French state-run power utility EDF and American conglomerate General Electric (GE) have signed strategic cooperation agreement with State-run Nuclear Power Corporation of India (NPCIL) to build for construction of 6 EPR (European Pressurized Reactors) type nuclear reactors of capacity 1,650 megawatt (MW) each at Jaitapur nuclear plant in Ratnagiri district, Maharashtra.
This strategic cooperation agreement is for long term partnership for construction of conventional island on each of 6 reactor units of Jaitapur nuclear plant. GE Power will design conventional island for the plant and supply its main components. EDF will supply EPR technology and will be responsible for building and coordinating industrial partners for this project. It will be responsible for engineering integration covering entire project (nuclear island, conventional island and auxiliary systems) and will provide all the requisite input data.
Jaitapur Nuclear Power Plant
It is proposed 9900 MW nuclear power project to come at Madban village of Ratnagiri district in Maharashtra (west coast of India). State-run Nuclear Power Corporation of India (NPCIL) is builder and operator of this plant. It will be built under Indo-France Civil Nuclear Deal signed in December 2010.
It will have 6 EPR designed and developed by Areva of France, each of 1650 MW, thus totalling 9900 MW. EPR is third generation pressurised water reactors (PWR). The estimated cost of this project was around US $15 billion (Rs. 1,000 billion). Consortium of French financial institutions will finance this project as a loan.
The layout of nuclear power plant comprises two major parts — nuclear island and conventional (turbine) island. The nuclear island is heart of nuclear power plant, while conventional (turbine) island houses key component which extracts thermal energy from pressurized steam and converts it into electrical energy.
On completion, Jaitapur power plant would be world’s largest nuclear power generating station by net electrical power rating. It will also play pivotal role in achieving Union Government’s ambitious target of 22,480 mw nuclear power generation capacity by 2031.
The Union Cabinet has cleared a proposal allowing for the construction of 10 indigenous Pressurised Heavy Water Reactors (PHWR). The reactors will have a capacity of 700 MW. These reactors will add 7000 MW capacity and will ramp up nuclear power generation in the country.
Pressurised Heavy Water Reactors
Pressurised Heavy Water Reactors use natural uranium as fuel and heavy water as both moderator and coolant. India’s first PHWR was constructed at Rawatbhata in Rajasthan in technical cooperation with the Atomic Energy Canada Ltd (AECL). However, the Canada’s support was immediately withdrawn after India’s first nuclear experiment at Pokhran in 1974. India’s first nuclear power plant with a different design was built at Tarapur in Maharashtra. PHWR units are in operation in Rawatbhata, Kaiga, Kakrapar, Kalpakkam and Narora. Recently, it was announced that the Nuclear Power Corporation of India Limited (NPCIL) is ready to sell Pressurised Heavy Water Reactors of 220 MWe or 540 MWe capacity to other countries.
