Description

The aim of this article is to demonstrate, by means of a theoretical study followed by actual measurements, that it is possible to produce radiographs with partial beaconing of the machine room of an EDF nuclear power plant, by implementing optimisation tools in order to reduce to a reasonable minimum the exposure to ionising radiation of public personnel working at the limit of this partial beaconing

Abstract (French)

Cet article a pour but de demontrer par une etude theorique suivie de mesures reelles qu'il est possible de realiser des radiographies avec un balisage partiel de la salle des machines d'une centrale nucleaire EDF moyennant la mise en oeuvre d'outils d'optimisation afin de reduire au minimum raisonable l'exposition aux rayonnements ionisants du personnel public travaillant a la limite de ce balisage partiel
