Working Party on Nuclear Emergency Matters (WPNEM)

The NEA has a long tradition of expertise in the area of nuclear emergency policy, planning, preparedness and management. Through its technical programmes, the NEA offers its member countries unbiased assistance in the nuclear preparedness arena, with a view towards facilitating improvements in nuclear emergency preparedness strategies and nuclear emergency response at the international level, with a particular focus on decision-making, international communication, information exchange and the compatibility of response actions between various countries.

The mission of the CRPPH Working Party on Nuclear Emergency Matters (WPNEM) is to improve nuclear emergency management systems within member states, and to share its knowledge and experience widely. Within this framework, WPNEM activities focus on identified needs in planning, preparedness and response for the “early” and “intermediate” phases of a nuclear/radiological emergency (including accidents and consequence management for malicious acts), with a view towards preparation of recovery actions. The programme of work is developed in co-ordination with member states and other international organisations

Participants are emergency management experts from NEA countries with recognised knowledge, skills and abilities in the nuclear field. The Working Party employs a flexible approach to address issues across the entire spectrum of nuclear and radiological emergency management, from preparedness to transition to recovery. Participants share information, data, knowledge, and experience to test all aspects of emergency management systems and approaches, identify gaps and provide recommended strategies to improve nuclear emergency management worldwide.

From the beginning, the NEA's focus of work as carried out by the WPNEM has been on improving the effectiveness of international nuclear emergency preparedness and management. Part of its work programme focuses on exploring and developing new concepts and future procedures to enhance national and international preparedness and response management. A key aspect of these efforts has centred on preparing, conducting and evaluating the International Nuclear Emergency Exercise (INEX) series, which has been organised by the WPNEM since 1993. The experiences and lessons learned from these exercises have provided a substantial base for the development of subsequent strategies and recommendations for improving emergency management systems nationally and internationally.

The WPNEM completed the INEX 4 exercise on consequence management and the transition to recovery. On 14-15 October, the WPNEM agreed on the concept of a new exercise (INEX-5) in the series, building on the outcomes of the INEX-4 exercise. Each participating country will conduct a table-top exercise addressing emergency management aspects of notification, communication and interfaces between and among countries and international organisations during the early phase of a release from a nuclear power plant due to a catastrophic natural disaster. The INEX-5 exercise will provide an opportunity for participating countries to test and demonstrate the value of relevant changes put in place as a result of the Fukushima Daiichi nuclear power plant accident.
