Smaller reactors have many advantages, but in order to be cost effective in competitive energy markets a typical small modular reactor (SMR) will need to operate with a much smaller workforce than today’s large commercial nuclear energy facilities.  This will mandate a retooling of existing nuclear training programs to align with the knowledge and skills needed by the SMR staff.
As opposed to fossil-fueled power plants in which the majority of operating costs are associated with the fuel they burn, the majority of the costs of generating electricity from nuclear energy are associated with the costs of capital to build the plant, and the ongoing cost of people needed to operate and maintain (O&M) the plant.  The capital costs, determined by construction & financing costs, are generally fixed during the first decades of operation.  The O&M costs, however, vary over the life of the plant and are highly dependent on overall labor costs; the number of people required and their salaries and benefits, contracted labor costs, and the cost of out-sourced services. For this reason the long-term economic viability of nuclear energy facilities relies upon maintaining capacity factors high and labor costs reasonable and predictable.  Obviously, the balance sheet also depends on the structure of the energy market in which the facility is located.
Anti-nuclear groups understand this connection between labor costs and economic viability.  For years their strategy has been to convince nuclear regulators of the need for ever-tougher standards resulting in larger and larger staff sizes and thus tighter profit margins.  They are, in a very deliberate way, working to regulate nuclear energy out of business.  Coupled with lower electricity market prices brought about by falling natural gas prices, these higher labor costs mean some smaller nuclear plants are finding it increasingly difficult to maintain profitability.
