We would argue that it is a viable option precisely because these risks are well-known and carefully considered. You are not in the early era where little had been established and careful techniques and safeguards were only in a primitive state and not truly put to the test. Much has happened since then to bring an understanding of what is required to deal with nuclear materials to guarantee safety, except for the extreme unlikely circumstance of a natural disaster striking at the right spot, in just the right way, to magically bring together materials in a way that increases the danger, but such scenarios are an extremely low likelihood.
Any concentration of matter containing high potential energy is likely to have some risk associated, and this is a case where there is a huge layer of fear that is actively encouraged and ramped up through mind control manipulation to have people innately fear all things nuclear, known as “radioactive,” and so on, because there are useful technologies that benefit humanity and the interlopers enjoy trying to undermine human progress whenever they see an opportunity. What needs to be guarded against are errors, deliberate misrepresentations of risk, or even a frank denial of the need for strict safety policies, or a lax oversight where sloppy techniques are allowed to happen that put workers at risk, and potentially neighbors in the civilian population in the area of a nuclear facility. The fact this can be engineered to take place via the Extraterrestrial Alliance is simply a risk you have to take in some circumstances, and this is one of those arenas where there is a need for massive energy to supply human needs.
However it is produced, there will be a concentration of highly expensive technology, and often things ongoing in a dynamic way that could result in a tragic explosion or breach of containment causing loss of lives. Even in the early era of steam production, as a major available power source with little else, there were explosions and workmen being scalded to death from burst pipes, and so on. Some of these things just need to be lived with, but if they are kept in perspective with an understanding of what it takes to operate the technology safely, the benefits far outweigh the potential losses, even considering occasional human error—that is what backup systems and redundancy of safety measures have been developed to anticipate and forestall in terms of dire consequences.
Keep in mind, every historical development of technology has had these start-up jitters, and worse, sometimes because of the state of ignorance, but still were recognizing real risks and justifiable fear. For example, at one point, there was a belief that driving an automobile greater than 30 miles per hour would be deadly; the same with aircraft, that flying faster than the speed of sound would cause a disintegration of the airplane, and so on; if people simply gave up and never tested those constraints, the world would be without many modern conveniences currently enjoyed widely and of great benefit.
