Granholm

Energy Secretary Jennifer Granholm on Wednesday during the CERAWeek energy conference commented that Texas should look beyond its borders to join other grids following last month's winter storm that left millions without power, according to an article from The Hill.

“It would be great for Texas to consider connecting ... to its neighbors,” she said. “I understand the go-it-alone sort of ethos, but there’s also an ethos of helping your neighbor too and I think connecting could benefit Texas in times of emergency, but it could also benefit Texas and the rest of the country in good times when Texas is generating all sorts of clean energy."

The House of Representatives produced some good news for the nation’s uranium mining industry in late February, but also some of the opposite variety.

Latta

First, on February 25, Rep. Bob Latta (R, Ohio) reintroduced the Nuclear Prosperity and Security Act (H.R. 1351), initially brought forward by the congressman last July. The bill would direct the secretary of energy to establish and operate a uranium reserve in the United States to ensure the availability of the element in the event of a market disruption and to support U.S. strategic fuel cycle capabilities.

“The United States has fallen behind in the competitive development of nuclear energy, and now we rely heavily on foreign sources of uranium,” Latta stated. “In order to avoid threats to our nuclear supply chain, we need to build up our domestic uranium mining, production, and conversion by establishing a uranium reserve. The Nuclear Prosperity and Security Act would establish a domestic uranium reserve that will result in lower carbon emissions, new jobs and economic growth, and a more secure world.”

H.R. 1351 has been referred to the House Energy and Commerce Committee.

Virginia’s nuclear-sector stakeholders, led by the Virginia Nuclear Energy Consortium Authority (VNECA), have drawn up a plan for helping the state reach its goal of 100 percent carbon-free electricity generation by 2045.

Released late last month, Virginia is Nuclear: 2020–2024 Strategic Plan is the result of legislation, SB 549, signed into law last year. The law directed the state’s Department of Mines, Minerals and Energy; Secretary of Commerce and Trade; and Secretary of Education to work with VNECA and the Virginia Economic Development Partnership Authority to develop a comprehensive blueprint for the role of nuclear energy in Virginia’s overall clean-energy strategy.

“The nuclear industry is vital to Virginia, and the Lynchburg region in particular,” said state Sen. Stephen Newman, who sponsored SB 549. “Jobs, economic growth, and clean air are just three of the benefits the state will see from the plan. I am proud of the industry and look forward to seeing them move forward with the plan.”

The Tennessee Valley Authority has begun a refueling and maintenance outage at Browns Ferry-2 that includes the largest scope of turbine deck work since the unit’s construction, as well as innovations in fuel assembly components, the utility announced on March 1.

On deck: All three of the 1,254.7-MWe boiling water reactor’s low-pressure turbines will undergo a comprehensive replacement of major components, including new rotors, inner casings, steam piping and bellows, and turbine supervisory instruments, requiring the support of more than 500 additional outage workers. TVA said that 600 crane lifts will need to be performed for some components, such as the rotors, which weigh up to 327,888 lb., and inner casings, which weigh up to 200,000 lb.

The Nuclear Innovation Alliance (NIA) and the Partnership for Global Security (PGS) have released a joint report laying out a comprehensive strategy for U.S. leadership in the commercialization of next-generation nuclear power.

The 34-page report, U.S. Advanced Nuclear Energy Strategy for Domestic Prosperity, Climate Protection, National Security, and Global Leadership, says that collaboration between government, industry, civil society, and other nations can bring advanced reactors to market to reduce global emissions, provide domestic jobs, and support national security.

The report was released with a 58-minute webinar available on YouTube.

It was a rather normal day back on March 11, 2011, at the Fukushima Daiichi nuclear plant before 2:45 p.m. That was the time when the Great Tohoku Earthquake struck, followed by a massive tsunami that caused three reactor meltdowns and forever changed the nuclear power industry in Japan and worldwide. Now, 10 years later, much has been learned and done to improve nuclear safety, and despite many challenges, significant progress is being made to decontaminate and defuel the extensively damaged Fukushima Daiichi reactor site. This is a summary of what happened, progress to date, current situation, and the outlook for the future there.

The latest episode in the continuing saga of the failed nuclear expansion project at South Carolina’s Summer plant played out in federal court last week when the former chief executive officer of SCANA, Kevin Marsh, pleaded guilty to charges of fraud. According to the state attorney general’s office, Marsh will serve two years of a 10-year sentence, followed by three years of probation, provided he continues to cooperate with prosecutors. Marsh will also part with $5 million, which is to be used to help low-income ratepayers with their utility bills.

“This case is a good example of the power of our state grand jury and how our office uses it to hold the powerful accountable,” said South Carolina attorney general Alan Wilson. “While this criminal proceeding is not meant to repay the customers who spent billions of dollars on nuclear plants that were never finished, we hope they take some comfort from the fact that the former CEO of SCANA has pled guilty for his role in this debacle. A public utility and its officers must serve the public.”

Several antinuclear groups and the State of Michigan have filed petitions to intervene in the transfer of the Palisades nuclear power plant license from Entergy to Holtec International for decommissioning following the plant’s permanent shutdown and defueling in the spring of 2022.

Spurred by last week’s power grid failure in Texas, the Federal Energy Regulatory Commission on Monday announced that it will open a new proceeding to examine the threat that climate change and extreme weather events pose to electric reliability. The proceeding, FERC said, will investigate how grid operators prepare for and respond to these events, including droughts, extreme cold, wildfires, hurricanes, and prolonged heat waves.

Manchin

Speaking at a U.S. Senate committee meeting this week, Sen. Joe Manchin (D., W.V.) said that continuing support for nuclear energy would be essential in meeting the country’s goals of reducing the emissions that fuel climate change, according to the Politico Pro newsletter.

Details: Manchin, who heads the U.S. Senate Energy and Natural Resources Committee, was highly critical of anyone suggesting that climate change can be addressed without nuclear energy being in the mix.

Granholm

The Senate earlier today confirmed Jennifer Granholm as the nation’s 16th secretary of energy. The final tally was 64–35, with several Republicans joining Democrats in support of the former Michigan governor. Granholm becomes the second woman (after the Clinton administration’s Hazel O’Leary) to hold the post.

Picked to helm the Department of Energy last December by then president-elect Biden, Granholm testified before the Senate Energy and Natural Resources Committee on January 27, and on February 3, the committee voted 13–4 to advance her nomination.

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.

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.

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.
