Request 2012-001 The SSES Units 1 and 2 third 10-year 1ST interval began on June 1, 2004. The applicable Code of Record for SSES Units 1 and 2 is the ASME OM Code, 1998 Edition through 2000 Addenda. This Code requires, in part, that valves in the scope of the 1ST Program as specified in 1100(a) shall be tested in accordance with the applicable requirements of Subsection ISTC. For check valves, as an alternative to the testing requirements of ISTC, ISTC-S222 allows the owner to implement a check valve condition monitoring program in accordance with the requirements of Mandatory Appendix II. The requirements of Mandatory Appendix II may be applied to any valve or group of valves up to and including the entire 1ST Program check valve population.
Any valves not included in the condition monitoring program are required to be tested in accordance with the applicable Subsection ISTC requirements.
In addition, the following requirements must be complied with by owners choosing to use Mandatory Appendix II of the 1998 Edition of OM Code: (1) Paragraph 10 CFR SO.SSa(b)(3)(iv)(A):
Valve opening and closing functions must be demonstrated when flow testing or examination methods (nonintrusive, or disassembly and inspection) are used. (2) Paragraph 10 CFR SO.SSa(b)(3)(iv)(B):
The initial interval for tests and associated examinations may not exceed two fuel cycles or 3 years, whichever is longer; any extension of this interval may not exceed one fuel cycle per extension with the maximum interval not to exceed 10 years; trending and evaluation of existing data must be used to reduce or extend the time interval between tests. (3) Paragraph 10 CFR SO.SSa(b){3){iv)(D):
The applicable provisions of subsection ISTC must be implemented if the Appendix II condition monitoring program is discontinued.
The licensee requested approval to use the corresponding portions of the 2004 Edition of the ASME OM Code through 2006 Addenda related to establishment of a check valve condition monitoring program. These portions include: Subsection ISTA which specifies general requirements for the 1ST Program including the scope of components to be tested;
-3 ISTC-S222 which allows the owner to implement at his discretion a check valve condition monitoring program in accordance with the requirements of Mandatory Appendix II; and Mandatory Appendix II which specifies the requirements for implementation of a check valve condition monitoring program. Unlike the version of Mandatory Appendix II contained in the 1998 Edition of OM Code, the version contained in the 2004 Edition of OM Code has no further requirements specified by 10 CFR SO.SSa(b)(3)(iv), as all of the previously specified requirements were subsequently incorporated into the later Code. The licensee proposes to apply the requirements noted above, to selected check valves in the scope of the SSES 1ST Program. A list of check valves selected for the condition monitoring program will be maintained in the respective Unit 1 or Unit 21ST Program Plans. Federal Register Notice dated June 21, 2011 (76 FR 36232), incorporated the 2004 Edition of ASME OM Code including Addenda through 2006, by reference in 10 CFR SO.SSa(b), subject to the limitations and modifications imposed by 10 CFR SO.SSa(b)(3).
Regulations in 10 CFR SO.SSa(b)(3) do not impose any additional limitations or modifications on the use of Mandatory Appendix II and the related requirements of Subsection ISTC. Note: Regulation in paragraph 10 CFR SO.SSa(b)(3)(i) does impose a limitation related to quality assurance as specified by OM Code Subsection 1ST A. However, this limitation is applicable to all licensees and all OM Code editions and is not specifically related to the implementation of a check valve condition monitoring program. 3.2 NRC Staff Evaluation The licensee has requested approval to apply the requirements of Subsection 1ST A (in its entirety), paragraph ISTC-S222, and Mandatory Appendix II (in its entirety) of the 2004 Edition of ASME OM Code through 2006 Addenda to selected check valves in the SSES 1ST Program. These requirements will be used for various check valves at SSES, in lieu of the corresponding requirements of the 1998 Edition of ASME OM Code through 2000 Addenda. The NRC staff has determined that there are no further limitations or modifications imposed by 10 CFR SO.SSa(b)(3) on the use of these portions of the 2004 Edition of the ASME OM Code through 2006 Addenda. Additionally, the NRC staff has not identified any additional related requirements in the 2004 Edition of the OM Code through 2006 Addenda that need to be met in order to implement the requested portions.
Therefore, use of Subsection ISTA (in its entirety), paragraph ISTC-S222, and Mandatory Appendix II (in its entirety) from the 2004 Edition of the ASME OM Code through 2006 Addenda for selected check valves at SSES Units 1 and 2, is acceptable.
4.0 CONCLUSION
As set forth above, the NRC staff determines that the licensee's request to apply the requirements of Subsection ISTA (in its entirety), paragraph ISTC-S222, and Mandatory Appendix II (in its entirety), using the 2004 Edition of ASME OM Code through 2006 Addenda for various check valves in the SSES 1ST Program, for the remainder of the third 10-year 1ST interval, is acceptable.
These requirements will be used for check valves at SSES Units 1 and 2, in lieu of the corresponding requirements in the 1998 Edition of ASME OM Code through 2000 Addenda. Accordingly, the NRC staff concludes that the licensee has adequately addressed all of the regulatory requirements set forth in 10 CFR SO.SSa(f)(4)(iv), and is in compliance with the ASME OM Code requirements.
All other ASME OM Code requirements for which relief was not specifically requested and approved remain applicable.
Therefore, the NRC staff authorizes this request for the remainder of the Third 10-Year Interval for the 1ST Program which began on June 1,2004, and is scheduled to end on May 31,2014, at the SSES, Units 1 and 2, subject to the limitations and modifications listed in 10 CFR SO.SSa(b).
