怎样有效而又安全地拆除使用寿命业已结束的原子核反应堆?这是当前需要紧迫解决的问题。许多国家在国际原子能委员会在支持下打算齐心协力作好废堆的拆除工作。现在在加拿大、意大利和西德已经分别进行了对使用重水慢化的Gentilly1号反应堆、Garigliano BWP及Lingen BWR反应堆拆除的第一期工程。西德还计划全部拆除气体慢化的Niederaichbach反应堆。 How to effectively and safely demolish an end-of-life nuclear reactor? This is an issue that needs to be urgently solved. Many countries, with the support of the International Atomic Energy Commission, intend to make concerted efforts to demolish the heap. The first phase of the dismantling of Gentilly 1 reactors, Garigliano BWP and Lingen BWR, which use heavy water, has now been conducted in Canada, Italy and West Germany. West Germany also plans to demolish the gas-moderated Niederaichbach reactor.
