Computation of a crack-free absorber material
Description
From a computation of the thermal stress field as a function of most important parameters (pin diameter, boron carbide grain size, pellet density) a design emerges in which pellets do not crack under irradiation, avoiding fragment wedging. Rod tube inner diameter and 10B content per unit length being specified, as data of the problem, the calculations are performed in two steps: selection of geometry (number of pins and pin diameter), and determination of density and grain size after geometry has been selected
