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?
