Exelon's Byron generating station in northern Illinois. The future of Byron is uncertain at this time and could impact the new power generation company, once it's formed.

Exelon Corporation announced yesterday that it intends to spin off Exelon Generation, its competitive power generation and customer-facing energy businesses, from Exelon Utilities, its group of six regulated electric and gas utilities.

The split into two publicly traded companies will “establish the nation’s largest fully regulated transmission and distribution utility company and the largest carbon-free power producer paired with the leading customer-facing platform for clean, sustainable energy solutions,” Exelon said in its February 24 announcement.

Nuclear power could produce as much as one-third of the United Kingdom’s clean hydrogen needs by 2050, posits the Hydrogen Roadmap, a 12-page report recently approved by the Nuclear Industry Council (NIC) and released last week by the Nuclear Industry Association (NIA).

The NIC, co-chaired by the British government’s minister for business, energy, and clean growth, and the chairman of the NIA, sets strategic priorities for government-industry collaboration to promote nuclear power in the United Kingdom.

The road to net zero: The report outlines how large-scale and small modular reactors could produce both the power and the heat necessary to produce emissions-free, or “green,” hydrogen. Existing large-scale reactors, it says, could produce green hydrogen today at scale through electrolysis, as could the next generation of gigawatt-scale reactors. Also, according to the report, SMRs, the first unit of which could be deployed within the next 10 years, could unlock possibilities for green hydrogen production near industrial clusters.

Amid all the talk of last week’s winter storm and the resultant grid debacle in Texas, Exelon on Monday issued a press release informing customers of just how reliably its Illinois nuclear power plants have been operating this winter.

The release might also be seen as a message to state lawmakers, who have yet to produce any legislation to aid the utility’s financially challenged nuclear facilities—of which two, Byron and Dresden, have been slated for retirement later this year, given the (so-far) absence of such legislation.

The Nuclear Regulatory Commission is seeking public comment on a proposed rule that would amend the licensing, inspection, special projects, and annual fees charged to the agency’s applicants and licensees for fiscal year 2021.

Published in the February 22 Federal Register, the proposed fee rule reflects a total NRC budget authority of $844.4 million, a drop of $11.2 million from FY 2020.

The amendments are mandated by the Nuclear Energy Innovation and Modernization Act (NEIMA), the nuclear industry–backed legislation signed into law by President Trump in January 2019 (NN, Feb. 2019, p. 17). NEIMA requires the NRC to recover approximately 100 percent of its total budget authority in FY 2021, except for specific excluded activities. (Previously, the requirement was approximately 90 percent.) In addition, NEIMA established a new cap for annual fees for operating reactors and included requirements to improve the accuracy of invoice for service fees.

NASA’s Perseverance rover, which successfully landed on Mars on February 18, is powered in part by the first plutonium produced at Department of Energy laboratories in more than 30 years. The radioactive decay of Pu-238 provides heat to radioisotope thermoelectric generators (RTGs) like the one onboard Perseverance and would also be used by the Dynamic Radioisotope Power System, currently under development, which is expected to provide three times the power of RTGs.

Idaho National Laboratory is scaling up the production of Pu-238 to help meet NASA’s production goal of 1.5 kg per year by 2026, the DOE announced on February 17.

There has been no off-site impact from the February 13 earthquake that struck off the east coast of Japan near the Fukushima Daiichi nuclear power plant, Tokyo Electric Power Company (TEPCO) reported on February 19. The earthquake, however, has caused a water leakage from two of the site's primary containment vessels (PCVs).

A nuclear alert order was issued by the plant about 20 minutes after the earthquake, and the water treatment and transfer facilities were shut down. Inspections after the event revealed no anomalies and the nuclear alert order was rescinded on February 14.

The nuclear plant in Fukushima Prefecture in northeastern Japan is now undergoing decommissioning.

A new survey exploring the attitudes of Canadians toward climate change and their expectations and level of support for government intervention to tackle the issue finds that 86 percent believe that Canada should invest in clean technologies, including renewables and nuclear energy.

The survey, conducted by research and strategy firm Abacus Data between January 29 and February 3, was commissioned by the Canadian Nuclear Association (CNA).

CNA says: “It’s clear there is strong support for the government to implement a mix of solutions to address the [climate change] challenge, including investing in renewables and clean nuclear technologies,” stated John Gorman, CNA president and chief executive officer, in a February 18 press release. “We continue to see that the more understanding Canadians have, the more they support zero-emissions nuclear technologies to help reach our net zero 2050 goal. This includes investment in small modular reactors, which Canadians believe bring value to replace carbon-based fuels with clean electricity, decarbonize high-emissions industries, and transition remote communities away from reliance on diesel.”

