We have reviewed your 4/20/07 response and determined that we need additional information(see below) to complete our review. Consistent with our review process set forth in NRR Office Instruction LIC-101, Rev. 3, we would like to first discuss this information need with you in a conference call: (1)           The response to Request 2 states that out-of-tolerance is defined as "exceeding theband established around a desired value...."  However, the licensee has not defined how thisband is established. Provide the information about what uncertainties are included in the out-of-tolerance band, basis for their inclusion, and how it is calculated.(2)The response to Request 2 states that "An as-found condition that exceeds thecalibration tolerance......." However, the licensee has not defined how the calibration toleranceis determined. Provide the information about the uncertainties included in the calibration tolerance band, basis for their inclusion, and how it is calculated.(3)The response to Request 2, on page 3, first full paragraph provides the example of Unit1 calibration tolerance but did not state that the same value has been used for Unit 2 also and how it was determined. Provide the calibration tolerance band for Unit 2.   (4)The response to Request 2, on page 3, first full paragraph states that the"out-of-Tolerance" evaluation may include changes to the acceptance criteria, changes to switch design or calibration method (including the setpoint value), or the replacement of poorly performing components, but did not provide any detail on how it is determined and who makes that determination and how soon this evaluation is completed. Provide the missing information.This e-mail aims solely to prepare you and others for the proposed conference call.

D.C. Cook Unit 2 - Second Round of Draft RAI on the 9/15/06 Amendment Request (TAC MD3161)

Bob:

We have reviewed your 4/20/07 response and determined that we need additional information (see below) to complete our review. Consistent with our review process set forth in NRR Office Instruction LIC-101, Rev. 3, we would like to first discuss this information need with you in a conference call:

(1) The response to Request 2 states that out-of-tolerance is defined as exceeding the band established around a desired value.... However, the licensee has not defined how this band is established. Provide the information about what uncertainties are included in the out-of-tolerance band, basis for their inclusion, and how it is calculated.

(2) The response to Request 2 states that "An as-found condition that exceeds the calibration tolerance......." However, the licensee has not defined how the calibration tolerance is determined. Provide the information about the uncertainties included in the calibration tolerance band, basis for their inclusion, and how it is calculated.

(3) The response to Request 2, on page 3, first full paragraph provides the example of Unit 1 calibration tolerance but did not state that the same value has been used for Unit 2 also and how it was determined. Provide the calibration tolerance band for Unit 2.

(4) The response to Request 2, on page 3, first full paragraph states that the out-of-Tolerance evaluation may include changes to the acceptance criteria, changes to switch design or calibration method (including the setpoint value), or the replacement of poorly performing components, but did not provide any detail on how it is determined and who makes that determination and how soon this evaluation is completed. Provide the missing information.

This e-mail aims solely to prepare you and others for the proposed conference call. It does not formally request for additional information, and does not convey any formal NRC staff position.
