The World Nuclear Report:

> Renewables Continue to Thrive

> * A record 165 GW of renewables were added to the world’s power grids in 2018, up from 157 GW added the previous year. The nuclear operating capacity increased by 9 GW6 to reach 370 GW (excluding 25 GW in LTO), a new historic maxi- mum, slightly exceeding the previous peak of 368 GW in 2006.

> * Globally, wind power output grew by 29% in 2018, solar by 13%, nuclear by 2.4%. Compared to a decade ago, non-hydro renewables generate over 1,900 TWh more power, exceeding coal and natural gas, while nuclear produces less.

> * Over the past decade, levelized cost estimates for utility-scale solar dropped by 88%, wind by 69%, while nuclear increased by 23%. Renewables now come in below the cost of coal and natural gas.

That's today.

If you want more research into Nuclear (which has research in the range of hundreds of billions since the 50s) then you need to say: where, what for and with what goal.

Currently it's clear that the investing even more money into nuclear won't bring any breakthrough with visible effects in the next 20 years.

The world will never become carbon neutral with PV and wind turbines. Our needs grow much faster than this tech will, short of an unexpected breakthrough, much like the one nuclear is still looking for and might actually be closer. It's just a great stopgap solution.

Your assumption (mind you, not a fact) that it will never happen does not preclude the investment in nuclear tech. We invested in PV for decades before they became anything near economically feasible. And they're not great for places that don't have the land to spare and/or are far away from the places that do. Not great when you are at the mercy of (ever changing) weather and climate.

But as usual your quotes have nothing to do with my point - that renewables projects can be astonishingly expensive too (nuclear level expensive for some wind turbines) and underdeliver, or that the reason there's no nuclear research has nothing to do with lack of potential but with preconceptions that it must be dangerous. So it's a self inflicted wound where you oppose improving nuclear tech and then you blame it for being old and inefficient. You are part of the reason we don't have good nuclear.

And to highlight the dissonance of your point you insist that there should be no investment in new nuclear tech because old tech is expensive and doesn't scale compared to renewables. And then insist we should invest in new renewables even if they are more expensive and don't scale as well as fossil. How is that? You either invest in the tech that scales and is cheap, or you don't. Or perhaps you invest in the technology that shows promise. And scary-nuclear-label aside, nuclear tech always showed a lot of promise, if only people like you didn't shoot it in the foot and then whined that it's limping.

Just google for "breakthrough in nuclear power" and see what advancements have been made even with a strong opposition of the uneducated. Now imagine what could be achieved if it actually received some solid support. In the meantime we're burning coal.

> The world will never become carbon neutral with PV and wind turbines.

That's your assumption. Fact is: currently only renewable has a chance to make an actual impact for the next 30 years.

> that renewables projects can be astonishingly expensive

That was long ago and in the case of German offshore the reason was that the technology was challenging (because of deep and rough water in the North Sea) and needed to be developed and deployed. Today scaling it is a bit easier and more cost effective. Solar (PV) was also expensive in the first years, but it was always clear that mass-production would bring prices down.

> the reason there's no nuclear research has nothing

There is nuclear research.

> you insist that there should be no investment in new nuclear tech because old tech

No, I insist that there is no need to invest in DEPLOYMENT of nuclear, because the current nuclear has been proven to be a dead end.

> insist we should invest in new renewables even if they are more expensive and don't scale as well as fossil

No I insist to invest in renewables, because they are the cheapest and fastest way to REPLACE fossil.

> And scary-nuclear-label aside, nuclear tech always showed a lot of promise, if only people like you didn't shoot it in the foot and then whined that it's limping.

Nuclear has totally shown its own failure: remember Russia? Worst security. Remember Japan? Fully nuclear. One event took out ALL reactors. Remember the US? No expansion of Nuclear despite having all the technology in the last 30 years. Remember France? A single reactor under construction in last 20 years. Late and cost explosion. 70 years and no storage solution. 70 years and the cost building them is increasing. In the US, in France, ... in core nuclear power countries.

You believe in Santa Claus. Look around. Read the 'Nuclear World Report' and it paints a bleak picture.
