I have an action to change our FSAR for stored radioactivity in our CST and 
RWST tanks outside of the RCA. We currently have 0.5 and 10 mR/hr contact dose 
rate limits on these tanks. I would like to know the following;



a)       What are your FSAR limits (dose rates or concentration levels), and 
how did you come up with these numbers?


b)       What is your process to monitor these tanks to make sure you comply 
with your FSAR requirements?



 Thanks for your help,
