Mr. Emanuel Macron’s Government and Presidential Election in 2022 in France
FAPIG No. 197 pp.3 to 8 (2022)

　From the establishment of the government in 2017 until today, the French president Macron has confronted various challenges such as the yellow jacket protest against the planned tax hikes on gas, the strike against the planned pension reform, and the spread of COVID-19. To win a 2022’s next presidential election against Ms. Le Pen and Mr. Zemmour, who get more and more popularity following recent trend of nationalism, obtaining citizen’s understanding on his policies for immigrants and globalization will be a key.

KEYWORDS:Macron, Le Pen, Zemmour, presidential election, yellow jacket protest, pension reform, COVID-19, nationalism, immigrant, globalization

Treatment Results of Receiving / Sorting Facilities for the Interim Storage of the Removed Soil Including Decontamination Wastes
FAPIG No. 197 pp.9 to 14 (2022)

　The removed soil contained in bag is transported to the interim storage facility.
　 In the facility, the soil is taken out from the bag by newly developed bag-breaking device and is divided into groups over 8,000Bq/kg and the other group, using by a newly developed device for measuring radioactive cesium concentration. Two groups of the soil are separately stored in each section of the facility.
　 We report that the actual number of breaking bags as of October 2021 is about 3.6 million and that the accuracy of the device for measuring radioactive cesium concentration is within ± 10%.

KEYWORDS:interim storage facility, receiving/sorting facility, bag breaking technology, radioactive cesium concentration measurement/sorting technology, treatment results

Radioactive Waste Treatment Using the Advanced “SIAL®” Solidification Technology
FAPIG No. 197 pp.15 to 18 (2022)

　Geopolymer has been attracting attention as a solidifying agent for radioactive waste treatment because it is physically and chemically more stable than cement and provides better confinement of radionuclides and heavy metals. Fuji Electric conducted the first demonstration test in Japan using the filter sludge and spent ion exchange resin disposed by nuclear power plants to facilitate the application of the geopolymer based advanced solidification technology “SIAL®”. We confirmed that solidified products filled with radioactive waste up to 40 wt% had higher compressive strength than required for geological disposal. In addition, we confirmed that the partition coefficients of representative radionuclides sufficiently satisfied the configuration values for geological disposal facilities.

KEYWORDS:Geopolymer, Radioactive Waste Treatment

Development of Dustproof / Waterproof / Seismic Switchboards
FAPIG No. 197 pp.19 to 23 (2022)

　For nuclear related facilities including nuclear power stations, the strengthening of the earthquake resistance of their seismic switchboards is required based on the new regulatory requirements effective since the Great East Japan Earthquake, and it has become necessary for them to have a seismic switchboard applicable to newly required facilities such as a facility for dealing with specific severe accidents.
　Fuji Electric has developed indoor seismic switchboards, and pursued the development of seismic switchboards for outdoor use, by working on the strengthening of switchboards. Further, the company has decided to develop a dustproof and waterproof switchboard partly in response to requests for an outdoor switchboard that can be used even in harsh environments in outdoor applications.
　This paper introduces the dustproof and waterproof capabilities of outdoor seismic switchboards, as well as the development of indoor seismic switchboards.

KEYWORDS:seismic switchboards, dustproof and waterproof switchboards, outdoor switchboards
