AN AUTOMATED SYSTEM FOR CONTROL OF VVER-1000 FUEL PROPERTIES AT THE EXPENSE OF REACTOR POWER OPTIMIZATION
Journal Title: Вчені записки Таврійського національного університету імені В. І. Вернадського. Серія: Технічні науки - Year 2018, Vol 29, Issue 3
Abstract
Described is the use of WWER-1000 type reactor fuel rod claddings’ resource estimating method, taking into account the creeping as the main process of shell damage accumulation; this method being applied when creating an automated nuclear fuel properties control system to optimize the reactor loading regime. Revealed is the necessity of shell damage change simulation for the correct calculation of fuel rod envelopes’ stresses and deformations evolution, taking into account the complete history of reactor loading. Elaborated is the scheme of automated system for the nuclear fuel properties control by optimizing the reactor loading mode, with a detailed consideration of the suggested control system elements.
