核反應堆如果完全融解會有幾嚴重?

Chernobyl disaster

當時死了4000, 有1,000,000 因為咸核而cancer 死,而家方圓200miles 冇人住, 估計核污染多100年...

自己睇...

The serious of consequence of a reactor core-melt accident depends very much on whether there is any breakage on the confinement.

There are three nuclear reactor accidents that involve core-melt so far in the history of nuclear power, of these only two involve commercial nuclear power stations. The one at Three Miles Island in the US in April 1979 and the one at Chernobyle in May 1986 (there is another one occurred in October 1957 at Windscale, UK, but the reactor is for military purpose).

The reactor at Three Miles Island, which was a pressurized water type reactor (same type as the one used at Daya Bay) underwent a core-melt during the accident, but there was no breakage of confinement and the radioactivity released is limited. The average dose to an individual within 50 miles of the reactor site was estimated to be 10 micro-sievert, which is below 1% of the natural radiation background.

The one in Chernobyle was the most series one. The reactor involved is a RMBK type which only had very weak confinement. As such, the heat produced from the core-melt thrown all radioactivity into the atmosphere. It has been estimated that the dose to persons evacuated from the affected area ranged from 33 000 micro-sievert to 300 000 micro-sievert.

Therefore, a core-melt accident may not necessarily lead to a catastrophe.

如果係核電廠既話
個反應爐融解既話
就好似1986年既切爾諾貝爾核災難做例子
近3000度左右既溶融狀態放射性元素釉同銫會一直流穿地下
直至地下水源,會引致污染全國水源
所以當年蘇聯設法係切爾諾貝爾核電廠到起個用水泥做既COVER蓋住佢
之後仲係其他反應爐到挖一條隧條係意外發生反應爐下面放液態氮
希望可以降溫
嚴重既,隱瞞事實最壞結果全世界都中輻射

咁就要視乎你個堆有幾大堆LA.
