Table 18 Evaluated items with a trade-off relationship during the attenuation activities
No | Evaluated items with a trade -off relationship | Details | |
|---|---|---|---|
1 | Wind direction | Activities after concentration reduction | If the robot is placed with the wind direction in mind, attenuation near the building entrance becomes difficult because the building entrance is not on the windward side |
2 | Type of water discharge | Distance and position from the command headquarters | If the robot is placed in a position where the command headquarters can see the attenuation activity, it will be far away from the leak area, which is far from the range of the wide-angle water discharge that is considered to be suitable for attenuation |
