Citing the mishandling of the COVID-19 pandemic, the Bulletin of the Atomic Scientists’ Science and Security Board kept the Doomsday Clock at 100 seconds to midnight, remaining as near to midnight as it has ever been.

“The mishandling of this grave global health crisis is a ‘wake-up call’ that governments, institutions, and a misled public remain unprepared to handle the even greater threats posed by nuclear war and climate change,” a press release from the Bulletin stated. The group also cited a lack of progress in 2020 in dealing with nuclear and climate perils as the reason for not moving the Doomsday Clock from its 2020 position.

The U.S. House of Representatives Committee on Science, Space, and Technology is leading a one-day social media campaign today to highlight the importance of leading with science and scientific solutions as the committee works to provide support for science and the scientific community. The “tweetstorm” will run from noon to 5 p.m. (EST) and will involve a variety of science-related organizations, including the American Nuclear Society.

Organizations are being asked to post messages on their social media accounts (Facebook, Instagram, and Twitter) related to five categories:

• American leadership in STEM
• Environmental justice
• Combating the climate crisis
• Scientific integrity
• COVID-19

Three hashtags have been created for the campaign: #ScientificSolutions, #SolvingtheClimateCrisis, and #EnvironmentalJusticeforAll.

Five former chairmen of the U.S. Nuclear Regulatory Commission—Stephen Burns, Allison Macfarlane, Nils Diaz, Richard Meserve, and Dale Klein—signed a letter to José Romero, Arkansas health secretary and chair of the Centers for Disease Control and Prevention (CDC) immunization advisory committee, requesting that the advisory committee update its recommendation for COVID-19 vaccine allocation guidance for the energy workforce (including nuclear energy workers).

Currently, the CDC has four phases for the COVID-19 vaccine rollout. Those phases are numbered:

• 1a (the current phase), reserved for healthcare workers and those living in long-term care facilities;
• 1b, reserved for people 75 years and older and frontline essential workers;
• 1c, reserved for persons 65 to 74 years old, those aged 16 to 64 who have high-risk medical conditions, and other categories of essential workers (this includes energy workers); and
• 2, for everyone else that was not named in the previous three phases aged 16 to 64.

The government of the United States should throw its muscle behind ramping up a mammoth, rapid rollout of all forms of renewable energy through Operation Warp Speed, similar to what is being done with COVID-19, Clive Thompson writes in an Ideas column for Wired.

The rollout should include energy sources that we already know how to build—like solar and wind — but also experimental emerging sources such as geothermal and small nuclear, and cutting-edge forms of energy storage or transmission.

Largely as a result of the continuing COVID-19 crisis, the Vogtle reactor-construction project team expects to further adjust dates for achieving key project milestones, including the start of hot functional testing and fuel load for Unit 3, Southern Company subsidiary Georgia Power announced on January 11.

The company added, however, that it continues to expect to bring Unit 3 into service this November and Unit 4 into service in November 2022. Additional updates on the project will be provided during Southern’s quarterly earnings call next month.

• ARDP picks divergent technologies in Natrium, Xe-100: Is nuclear’s future taking shape? The Department of Energy has put two reactor designs—TerraPower’s Natrium and X-energy’s Xe-100—on a fast track to commercialization, each with an initial $80 million in 50-50 cost-shared funds awarded through the Advanced Reactor Demonstration Program.

Adequate uranium resources exist to support the long-term, sustainable use of nuclear energy for low-carbon electricity generation, as well as for other applications, including hydrogen production. That assessment is contained in the latest (28th) edition of Uranium—Resources, Production and Demand, a global, biennial reference prepared jointly by the OECD Nuclear Energy Agency and the International Atomic Energy Agency.

The publication adds, however, that the impact of the COVID-19 pandemic and recent reductions in uranium production and exploration could affect available supplies, suggesting that timely investment in innovative mining and processing techniques would help assure that uranium resources are brought to market when needed.

The COVID-19 pandemic hit the United States on a wide basis in March of this year, and life as we knew it changed. “Social distancing” and “essential workers” entered the jargon and working from home for many became the norm.

The number of remote meetings skyrocketed, and various companies have seen that business can be conducted without having employees in the office.

For universities, distance learning has been common for a while now, but with COVID it has become essential.

Nuclear News asked some nuclear engineering professors about how their programs have been dealing with the pandemic. We posed three questions and asked for responses to any or all of them:

How has COVID affected your NE program, and what have you learned from the experience?

Has your NE program been able to contribute to your university’s broader COVID response (e.g., through research or volunteer programs)?

What opportunities or challenges do you foresee in the next year for your program and your students?

The following are responses received by NN.

