Building Capabilities in Radiation Sciences
Simon M. Pimblott
Dalton Cumbria Facility
School of Chemistry, Univ. of Manchester
A £ 20+ million joint initiative between the University of Manchester
and the Nuclear Decommissioning Authority
Westlakes
BTC at Sellafield
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”
• 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
Research Challenges
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.
