- Assumptions used for the energy dissipated in the divertor during a disruption are similar to assumptions used in the ITER safety analysis
- Following a disruption, off-site doses could be produced by direct vaporization of the divertor surface layer
- Total Energy dissipated during the energy quench phase is 2.1 GJ
- During a disruption, very small particles (0.1 mm) are mobilized by direct vaporization
- Assuming an interaction surface area of 15 m2, the total amount of tungsten vaporized during a disruption is 1.16 kg
