Index > Considerations - 3. Seismic safety｜Example of method 3 "Retrieving fuel debris from the side”
ⅱ) Considerations - 3. Seismic safety
Issues to be noted for the proposing method in terms of safety are explained below.
- Consideration shall be made for seismic safety and spesific study shall be performed in C/S
Issues requiring special attention 3. Seismic safety
(1) Prior preparation
- Seismic assessment when creating opening on the building for investigation and fuel debris retrieval
(2) Install barrier
- Seismic assessment of barrier equipment
- Seismic capacity of building when installing barrier on the first floor
(3) Create opening on the side of PCV
(4) Install equipment and access
- Seismic safety of equipment for fuel debris retrieval
- Seismicity of the building where the equipment for retrieval is located on the first floor
(including shielding facilities)
(5) Dismantle and remove internal structures
- Seismic assessment of equipment for retrieving fuel debris
- Structural stability of internal structures during dismantling of internal structures
(6) Retrieve fuel debris
(7) Transport canister
(8) Clean-up equipment
