Re: [Powernet] HPPOS-189 Transfer of Exempt Quantities of Byproduct Material

We do not do this at Ginna. Oil samples from the RCA are sent to a licensed facility unless they meet the criteria for unrestricted release. Seems like there could be a challenge to validate no "no special nuclear material or byproduct material other than that included in 10CFR71 Schedule B"

[Powernet] Benchmark - WBC Check Source

This benchmark is primarily for those of you using a Germanium based whole body counter...I welcome feedback from everyone, however Questions (with Ginna info) 1. What WBC system are you using? Mirion/Canberra Accuscan-II with dual HPGe detectors 1. What nuclides/peaks are you using to

Re: [Powernet] Alpha Determination

We would use an alpha frisker if greater than 100k dpm beta. However, our "high contamination" is about 20 mrad/hr rather than 15 R/hr. Although EPRI would specify alpha counts in this situation, I think you've identified what your real radiological risk would be for this work. Hopefully, you

Re: [Powernet] Portable Radiation Instrument Performance Checks

1. Do you require a daily or prior to use source response check for instruments? Yes, qualitative response to a known radiation source on a single scale 1. If you require a daily source response check, is this documented or part of the user’s instrument checks? Yes, documented on source

Re: [Powernet] Neutron dose tracking

1. Primarily neutron SRDs 2. If area hasn't been characterized for neutron SRD energy response, preferred technique is timekeeping with REM500 3. No 4. Yes. We have one neutron source and we require neutron dosimetry and neutron surveys when working with this source 5. Only
