    摘要: A guide ring is positioned in the reactor core vessel of a pebble-bed nuclear reactor to segregate fuel pebbles and reflector pebbles fed into the vessel through respective conduits. The reflector pebbles pass through the guide ring and form a reflector column, while the fuel pebbles pass outside the guide ring and form an annular fuel column surrounding the reflector column. The guide ring controls the size and shape of the reflector column and controls mixing of the two types of pebbles. Furthermore, the fuel pebbles can have a substantially larger diameter than the reflector pebbles. Accordingly, the fuel-pebble column will have more void space, and cooling gas will consequently flow preferentially through the fuel-pebble column.

    摘要: This invention provides devices and apparatuses comprising the same, for efficient pumping and/or mixing of relatively small volumes of fluid. Such devices utilize nonlinear electrokinetics as a primary mechanism for driving fluid flow. Methods of cellular analysis and high-throughput, multi-step product formation using devices of this invention are described.
