Dear Mr. Pacilio:

By application to the U.S. Nuclear Regulatory Commission (NRC) dated December 20, 2013 (Agencywide Documents Access and Management System Accession No. ML13358A354),

Exelon Generation Company, LLC submitted a license amendment request (LAR) to revise the reactor coolant system pressure and temperature curves for LaSalle County Station, Unit 1.

The application also included an affidavit dated April 5, 2013, executed by Linda C. Dolan of GE-Hitachi Nuclear Energy Americas LLC (GEH) requesting that some information contained in of the LAR be withheld from public disclosure pursuant to Title 10 of the Code of Federal Regulations Part 2, Section 2.390.

The NRC staff is reviewing the GEH request to withhold information from public disclosure and has determined that it needs additional information to complete its review. A response to the enclosed Request for Additional Information is requested by September 12, 2014. If it is determined that some of the information requested to be withheld can be made publicly available, then provide a revised public version

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

Sincerely, Blake Purnell, Project Manager Plant Licensing 111-2 and Planning and Analysis Branch Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation

REQUEST FOR ADDITIONAL INFORMATION REQUEST FOR WITHHOLDING INFORMATION IN LICENSE AMENDMENT REQUEST TO REVISE PRESSURE AND TEMPERATURE LIMIT CURVES LASALLE COUNTY STATION. UNIT 1 DOCKET NO. 50-373 By application to the U.S. Nuclear Regulatory Commission (NRC) dated December 20, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13358A354), Exelon Generation Company, LLC (Exelon) submitted a license amendment request (LAR) to revise the reactor coolant system (RCS) pressure and temperature (Pff) curves, Figures 3.4.11-1 through 3.4.11-3 of technical specification (TS) 3.4.11, "RCS Pressure and Temperature (Pff) Limits," for LaSalle County Station (LSCS),

Unit 1. The application included an affidavit dated April 5, 2013, executed by Linda C. Dolan of GE-Hitachi Nuclear Energy Americas LLC (GEH) requesting that some information contained in of the LAR be withheld from public disclosure pursuant to Title 10 of the Code of Federal Regulations Part 2, Section 2.390.

The NRC staff is reviewing the GEH request to withhold information from public disclosure and has determined that it needs additional information to complete its review. If it is determined that some of the information requested to be withheld can be made publicly available, then provide a revised public version.

By email dated January 31, 2011 (ADAMS Accession No. ML110310390), NRC staff issued a request for additional information (RAI) to Grand Gulf Nuclear Station, Unit 1 (GGNS), regarding its Pff limits. As noted in Exelon's application, the staff has requested that future applicants for Pff limit changes include a response to this GGNS RAI. In Attachment 6 of the application, Exelon provided the LSCS, Unit 1, response to this GGNS RAI.

The NRC staff notes that information provided for GGNS RAI 9, which GEH has requested to be withheld from the public, appears to be publicly available in a nonproprietary version of GE Nuclear Energy report GE-NE-0000-0003-5526-02R1, "Pressure-Temperature Curves for Exelon LaSalle Unit 1," Revision 1, dated May 2004. This GE Nuclear Energy report was included as Attachment 6 to an April 19, 2010, application from Exelon and is publicly available in ADAMS under Accession No. ML101130377.

Provide a response to the following:

a. Explain how GEH has held the information in confidence when GEH has previously indicated that the information was nonproprietary and it has been made publicly available.

b. Explain how this is a type of information normally held in confidence when GEH has previously indicated that the information was nonproprietary.

c. Explain how release of this information would cause substantial harm to GEH when GEH has previously indicated that the information was nonproprietary and it has been made publicly available.

Some of the information provided for GGNS RAI #7 which GEH has requested to be withheld from the public appears to be information which is included in the proposed TS 3.4.11. The proposed TS 3.4.11, which was included with the application, was not identified as containing proprietary information and has been made publicly available in ADAMS.

Regarding the information provided in response to GGNS RAI #7 that GEH has requested to be withheld from the public, provide a response to the following:

a. Identify any proprietary information which is included in the proposed TS 3.4.11. Explain how this is a type of proprietary information normally held in confidence when it is to be included as part of the technical specifications. Explain how release of this information would cause substantial harm to GEH when it has been made publicly available as part of the application.

b. Identify any proprietary information that could be derived from information in TS 3.4.11 using publicly available information. Estimate the effort and money to derive such information and explain how release of this information would cause substantial harm to GEH.
