Abstract
A reactor control system for a nuclear reactor, the reactor control system comprising: one or more hollow tubes comprising neutron absorbing material, each having a first end and a second end; a pump connected to the first end of each hollow tube and operable to control the amount of a first fluid within the hollow tube, the first fluid comprising a neutron moderator, wherein: the pump is controlled based on a level of reactivity in the nuclear reactor, and the second end of the hollow tubes is in fluid communication with a second fluid, the second fluid having a neutron moderating capacity lower than 10% of that of the first fluid.

A reactor control system for a nuclear reactor, the reactor control system comprising:
- one or more hollow tubes comprising a neutron absorbing material, each of the one or more hollow tubes having a first end and a second end;
- a pump connected to the first end of each of the one or more hollow tubes and operable to control an amount of a first fluid within that hollow tube, the first fluid comprising a neutron moderator,
- wherein:
- the reactor control system is configured to control the pump based on a level of reactivity in the nuclear reactor, and
- the second end of each of the one or more hollow tubes is in fluid communication with a second fluid, the second fluid having a neutron moderating capacity lower than 10% of that of the first fluid.
