Ginna has passive Gamma monitoring both at the RCA exit (Argos5-Zeus) and plant egress (GEM5). We performed a study documenting sensitivity and acceptability of these devices for passive monitoring and do not require an additional exit WBC. ANI and INPO (05-08) have guidance on demonstrating gamma portal monitors have acceptable sensitivity.

Ginna Nuclear Power Plant 1503 Lake Rd Ontario, NY 14519 From: Sewell, Linda [mailto:[email protected]] Sent: Tuesday, November 24, 2015 1:37 PM To: [email protected] Subject: [EXTERNAL] [powernet] Whole Body Counting Benchmark Hi All, I don't see a recent benchmark on this subject. Does your site perform exit whole body counting? If no, do you have any special documentation for passive monitoring or just take credit for the normal RCA egress process? For Diablo Canyon we currently do perform exit whole body counting. Thanks and Happy Thanksgiving, Linda Linda M.
