CORE Energy Systems

CORE Energy Systems is a nuclear-qualified engineering and EPC company headquartered in Navi Mumbai, India – the first Indian company authorised under U.S. DOE 10 CFR Part 810 and the team behind Asia's first primary recirculation piping replacement at Tarapur Atomic Power Station Units 1 & 2, the world's oldest operating commercial BWRs. That life-extension project won the World Nuclear Exhibition Innovation Award 2025 in Paris.

We deliver end-to-end nuclear capability: design and engineering, nuclear-grade manufacturing, turnkey EPC, and lifetime operations and refurbishment support. CORE operates three nuclear-grade manufacturing facilities and is certified to ISO 19443 – the international standard for nuclear supply chain quality – as well as to ISO 9001, 14001, and 45001. Our 500+ strong engineering team has delivered over 18 million EPC man-hours across mission-critical projects in nuclear, defence, oil & gas, aerospace, and clean energy.

CORE holds a licensing agreement with Flowserve Corporation (USA) to manufacture critical nuclear flow-control equipment in India – a partnership that underscores our role as a qualified manufacturing base for global OEMs entering or expanding in the Indian nuclear market.

With a growing international footprint spanning the United Kingdom, Russia, Kenya, and Zambia, CORE is a proven partner for global nuclear OEMs, utilities, and technology developers seeking certified manufacturing, life-extension expertise, and EPC delivery capability in one of the world's fastest-growing nuclear markets.
