Comanche Peak is exactly the same as Palo Verde, including the transition when 
security allowed the security badges to go home... the TLDs remain in storage 
racks outside the RCA.

Subject: Powernet: RE: TLD Take Home Policy survey

Palo Verde requires individuals to leave their TLDs onsite as they exit the 
Protected Area (Radiological Restricted Area).  This allows for better 
background control, physical control, and reduces number of TLDs sent thru the 
x-ray machine when the worker returns to site.  We have had this policy in 
place since day 1.  When Security policies regarding site access badges changed 
(allowed to take home ACAD badge) we devised a drop off and badge storage 
system.

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?



2. What are the principle benefits of the policy you have adopted?



3. Have you changed this policy in the past 10 years and, if so, why?



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.).



Thanks in advance for any feedback. I appreciate it.
