US-based Flowserve and India’s Core Energy Systems Ltd have formed a collaboration to locally manufacture primary coolant pumps for India’s pressurised heavy water reactor (PHWR) nuclear plants in a “landmark” move that accelerates the realisation of the US-India 123 Agreement.

Flowserve said the localisation of this manufacturing work signifies a major advancement in India’s capacity to independently build, operate and expand its civil nuclear fleet.

Primary coolant pumps are the technologically most intensive and critical equipment for any nuclear power plant. They provide a steady coolant supply to remove heat from the reactor core, protecting the reactor and enabling continuous, safe power generation.
