Acceptance Review - Relief Request NDE-SG-PZR-IRS, Relief from Requirements of American Society of Mechanical Engineers Boiler and Pressure Vessel Code,Section XI Examination Requirements (EPID L-2018-LLR-0138)

By letter dated November 7, 2018 (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML18311A391), Pacific Gas and Electric Company submitted relief request NDE-SG-PZR-IRS for Diablo Canyon Nuclear Power Plant, Units 1 and 2 (DCPP) for fourth inservice inspection interval. The request is associated with the hardship of applying the American Society of Mechanical Engineers Boiler and Pressure Vessel Code,Section XI, examination requirements for the inside radius sections of Code Class 1 pressure retaining nozzles in the steam generators and pressurizer at DCPP.

The NRC staff has reviewed your application and concluded that 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 in terms of regulatory requirements and the protection of public health and safety and the environment. 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. If additional information is needed, you will be advised by separate correspondence.

Based on the information provided in your submittal, the NRC staff has estimated that this licensing request will take approximately 160 hours6.667 days <br />0.952 weeks <br />0.219 months <br /> to complete. The NRC staff expects to complete its review and formal authorization by July 31, 2019. If there are emergent complexities or challenges in our review that would cause changes to the initial forecasted completion date or significant changes in the forecasted hours, the reasons for the changes, along with the new estimates, will be communicated during the routine interactions with the assigned project manager.
