FACILITY FOR STORING RADIOACTIVE SUBSTANCE

摘要

PROBLEM TO BE SOLVED: To compact a facility for storing radioactive substances which is suitable to store spent fuel assemblies and vitrified high-level radioactive waste. SOLUTION: The facility 1 for storing spent nuclear fuel has fuel storage areas 5 for storing fuel casks 2 in a storage building 30. The fuel storage areas 5 are located on both sides of a central wall 13 of the building 30 and have fuel storage rooms 11 partitioned with bulkheads 21. An exhaust passage 12 is placed on the side of the building central wall 13 in each of the fuel storage rooms 11, and an air supply passage 31 is placed on the side of a building outer wall 17 of each of the fuel storage rooms 11. Each of the fuel storage rooms 11 communicates with the exhaust passage 12 through an opening 19 and the fuel storage rooms 11 and the air supply passage 12 communicate with an opening 20. A passage 18 for carrying in and out the casks 2 is formed by allowing each of the air supply passages 31 to communicate through an opening 22a (or 22b). The fuel casks 2 are carried into the fuel storage rooms 11 by way of passages 15 and 18 for carrying in and out the casks 2. Since the exhaust passage 12 and the air supply passage 31 are also used as the passage 18 for carrying in and out the casks 2, the facility 1 for storing the spent fuel can be compacted.
