Abstract
An integrated head package for a nuclear reactor has a pressure vessel closure head with control rod drive mechanisms thereon enclosed in a shroud, and a plurality of vertical lift rods secured to the vessel head with a missile shield plate extrending between the lift rods and vertically slidably retained between spaced stop members adjacent the upper ends of the lift rods. A lift rig is secured to the missile shield plate, preferably through attachment to support blocks secured to the upper surface of the plate. Impact forces of a missile against the lower surface of the missile shield plate are transferred to a lifting force and are not transferred to the lifting rods, head lugs, closure studs and pressure vessel supports.
