Program

Government and TEPCO Council on Mid-to-Long-Term Response for Decommissioning holds International Symposium on Decommissioning of TEPCO's Fukushima Daiichi Nuclear Power Plant (NPP) Unit 1-4 on March 14, 2012 in Tokyo. This event is organized in cooperation with International Atomic Energy Agency (IAEA) and OECD Nuclear Energy Agency (OECD/NEA).

I. Background

On December 21, 2011, Government-TEPCO Council on Mid and Long Term Response for Decommissioning adopted "Mid-to-Long-Term Roadmap towards the Decommissioning of Fukushima Dai-ichi Nuclear Power Units 1-4, TEPCO." The roadmap indicates three phase approach towards 40 years decommissioning period.

In order to realize steady progress of decommissioning, the R&D Roadmap was also discussed and adopted. In the following areas, eighteen R&D projects are identified to address technical challenges for the decommissioning works.

Retrieval of damaged fuel from spent fuel pools
Processing and disposal of radioactive waste
Removal of fuel debris from reactors;
- Development of remote-controlled equipments and devices
- Core status analysis
- Fuel debris characterization and processing

II. Objectives

The primary objective of the international symposium is to foster dialogue and information exchange on current and future challenges to decommissioning of TEPCO's Fukushima Daiichi Nuclear Power Plant Unit 1-4, with a participation of international experts. The goals are:

to identify challenges and technical needs for the decommissioning of Fukushima Daiichi NPP Unit 1-4;
to share relevant practices and experience among domestic and international technical experts;
to explore possible areas for international cooperation to address these challenges.
