Measurements and Monte-Carlo simulations of the particle self-shielding effect of B4C grains in neutron shielding concrete

, 2018
A combined measurement and Monte-Carlo simulation study was carried out in order to characterize the particle self-shielding effect of B4C grains in neutron shielding concrete. Several batches of a specialized neutron shielding concrete, with varying B4C

Non-classical transport with angular-dependent path-length distributions. 2: Application to pebble bed reactor cores

, 2013
We describe an analysis of neutron transport in the interior of model pebble bed reactor (PBR) cores, considering both crystal and random pebble arrangements.

Reactor moderator, pressure vessel, and heat rejection system of an open-cycle gas core nuclear rocket concept [PDF]

A preliminary design study of a conceptual 6000-megawatt open-cycle gas-core nuclear rocket engine system was made. The engine has a thrust of 196,600 newtons (44,200 lb) and a specific impulse of 4400 seconds.

Optimized 4 pi spherical shell depleted uranium-water shield weights for 200 to 550-megawatt reactors [PDF]

Optimization calculations to determine minimum 4 pi spherical-shell weights were performed at 200-, 375-, and 550-megawatt-thermal reactor power levels. Monte Carlo analyses were performed for a reactor power level corresponding to 375 megawatts.
