Liquid metal cooled nuclear rector constructions
First Claim
1. A liquid metal cooled nuclear reactor comprising a nuclear fuel assembly housed in a coolant-containing primary vessel which is housed within a concrete containment vault and having thermal insulation interposed between the vessel and the vault, the improvement comprising:
- said thermal insulation consisting of a plurality of adjoining units, metal structure secured to and projecting from the concrete of the vault and from which each thermal insulation unit is hung, each said unit including a pack of thermal insulating material, each unit also including a contained void co-extensive with said pack, said void being situated between said pack of thermal insulating material and the concrete, and means connecting the void of each unit to the void of at least one adjoining unit so as to form continuous ducting for a fluid coolant.

Abstract
In a liquid metal cooled nuclear reactor with a nuclear fuel assembly in a coolant-containing primary vessel housed within a concrete containment vault, there is thermal insulation to protect the concrete, the insulation being disposed between vessel and concrete and being hung from metal structure secured to and projecting from the concrete, the insulation consisting of a plurality of adjoining units each unit incorporating a pack of thermal insulating material and defining a contained void co-extensive with said pack and situated between pack and concrete, the void of each unit being connected to the voids of adjoining units so as to form continuous ducting for a fluid coolant.
