Diablo Canyon response below: From: [email protected] [mailto:[email protected]] On Behalf Of LaFrate, Patrick Sent: Saturday, January 05, 2013 6:21 AM To: [email protected] Subject: Powernet: TLD Take Home Policy survey
1. Does your station require individuals to leave their personnel TLDs onsite upon exiting or do individuals take them home? YES 2. What are the principle benefits of the policy you have adopted? Background control, convenience for changeout, temperature variations in local area. We did a study a number of years ago and found 10-30% fade (anneal) when TLDs were left in cars during off hours for a quarter. Temperature loggers showed internal temperatures in some areas to the car well over 100 degrees. 3. Have you changed this policy in the past 10 years and, if so, why? No 4. For multi-site nuclear fleets, is this policy consistent across your fleet or is it site specific due to operating/radiological conditions (i.e. BWR vs PWR; varying site radiation backgrounds due to operating chemistry regimes, etc.). N/A Thanks in advance for any feedback. I appreciate it.
