Nuclear & radiological preparedness
Preparedness is built before the emergency.
Nuclear and radiological preparedness is the flagship field of IARS. It brings together technical rigour, institutional coordination, operational capacity, decision-making, communication and human factors in a system that has to work coherently when time is short and information may be incomplete.
A facility may have robust safety systems, and an institution may have detailed plans and procedures. Preparedness becomes real only when roles are understood, information travels, institutions cooperate, decision-makers can act, and the public receives clear and credible instructions.
IARS analyses and supports the whole chain of preparedness: from understanding the risk and planning, through exercises, response evaluation and public communication, to the integration of lessons learned.
Preparedness and response
We contribute to developing and evaluating preparedness and response arrangements for nuclear and radiological emergencies. We examine responsibilities, coordination mechanisms, activation levels, information flows and the relationship between technical assessment and decisions on protective measures.
- Assessing capabilities and the level of preparedness.
- Roles, responsibilities and coordination mechanisms.
- Notification, information and decision flows.
- Continuity of essential functions.
- Organisational and technical interoperability.
- Integration of lessons learned.
Exercises and simulations
Exercises make it possible to test plans under controlled but realistic conditions. They can reveal vulnerabilities that document review alone does not show: delays, unclear responsibilities, information that cannot be used, different readings of the same situation, or a lack of coordination between the operational response and public communication.
IARS can contribute to defining objectives, developing scenarios, facilitating exercises, observing performance and formulating improvement measures.
Decision-making under uncertainty
In an emergency, decision-makers have to act before the picture is complete. We support the development of mechanisms that turn technical, operational and public information into clear decision options.
We also examine the effects of time pressure, cognitive load, contradictory information and distributed responsibility on individual and institutional performance.
Communication and trust
A nuclear or radiological emergency produces an operational situation and an informational one at the same time. The distance between what is happening and what people understand can itself become a vulnerability.
Communication is therefore not treated as a secondary activity but as part of the response. Messages have to explain the situation, the uncertainties, the protective measures and the actions expected of the public.
Emerging risks and the resilience of nuclear infrastructure
Preparedness has to take account of the changing context in which nuclear infrastructure operates. IARS follows topics such as:
- Preparedness for small modular reactors.
- Climate change and slow-onset external hazards.
- Extreme events and cumulative effects.
- The interface between safety, security and cybersecurity.
- Hybrid threats.
- Information integrity and disinformation.
- Operational continuity in complex situations.
- Regional cooperation and cross-border events.
The IARS approach connects components that are often analysed separately.
The aim is that technical expertise can be turned, in time, into decisions, protective actions and information that people can understand and use.
Collaborate with us
We work with institutions, organisations, experts and professional communities on projects that turn analysis into preparedness and action. If you face a challenge that calls for complementary perspectives, an independent assessment or a framework for dialogue, we would like to talk.
