These costs include typical reactor repair +and refueling, the labor involved to complete such +maintenance, and finally the labor involved in operating the +reactor itself. Currently the largest of these O&M expenses +is the labor and part cost used in maintenance, while large +nuclear reactor facilities require a modest reactor operator +budget per megawatt of energy produced. The advent of small +modular reactors (SMRs) and microreactors (MRs) will change +these economics significantly. + +As SMRs and MRs become more common, the cost of repair and +maintenance should reduce dramatically as nuclear power +componnets will become modular, replaceable parts instead of +the bespoke reactor designs currently operating. Operator +wages, however, can be expected to increase without +introducing greater controller autonomy. SMRs and MRs are +much smaller output designs per reactor core, and if they +are required to employ the same size reactor operator team +as a conventional large reactor, will suffer from much +larger operator expense per megawatt. Greater controller +autonomy can solve this problem by unloading some reactor +control responsibilities from the operator, and therein +reduce labor consumption. + +<# TO DO #> +Finally reactor safety can be improved by greater autonomy +yada yada find some reasons to back this up. ### Related Papers:
