Radioactive Contamination Near Natural Uranium - Graphite - Gas Reactors

  • 1. CEA, Centre de Production de Plutonium de Marcoule (France)

Description

The authors give the results of numerous assessments of contamination in connection with reactors in operation during maintenance; reactors shut down during overhaul and repair work (coolants, exchangers, interior of the tank, etc.) ; and accidents in the cooling circuit and ruptured cladding. They show that, except in special cases, it is mainly activation products that predominate. Moreover, after eight years of operation the points where contamination likely to give considerable dose rates accumulates remain very localized, and there has been no need to reinforce personnel protection measures.

Abstract (French)

Le mémoire donne les résultats de nombreuses évaluations de la contamination effectuées, soit pendant la marche des piles lors des opérations d'entretien, soit pendant l'arrêt des piles au cours des travaux de revision et de réparation (réfrigérants, échangeurs, intérieur du caisson, etc. ), soit à la suite d'incidents sur le circuit de refroidissement et de ruptures de gaine. Ils montrent que, sauf dans des cas particuliers, ce sont essentiellement les produits ď activation qui dominent. Par ailleurs, après huit ans de fonctionnement, les points d'accumulation de la contamination susceptibles de délivrer des débits de dose importants restent très localisés et les moyens de protection individuels utilisés n'ont pas dû être renforcés.
