Temperature limits based on the saturation temperature in Hanford waste storage tanks

摘要

This report calculates limits on the measured temperature readings to limit the occurrence of saturation temperatures in Hanford waste storage tanks. The results in this report show that the temperature reported by a thermocouple tree in a double-shell tank can be significantly below the maximum waste temperature and that provisions should be made for that offset in any tank temperature monitoring program. The results for single-shell tanks show that some tanks may be at or above the saturation temperature.
