Design
edit
The CAP-1400 is a Pressurized water reactor,in which the primary coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the fission of atoms. CAP1400 has two primary coolant loops that transfer the heat generated by the fission reaction of 235U in the reactor core to the steam generator,each loop consists of a hot leg, two cold legs, one steam generator, and two canned pumps. CAP1400 has one pressurizer (PRZ) connected to one of the hot legs by a surge line.The fuel core of the reactor has 193 fuel assemblies.
CAP-1400 has a design life of 60 years,and has refueling interval of 18 months, and Averaged discharge fuel burnup of ≥50 000MWd·(tU)−1.The system operated pressure is 15.5Mpa,and Coolant average temperature is 304°C, while steam pressure at steam generator is 6.01Mpa,The steam flow at steam generator is around 1123.4kg·s−1.
CAP1400 has a compact and general layout. It covers area of only 0.164 m2·kW−1,which is less than AP1000. Estimated cost of the CAP-1400 is around 16 000 CNY·kW−1($2443 USD·kW−1)
