SMiRT 23 Themes
The overall theme for SMiRT 23 is “Using existing challenges to champion the Next Generation”. As part of this, we will be promoting an Early Career Award for individuals within 10 years of starting their professional career.
As part of the scope of the standard SMiRT divisions, focussed topics for SMiRT 23 include:
- Nuclear Applications of Graphite
- High Temperature Assessment
- New build and the harmonisation of codes and standards
- Small modular reactors (SMRs)
- Flooding Hazards – developments post Fukishima
- Component Fragility of Nuclear Power Plants
