Correct option is D

The correct answer is (d) Canada

Pressurised Heavy Water Reactor (PHWR) in India
The first Pressurised Heavy Water Reactor (PHWR) in India was set up at Tarapur in 1964. This reactor was a result of collaboration between Atomic Energy of Canada Ltd (AECL) and Nuclear Power Corporation of India Limited (NPCIL).
It marked a significant step in India's nuclear energy programme, enabling India to harness nuclear power for its growing energy needs.

Information Booster
PHWR Technology

• The PHWR is a type of nuclear reactor that uses heavy water (deuterium oxide, D₂O) as both a moderator and coolant.
• The collaboration led to the successful operation of the Tarapur Nuclear Power Station, which initially had two reactors.

Canada's Contribution

• The reactor technology was transferred by Canada, and this collaboration paved the way for future advancements in India's nuclear energy capabilities.
• The expertise gained through the PHWR project greatly contributed to India's indigenous nuclear programme.

Current Scenario

• As of 2025, India has expanded its nuclear power capabilities, with the addition of several PHWR-based plants, notably at sites like Kakrapar, Rawatbhata, and Narora.
