Chemical Aspects of Nuclear Technology

PHYS65290 Chemical Aspects of Nuclear Technology 15 Full year Postgraduate Taught Level 6 Francis Livens Unit coordinator Scott Heath Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Masters/Integrated Masters P4 ' European Credit Transfer & Accumulation System Rating : 7.5 The module will be delivered over 5 successive days. Given the diversity of the student group, we cannot assume significant chemical background, hence the inclusion of an introduction/refresher day (Day 1) Running order may change depending on staff availability. Day 1 Introduction to Key Chemical and Physical Principles (Scott Heath). Oxidation states, ions in solution, hydrolysis and complexation. Kinetic and thermodynamic control, solubility and precipitation. Equilibrium constants. Salient features of radioactivity and detection. Day 2 ½ day on Source Terms- the Example of the Fusion Fuel Cycle (Francis Livens) Tritium production and processing; lithium source materials; ½ day on Radiation Chemistry (Fred Currell, Alex Baidak, External TBC*). Free radical chemistry, linear energy transfer, radiation tracks. Radiolysis of water. Case study: PVC behaviour in Pu cans. Day 3. Environmental Radiochemistry (Francis Livens, Liam Abrahamsen-Mills*). Sources of natural and artificial radioactivity. Chemistry of natural and engineered environments- clays, hydrous oxides, natural organic matter. Ion exchange and surface complexation processes. Colloids and nanoparticles. X-ray absorption and electron microscopic characterisation. Case study: Legacy Ponds & Silos Day 4. PWR Coolant Chemistry (Fabio Scenini, Nick Jones*). Chemistry control during normal operations. Effects of chemistry on generation and transport of radioactivity. Influence of operating chemistry on materials selection, degradation and performance. Startup and shutdown chemistry. Day 5 Analytical and Forensic Radiochemistry (Francis Livens, Scott Heath, Olivia Marsden*) Gross counting techniques, radiochemical separation, alpha and beta counting, environmental gamma spectrometry, atom counting techniques. Nuclear forensics- intrinsic and extrinsic properties, elemental and isotopic fingerprinting. Case studies: Heisenberg Cube; Operation Whimbrel The module will be delivered over 5 successive days.
