日本福島3號反應堆的燃料棒可能已全部溶解! 事隔 3年多才向外公佈!

  日本東京電力公司表示,福島第一核電站 3號反應堆的燃料棒溶解程度,較過往評估的更嚴重,所有或接近所有的燃料棒已經溶解,並掉落到安全殼的地面,將令廢棄反應堆的工作更見困難。

  根據東電 201111月最初的評估,溶解的燃料棒為 63%,但如今的新評估卻顯示,反應堆冷凍系統的停運時間,較之前估算早了超過 5小時,因此更多的核燃料掉落到安全殼。即使要清理,也得安排更安全。




Meltdown at Fukushima reactor 3 worse than thought

The operator of the crippled Fukushima Daiichi nuclear plant says the damage to nuclear fuel in one of its reactors may be worse than previously thought.


It says most of the fuel melted through the reactor core and had dropped into the containment vessel by the following morning.

Fukushima reactor 3 meltdown was worse than estimated: Tepco

Tokyo Electric Power Co. said Wednesday that its new estimate shows that all the fuel rods in reactor 3 at the Fukushima No. 1 nuclear power plant apparently melted down and fell onto the bottom of the containment vessel.

In November 2011, the company had said it believed only about 63 % of reactor 3's fuel core had melted.


Fukushima nuclear meltdown worse than initially reported - TEPCO

The meltdown at the Fukushima Daiichi nuclear power plant’s third reactor building was even worse than initially believed, Tokyo Electric Power Co. (TEPCO) has announced.

In fact, the power company’s new appraisal of the Fukushima No. 3 reactor building shows that all – or nearly all – of the fuel rods contained inside were melted, dropping onto the floor of the containment vessel. If true, the news means the power plant could be even tougher to decommission.

According to the Japan Times, TEPCO first estimated back in November of 2011 that roughly 63 percent of the reactor’s fuel rods had melted.
