Advanced Thermal Reactor “FUGEN” is the heavy water-moderated, boiling light water-cooled, pressure tube-type reactor. The commercial operation of this reactor started in 1979 and terminated in 2003. We have been dismantling the facilities based on the decommissioning program since 2008.
Except for reactor core and heavy water system, the periphery system of FUGEN is similar to the BWR.
Therefore, the results of decommissioning in FUGEN will be reflected to the decommissioning of commercial reactors in the future. In Japan, we play an important role as a pioneer for decommissioning of the other reactor owned by electric power companies.
Since it is important to reduce the amount of low-level radioactive waste generated as a result of decommissioning, an attempt has been made since 2008 to apply clearance system to a portion of this waste.
Subsequently, decontamination and measurement data associated with the clearance were compiled and evaluated. As a result, we confirmed that the clearance operation of the turbine facility has started and has been progressing smoothly since then. We will obtain decontamination and measurement data in order to reflect them to the next own works and other decommissioning plants [1].
