Message from the Director General
As the Prime Minister Abe told in the Olympic invitation speech, the accident of the Fukushima Daiichi Nuclear Power Station is now in the stable condition, and it is under control. However, it would be dangerous to continue this situation for decades in the future. Therefore, we must properly process and dispose the extremely dangerous radioactive wastes such as fuel debris. The Japan Atomic Energy Agency (JAEA) is only one research organization that has contributed to the industrial application and the development of science and technology through the utilization of radioactive materials and nuclear energy.
The decommissioning of the Fukushima Daiichi Nuclear Power Station is an issue that should be surely accomplished, but it is also extremely difficult to complete this task. For example, it is required to take out and process the fuel debris in the reactor where the radiation level is extremely high, and then safely dispose it. If the debris is small enough to be treated in test tube, JAEA has already technology to safely dispose it. However, considering that the radiation level at the reactor site is considerably high and the amount of total debris is so large corresponding to nuclear fuels in three reactors, we cannot directly apply our technology to the real debris. Under these circumstances, it is necessary to promote the research and development based on various knowledge and experiences.
