Description

One measure to improve fuel utilization in light water reactors is to increase the conversion ratio in a tight, hexagonal PuO2/UO2 mixed oxide fuel pin lattice. The PWHCR (pressurized water high converter reactor) is the Siemens/KWU approach towards this kind of tight lattice reactor, with the main characteristics of the actual concept being zirconium-clad fuel rods and an average moderator-to-fuel volume ratio of 1.2. In a recent study, concerning the nuclear core design for the PWHCR, mainly the questions related to the fuel assembly design, the reactivity control system and fuel management strategies have been addressed. Results of the investigations essentially confirmed the concept of the tight lattice PWR to be technically feasible. (author). 5 refs, 8 figs, 4 tabs
