I think people get distracted by small, modular nukes we do have on spacecraft and the ones used in the navy for aircraft carriers and subs. Those specialized applications get to ignore issues that are very important to terrestrial civilian application. For example certain kinds of maintenance is handled more frequently than is economically viable in non-military environments, while other kinds of maintenance (& refueling perhaps?) are not required as the entire device is disposed of at the end of life. Also they are surrounded at all times by extremely armed guards :-). This is the same kind of overfitting you see from tech enthusiasts who, say, look at a CPU with a high clock speed and assume X and Y, not realizing all the other aspects that go into the design of a full system. Or wild zomg claims about so-called AI.
