RE: Question arising from the Duke Meeting yesterday on Major Project Plans
- Melanie, I believe they must be referring to ANSI/ANS-58.21-2007 "External-Events PRA Methodology". Under High Level Requirement A: Flood Hazard Analysis (page 84), the following statement is made:

There is also an older ANSI/ANS standard that may have language similar to the above. I will look into it and I will let you know shortly.

Question arising from the Duke Meeting yesterday on Major Project Plans
- Fernando, Mark mentioned that in the Duke meeting yesterday that Duke noted that there was a standard (ASME or ANS or ANS/ASME) that noted an external hazards initiating event frequency for dam failure and seemed to further indicate that it was in line with our estimate of 1 OE-4.
With your previous exercise in researching and summarizing relevant info from the regs, SRP, RGs and standards, can you track this reference down and provide us with the exact quote?
Thanks.
