Key findings, inspector's opinions and reasons for judgement made
ONR observed the annual Level 1 Site Safety Demonstration Exercise, Delta 58, focusing on command and control at the scene, casualty management and recovery, and emergency dose management. Overall ONR considers that this was an adequate demonstration of DSRL's emergency arrangements against the requirements of LC11 and the relevant good practice provided within ONR's guidance document NS-INSP-GD-011. DSRL also used this exercise as an opportunity to undertake detailed planning of the recovery from this incident. This is an area that is not formally exercised as part of a Level 1 Safety Demonstration exercise and ONR welcomed the opportunity to observe the site's considerations in this aspect of the site's emergency response and recovery arrangements.
Conclusion
Based on the observations of the ONR assessment team, we consider that this was an adequate demonstration of DSRL's emergency arrangements against the requirements of LC11 and the relevant good practice provided within ONR's guidance document NS-INSP-GD-011. On this basis, ONR has awarded an inspection rating of GREEN.
