Abstract

A reactor of the type which preferably uses plutonium as the fuel and a liquid moderator, preferably ordinary water, and which produces steam within the reactor core due to the heat of the chain reaction is described. In the reactor shown the fuel elements are essentially in the form of trays and are ventically stacked in spaced relationship. The water moderator is continuously supplied to the trays to maintain a constant level on the upper surfaces of the fuel element as it is continually evaporated by the heat. The steam passes out through the spaces between the fuel elements and is drawn off at the top of the core. The fuel elements are clad in aluminum to prevent deterioration thereof with consequent contamimation of the water.

SAFETY DEVICE FOR NEUTRONIC REACTOR

Patent Spillmann, W.

A device is designed for the automatic stopping of a gascooled reactor by the release of a neutron-absorbent gas into the reactor. The device comprises an enclosed vessel filled with the neutron-absorbent gas and located in the central outlet space of the reactor, and at least one pipe leading from thc vessel into the annular inlet space. The mouth of the pipe is closed with a closure member which opens when the vessel pressure exceeds a predetermined pressure. Thus, in the operation of the device, the neutronabsorbent gas is released into the incoming coolant and not into the outgoing coolant.more » (D.L.C.)« less
Neutronic Reactor Design to Reduce Neutron Loss

Patent Miles, F. T.

A nuclear reactor construction is described in which an unmoderated layer of the fissionable material is inserted between the moderated portion of the reactor core and the core container steel wall. The wall is surrounded by successive layers of pure fertile material and moderator containing fertile material. The unmoderated layer of the fissionable material will insure that a greater portion of fast neutrons will pass through the steel wall than would thermal neutrons. Since the steel has a smaller capture cross section for the fast neutrons, greater nunnbers of neutrons will pass into the blanket, thereby increasing the over-all efficiencymore » of the reactor.

NEUTRONIC REACTOR STRUCTURE

Patent Weinberg, A.M.; Vernon, H.C.

A neutronic reactor is described. It has a core consisting of natural uranium and heavy water and having a K-factor greater than unity which is surrounded by a reflector consisting of natural uranium and ordinary water having a Kfactor less than unity.
NEUTRONIC REACTOR BURIAL ASSEMBLY

Patent Treshow, M.

A burial assembly is shown whereby an entire reactor core may be encased with lead shielding, withdrawn from the reactor site and buried. This is made possible by a five-piece interlocking arrangement that may be easily put together by remote control with no aligning of bolt holes or other such close adjustments being necessary.
