Principal available reactor designs Seven of the designs EPR, VVER-1200, APR-1400, AP-1000, APWR, Atmea and CPR- 1000 are variants of Pressurised Water Reactors (PWRs). VVER is the Russian acronym for PWR. The VVER design is similar to PWRs but employs horizontal steam generators. SNC Lavalin s(formerly AECL) CANDU is a heavy-water moderated, pressure tube design, with separate horizontal pressure tubes for each fuel channel, in a primary circuit with steam generators, a pressuriser, and primary pumps. GE-Hitachi s ESBWR is the latest version of their Boiling Water Reactor (BWR). This design differs from all the others in that the steam generated in the RPV passes straight to the turbine, so the turbine operates using mildly radioactive steam. PWRs, CANDUs and BWRs are all fundamentally proven designs in widespread use around the world. The versions listed here are the most modern variants which are currently offered by the designers. Current status of the ArevaKerenaBWR is unclear (following Siemens withdrawal from nuclear construction projects after Fukushima). Modern nuclear power plants are all designed for a nominal 50 to 60 year life. Site construction time for all designs is usually stated to be in the range 42 to 60 months. All designs except CPR-1000 are Generation III+ designs which are said to offer significant improvements in safety and economics over the Generation III advanced reactor designs certified by the US NRC in the 1990s.

ArevaEuropean Pressurised Water Reactor (EPR) Based on French N-4 and German Konvoi 1600 MWe Advanced safety systems First EPR is close to completion in Finland Construction in progress in France and China More are planned in France and the UK Currently being evaluated in UK Generic Design Assessment This design is the front-runner for UK new reactors Design of Control and Instrumentation systems has been changed due to UK and Finnish concerns Electricitede France (EdF) and Arevaplan to build four units in the UK Horizon Power (joint venture between Germany s E.On and RWE) is also considering this design January 2012 4
ArevaKerenaBWR 1250MWe Boiling Water Reactor Used Gundremmingen BWR plant in Germany as basis Advanced safety features Load-following design The current status of this design is unclear following Siemens withdrawal from new nuclear projects January 2012 5
Areva-Mitsubishi Atmea 1100MWe plant, 3-loop Based on 900MWe Framatome-EdF unit design Claimed Generation III+ safety features Load-following design Smaller size (than EPR) intended for countries with smaller grids No orders yet (Jan 2012) January 2012 6
AtomstroyexportVVER-1200 1200 MWe Includes some passive safety features Planned construction in Russia, China, Vietnam and Turkey Tianwan twin VVER plant, China Developed from earlier VVER-1000 designs There are currently at least twelve units under construction in Russia 4-loop design, horizontal steam generators Advanced safety features including 72 hour site blackout capability January 2012 7
CNGPC CPR-1000 Chinese development of French 3-loop 900MWe design (Gravelines is the reference plant) At least 20 are currently in advanced planning or under construction. Chinese plan to have 100 units operational by 2030, most of which will be CPR-1000 units. This is a Generation II design the Chinese authorities have said they are reviewing for extreme external events and site black-out, post-fukushima. January 2012 8
GE-Hitachi ESBWR Economic Simplified Boiling Water Reactor 1600 MWe Passive safety features Modular construction The design was initially submitted to UK Generic Design Assessment but GE withdrew because some aspects of the design were not sufficiently mature An earlier version, the ABWR (Advanced BWR), is in operation in Japan and Taiwan First ABWR began commercial operation at Kashiwazaki-Kariwa in Japan, in 1996 January 2012 9
KEPCO APR-1400 1400MWe PWR Based on the Westinghouse/CE System 80+ at Palo Verde USA Four APR1400 are under construction in South Korea, first due to go to power in 2013 KEPCO has won a tender to supply four APR1400 units to the United Arab Emirates First UAE nuclear power plant will be the fifth unit of the APR1400 plants in the world South Korean Shin-Kori plant will serve as the "reference plant" for the UAE program KEPCO design was not submitted for the UK Generic Design Assessment January 2012 10
Mitsubishi APWR 1700MWe, 4-loop design Generation III design 2 units were planned for construction at Tsuruga, Japan, but this has been cancelled post-fukushima. The design is undergoing certification by US authorities for possible construction at Comanche Peak, Texas and North Anna, Virginia Mitsubishi has partnered with Iberdrolafor possible APWR construction In Europe January 2012 11
SNC LavalinAdvanced CANDU Reactor 1200 MWe horizontal fuel channel core heavy-water moderator on-power fuelling (ACR-1000) Was in UK s Generic Design Assessment AECL withdrew from assessment ACR development has been put on hold because there s no market demand (Toronto Star 27th Oct 2011). The older CANDU 6 design is still being offered, however. Not built anywhere yet but CANDU 6 (the preceding design) has been built in South Korea and China. Differences from earlier CANDU designs: compact core design enriched fuel improved stability higher output light water coolant less heavy water than earlier CANDUs SNC Lavalinbought AECL in 2011.

Toshiba-Westinghouse AP1000 1100MWe PWR Passive safety systems Modular construction At least four units under construction in China Currently being evaluated in UK Generic Design Assessment Horizon Power (RWE/E.On) are considering AP1000 as an option to Areva EPR. One novel aspect is the use of explosive squib valves These deliberately breach primary coolant circuit in accidents to enable passive cooling Design operation and maintenance of squib valves will be key aspects of safety approval January 2012 13
