US 2,872,401 JACKETED FUEL ELEMENT – Wigner, E. P.;
Szilard, L.; Creutz, E. C.; Feb 3, 1959 (to the U.S. Atomic Energy Commission)
These fuel elements are comprised of a homogeneous metallic uranium body completely
enclosed and sealed in an aluminum cover. The uranium body and aluminum cover
are bonded together by a layer of zinc located between them. The bonding layer
serves to improve transfer of heat, provides an additional protection against
corrosion of the uranium by the coolant, and also localizes any possible corrosion
by preventing travel of corrosive material along the surface of the fuel element.
US 2,873,243 MEANS FOR SHIELDING AND COOLING REACTORS – Wigner, E. P.; Ohlinger, L. A.; Young, G. J.; Weinberg, A. M.; Feb 10, 1959 (to the U.S. Atomic Energy Commission)
Reactors of the water-cooled type and a means for shielding such a reactor
to protect operating personnel from harmful radiation are discussed. In this
reactor coolant tubes which contain the fissionable material extend vertically
through a mass of moderator. Liquid coolant enters through the bottom of the
coolant tubes and passes upwardly over the fissionable material. A shield tank
is disposed over the top of the reactor and communicates through its bottom
with the upper end of the coolant tubes. A hydrocarbon shielding fluid floats
on the coolant within the shield tank. With this arrangement the upper face
of the reactor can be opened to the atmosphere through the two superimposed
liquid layers. A principal feature of the invention is that, in the event radioactive
fission products enter the coolant stream, imposed layer of hydrocarbon reduces
the intense radioactivity introduced into the layer over the reactors and permits
removal of the offending fuel material by personnel shielded by the uncontaminated
hydrocarbon layer. US 2,874,307 REACTOR SHIELD – Wigner, E. P.; Ohlinger, L. E.; Young, G. J.; Weinberg, A. M.; Feb 17, 1959 (to the U.S. Atomic Energy Commission)
Radiation shield construction is described for a nuclear reactor. The shield
is comprised of a plurality of steel plates arranged in parallel spaced relationship
within a peripheral shell. Reactor coolant inlet tubes extend at right angles
through the plates and baffles are arranged between the plates at right angles
thereto and extend between the tubes to create a series of zigzag channels
between the plates for the circulation of coolant fluid through the shield.
The shield may be divided into two main sections; an inner section adjacent
the reactor container and an outer section spaced therefrom. Coolant through
the first section may be circulated at a faster rate than coolant circulated
through the outer section since the area closest to the reactor container is
at a higher temperature and is more radioactive. The two sections may have
separate cooling systems to prevent the coolant in the outer section from mixing
with the more contaminated coolant in the inner section. US 2,886,503 JACKETED FUEL ELEMENTS FOR GRAPHITE MODERATED REACTORS – Szilard, L.; Wigner, E. P.; Creutz, E. C.; May 12, 1959 (to the U.S. Atomic Energy Commission)
Fuel elements for a heterogeneous, fluid cooled, graphite moderated reactor
are described. The fuel elements are comprised of a body of natural uranium
hermetically sealed in a jacket of corrosion resistant material. The jacket,
which may be aluminum or some other material which is non-fissionable and of
a type having a low neutron capture cross-section, acts as a barrier between
the fissioning isotope and the coolant or moderator or both. The jacket minimizes
the tendency of the moderator and coolant to become radioactive and/or contaminated
by fission fragments from the fissioning isotope. US 2,890,158 NEUTRONIC REACTOR – Ohlinger, L. A.; Wigner, E. P.; Weinberg, A. M.; Young, G. J.; Jun 1, 1959 (to the U.S. Atomic Energy Commission)
A means of cooling reactor fuel as it is discharged from the reactor is described.
(T.R.H.) US 2,910,418 NEUTRONIC REACTOR – Creutz, E. C.; Ohlinger, L. A.; Weinberg, A. M.; Wigner, E. P.; Young, G. J.; Oct 27, 1959 (to the U.S. Atomic Energy Commission)
A reactor cooled by water, biphenyl, helium, or other fluid with provision
made for replacing the fuel rods with the highest plutonium and fission product
content without disassembling the entire core and for promptly cooling the
rods after their replacement in order to prevent build-up of heat from fission
product activity is described. US 2,928,781 A COOLED NEUTRONIC REACTOR – Wigner, E. P.; Creutz, E. C.; Mar 15, 1960 (to the U.S. Atomic Energy Commission)
A nuclear reactor comprising a pair of graphite blocks separated by an air
gap is described. Each of the blocks contains a plurality of channels extending
from the gap through the block with a plurality of fuel elements being located
in the channels. Means are provided for introducing air into the gap between
the graphite blocks and for exhausting the air from the ends of the channels
opposite the gap. US 2,954,335 NEUTRONIC REACTOR – Wigner, E. P.; Sep 27, 1960 (to the U.S. Atomic Energy Commission)
A unit assembly is described for a neutronic reactor comprising a tube and
plurality of spaced parallel sandwiches in the tube extending lengthwise thereof,
each sandwich including a middle plate having a central opening for plutonium
and other openings for fertile material at opposite ends of the plate. US 2,961,392 NEUTRONIC REACTORS – Wigner, E. P.; Nov 22, 1960 (to the U.S. Atomic Energy Commission)
A nuclear reactor is described wherein horizontal rods of thermal-neutron-fissionable
material are disposed in a body of heavy water and extend through and are supported
by spaced parallel walls of graphite.
