Is there definitive, authoritative scientific/academic consensus about the sustainability and greenness of nuclear energy?

Sustainable? What do you count as sustainable? Do you consider for example solar power or wind power or geothermal power sustainable? They aren't. If you extract solar power, eventually the sun has ...

Is there definitive, authoritative scientific/academic consensus about the sustainability and greenness of nuclear energy?

No, and it's unlikely there ever will be -- because the risk is just too high and hard to quantify. In the U.S. in the 1950s, the government wanted to encourage the development of a civilian nuclear ...

Why aren't all nuclear plants running at their full installed power to decrease emissions?

TL;dr -- it's most economical to operate nuclear plants at a fixed output level, so other fuels are used to adjust for variations in demand. Nuclear output at any given time is limited by outages, ...

Is there definitive, authoritative scientific/academic consensus about the sustainability and greenness of nuclear energy?

You are asking a couple related questions: 1. Is nuclear fission (that is, existing, conventional nuclear power plants, as opposed to fusion) sustainable? No. The simple reason is that nuclear fuel, ...

What has been the greenhouse gas impact of shutting down Japanese nuclear power plants post-Fukushima?

Change in capacity From 2004 to 2014, nuclear capacity did not change substantially: Change in generation However, the generation mix did change quite a bit (2014 nuclear data not available, so ...

How many square kilometres of offshore wind farms would be required to replace the closing of a 4GW nuclear power station

Your figures are a bit out, but broadly in the right area. Using observed figures for the numbers you've estimated, I get 1,246 kmĀ² 90% capacity factor for nuclear is probably optimistic, but some ...

How many square kilometres of offshore wind farms would be required to replace the closing of a 4GW nuclear power station

Current high-end windturbines (WT) produce about 4.5 MW while being about 240 m high (top of rotor tip) and with a rotor diameter of 150 m. When it comes to the distance between the WT, rule of thumb ...

Can the society label the development of the recyclable nuclear synthesis processes as sustainable and green?

Technetium has been made artificially for decades. It is the lightest element whose isotopes are all radioactive. Because of its relatively short half life, 4.2 million years, and the fact that Earth ...

Is there definitive, authoritative scientific/academic consensus about the sustainability and greenness of nuclear energy?

I would summarize the argument this way: The argument for nuclear power being green is that it doesn't emit carbon dioxide. Also today's nuclear reactors are designed to run continuously with steady ...
