Kitamura, Koichi; Kutsuna, Hideki; Matsushima, Akira; Koda, Yuya; Iwai, Hiroki

Dekomisshoningu Giho, (51), p.2 - 10, 2015/04

Fugen Decommissioning Engineering Center (herein after called as "FUGEN") obtained the approval of the decommissioning program on February 2008. FUGEN has been carrying out decommissioning works based on its decommissioning program since then. Now is in initial stage, the dismantling works was launched in turbine system whose contamination was relatively low level and their various data have been accumulating. And the draining heavy water, tritium decontamination and transferring of heavy water were carried out safely and reasonably. The preparation for the clearance system and the research and development works for the reactor core dismantling have been progressed steadily as well. Meanwhile, FUGEN has affiliation with local industries and universities for collaboration research, and has exchanged the decommissioning information with domestic and overseas organizations continuously.

The Investigation of the practical use product concerning recycled product that uses clearance metal and trial manufacture

Kutsuna, Hideki

no journal, , 

It is one of the key problems to recycle the material that the clearance is done continuously on the clearance system operation. To grapple with this problem, the recycled product etc. that the nuclear power entrepreneur can use are investigated, and the prototype is produced.

Oral presentation

(1) Plan of Fugen decommissioning, (2) Equipment maintenance, (3) Outline of dismantlement removal construction etc., (4) Preparation situation of clearance, (5) Research and development, (6) Approach and cooperation in local, (7) Approach of Fukushima support, (8) Urgent safety measures etc.

Oral presentation

Preparatory activity for applying clearance system in FUGEN

Kutsuna, Hideki

no journal, , 

Since it is preparing for applying clearance system in Fugen, the performance test of decontamination equipment, clearance monitor's quality assessment, etc. are introduced.

Oral presentation

The Preparation for the clearance system and its operational issues in FUGEN

Kutsuna, Hideki; Izumi, Masanori

no journal, , 

The waste which does not need to be treated as a radioactive material by the clearance system shall be recycled in FUGEN. However the commencing time of the radioactive waste disposal facility operation isn't clear, though, it is important to operate the clearance system and take out the dismantled objects from FUGEN in order to push forward decommissioning as much as possible at the current moment. Although the dismantled objects have temporarily been stored in the facility, the space for the storing is getting reduced year by year. So, the dismantled objects need to take out by the clearance system in early time. In poster presentation, the preparation for the clearance system and its operational issues in FUGEN will be reported.
