A prototype continuous vent gas sampler for monitoring uranium and technetium emissions from the Portsmouth Gaseous Diffusion Plant has been developed and extensively tested. Based on the results of laboratory tests and field use, a sampler of the prototype design will provide: acceptable accuracy for the continuous and automatic sampling of radionuclide emissions for vent monitoring purpose; capability to significantly extend detection limits for uranium and /sup 99/Tc concentrations in plant vent gases using existing, well-established analytical methods; and reliable operation and minimal maintenance. In addition, the continuous sampler is an attractive alternative to replace grab sampling since it: offers a potential cost savings estimated at 200K/year; allows more convenient storage of samples for archival purposes and retrieval, if necessary; and is a more flexible means of meeting alternative monitoring needs with the requisite accuracy and frequency of results. Design criteria have been established by this work and are being used for engineering continuous samplers for permanent installations. 3 references, 3 figures, 3 tables.
