Benchmarking question:
At VC Summer we have detailed procedure guidance for the
operators on how to withdraw control rods during the approach to criticality. However,
we do not have any procedure guidance on how to withdraw shutdown bank control
rods. Some of our operators withdraw the shutdown banks continuously
while watching other indications. Some of them stop every 25 steps to
look at other indications, and then continue on. Others stop every 25
steps and ask for supervisor concurrence before continuing.
What kind of guidance do your plants have
on withdrawing shutdown banks? You can email me at the
address below, and I will compile all the responses and share them with the
entire group. Thanks in advance for your help.
