Except for funding, obviously.
And as I said, the main point is we need clean, renewable energy as soon as possible, which only solar and wind (and to some extent hydro) can provide.

If you read my comment, I specifically add a caveat for hydro.
In terms of solar and wind, of course we cannot just build unlimited amounts, but we can ramp up capacity a lot more easily and quickly than with nuclear, because it’s a lot simpler and faster to build (especially solar). Imagine if we increase construction capacity by 10x tomorrow; we would still need to wait for 15 to 25 years to see any impact with nuclear, while solar and wind would go online next year.
Of course, ramping up production brings an increased risk of manufacturing faults and construction errors in all cases. But I would argue that any nuclear accident is a lot more undesirable than some solar or wind power going offline.
In terms of nuclear fuel, these alternative technologies may exist. But again, the time to market, and the fact that we are introducing a new technology into our vastly expanding production capacity just brings even more risk and uncertainty, which is completely unnecessary when extremely save and reliable, well tested alternatives exist (solar and wind).
So what I am arguing is that we focus our limited resources and money (the latter being the key factor in our economy, unfortunately) on the things that have the largest impact in the shortest amount of time, and that is solar and wind (and to an extent hydro).
And again, all that analysis is graciously disregarding the very real risks of nuclear power (instability, war, proliferation).
That is a very interesting report, thanks!
Reading through the summary and overview, they address exactly the problem that I’ve highlighted: how can we build more reactors faster and more economically, without compromising safety? Of course that means that this issue remains unresolved for now, underscoring my point.
They avoid discussing the other risks I’ve mentioned (stability, war, proliferation) and admit as much, which is fair enough, but I cannot find any comment regarding the availability of fissile material in the supply chain, which I would think is a rather crucial point.
What I take away from this report is that Nuclear power has a place in solving the climate crisis, if we:
All in all, they conclude that sweeping changes are needed (which is always a risk) and disregard crucial present and known risks. Both these points are simply non-issues with solar, wind, and hydro-power.
I will have to strongly disagree here. The timelines are actually the main reason why I would disqualify Nuclear power as a solution to energy, even as a temporary one.
The time from inception to going online for a new Nuclear reactor is in the range of 15-25 years. Of course we could attempt to shorten that, but that would probably mean compromising on safety. So indeed, if we want to stop using fossil fuels asap, building solar, wind, and hydro, which come online in a matter of months (maybe years for hydro), is much faster.
Aggravating this are two further issues: Current Nuclear energy production is non-renewable, and supply problems are already known to occur at current energy production levels. Second, the global construction capacity is limited, probably to around current levels. Even if we do not push for faster construction times, the number of companies and indeed people who have the necessary expertise are already at full capacity, and again, expanding that would probably imply safety problems.
That is to say, currently running Nuclear power plants are save and clean, so by all means keep doing it until renewables take over. But expanding Nuclear power to solve the energy problem is a non-starter for me, due to the timeline and it being non-renewable. And that is before we start talking about the very real dangers of Nuclear power, which are not operational of course, but due to proliferation, war, and governmental or general societal instability (due to say, climate change).
Yes, this might prompt the harshest reaction in decades: a letter with a stern condemnation. But I wouldn’t count on it.
I totally agree that current nuclear power generation should be left running until we have enough green energy to pick up the slack, because it does provide clean and safe energy. However, I totally disagree on the scalability, for two main reasons:
Current nuclear power generation is non-renewable. It is somewhat unclear how much Uranium is available worldwide (for strategic reasons), but even at current production, supply issues have been known to happen. And it goes without saying that waiting to scale up some novel unproven or inexistent sustainable way of nuclear power production is out of the question, for time and safety reasons. Which brings me to point 2.
We need clean, sustainable energy right now if we want to have any chance of fighting climate change. From start of planning of a new nuclear power plant to first power generation can take 15 or 20 years easily. Currently, about 10% of all electricity worldwide is produced by about 400 nuclear reactors, while around 15 new ones are under construction. So, to make any sort of reasonable impact, we would have to build to the tune of 2000 new reactors, pronto. To do that within 30 years, we’d have to increase our construction capacity 5 to 10 fold. Even if that were possible, which I strongly doubt, I would wager the safety and cost impacts would be totally unjustifiable. And we don’t even have 30 years anymore. That is to say nothing of regulatory checks and maintenance that would also have to be increased 5 fold.
So imho nuclear power as a solution to climate change is a non-starter, simply due to logistical and scaling reasons. And that is before we even talk about the very real dangers of nuclear power generation, which are of course not operational, but due to things like proliferation, terrorist attacks, war, and other unforseen disruptions through e.g. climate change, societal or governmental shifts, etc.
I faced a similar challenge a few years ago; from my own projects to a large policy management system at an insurance company with literally 100s of thousands of source code files.
Of course it was extremely daunting at first, but what definitely helped me most was coming up with a strategy to find code where similar things had already been done.
This is easiest with a good IDE (search for aptly named classes, functions, etc.), and of course then asking somebody more experienced if you found the right bit of code. The last point cannot be overstated; most people love to show off their knowledge. If you come to someone with a question about a specific piece of code, they are usually extremely helpful. And importantly: if you don’t know who to ask, simply ask someone whom to ask! Again, make people show off their knowledge.
What does “mastering it” really mean? Usually a big part is learning from mistakes. Which I do not think is something you want to do with nuclear power.
