Conference Article: Dismantling strategy for secondary loops and associated sodium circuits

Joulia, E. (Electricite de France/CIDEN (EDF/CIDEN), Villeurbanne (France))

Abstract

This document describes the operations to be performed to dismantle the secondary and auxiliary circuits on the Creys-Malville power station. The period covers the disposal of these circuits, from their post-operation status, i.e., secondary sodium drained and circuits maintained under a neutral gas, until complete dismantling of the installations. The problems involved in sodium circuit treatment are more specifically described, and notably the preliminary interventions to materially separate the 'secondary' zones from the 'primary-reactor' zones and to prepare for the treatment of the residual sodium.
