Fwd: RE: CR Fire CDF Value Clarification Chris - In addition to confirming that the IPEEE control room fire CDF reported in the ER was incorrect (should have been 1.43E-6 rather than 6.31 E-5), it would be a good idea to have WCNOC also confirm that the value of 2.22E-6 reported in the ER for the fire re-analysis is correct, and that the CR fire frequency actually increased in the fire re-analysis (the ER states that it decreased, but that statement appears incorrect given the correction to the IPEEE value).

- Bob, See attached email from Charlie (Wolf Creek). He confirmed that they used the incorrect number, and that you and Bruce are correct in using the IPEEE number. I'm thinking I can just add the email to ADAMS and this will resolve the issue. I don't think I need to ask them to send this info under oath and affirmation since the 1.43 number is something that we can can reference from IPEEE. Do you agree?
