| Title | |
| Description | While reviewing the licensees evaluation of generic communication Information Notice (IN) 2014-02, Failure To Properly Pressure Test Reactor Vessel Flange Leak-Off Lines, the inspectors identified that the licensee had determined that the pressure testing requirements described in IN 2014-02, did not apply to the reactor vessel seal leak-off line because this line was not part of the reactor coolant pressure boundary and, therefore, the licensee continued to exclude this line from ASME pressure testing requirements for Code Class 2 components. IN 2014-02 states, in part, that 10 CFR 50.55a(g)(4) requires that ASME Code Class 1, 2, and 3 components (including supports) meet the requirements, except the design and access provisions and the preservice examination requirements, set forth in Section XI of the ASME Code, to the extent practical within the limitations of design, geometry, and materials of construction of the components. The ASME Code,Section XI, Tables IWB- 2500-1, IWC-2500-1, and IWD-2500-1 require that a system leakage test be conducted in accordance with IWB-5220, IWC-5220, and IWD-5220 for Class 1, 2, and 3 pressure retaining components, respectively. Subarticle IWA-5200 of Section XI of the ASME Code specifies the system test requirement for pressure-retaining components and states that the system leakage tests shall be conducted at the pressure and temperature for Class 1, Class 2, and Class 3 components specified in IWB-5000, IWC-5000, and IWD-5000, respectively. The inspectors determined that the licensee had never performed the ASME Code required system leakage test on the reactor vessel flange seal leak-off line. The licensee documented the inspectors concern in CR 2015-10559. The licensee is developing additional information to support its current position. This issue is a URI pending inspector review of the licensees additional information. |
