A zirconia-based fuel is studied for use of plutonium in light water reactors. Among the relevant properties for a nuclear fuel, efficient retention of fission products is required since the fuel matrix constitutes the first barrier against fission product ...
A detailed three-dimensional, continuous-energy MCNP4B model of the LWR-PROTEUS critical facility has been developed for the analysis of whole-reactor characteristics using ENDF/B-V, ENDF/B-VI and JEF-2.2 cross-section sets. The model has been applied to t ...
The magnetic field dependence of the thermoelectrical power of a series of Co/Cu multilayered nanowires grown by electrodeposition in a polymer matrix is almost that predicted by the Mott formula in the temperature range of 15300 K. Application of the two- ...
With a view towards developing a method for molecular laser isotope separation (MLIS) of carbon, silicon and nitrogen, this work investigated the overtone pre-excitation - infrared multiple photon dissociation (OP-IRMPD) of CF3H, SiHCl3 and NH3. The study ...
A numerical benchmark exercise has been under way for comparing the results of different calculational methods/data sets used for the analysis of light water reactor (LWR) configurations employing Pu inert matrix fuels (IMFs). The first phase of the exerci ...
Scientific conference paper We report thermopower and electrical resistance measurements of the high-temperature superconductor Bi2Sr2Ca1-xPrxCu2O8+delta (0 < x < 1) in a wide temperature range from 600 K to superconducting transition temperature (critical ...
As part of PSI's validatory efforts for neutronics calculations pertaining to inert matrix fuel (IMF) deployment in light water reactors, first-of-their-kind integral measurements have been carried out at the PROTEUS facility employing a specially fabricat ...
Zirconium is employed as the 'inert' component in several different inert matrix fuel concepts currently under development (cermet, oxide solution, etc.). Relative to the situation in standard light water reactors, this implies a very significant increase ...
The structure of the antiphase domain boundaries of strontium titanate SrTiO3 that exist at temperatures below the antiferrodistortive transition, is analyzed. It is found that some boundaries are similar to Neel domain walls, as an additional component of ...
Quasicrystals exhibit low thermal and moderate electrical conductivity, accompanied by a relatively high absolute magnitude of thermopower, which makes them suitable candidates for use as thermoelectric devices. Theoretical explanations of electrical and t ...
