Description
Some radionuclides are isotopes of elements that are either gaseous or form volatile compounds at relevant temperatures and pressures. Gaseous elements, e.g. Kr, will be lost from HLW during vitrification. Of the fission products and activation products, only carbon is expected to be capable of forming (organic) volatile compounds. Isotopes of radon will be produced by radioactive ingrowth over the course of time.
