What could make nuclear gases not destroy the ozone layer?

Question

for science

Answer 1

Nuclear gases?   The only gases that destroy the ozone are CFC's Chloro-flouro-carbons.  They have been banned in most civilized nations.  Nuclear gases?!  I'm a nuclear engineer and I don't even know what you mean by that!

The only "gas" that comes out of a nuclear reactor is water vapour... ya know... the stuff clouds are made of?

Answer 2

If nuclear gases are hydrogen or helium or water vapor, then they should not destroy the ozone layer.
