摘要： The flow of air through a fume hood is optimized by producing a bi-stable vortex within the vortex chamber of the fume hood regardless of sash movement. A bi-stable fume hood optimizes capture face velocity to minimize backflow of fume laden air through the hood sash opening. This bi-stable vortex fume hood reduces the energy consumption up to sixty percent versus the present day mono-stable vortex fume hoods. The bi-stable vortex fume hood utilizes a vortex pressure control system to reposition top, center, and bottom slot openings of a baffle in the hood. This baffle moves the bi-stable vortex away from the fact when the sash is fully opened and creates a clearing action near the work surface as the sash is closed. The fume hood's airfoil is placed inside the fume hood chamber and the airfoil has multiple entry pattern, one of which turns the vortex up and away from the open sash window. The other creates flow which washes the work surface of the hood. The interior portion of the vortex chamber utilizes a turning vane in order to decrease dynamic losses and increase bi-stable vortex stability.
摘要翻译： 通过通风柜的空气流动通过在通风橱的涡流室内产生双稳态涡流而优化，而不管窗扇运动如何。 双稳态通风橱优化捕获面速度，以最大限度地减少吸烟烟气回流通过罩带窗口。 这种双稳态涡流通风机与目前的单稳态涡街通风机相比，能耗降低了百分之六十。 双稳态涡流罩采用涡流压力控制系统来重新定位罩中挡板的顶部，中心和底部槽口。 当挡板完全打开时，这个挡板将双稳态涡流移动离开事实，当窗扇关闭时，会在工作表面附近产生清除动作。 通风柜的翼型放置在通风橱室内，翼型具有多个入口模式，其中一个将涡流向上旋转并远离开放的窗框。 另一个产生洗涤罩的工作表面的流动。 涡流室的内部使用转动叶片，以减少动态损耗并增加双稳态涡流稳定性。

摘要： A double tube modular coil steam generator is provided in which a multiplicity of inner tubes conducting water are individually surrounded by outer tubes containing liquid metal as a heat transfer agent. The double tubes form into coils, providing a large surface area while conserving space. Immersion of the double tube coil in hot liquid metal, e.g., from the core of a nuclear reactor, causes efficient transfer of heat across the liquid metal in the outer tube to the water in the inner tube, creating superheated steam, which can be cycled to a turbine and converted to electrical power.The efficiency, reliability and safety of the multiple double tube design of the steam generator obviates the necessity of many secondary heat removal and emergency components in addition to conserving space and material. The modular design allows ease of operation, fabrication and repair.

摘要： A liquid metal circulation system is disclosed which is suitable for use in connection with a nuclear reactor. The circulation system of the invention includes an electromagnetic pump having a central core body featuring a helically configured, six pole magnet, optionally directing flow to one or a series of flow couplers, which generates sufficient liquid metal flow to be used as the primary circulation means for the nuclear reactor. The increased safety, design simplicity, and efficiency of such circulation system overcomes many of the drawbacks of conventional circulation systems.

摘要： A nuclear reactor is provided characterized by a circulating liquid metal cooling system comprising a heat exchanger having a closed intermediate heat transfer fluid circuit in the form of a helical coil juxtaposed with the liquid metal coolant system, which effectively transfers heat through the intermediate circuit to a secondary fluid circuit. The intermediate heat transfer fluid circuit, which completely separates the liquid metal cooling system from the secondary fluid circuit, prevents potentially dangerous reactions between the primary liquid metal coolant and the secondary fluid (e.g., water).The efficiency, reliability and safety of the heat exchanger features eliminates the need for many secondary heat removal and emergency components in the design of the nuclear reactor.
