Cabinet gives nod for 10 indigenous nuclear reactors

What is in news? Image result for nuclear reactors

The Union Cabinet cleared the proposal to construct 10 indigenous pressurised heavy water nuclear reactors with a total capacity of 7,000 MWe

Each of the reactors would have a capacity of 700 MWe

Background:

>The decision comes against the backdrop of recent troubles for India’s international collaborations in nuclear projects

>While the U.S. deal, involving Toshiba Westinghouse for six reactors in Andhra Pradesh, is floundering after Westinghouse filed for Chapter 11 bankruptcy, the deal with French company Areva for reactors in Jaitapur remain mired in negotiations over costing

Benefit:

These 10 plants would create Rs. 70,000 crore worth of business for domestic manufacturers and generate about 33,400 jobs

The approval shows government’s strong belief in the capability of India’s scientific community to build our technological capacities

Rapid advances by India

The design and development of this project is a testament to the rapid advances achieved by India’s nuclear scientific community and industry

It underscores the mastery our nuclear scientists have attained over all aspects of indigenous PHWR technology

The 10 reactors will be part of India’s latest design of 700 MWe PHWR fleet with state-of-the-art technology meeting the highest standards of safety

A Pressurized Heavy Water Reactor (PHWR) is a nuclear power reactor, commonly using unenriched natural uranium as its fuel, that uses heavy water (deuterium oxide D2O) as its coolant and moderator

The heavy water coolant is kept under pressure, allowing it to be heated to higher temperatures without boiling, much as in a typical pressurized water reactor

While heavy water is significantly more expensive than ordinary light water, it yields greatly enhanced neutron economy, allowing the reactor to operate without fuel enrichment facilities (mitigating the additional capital cost of the heavy water) and generally enhancing the ability of the reactor to efficiently make use of alternate fuel cycles

India has this facility in – Tarapur , Rajasthan , Madras, Narora, Kakrapar, Kaiga nuclear power plants
