Alright, tell me how many more nuclear reactors are needed globally. Let’s just start with decarbonizing electricity production.
And, next, tell me how long do you think that will take, judging based on the average reactor construction time since, say, 1990.
Or look it up, maybe someone wrote an article with such a response.
The best time to build them was decades ago, so clearly the second best time is to… Never? Your argument is taken straight from the oil and coal industries – it would take too long to build up renewables infrastructure, so let’s just not do it? We shouldn’t build windmills, because you can’t tell me how many we need globally?
You’re grasping at straws. If you care about climate change, and you trust in science, there’s only one valid viewpoint on nuclear energy. I welcome dissenting opinions however and would be more than happy to hear why you disagree. Just know that I took courses in college on nuclear reactors and their design as part of my degree, as well as environment engineering, and I currently work in the green energy field – by no means am I automatically correct, but I want to see an argument that’s based in science and recent scientific studies and analysis, let’s say anything past 2015.
I could not disagree more. Renewables are cheaper safer easier to deploy and secure the grid. Nuclear is dead.
Nuclear is the safest energy. It has the fewest deaths per kWh produced. Some modern reactors are able to consume nuclear waste to generate fuel as well. If you want to minimize nuclear waste, we need to build at least some reactors to shove existing waste into.
Nuclear keeps our already unsafe grid more unsafe. It’s too expensive and accidents, while rare, are disastrous. Nuclear is dead.
WTF are you talking about. You can’t just claim it’s unsafe and it makes the grid unsafe. Nuclear is INCREDIBLY SAFE. Other than a few disasters that happened decades ago it has the lowest deaths/kwh. And it won’t help contribute to the BILLIONS of deaths that are coming due to climate change. Your fear of some Chernobyl disaster is irrational.
I’m talking about grid security. https://www.tripwire.com/state-of-security/problem-us-power-grid-its-too-vulnerable-attacks
The solution is decentralization, which for the most part is solar and wind. Ironic that you are learning about this on a decentralized social media platform.

You seem to be unaware of the plans and needs to reduce GHGs. We do not have decades to waste.
You’re right, and that’s why it would be foolish to build exclusively nuclear. It’s also foolish however to not build any nuclear. The long lead time means we need to start ASAP so it’s ready ASAP. With proper government action targeting bottlenecks in the process (I believe there’s only one manufacturer in the world for a certain type of reactor shielding) we can speed that up.
Diversification is the way to go. At the very least, we should build enough reactors and breeder reactors to consume existing nuclear waste and drive that to effectively 0.
On top of all that, the bottleneck for deploying solar and wind en masse isn’t actually solar and wind facilities (although we certainly need those) but our electric grid. It needs an upgrade in order to integrate alternative energies, and I believe estimates on doing that are ~10 years. We might end up in a situation where a nuclear reactor is actually faster to build, depending on the type.
