10th ANNIVERSARY OF THE INTERNATIONAL NUCLEAR EVENT SCALE (INES)

摘要

During the 80's effective communication between the nuclear community and the public and media became an important factor for further sucessful development of nuclear power programmes in many countries. This need was felt mainly in the communication of incidents or accidents at nuclear or radiation facilities. The Chernobyl accident in March 1986 confirmed this fact in a very dramatic way. For this reason several countries (France, Japan, UK) initiated the preparation of a scale for the classification of events. In 1989 the IAEA and NEA/OECD jointly started the development of an international scale, which could be used to improve the effectiveness and consistency of communication of the significance of nuclear and radiation events to the public and the media. In 1990 the International Nuclear Event Scale (INES) was put into trial operation In 1992 the INES User's Manual was officially published and INES became a tool used to communicate information regarding nuclear and radiation events world-wide on an official level. The INES Advisory Committee was established to review event ratings and to make proposals for further improvement of the scale. During regular annual meetings of participating countries the INES National Officers relate their experience with the application of the scale. In 1998 the participating countries decided to issue an updated INES User's Manual, which will represent the experience accummulated with the scale over the past ten years. The new manual is planned to be published in 2000.
