METHOD FOR DETERMINING A THRESHOLD VALUE OF A NUCLEAR REACTOR OPERATING PARAMETER, CORRESPONDING SYSTEM, COMPUTER PROGRAMME AND SUPPORT

摘要

The process, carried out by a computer programme, comprises stages in which a transient function in the nuclear reactor's performance is simulated and used to calculate the value reached on a physical scale during a transient function in the sleeve (33) of a reactor core fuel pencil (24). The calculated value is used to determine a physical dimension corresponding to a rupture in the pencil sleeve caused by stresses or deformation energy density.
