Analysing and imaging of fuel debris fallout particles from Fukushima Daiichi Power Plant accident

Research Area: Nuclear Hazards and Risks PI: Dr Peter Martin Partners: Diamond Light Source, Japan Atomic Energy Agency Contact: peter.martin@bristol.ac.uk The Challenge Although the three nuclear reactors at the Fukushima Daiichi Nuclear Power Plant (FDNPP) were not damaged by the magnitude 9.0 earthquake in 2011, the entire site was inundated by the ensuing 15m high […]

Radiation mapping surveys using UAVs in the Chernobyl Exclusion Zone

Research Area: Nuclear Hazards and Risks PI: Prof. Tom Scott Partners: National Centre for Nuclear Robotics, EPSRC Contact details: t.b.scott@bristol.ac.uk The Challenge The accident at the Chernobyl nuclear power plant occurred during the early hours of Friday 26th April 1986 during a test on the Chernobyl 4 reactor prior to a routine shutdown. The resultant […]

Insights into Digital Twins

The Design and Manufacturing Futures laboratory, based at the University of Bristol, is researching and creating the tools and technologies of tomorrow, providing game-changing capability for the design, manufacture, operation and disposal of next generation products and machines. While very often based on a virtual prototype (inc. multi-physics) a digital twin has: a role beyond […]

Probabilistic treatment of stresses for use in creep-fatigue crack initiation assessments

Research Area: Structural Integrity PI: Mr Nader Zentuti Funders: EDF Energy Contact details: nader.zentuti@bristol.ac.uk The Challenge For assessing a component operating at high temperatures for creep-fatigue damage which can lead to crack initiation, the stress state during nominal operating conditions is required. These stresses are usually obtained from complex thermal and mechanical FE. However, using […]

High-Resolution Radiation Mapping to Characterise Contamination

Research Area: Waste and Fuel Management PI: Dr Peter Martin and Mr Dean Connor Partners: Sellafield Ltd. Contact details: Peter.Martin@bristol.ac.uk and Dean.Connor@bristol.ac.uk The Challenge Radiological contamination exists at numerous sites worldwide; whether the result of large-scale radiological release events (such as the Fukushima Daiichi Nuclear Power Plant accident in March 2011), following nuclear weapons testing, […]

Creep Deformation and Damage During Stress Relaxation in Stainless Steel Weldments Operated at High Temperature

Research Area: Structural Engineering PI: Mr Satyajit Dey Funders: EDF, Atkins Contact details: sd15325@bristol.ac.uk The Challenge Many engineering steel components used in power generation plants are operated at creep regime temperatures. This means that the steels are susceptible to creep and stress relaxation. It is important to estimate the amount of creep strain accumulation during […]
