Exploring Radioactive Environments with Pipeline Devices

Research Area: Monitoring PI: Prof. Tom Scott Partners: Magnox Funders: Wood Plc (formerly AMEC Foster Wheeler) Contact details: Freddie.Russell-Pavier@bristol.ac.uk The Challenge Nuclear waste materials are transported, stored and processed in facilities that can are physically shielded from the outside environment. In these environments it is important to understand the distribution of radionuclides and how this […]

Long-term Bentonite Behaviour in Geological Disposal Facilities

Research Area: Waste and Fuel Management PI: Miss Macarena Leal Olloqui Contact details: Macarena.Lealolloqui@bristol.ac.uk The Challenge Despite producing considerable power density from a small volume of nuclear material, the main perceived drawback of nuclear-fission power generation are the long-term environmental impacts. A key environmental theme addressed by work at the University of Bristol includes long-term […]

Mapping Macro Areas with Nano Resolution Using High-Speed AFM

Research Area: Materials and Modelling PI: Dr Oliver Payton and Dr Loren Picco Contact details: Oliver.Payton@bristol.ac.uk Loren.Picco@bristol.ac.uk The Challenge The macro sized physical properties of a material are a product of the nano and micro sized structures within. The materials used in the Nuclear industry are no different. In order to better predict the lifespan […]

The Effect of Creep Strain Rate on Damage Accumulation in Type 316H Austenitic Stainless Steel

Research Area: Nuclear Materials and Modelling PI: Dr Mahmoud Mostafavi Funders: EDF Energy Contact details: M.Mostafavi@bristol.ac.uk The Challenge High temperature assessment codes such as R5 are mainly based on standard forward creep tests. Therefore the complex geometry and load multi-axiality of service components are often ignored when assessing their integrities via the standard codes. For […]
