About FNAA


Background

  • Tokyo Electric Power Company (TEPCO) Fukushima Daiichi Nuclear Power Station accident (“Fukushima Accident”) occurred on March 11th, 2011.
    • caused by Great East Japan Earthquake and huge tsunamis
    • Level 7 event classification by the INES(INES Users Manual)
  • Soon after the accident, the Japanese government, research institutions, TEPCO, etc. disseminate a variety of information from their own websites
    • report press release (progress report,
    • photos, movies, raw data (radiation monitoring data, plant parameters, etc)

About FNAA

  • JAEA focused on investing efforts toward the recovery from the accident.
  • In order to collect and preserve comprehensive information regarding to the Fukushima Accident and to utilize in anytime afterward, we started to develop “Fukushima Nuclear Accident Archive (FNAA)”
  • FNAA provide essential information about the accident via the Internet to support the scientific research and development activities.

Issues of the providing the Internet information related Fukushima Accident

  • Lost of link, Disappear of Website, Change of Internet Address
  • Copyright : Permission of the publisher is required to download and transmit Internet Information

To resolve such issues,we’ve extracted Internet information related to the Fukushima Accident from National Diet Library of Japan (NDL) WARP and created their metadata. Access to the internet information has been ever ensured by putting link information (URL of appropriate information in WARP) into the metadata.

Web Archiving Project (WARP) (http://warp.da.ndl.go.jp/info/WARP_en.html) NDL has started WARP since 2010. In this project, NDL collects information in the form of website of the following: the government, the Diet, the courts, local governments, independent administrative organizations and universities.

Apply IAEA Taxonomy for classification

  • IAEA has developed taxonomy for major nuclear accidents
  • Assign more than one of IAEA taxonomy to each metadata to organize the collected information systematically

Provide the reference information via the Internet

FNAA provides useful bibliographies and reports related to the Fukushima Daiichi nuclear power station accident.



Classification of FNAA


All Information in FNAA is classified by using the IAEA Nuclear Accident Taxonomy. The taxonomy is hierarchically structured and here is the six taxonomy whichi is in the highest level.

Please see the IAEA technical Report "Nuclear Accident Knowledge Taxonomy" for the details.

title description
1 LEGAL & GOVERNING FRAMEWORK This topic contains terms related to the overall nuclear governing and regulatory system of a place (country, region) where the accident happened. It includes conventions, laws, regulations, governing structures, instructions applied for normal operation and emergency. The documents and explanations in this topic could help to analyze and understand root causes of an accident which are hidden in the system or boundary conditions, the accidental nuclear facility had to operate in.
2 NUCLEAR INSTALLATION STATUS (NIS) This topic contains knowledge topics on the design of nuclear installations which suffered nuclear accidents, as well as knowledge topics which help to find information on the site conditions and the most relevant information on the operational routines and situation in the operating organization.
3 ACCIDENT MANAGEMENT The section collects information (knowledge) related to the set of actions during the evolution of a given accident:(1)to prevent the escalation of the event into a severe accident;(2)To mitigate the consequences of a severe accident; (3)To achieve a long term safe stable state.
4 EMERGENCY PREPAREDNESS & RESPONSE The session focuses primarily on the response arrangements in case of an emergency, involving fuel damage in the core, spent fuel pools, etc. and indicates how one can be prepared for such an event or what was the level of preparedness of a nuclear installation where an even happened. Unlike session 3, session 4 deals with the emergency situation, not with the mitigation of the accident itself.
5 SCIENTIFIC & TECHNICAL SUPPORT The topic presents information on the scientific & technical support provided typically by R&D or technical support organizations to different stakeholders involved in the nuclear accident management, emergency response and in suppression and liquidation of accident consequences.
6 ACCIDENT CONSIQUENCES (AC) The topic focuses on direct and indirect consequences of a nuclear accident (event). It includes both consequences and measures to mitigate them. It includes effects on peoples’ health, environment, as well as social and economic impacts.
