Russia’s Medvedev to make anniversary trip to Chernobyl

Chernobyl: 25 years since the nuclear disaster

 

Russian President Dmitry Medvedev will visit Chernobyl on Tuesday to mark the 25th anniversary of the worst nuclear disaster in history.

“I will go to Chernobyl tomorrow,” the Russian president said on Monday during an award ceremony in the Kremlin for participants in the clean up operation of the 1986 disaster.

The area around the Chernobyl plant, about 150 kilometers (93 miles) from the Ukrainian capital of Kiev, remains highly contaminated from an explosion at the plant’s reactor number four a quarter of a century ago.

The partial meltdown of three reactors and at least two spent fuel pools, along with multiple hydrogen explosions at the site now rate a 7 on the International Nuclear Event Scale—a level previously affixed only to the meltdown and explosion at Chernobyl.

Fukushima is now officially a “major accident” per the scale—roughly 100 times worse than the worst civilian nuclear accident in the U.S.: the partial meltdown at Three Mile Island—constituting “a major release of radioactive material with widespread health and environmental effects.”

Fukushima é a causa de um novo dilema brasileiro: aumentar ou não a oferta de energia nuclear

Felipe Prestes

O país não pode manter um crescimento econômico como o do ano passado (7,5%), sem expandir consideravelmente a oferta de energia. Para isso, são necessários investimentos de cerca de R$ 1,3 trilhão em infraestrutura de energia, nos próximos dez anos, sendo que o país deverá estar atento aos impactos sociais e ambientais desta expansão. No entanto, neste momento em que o Japão sofre com os vazamentos ocorridos na usina nuclear de Fukushima, surge um novo questionamento: vale a pena expandir a oferta de energia nuclear?
