North Anna Power Station is reviewing their current practice of evaluating and accepting the identification of peaks in the various MCA's used at the site. This includes whole body counters (WBC) and count room MCAs. We would appreciate information about your standards and bases for accepting or rejecting peaks that have a high relative error noted in the print outs from your software and how you came to and justify that particular standard.
Thanks in advance for responding directly to Rick Adams at [email protected]<mailto:[email protected]>. Upon request, I will make the final results available to anyone that requests and supplies information by November 21, 2013. An example is included below along with space that I'd appreciate you using so I can cut and paste the results. If you do not want your plant named in what I share please say so. Again thanks for your consideration.
