REQUEST FOR ADDITIONAL INFORMATION RELIEF REQUEST C-3 LUMINANT GENERATION COMPANY LLC COMANCHE PEAK NUCLEAR POWER PLANT, UNIT 2 DOCKET NO. 50-446 By letter dated October 31, 2013 (Agencywide Documents Access and Management Systems (ADAMS) Accession No. ML13312A121), Luminant Generation Company LLC (Luminant, the licensee) submitted for the U.S. Nuclear Regulatory Commission (NRC) approval relief request (RR) C-3. The licensee proposed an alternative to a certain requirement of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code),Section XI.
RR C-3 relates to the inservice inspection (ISI) requirement of IWC-5220 of the ASME Code,Section XI, for the system leakage test of the reactor pressure vessel (RPV) flange leak-off piping. The licensee submitted the request for the Comanche Peak Nuclear Power Plant (CPNPP), Unit 2.
The NRC staff requests the following additional follow-up information.
- 1. Section 5 Burden Caused by Compliance and Section 6 Proposed Alternative and Basis for Use of Attachment 1 of RR C-3 stated, in part, Therefore, compliance with the IWC-5220 system leakage test requirements results in an unnecessary hardship without a sufficient compensating increase in the level of quality and safety.
In lieu of the requirements of IWC-5220, a VT-2 visual examination of the accessible areas will be performed each period on the piping subjected to the static pressure head when the reactor cavity is filled. This test will be part of the reactor coolant Class 2 leakage test.
The NRC staff notes that the ASME Code,Section XI, IWC-5220 System Leakage Testing includes two sub-articles, IWC-5221 Pressure and IWC-5222 Boundaries.
(a) Please clarify whether the proposed system leakage test was submitted as an alternative to address only the pressure requirement as specified in IWC-5221. (b) IWC-5222(a) and (b) require specific pressure boundaries for the system pressure tests. The NRC staff notes that the licensees submittal did not address the requirements of IWC-5222(a) and (b). If IWC-5222(a) and IWC-5222 (b) are also the subject of this RR, please discuss the hardship caused by compliance with IWC-5222(a) and IWC-5222(b),
and provide corresponding alternatives.
- 2. Please discuss leakage detection capabilities at the plant, and or any measure(s) taken, to monitor and identify leakage in an unlikely event of a through wall leak in the RPV flange seal leak-off line piping concurrent with leak or failure of the RPV flange inner seal during normal operation.
