I think we are discussing 2 different things here.
For a dedicated energy storage device, quenches are a serious issue. In the 70s, they planned devices with several 100m diameter, for storage of some 10 TWh, so a quench could release the energy of a small atomic bomb.
For superconductors that are not meant for energy storage but to produce a magnetic field, i have to agree Josef, this is not an unsolvable problem (although i disagree that the energy is evenly heating the whole magnet. Instead of 17 degrees increase for the whole structure, it could be 1700 degrees for 1% of it). They can be built to release the energy safely. The quench-videos on youtube actually demonstrate this, they are doing as they were designed to. The magnets for a fusion reactor could be pumped separately, evaporation of helium and a overpressure ventile might already be sufficient. There will be repairs, it may cost a bit to have the reactor offline for a few days, but there will certainly not be a real hazard for people.
The comparison with fukushima is unfair, because that plant was designed for a tsunami of a certain height, and then a higher tsunami occured. In case of a magnet, in contrast, we know exactly how much energy it contains and can design it accordingly.

Because we can.
