A STUDY OF HEAVY WATER CENTRAL STATION BOILING REACTORS (CSBR)

Reactors designed for economic operation in stationary central power plants were studied. Certain objectives presented themselves as being of particular importance if an attractive economy were to be obtained. These objectives arei use of ceramiic (UO/sub 2/) rather than inetallic fueI; use of natural uranium; high conversion ratio; long fuel life; natural convection for heat transfer; production of superheated steam; a high power output; a limited size of pressure tank; fueI handling without use of Iarge pressure lid; and moderator control. Three different typcs of power reactors are prcsented; a natural uranium, boiling heavy water reactor with forced clrculation; a boiling reactor with natural convcction and sIightly enriched fueI; and two heavy water boiling and superheating reactors using slightly enriched fuel and natural conveetion. A chapter on sumarized operating dath indicates the degree of success achieved In meetIng the objectives. (D.E.B.)
