Cutting and removing activated and contaminated structures.
Segmentation of the reactor pressure vessel and internals is the dose-driving activity in most projects, which is why remote and underwater cutting are used.
Waste characterisation runs alongside dismantling: what cannot be measured directly is estimated using scaling factors from key nuclides.
