Fasteners for nuclear reactor systems
Various embodiments are directed towards a nuclear latch assembly. The assembly includes a latch housing and a latch mechanism. The latch mechanism includes a projection member. The latch mechanism provides a biasing force on the projection member. Unless an opposing force on the projection member counterbalances the biasing force, the projection member at least partially projects from a surface of the latch housing. The assembly may include a biasing member that provides the biasing force on the projection member. The assembly may include a bolt. The bolt includes a longitudinal axis. A bore included in the housing is sized to receive the bolt. When the bore receives the bolt, the housing is rotatable about the longitudinal axis of the bolt. The latch mechanism includes a side bore that receives the projection member, the biasing member, and a disk intermediate the projection member and the biasing member.
