UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Mr. Michael J. Pacilio Senior Vice President Exelon Generation Company, LLC President and Chief Nuclear Officer Exelon Nuclear 4300 Winfield Road Warrenville, IL 60555 January 8, 2015

SUBJECT:

LASALLE COUNTY STATION, UNITS 1 AND 2-REQUEST TO WITHHOLD INFORMATION RELATED TO THE LICENSE AMENDMENT REQUEST TO REVISE THE ULTIMATE HEAT SINK TEMPERATURE LIMITS (TAC NOS.

ME9076 AND ME9077)

Dear Mr. Pacilio:

By application dated July 12, 2012 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML12200A330), Exelon Generation Company, LLC (EGC) submitted a license amendment request (LAR) for LaSalle County Station, Units 1 and 2, to revise Technical Specification 3.7.3, "Ultimate Heat Sink [UHS]." EGC provided supplemental information to the U.S. Nuclear Regulatory Commission (NRC) for the LAR by letter dated December 4, 2014 (ADAMS Accession No. ML14352A311). This letter included an affidavit dated November 4, 2014, executed by Thomas J. Behringer of Sargent & Lundy, LLC (S&L) requesting that the following document be withheld from public disclosure pursuant to Title 10 of the Code of Federal Regulations (1 0 CFR) Part 2, Section 2.390.

S&L MES-11.1, Revision 1A, "Effective Area of Cooling Lakes," dated November 3, 2014 The affidavit stated that the document listed above should be considered exempt from mandatory public disclosure for the following reasons:

i.

The documents are each either a policy, procedure, process, technical requirements document, or other document that forms part of the S&L Mechanical Engineering Guidelines ("MEG").

ii.

The MEG is a set of confidential guidelines used to assist in effectively and efficiently achieving the quality of work S&L produces to its clients.

iii.

The documents are now, and have been, held in confidence by S&L. S&L does not customarily make these documents available to the public. S&L has not authorized making the documents available through public sources.

iv.

S&L is providing the NRC with the documents and information in confidence.

v.

Economic harm would come to S&L with the publication of the individual documents that form the MEG, as it would reduce or eliminate the need for

third party to purchase or license the MEG from S&L, and would reduce the competitive position of S&L based on the benefits that the MEG provides to S&L in the execution of our business. The MEG is considered by S&L to be a very valuable part of our intellectual property and it would be very difficult, costly and time-consuming for another to duplicate it without access to these documents.

We have reviewed your application and the material in accordance with the requirements of 10 CFR 2.390 and, on the basis of the statements in the affidavit, have determined that the submitted information sought to be withheld contains proprietary commercial information and should be withheld from public disclosure. Therefore, the submitted document marked as proprietary will be withheld from public disclosure pursuant to 10 CFR 2.390(b)(5) and Section 1 03(b) of the Atomic Energy Act of 1954, as amended.

Withholding from public inspection shall not affect the right, if any, of persons properly and directly concerned to inspect the document. If the need arises, we may send copies of this information to our consultants working in this area. We will, of course, ensure that the consultants have signed the appropriate agreements for handling proprietary information.

If the basis for withholding this information from public inspection should change in the future such that the information could then be made available for public inspection, you should promptly notify the NRC. You also should understand that the NRC may have cause to review this determination in the future, for example, if the scope of a Freedom of Information Act request includes your information. In all review situations, if the NRC makes a determination adverse to the above, you will be notified in advance of any public disclosure.

If you have any questions regarding this matter, I may be reached at 301-415-1380.
