This project is to replace the aging (and obsolete) detectors necessary for the operation of the AGN-201 research reactor at Idaho State University. The reactor is used by both faculty and students at ISU for the purposed of education, research and training. Currently, three antiquated BF3 filled radiation detectors serve the reactor safety channels. BF3 detectors are largely being discontinued due to the hazardous nature of the gas, which means it is no longer possible to buy replacements. Therefore, it is planned to replace the BF3 detectors with modern B-10 lined detectors.
