Abstract: A system for removing particulates of a fissile material includes first and second filtration paths. A first filter and a first valve are disposed in the first filtration path. A second filter and a second valve are disposed in the second filtration path. The first valve and the second valve are configured to switch between a dual open state and a mixed open/closed state. During the dual open state, the first valve and the second valve axe open to permit concurrent flows of the effluent gas through the first and second filtration paths. During the mixed open/closed state, one of the first valve and the second valve is open while the other of the first valve and the second valve is closed to permit the particulates on a corresponding one of the first filter and the second filter to be dislodged by a countercurrent flow of a purging gas.

Abstract: A method of operating a vaporization system including a first cylinder, a second cylinder, and an eductor having a suction inlet, a motive inlet, and an outlet is provided. The method includes vaporizing uranium hexaflouride in the first cylinder, channeling the vaporized uranium hexaflouride in the first cylinder to the suction inlet of the eductor, monitoring the pressure of the vaporized uranium hexaflouride channeled to the suction inlet, and channeling the vaporized uranium hexaflouride through the outlet. The method also includes vaporizing uranium hexaflouride in the second cylinder, and channeling the vaporized uranium hexaflouride in the second cylinder to the motive inlet of the eductor when the flow of uranium hexaflouride channeled to the suction inlet is below a predetermined amount.
