| Abstract: | The paper solves an optimization problem concerning the conditioned minimization of fuel feed rate against a control vector which incorporates both zonal irradiation and the configuration of an adjusting rod system. One starts from a reference core with two irradiation zones of which the first contains 188 channels and for which all control devices and parasitic absorbers are taken into account. The fuel feed rate is minimized subject to four restrictions imposed, namely reactivity to equilibrium, maximum channel and bundle powers and reactivity of an adjusting rod system. The codes FMDP and LPROG are used to solve this problem. |
