At St. Lucie, we also use the temporary reactor head (TRH), and it is placed in
the reactor cavity (and removed) with the cavity filled to refueling level
(i.e., we don't drain the reactor cavity, just below the TRH).
So, there are no dose issues, just contamination control issues.

Subject: [powernet] Dose Control on refuel floor for drain down to Mid-Loop at
PWRs
CAUTION - EXTERNAL EMAIL
At Palo Verde, a Temporary Reactor Head is used when draining down to Mid-Loop.
This allows us to refill the refuel cavity with water to reduce dose.
Does your site use a Temporary Reactor Head? If not, what methods are used to
control dose or reduce dose rates on refuel floor.
Thank you,
