Abstract: An apparatus is provided for storing hazardous waste material, which includes one or more of spent nuclear fuel, radioactive material, and fissionable material. A fusible alloy material, for example, a eutectic material, resides within the apparatus and surrounds the hazardous waste material. In the preferred embodiments, it is suggested that the fusible alloy material exhibits liquidus and solidus or melting temperatures that are between about 100 and 300 degrees Fahrenheit for facilities using the apparatus and methods for liquid storage pool loading applications.

Abstract: The present invention relates to improving the ability of a hyphenated instrument to analyze a sample benefiting from having the first instrument's analysis of the same sample. A fast switching mechanism can be used as the interface between an ion mobility spectrometer (IMS) and a mass spectrometer (MS) such that the obtained IMS spectrum is converted into a timing diagram that controls the vacuum inlet's size dynamically during analysis of a neutral and/or charged chemical and/or biological species such that a smaller pumping system can be used. In various operational modes of the IMS-MS device, mobility-separated ions are allowed to pass through an ion gate and the vacuum inlet for mass analysis.

Abstract: An ultraviolet air sanitizer apparatus for HVAC systems has a frame defining a flow passage therethrough configured such that the frame rear is insertable into a return air inlet of the HVAC system. A sanitizer light is disposed within the flow passage. When activated, the sanitizer light emits germicidal ultraviolet light into the surrounding flow passage. A light baffle is disposed within the flow passage upstream of the sanitizer light and allows air flow but blocks light. An air pressure sensing switch is electrically connected to the sanitizing light and configured to measure air pressure differential across an air filter. When the air pressure differential is a predetermined value or greater, which is indicative of air circulation by the HVAC system, the switch turns on the sanitizer light. When the pressure differential is less than the predetermined value, the switch turns off the sanitizer light.

Abstract: One or more air baffles are provided for an apparatus that sterilizes air in a room using UVC radiation. At least one baffle within an air sterilization enclosure is arranged so the baffle is proximal to the at least one UVC light source. The baffle is designed and positioned to create air turbulence within the enclosure to increase the dwell time of a given volume of the air in the enclosure, and to reduce the effective distance of a given volume of air to the UVC light sources. Thus, airflow is hindered by the baffle in its passage through the enclosure in order to increase the UVC exposure to that volume of air.
