North Anna-
1.)Primarily SRD's however we will back that up with stay times and a REM
ball in case we get an anomaly with the SRD which has happened.
2.)No specific criteria other than what's stated above.
3.)No
4.)Yes we have an AmBe source and we track exposure when using
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
We are looking at streamlining our neutron dose tracking and are wondering how
other plants are performing it.
1. Which do you use for determining neutron dose for workers in Neutron
Exposure Areas:
a. Stay time tracking
b. Gamma to neutron ratios
c. Neutron sensitive
CPNPP doesn’t use the 9DP.
We use the Ludlum R9-7
