Are We Still Using Uranium Two 35?

Uranium two 38 has a half life of like fiftyes years, not ten thousand years. It doesn't produce crazy, dangerous things that last tens of thousands of years. And it's better because it's not as wasteful rite or dangerous when it gets used exactly. But historically, it hasn't been pursued in the united states due to plutonium and other heavy elements which are also excellent for building nuclear weapons.
