Only three processes, operant during the formation of the Solar System, are responsible for the diversity of matter in the Solar System and are directly responsible for planetary internal-structures, including planetocentric nuclear fission reactors, and for dynamical processes, including and especially, geodynamics. These processes are: (i) Low-pressure, low-temperature condensation from solar...
Ethics requires good science. Many scientists, government leaders, and industry representatives support tripling of global-nuclear-energy capacity on the grounds that nuclear fission is "carbon free" and "releases no greenhouse gases." However, such claims are scientifically questionable (and thus likely to lead to ethically questionable energy choices) for at least 3 reasons. (i) They rely on ...
Three electrolysis cells with built-in ultrasonic transmitters were developed by Energetics Technologies. The ultrasonic transmitters induce cavitation in the electrolyte in the vicinity of the palladium cathode for in-situ cleaning and activation of the cathode surface, generation of dislocations, assistance in loading and excitation of the Pd-D system. The ultrasonically assisted electrolysis...
It is difficult to reveal smuggled U-bearing material by passive gamma-detection, because the weak radiation can easily be shielded. Neutrons, as penetrate shielding, represent a detection potential, by inducing fission in the nuclear material. A 4 MeV linear accelerator was used as a pulsed neutron source for active interrogation of U-bearing material. Produced in heavy water by bremsstrahlung...
Background: Uranium poses both chemical and radiological hazard to the living system. Drinking water from river is one of the major sources of uranium intake. Dissolution of minerals, washout from rain water, rock-water interaction, agricultural run off, and industrial disposals are some of the sources of uranium in river water system. Present study was aimed to determine the uranium in the wat...
An assessment of the potential biological hazard radioactive waste in deep disposals after reprocessing spent nuclear fuel thermal and fast reactors two-component power has been carried out. It is shown that when 0.1% fissile materials, minor actinides particular fractions fission products are transferred to with same contribution generated electricity time radiation-migration equivalence occur...
