The drying process of a type of high burn-up spent fuel dry storage container for domestic third generation nuclear power units was analyzed theoretically and studied experimentally. Results show that
it is suitable to use the adsorption drying process for treatment
and the drying process needs to last at least 4.1 h
which can meet the drying standard that the water vapor content in the container is lower than 400 Pa as required in the equipment specification book. The drying process is divided into two stages. In the first stage
there is a large amount of liquid residual water in the container
and the humidity is relatively stable. In the second stage
there is only water vapor
and the humidity drops rapidly. More than 5/6 of the moisture in the container is discharged through the cooler in test bench
and the remaining is absorbed by the dryer.
