• Act as the “intelligent customer” for C&I deliverables from the Technology Partner, providing informed challenge, clarification and acceptance recommendations.
• Support responses to regulator questions and technical queries relating to C&I.
• Ensure C&I analysis and documentation comply with relevant UK and international standards, codes, ONR expectations and internal nuclear safety principles.
• Contribute to ALARP demonstrations and identification of reasonably practicable improvements.
• Monitor progress, quality, risk and change across tasks, ensuring delivery to agreed time, cost and quality constraints.
• Provide regular C&I status updates, risk/issue summaries and decision inputs to the Reactor Island Lead and wider project management team.
• Contribute to building a positive safety culture and a high performing technical community aligned with client values.
