    摘要： A nuclear reactor having a remotely removable and replaceable thermal insulating shield for the head. Access permitting removal and replacement of the head is thus afforded.The thermal insulating shield includes a vertical frame of insulating material of polygonal transverse cross section encircling the head. A top panel of insulating material is mounted on the top of the frame pivotal by remote actuation between a horizontal position and a retracted position which may be vertical. In the horizontal position, the panels mate to provide thermal shielding for the head.

    摘要： A modular reactor head shielding system formed from a plurality of flexible pads shaped to interleave with the edges of each adjacent pad around the reactor head. The shielding system is assembled to protect workers from radiation exposure in working in the area around the reactor head or when working on the reactor head during refueling of the reactor. The pads are formed by inserting a pair of blankets secured to one another inside a pair of outer covers which are secured to one another in offset relation to form an interleave or tongue and groove configuration to eliminate radiation paths between pads. The blankets are formed by quilting lead wool within the blanket covers. Each pad has a hanging plate secured to one end which can be hung from a frame around a reactor head or from the reactor head itself. The pads are secured to one another such as with straps to insure elimination of radiation paths therebetween.

    摘要翻译： 由多个柔性垫形成的模块式反应器头部屏蔽系统，其形状与每个相邻焊盘的​​围绕反应器头部的边缘交错。 屏蔽系统被组装以保护工人免受在反应堆头周围区域工作的辐射暴露或在反应堆加油期间在反应堆头上工作时。 衬垫通过将一对彼此固定的毯子插入一对外盖内而形成，所述一对外罩以偏移关系彼此固定，以形成交错或舌形和沟槽结构，以消除衬垫之间的辐射路径。 毛毯通过在毯子盖内绗缝铅羊毛来形成。 每个垫具有固定到一端的悬挂板，其可以从反应器头部周围的框架或从反应器头本身悬挂。 垫片彼此固定，例如用带子，以确保消除它们之间的辐射路径。

    摘要： The method comprises applying on the surface of each of the parts a thin layer of a curable first mixture containing a first resin which cures slowly and is slightly exothermic and has a good adherence to said surfaces. A curable second mixture is then introduced in a space defined by the layers of the first mixture in the final position of the two parts. The second mixture contains a second resin which cures rapidly and is sufficiently exothermic to promote the curing of the first resin and normally has after curing a poor adherence to said surfaces but a good adherence to the first resin.

    摘要： A shield for use with nuclear reactor systems to attenuate radiation resulting from reactor operation. The shield comprises a container preferably of a thin, flexible or elastic material, which may be in the form of a bag, a mattress, a toroidal segment or toroid or the like filled with radiation attenuating liquid. Means are provided in the container for filling and draining the container in place. Due to its flexibility, the shield readily conforms to irregularities in surfaces with which it may be in contact in a shielding position.
