Abstract
Abstract In a liquid-cooled nuclear reactor, coolant deflectors are deployed in a pattern for deflecting the coolant into transverse flow streams which are parallel to the transverse power gradient among adjacent assemblies. In typical pressurized water reactors, these streams are concentric with respect to the intersection of adjacent nuclear fuel assemblies and are oriented so that adjacent concentric streams flow in opposite directions. This deployment of deflectors permits the operation of a reactor at a power level surprisingly higher than can be obtained from using coolant deflector deployments heretofore devised.
