摘要： A nuclear power plant has a cooling system that operates under a variety of temperature and pressure conditions. A storage container is provided to allow expansion of fluid within the cooling system, and access is gained to the interior chamber of the container via a rupture disc. When pressure above a design threshold is exceeded, the rupture disc ruptures allowing fluid to fill the chamber. When desired, a valve may be opened to allow fluid to exit the chamber and travel to a desired location.

摘要： A nuclear fission reactor combined with a propellant actuated depressurization and/or water injection valve is disclosed. The depressurization valve releases pressure from a water cooled, steam producing nuclear reactor when required to insure the safety of the reactor. Depressurization of the reactor pressure vessel enables gravity feeding of supplementary coolant water through the water injection valve to the reactor pressure vessel to prevent damage to the fuel core.

摘要： A shock absorber system was designed to absorb the energy imparted to doors in a nuclear reactor ice condenser compartment as they swing rapidly to an open position. Each shock absorber which is installed on a wall adjacent each door is large and must absorb up to about 40,000 foot pounds of energy. The basic shock absorber component comprises foam enclosed in a synthetic fabric bag having a volume about twice the foam volume. A stainless steel knitted mesh bag of the same volume as the fabric bag, contains the fabric bag and its enclosed foam. To protect the foam and bags during construction activities at the reactor site and from the shearing action of the doors, a protective sheet metal cover is installed over the shock absorber ends and the surface to be contacted by the moving door. With the above shock absorber mounted on a wall behind each door, as the door is forcibly opened by steam pressure and air resulting from a pipe break in the reactor compartment, it swings at a high velocity into contact with the shock absorber, crushes the foam and forces it into the fabric bag excess material thus containing the foam fragmented particles, and minimizes build-up of pressure in the bag as a result of the applied compressive force.
摘要翻译：设计了一种减震器系统，用于吸收在核反应堆冰冷凝器舱内迅速摆动至打开位置时施加给门的能量。安装在每个门附近的墙壁上的每个减震器是大的，并且必须吸收高达约4万英尺磅的能量。基本的减震器部件包括封闭在具有约两倍泡沫体积的体积的合成织物袋中的泡沫。与织物袋相同体积的不锈钢针织网袋包含织物袋及其封闭的泡沫。为了在反应堆场所的施工活动期间和门的剪切作用下保护泡沫和袋子，在缓冲器端部和被移动的门接触的表面上安装有保护金属板盖。将上述减震器安装在每扇门后面的一个墙壁上，当门被反应室内管道破裂所产生的蒸汽压力和空气强行打开时，它以高速摆动与缓冲器接触，将泡沫压碎并将其压入织物袋过剩的材料中，从而包含泡沫碎片颗粒，并且由于施加的压缩力，使袋中的压力积聚最小化。

摘要： The disclosure describes hydrocarbon flowline corrosion inhibitor overpressure protection. Such a protection system includes a fluid flow pathway fluidically coupled to a corrosion inhibitor injection pump that injections corrosion inhibitor into a hydrocarbon carrying flowline. When the injection pump pressure exceeds a threshold flow pressure, the corrosion inhibitor is flowed through a first branch of the fluid flow pathway to relieve the excess pressure. The first branch is fluidically isolated from a second branch. When a rupture disc in the first branch fails, then the corrosion inhibitor is diverted to flow through the second branch and the first branch is isolated from the corrosion inhibitor flow.

摘要： A pyrotechnic-actuated valve assembly may include an insert body having an inlet, an outlet, and a flow path extending from the inlet to the outlet. The insert body is formed of a first alloy. A shear structure is bonded to the outlet of the insert body so as to close the flow path. The shear structure is formed of a second alloy. The second alloy of the shear structure is bonded to the first alloy of the insert body so as to form a hermetic seal. The dual-alloy nature of the valve assembly allows a relatively clean shearing of the shear structure during actuation, thus reducing or preventing the occurrence of deformation and/or material fragments in the flow path.

摘要： Simplified nuclear reactors include depressurization systems or gravity-driven injection systems or both. The systems depressurize and cool the reactor without operator intervention and power. An underground containment building may be used with the depressurization and injection systems passing through the same from above ground. Depressurization systems may use a rupture disk, relief line, pool, and filter to open the reactor and carry coolant away for condensation and exhausting. Injection systems may use a coolant tank above the nuclear reactor to inject liquid coolant by gravity into the reactor through an injection line and valve. The rupture disk and valve may be integral with the reactor and use penetration seals where systems pass through containment. Rupture disks and valves can actuate passively, at a pressure setpoint or other condition, through fluidic controls, setpoint failure, etc. The depressurization system and injection system together feed-and-bleed coolant through the reactor.
