摘要： Vertical drilling of cylindrical holes in the soil, and the lining of such holes, provides storage vaults called caissons. A guarded depot is provided with a plurality of such caissons covered by shielded closures preventing radiation from penetrating through any linear gap to the atmosphere. The heat generated by the radioactive material is dissipated through the vertical liner of the well into the adjacent soil and thus to the ground surface so that most of the heat from the radioactive material is dissipated into the atmosphere in a manner involving no significant amount of biologically harmful radiation. The passive cooling of the radioactive material without reliance upon pumps, personnel, or other factor which might fail, constitutes one of the most advantageous features of this system. Moreover this system is resistant to damage from tornadoes or earthquakes.Hermetically sealed containers of radioactive material may be positioned in the caissons. Loading vehicles can travel throughout the depot to permit great flexibility of loading and unloading radioactive materials. Radioactive material can be shifted to a more closely spaced caisson after ageing sufficiently to generate much less heat. The quantity of material stored in a caisson is restricted by the average capacity for heat dissipation of the soil adjacent such caisson.
摘要翻译：土壤中圆柱孔的垂直钻孔和这些孔的衬里提供了称为沉箱的储存库。防护仓设置有多个这样的沉箱，该沉箱由屏蔽的封盖覆盖，防止辐射穿透任何与大气的线性间隙。由放射性物质产生的热量通过井的垂直内衬消散到相邻的土壤中，从而散射到地面，使得放射性物质的大部分热量以不大量的生物学方式散发到大气中有害辐射。放射性物质的被动冷却不依赖于泵，人员或可能失效的其他因素构成该系统最有利的特征之一。此外，该系统可抵御龙卷风或地震造成的损坏。放射性物质的密封容器可以放置在沉箱中。装载车辆可以穿过车库，以允许装载和卸载放射性物质的极大灵活性。在老化之后，放射性材料可以转移到更接近间隔的沉箱，以产生更少的热量。储存在沉箱中的材料的数量受到这种沉箱附近土壤的平均散热能力的限制。

摘要： A plant for the reprocessing of fuel rods for a nuclear reactor comprises a plurality of rectangular compartments desirably arranged on a rectangular grid. Signal lines, power lines, pipes, conduits for instrumentation, and other communication lines leave a compartment just below its top edges. A vehicle access zone permits overhead and/or mobile cranes to remove covers from compartments. The number of compartments is at least 25% greater than the number of compartments used in the initial design and operation of the plant. Vacant compartments are available in which replacement apparatus can be constructed. At the time of the replacement of a unit, the piping and conduits are altered to utilize the substitute equipment in the formerly vacant compartment, and it is put on stream prior to dismantling old equipment from the previous compartment. Thus the downtime for the reprocessing plant for such a changeover is less than in a traditional reprocessing plant.
摘要翻译：用于核反应堆的燃料棒的后处理设备包括多个矩形隔室，该矩形隔室理想地布置在矩形网格上。信号线，电源线，管道，仪器管道和其他通信线路将隔间留在其顶部边缘的正下方。车辆通行区允许架空和/或移动式起重机从隔间移除盖。隔室的数量比工厂初始设计和运行中使用的隔间数量大至少25％。可提供空置隔间，可在其中构建更换设备。在更换一个单元时，更换管道和管道以利用原来空置的替代设备，并在从旧隔间拆除旧设备之前投入运行。因此，这种转换的后处理厂的停机时间要小于传统的后处理厂。

摘要： In a nuclear facility such as a reprocessing plant for nuclear fuel rods, the central air cleaner discharging ventilating gas to the atmosphere must meet preselected standards not only as to the momentary concentration of radioactive components, but also as to total quantity per year. In order more satisfactorily to comply with such standards, reprocessing steps are conducted by remote control in a plurality of separate compartments. The air flow for each compartment is regulated so that the air inventory for each compartment has a slow turnover rate of more than a day but less than a year, which slow rate is conveniently designated as quasi-hermetic sealing. The air inventory in each such compartment is recirculated through a specialized processing unit adapted to cool and/or filter and/or otherwise process the gas. Stale air is withdrawn from such recirculating inventory and fresh air is injected (e.g. by the less than perfect sealing of a compartment) into such recirculating inventory so that the air turnover rate is more than a day but less than a year. The amount of air directed through the manifold and duct system from the reprocessing units to the central air cleaner is less than in reprocessing plants of conventional design.
摘要翻译：在诸如核燃料棒后处理的核设施中，向大气排放通风气体的中央空气净化器不仅要符合放射性元素的瞬时浓度的预选标准，而且必须符合每年总量的预选标准。为了更令人满意地遵循这样的标准，再处理步骤通过远程控制在多个单独的隔间中进行。每个隔室的空气流量被调节，使得每个隔间的空气库存具有超过一天但少于一年的较慢的周转率，其慢速率被方便地指定为准密封。每个这样的隔室中的空气库存通过适于冷却和/或过滤和/或以其他方式处理气体的专门的处理单元再循环。从这种循环库存中取出陈旧的空气，并且将新鲜空气注入（例如通过不太完美的隔室密封）到这种循环库存中，使得空气更换速率超过一天但少于一年。通过歧管和管道系统从再处理单元引导到中央空气净化器的空气量比常规设计的再处理设备中的少。
