Inaccurate. To take it back to basics:

Radioactive material radiates, because it decays. The more it radiates, the faster it decays. The highest level radioactive material from nuclear fission reactors has half-life measured in decades (30 years), that is, half of it will decay in that time. It does NOT take thousands of years. Conversely, the long-lived isotopes radiate much less, thus are easier to store and process.

    I dont think you read your source quite right. The classification for high level waste is the most radioactive spent fuel, but it is absolutely not safe after a few decades, it decays into still dangerously radioactive isotopes. Maybe you read the part about the dry casques being rated for 40 years but keep reading. They are a temporary solution, and the waste still needs to be buried for tens of thousands of years. Which is a big problem right now because, from your source

    At this time there are no facilities for permanent disposal of high-level waste.

    I did not say it was safe, I said after a few decades is far easier to process. It does not remain "crazy" high radioactive for thousands of years - that is pure hyperbole. The chart attached illustrates radiotoxicity if ingested - and no one advises anyone to eat nuclear waste.

    Ps. There is a country which has solved long term storage. Guess where I live.

    And what you said was still wrong, it still remains dangerously radioactive, and must be stored for tens of thousands of years. Like, youre not gonna find me a source saying this shit doesnt need to be stored for tens of thousands of years.
