IAEA – INTERNATIONAL SEISMIC SAFETY CENTRE (ISSC)

The ISSC was established (Sept 2008) within the IAEA-Department of Nuclear Safety and Security as a global focal point on seismic safety for nuclear installations worldwide.Currently (since July 2009), ISSC is part of the organizational structure of IAEA.According to its established functions the IAEA ISSC is contributing to enhance Member States capabilities to adequately monitor their nuclear installations with respect to site safety related aspects and external and internal hazards, including the engineering aspects of the protection against sabotage.

ISSC – BACKGROUND

• Owing to the complexity of these multidisciplinary problems they should be resolved using the experience and contribution of the whole related international scientific community as well as sharing the lessons learned in order to avoid or mitigate the consequences of such extreme natural events.

Site Safety Review Services

• The objective of the SSRS is to provide upon request from a Member State an independent review and assessment of the site and nuclear installation safety in relation to external natural and man induced hazards and to make recommendations on additional analysis or plant modifications to be carried out in order to comply with the IAEA Safety Standards and to enhance safety.

Site Safety Review Services• A Site and Seismic Safety Review Services (SSRS) is a multidisciplinary review aimed to assess the safety of a nuclear installation site during the complete life cycle of the facility• Currently the SSRS are carried out by the International Seismic Safety Centre within the structure of NSNI while previously were under responsibility of the Engineering Safety Section. • All these safety review services are supported and correspond to the application of a complete and comprehensive set of safety requirements and safety guides documents of the IAEA• SSRS integrates with the Design Safety Review Service, with the Probabilistic Safety Review Service (IPSART) and with the Safety Assessment of Long Term Operation (SALTO).

SITE AND SEISMIC SAFETY REVIEW SERVICES

More than 240 site and seismic safety site and seismic safety review missionsreview missions were conducted since 1980, to ~50 MSs. Site Safety Review Missions in 2009 :• To MSs embarking in NPP site selection: Egypt, Jordan, Vietnam, Nigeria, Tunisia, Belarus, Turkey.

• To others: Iran, Armenia.

IAEA/ISSC INFORMATION SYSTEM AND EXTERNAL IAEA/ISSC INFORMATION SYSTEM AND EXTERNAL EVENTS NOTIFICATION SYSTEMEVENTS NOTIFICATION SYSTEM

267/9/2010 26

The main objective of the “External Event Notification System” is to receive at real time at the IAEA-ISSC, information on the occurrence of external events at the world which could affect operating nuclear installation sites, through a web based online monitoring system. This information may be used as appropriate for communicating with the IAEA staff, the Member States, the public and the media through an adequate product such as an “External Events Notification Report”.
