You would never operate with all control rods fully withdrawn. That would mean that you are outside the control limits for the plant, and there is the potential for going prompt, or superprompt, critical, which is not a good state to be in.

When control rods are withdrawn in Pressureize water reactor in what pattern should the sets be in?
they are usually removed one after the other to maintain stability
What is the purpose of the control rod?
The control rods in a nuclear reactor are simply neutron absorbers which can be raised or lowered, this enables the reactor to be maintained at criticality with the chain reaction proceeding at a steady rate. The reactor loses reactivity between refuellings which are probably every two years, so the control rods have to be slowly withdrawn to compensate. They are also fully inserted very quickly should the safety instruments require it, and the reactor then stays shutdown. (Reactor scram or trip)
Control rods are used in a reactor core to?
Reactor control rods are made of a substance that absorbs neutrons.
What is the role of control rods in a fission?
what is the role of control rods in a fission reaction
What is the function of a control rods reactor?
Control rods are used in a reactor to control the rate at which fission happens.
Can plutonium be used as control rods?
Plutonium is used for nuclear fuels not for control rods.
What is the role of control rods in a fission reaction?

What rods housed within a nuclear reactor?
fuel rods and control rods
What are control rods during a nuclear reactor?
The control rods are neutron absorbers that can be moved up and down to vary the amount of absorption and so keep the reactor at a steady power or raise/lower power. They also shut the reactor down and hold it down when fully inserted.
The chain reaction in a nuclear reactor is controlled by inserting what?
control rods.
Which safety feature works to slow down nuclear fission chain reactions?
control rods APEX USERS
What does lower control rods result in?
We lower control rods to cool or shut down a nuclear reactor. Lowering control rods allows those rods to absorb more neutrons, and this limits or shuts the fission chain down.
