Method and system for selecting a loading pattern for a nuclear reactor core, corresponding computer program and program support

摘要

The method involves providing fabrication data relative to nuclear fuel assemblies (16), and providing neutronics data representing previous exploitation and future exploitation of a nuclear reactor core (1) during exploitation cycle. A three-dimensional distribution of local power is calculated in the core during the future exploitation. Extreme values attained by a thermomechanical parameter are calculated within the assemblies using thermomechanical computation software such as Copernic software. A loading pattern is selected among loading patterns based on the calculated extreme values. Independent claims are also included for the following: (1) a system for selecting a loading pattern of a nuclear reactor core (2) a computer program comprising set of instructions for executing a method for selecting a loading pattern of a nuclear reactor core (3) a medium for storing program to execute the method for selecting a loading pattern of a nuclear reactor core.
