SUBJECT:

LASALLE COUNTY STATION, UNIT 1 -ACCEPTANCE OF LICENSE AMENDMENT REQUEST TO REVISE PRESSURE AND TEMPERATURE LIMIT CURVES (TAC NOS. MF3270 AND MF3271)

Dear Mr. Pacilio:

By application 1 dated December 20, 2013, as supplemented by lette,-2 dated February 26, 2014, Exelon Generation Company, LLC (EGC) submitted a license amendment request to revise Technical Specification (TS) 3.4.11, "RCS [reactor coolant system] Pressure and Temperature (PIT) Limits," for LaSalle County Station, Unit 1. The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff's 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 (1 0 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, as supplemented, 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 amendment 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 staff's 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 staff's detailed technical review by separate correspondence.
