STRUCTURAL MATERIALS

3.3.1 Displacement of Atoms The neutron irradiation to which the materials in the reactor are sub­ject alters their properties in several ways. The most important effects on the structural materials are to increase hardness and decrease ductility, to enhance creep rates at low temperatures, and, most import­ant, to reduce the density. These phenomena have to be taken into account in […]

Accuracy and Experimental Checks

Multigroup diffusion calculations can normally be expected to predict the reactivity of a system within about 0.5% and the distribution of power within about 4% throughout most of the core and within 6% close to control rods or the edge of the core. The errors are due partly to uncertainties in the basic cross-section data and partly to the approximations […]
