Finding

Title

LICENSEE-IDENTIFIED Violation

Description

The following violations of very low safety significance (Green) or Severity Level IV were identified by the licensee and are violations of NRC requirements which meet the criteria of the NRC Enforcement Policy, for being dispositioned as a Non-Cited Violation.Title 10 CFR 50.55a(f), Inservice testing requirements, subsection (4) required, in part, that pumps and valves which are classified as ASME Class 1, Class 2, and Class 3 must meet the inservice test requirements set forth in the ASME OM Code. The ASME Code of record for Vogtle for Operation and Maintenance of Nuclear Power Plants (OM) is the 2004 edition through 2006 addendum. Subsection ISTC-1300, Valve Categories, required in part, that valves within this subsection shall be placed in one or more of the following categories. Category A is for valves for which seat leakage is limited to a specific maximum amount in the closed position for fulfillment of their required function(s), as specified in ISTA-1100. Contrary to the above, since 1991, the licensee did not categorize valves in ECCS recirculation flow paths to the RWST as Category A valves to ensure the ASME OM test requirements were met by leak testing the valves to demonstrate that their seat leakage would limit the consequences of an accident to control room operators and to the public at the site boundary per Title 10 CFR Part 100 limits. The inspectors determined this finding was of very low safety significance (Green) because the issue would only have the potential to represent a degradation of the radiological barrier function provided for the control room. This issue was documented in the licensees CAP as CR 829367 and TE 886122.
