[en] The Rotating Target Neutron Source (RTNS-II) at LLL is an accelertor-based neutron source used for studying radiation damage to materials caused by bombarding a solid metal-tritide target with energetic deuterons to produce fusion neutrons. Deuterium continually displaces tritium from the target at rates which currently go as high as 7 curies/h. The addition of a second accelerator and increasing the yield of the present accelerator could increase tritium output to 20 to 30 curies/h. Since it is not acceptable to release this tritium to the environment, a tritium scrubbing system was devised to clean the vacuum system exhaust before it is vented to the atmosphere. The system has been in continuous operation for over one and one-half years. Tritium released from the facility through the scrubber system is typically less than 1 mCi/day
