It is also known as the light water graphite reactor (LWGR). As with a boiling water reactor (BWR), water boils in the fuel channels (at about 6.9 MPa) and steam is separated above them in a single circuit. It was designed over 1964-66 and is very different from most other power reactors. Its precursors were an experimental 30 MWt (5 MWe) LWGR .

For light-water reactors (LWRs), the containment design has been based on considerations other than severe accidents, including the consideration of the containment during a loss-of-coolant accident. The resulting containment designs for certain pressurized LWRs were then assessed and shown to have adequate resistance to severe accidents.
