Uranium is dissolved in seawater, which can be extracted [1]. When the portion of uranium in seawater drops, more uranium in the crust gets dissolved into seawater. It's estimated that about 100 billion tons of uranium can be extracted in this method, enough to power humanity for millions of years [2]. If you want to get pedantic, there is a finite amount of fissile material. But the same applies to solar power: there's a finite amount of hydrogen in the sun. Entropy dictates that energy is finite, thus there's no such thing as a truly renewable energy source. 1. https://www.pnnl.gov/news/release.aspx?id=4514 https://www.pnnl.gov/news/release.aspx?id=4514 2. https://www.forbes.com/sites/jamesconca/2016/07/01/uranium-seawater-extraction-makes-nuclear-power-completely-renewable/ https://www.forbes.com/sites/jamesconca/2016/07/01/uranium-s...
