Thermochemical data acquisition
Thermochemical data are required for specific fission product and reactor materials compounds in order to quantify the consequences of a severe accident within a light water reactor. Approximately 40 important compounds/systems have been identified for study for which thermodynamic data did not exist or were inadequate. Work is described on the analysis of approximately half of these systems, using various calorimetry techniques, vapour transport, gas-phase infrared spectroscopy, quadrupole mass spectrometry and matrix isolation infrared spectrometry, over the temperature range from 298 to 3000 K. The adoption of these data within appropriate modelling codes will allow the fission product species and transport to be predicted with greater confidence, thus providing more accurate assessments of the consequences of severe reactor accidents.
