Abstract: A system and method for drying cavities loaded with high level waste (“HLW”) is devised. The invention utilizes a non-intrusive procedure that is based on monitoring the dew point temperature of a non-reactive gas that is circulated through the cavity. In one aspect, the invention is a system for drying a cavity loaded with HLW comprising: a canister forming the cavity, the cavity having an inlet and an outlet; and a source of non-reactive gas. The system further flows the non-reactive gas from the source of non-reactive gas through the cavity; and repetitively measures the dew point temperature of the non-reactive gas exiting the cavity.
