The problem with something like this is just exactly the same as a flying car: It introduces more problems than it solves.

For example, the flying car: Neat idea, but what happens when an amateur aviator encounters fog? And what happens if he encounters fog with one of his instruments broken? And what makes you think that he's going to know how to use those instruments anyway? As it is right now, ground-based vehicles are usually operated by people with little training, terrible vehicle control skills, little "captaincy", and they are usually either drunk or on their cellphone or both.

Same situation is true with a micro nuclear reactor. This device needs to be carefully operated and maintained if it is to remain safe. It isn't dangerous- it is simply very unforgiving of any carelessness or neglect, and the very nature of a device such as this scaled to this size lends itself to these last. When you make something small and easily obtainable, human beings have a tendency to "disregard" it or in simpler terms...not take it seriously. Along this vein, the average American tends to view their car and their microwave in the same way. It's operation isn't important- just do it and go about your business, per se. This poor attitude would certainly lead to a terrible nuclear accident eventually, and the result would be a large section of territory uninhabitable for upwards of 200,000 years.

Hmm...
