Three Mile Island on the Susquehanna River is located about 16 km SE of Harrisburg Pa, USA. It is a flat island with a surface of several square kilometres. Some years ago it was chosen as the site for a nuclear power station with two units named TMI-1 and TMI-2. Each unit has its own reactor and turbine-generator group for the conversion of steam into electric energy. The two units could supply 1700 MW to the grid, sufficient for the needs of 300 000 families (based on the average consumption of a US family). 

CDFR is a pool-type SFR with a preliminary designed thermal power of 2100 MW and an electrical power of 870 MW. Mixed oxide (MOX) is used as the fuel, and sodium is the main coolant. The reactor is a three-loop, three-circuit design, and there is only one set of steam turbine generators. Fig. 14.5 shows the preliminary core layout of the CDFR (Yang et al., 2007). It was planned to be constructed in Xiapu, Fujian province, under the cooperation of the China National Nuclear Corporation (CNNC), the Fujian Investment and Development Group, and the Xiapu state-owned assets investment management company with the investigation ratio of 51 40 9.
