摘要
本文探讨了国外运行的铀-石墨堆(GLEEP, WAGR, BGRR, HTGR)和石墨反射器堆(DIORIT, DR 1)中石墨去除的最佳实践。基于几个案例研究，它考虑了不同的方法，特别是:石墨破碎;水下堆堆井筒淹水拆除及上部生物屏蔽拆除拆卸上部生物屏蔽层，逐层去除石墨块。它讨论了在国际项目下实际执行先进办法的当前趋势、现有挑战和长期计划。
Graphite Removal from Uranium-Graphite Reactors: International Experience and Approaches
The article explores the best practices for graphite removal from the stacks of uranium-graphite reactors (GLEEP, WAGR, BGRR, HTGR) and reactors with graphite reflectors (DIORIT, DR 1) operated abroad. Based on several case studies, it considers different approaches, in particular: graphite crushing; underwater stack demolition by reactor shaft flooding and upper biological shield dismantling; dismantlement of the upper biological shield and layer-bylayer graphite block removal. It discusses current trends, existing challenges and long-term plans for the practical implementation of advanced approaches under international projects.
