TRANSPORT CALCULATIONS FOR PROTON SHIELDING [PDF]
The dose rate and integrated dose, inside a shield, due to an arbitrary proton flux was calculated. To this end, it was necessary to ascertain the effect of the shield on the incident flux. This aspect of the problem is considered. The analysis takes into account both proton ionization energy loss and secondary-particle production, using the transport ...

Self-Shielding Treatment to Perform Cell Calculation for Seed Furl In Th/U Pwr Using Dragon Code
Time and precision of the results are the most important factors in any code used for nuclear calculations. Despite of the high accuracy of Monte Carlo codes, MCNP and Serpent, in many cases their relatively long computational time leads to difficulties ...
