Okuma Analysis and Research Center

Greeting from the Director General

Thank you for visiting the homepage of Okuma Analysis and Research Center.

In the Okuma Analysis Research Center, JAEA is preparing the "facility for analysis and research of radioactive materials". In the facility, we will conduct analysis and research to clarify the characteristics of radioactive wastes and fuel debris produced by the accident of the Fukushima Daiichi Nuclear Power Station.

The data obtained by the analysis and research will be utilized to establish the method for steady disposal of radioactive waste and the basic technology concerning the safety of waste disposal towards the decommissioning of 1F.

The facility for analysis and research of radioactive materials consists of three buildings; Administration building, Laboratory-1, and Laboratory-2. The Administration building mainly used for the office of the staff started in operation in March 2018. The full-scaled construction of the Laboratory-1 is now under way, where medium- and low-level radioactive wastes will be analyzed. The detailed design of the Laboratory-2 is now in progress, where fuel debris will be analyzed.

The 1F is the first reactor that caused the severe accident in Japan. Therefore, we have to develop the technological measures for the storage and disposal of radioactive waste and fuel debris towards the decommissioning. Since the characteristics of the fuel debris in the 1F are different from those in the Three Mile Island or Chernobyl, it is essential to clarify the nature of the debris by the careful analysis for its safe treatment.

Since our facility is unique in the world, its design and construction are very challenging. All of the staff are working with the strong desire to contribute to the safe and reliable decommissioning measures of 1F. This experience is very valuable for us as technologists. We would like young people inside and outside JAEA to actively participate in our project. Thereby, the results will lead to the technological improvement as all Japan.

I would like to ask for your continued guidance and support for our activities in Okuma Analysis and Research Center.

Outline of the Center

The Okuma Analysis and Research Center is a facility where the analysis and research are conducted to clarify the characteristics of radioactive wastes and fuel debris that were produced by the accident of the Fukushima Daiichi Nuclear Power Station (1F), Tokyo Electric Power Company Holdings, Inc. The Center consists of Administration Building, Laboratory-1, and Laboratory-2, and it is located near the 1F.

The data obtained by the analysis and research will be utilized to establish the method for steady disposal of radioactive waste and the basic technology concerning the safety of waste disposal towards the decommissioning of 1F.

In order to avoid the radiation exposure to the workers, the analytical works are carried out using iron cell with the shielding function and remote-control instruments (manipulator etc.). Glove boxes that enclose radioactive materials are also used to avoid the internal exposure.
