In a May 15 piece, the editorial board of The Denver Gazette has weighed in on Colorado’s continuing controversy regarding how the state gets its electricity. While the current discourse in the state primarily pits fossil fuels against wind and solar, the board asks, “How about an energy source that generates almost limitless power, leaves no carbon footprint, and produces practically no emissions? It’s nuclear power—as green as you can get.”

What are the key cost drivers for microreactors?

May 17, 2022, 9:30AMNuclear News

Microreactors upend the traditional economics of nuclear power plants by shifting the paradigm from economies of scale (large reactors) to economies of multiple (mass production). While shrinking power output per unit may increase costs per kilowatt compared to large plants, offsetting gains can be expected from simplified and standardized designs, factory fabrication, inherent safety, lower radionuclide inventories, fast installation, and low financing costs. For instance, the lower power density in a microreactor core leads to a greatly reduced decay heat source, simplifying emergency cooling needs. These design aspects can lead to innovations including substantial simplifications to safety and control needs, minimized human operational requirements, a very compact balance of plant, the ability to fabricate almost every component in a factory, shortened construction time, and less daunting financing.

Bloomberg Law describes nuclear's efforts to attract ESG-based investment

May 17, 2022, 7:01AMANS Nuclear Cafe

The nuclear industry and its supporters want to ensure that current and future reactors are weighed by climate-conscious investors as a net benefit, according to a recent story, Nuclear Power’s Climate Credentials, Footprint Spark ESG Debate, by reporter Daniel Moore in Bloomberg Law. The interest comes as investors are increasingly sensitive to environmental, social, and governance (ESG) issues. Nuclear’s benefits must be included “in the array of ESG frameworks sprouting up to define the scope of any energy project’s climate impact,” writes Moore.

U.S. nuclear capacity factors: A smaller fleet invested in the future

May 13, 2022, 2:59PMNuclear NewsSusan Gallier

The United States has just 93 operating power reactors at this writing. The fleet last numbered 93 in 1985, when nuclear generation topped out at 383.69 TWh, less than half of the 778.2 TWh produced in 2021.

While the 93 reactors operating today have more capacity, on average, than in 1985, most of that increased productivity is down to operational improvements that pushed the fleet’s average capacity factor from just 57.5 percent in the three-year period 1984–1986 to near 90 percent by the early 2000s.

An independent review of Denmark’s radioactive waste management program by an International Atomic Energy Agency team found that the country has developed a robust and well-functioning system, but that the national program needs further refinement if it is to be effectively implemented.

The government of Denmark requested the review of its waste management program to fulfil its European Union obligations requiring an independent review of EU member states’ national radioactive waste management programs. The Danish parliament adopted a resolution outlining the policy goals and activities of its national program for safely managing radioactive waste and spent nuclear fuel in 2018.

U.K. nuclear services company Cavendish Nuclear has signed a memorandum of understanding with U.S. reactor and fuel-design engineering firm X-energy to act as its deployment partner for high-temperature, gas-cooled reactors (HTGRs) in the United Kingdom.

Headquartered in Rockville, Md., X-energy is the developer of the Xe-100, an 80-MWe reactor with a modular design permitting it to be scaled into a “four-pack” 320-MWe power plant. As a pebble bed HTGR, the Xe-100 would use TRISO particles encased in graphite pebbles as the fuel and helium as the coolant.

According to a May 11 joint statement from the companies, development and deployment of HTGRs in the United Kingdom would support an increase in the nation’s energy security, contribute toward the government’s net-zero-by-2050 commitment, and create considerable opportunities for the U.K. nuclear supply chain.

The new equipment has been installed in Argonne’s Mechanisms Engineering Test Loop (METL), and its first experiments are supporting data validation needs of Oklo, Inc., by simulating normal operating conditions as well as protected and unprotected loss-of-flow accidents in a sodium-cooled fast reactor.

Focusing on nuclear plant life-cycle O&M from the beginning

May 12, 2022, 3:12PMNuclear NewsChuck Goodnight

Nuclear plant designers focus on safety and efficiency, and rightly so. But the next steps for new nuclear power technologies and new-build programs are typically focused on “overnight costs,” or the costs to develop the site and construct the nuclear power plant. The problem is that the overnight costs are only the “table stakes” in a much longer game. Investors and stakeholders must have the staying power to play until the end, which now looks to be close to 100 years after the start of a new-build program.

Assuming that the initial estimates of overnight costs are surmountable, total life-cycle costs (TLCs) should be next on the agenda, as they will significantly drive the final levelized cost of energy. TLCs include overnight costs, the operating company’s startup and development (or expansion) costs, life-cycle O&M costs, life-cycle capital reinvestment, shutdown/SAFSTOR, decommissioning and dismantling, and site remediation. The largest element of TLCs will be the non-fuel portion of life-cycle O&M costs, and the largest portion of those costs will be for labor.

“Being real means that the renewable revolution requires nuclear power”: Bulletin of the Atomic Scientists op-ed

May 11, 2022, 3:14PMANS Nuclear Cafe

Edesess

In a recent opinion piece in the Bulletin of the Atomic Scientists, mathematician and economist Michael Edesess writes that “The goal of net zero greenhouse gas emissions by 2050 [appears] unrealistic.” Edesess, a research associate of the EDHEC-Risk Institute, adds, “We must, in the final analysis, be realistic. Being real means that the renewable revolution requires nuclear power.”

Then: Edesess traces the history of interest in renewable energy sources to the 1970s when, he notes, climate change was not even part of the calculations. Back then, the thought was, “We only needed to reduce the oil we imported from the Middle East. Solar and wind could do that if only we could drive the cost down.” However, “For nuclear, driving the cost down was not the objective. The objective was to make nuclear power ever safer and safer. This drove nuclear power’s cost up.”
