Abstract: An emergency core coolant system for cooling the nuclear core of a nuclear reactor. A storage tank having a supply of coolant fluid therein is positioned outside of the reactor vessel and communicates through conduit means to an inactive plenum within the reactor vessel. Two distribution means are provided within the reactor vessel to flow couple the inactive plenum to the nuclear core, the two distribution means communicating with the inactive plenum at two different vertical elevations. Normally closed valve means is interposed in the conduit means and is operable to be opened in the event of an emergency to introduce coolant fluid in the tank means into the inactive plenum. The coolant fluid in the inactive plenum is then distributed to the nuclear core by the two distribution means.

Abstract: A guide structure for aligning fuel assemblies forming a nuclear core of a nuclear reactor and for guiding a plurality of control elements for telescoping movement within guide channels of fuel assemblies. Two spaced tube sheets, rigidly connected by a plurality of hollow tubes extending therebetween, are supported by a support means relative to the nuclear core with each of the hollow tubes being in alignment with a guide channel of the fuel assemblies. A plurality of yoke means, each of which interconnects at least two of a plurality of control elements situated within some of the hollow tubes, are provided whereby the interconnected control elments telescopingly move as a unit within the guide channels.
