ABSTRACT:
An improved pressurized fluid reactor system having a fluid cooled reactor core in which the coolant pump for delivering fluid to the reactor core is driven by a pump motor through a unidirectional drive means which enables the pump to operate at a greater speed than the pump motor in the pumping direction only. A preferred unidirectional drive means in the form of a ratchet means is disclosed.
