SCWR for Future Large-Scale Nuclear Power Generation

The ambitious nuclear power program motivates the Chinese nuclear community to develop advanced reactor concepts of generation IV,in order to ensure the long-term,stable and sustainable development of nuclear power.The supercritical water-cooled reactor(SCWR)has favorable features in economics,sustainability and technology availability.It is the logical extension of the existing PWR technology and has very promising perspectives in large-scale power generation in China.This paper describes the main features of SCWR.New designs of SCWR core structure and fuel assemblies are proposed.Preliminary analysis using a coupled neutron-physics/thermal-hydraulics method is carried out and shows a good feasibility of the new design proposal.
