Robinson uses same practice for characterizing filters. From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Tuesday, May 31, 2011 7:51 AM To: [email protected] Subject: Re: Powernet: Characterization of cartridge filters
Cook Plant does a smear on the filter or filter housing or both. Then dose to curie calculations are done to determine amount. The practice has not been questioned by the regulator here.

At Ginna, our practice is to take a core-bore type sample of each filter. The nuclide information obtained is then used to perform dose-to-curie evaluations. We have been challenged as to whether this practice is efficient and ALARA. What is everybody else doing? - "Core-bore" sample of each filter? - "Core-bore" sample of a representative selection of filters? o How do you ensure your selection is representative? - Smears? o Where/how many? - Something else? Have your chosen techniques been questioned/challenged by the regulators?
