Popis: Comparatively simple relationships for estimating the burn-up are proposed; they are of acceptable accuracy and allow for the distortion of the neutron field with height under steady conditions as a result of burn-up and boiling of the coolant. To refine these estimates and also to calculate the neutron field itself, the isotopic content of the discharged fuel and a whole string of other parameters are used on a simple and effective method of numerical computation which is described. The time to compute the burn-up, the energy distribution, the isotopic composition of the depleted fuel, and other reactor characteristics amounts in all to a few seconds.
