Knights, H C

A simple and reliable restraint for a moderator and reflector structure suitable for use in a nuclear reactor built into a moving body is described. The restraint may also be used with a graphite moderator structure in which the blocks are unspaced from one another. The restraint consists of rings of restraint shoes around the structure providing a radially acting restraint force and torque tubes for loading the shoes against the structure. The shoes are loaded by lever arms attached to the torque tubes and all arms are connected together to rotate in unison. The device also contains means for relaxing the load in the torque tubes when the load exceeds a predetermined amount, by a degree sufficient to ensure that adequate static loading of the moderator structure is maintained. The load is relaxed by deformable members of the torque tubes which allow the untwisting of the torque tubes and a stop is pro- vided such that the untwisting will stop when the amount of unloading necessary to maintain the static moderator is met.
