FIELD: power industry.
SUBSTANCE: chamber pumping is performed until pressure is 10-2 mm Hg, pressure increase is recorded in the chamber at hydrogen evolution and increased pressure is maintained during 60 minutes. During this period, complete decomposition of zirconium hydride occurs, and hydrogen left in zirconium in the form of solid solution is removed at pressure decrease to 10-2 mm Hg.
EFFECT: reducing the time required for hydrogen stripping, increasing the process efficiency.
