Event description

Description

Hydrogen gas is generated in nuclear plants either during the course of normal operations (e.g. in waste storage as a consequence of radiolysis and corrosion) or under accident conditions (such as occurred at Three Mile Island and Fukushima).

The wide flammable range of hydrogen in air means that unless properly controlled, the generation and presence of hydrogen in a confined space will always present some likelihood that an explosion might occur, posing a serious risk to the safety of a structure and any people in its vicinity. The risk is particularly acute in plant situations in the nuclear industry where an explosion could threaten containment, leading to radioactive contamination of the surrounding environment, with potentially very serious consequences. It is therefore vitally important to be able to understand and safely manage such hydrogen hazards.

Nuclear Decommissioning and waste management arenas present unique challenges in relation to hydrogen hazards owing to the variety of activities including storage, transportation, and processing of waste. To maintain a safe and secure environment hydrogen evolution, diffusion, flow and venting must all be understood and managed.

This one day event will consider hydrogen safety hazards relevant to the nuclear industry during decommissioning and waste management processes, examining how they can be characterised, managed and mitigated. Topics covered during the event will include:

  • Hydrogen hazards management
  • Hydrogen generation
  • Ignition mechanisms
  • Hydrogen explosion modelling
  • Mitigation of hydrogen explosions

The event will be of interest to anyone who wishes to gain a greater awareness and understanding of hydrogen hazards and their management in nuclear decommissioning and waste management, including safety scientists, regulators, risk assessors, site licence companies and contractors.
