it had to bemeaningful. Adding the number of spheres in the first, second and third layer of spheres around a nucleus sphere (12 + 42 + 92) yields 146 spheres. This is the number of neutrons in the element uranium. Add 92 to 146 to yield 238, the number...
The new element was found when uranium, atomic number 92, was bombarded with neutrons; it is radioactive, with a half-period of about 13 minutes. This announcement would appear to be a sequel to the experiments reported by Prof. Fermi in NATUEE of May 19, p. 757, when he described ...
The escaping neutrons are absorbed by the surrounding liquid where they breed T, which is then chemically bound, and produce heat. The heat, radiation and mechanical shock are absorbed in the liquid which flows through a heat exchanger in order to energize the associated turbogenerator power ...
Fast Neutron Reactors.Unlike conventional reactors, FNRs allow neutrons to travel fast through the reaction chamber. This potentially increases the efficiency of fuel, and increases what the industry calls fuel "burn-up." Fuel lasts much longer in an FNR than it does in a conventional reactors. ...
This leads us to believe that maybe the noncosmogenic He-3 isn’t magmatic, but was produced post-emplacement by the reaction Li-6(n,alpha)He-3 induced by neutrons derived from decay of U and Th in the rock. Helen Margerison did this calculation with a few trial measurements and came ...
** Graphite is used to slow neutrons in epithermal designs, and deteriorates in a high neutron flux environment. The rate of damage increases with temperature, which is a particular problem with MSRs at 700°C. In liquid-fuel MSR designs the fission products dissolve in the fuel salt and ar...
