Design, Construction, and Testing of a 2000 Deg C Furnace and Fission Product Collection System.

摘要

An induction furnace, capable of operation at 2000 degrees C in steam, was developed to conduct product release tests. The apparatus for collecting the released fission products includes a TGT, an aerosol deposition sampler, a series of glass fiber filters, and heated charcoal. A steam condenser and cooled charcoal, for inert gas adsorption, are located further downstream. The principal analytical techniques used for fission product identification and measurement are (1) gamma spectrometry, for all radionuclides on all test components; (2) spark-source mass spectrometry, for all elements, primarily deposits on the thermal gradient tube and filters; and (3) neutron activation, for iodine on selected test components.
