Report: Scale up of SMR would quash financing for renewable energy

A new report by nuclear financing expert Dr. Mark Cooper says $90 billion U.S. investment needed to scale up small modular reactors would likely choke off funding for renewable energy; technology would arrive too late to avert climate change woes

Hopes that small modular reactors (SMRs) will save the dying nuclear power industry in the United States and avert climate change are unfounded. What is far more likely to happen if the U.S. scales up SMRs is that they will choke off the funding and policies that have allowed renewable energy to expand at record levels, while SMRs will suffer all of the same woes that have plagued large nuclear reactors, according to a new report issued today by nuclear financing expert Dr. Mark Cooper.

In his paper, "The Economic Failure of Nuclear Power and the Development of a Low-Carbon Electricity Future: Why Small Modular Reactors Are Part of the Problem, Not the Solution," Dr. Cooper notes:

Scaling up of SMRs would soak up financing for wind and solar power: "While each individual reactor would be smaller, the idea of creating an assembly line for SMR technology would require a massive financial commitment. If two designs and assembly lines are funded to ensure competition, by 2020 an optimistic cost scenario suggests a cost of more than $72 billion; a more realistic level would be over $90 billion. This massive commitment reinforces the traditional concern that nuclear power will crowd out the alternatives. Compared to U.S. Energy Information Administration (EIA) estimates of U.S. spending on generation over the same period, these huge sums are equal to: three-quarters of the total projected investment in electricity generation; and substantially more than the total projected investment in renewables."
Costs of SMRs will be higher than large reactors, not lower: "Even industry executives and regulators believe the SMR technology will have costs that are substantially higher than the failed "nuclear renaissance" technology on a per unit of output. The higher costs result from: lost economies of scale in containment structures, dedicated systems for control, management and emergency response, and the cost of licensing and security; operating costs between one-fifth and one-quarter higher; and decommissioning costs between two and three times as high."
Focusing on SMRs would heighten the growing war between nuclear power and renewables: "The physical and institutional infrastructure to support an active 21st century electricity system is markedly different from and antithetical to the passive, one-way grid on which nuclear relies. In response, even though nuclear technologies have received 10 times as much subsidy on a life cycle basis, nuclear advocates attack the much smaller and more productive subsidies received by renewables. To save nuclear power they propose to jerry-rig markets with above-market prices to increase nuclear profits and remove the regulatory institutions that have allowed alternatives to enter the electricity resource mix."
The private marketplace is already rejecting SMRs: "Two of the leading U.S. developers have announced they are throttling back on the development of SMR technology because they cannot find customers (Westinghouse) or major investors (Babcock and Wilcox). The harsh judgment of the marketplace on SMR technology is well-founded."

Dr. Cooper said: "Large reactors have never been economically competitive and there is no reason to be believe that smaller reactors will fare any better. Giving nuclear power a central role in climate change policy would not only drain away resources from the more promising alternatives, it would undermine the effort to create the physical and institutional infrastructure needed to support the emerging electricity systems based on renewables, distributed generation and intensive system and demand management. My paper shows that nuclear power – whether the reactor is large of small -- is among the least attractive climate change policy options (too costly, too slow, and too uncertain) and is likely to remain so for the foreseeable future."


According to Dr. Cooper, cost escalation provides half of the explanation for the economic failure of nuclear power. The other half is provided by the superior economics of alternatives. In the 1980s nuclear could not compete with coal and natural gas. Today it cannot compete with gas and a number of renewable resources.

The paper highlights the following key points:

Declining cost of alternatives: "Wind and solar technologies are exhibiting dramatic declines in costs driven by innovation and economies of scale that have eluded nuclear for half a century. Improvements in design and operation efficiency, declining material and construction costs, and developments in storage technology have doubled renewable load factors in recent years. The trend is so strong that financial analysts have concluded that these renewable technologies are already cost competitive with natural gas, or soon will be, which makes them much less costly than current or projected nuclear reactors."
Downward pressure on peak prices: "The increasing reliance on renewables and demand response reduces the sharp rise in peak load prices that have traditionally provided the scarcity rents that fund capital intensive facilities. The downward pressures will increase as reliance on decentralized resources increases."
The emergence of an integrated, two-way electricity system based on decentralized alternatives reduces the value and importance of baseload generation: "The emerging electricity system relies on a dramatic increase in information, computational, and control technologies to intensively manage two-way flows in a system that integrates decentralized, diversified supply-side resources and actively manages demand. It causes a sharp reduction in demand and need for central station, baseload generation."
