ABSTRACT:
An emergency core cooling system for a nuclear reactor in which an emergency cooling injection manifold is integrally formed with the guide structure which guides control elements into the reactor core. The guide structure comprises two vertically spaced plates each of which substantially overlies the entire core and which are interconnected by a control element guidance means. A third plate is supported in vertical spaced relationship from one of the plates of the guide structure to define the manifold therebetween. Means are provided for substantially sealing the plenum from the main coolant flow path of the reactor. Means are also provided for introducing emergency coolant into the injection manifold and for dispersing coolant fluid therein into the core in the event of a loss of coolant accident.
