In reactor physics, the concept of buckling is used to describe the relationship between requirements on fissile material inside a reactor core and the dimensions and shape of that core. In general, criticality is achieved when the neutron production rate is equal to the rate of neutron losses, … See more The basic classification of states of a reactor is according to the multiplication factor as eigenvalue which is a measure of the change in the … See more Let assume a bare square cylinder (i.e., height = diameter; H = 2R). Assume that the material bucklingof this reactor, which is given using one-group cross sections, is: Calculate the … See more Adding a reflector to a reactor allows either the volume of the reactor or the requirements on fuel to be reduced, or some combination of the two. If the reflector savings is … See more WebThe linear power rating represents the power produced per unit length (watts/em) by a fuel element. This expression can be shown to be given by the integration of the thermal conductivity of the fuel, k(T), over the temperature from the fuel surface, Ts• to the centre of the fuel t Tc. That is, Linear power rating =fTek(TldT (Watts/em) • (8 ...
