European pressurized water reactors

A concept of an evolutionary reactor is pursued with the joint French / German European Pressurized Water Reactor , EPR, a 1525 MW(e) plant with evolutionary steam generating system and innovative double-walled containment [20]. A three years basic design phase as a prerequisite for the beginning of the licensing procedure was finished in 1997. The characteristic feature is a core catcher to restrict a possible core melt to the power plant itself. The joint effort by Germany ind France, however, finds in both countries a situation where no further base load is required. The EPR, confirmed as a future standard in France, is projected to substitute decommissioned nuclear plants. 

In February 1995, a contract was signed by German and French utilities and reactor manufacturers including Nuclear Power International, to enter a Basic-Design Phase for the European Pressurized Water Reactor, EPR. An accord was also reached between the French DSIN and the German Federal Ministry BMU on basic safety requirements for future nuclear power stations. 

Innovation options in the nuclear sector include the development of small to medium capacity plants (200-500 megawatts [MW]), evolutionary concepts for the European pressurized water reactor (EPR), Generation IV reactors that reduce waste production, and alternatives to uranium.

At time of writing, Electricite de France (EDF) is about to make a decision to finally commit fuUy to the constraction of a large new twin pressurized water reactor (PWR) at Hinkley Point, Somerset, in the UK. The plant will be two European Pressurized water Reactors (EPRs), designed by Areva and built by EDF. Similar plants are already in construction at Olkiluoto (Finland), Flamanville (Normandy, France), and Taishan (China).

This report examines the severe accident sequences and radionuclide source terms at the Sizewell pressurised water reactor with a prestressed concrete containment, the Konvoi pressurized water reactor with a steel primary containment, the European Pressurised water Reactor (EPR) and a boiling water reactor with a Mark 2 containment. 

This report examines the severe accident sequences and radionuclide source terms at the Sizewell pressurised water reactor with a piestressed concrete containment, the Konvoi pressurized water reactor with a steel primary contaimnent, the European Pressurised water Reactor (EPR) and a boiling water reactor with a Mark 2 containment. The report concludes that the key accident sequences for European plant designs are transient events and small loss-of-coolant accidents, loss of cooling during shutdown, and containment bypass sequences. The most important chemical and transport phenomena are found to be revaporisation of volatile radionuclides from the reactor coolant system, iodine chemistry, and release paths through the plant. Additional research is recommended on release of fission products from the fuel, release of fission products from the reactor coolant system, ehemistry of iodine, and transport of radionuclide through plants.
