Presentation Transcript

  1. Building Capabilities in Radiation Sciences School of Chemistry, Univ. of Manchester Simon M. Pimblott Dalton Cumbria Facility

  2. A £ 20+ million joint initiative between the University of Manchester and the Nuclear Decommissioning Authority

  3. Westlakes • 1. Research facility for non-active engineering decommissioning & radiation science studies • 2. University access to British Technology Center • 5% of allocation for UoM usage • 5% for academic collaborators under scheme administered UoM • “Nuclear Universities Research Consortium” BTC at Sellafield

  4. Nuclear Decommissioning & Waste Clean Up Research Challenges • PVC degradation by radiation • Radiation chemistry of mixed media, especially Pu containing systems • Production of molecular hydrogen (and the fate of complementary oxidant) • Understanding the effects of mixed radiation fields • Radiation induced production of corrosive agents • Effects of radiation on cements and grouts • Radiation effects on: • Interfacial process • Heterogeneous systems • Humid and damp systems • Hydrocarbons and organic polymers • Chlorinated materials • in realistic environments i.e. under pressure & at temperature. Research Needs

  5. Detailed model of radiation effects Track structure simulation ab initio theory Experiment & dataanalysis Effects of physico-chemical processes Radiation chemical& materials modeling Reaction dynamics theory

  6. Requirements • Physical infrastructure: • Mixed radiation types • Appropriate “analytic” support to allow surface and bulk interrogation • Computational facilities • Machine / electronics shop • Intellectual capacity: • Sustainable “resident” academic community

  7. Sources for Radiation Chemistry • Electron LINAC • Tandem Pelletron for1H, 4He & heavier ions • 60Co g irradiator
