Storage of Nuclear Fuel: Radiolytic Dissolution at the UO2/H2O Interface

Research Area: Waste and Fuel Management PI: Dr Sophie Rennie Contact details: Sophie.Rennie@bristol.ac.uk The Challenge A key problem facing the nuclear industry is the safe and efficient long-term storage of nuclear fuel. The long-lived radiation fields that result from highly radioactive fission products require spent nuclear fuel to be stored over timescales of tens of […]

PLATINUM – Pulsed Laser Accelerators for the Inspection of Nuclear Materials

Research Area: Waste and Fuel Management PI: Dr Chris Jones Contact details: cj0810@bristol.ac.uk The Challenge As of 2013 the UK currently stores 120,000 tonnes of Intermediate Level Waste (ILW) nationwide, with a further 190,000 tonnes predicted from decommissioning existing sites. This waste is reprocessed prior to storage in 500 litre stainless steel drums backfilled with […]

Evaluation of Waste Package Degradation Resulting from Metallic Corrosion

Research Area: Waste and Fuel Management PI: Mr Haris Paraskevoulakos Partners: Diamond Light Source Contact details: cp13846@bristol.ac.uk The Challenge Within the UK, nuclear waste is classified according to the levels of radioactivity in three groups: High Level Waste (HLW), Intermediate Level Waste (ILW) and Low Level Waste (LLW). ILW mostly consists of metallic fragments arisen […]

Diamond Detectors for Dose Rate Measurements in Highly Active Environments

Research Area: Waste and Fuel Management PI: Dr Chris Hutson Partners: Sellafield Contact details: Chris.Hutson@bristol.ac.uk The Challenge Decommissioning legacy nuclear facilities requires innovative characterisation technologies due to extreme levels of radioactive hazard, which destroys or saturates conventional detectors. Such technologies will be required to map multiple sources of radioactivity in facilities which have small access […]

Use of an Ice Pig to Help Reduce and Remove Active Contamination

Research Area: Waste and Fuel Management PI: Prof. Joe Quarini Partners: Agbar Environment Contact details: Joe.Quarini@bristol.ac.uk The Challenge One of the important aspects of nuclear decommissioning is minimising the resultant contaminated volumes. The use of water, acids, organic solvents in cleaning contaminated equipment results in difficult/embarrassing to handle volumes of active effluent streams. The problem […]

Inductively-Coupled Ultrasonic Sensors for Monitoring ILW Drum Integrity

Research Area: Monitoring PI: Prof. Paul Wilcox Partners: Inductosense Contact details: P.Wilcox@bristol.ac.uk The Challenge In the UK alone, over 20,000 Intermediate Level Waste (ILW) drums are currently stored in above ground facilities. Confirming the integrity of the drums while in storage over extended time periods is challenging due to the restricted access, and the desire […]
