At Chernobyl it was:

1) ignorance of the possible behaviour of the reactor when run outside its
normal operating envelope, combined with removing or shutting down all the
computers and other safety equipment so the reactor could be forced into what
turned out to be a dangerous and unstable mode.

2) Poor operating procedures for running this sort of reactor test

3) Poor emergency procedures and lack of coordination with local fire
services.

4) The usual communist culture of secrecy which led to delays and made the
problem worse.

At Fukushima it was:

1) The assumption that the sea wall could contain the tsunami (they were
nearly right on that one).

2) Not siting the backup power generators and their fuel tanks where they
wouldn't be overwhelmed by a worse rsunami.


Hindsight is such a wonderful thing.

Not only can it tell us how mistakes we made the past could and should have been
avoided, but it will also be able to tell us how mistakes we are inevitably bound
to make in the future, could and should have been avoided as well.


We have moved on to passively cooled reactors, so that loss of power, fans, pumps,
electricity, generators, etc. are not a problem.

That eliminates the common risks of external problems.


Neither the Russians nor the Japanese were, or are, particularly stupid.

In pointing out the "mistakes" that they made Tim Streater is merely reinforcing
the point - of how easy it is, without the benefit of hindsight for people who aren't
particularly stupid to make "mistakes".

And that basically there's no reason to believe that people, who aren't particularly
stupid aren't going to continue making mistakes in the future of a kind and in areas
we can't even predict. The possible consequences of which may be similarly
difficult to predict.
