That's not "speaking hypothetically", it is illogical , unless you changed you mind and are no longer certain.
As you can't see the obvious difference in danger levels between a nuclear fission plant and an SK LENR reactor, there is no point in continuing this discussion.
You couldn't come up with a single example of how the SK presents a potential danger.
Adrian: please pay attention.
Safety is not about knowing a specific issue will happen. It is about being sure no issue will happen.
For Rossi to sell heat his kit will need safety validation as a boiler. you are surely aware of the many ways steam can be dangerous. Since the heat source is unconventional that will, unless Rossi lies, create issues. How can he prove there is no possibility of runaway excess heating?
In addition, if claims are believed, this is a NUCLEAR reactor. The first unconventional one ever one delivering (what did you suggest?) GW of power. Certification for anything nuclear is extraordinarily difficult, even proven designs.
Since no-one currently understands how LENR works there is no way to be sure it is safe. It is clearly manipulating nuclei and Rossi is not exactly good at letting people measure his stuff. Remember, the well-,measured devices have all not been working for one reason or another.
The very high energy density and the fact that high energy particles are toxic in themselves and (neutrons) create difficult to dispose of radionuclides mean that anything nuclear is very carefully inspected for safety (actually more so than I personally think is needed).
I suggested above that the SK/QX/anything from Rossi would fail this.
You seem not to have much imagination over how a novel nuclear device would be dangerous. Under unusual conditions it could generate high energy neutrons which are a big no-no especially when not expected (Rossi does not expect these since no lead shielding). It could create other high energy toxic particles. It could lead to toxic waste.
You perhaps hope that a working LENR device would not do any of these things. But you, and safety authorities, cannot know this. In fcat no-one can know this since working high power LENR devices do not currrently exist, and no theory predicts how they work. Neither experiment nor theory confers safety.
Why has this not been a problem for Rossi so far? Easy. No-one believes he has a working nuclear device. And Rossi states this to authorities when they come round.
Should his devices be seen to work, with energy density obviously beyond anything non-nuclear, that belief would quickly change and the Nuclear safety guys will no longer be dismissable by Rossi saying he has no nuclear devices.
