EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 78 / 257 This container can be manufactured from metals contaminated with low levels of activity, allowing recycling of metals which would otherwise have to be disposed of as radioactive waste. The cask outer dimensions of 1500 mm height, and 1060 mm diameter are fixed but the internal and lid configurations can be adapted to the needs of different waste streams. Typical empty weights can be between 4000 kg and 9400 kg providing volumes between 135 l and 680 l. (This description is based on the MOSAIK Type II container which has been subject to the concept stage LoC NDA assessment.) A key advantage of the use of this container is the accessibility of the container during processing, handling and storage due to the shielding provided. This permits the use of mobile, modular conditioning systems. 7.4.3.4 ILW Package Volumes FIGURE 21: MOSAIK CAST IRON CONTAINER The AREVA waste packaging technology, including the use of cast iron containers, differs from the procedures generally adopted with the UK nuclear industry. Table 16 and Figure 22 compares some aspects of the two approaches and shows that the AREVA concept could expect to produce a much lower volume of waste. The AREVA concept design technology will be further developed and will be assessed by UK regulatory authorities. If the design meets the requirements of these regulators (in terms of safety and environmental performance) then the packaging technology will be proposed for the UK EPR waste treatment facilities.
