SUMMARY

OF TELEPHONE CONFERENCE CALL BETWEEN DOMINION ENERGY KEWAUNEE, INC. AND THE U.S. NUCLEAR REGULATORY COMMISSION TO DISCUSS CERTAIN REQUEST FOR ADDITIONAL INFORMATION RESPONSES ON STRUCTURAL ITEMS (TAC NO. MD9408)

On January 21, 2010, the U.S. Nuclear Regulatory Commission (NRC or the staff) conducted a conference call (teleconference) with representatives from Dominion Energy Kewaunee, Inc.

(DEK). The purpose of the teleconference was to discuss certain DEK responses to the staffs requests for additional information (RAIs) regarding the Kewaunee Power Station (KPS)

Structural Monitoring Programs.

In a letter dated November 20, 2009 (Agencywide Documents and Access Management System

[ADAMS] Accession Number ML091890836), the staff submitted follow-up RAIs related to, among other items, the KPS Structures Monitoring Program (RAIs B2.1.31-3a, B2.1.31-4a, and B2.1.31-5a). DEK responded to the staffs RAIs by letter dated December 28, 2009 (ADAMS Accession Number ML100110061). During the teleconference, the staff indicated that the responses to the follow-up RAIs did not provide enough information for the staff to complete its evaluation. The main issues discussed during the teleconference are summarized below.

RAI B2.1.31-3a - Groundwater Quality:

The below-grade concrete at KPS has been exposed to chloride content above the GALL Report limit of 500 ppm, which means it has encountered an aggressive groundwater environment as defined in GALL (any of the following: pH < 5.5, or chlorides > 500 ppm, or sulfates > 1500 ppm). The probable cause of this is stated to be the use of salt for deicing, which began sometime between 1992 and 2000. Although the applicant states a new deicer will be used in the future, the staff needs assurance that the past exposure to an aggressive environment has not degraded the concrete.

The staff is looking for some sort of test or inspection that will provide assurance that the concrete is not degraded. The staff would also like to know what actions will be taken if in the future the chloride content in the groundwater does not drop below acceptable limits.

RAI B2.1.31-4a - Reactor Refueling Cavity Leakage:

The staff would like applicants plan (Commitment 33) to be submitted as part of the license renewal process, thus being a part of the current license renewal review. There are examples of such plans from recent license renewals of other facilities.

Dominion Energy Kewaunee, Inc.

The staff would like to see wording added (to an existing Commitment or as a new Commitment) that says a core will be taken in the refueling cavity if the spent fuel pool core indicates degradation.

RAI B2.1.31-5a - Spent Fuel Pool Leakage:

The staff would like the action plan (Commitment 35) to be submitted as part of the license renewal process, thus being a part of the current license renewal review.

The staff would like the core sample below the spent fuel pool (Commitment 34) to be taken as soon as practicable, allowing for planning and scheduling requirements of the activity. The applicant should explain why the decided upon schedule is appropriate (this can be included as part of the action plan mentioned in the above bullet).

As a result of the discussions, DEK indicated that they will supplement their responses to RAIs B2.1.31-3a, B2.1.31-4a, and B2.1.31-5a to provide additional information to the staff regarding the use and implementation of applicants Structures Monitoring Program. A list of teleconference participants is enclosed.
