SUMMARY

OF SEPTEMBER 27,2012, PRE-APPLICATION MEETING TO DISCUSS THE DIESEL GENERATOR VOLTAGE AND FREQUENCY LIMITS LICENSE AMENDMENT REQUEST (TAC NOS. ME9468 AND ME9469)

On September 27,2012, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Northem States Power Company, a Minnesota corporation, doing business as Xcel Energy (NSPM, the licensee), at NRC Headquarters, One White Flint North, 11555 Rockville Pike, Rockville, Maryland.

The licensee's meeting slides can be found in ADAMS at Accession No. ML12275A378.

During the meeting the licensee discussed the applicability of Topical Report WCAP-17308, "Treatment of Diesel Generator (DG) Technical Specification Frequency and Voltage Tolerances." Additionally, the licensee discussed the proposed changes to the EDG surveillance requirements (SRs) and the technical bases for the changes. The proposed changes to the technical specification SR limits, discussed at the meeting, can be found in ADAMS at Accession No. ML12275A465.
