Tellurium Behavior in Containment Under Light Water Reactor Accident Conditions.

摘要

Interactions of tellurium in containment can result in changes of physical form and therefore in its transport properties. The report discusses the most probable forms of tellurium in a containment environment under LWR accident conditions. The physical and chemical form of inorganic tellurium species will be determined by condensation, oxidation, and dissolution in water. Of the three volatile tellurium chemical forms, Te2(gas), H2Te, and organic tellurides, only organic tellurides have the potential to remain in the gas phase in a containment atmosphere. There is a general lack of information on the formation and removal of organic telurides under LWR accident conditions.
