A design concept for a small nuclear reactor for neutron transmutation doping silicon (NTD-Si) using a Pressurized Water Reactor (PWR) full-length fuel assembly was proposed in our previous work. The excess reactivity was suppressed by a combination of Gd2O3 and soluble boron, which results in...

The approximate radius of a neutron is 1.5 x 10-15 m, and the mass is 1.675 x 10-27 kg. Calculate the density of a neutron. V = (4/3)pir3 for a sphere. The total mass that can be lifted by a balloon is given by the difference between the mass of air displaced by the balloo...
The energy of a particle in an atom varies with the variation in the mass as well as the diameter of nucleus. When the mass and diameter of the nucleus increase, then the energy of particle decreases. Mathematically, the energy of a particle is, ...
Comparison of residual strains in the inner sheet along the radial position predicted by the numerical method and neutron diffraction after unloading the 53.38 kN squeeze force. (A) Radial strain, (B) Hoop strain, and (C) Clamping strain. Large squeeze forces induced big rivet driven head ...

A facility for instrumental neutron activation analysis (INAA) of large samples (up to 1 m long and 15 cm diameter) has been built. Correction methods for the simultaneous occurrence of neutron self-shielding and gamma-ray self-attenuation effects have been implemented and tested with a variety...
within which a teleflex cable carrying a neutron-flux sensor at its end is moved along, in order to carry out flux measurements over the entire height of the assembly while the reactor is in operation. Such measurements can thus be made over the entire height of the core in the region of...
