Small, modular reactors-which typically produce less than 300 megawatts of electricity-have been a rising trend within the industry during the past year, with several companies proposing new SMR designs and beginning interactions with the Nuclear Regulatory Commission.Rebecca Cooper...
The cost of a nuclear power plant (NPP) is an important influence on the future commercial success of Small Modular Reactors (SMRs). At the early design stage, the cost requirements of SMRs can be derived from an analysis of the factors driving the Levelized Cost of Electricity (LCOE). ...
By developing engineering cost models of nuclear reactors and plants, studies have provided cost benchmarks for plant construction in the US56,57,58,59,60,61,62,63and other countries (e.g., Harris et al.64). Other, forward-looking studies have outlined strategies for cost reduction, such ...
While the company has been considering small modular reactors (SMRs), submitting an early site permit to the Nuclear Regulatory Commission in January 2017 for thepotential construction and operation of multiple SMRs at the Clinch River site in Oak Ridge, Tennessee, they likely won’t be realized...
Small Modular ReactorsSMRLight Water ReactorsSmall modular reactors (SMRs) offer simple, standardized, and safe modular designs for new nuclear reactor construction. They are factory built, requiring smaller initial capital investment and facilitating shorter construction times. SMRs also promise ...
The results are compared between one another and with current generation large reactor designs providing a rough comparison of the long-term economics of a new nuclear reactor project. SMRs are predicted to have higher fuel costs than large reactors. Particularly, integral pressurized water reactors ...
Under this assumption, the labor associated with the fabrication of composite modules is reduced, as they are integrated in the new modules design. This construction methodology was applied to the WEC-SMR. Activities in the on-site assembly stage were moved to the off-site fabrication stage ...

Overall, if built by an inexperience vendor and work force, the two SMRs' overnight cost were higher than large reactors since significant on-site labor still remains while losing economy of scale. However, the single-unit SMR had significantly less total person-hours of onsite labor, and if...
