• Operating from 1966 to 2015• Preparing for SAFSTOR• Creating a decommissioning
database for future generations based on Bentley technology
• Researching ways of presenting and organising information
• “An information system for decommissioning is absolutely required.”- Neolant

Conclusion
• Minimising risk through IT in nuclear decommissioning:− Today it’s about digitisation, decommissioning databases,
remote collaboration, work packaging, simulation, visualisation− Tomorrow it will be about open standard interoperability of
information and tools for lifecycle engineering management, and nuclear strength management of change
• Bentley is a leading IT provider in the nuclear engineering market
