UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 May 27, 2014 Karen D. Fili Site Vice President Monticello Nuclear Generating Plant Northern States Power Company - Minnesota 2807 West County Road 75 Monticello, MN 55362-9637

SUBJECT:

MONTICELLO NUCLEAR GENERATING PLANT- CORRECTION LETTER FOR AMENDMENT NO. 180 TO RENEWED FACILITY OPERATING LICENSE RE:

MAXIMUM EXTENDED LOAD LINE LIMIT PLUS (MELLLA+) (TAC NO. ME3145)

Dear Mrs. Fili:

On March 28, 2014, the U.S. Nuclear Regulatory Commission (NRC) issued Amendment No. 180 to Renewed Facility Operating License No. DPR-22 for the Monticello Nuclear Generating Plant (Agencywide Documents Access and Management System (ADAMS)

Package Accession No. ML14070A042).

On May 19, 2014, the NRC staff was informed by a member of your staff that an error had been identified on Technical Specification (TS) Table 3.3.1.1-1, "Reactor Protection System Instrumentation," Function 2.f., "OPRM Upscale," of the issued amendment. Specifically, in its MELLLA+ application dated January 21, 2012 (ADAMS Accession No. ML100280558),

Northern States Power Company requested that the Allowable Value be changed from "As specified in COLR" to "NA", consistent with Section 8 of approved topical report General Electric Nuclear Energy NEDC-33075P-A, Revision 6, "Detect and Suppress Solution -Confirmation Density Licensing Topical Report," dated January 2008 (ADAMS Accession Package No.

ML080310384). In the approved License Amendment No. 180, the Allowable Value of "NA" was inadvertently omitted from Function 2.f of Table 3.3.1.1-1 on TS page 3.3.1.1-8.

The NRC staff concludes that the error was introduced during preparation of the license amendment and is entirely editorial in nature. The proposed correction does not change any of the conclusions in the safety evaluation associated with the amendment and does not affect the associated notice to the public. Please find enclosed the replacement page.

K. Fili If you have any questions regarding this matter, please call me at (301) 415-3049.

Sincerely,

~ Terry A. Beltz, Senior Project Manager Plant Licensing Branch 111-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket No. 50-263

(e) Following DSS-CD implementation, DSS-CD is not required to be armed while in the DSS-CD Armed Region during the first reactor startup and during the first controlled shutdown that passes completely through the DSS-CD Armed Region. However, DSS-CD is considered OPERABLE and shall be maintained OPERABLE and capable of automatically arming for operation at recirculation drive flow rates above the DSS-CD Armed Region.

(f) If the as-found channel setpoint is not the Nominal Trip Setpoint but is conservative with respect to the Allowable Value, then the channel shall be evaluated to verify that it is functioning as required before returning the channel to service.

(g) The instrument channel setpoint shall be reset to the Nominal Trip Setpoint (NTSP) at the completion of the surveillance; otherwise, the channel shall be declared inoperable. The NTSP and the methodology used to determine the NTSP are specified in the Technical Requirements Manual.
