The advantages of the fusion process (although not fully developed) are expected to be.....less radioactive waste and readily available fuel supply? true or false?

Less radioactive waste than...?

Do you mean readily available energy supply?

Since this is not my area of expertise, I searched Google under the key words "fusion advantages" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.

The statement is true. One of the advantages of the fusion process is expected to be less radioactive waste. In contrast to nuclear fission, which produces large amounts of long-lived and highly radioactive waste, fusion reactions produce minimal radioactive waste.

As for the second part of the statement, fusion reactions have the potential to provide a readily available fuel supply. Fusion reactors use isotopes of hydrogen, such as deuterium and tritium, as fuel. Deuterium can be extracted from water, which is abundant on Earth, and tritium can be produced from lithium, which is also widely available. So, in theory, fusion reactors could have a nearly inexhaustible fuel supply.

However, it is important to note that fusion is still a technology that is being developed and has not yet been fully realized on a practical scale. While the potential advantages of fusion are promising, there are still many technical challenges to overcome before fusion can be commercially viable.
