Loomis:
By letter dated August 7, 2009, Exelon Generation Company, LLC, submitted a request for approval to use specific provision from a later Edition of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) for the subject units. The proposed approval would allow the subject units to use IWA-2221(c), Magnetic Particle Examination, and IWA-222(b), Liquid Penetrant Examination, of the ASME Code,Section XI, 2004 Edition.
The Inservice Inspection programs for the subject units are based on the 2001 Edition though the 2003 Addenda of the ASME Code.
The purpose of this email is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff=s acceptance review of this approval request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.
Consistent with Section 50.55a(g)(4)(iv) of Title 10 of the Code of Federal Regulations, inservice examination of components and system pressure tests may meet the requirements set forth in subsequent editions and addenda that are incorporated by reference in paragraph (b) of Section 50.55a, subject to the limitations and modifications listed in paragraph (b) of this section, and subject to Commission approval. Portions of editions or addenda may be used provided that all related requirements of the respective editions or addenda are met.
The NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the request in terms of regulatory requirements and the protection of public health and safety and the environment. If additional information is needed for the staff to complete its technical review, you will be advised by separate correspondence.
If you have any questions, please contact me at (301) 415-1055.
