Subject:

Kewaunee - Draft RAI on proposed Alternative No. RR-1-11 (TAC ME1394)

Jack:

The NRC staff has reviewed the information provided by Dominion Energy Kewaunee for Kewaunee Power Station in its letter dated May 28, 2009, and has determined that additional information, as set forth below, is necessary to complete the review of RR-1-11.

10 CFR 50.55a(g)(6)(ii)(E) states in part, All licensees of pressurized water reactors shall augment their inservice inspection program by implementing the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) Case N-722 subject to the conditions specified in paragraphs (g)(6)(ii)(E) (2) through (4) of this section. Note (4) to ASME Code Case N-722, Table 1, Item B15.80 requires that, Personnel performing the VE shall be qualified as VT-2 visual examiners and shall have completed a minimum of four (4) hours of additional training in detection of borated water leakage from Alloy 600/82/182 components and the resulting boric acid corrosion of adjacent ferritic steel components.

The second paragraph on page 6 of the submittal states: The examiners that performed the RPV BMI penetration examinations during the 2008 refueling outage held current VT-1, VT-2 (non-alternative) and VT-3 qualifications. Each of the examiners successfully completed Boric Acid Corrosion Control (BACC) Inspector Training. In addition to BACC training, each of the examiners was required to review EPRI Technical Report 1006296 (reference 6). Completion of these training activities have been determined to be equivalent to the four (4) hours of additional training cited in Code Case N-722.

1. Provide more specific details of the training that the visual examiners received in detection of borated water leakage from Alloy 600/82/182 components.

2. Detail the number of hours each inspector completed in training to recognize borated water leakage and also detail how these hours were documented.

3. Provide a reference for the Boric Acid Corrosion Control Program.

Please set up a conference call with me to discuss the following draft RAI questions. The sole purpose of this e-mail is to prepare you and others for the requested conference call.

This e-mail does not formally request for additional information, and does not convey an official NRC staff position.
