Acceptance Review of Dresden Nuclear Power Station, Units 2 and 3, Relief Requests By letter dated September 28, 2012 (Agencywide Document Access and Management System (ADAMS)
Accession No. ML12275A069), Exelon Generation Company, LLC (EGC) submitted a relief request for Dresden Nuclear Power Station, Units 2 and 3. The proposed relief requests would authorize the actions listed in the table below:
Relief Request Summary of request Applicable 10 CFR 50.55a paragraph I5R-01 Perform a VT-2 visual exam of subject nozzles in conjunction w/
the system leak test as an alternative to ultrasonic exams 10CFR50.55a(g)(5)(iii)
I5R-03 Perform a VT-2 visual exam on the line during refueling outage as an alternative to failing an O-ring in a pneumatic test 10CFR50.55a(a)(3)(ii)
I5R-04 Perform a VT-2 visual exam of Isolation condenser and piping during TRM 5-yr operational test as an alternative to period requirements of Table IWD-2500-1.
I5R-05 Perform continuous pressure decay monitoring in conjunction with TS for nitrogen side of CRD accumulators as an alternative to VT-2 visual exam requirements 10CFR50.55a(a)(3)(i)
I5R-07 Use BWRVIP guideline requirements as an alternative to ASME Section XI code requirements 10CFR50.55a(a)(3)(i)
I5R-10 Proposes extending the applicability of ASME Code Case N-532-4 to the 2007 Edition through the 2008 Addenda from 2004 Edition through 2005 Addenda 10CFR50.55a(a)(3)(i)
I5R-11 Proposes extending the applicability of ASME Code Case N-661-1 to the 2007 Edition through the 2008 Addenda from 2004 Edition through 2005 Addenda 10CFR50.55a(a)(3)(i)
The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of these relief requests. 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
2 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.
Pursuant to Sections 50.55a(a)(3)(i), 10CFR50.55a(a)(3)(ii), and 10CFR50.55a(g)(5)(iii) of Title 10 of the Code of FederalRegulations (10 CFR), the applicant shall demonstrate that compliance with the specified requirements of Section 50.55a respectively, would provide an acceptable level of quality and safety, would result in hardship or unusual difficulty without a compensating increase in the level of quality or safety, or the requirement is deemed impractical.
The NRC staff has reviewed your application and concluded that for relief requests I5R-1, I5R-3, I5R-4, I5R-6, I5R-7, I5R-10, and I5R-11, it does provide technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed relief request in terms of regulatory requirements and the protection of public health and safety and the environment. Relief Request I5R-2 will be addressed by separate correspondence. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staffs ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. You will be advised of any further information needed to support the NRC staffs detailed technical review by separate correspondence.
If you have any questions, please contact me at (301) 415-6606.
