Flowserve US and CORE Energy’s Collaboration Marks Historic First-Ever Transfer of PCP Technology to India under India-US Civil Nuclear Cooperation
New Delhi, September 2, 2025: In a landmark first for India’s nuclear sector, CORE Energy Systems Ltd. and Flowserve US Corporation have entered a strategic collaboration to locally manufacture Primary Coolant Pumps (PCPs) a milestone that strengthens India’s nuclear PHWR fleet and also advances the U.S.–India 123 Civil Nuclear Agreement. The localisation of this manufacturing work signifies a major advancement in India’s capacity to independently build, operate, and expand its civil nuclear fleet.
This collaboration has been formalized by the Flowserve US and CORE leadership in a signing ceremony in Washington, DCin front of officials from the U.S. Department of Energy and the Indian Embassy, underscoring the strategic importance of U.S.-India civil nuclear cooperation. PCPs are among the most technologically intensive and critical components of a nuclear power plant, enabling a continuous coolant supply to remove heat from the reactor core protecting the reactor and ensuring uninterrupted, safe power generation. Localising the production will build domestic capability, supply-chain resilience, and vendor ecosystems — reinforcing India’s nuclear programme in line with Atmanirbhar Bharat.
The pumps were designed with a strong emphasis on reliability and ease of maintenance. Flowserve US has more than 5,000 pumps and 15,000 valves installed in India. more than 200 nuclear reactors worldwide. The first primary coolant pumps went into service in the 1960s and approximately 245 of them continue in operation today in 57 reactors in 7 countries. Flowserve US is very active in the global nuclear industry, working to enable the rapid deployment of large reactors and small modular reactors, and the life extension, power uprates, and restarts of operating reactors. First-of-Its-Kind Technology Transfer Approved
In a watershed moment for Indo-U.S. strategic collaboration, the U.S. Department of Energy (DOE) has granted Flowserve US specific authorization under 10 CFR Part 810. This authorisation enables Flowserve US’s advanced PCP technology to be transferred to India, reflecting the trust and depth of bilateral nuclear cooperation. Earlier, in November 2024, India’s Department of Atomic Energy (DAE) authorised CORE to collaborate with Flowserve US, with an assurance to the U.S. that the transferred technology will be utilised exclusively for peaceful civil nuclear activities meeting the terms of U.S. Government requirements. It marks the very first U.S. authorisation for an Indian collaboration of this nature and scope, catalysing sovereign local manufacturing of this mission-critical nuclear reactor equipment.
Supporting India’s Nuclear Ambitions and ‘Make in India’ Vision India currently operates 25 nuclear reactors generating 8,880MW, with eight new units (6.6GW) under construction and an ambitious target of 100GW of nuclear capacity by 2047—central to the national vision of Viksit Bharat and Net Zero. The localisation of PCP manufacturing is a decisive step to build a resilient domestic supply chain, unlocking new capacity, supporting private participation, and reinforcing energy self-sufficiency under the “Make in India” and “Atmanirbhar Bharat” initiatives. During the visit of Prime Minister of India to U.S. in February 2025, both the Leaders, Prime Minister Narendra Modi and President Donald J . Trump, announced their commitment to fully realize the U.S.- India 123 Civil Nuclear Agreement by moving forward with plans to work together to build U.S.- designed nuclear reactors in India through large scale localization and possible technology transfer. This collaboration between Flowserve US and CORE is a direct step toward realising that vision.
Statements from Leadership
“As a global leader in flow control technology and solutions for the nuclear power industry, Flowserve US is excited to receive official approval from the U.S. Department of Energy to manufacture safety-critical pumps for India’s reactors at our Coimbatore, India facility,” said Ihab Botros, Vice President and General Manager for Engineered Pumps, Flowserve US. This achievement, made possible through our collaboration with CORE, marks a significant step forward in India’s nuclear growth and the global clean energy transition. With more than 5,000 pumps operating in 200+ reactors worldwide, Flowserve US brings proven global expertise to support India’s growing nuclear ambitions, and we see India as an important part of the industry’s future.”
“For over two decades, CORE has driven India’s strategic engineering journey,” added Nagesh Basarkar, Chairman & Managing Director, CORE Energy Systems Ltd. “This collaboration to indigenously manufacture PCPs not only delivers world-class technology to our nuclear sector but also strengthens national supply-chain resilience. It marks a pivotal milestone in India’s march toward energy independence and a decisive step towards accomplishing the Prime Minister’s vision of Atmanirbhar Bharat.”
Supporting India’s Nuclear Roadmap India currently operates 25 nuclear reactors generating 8,880 MW, with eight new units (6.6 GW) under construction and a target of 100 GW of nuclear capacity by 2047. The localisation of PCP manufacturing marks a decisive step towards building a resilient domestic supply chain for nuclear-grade components supporting private participation and aligning with the national vision of Viksit Bharat and Net Zero.
Alongside, training and upskilling initiatives will foster a new generation of Indian nuclear technologists and suppliers, ensuring India’s civil nuclear programme is equipped to sustain its unprecedented expansion for decades to come.”
