Blaushild, R M; Veronesi, L

A nuclear reactor is described comprising: a reactor pressure vessel, having a vertically oriented cylindrical tubular shell portion, the bottom of which is closed by a hemispherical shell portion having upper sidewalls; a core barrel disposed internally within the reactor pressure vessel; means mounted upon the reactor pressure vessel for engaging the periphery of the core barrel, comprising a crossbeam member, and a pair of brackets connected to the opposite ends of the crossbeam member. The pair of brackets extend radially outwardly of the crossbeam member and engage the reactor pressure vessel at the upper sidewalls of the hemispherical shell portion so as to radially space the crossbeam member from the reactor pressure vessel; recess means defined within the crossbeam member of the engaging means; key means secured to the core barrel and disposed within the recess means; and vertically oriented channel means defined within the confines of the crossbeam member and the brackets of the engaging means for providing a vertically directed fluid conduit for coolant flow through the engaging means.
