ている。In other words, the air-cooled spent nuclear fuel or fission products that have been announced so far? As shown in Figures 1 to 582, storage of the vitrified RU solidified material can be done by using the draft effect of the exhaust stack, or by using a strong intake of outside air with a fan ICJ. Since the calorific value from the radioactive material has been removed, it is released from the a-air system to the outside air system.

た。However, with the method described above, even a small amount of radiation 1f7.
If there is a leak, radioactive materials will be released into the environment, and the radioactivity leak will increase.4. The fact that a large amount of air continues to be exhausted every day from the radioactive material storage facility is a cause for concern for local residents #C, and taking into consideration the worst case scenario, it is necessary to carry out appropriate cleaning measures. There were some drawbacks.
