Dry cooling capability allows siting in locations without a source of cooling water. If the reactor is to become part of a hydrogen economy , the coolant outlet temperature of 850°C would allow the sulfur iodine cycle to be used which directly converts thermal energy into hydrogen (without electric or other intermediate steps) with an overall ...

In events where the reactor coolant pressure boundary remains intact, the Isolation Condenser System (ICS) is used to remove decay heat from the reactor and transfer it outside containment. The ICS system is a closed loop system that connects the reactor pressure vessel to a heat exchanger located in the upper elevation of the reactor building.
This also increases the capital cost and complexity of a PWR power plant. The high temperature water coolant with boric acid dissolved in it is corrosive to carbon steel (but not stainless steel); this can cause radioactive corrosion products to circulate in the primary coolant loop. This not only limits the lifetime of the reactor, but the ...

The main change, and the most radical among the CANDU generations, is the use of pressurized light water as the coolant. This significantly reduces the cost of implementing the primary cooling loop, which no longer has to be filled with expensive heavy water. The ACR-1000 uses about 1/3rd the heavy water needed in earlier-generation designs.
With winter here, many pawrents are pulling out their pooches' cold weather gear to keep them warm when heading outdoors. Maxine Fluffyroad is an internet famous Corgi, and her dad Bryan recently ...
