Posiva Oy is preparing to submit an operating licence application for a spent nuclear fuel geologic repository located at Olkiluoto, Finland. The construction licence for the underground disposal facility and encapsulation plant was granted in 2015 and construction of the disposal facility began in December 2016. Safe disposal is achieved by the KBS‐3 concept, developed in collaboration with Posiva's Swedish counterpart, the Swedish Nuclear Fuel and Waste Management Co, (SKB). The KBS‐3 concept consists of disposal canisters (a cast iron insert and a copper overpack), surrounded by swelling bentonite and disposed in crystalline bedrock. The copper overpack ensures containment of radioactive materials and its performance against corrosion is a key driver for the design of the engineered barrier system and the repository overall. This paper describes the current status of the Posiva programme, recent learnings from the construction of the repository, and the implications for the long‐term performance of the canister.

芬兰乏燃料地质处置库计划的状态报告和正在进行的腐蚀研究

Posiva Oy正在准备为位于芬兰Olkiluoto的乏核燃料地质处置库提交操作许可证申请。地下处置设施和封装厂的建设许可证于2015年获得批准，处置设施的建设于2016年12月开始。通过与Posiva瑞典同行，瑞典核燃料公司和瑞典石油公司合作开发的KBS-3概念实现了安全处置。废物管理公司（SKB）。KBS-3概念由处理罐（铸铁插件和铜外包装）组成，被膨胀的膨润土包围并置于结晶基岩中。铜外包装可确保容纳放射性物质，其抗腐蚀性能是设计屏障系统和整个储存库的关键驱动力。
