| Title | Licensee-Identified Violation |
| Description | 10 CFR 50.55a (f), Inservice Testing Requirements, in paragraph (4) requires, in part, that throughout the service life of a nuclear facility, pumps and valves which are classified as American Society of Mechanical Engineers (ASME) Code Class 1, Class 2, and Class 3 must meet the inservice test requirements set forth in the ASME OM Code. Contrary to this, on August 15, 2007, the licensee determined Pressurizer (PZR) Safety Valves were not being tested at the 60 month test frequency required by the Code. The licensee was measuring the 60 month test frequency from the time the valve was installed to next test date, as opposed to the Code-required frequency of test date-to-test date. This finding is determined to be of very low safety significance because the test history and reliability of the PZR safety valves shows these valves routinely meet the test acceptance criteria and the licensees risk analysis performed on the extended surveillance showed the Incremental Conditional Core Damage Probability (ICCDP) is less than 1.0E-06 and the Incremental Conditional Large Early Release Probability (ICLERP) is less than 1.0E-07. The licensee entered the finding into their CAP as CR 2007108020. On Unit 1, PZR safety valves outside of the 60 month testing frequency were removed and forwarded to vendor for testing. On Unit 2, one valve is currently installed but will be removed during the next refueling outage scheduled for October 2008 |
