The photo is almost all waste from all nuclear power plants in Switzerland for the last 40 years. The whole UK produced ~2100 m3 of such waste in 60 years, which is how much a coal plant produces *in one day!*
But it's not all: radioactive decay results in fast decreasing of radioactivity of the waste. In just 10 years it goes down to 30%, in 100 years to 3% etc.
This is why nobody bothered with building underground storage yet - there's too little waste.
