E-poster T3.2 Radionuclide Technologies and Applications Lightning talks: P2.2, P3.2, P3.6

Xenon International is a next generation radioxenon monitoring system that was developed at PNNL and being manufactured at Teledyne Brown Engineering (TBE) to strengthen nuclear test monitoring and has recently completed Provisional Technical Secretariat (PTS) testing and was accepted as a qualified system for the International Monitoring System (IMS). Xenon International processes samples every six hours generating over 2.5 cc of xenon gas that is counted in a beta-gamma coincidence detector for 12 hours resulting in unprecedented detection limits for radioxenon isotopes. Phase 1 testing was conducted at TBE and Phase 2 was conducted at Schauinsland Germany at RN33 radionuclide station. Xenon International completed acceptance testing with >96.93% uptime, and routinely detected never-before seen radioxenon isotopes in an IMS station including Xe-125, Xe-127, and Xe-129m during Phase 1 of testing. This talk will discuss Xenon International performance during PTS testing and will discuss expected and unexpected radioxenon isotope detections.

Promotional text

The work cited in this presentation fosters strengthening nuclear test monitoring though development of advanced radionuclide detection systems. Xenon International strengthens remote monitoring of nuclear explosion, data interpretation, and data availability of complex systems.
