See the St. Lucie response below ... 1. A flow chart is used to drive the method to perform neutron monitoring of personnel. The process evaluates whether the work involves containment entry, ISFSI, a neutron source, or in areas outside the containment (such as by the escape hatch), et

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 accessi
