Nuclear fission is not renewable. It relies on mined uranium, which is rather limited.
The uranium is gonna continue to undergo fission, whether we mine it or not, whether we enrich/refine it or not. At that point it's like collecting energy from our surroundings, really functionally no different than harvesting geothermal, wind, solar, hydro, etc.

In the U.S., unpasteurized cheese must be aged at least 60 days. In theory any pathogens in the milk will make themselves obvious in the finished product.
