Advanced Nuclear Fuel Cladding: Innovative Materials Enhance Fleet Safety and Performance
The Nuclear Regulatory Commission recently issued a draft safety evaluation report indicating initial acceptance of Kairos Power’s source term methodology for its fluoride salt–cooled high-temperature reactor (KP-FHR).
Nordhaus
Macfarlane
As noted by Newswire yesterday, former Nuclear Regulatory Commission chairman Allison Macfarlane describes herself as “agnostic” on the subject of nuclear energy. In the view of some, however, there is a more accurate way to describe Macfarlane’s nuclear stance.
In a November 15 blog post, Breakthrough Institute cofounder Ted Nordhaus suggests that Macfarlane can be considered a face of the modern antinuclear movement, the typical representative of which, he says, is not “a hippie with a No Nukes sign,” but rather “a highly credentialed progressive policy wonk, a lawyer, or academic, or journalist, who often claims not to be opposed to nuclear energy at all.”
Bellevue, Wash.–based TerraPower has selected Kemmerer, Wyo., as the preferred site for its Natrium reactor demonstration project, the company announced yesterday.
Sabga
Macfarlane
In an interview with Al Jazeera Digital, former Nuclear Regulatory Commission chairman and self-proclaimed nuclear agnostic Allison Macfarlane said that untested advanced reactor designs and the high cost of building new power plants will limit nuclear’s ability to play a critical role in fighting the climate crisis, at least in the near future.
“Almost 19 percent of the power [in the United States] right now is produced by nuclear power. That’s carbon free. That’s really helpful. We don’t want to shut that off,” Macfarlane told Al Jazeera Digital’s managing business editor Patricia Sabga. “But I live in a pragmatic, realistic world. And I don’t think, at least in the next 10 or 20 years, that nuclear power will be able to have a big impact on reducing carbon emissions because we can’t build new plants fast enough.”

The second of the twin reactors making up the Shidaowan nuclear power plant’s high-temperature gas-cooled reactor pebble-bed module (HTR-PM) demonstration project reached initial criticality on November 11, China Huaneng Group has announced.
The milestone was achieved two months after the HTR-PM’s first unit had reached initial criticality. The two 200-MWe reactors are connected to a single steam turbine.
China Huaneng holds a 47.5 percent stake in the HTR-PM, with the remaining shares distributed between China Nuclear Engineering Corporation (32.5 percent) and Tsinghua University (20 percent). Construction of the facility, located in northeast China’s Shandong Province, began in 2012, led by Chinergy, a joint venture between CNEC and Tsinghua.
In April, President Biden announced a new U.S. climate target: a 50–52 percent reduction in greenhouse gas emissions below 2005 levels by 2030. It’s an ambitious goal, and one that’s right up there with recent climate declarations from Canada, the European Union, and the United Kingdom. It’s also one that, according to a new analysis from the Electric Power Research Institute, will require immediate action across all sectors of the economy.
Key findings of the EPRI report Strategies and Actions for Achieving a 50% Reduction in U.S. Greenhouse Gas Emissions by 2030 include the following:
Hot functional testing at Unit 3 of Pakistan’s Karachi nuclear power plant has been completed ahead of schedule, and the reactor has entered the fuel loading stage, China National Nuclear Corporation announced on November 11.
Macron
In a televised address Tuesday evening, French president Emmanuel Macron announced his government’s intention to build new large nuclear reactors in France to address growing energy and environmental challenges.
“If we want to pay for our energy at reasonable rates and not depend on foreign countries, we must both continue to save energy and invest in the production of carbon-free energy on our soil,” said Macron. “This is why, to guarantee France’s energy independence, to guarantee our country’s electricity supply, and to reach our goals—notably carbon neutrality in 2050—we will for the first time in decades revive the construction of nuclear reactors in our country and continue to develop renewable energy. These investments will allow us to live up to our commitments. As we close COP26 in Glasgow, this is a strong message from France.”
The Interior Department’s U.S. Geological Survey (USGS) this week revealed its draft revised list of critical minerals—those deemed essential to economic and national security—and uranium is not on it.
The list was initially developed in 2018 in response to a December 2017 Trump administration executive order. Uranium was included as one of 35 minerals on that list.
The Nuclear Regulatory Commission has issued for public comment a draft environmental impact statement on NextEra Energy’s application for the subsequent license renewal of its Point Beach reactors, located in Two Rivers, Wis. Subsequent license renewal allows a reactor to operate for 20 years beyond the expiration of its original license renewal.
French nuclear reactor company Framatome has completed its purchase of Rolls-Royce Civil Nuclear Instrumentation and Control. Framatome announced in December 2020 that it had agreed to acquire Rolls-Royce’s I&C business, which has operations in France, the Czech Republic, and China.
