An energy proposal in Illinois that would keep the state’s nuclear power plants on line while providing incentives for wind and solar generation is likely to be approved by Illinois lawmakers and signed into law by the governor, according to a news report yesterday from Capitol News Illinois.

Senate president Don Harmon (D., Oak Park) noted on June 1 that a deal had been reached between Gov. J. B. Pritzker and Exelon, the parent company of Commonwealth Edison and the owner of six nuclear power plants in Illinois.

Job saver: Approving the energy deal “would save jobs, which has been our goal all along,” Harmon said. “That’s why we support the governor in these talks. We also stand with the governor on decarbonization targets that need to be in a final deal.”

As governments around the world cooperate on the ITER tokamak and, in parallel, race each other and private companies to develop commercial fusion power concepts, it seems that “game-changing” developments are proclaimed almost weekly. Recently, the United Kingdom and China announced new fusion program results.

U.S. energy secretary Jennifer Granholm and French minister for the ecological transition Barbara Pompili issued a joint statement on May 28 in which they pledged to work together to meet shared climate goals.

“France and the United States share common goals and common resolve in fighting climate change and working toward reaching the ambitious target set forth by the Paris agreement,” the statement read. “We are united in a common ambition on both sides of the Atlantic: achieving net-zero carbon emissions by 2050. Reaching this common objective will require leveraging all currently existing emission-free technologies available to us while simultaneously intensifying research, development, and deployment across a suite of zero-emissions energy sources and systems. Ensuring that these energy systems are efficient and reliable, integrating larger shares of renewables coupled with nuclear energy, which is a significant part of today’s electricity production in both our countries, will be crucial to accelerate energy transitions. Reaching this common objective will also require a wide variety of favorable financing conditions across the range of zero-emitting power sources and systems.”

For more than 50 years, the ANS Honors and Awards Program has recognized outstanding achievements and meritorious service in the various fields served by our Society.

The recipients of the national awards listed below will be honored on November 30 during the opening plenary of the ANS Winter Meeting. Honorees will be notified of their selection by October.

All members are encouraged to review the nomination requirements for these awards and consider nominating a qualified colleague. Many ANS awards are open to non-ANS members, and nominating colleagues who are not members is one way to foster new ANS relationships.

The transfer of the Indian Point nuclear power plant from Entergy to Holtec International and its subsidiaries was completed last week. Under the asset transfer deal, Holtec Indian Point becomes owner of the closed plant, with Holtec Decommissioning International serving as the site’s license holder and decommissioning operator.

The Department of Energy is providing up to $2 million in fiscal year 2022 to fund university and national laboratory studies into the use of novel, medically relevant isotopes for use in pre-clinical and clinical medical trials, the DOE’s Office of Science announced on June 1.

The Department of Energy’s Office of Environmental Management will award the Idaho Cleanup Project contract for the Idaho National Laboratory site to Idaho Environmental Coalition (IEC), of Tullahoma, Tenn. The contract has an estimated ceiling of approximately $6.4 billion over 10 years, with cost reimbursement and fixed-price task orders to define the contract performance.

Unit 2 at Pakistan’s Karachi nuclear power plant officially began commercial operation in late May, gaining the distinction of being the first Hualong One reactor outside of China to do so, China National Nuclear Corporation announced last week. Construction of Karachi-2 began in August 2015, and connection to the grid was accomplished in March of this year.

The World Nuclear Association has issued a white paper advising the world’s policymakers and regulators to adopt a science-based, all-hazards risk assessment and management system that holistically evaluates the contributions of different energy sources and sets a level playing field.

The paper, Recalibrating Risk: Putting Nuclear Risk in Context and Perspective, states that disproportionately focusing on the risks posed by radiation can result in the acceptance of other, more significant risks. For example, the WNA says, while air pollution from heavy fossil fuel use worldwide has caused the early demise of millions, severely damaged the environment, and exacerbated climate change, nuclear power is routinely ostracized and its substantial contributions to global decarbonization disregarded.

Three United Kingdom organizations—the Nuclear Industry Association, RenewableUK (formerly the British Wind Energy Association), and Solar Energy UK—are calling for urgent action to build new nuclear, wind, and solar capacity and for a binding target of 100 percent grid decarbonization by 2035.

The United Kingdom was the first of the world’s major economies to embrace a legal obligation to achieve net-zero carbon emissions by 2050.

