ONR inspectors observed Dounreay’s annual Level 1 Site Safety Demonstration Exercise, Delta 60. ONR assessment focused on Dounreay’s arrangements for command & control, casualty management & recovery, and emergency dose management.

Observations were provided to site on some areas where improvements could be made, including: aspects of the management of contaminated personnel, good practises for ensuring site communications, appropriate consideration of communications whilst wearing medical protective equipment and ensuring that “notional” exercise play is kept to a minimum on key aspects of the demonstration.
