Nuclear power is actually really safe. Coal power generation in
India killed a million people in 2019. How many people did nuclear
power kill in 2019? I honestly don't know; but I do know that its way
less than a million. Most people wouldn't bat an eye at the dangers
of building a coal power plant. People aren't good at rationally
considering the dangers of a bunch of low impact events vs one
high impact event.
We've had nuclear air craft carriers and submarines for decades.
Spent nuclear fuel (“waste”) is stored securely in extremely durable,
shielded and sealed containers, not the oil drums shown in this video.
