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 accessible permanently posted neutron area is outside our containment personnel hatch. We survey quarterly

Ginna Nuclear Power Plant 1503 Lake Rd Ontario, NY 14519 From: Powernet [mailto:powernet-boun...@hpspowernet.org] On Behalf Of Beth Heyeck via Powernet Sent: Monday, April 16, 2018 3:33 PM To: powernet@HPSpowernet.org Cc: Beth Heyeck <eahey...@aep.com> Subject: [EXTERNAL] [Powernet] Neutron dose tracking 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: * Stay time tracking * Gamma to neutron ratios * Neutron sensitive SRDs * Other 2. Do you have specific criteria for using any of the above? 3. Are there any exemptions to tracking neutron doses in Neutron Exposure Areas, and how are those documented? 4. Do you track neutron dose outside of Neutron Exposure Areas/when handling neutron sources? 5. How often do you perform neutron surveys of Neutron Exposure Areas?
