Conclusion
NS-INSP-GD-011 Capability Map: ONR Q1.4 SHOW effective audit and assurance arrangements for the emergency management programme
Sellafield Limited was able to describe and evidence how it conducts assurance on the emergency management programme across the three tiers that it has defined. Tier 1 audit and assurance activities are conducted by the Facility/Plant Dutyholders with support from Emergency Planners. The subsequent reports are summarised in status dashboards and are reported to the relevant Management Safety Committee each financial year. In addition, Tier 2 audit and assurance activities are conducted by the Head of Emergency Management Strategy and Policy across the Facility/Plant Dutyholders. Tier 3 audit and assurance activities are conducted by Nuclear Independent Oversight. In my opinion, Sellafield has evidenced effective audit and assurance arrangements for the emergency management programme.
NS-INSP-GD-011 Capability Map: Q6.11 CONDUCT effective and critical internal assessment of the emergency demonstration
Sellafield Limited provided evidence that the emergency demonstration exercise is systematically planned, prepared and reported by qualified and capable Emergency Planners (EP). The exercise summary reports from Emergency Planning and NIO were self-critical and evidence based. In my opinion, the reports represent honest assessments and identify areas for learning. Actions are identified which are tracked through the ATLAS system (electronic action database).
