Introducing the EU-APWR

摘要

Mitsubishi HeavyrnIndustries, Ltd. (MHI) has designed a 1700MWe class advanced pressurised water reactor for Europeanrnutilities. The plant, called EU-APWR, has a basic plant configuration similar to that of conventional PWRs, but various advanced technologies have been adopted to achieve enhanced safety, reliability, and economy.rnEU-APWR is designed as a larger-scale version of the Japanese APWR, aiming at higher electrical outputs to satisfy European utility requirements (see Table 1). The design concept is similar to the US-APWR (see NEI March 2007, p18-20) for which a design control document (DCD) was submitted to the US Nuclear Regulatory Commission on 31 December 2007 and docketed on 29 February 2008.rnThe EU-APWR is a four-loop pressurised water reactor with a power rating of 4451 megawatt thermal (MWt) and a nominal gross electrical output of 1700 megawatt-class electric (MWe). Its core consists of 257 fuel assemblies, with an active fuel length of 14ft. The fuel assemblies are surrounded by a stainless steel radial reflector, designed to improve neutron utilisation, which reduces fuel cycle costs and reactor vessel irradiation. Both the EU-APWR and the Japanese APWR have much larger thermal outputs than the conventional PWRs.
