New Nuclear Reactor Design
One of the significant lessons learnt from the Fukushima Daiichi nuclear accident is that the current nuclear reactor has no means to contain fuel being melted down.
Accordingly, my idea is to provide a huge water tank beneath the container vessel which holds a pressure vessel where uranium fuel rods are set and water is circulated to/from a turbine room.
If a meltdown and melt-through occurs, melted uranium will be cooled down while it is gradually falling in the huge water tank installed just below the containment vessel.
As it will take some time for water filling this tank to evaporate, emergency work will have enough time to prepare and pour additional water into this tank. So, if an accident should occur and uranium fuel should melt down and melt through the bottoms of the pressure vessel and the container vessel, staff can concentrate on emergency work to pour water into this tank.
If the reactor units of Fukushima Daiichi which underwent a meltdown accident had had this sort of huge underground water tank, no huge amount of leakage of radioactive material should have occurred.
Any existence nuclear reactors in the world should be equipped with this underground counter-meltdown water tank. The costs for this reactor upgrading work will be just $100 million or so.

It is to admit the limit of his own power and ability before somebody such as an enemy the God or the Archenemy set up before him, maybe.
