“…The IRIS vessel has an internal diameter of 6.2 m and an overall height of 22.2 m, which makes it approximately 50% larger than the RPV of the AP1000. Nevertheless, the size of the IRIS containment is a fraction of the size of corresponding loop reactors, resulting in a significant reduction in the overall size of the plant [86].…”

“…Obviously if "economies of scale" is the unique driver for the cost estimation SMR are not competitive respect to LR. However many recent references [6][7][8] point out as this is true as long as the comparison considers the specific cost [$/kWe] of 1 LR respect 1 SMR. On the other hand, when the comparison is carried out considering the same power installed in the site (1340 MWe equivalent to 1 LR or 4 SMR) the result changes.…”

Several improvements have been made in the nuclear energy sector during the last decade leading to new design for advanced nuclear power plants. Literature presents several studies about the economics of these new Power Plants, however the economic analysis of these plants usually considers only the classical accounts related to Construction, Operation & Maintenance, Fuel and Decommissioning. Beside these accounts there are many factors, from now on named External Factors (e.g. social acceptability, enhanced safety, emergency planning zone reduction, etc.) able to heavily determine the profitability of the investment. This paper presents the differential impact of these External Factors on nuclear technology with different sizes. According to the classification currently in use in the IAEA, small reactors are those with electric generation power lower than 300 MW, while medium sized reactors are those with electric power between 300 and 700 MW [1]. We define “Small Medium Reactors” (SMR) reactors with an electrical output smaller than 700 MW (usually 335 MWe) and as “Large reactors”, (LR) reactors with an equivalent electric power greater than 700 MW. (usually 1340 MWe) Starting from the international literature point of view, the paper provides a list of external factors distinguished in economically quantifiable or not. Two different approaches have been used for their assessment: a monetary ranking and a strategic one. Then, using a Quality Function Deployment approach, a multi-attribute model is introduced to obtain a weight for every external factor, dividing their impacts into three sustainability dimensions (economic, environmental and social). The results show that the new SMR perform better than LR thanks to the smaller size which allows an enhancement of the safety level (which affects the public opinion) and a greater flexibility in the market.

a b s t r a c tLoad following is the potential for a power plant to adjust its power output as demand and price for electricity fluctuates throughout the day. In nuclear power plants, this is done by inserting control rods into the reactor pressure vessel. This operation is very inefficient as nuclear power generation is composed almost entirely of fixed and sunk costs; therefore, lowering the power output doesn't significantly reduce generating costs and the plant is thermo-mechanical stressed. A more efficient solution is to maintain the primary circuit at full power and to use the excess power for cogeneration. This paper assesses the technical-economic feasibility of this approach when applied to Small Modular Reactors (SMR) with two cogeneration technologies: algae-biofuel and desalinisation. Multiple SMR are of particular interest due to the fractional nature of their power output. The result shows that the power required by an algae-biofuel plant is not sufficient to justify the load following approach, whereas it is in the case of desalination. The successive economic analysis, based on the real options approach, demonstrates the economic viability of the desalination in several scenarios. In conclusion, the coupling of SMR with a desalination plant is a realistic solution to perform efficient load following.
