中国：台山原発の燃料棒破損と発表：放射性希ガス拡散（動画）：
China:Damage to fuel rods at Taishan nuclear power plant:Radioactive gas:
中国：宣布泰山核电站燃料棒损坏：放射性惰性气体
ー放射性物質の濃度が上昇ー
【北京共同通信】
中国広東省の台山原発から放射性希ガスが大気中に放出された。
問題が起きたのは台山原発1号機の原子炉内。
「燃料棒のうち5本前後」が破損した。
中国生態環境省：
6月16日、台山原発の燃料棒の破損により、冷却材中の放射性物質の濃度が上昇したと発表した。
情報公開を求める国際世論に押され、問題が起きたことを初めて認めた。
技術や安全面の基準は満たしていると強調している。
中国は、「海外メディアが指摘するまで、情報を公表していなかった」とのこと。
中国は原発拡大路線：
中国は原発の拡大路線に傾いており、管理の不透明さに懸念が強まりそうだ。

China Taishan plant: ‘Performance issue’ reported at nuclear facility
What went wrong at the plant?
EDF said
there was a build up of noble gases in part of the cooling system of the plant’s number one reactor.
The gases
were collected and treated before being released into the atmosphere in “accordance with regulations”.The Taishan plant
provides power for the Guangzhou and Shenzhen areas, both major manufacturing hubs.The unnamed spokesman told AFP
the gas leaked after the coating on some of the fuel rods deteriorated.
Fuel rods are sealed metal tubes
which hold nuclear materials used to fuel the nuclear reactor.Noble gases – also known as inert gases – are a group of stable chemical elements which have very low reactivity.
They are often used in situations
where scientists do not want chemical reactions, for instance in nuclear reactors or lighting.AFP news agency reports
the gases released were xenon and krypton.The International Atomic Energy Agency (IAEA)
announced it has “no indication that a radiological incident occurred”.
The agency, which is the UN’s nuclear watchdog, said it had contacted counterparts in China about the issue.
EDF Energy
also announced on Monday that it had called a meeting of the plant’s board.China Guangdong Nuclear Power Group told state outlet the Global Times that
the nuclear plant has operated the reactors strictly in compliance with business licence documents and technical procedures.
