核废料必须以不会对环境或人类健康造成重大影响的方式存放。在某些情况下，储存库的完整性需要维持数十年甚至数十万年。为了确保这种密封，核废料经常被转换成非常耐用的玻璃。然而，仅仅根据短期试验来保证这种遏制的有效性是根本困难的。到目前为止，一些人为和天然火山玻璃已被调查用于此目的。然而，由古代文化生产的用于连接石墙中的岩石的玻璃尚未被利用，尽管它们可能提供对玻璃在自然环境中的长期耐久性的重要见解。因此，一个项目正在启动，其范围是获得样品和表征其环境，以及使用一套先进的材料表征技术对其进行研究。它将被分析hillfort玻璃可能是如何制备的，以及在现场条件下它们发生了多大程度的变化。最终目标是更好地了解核废料玻璃的蚀变行为及其成分依赖性，从而改进和验证核废料玻璃腐蚀模型。本文涉及项目的规划和启动，并提出了一些早期的调查结果的融合角闪岩和加入的花岗岩石在hillfort walls.Keywords：老化，角闪岩，模拟，人为，Broborg，玻璃，hillfort，hill-fort，沥滤，长寿，核，壁垒，废物的过程。
Nuclear waste must be deposited in such a manner that it does not cause significant impact on theenvironment or human health. In some cases, the integrity of the repositories will need to sustain fortens to hundreds of thousands of years. In order to ensure such containment, nuclear waste is frequentlyconverted into a very durable glass. It is fundamentally difficult, however, to assure the validity ofsuch containment based on short-term tests alone. To date, some anthropogenic and natural volcanicglasses have been investigated for this purpose. However, glasses produced by ancient cultures for thepurpose of joining rocks in stonewalls have not yet been utilised in spite of the fact that they might offersignificant insight into the long-term durability of glasses in natural environments. Therefore, a projectis being initiated with the scope of obtaining samples and characterising their environment, as well asto investigate them using a suite of advanced materials characterisation techniques. It will be analysedhow the hillfort glasses may have been prepared, and to what extent they have altered under in-situconditions. The ultimate goals are to obtain a better understanding of the alteration behaviour of nuclearwaste glasses and its compositional dependence, and thus to improve and validate models for nuclearwaste glass corrosion. The paper deals with project planning and initiation, and also presents some earlyfindings on fusion of amphibolite and on the process for joining the granite stones in the hillfort walls.Keywords: ageing, amphibolite, analogue, anthropogenic, Broborg, glass, hillfort, hill-fort, leaching,long-lived, nuclear, rampart, waste.
