Method and arrangement for developing core loading patterns in nuclear reactors

摘要

A method for developing core loading patterns in nuclear reactors in which a set of limits applicable to a core may be defined (S10), and a test core loading pattern design, to be used for loading the core, may be determined(S20) based on the limits. Reactor operation on at least a subset of the core may be simulated (S30) to produce a plurality of simulated results. The simulated results may be compared (S40) against the limits, and data from the comparison may indicate (S50) whether any of the limits were violated by the core during the simulation. A designer or engineer may use the data to modify the test core loading pattern, creating one or more derivative core loading pattern design(s) for simulation and eventual perfection as an acceptable core loading pattern design for the core.
