The only thing that matters in reality is the investors making a profit. If nuclear out competed other generation on that basis it would be everywhere now, regardless of whether it was safe or not. cf Hydroelectric. A dam destroys more land for a far longer time than Fukushima has left contaminated today. And as for deaths, dam failures have a truly horrifying track record: https://en.wikipedia.org/wiki/Dam_failure https://en.wikipedia.org/wiki/Dam_failure 100 people died just building the Hover dam. Yet we are likely to see more Hydro, not less. You don't see nuclear for one reason: it's high risk with low returns. It isn't high risk because nuclear reactors regularly go bang. It's high risk because a plant has to operate profitability for 40 years in order to make a return, and 40 years is too far out so safely predict anything. 40 years ago there was no internet and global warming wasn't something we knew about. The plant going bang is just one of many things that could render it unprofitable. There could be fuel supply problems (cf Iran), or the demand could move away (eg, a aluminium smelter could close down), or a cheaper technology could come along, or an earth quake, or a tsunami. The new designs in the article seem to solve some problems. Being tow-able means if the current market folds you can move it somewhere else for example, and being small means there is less money at risk. But geezzz - 4 years to build. In 4 years it is possible the price of solar or wild could drop by 40%.
