It does not require an outside power source. Steam generated by the heat of a cooling down reactor has enough force to run a turbine, which then runs a pump that provides coolant to the core.

The sudden shutdown of a pump at PSEG Nuclear's Hope Creek reactor has caused operators to cut power output at the plant in Lower Alloways Creek Township.

Framatome recently completed the refurbishment of 31 reactor coolant pump motors for three southeastern nuclear energy facilities.

A nuclear reactor core is one of the most extreme human-made environments on the planet. These scientists just figured out how to print one.

The Salem 2 nuclear reactor, seen at right, remains shut down after broken bolts were discovered in all four of the reactor coolant pumps at the plant in Lower Alloways Creek Township.

Controlling the power output of a boiling water reactor (BWR)—such as Exelon Nuclear’s Quad Cities Unit 1 or 2 (Figure 1)—requires changing the reactivity of the core by repositioning the ...

One of two reactors has been shut down at a nuclear power plant in western Pennsylvania after a pump that supplies nonradioactive water to steam generators shut down.

The RCPs are part of the reactor coolant system that maintains reactor core cooling and are components of the AP1000’s passive safety system design. Subscribe to Nuclear Power International magazine ...

The reactor vessel assembly consists of the reactor vessel and its internal components, including the core support structures, core shroud, moisture removal equipment, and jet pump assemblies.

The pumps force water back into the reactor core after it circulates through systems that make non-radioactive, pressurized steam used to turn generators.

A nuclear reactor in New York City's suburbs has been shut down to repair a pump that was leaking slightly radioactive water.

Water pump repairs are complete on a Diablo Canyon nuclear power reactor that was shut down for a week after sensors detected a problem at the California coastal plant.
