Yeah but i can imagine as we scale the hall like that will soon be able to contain only 10 years worth of material. Then 1 year etc...

That single hall is for the _whole_ country for _decades_.

Nuclear is the _only_ technology where the fuel and the waste for decades can be stored on-site. It's just extremely dense.

The Russians have a single hall for all their waste plus the waste of other countries such as Bulgaria or Ukraine:

The US even had a nuclear power plant with full fuel reprocessing on site:

Just for everyone to have a picture, uranium doesn’t take much room because it is quite heavy: 19.1g/cm3, denser than lead (11.3) but slightly less than gold (19.3) and plutonium (19.8).

The density of uranium is secondary to just how unbelievably energetic (per unit mass of fuel) fission is.

Energy density is the main reason you don't need much volume of uranium. Fission is just extremely energetic.

That c² factor in E = m c² is huge (9 * 10¹⁶).

It is really hard for humans to intuit about factors of ten to the power of 16 or 17.

Your face when people figure out that burning coal produces 100x amount nuclear waste than an average nuclear power plant.

Your face #2 when people realise that this nuclear waste goes to the environment unfiltered.

When our energy consumption increases by 10000 times where will.we store the waste? I am not against the nuclear, I am for it but I like to ask hard questions

Scale what? France already generates all of its own power requirements and is a net exporter of electricity. They're at 100% scale already.

In 2015, the National Assembly voted that by 2025 only 50% of France's energy will be produced by nuclear plants. Source: https://en.wikipedia.org/wiki/Nuclear_power_in_France

The main pertinent local project is an utter disaster, see https://en.wikipedia.org/wiki/Flamanville_3

We could heat the streets in winter, keep all lights on, mine bitcoin, drive around like crazy due to almost free "fuel".

All possible thanks to Nuclear!

If you scale this up you're also having more Area. If that hall contains all the waste from decades of energy for France, I'm sure we can also build 1 in Germany, Italy, and every US state.

That's a nonsensical question, there's not enough nuclear or fossil fuel in the world to increase our energy consumption 100.000x for any significant time period. We'd need to build a dyson sphere.