Capacity factor is a measure of reliability, and reliability delivers results. The U.S. nuclear power fleet produced about 789.9 TWh of clean electricity in 2020 and ended the year with 94 operating reactors. According to Energy Information Administration data, that’s about 37 percent more electricity than the 576.9 TWh produced in 1990 by a much larger fleet of 112 reactors.

Nuclear News has tracked and analyzed the capacity factors of the U.S. fleet since the early 1980s, before concerted industry efforts yielded unforeseen performance improvements. High nuclear capacity factors are now less an achievement than an expectation. So much so, in fact, that advanced reactors in development today are assumed to be capable of achieving capacity factors above 90 or even 95 percent.

The U.S. fleet has maintained a median capacity factor near 90 percent for 20 years (see Fig. 1), and the median design electrical rating (DER) net capacity factor for 2018–2020, at 91.33, does not disappoint—unless by showing virtually no change relative to the median of 91.34 recorded in 2015–2017. However, this lack of meaningful difference only underscores the consistent reliability of the U.S. fleet.

Operators at the Advanced Test Reactor at Idaho National Laboratory have begun a nine-month outage to perform a core internals changeout. When the ATR is restarted in early 2022, the top head closure plate of the pressurized water test reactor will have new access points that could permit the irradiation of more fuel and material samples in the reactor’s high-flux neutron conditions.

The Canadian Nuclear Safety Commission (CNSC) has completed phase one of its pre-licensing vendor design review (VDR) for Moltex Energy’s 300-MW Stable Salt Reactor–Wasteburner (SSR-W)—a molten salt reactor that uses nuclear waste as fuel. CNSC entered into an agreement with Moltex in November 2017 to conduct the initial phase of the review.

Historically, we have used the May issue of Nuclear News to analyze capacity factor data for U.S. nuclear plants. Once again, the topline story is the continuation of a 20-year period of outstanding operational performance. In 2020, the U.S. nuclear fleet generated about 789.9 TWh of electricity, surpassing coal to become the second-largest source of electricity in the nation. Overall, the fleet recorded a median three-year capacity factor of 91.33, besting the three-year median of 91.20 published just last year. With some of our most venerable plants among the top performers, it’s no wonder that several utilities are investing now to ensure their plants can generate clean energy into their eighth decade or beyond.

After declaring its intention earlier this year to invest in nuclear technologies in Poland, Westinghouse Electric Company on May 24 announced the establishment of a “world-class” global shared service center in Kraków.

Do you have TRU waste with characteristics and/or prohibited items not acceptable in their current configuration for transportation and/or disposal at WIPP? Such as liquids, oxidizers, corrosives, reactive materials, flammable liquids, and aerosol cans? Are you sorting and segregating the non-compliant waste forms and then developing process/treatment approaches (i.e., solidification, grouting, deactivation, etc.) to ensure your final waste form will meet transportation and WIPP’s acceptance requirements?

The only constant, as the saying goes, is change. Since adopting the American Nuclear Society Change Plan 2020 at the ANS Winter Meeting in 2019, the Society has been in a state of seemingly constant change. Many important improvements have been implemented under the Change Plan—including to this magazine and our news site, ans.org/news—with an eye toward making ANS a more modern and adaptable organization. Some changes also have better enabled ANS to quickly respond to events that were out of our control and forced us to take on new endeavors (thanks, COVID‑19)—a prime example being the 2020 ANS Virtual Annual Meeting and subsequent virtual meetings that followed.

Portland, Ore.–based NuScale Power has announced the signing of a memorandum of understanding with the Grant County Public Utility District (Grant PUD) to evaluate the deployment of NuScale’s advanced nuclear technology in central Washington state.

The Advanced Test Reactor (ATR) at Idaho National Laboratory is getting an overhaul that will keep it off line for nine months. When the ATR is restarted in early 2022, the one-of-a-kind pressurized water test reactor—which is operated at low pressures and temperatures as a neutron source—will be ready for another decade or more of service, with the potential for more experimental capacity in years to come.

The UK SMR consortium last week revealed the latest design and power upgrade—from 440 MW to 470 MW—for its proposed small modular reactor. According to the consortium’s lead company, Rolls-Royce, the “refreshed” design features a faceted roof, an earth embankment surrounding the reactor to integrate with the landscape, and a more compact building footprint.
