Ionic thermometers have been tested in a nuclear reactor with attention to the steepness of the ionic conductivity jump and the influence of a glass container on the accuracy of the temperature measurements. It was found that, at the neutron fluxes up to 1.5×1018 m−2 s−1 (thermal) and 3×1018 m−2 s−1 (fast) in a light water reactor, the change of conductivity jump slope is negligible or nil for an ionic thermometer filled by HgI2, i.e., at 256.0±0.2 °C. The need to use boron-free glass was confirmed. The impact on the accuracy of the temperature point indication in a nuclear reactor core is discussed, as well as obvious inertness of the melting process mechanism to the intense irradiation field.
Die Verbindungen CaUO4, CaU2O7, Ca3UO6 und Ca2UO5 wurden hergestellt und röntgenographisch identifiziert. Die IR‐Spektren dieser Verbindungen wurden gemessen. Aus UO2 mit 5% Gew. CaO, das 7 Monate lang einer oxydierenden Atmosphäre ausgesetzt worden war, waren keine nachweisbaren Mengen von Uranat(VI) entstanden.
Die geschlossene galvanische Hochtemperatur‐Zellenanordnung wird durch Untersuchung der sich im Gleichgewicht befindlichen Proben stark unterstöchiometrisch zusammemgesetzter Mg‐, Ca‐, Sr‐ und Ba‐monouranate getestet.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
