In this paper, the transit temperature field and thermal stresses of hold structures of a single side shell and double bottom vessel were analyzed.

If the temperature is high enough, the core slumps to the bottom of the reactor vessel and melts through it and onto the floor of the containment unit.

如果温度高到一定程度，堆心就会落到反应堆容器的底部并将其熔穿，从而到达密封装置的底部。

Some of the salt might be settling to the bottom of the reactor vessel rather than sticking to the fuel rods.

部分盐也许会沉入反应堆容器的底部，而不会粘在燃料棒上。

The result, after several days, was a sludgy brown stain at the bottom of the reaction vessel a stain that proved to contain amino acids.

That is a very different situation than at Fukushima Daiichi, where the fuel in three reactors is thought to have burned holes in their immediately surrounding pressure vessels, and in one case to have fallen all the way through to the bottom of the outer containment vessel.

Two explosions on board the submarine had been monitored, making it clear that the bow of the Kursk had been ripped open, and the vessel had sunk to the bottom like a stone.
