I noticed that you have not gotten any responses to this question. My
answers are given below. They apply to the now decommissioned Trojan
reactor located in Oregon.

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?
The FSAR limits were concentration of radioactive material based on the
dose to a member of the public from drinking water downstream from the
plant from the total release of the tank contents due to
a rupture. The dose limit to the public was used to back calculate the
maximum concentration based on minimal dilution.
b)What is your process to monitor these tanks to make sure you comply
with your FSAR requirements?
There were no process monitors. A sample was collected for analysis by
chemistry.
Thanks for your help,
