摘要： Mobile apparatuses move within contaminated fluid to create fluid flows against structures that remove and prevent contaminant deposition on structure surfaces immersed in the fluid. Unsettling flows in water may exceed approximately 2 m/s for radionuclide particles and solutes found in nuclear power plants. Mobile apparatuses include pressurized liquid from a pump or pressurized source that can be chemically and thermally treated to maximize deposition removal. When spraying the pressurized liquid to create the deposition-removing flow, mobile apparatuses may be self-propelled within the fluid about an entire surface to be cleaned. Mobile apparatuses include filters keyed to remove the contaminants moved into the coolant by the flow, and by taking in ambient fluid, enable such filtering of the ambient fluid along with a larger flow volume and propulsion. Propulsion and the pressurized liquid in turn enhance intake of ambient fluid.

摘要： Safety valves accurately control closure and opening of fluid passage through the valve. Valves include a barrier that blocks the fluid until removal only by a high-energy projectile. Following removal and opening, the barrier or the projectile can flow through the valve, which remains open. Bullets, pneumatic pistons, shot, coilgun pellets and any other forceful projectile may impact and remove the barrier. The projectile is actuated with any type of chemical reaction, firing pin, spring release, accelerating circuit, ignition circuit. Catchers in the valve envelop or otherwise retain the projectile or barrier pieces and enter the fluid flow of the opened valve without blocking it. Disruptable barriers include strong but breakable glass plates, thin steel sheets, a rotatable door and other barriers that can withstand potentially over 10,000 psi of fluid pressure while closing the valve. Valves can use circuits to both monitor valve open/closed status and initiate firing the projectile.

摘要翻译： 移动设备在受污染的流体内移动以产生抵抗结构物的流体流动，其移除并防止在浸入流体中的结构表面上的污染物沉积。 在核电厂发现的放射性核素颗粒和溶质，水中不稳定的流量可能会超过约2 m / s。 移动设备包括来自泵或加压源的加压液体，其可以进行化学和热处理以最大程度地除去沉积物。 当喷射加压液体以产生沉积物去除流动时，移动装置可以围绕整个待清洁表面在流体内自行推进。 移动设备包括用于去除通过流动物移入冷却剂中的污染物的滤器，并且通过吸收环境流体，使得能够对较大流量和推进进行环境流体的这种过滤。 推进剂和加压液体又增加了环境流体的摄入。
