Abstract:
A scintillator-camera system for determining uniformity of radiation emission from a radioactive source includes a cylindrical scintillation detector (22), the scintillation detector (22) having a central hole along the long axis and having a conical mirror (27) around the scintillator (22) to direct light emitted from the circumference of the scintillator (22) to a camera (21). The camera (21) is arranged to view the scintillation detector (22) so that light stimulated in the scintillator (22) by a radioactive source inserted in the central hole is detected by the camera (21), the camera (21) producing image data upon detection of light stimulated in the scintillator (22). The image data are adapted to be analyzed to detect non-uniformity in a radiation emission pattern from the radioactive source. The image from the thick scintillator (22) and surrounding conical mirror (27) provides information about both circumferential, i.e., radial, and axial emission non-uniformities in a single view of the radioactive source(s) or seed(s) within the thick scintillator (22).
Abstract:
Disclosed are a radioisotope activity surveillance system and methods. The system includes a fuel rod assembly having a plurality of nuclear fuel rods and a target assembly having a top nozzle including an orifice plate and at least one target material rod fixedly coupled to the orifice plate. The least one target material rod is slidably disposed within the fuel rod assembly. A sensing assembly defines an opening sized and configured to receive the target assembly therethrough. The sensing assembly includes a self-powered detector assembly to detect radioisotope activity of the target rod material. Also disclosed is a method for measuring a self-powered detector signal to calculate radioisotope activity of a target assembly and a method for analyzing total activity of a desired radioisotope.
Abstract:
Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, while cooling equipment and the biomass to prevent overheating and possible distortion and/or degradation. The biomass is conveyed by a conveyor, which conveys the biomass under an electron beam from an electron beam accelerator. The conveyor can be cooled with cooling fluid. The conveyor can also vibrate to facilitate exposure to the electron beam. The conveyor can be configured as a trough that can be optionally cooled.

Abstract:
Method and system for irradiating articles using a first and second radiation sources respectively disposed at first and second gaps in the process conveyor in the target region respectively irradiate the articles in both tracks in opposite directions from positions above and below the articles. Articles on the tracks may be (a) diverged on the first load conveyor to separate the articles from the dividers, (b) converged on the process conveyor to minimize the width of the radiation sources and (c) diverged on the second load conveyor. If one of the radiation sources is not operative, the other source may irradiate the opposite sides of the articles during article movements sequentially on the first tracks of the first load conveyor, the process conveyor and the second load conveyor and then sequentially on the second tracks of the first load conveyor, the process conveyor and the second load conveyor. The articles are inverted during their transfer from the first track of the second load conveyor to the second track of the first load conveyor.
