Yes, that is where we get the nuclear material for our reactors, by mining it from the Earth. Though it does not occur in high concentrations, we have to concentrate it ourselves.
90 occur naturally - others have been made in nuclear reactors etc
Nuclear fusion is the process that powers stars, such as our sun.
It DOES occur naturally. It is an ore. It is not man made.
We look to the naturally occurring element uranium as a nuclear fuel.
The main consequence is the production of quantities of highly active fission products which would not occur naturally, and which will have to be carefully stored for thousands of years.
Nuclear envelope
A nuclear disaster may occur when the radioactive materials are mishandled and which may lead to radioactive exposure or a chain reaction of nuclear fission, fusion. Most of these disasters are induced by the man made mistakes.

In nuclear science, transmutation is where one chemical element or isotope is converted into another. It occurs when materials decay, or it can be caused by nuclear reaction.
Nuclear fusion is the process that powers stars, such as our sun.
Synthetic materials are any materials that do not occur naturally and are man-made, usually by chemical processes. These can include a huge range of materials including plastics, nylons, ceramic materials and even some metals.
It DOES occur naturally. It is an ore. It is not man made.
We look to the naturally occurring element uranium as a nuclear fuel.
Nuclear fusion in the stars
Thallium, discovered in 1861, does occur naturally, but not in its pure form.
There are 119 currently known elements. 98 of them occur naturally, with the remainder created in particle accelerators or during nuclear reactions.
