Amount of high level Nuclear Waste

[bigjoemonger]

I'm writing a paper basically advocating that we should build more Nuclear Power Plants to cover increasing energy demands and to replace outdated fossil fuel facilities.

I'm reading this webpage and it says that the total amount of High-Level radiation waste for the US Nuclear Industry over the last 4 decades would cover a football field about 7 yards deep.

I'm wondering, is that considered a lot? Because the US is a big place with about 100 active Reactors and over 40 years it doesn't seem to me like 72,000 tons is a lot.  Especially considering Fossil Fuel Plants produce waste on the level of 100,00 tons or more every year.

Any input is appreciated.

I'm wondering, is that considered a lot?

I have to ask, is that a lot of what?
A lot of waste?  Not really.
A lot of investment for a reprocessing industry? Yes.
A lot of problems in the current configuration? Maybe.
A lot of work for a skilled work force? Maybe.
A lot of material for politicians' speeches? Absolutely.
