exposure (e.g. from criticality or loss of
shielding) requiring implementation of
urgent protective actions off-site.
This could be:
- actual or projected 72 severe core damage
or damage to large amounts (e.g. > 1/3 of
the core of a 3000 MW(th) reactor) of
recently discharged reactor fuel.
- actual damage to barriers or critical
safety systems that will result in a release
(e.g. of reprocessing waste) or criticality
protective action off-site
