FACILITY: Palisades Nuclear Plant

SUBJECT:

SUMMARY

OF JUNE 22,2010, PRE-APPLICATION MEETING WITH ENTERGY NUCLEAR OPERATIONS, INC., TO DISCUSS PRESSURIZED THERMAL SHOCK ANALYSIS (TAC NO. ME4021)

On June 22, 2010, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Entergy Nuclear Operations, Inc. (ENO), at NRC Headquarters, One White Flint North, 11555 Rockville Pike, Rockville, Maryland. The purpose of the meeting was to discuss the Pressurized Thermal Shock (PTS) issue for the Palisades Nuclear Plant (PNP) reactor pressure vessel (RPV). A list of attendees is provided as .

Prior to the meeting, the licensee had submitted "Documentation for Pressurized Thermal Shock Evaluation Meeting," dated June 2010 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML101540386). During the meeting, the licensee's presentation provided overview of the PTS issue at Palisades. The licensee discussed with the NRC staff the historical status, future plans and the proposed timeline for future actions regarding the Palisades RPV PTS issue (ADAMS Accession No. ML101740061).

The licensee plans to submit a complete PTS re-assessment in accordance with Title 10 of the Code of Federal Regulations (10 CFR) Section 50.61, "Fracture toughness requirements for protection against pressurized thermal shock events," utilizing new and pertinent data presented during this meeting and to validate the date of March 2014 for current PNP RPV heat-up and cool down curves. The licensee also plans to initiate activities relative to performing an evaluation of the PNP RPV utilizing 10 CFR 50.61a, "Alternate fracture toughness requirements for protection against pressurized thermal shock events," prior to performing in-service inspection of PNP RPV in the spring of 2012. The NRC staff found the licensee's future actions to be reasonable, however, they also recommended that the licensee have contingency plans in place until meeting the PTS regulatory requirements. The licensee adequately responded to staff questions and provided the necessary information and clarifications. There was also a general consensus to conduct additional meetings or teleconferences as needed.
