Description

The weights and thicknesses of two-layer W-- LiH shadow shields were calculated for SNAP-2, -8, and (assumed) -50 reactors. The shields are shaped as spherical sectors with haif-angles up to 30 deg and are sized so that no part of the reactor is visible within the volume subtended by the shield. Weights and thicknesses are presented for both manned and unnaanned vehicles over a wide range of reactor thermal powers, operating durations, reactorpayload separation distances, and allowable radiation dosages. The thicknesses of the W and LiH layers are optimized to provide a minimum weight shield. (auth)
