This project spans between fundamental nuclear structure physics research and precision measurement of industrially relevant radionuclides. The main objective is to develop a novel radiation detector system for gaseous nuclear fission residues via rapid, in-situ monitoring of the condition of nuclear fuel. The proposed system will utilise a high resolution, high sensitivity beta-gamma coincidence detector to measure the radioactive gases produced during nuclear fission (i.e. radiokrypton and radioxenon). By measuring the concentration and ratio of these gases, subtle changes in the condition of nuclear materials can be ascertained.
The primary deliverable of the PhD project, in collaboration with the National Physical Laboratory, is a prototype, digital coincidence radiation detector system to measure the activity concentration of fission product gases-in-air, thereby allowing real-time monitoring the state of stored nuclear fuel and materials. The proposed system comprises HPGe gamma-ray spectrometers, beta particle detectors, fast-timing digital read-out electronics, a bespoke radioactive gas sample cell and associated gas handling system. The detector system will work by measuring the gamma and beta radiation emitted from radioactive noble gases that have escaped the nuclear fuel or material. The radioactive gases are sampled from the air (or ventilation line) and pumped through a gas sample cell that sits between the pairs of gamma and beta detectors.
The project is also of interest to the UK and international security communities regarding the monitoring of fission material releases following nuclear weapons tests. The project will also involve collaborative work linked to fundamental nuclear structure research including determination and evaluation of primary nuclear decay data from very short-lived nuclear fission fragment with short half-lives performed at leading international nuclear physics laboratories in Japan (RIKEN) and Germany (GSI-FAIR- Phase 0).
The University of Surrey was established on 9 September 1966 with the grant of its Royal Charter, but its roots go back to a late 19th-century concern to provide greater access to further and higher education for the poorer inhabitants of London. Since the University's founding in the 1960s, and before that at Battersea College, our community has thrived through strong connections and collaboration with the outside world. We've formed close partnerships with other institutions and businesses, reaching across geographic boundaries, and used those relationships to bring potential to life.... continue reading
