Nuclear Accidents Archive - Knowledge Organization System

In line with the IAEA Action Plan on Nuclear Safety, the IAEA was requested to assist Member States in enhancing transparency and effectiveness of communication among operators, regulators and various international organizations, and in supporting wide dissemination of safety related technical and technological information enhancing nuclear safety. In this context, the IAEA was further asked to analyze and preserve lessons learned from the Fukushima Daiichi NPP accident, as well as from other major incidents and radiological events in the past. Identifying, selecting and preserving information related to nuclear accidents and organizing it for accessibility to end users, while ensuring its long term preservation for future generations, has been set as priority by national nuclear authorities of Member States.

There is an abundance of heterogeneous information sources relating to nuclear accidents, including portals and databases and other electronic medium are available out there, particularly on the internet. Moreover, significant information on actual incidents has been reported documented/ collected in different formats and stored in repositories in Member States and at the IAEA. Due to various reasons such as proprietary, political, technical, legal, etc., access to such information is limited which reduces its potential benefit if properly analyzed.

To address this challenge, the IAEA NKM Section has launched a project entitled “Nuclear Accidents Repository Portal Knowledge Organization System (NAA KOS)” , which aims at collecting and preserving data, information, knowledge, and lessons learned from trusted sources related to nuclear accidents and making it available through one single access point, while ensuring their long term preservation for future generations. Knowledge Organizations Systems cover all types of schemes for organizing information and promoting knowledge management. This includes classification schemes, and well-structured vocabularies, such as thesauri and taxonomies, and less traditional schemes, such as semantic networks and ontologies. KOS is to support users finding buried information using sematic technologies and Linked Data. In close cooperation with experts in Member States , the IAEA NKM Section has developed the Nuclear Accidents Taxonomy, which is currently being finalized. This taxonomy will be used, along with other nuclear relevant taxonomies, as the backbone to enhance search and retrieval. NAA KOS would encompass necessary elements and tools to benefit from advanced information technology solutions, including semantic technologies, data mining and linked data guiding the user through a discovery process to identify relevant information without prior knowledge of its existence. The platform would include three areas; Open public area, Restricted area opens to registered users only, and a Collaboration Area to manage and update the Nuclear Accidents Taxonomy.

The overall objective of this initiative is to capture and preserve lessons learned from reliable and trusted sources relating to studies and past nuclear accidents in view of avoiding managerial and technical mistakes. This could assist to find predefined measures in a timely manner that could prevent, or at least minimize the adverse effects of incidents.
