MILLSTONE POWER STATION UNITS 2 AND 3 LICENSE RENEWAL - COMMENTS ON THE SER WITH OPEN ITEMS In a letter dated February 24, 2005, the NRC provided Dominion Nuclear Connecticut, Inc. (DNC) the Safety Evaluation Report (SER) with Open Items for license renewal of Millstone Power Station, Units 2 and 3.

In the transmittal letter with the SER with Open Items, the NRC staff described their plans to review the format of the SER to further improve the content, while incorporating comments and responses. To that end, DNC has reviewed the SER with Open Items for consistency with the License Renewal Applications (LRAs),

LRA supplements, and subsequent information provided in response to NRC requests for additional information. Dominions comments are limited to items that, if not resolved for consistency with the License Renewal Applications, are considered to have implications on the bases of the conclusions presented in the SER.

Should you have any questions regarding this

Dominion did not convey information related to the below-grade environment at the time of construction for structures. Although changes at or near the site that could have affected the below-grade environment have not been identified, no groundwater chemistry evaluations were documented at the time of construction and such information was not provided to the NRC during audits with Millstone technical staff. However, groundwater testing is currently being performed and the results substantiate that the groundwater chemistry is within the limits identified in the GALL Report.

Delete the words, In the LRA, the applicant stated that the below-grade environment is not aggressive because the environment at the time of construction had a measured pH greater than 5.5, chlorides less than 500 ppm, and sulfates less than 1,500 ppm and subsequent testing has shown the environment has remained within these limits.

Groundwater test results at the time of construction were not provided in the LRA. Additionally, although changes at or near the site that could have affected the below-grade environment have not been identified, no groundwater chemistry evaluations were documented at the time of construction and such information was not provided to the NRC during audits with Millstone technical staff. However, groundwater testing is currently being performed and results substantiate that the groundwater chemistry is within the limits identified in the GALL Report.

Remove,...and excavated concrete has been and will continue to be monitored... from the 3rd paragraph since Dominion has not monitored excavated concrete in the past. Table A6.0-1, License Renewal Commitments, Item 21, identifies Enhancement 5 to the Structures Monitoring Program, which will ensure that inspections of inaccessible areas of below-grade concrete surfaces are performed when the areas become accessible by excavation or during maintenance or for any other reason.

Replace the commitment description in the Commitment column with:

Complete the SAMA evaluation of the ability to manually control the Turbine Driven Auxiliary Feedwater Pump. If this SAMA is cost beneficial (i.e., can be accomplished without a hardware modification), a Severe Accident Management Guideline (SAMG) addressing this mitigation strategy will be developed. With this change the SER will have the correct Unit 3 SAMA commitment instead of referencing the Unit 2 SAMA commitment in the Unit 3 table.
