I see that E+T is reporting the same problem:

'Challenges include thousands of design changes demanded by regulators, inflation, disruption to supply chains and labour shortages.'

Hi Roger,

This nuclear safety problem is worrying me as we know that nuclear submarines have sailors living for a whole year within metres of a nuclear reactor and seem to be unharmed??

Further, we read that uranium fuel rods can be safely stored under water in tanks on the power station site.

Someone needs to write a paper on why we need more reinforced concrete I think.

The water thing is quite fun, This article is a bit tongue in cheek but the figures referred to and used to make the calculations are  correct.

It implies we were not so easily scared we could save a lot of money on heating swimming pools by giving them a few dead fuel rods each in a keep-out cage at the bottom ;-)

As you are supposed to plan for a maximum exposure of 1/3 of the limit it would not be possible to build a nuclear power plant in Cornwall