According to Framatome, the transaction builds on the company’s engineering expertise, enlarges its industrial footprint, and expands its global I&C systems development and deployment capabilities.
The construction of Unit 3 at the United Arab Emirates’ Barakah nuclear power plant has been completed, the Emirates Nuclear Energy Corporation (ENEC) announced yesterday on the sidelines of COP26, the high-profile climate confab taking place in Scotland this week and next.
According to ENEC’s announcement, Barakah-3 will now undergo operational readiness activities and is on track to start up in 2023.
Crane
Exelon, owner and operator of the nation’s largest nuclear reactor fleet, has made clear its position on the massive infrastructure and social spending bills that federal lawmakers, at this writing, continue to haggle over.
“As world leaders convene in Glasgow for COP26 to address the climate crisis, the need for America to take action has never been more urgent,” said Chris Crane, Exelon’s president and chief executive officer, on Monday. “The bipartisan infrastructure agreement and the policy framework for Build Back Better legislation will make us more competitive globally, spur innovation and support good-paying jobs, protect current and future generations from the worst impacts of climate change, and cement America’s leadership on one of the most pressing challenges—and opportunities—of our time. The time to act is now, and we encourage lawmakers to pass these critical policies into law.”
Nuclear power provided about 70 percent of the electricity for the COP26 meeting in Glasgow on Tuesday, according to data from National Grid’s Carbon Intensity API.
Nuclear output from the Torness and Hunterston B power plants, supported by wind power, gave the southern Scotland region, which includes Glasgow, the lowest carbon electricity in the United Kingdom. Other parts of the country, which lack nuclear and renewable capacity, had to burn coal and gas to meet most of their electricity demand.
On the sidelines of the COP26 Conference in Glasgow yesterday, John Kerry, the Biden’s administration’s special presidential envoy for climate, joined Romanian president Klaus Iohannis to announce plans to build a first-of-a-kind small modular reactor plant in Romania. The SMR technology is to be provided by NuScale Power, based in Portland, Ore.
Bryukhanov
Viktor Bryukhanov, the man blamed for the Chernobyl disaster, has died at age 85.
Bryukhanov was in charge of the Chernobyl plant in Ukraine when the devastating accident occurred in 1986. Afterward, he was held responsible and was imprisoned.
Bryukhanov's death, on October 13 in Kiev, Ukraine, was announced by a representative of the now-closed nuclear plant, according to a report in the New York Times. He had suffered from Parkinson’s disease, in addition to having had several strokes following his retirement in 2015.
The sentencing: In 1987, Bryukhanov was found guilty of gross violation of safety regulations, creating conditions that led to the steam explosion that released a radioactive dust cloud into the atmosphere. Reports also mentioned that he failed to ensure correct and firm leadership in the difficult conditions of the accident and displayed irresponsibility and inability to organize. He was sentenced to 10 years in a labor camp along with a five-year sentence for abuse of power, which ran concurrently.
The STP Nuclear Operating Company operates the South Texas Project Electric Generating Station, located eight miles west of Wadsworth, Texas. One of STP’s core values is innovation—a value that is evident in the organization’s 2021 Nuclear Energy Institute Top Innovative Practice (TIP) award–winning mobile work management (MWM) platform, which strives to utilize technology to bring efficiency to the field for nuclear professionals.
Steven P. Nesbit
Depending on where you reside on this nuclear technology world of ours, you may care a great deal, or not at all, about who happens to be sitting on the Nuclear Regulatory Commission at any given point in time. If you live on the Department of Energy continent or the Academia continent, it’s probably not a big deal. If you are on the Nuclear Power Plant Operator continent or the Vendor continent (which are actually part of the same landmass), it is quite important. If you are on the NRC island, it’s huge.
The NRC comprises five presidentially appointed, U.S. Senate–confirmed commissioners who are commonly referred to as “the Commission,” and approximately 3,000 federal employees referred to as the staff. The Commission oversees the NRC staff; together, they license and regulate the nation’s civilian use of radioactive materials to provide reasonable assurance of adequate protection of public health and safety. The president of the United States designates one of the commissioners to serve as chairman, the principal executive officer of and the official spokesperson for the agency.
A new survey by the research and consulting firm BVA Group for France’s Orano finds an increased acceptance of nuclear energy among the French people from two years ago. (BVA conducted a similar poll for the nuclear fuel cycle company in 2019.)
In what has become for nuclear advocates an all-too-familiar refrain, Georgia Power has made another revision to the Vogtle nuclear expansion project schedule. The company now predicts a Unit 3 in-service date in the third quarter of 2022 and a Unit 4 in-service date in the second quarter of 2023, representing a three-month shift for each unit.
