In theory, nuclear power generation may be safe. In practice it is not. There were two major catastrophes that killed thousands, first in Chernobyl and then in Fukushima. Fukushima wasn’t that long ago either. In practice, one should not underestimate the irrational greed of managers. There are calculations of how much damage insurance for nuclear power plants would cost. Since the risk, which can be calculated from the damage multiplied by the probability of occurrence, is very high because the damage in an accident would be so incredibly great that companies cannot afford it and always taxpayers have to save them, which shows the risk the taxpayers bear with nuclear power plants. Many nuclear power plants are very old and extremely expensive to maintain. So you would have to build new power plants in order to install the latest safety technology. Incidentally, the new security technology does not help against invaders either, as can be seen in the Ukraine. This super great security technology is enormously expensive. Renewable energy sources are simply unbeatably cheap because you get the energy from the earth and the sun as a gift. It is already the case that countries with many renewable energy sources, such as Denmark, are depressing the European energy market with their cheap electricity, and conventional energy sources are not getting prices that low. Then there is the biggest problem, nuclear waste. Uranium 235 and its fission isotopes are harmless after 1 million years. So the nuclear waste has to be guarded for 1 million years. Labor costs are bigger than money in the world exists and most countries don’t have repositories because it’s impossible to find a safe place for the next 1 million years. From the generated energy one also has to subtract the large amount of energy that is consumed firstly by the enrichment of uranium in gigantic centrifuges and secondly by the creation of uranium in mining. Only vehicles with combustion engines are used for this and the mining itself emits a lot of CO2. In addition, the uranium deposits are not that large given our high energy consumption. That is why India is researching thorium reactors, but none of them are productive yet. I think fusion reactors are a much better way to spend research money. Nuclear power plants need a lot of water for cooling. In view of the climate change, there were big problems in France last year to cool the nuclear power plants because the rivers did not deliver enough water due to little rain. As a result, many power plants had to be shut down and electricity had to be imported at great expense. By importing uranium from abroad, one also becomes extremely dependent on other countries and on their uranium prices. As you can see, given the huge advances in renewable energy sources, I think nuclear power plants are very poor options for generating energy.
Your premise is specious
There were two major catastrophes that killed thousands, first in Chernobyl and then in Fukushima.
- Chernobyl was a flawed test which deliberately ignored documented safety protocols on an RBMK-1000 high-power channel-type reactor. There are still 10 chernobyl-style reactors operating across russia, but the test method is the primary cause of that disaster.
- Precisely ONE of those 15,000 people killed in Fukushima and neighboring areas were due to destruction of the reactors at Fukushima. Here’s more information.
Firstly you are just picking up on my first point and secondly no one would have been harmed in either disaster if a wind farm had been set up.
I love you. Reddit has that weird cult of nuclear energy bros and I never once saw someone actually successfully stand up to them. I’m never leaving lemmy. 😭
You cannot run a society solely on renewables. You can run a society with zero emissions.
Your first statement is manifestly untrue. We ran societies solely on renewables for over 5000 years. But we certainly can’t run our present society solely on renewables. Actually, I think nuclear energy has an important role in creating a zero emission society; there are places its just too difficult to get renewable energy to with current technology. But it’s not a silver bullet; we can’t run our present society solely on nuclear energy either. We need to be clear-headed about the limitations and, yes, risks of using nuclear energy, so that we can make smart decisions about how to use it and not create another huge environmental problem for our great-grandchildren to deal with.
Many internet nuclear enthusiasts seem to imagine that we could just swap fossil fuels for nuclear energy and carry on our merry way with nothing much changing in society; but that’s not any more realistic than doing that by swapping fossil fuels for renewables. We are never going to be able to maintain our society as it is now without fossil fuels; things will have to change in a very big fundamental way. I’ve observed that nuclear energy enthusiasm on reddit has tended to act as a form of climate quasi-denialism. Misguided faith in a tech solution that will just fix everything without major social repercussions ultimately prevents us from acknowledging the difficult and unpleasant reality that large structural change is necessary, change that will inevitably impact the standard of living of people in wealthy countries for the worse.