Bulgaria’s Kozloduy nuclear plant

Portland, Ore.–based NuScale Power has signed a memorandum of understanding with Kozloduy Nuclear Power Plant–New Build Plc (KNPP-NB) to discuss the possible deployment of NuScale’s small modular reactor technology at Bulgaria’s Kozloduy site. KNPP-NB was established in 2012 to commission new nuclear power capacity at Kozloduy.

Specifics: Under the MOU, NuScale will support KNPP-NB as it analyzes the suitability of NuScale’s SMRs for Kozloduy, located in northwest Bulgaria. The analysis will include the development of a project time line “with milestone deliverables for a feasibility study” and a project-specific cost estimate, as well as engineering, planning, licensing, and other activities, according to a February 17 NuScale press release.

NextEra Energy will be allowed to revise the emergency preparedness plan for its Duane Arnold nuclear power plant to reflect the plant’s decommissioning status, having been granted exemptions from the Nuclear Regulatory Commission’s emergency preparedness and planning requirements, the agency announced on February 17. A single-unit boiling water reactor plant located in Palo, Iowa, approximately eight miles northwest of Cedar Rapids, Duane Arnold was shut down in August 2020 after a derecho damaged the plant’s cooling towers.

The NRC regularly issues exemptions from its licensing requirements to nuclear power plants that are transitioning to decommissioning, where the risk of an off-site radiological release is significantly lower, and the types of possible accidents significantly fewer, than at an operating reactor.

Once NextEra implements the exemptions, state and local governments can rely on comprehensive emergency management (“all hazard”) planning for off-site emergency response should an event occur at Duane Arnold. As a result, there will not be a 10-mile emergency planning zone as currently identified in Duane Arnold’s license. The plant will maintain an on-site emergency plan and response capabilities, including the continued notification of state government officials in the event of an emergency declaration.

NASA mission control and space science fans around the world celebrated the safe landing of the Mars 2020 Perseverance rover on February 18 after a journey of 203 days and 293 million miles. Landing on Mars is difficult—only about 50 percent of all previous Mars landing attempts have succeeded—and a successful landing for Perseverance, the fifth rover that NASA has sent to Mars, was not assured. Confirmation of the successful touchdown was announced at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., at 3:55 p.m. EST.

“This landing is one of those pivotal moments for NASA, the United States, and space exploration globally—when we know we are on the cusp of discovery and sharpening our pencils, so to speak, to rewrite the textbooks,” said acting NASA administrator Steve Jurczyk. “The Mars 2020 Perseverance mission embodies our nation’s spirit of persevering even in the most challenging of situations, inspiring, and advancing science and exploration. The mission itself personifies the human ideal of persevering toward the future and will help us prepare for human exploration of the Red Planet.”

Only radioisotope thermoelectric generators (RTG) can provide the long-lasting, compact power source that Perseverance needs to carry out its long-term exploratory mission. Perseverance carries an RTG powered by the radioactive decay of plutonium-238 that was supplied by the Department of Energy. ANS president Mary Lou Dunzik-Gougar and CEO and executive director Craig Piercy congratulated NASA after the successful landing, acknowledging the critical contributions of the DOE’s Idaho National Laboratory, Oak Ridge National Laboratory, and Los Alamos National Laboratory.

Maybe everything really is bigger in Texas, but that’s not necessarily a good thing. The brutal winter storm that hit much of the country earlier this week struck the Lone Star State with particular severity, leaving the power grid in shambles and millions of Texas residents without power, in many instances for days. On Tuesday, at the height of the power crisis, more than 4.4 million utility customers were without access to electricity, according to poweroutage.us.

Coordinated federal and private industry investments made now could yield an operational fusion pilot plant in the 2035–2040 time frame, according to Bringing Fusion to the U.S. Grid, a consensus study report released February 17 by the National Academies of Sciences, Engineering, and Medicine (NASEM).

Developed at the request of the Department of Energy, the report builds on the work of the 2019 Final Report of the Committee on a Strategic Plan for U.S. Burning Plasma Research, and it identifies key goals, innovations, and investments needed to develop a U.S. fusion pilot plant that can serve as a model for producing electricity at the lowest possible capital cost.

