Description

The present fine control system for pressurized water reactors (the so-called ''A'' mode) cannot meet the requirements of a variable output in all respects. For this reason specialists are now developing a new fine control system, called gray mode control which is better suited to rapid load variations. The basic principles for control of pressurized water reactors are summarized and, then gray mode control or the device with added manoeuvrability is described. The series of tests carried out in 1981 and 1982 on stage 3 of the Tricastin power station are analyzed and the satisfactory results obtained are presented

Abstract (French)

L'actuel systeme de pilotage des reacteurs nucleaires a eau sous pression (dit ''mode A'') n'est pas totalement en mesure de se plier aux exigences du regime de puissance variable. C'est pourquoi les specialistes mettent actuellement au point un nouveau type de pilotage (dit ''mode gris'') plus propice aux variations de charge rapides. Apres avoir rappele les principes de base du pilotage des reacteurs a eau sous pression, on decrit le pilotage mode gris, ou dispositif a manoeuvrabilite accrue, on analyse les campagnes d'essais effectuees en 1981 et 1982 sur la tranche no.3 de la centrale du Tricastin et en souligne les resultats satisfaisants
