I just looked up danger of spent fuel rods. 10000 years. But not to worry
Our government is looking after them. The same government that can't keep our highways repaired for 100 years but thinks a stupid fence will stop drugs coming into the country. Keep watching fox propaganda.
The spent fuel rods are indeed radioactive for a very long time. The (very small) component of plutonium has a half Life of about 20,000 years ( there are actually two isotopes,; one with a 24,000 year half life, the other with a 14 year half life.)
We could easily reprocess the spent fuel; reducing the waste volume and radioactivity by almost half and recovering other usable fuel in it. Our Navy does that with the spent fuel from its nuclear powered ships, and I believe France, Britain, Japan, Russia and China all do that with their spent fuel from nuclear power stations.
In either case the volume of the high level waste is very small. All of the high level waste produced by Nuclear power generating stations in this country since the late 1960s would fill a football field about 3.5 feet deep. That's not a big engineering problem.
The total spent fuel from the two 500MW reactors in a Nimitz class aircraft carrier - after 50 years of designed operation - is about 600Kg. The associated environmental insult of this is trivial, compared to other power sources. Commercial reactors use fuel that is less enriched, and therefore yield a greater volume of waste. However that is a simple design/cost tradeoff. More enrichment of the Uranium fuel = less high level waste.
My company recently completed a large asbestos contaminated soil removal at a site in Oregon. We removed (and transported to a waste dump) enough soil to fill that football field 180 feet deep. In comparison to that, the 3 foot depth of the high level nuclear waste is a relatively trivial engineering problem.
