How many plutonium do we get every year from the nuclear plants?

Into eternity: The nuclear waste challenge

The timescale for keeping hazardous nuclear waste isolated from living organisms is unimaginably long, with times specified by nuclear regulators in Europe and the USA ranging from 10,000 to 1,000,000 years. Who knows what the human race, or indeed the planet, will be like 40,000 human generations from now.

Already, the world’s nuclear power plants, which generate around a fifth of global electricity, have yielded in excess of 300,000 tons of high-level nuclear waste, a figure that will dramatically increase in the context of a world nuclear renaissance. Most of the waste is currently stored above ground in spent fuel pools or dry storage. But, as the Fukushima accident in 2011 showed, above-ground nuclear waste storage is vulnerable and there is broad agreement among nuclear-generating countries that the best option is to bury it deep and inaccessibly in the Earth.

Understanding how to keep nuclear waste safe is clearly a considerable challenge, one that new research led by the University of Cambridge aims to help solve through fundamental studies of how nuclear materials behave, and are likely to behave, over massive timescales.

Ok! Thanks!
Is there maybe a knowledge by you about the existence of plutonium inside of our Earth, coming out of nuclear processes, which happen in the inner earth continuusly as usual? Does it exist - plutonium in the inner earth???
When yes, which reactions could be observed?? Some link?
