The high-pressure gas facility for the tandem accelerator at nuclear science research institute is the facility to transfer SF
gas between the accelerator and gas storage tanks. The SF
gas is used to keep high voltage insulation of the tandem accelerator. This facility is one of the largest SF
gas handling facilities in research laboratories. This facility has been operated for 31 years. In addition to regular maintenance, we have evaluated the deterioration due to aging. SF
gas is regarded as a kind of green house gases that causes global warming and it is strongly required to reduce such gas emission into the atmosphere in recent years. In JAEA, the reduction of gas the emission is also an important problem. We have been continuously taking action for reducing the emission of SF
gas. In this article, we report the records of maintenance, evaluation of aging, and activity of reducing SF
gas emission.
