Ms. Simpson, By letter dated September 5, 2013, Exelon Generation Company, LLC, submitted license amendment request (LAR) for LaSalle County Station, Units 1 and 2 (ADAMS Accession No. ML13249A231). The LAR proposes to revise the LaSalle Technical Specifications (TS) 5.5.13, "Primary Containment Leakage Rate Testing Program," to increase the peak calculated primary containment internal pressure for the design basis loss of coolant accident, Pa.

The purpose of this message is to provide the results of the Nuclear Regulatory Commission (NRC) staff's acceptance review of this LAR. 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.

Section 50.34 of 10 CFR addresses the content of technical information required.

The NRC staff has reviewed your application and has concluded that it provides technical information in sufficient detail to enable the NRC staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendments in terms of regulatory requirements and the protection of public health and safety and the environment. If additional information is needed for the NRC staff to complete its technical review, you will be advised by separate correspondence.
