Beaver Valley response:
We use spreadsheets to perform some reactor engineering surveillance calculations. The reviewer independently verifies the calculations either by hand, or an independent spreadsheet.

Please respond to PWR Reactivity Management <pwrrm@retaqs.com >
We at STP use spreadsheets to perform surveillance calculations. The results are then independently verified by a second engineer using an independently generated spreadsheet. Neither spreadsheet has been formally verified per our station Software Quality Assurance procedure. In cases where the results are used without further verification, we do properly QA the spreadsheets (usually in the cases where other groups use the spreadsheets).
Our QA department is of the opinion that at least one of these spreadsheets used for surveillances must by fully verified and documented per our station Software Quality Assurance procedure.
It would help my case if I could cite other Rae’s practices with regards to the use of spreadsheets. What is the practice at your plant?
Thank you,
Duane Gore Supervisor, Reactor Engineering STPNOC
