The Nuclear Chemistry & Engineering Group supports Hanford Site cleanup, river corridor protection, nuclear materials stewardship, non-proliferation missions, the nuclear fuel life cycle, national security missions, and energy production, and is engaged in expanding the beneficial use of nuclear materials and radionuclides. Through high-quality fundamental and applied science and strong academic collaborations, we are fostering a renewed focus on radiochemistry and irradiated materials research for providing solutions in nuclear nonproliferation, environmental cleanup and protection, advanced nuclear energy, and for use in medicine and industry. Our team is seeking a recent college graduate to support our Radiation Detection capability. The selected candidate will assist with radiation spectroscopy counting operations in PNNL’s Radiochemical Processing Laboratory. The job will focus on use and improvement to portable gamma ray detection systems, developing algorithms and software for automated analysis of the advanced radio-emission spectroscopy systems, and studying the detection sensitivity to complex mixed fission/activation product samples. The candidate should have a working knowledge or be prepared to learn radiation transport, C / Python, and CERN’s ROOT & GEANT 4 data analysis & simulation frameworks; these skills will be leveraged to test developed analysis tools against complex bulk fission product spectra. The candidate will be expected to publish fundamental nuclear data and support open-source development of advanced radio-emission spectroscopy instrumentation & methods. The candidate may also assist with and learn radiochemistry methods, including sample digestions, chemical separations, and sample prep for gross alpha/beta counting, liquid scintillation counting, etc. Qualifications. Minimum Qualifications:Candidates must have received a Bachelor’s degree within the past 24 months or within the next 8 months from an accredited college or university. Preferred Qualifications:Bachelor’s degree in physics, nuclear engineering, computer science, or related field Experience with Geant 4 radiation transport code. Experience using HP - Ge detectors and analyzing their data. Experience with ROOT and/or C coding
