Description

The idea to improve the fuel utilization in LWRs by increasing the conversion ratio to a value near to one. Led to a core with a tight triangular lattice with MOX fuel in modern PWR designs. One of the main problems is to verify that the usual PWR safety criteria are kept valid in this tight lattice PWR concept (APWR). This paper describes the main characteristics of such an APWR, then deals with the calculational procedures and nuclear data sensitivities. A comparison with experiments will show the present day capabilities in calculating the nuclear characteristics of such a tight lattice advanced PWR. (orig./DG)
