Naureen, North Anna still uses the DMC-2000 GNs for neutron exposure. We have not switched over to the DMC 3000 Neutron Modules. We would be interested in any results you can share with the new DMC-3000 neutron dosimeters.

RSCS does the neutron calibration for us. We used the REM500 to establish a correction factor which RSCS applies after they perform the calibration. We still use our population of DMC2000GNs, also. Even though we make numerious power entries, most neutron exposure is during Dry Cask Storage. It will be later this year before we have any DLR neutron dose to do any comparison.

I am planning to test them in the neutron prone area of the plant. Prior to do that I want to do a quick bench marking on the usage of it. Is there anyone using these DMC 3000 Neutron Modules for the neutron dosimetry? How did you find it compared to using a REM ball based Neutron Meter? Or what do you use in your facility to do the neutron dose measurement? Your input you will be greatly appreciated. Naureen M.