“The U.S. fusion community has been a pioneer of fusion research since its inception and now has the opportunity to bring fusion to the marketplace,” said Richard Hawryluk, associate director for fusion at the Princeton Plasma Physics Laboratory and chair of the NASEM Committee on the Key Goals and Innovations Needed for a U.S. Fusion Pilot Plant, which produced the report.

A Montana Senate committee last week passed a joint resolution calling for the creation of a legislative panel to study the feasibility of replacing the coal-fired units at the state’s Colstrip power plant with advanced small modular reactors.

Two of Colstrip’s four coal boilers were permanently closed in January 2020, and most energy-sector observers expect the remaining two units to be retired within the next few years, given coal’s declining prospects in states such as Washington, which has passed legislation banning utilities from using coal power after 2025.

The resolution, known as SJ3, also calls on the panel to evaluate current Montana regulations that need revision in order to enable the construction and operation of advanced nuclear reactors. The study would need to be concluded before September 15, 2022.

The Canadian province of New Brunswick has awarded C$20 million (about $15.7 million) to ARC Clean Energy Canada (ARC Canada) to support the development of the proposed ARC-100 advanced small modular reactor. The premier of New Brunswick, Blaine Higgs, announced the award during his state of the province address on February 10.

ARC Canada, headquartered in Saint John, New Brunswick, is a subsidiary of U.S.-based ARC Clean Energy, formerly known as Advanced Reactor Concepts. The company’s ARC-100 is a 100-MWe integrated sodium-cooled fast reactor that uses a metallic uranium alloy fuel. Based on Argonne National Laboratory’s Experimental Breeder Reactor-II, the reactor is designed to operate for 20-plus years without refueling.

In October 2019, ARC Canada announced that it had completed the first phase of the Canadian Nuclear Safety Commission’s (CNSC) vendor design review. (While the phase-one assessment provides detailed feedback regarding a vendor’s understanding of the CNSC’s requirements for a nuclear power plant in Canada, it does not certify the design or license the reactor.)

The Department of Energy’s Idaho National Laboratory is celebrating the scheduled landing of the Perseverance rover on the surface of Mars in just two days’ time with a live Q&A today, February 16, from 3 p.m. to 4:30 p.m. EST).

INL and Battelle Energy Alliance, its management and operating contractor, are already looking ahead to the next generation of plutonium-powered spacecraft: the Dynamic Radioisotope Power System (Dynamic RPS). INL announced on February 15 that it is partnering with NASA and the DOE to seek industry engagement to further the design of this new power system.

The Department of Energy has extended the public review and comment period for the Draft Versatile Test Reactor Environmental Impact Statement (DOE/EIS-0542) through March 2, 2021.

The DOE issued the draft EIS for the Versatile Test Reactor (VTR) for comment on December 21, 2020. The draft document identifies Idaho National Laboratory as the DOE’s preferred location for the VTR, a proposed sodium-cooled fast-neutron-spectrum test reactor that, according to the DOE, will enhance and accelerate research, development, and demonstration of innovative nuclear energy technologies.

In August 2020, Battelle Energy Alliance, which operates INL for the DOE, began contract negotiations with a Bechtel National–led team that includes TerraPower and GE Hitachi Nuclear Energy to support the design and construction of the VTR.

Honeywell plans to resume production at its Metropolis Works uranium conversion facility in 2023 and will begin preparations for the restart this year, the company has announced. The plant is in Metropolis, Ill.

Honeywell, based in Charlotte, N.C., said in a February 9 statement that it plans to hire 160 full-time employees, as well as contractors, by the end of 2022, adding, “We’re proud to bring these jobs back to the Metropolis community to meet the needs of our customers.”

Idled in early 2018, the plant is the nation’s sole uranium conversion facility.

To mark the International Day of Women and Girls in Science, the U.S. Postal Service today issued a commemorative Forever stamp recognizing influential nuclear physicist and professor Chien-Shiung Wu (1912–1997).

A great honor: The stamp was dedicated during a virtual ceremony that can be viewed on the Postal Service Facebook and Twitter pages. USPS official Kristin Seaver was joined for the ceremony by Vincent Yuan, a scientist at Los Alamos National Laboratory and son of the honoree; Jada Yuan, granddaughter of the honoree; and Brian Greene, professor of physics and mathematics at Columbia University. The stamp is available for purchase at Post Office locations nationwide and online.

“I am elated to have my mother honored by USPS on a postage stamp because I believe it goes beyond recognizing her scientific achievements; it also honors the determination and moral qualities that she embodied,” said Vincent Yuan. “It’s even more profound that the recognition comes from America, the country of her naturalization that she loved.”
