FTL010H-A10 Fuji Module

Product Description:

The nuclear steam supply system (NSSS) consists of a reactor core, pipes, pumps, a heat exchanger (HX), and a steam generator (SG), which supplies steam to a turbine/generator (T/G), as is shown in Figure 1. This figure shows only one loop, but a loop can be redundant depending on a plant size or a need for flexibility.
MSR-FUJI is designed to produce an exit temperature of 704??C in molten fuel salt, and its heat is transferred to the secondary salt through an HX. Then, its heat produces 538??C supercritical steam at an SG and generates electricity by a supercritical T/G. Owing to its high temperature, MSR-FUJI can achieve 44% thermal efficiency.
Since molten salt is used as fuel and coolant, loss of coolant accident (LOCA) may need a new definition for MSR. In case of a pipe break, leaked molten salt is drained to an emergency drain tank without passing through a freeze valve. Even in this case, a molten salt loop returns to atmospheric pressure when a pump stops, and a pressurization accident is incredible, owing to its low vapor pressure. Therefore, an emergency core cooling system (ECCS), containment cooling system (CCS), makeup water pools, and automatic
depressurization system (ADS) are not required.
The primary loop (molten fuel salt loop) is operated with forced circulation by a centrifugal pump during normal operation. The system also has a natural circulation capability in emergency conditions.
