It is because, as I have, in another thread, given figures that
clearly show nuclear power to be the safest method of power generation
by far

You are barking.

If the rods overheat they will melt down into the concrete below causing a
chemical explosion that will push radioactive materials and dust 50 metres
into the air. The best is yet to come.

No they won't. The last resort of the Fukushima and similar BWR is the 3rd
level containment. Rods melt, captured and dispersed by graphite and held in
concrete designed to cope with the heat until the now dispersed fuel cools.

It's not ideal as the core is now ruined but it is the backup of last resort
and it should be foolproof.
