Continuous vent stack sampling for monitoring of radionuclide discharges is required under the National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations of the Clean Air Act. At Portsmouth, fourteen vent stacks with the potential for release of radioactive discharges that could cause an effective dose equivalent of greater than 0.1 mrem/yr. to the public have continuous samplers installed to measure radioactive discharges. A continuous sampler consists of a point source radionuclide extraction system that includes an isokinetic probe, collection traps, a pump and/or airjet, a sample flowmeter and a vent stack flow monitor. The system continuously withdraws a representative measured sample of stack gas which is passed through traps of activated alumina that is subsequently analyzed by the Analytical Services Laboratory for total uranium, [sup 235]U, [sup 99]Tc and reactive fluoride. Systems for continuous sampling must meet a number of criteria and specifications to ensure quality measurements, high reliability and emergency capability for the functional role of accurately quantifying emissions. A discussion of principles of measurement and critical elements that bear on these criteria is contained in this report.
