Abstract

Abstract The standard design for the underground disposal of high-level nuclear waste consists of a carbon steel container that hosts the waste shielded by a 5-cm-thick layer of corrosion-resistant...

Summary

Introduction

There are three high-level nuclear waste repositories under construction Both the Forsmark granite project in Sweden and the Olkiluoto granite project in Finland are in an advanced stage of licensing. These two projects (SKB 2006; POSIVA 2006) and the former Columbia River Basalt (CRB) project in the USA (Lutton et al 1986) envisage the storage of waste in copper-shielded steel containers surrounded by a bentonite buffer. The Bure clay project in France is in an early stage of licensing The design of this project is exceptional in that it exclusively considers unshielded steel containers implying very high corrosion rates (ANDRA 2016). The final design may change in the course of the licensing procedure
