Pure sodium reacts rather violently with water. It might make sense to remove that hazard by allowing the violent reaction to take place where and when you want it to happen. It would be similar to neutralizing a bomb by blowing it up under controlled conditions. Video of kids throwing sodium in water: https://youtu.be/NTFBXJ3Zd_4 https://youtu.be/NTFBXJ3Zd_4 edit: in this case the sodium was radioactive though, so blowing it up seems... not good.
