In a reactor core isolation cooling system ("RCIC"), an isolation condenser (IC or iso. condenser; also isolation condenser system) is one of the emergency reactor safety systems in some nuclear plants (boiling water reactor safety systems).
Unit 1 was a 460 MW boiling water reactor from the BWR-3 design iteration introduced in 1965 and constructed in July 1967. ... It also had an isolation condenser, and ...
Some reactors, including some BWR/2 and BWR/3 plants, and the (E)SBWR series of reactors, have a passive system called the Isolation Condenser. This is a heat exchanger located above containment in a pool of water open to atmosphere.
A boiling water reactor (BWR) is a type of nuclear reactor used for the generation of electrical power. ... Another example was the Isolation Condenser system, which ...
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.
The Isolation cooling system is a defensive system against a condition known as station blackout. This system is not part of the ECCS and does not have a low coolant accident function. For pressurized water reactors, this system acts in the secondary cooling circuit and is called Turbine driven auxiliary feedwater system .
A BWR's containment consists of a drywell, where the reactor and associated cooling equipment is located, and a wetwell. The drywell is much smaller than a PWR containment and plays a larger role. During the theoretical leakage design basis accident, the reactor coolant flashes to steam in the drywell, pressurizing it rapidly.
The BWRX-300 is a smaller evolution of an earlier GE Hitachi reactor design, note the Economic Simplified Boiling Water Reactor (ESBWR) design and utilizing components of the operational Advanced boiling water reactor (ABWR) reactor. [1] Boiling water reactors are nuclear technology that use ordinary light water as a nuclear reactor coolant ...
