RAI 15.5-1 Response needed to complete draft SE

Dan, The original RAI and the response from the 30AUG2010 letter is shown below. The answer did not provide the requested information. The response did not identify all the changes made from the CLB of Unit 1 to license Unit 2. A phone call was made on 20SEP2010 to clarify exactly what information is needed. The question was restated to clarify that any changes to the CLB for Unit 1, which is being used as the base line for the licensing of Unit 2, would only apply to Unit 2. The restated RAI is as follows:

Please provide additional information describing, for each design basis accident described in FSAR Section 15.5, all the basic parameters used in the dose consequence analyses. For each parameter, please indicate the Unit 1 CLB value, the revised value where applicable as will be applied to Unit 2, and the basis for any changes made to the Unit 1 CLB values. The NRC staff requests that this information be presented in separate tables for each accident evaluated.

Original RAI and response:
