From: Lee, Sun G. [mailto:[email protected]] Sent: Tuesday, April 12, 2016 6:39 AM To: '[email protected]' Cc: Lee, Sun G. Subject: [powernet] Dry Cask Storage - neutron energy evaluation and n-ED TVA External Message. Please use caution when opening. Perry Nuclear Power Plant would like to know: 1 – During your initial dry cask storage campaign, did you characterize the neutron energy field? Not that I can find, so I believe the answer is no. 2 – After the initial dry cask campaign, have you re-evaluated the neutron energy for subsequent campaigns for establishing correction factor for TLDs? We are current performing this evaluation. We are on the last MPC and will be analyzing the data collected and writing a report soon. 3 – What was the basis for the decision on question 2? ANI Bulletin 11-02 4 – Have you implemented neutron electronic dosimeters for dry cask storage? Yes, we have use them this campaign. The electronic dosimeter neutron response has an negative bias of approximately 5 to 10% based on comparisons to a REM-500 and CR-39 response. The REM-500 and CR-39 response has typically been within 2-3%. Thank you. Sun G. Lee, CHP Technical Support Perry Nuclear Power Plant 440-465-8030 Cell 440-280-5039 Work Sun G.
