These are quite a few reports for one day for a technology we purportedly have under full control, nothing to worry.
Reports don't mean danger, and they don't mean lack of control. Reports are information.
I'm also not totally against nuclear, in case you are suspecting that. I do think though, that we as a society aren't at the point where we have the ability to completely control such technology, contrary to what proponents of much higher utilization of nuclear like to claim. Reports of fuses seemingly without failover or stolen equipment seem to support that argument.
