Robert Kuntz Senior Project Manager NRC/NRR/DORL/LPL3 (301) 415-3733 DRAFT REQUEST FOR ADDITIONAL INFORMATION MONTICELLO NUCLEAR GENERATING PLANT ALTERNATIVE VR-08 EMIB-RAI-1:
Background:
Alternative Request VR-08 proposes that ASME OM Code Case OMN-28 be implemented in lieu of the requirements in ASME OM Code, Subsection ISTC, paragraph ISTC-3700, for the remote position verification of valves at Monticello.
Regulatory Requirements:
The NRC regulations in Section 55a, Codes and standards, in Part 50, Domestic Licensing of Production and Utilization Facilities, in Title 10, Energy, of the Code of Federal Regulations (10 CFR 50.55a) in paragraph (z), Alternatives to codes and standards requirements, state the following:
Alternatives to the requirements of paragraphs (b) through (h) of this section or portions thereof may be used when authorized by the Director, Office of Nuclear Reactor Regulation.
A proposed alternative must be submitted and authorized prior to implementation. The applicant or licensee must demonstrate that:
(1) Acceptable level of quality and safety. The proposed alternative would provide an acceptable level of quality and safety; or
(2) Hardship without a compensating increase in quality and safety. Compliance with the specified requirements of this section would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety.
Issue:
Note 1 to the tables in Alternative Request VR-08 states that OMN-28 may be applied to all valves in the IST program that meet OMN-28 requirements in the future.
Request:
In that the NRC is being requested to authorize an alternative under 10 CFR 50.55a(z) to allow components to deviate from the 10 CFR 50.55a regulatory requirements, please identify the specific components by their ID numbers within the scope of Note 1 in Alternative Request VR-
