摘要： A boiling water reactor control rod drive support system having radiation shields to protect persons working under the reactor vessel from radiation exposure and to limit the travel of a control rod in the event that a control rod housing is ruptured. The radiation shields include radiation shield rings for surrounding the control rod drive housing and radiation shield cups for surrounding the bottom portion of the control rod drive. The radiation shield rings can be used with support systems having radiation shield cups placed on rows of support bars or with existing support systems.

摘要： A method of removing in-core instruments and dry tubes from a boiling water reactor during a refueling outage wherein a pair of temporary storage containers are provided in the reactor core. A remotely operated cutting device is superposed on the first temporary storage container. An instrument is suspended by an end, with the in-core part uppermost, and lowered until a portion of the out-of-core part is within the first temporary storage container. The cutting device is then operated to sever the instrument portion within the temporary storage container. The instrument is repeatedly lowered, and portions severed, until all of the out-of-core part of the instrument is in the first temporary container. The in-core part of the instrument is then lowered into the second temporary container and the two temporary containers are removed from the reactor cavity using the existing equipment-handling crane.

摘要： In order to eliminate the need to weld, drill or otherwise machine a shroud structure which is used to surround a plurality of fuel assemblies in a nuclear reactor, a plurality of upper hanger rods interconnect a structure above the shroud to a support ring which is clamped about the upper periphery of the shroud. Lower hanger rods interconnect a lower edge or shoulder portion of the shroud with the support ring. Thus, through the upper and lower hanger rods and the support ring, the shroud can be supported within the RPV. The upper support ring is arranged to clamp the lower ends of the upper hanger rods against the upper outer peripheral portion of the shroud while the lower ends of the lower hanger rods are clamped against the lower peripheral wall portion of the shroud by a lower support ring.

摘要： In order to provide a relatively inexpensive water-tight telescopic enclosure which can extend automatically upon demand, a tubular extension piece is reciprocally mounted on a container-like hook box structure. A tube seal which interconnects the hook box and the tubular extension provides a watertight connection between the two members and also provides an air space in a folded portion in which air can collect and produce buoyancy as the hook box is lowered into water. The tubular extension also has a larger cross-sectional area than the hook box and thus produces additional buoyancy. When the hook box is lowered into water the extension piece automatically floats upwardly to prevent the intrusion of water into the interior of the hook box and thus prevent contamination of pieces of apparatus enclosed therein.
摘要翻译：为了提供可以根据需要自动延伸的相对便宜的防水伸缩壳体，管状延伸件可往复地安装在容器状钩盒结构上。连接钩盒和管状延伸部的管密封件在两个构件之间提供了水密连接，并且还在折叠部分中提供空气空间，在折叠部分中空气可以收集并且当钩盒被放入水中时产生浮力。管状延伸部还具有比钩盒更大的横截面面积，从而产生额外的浮力。当挂钩盒被放入水中时，延伸件自动向上浮动，以防止水侵入钩盒内部，从而防止其中封闭的装置的污染。

摘要： An auxiliary platform has a one-ton hoist which may be used in conjunction with a rigid pole handling system. The positioning of the one-ton hoist, as well as the positioning of a trolley on which the hoist is mounted and the positioning of the platform, is centrally controlled at a control panel. In one embodiment, a new set of tracks are provided on either side of a refueling pool. A pair of cavity platforms are installed over the edges of the reactor cavity to receive the new set of tracks and to thereby allow the auxiliary platform to travel over the reactor cavity. In another embodiment, the existing tracks are extended and a single new track is provided between the equipment pool and the reactor pressure vessel head pedestal and spent fuel cask washdown area. The auxiliary platform is made extendable so that it can travel over the width of the existing tracks and also over width defined by the new track and one of the existing tracks. The auxiliary platform can work independently of the refueling platform on a separate task or can aid the refueling platform in performing a single task. The auxiliary platform can both shorten the critical path time and reduce the exposure of radiation to workers.
摘要翻译：辅助平台具有一吨提升机，可与刚性杆处理系统结合使用。一吨起重机的定位以及安装起重机的手推车的定位和平台的定位在控制面板上集中控制。在一个实施例中，在加油池的任一侧提供一组新的轨道。一对空腔平台安装在反应堆空腔的边缘上以接收新的一组轨道，从而允许辅助平台在反应器腔体上行进。在另一个实施例中，现有的轨道被延伸，并且在设备池和反应堆压力容器头座和废燃料桶冲洗区域之间提供单个新的轨道。辅助平台是可扩展的，使得其可以在现有轨道的宽度上移动，并且还可以在由新轨道和现有轨道之一定义的宽度之间行进。辅助平台可以独立于加油平台独立工作，或者可以帮助加油平台执行单个任务。辅助平台可以缩短关键路径时间，减少辐射对工人的辐射。
