Czechoslovakian company SKODA JS said this week that it had finalized negotiations with French company Framatome with a contract to supply two sets of EPR 1600 reactor pressure vessels internals that are slated for the Hinkley Point C nuclear plant in Somerset, Great Britain.
The specific components in the contract include core barrel, heavy reflector and “Upper Internals,” which Skoda said was the equivalent to the upper block of a VVER 1000 reactor.
The Core Basket weighs approximately 80 tons. It is a welded and machine structure made of stainless steel designed for placing the reactor core and for directing and smoothing the distribution of coolant to the reactor core.
Heavy Reflectors, which consists of stainless steel in machined slabs with cooling orifices, weighs about 100 tons. This acts as a neutron reflector, Skoda said.
The Upper Internals, weighing about 80 tons, are welded structures with tubes that guide the intermediate drive rods controlling the reactor output.
Skoda noted that the contract “concurs similar supplies of company Skoda for its French partners for nuclear power plant projects in Finland and China. In 2010, the company supplied similar products for the Olkiluoto 3 construction project. In 2012, a contract similar in scope supplied parts for Taishan 1 in China.
