (TAC No. ME2407)

Reference:

Request for Alternative, VRR-ANO2-2009-1, for the Fourth 10-Year Inservice Testing Interval.

TAC No.: ME2407 Dave and Bob:

By letter dated October 16, 2009, Entergy Operations, Inc. (Entergy, the licensee), proposed an alternative to the inservice testing (IST) requirements of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code),Section XI, pertaining to the frequency of the leak rate test for two service water boundary isolation valves at Arkansas Nuclear One, Unit 2 (ANO-2) for the fourth 10-year interval and intervals into extended plant life.

The code of record governing the fourth 10-year Inservice Testing (IST) interval for valves at ANO-2, is the ASME OM Code, 2004 Edition. The 2004 Edition of the OM Code Section ISTC-3630(a) requires that Category A valves, with a leakage requirement not based on an Owners 10 CFR 50, Appendix J program, shall be tested to verify their seat leakages are within acceptable limits and that the tests shall be conducted at least once every 2 years. The proposed test frequency is to perform the test at least once every 3 years for these valves. This request impacts only these two valves and would allow ANO-2 to test one valve per refueling outage instead of both valves in the same outage.

The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this relief request.

The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

Pursuant to Sections 50.55a(a)(3)(i) of Title 10 of the Code of Federal Regulations (10 CFR),

the applicant shall demonstrate that the proposed alternatives would provide an acceptable level of quality and safety. The NRC staff has reviewed your application and concludes that it does provide technical information in sufficient detail to enable the staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the request for alternative in terms of regulatory requirements and the protection of public health and safety and the environment. If additional information is needed for the staff to complete its technical review, you will be advised by separate correspondence.

If you have any questions, please contact me at (301) 415-1480.
