SUBJECT:
LASALLE COUNTY STATION, UNITS 1 AND 2 - CORRECTION LETTER FOR LICENSE AMENDMENT NOS. 195 AND 182, RE: REVISE LOCAL POWER RANGE MONITOR CALIBRATION FREQUENCY (TAC NOS. MD9414 AND MD9415)
Dear Mr. Pardee:
By letter dated September 16, 2009 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML092440755), the Nuclear Regulatory Commission (NRC) staff issued Amendment Nos. 195 and 182 to Facility Operating License Nos. NPF-11 and NPF-18 for the LaSalle County Station, Units 1 and 2, respectively. The amendments are in response to your application dated July 25,2008 (ADAMS Accession No. ML082110187), as supplemented by letters dated October 31, 2008 (ADAMS Accession No. ML083080059), February 17, 2009 (ADAMS Accession No. ML090480372), May 8,2009 (ADAMS Accession No. ML092380433) and July 27,2009 (ADAMS Accession No. ML092100162).
An administrative error was identified in the amendments. On Technical Specification (TS) page 3.3.1.3-3, Surveillance Requirement (SR) 3.3.1.3.5 should state U< 60% of rated recirculation drive flow." This SR was not part of the changes for this amendment request.
Please replace TS page 3.3.1.3-3 with the enclosed copy.
The incorrect information was editorial in nature. The corrections do not change the approval conveyed by the amendments, or the conclusions reached by the associated safety evaluation.
We regret any inconvenience this may have caused you.
Sincerely, Cameron S. Goodwin, Project Manager Plant Licensing Branch 111-2 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-373 and 50-374
