Come smaltire le acque radioattive di Fukushima?

 

An aerial photo shows Fukushima Daiichi nuclear power plant in Okuma town, Fukushima Prefecture in January, 2021. The Japanese government has decided to get rid of the massive amounts of treated but still radioactive water stored in tanks at the wrecked Fukushima nuclear plant by releasing it into the Pacific ocean, a conclusion widely expected but delayed for years amid protests and safety concerns. Prime Minister Yoshihide Suga on Wednesday, April 7, 2021, told top fisheries association officials that his government believes the release to sea is the most realistic option and a final decision will be made “with days.”(Kota Endo/Kyodo News via AP)

People chant slogans against government's decision to start releasing massive amounts of treated radioactive water from the wrecked Fukushima nuclear plant into the sea, during a rally outside the prime minister's office in Tokyo Tuesday, April 13, 2021. The decision, long speculated but delayed for years due to safety concerns and protests, came at a meeting of Cabinet ministers who endorsed the ocean release as the best option.

People hold a banner that partially reads

Il governo giapponese ha deciso di iniziare il rilascio nell’Oceano Pacifico delle enormi quantità di acqua radioattiva conservate nei dintorni della centrale nucleare di Fukushima, distrutta da terremoto e maremoto l’11 marzo 2011. Questa decisione è fortemente contestata dagli ambientalisti, dai pescatori e dai residenti locali, che temono per l’inquinamento delle coste e la contaminazione dei pesci, tenuto anche conto che una vasta area di territorio intorno alla centrale non è mai ritornata alla vita normale.

La decisione sullo smaltimento delle acque radioattive è stata ritardata per dieci anni a causa delle preoccupazioni e delle proteste per la sicurezza, ma è diventata sempre più urgente perché l’acqua inquinata non può essere mantenuta indefinitamente nelle grandi cisterne intorno alla centrale. Il governo sostiene che il rilascio nell’oceano sarà graduale, diluito nell’arco di due anni, per cui non aumenterà in modo significativo il livello di radioattività naturale delle acque (AP Photo / Lee Jin-man)
