Acceptance Review for TACs MF5133 & MF5134 - Limerick Units 1 and 2 -
Add New LCOs 3.0.5 and 3.0.6 Stephanie, By letter dated November 3, 2014 (ADAMS Accession No. ML14308A144), Exelon Generation Company, LLC submitted a license amendment request for Limerick Generating Station (LGS),
Units 1 and 2. The proposed amendment would add new Limiting Conditions for Operation (LCOs) 3.0.5 and 3.0.6 to the Applicability Section of the LGS Technical Specifications (TSs).
LCO 3.0.5 establishes the allowance for restoring equipment to service under administrative controls when it has been removed from service or declared inoperable to comply with TS Action requirements. LCO 3.0.6 provides appropriate actions to be taken when the inoperability of a support system results in the inoperability of related supported systems. In addition, the proposed changes involve adding new Safety Function Determination Program (SFDP) requirements to the Administrative Section of the TSs to ensure that a loss of safety function is detected and appropriate actions are taken when LCO 3.0.6 is entered.
The purpose of this e-mail is to provide the results of the NRC staffs acceptance review of this amendment 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 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), an amendment to the license (including the TSs) must fully describe the changes requested, and following as far as applicable, the form prescribed for original applications. Section 50.34 of 10 CFR addresses the content of technical information required. This section stipulates that the submittal address the design and operating characteristics, unusual or novel design features, and principal safety considerations.
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 proposed amendment request 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. You will be advised of any further information needed to support the NRC staffs detailed technical review by separate correspondence.
