Thermal Transient Testing of High-pressure Safety Injection Reactor Pumps

High-pressure safety injection pumps are rigorously tested to ensure they can be relied on to meet their critical safety function.

In a pressurized water reactor (PWR), heat generated by the nuclear reaction is transferred to steam generators by reactor coolant pumps via the primary loop piping.

A failure of the primary loop piping is referred to as a loss-of-coolant accident (LOCA). PWR reactors must be designed to handle any primary loop failure, whether small or large, because the core of the reactor will melt if it is not continuously cooled.

High-pressure safety injection (HPSI) pumps are used to keep the core flooded and cooled in the initial stages of a LOCA. Accordingly, these pumps are a key part of one of the most important safety systems in a PWR power plant.
