Abstract
The present invention relates to a method for assisting in the operation of a nuclear reactor, which comprises the steps of: establishing a request using a man/machine interface (31) interacting with a dedicated operation assistance computer (32) and using a three-dimensional neutron computation code (32a) solving the diffusion equation, referred to as the operation assistance code; unidirectionally transmitting, from a system (10) for monitoring the operation of the reactor core to said operation assistance computer (32), a set of data (13) which are representative of the hardware, geometric, and neutron characteristics of the core, as well as the operating conditions of the core, said data (13) being determined by a three-dimensional neutron code (12) updating the isotope balance of the core during fuel depletion and periodically solving the diffusion equation online, referred to as the monitoring code, said monitoring code (12) being installed on a second separate computer, referred to as the monitoring computer, which is dedicated to said monitoring system (10); determining a change in the behavior of the reactor core using said operation assistance code (32a), said representative) data (13) being used as input data for said operation assistance code (32a).