The levelized costs of electricity generation from low-carbon technologies, including nuclear, are dropping and are increasingly below that of conventional fossil fuel generation, concludes a new report from the International Energy Agency and the OECD Nuclear Energy Agency (NEA).

The 223-page report, Projected Costs of Generating Electricity—2020 Edition, the ninth such jointly produced analysis, includes plant-level cost data on power generation from nuclear, natural gas, coal, and a variety of renewable sources, including wind, solar, hydro, and biofuels. The report provides data from 243 plants in 24 countries.

In testimony filed last week with the Georgia Public Service Commission, Georgia Power and Southern Nuclear acknowledge that the “aggressive” target dates set in July for some of the Vogtle construction project’s upcoming milestones have had to be pushed back by a few months. At the same time, however, the companies continue to express confidence in being able to meet the regulatory-approved commercial start dates for the new reactors—November 2021 for Unit 3 and November 2022 for Unit 4.

The testimony was filed in support of Georgia Power’s Twenty-third Semi-annual Vogtle Construction Monitoring Report, released in August, which covers the period from January 1 to June 30, 2020.

Bruce Power announced on October 22 that it has completed its second harvest of cobalt-60 this year during an outage of Unit 8 of the Bruce nuclear power plant in Kincardine, Ontario, Canada. The company said that with this latest harvest, it will have provided the world enough of the medical isotope to sterilize 20 billion–25 billion pairs of gloves or COVID-19 swabs.

The Co-60 will be sent to Ottawa-based Nordion for processing and distribution over the next several weeks, according to Bruce Power. From there, the isotope will be shipped around the world for use in gamma irradiation to sterilize medical devices such as single-use gowns, surgical gloves, scalpels, syringes, and other critical health care equipment.

Speaking last week at a virtual event of the Empire Club of Canada, Bruce Power president and chief executive officer Mike Rencheck announced “NZ-2050”—the company’s strategy for helping Canada achieve its stated goal of net-zero emissions by 2050.

Canada’s only private sector nuclear generator, Bruce Power operates the Bruce Nuclear Generation Station, located in Kincardine, Ontario. The plant houses eight units, all CANDU pressurized heavy-water reactors, with a total output of 6,288 MWe.

The International Energy Agency released its annual World Energy Outlook on October 13, noting the massive disruption caused by the COVID-19 pandemic and calling for a surge in well-designed energy policies to put the world on track for a resilient energy system that can meet climate goals.

According to the latest IEA analysis of the pandemic’s impact, drops are expected in 2020 in global energy demand by 5 percent, energy-related CO2 emissions by 7 percent, and energy investment by 18 percent. This year’s report focuses on the pivotal period of the next 10 years, exploring four different pathways out of the crisis.

More information on the report is available here. The full publication can be purchased for €120 (about $140).

“Given the scale and urgency of the climate challenge, we do not have the luxury of excluding nuclear from the tools at our disposal,” the leaders of the International Energy Agency and the International Atomic Energy Agency wrote in an op-ed article posted on the CNN website last Friday.

Fatih Birol, executive director of the IAE, and Rafael Mariano Grossi, director general of the IAEA, said that the COVID-19 crisis not only delivered an unprecedented shock to the world economy, it also underscored the scale of the climate challenge the world faces: Even in the current deep recession, global carbon emissions remain unsustainable.

With special precautions in place due to the COVID-19 pandemic, the International Atomic Energy Agency commenced its week-long 64th General Conference yesterday with a plenary session that included remarks from Rafael Mariano Grossi, the agency’s director general.

“The latest IAEA annual projections show that nuclear power will continue to play a key role in the world’s low-carbon energy mix, with global nuclear electrical capacity seen nearly doubling by 2050 in our high-case scenario,” Grossi said, referring to a recently released agency report. “Climate change mitigation remains a key potential driver for maintaining and expanding the use of nuclear power.”

The IAEA conference runs through September 25.

Tokyo-based Hitachi Ltd. today announced that it is withdrawing from the currently suspended Wylfa Newydd nuclear-build project in northwestern Wales. The announcement dashes the hopes raised last month by reports that Horizon Nuclear Power, the Hitachi subsidiary in charge of the project, was in talks with the U.K. government regarding a possible resuscitation.

Hitachi had put the project on hold some 20 months ago, and in today’s announcement the company cited the length of the suspension and the COVID-19 investment environment as factors in its decision.

The latest phase of the Darlington nuclear power plant’s refurbishment project began last week with the start of the defueling of Unit 3, according to Ontario Power Generation (OPG). Originally scheduled to begin in May this year, Unit 3’s refurbishment was postponed due to the COVID-19 pandemic.

Located in Clarington, Ontario, Canada, the Darlington plant houses four 878-MWe CANDU pressurized heavy-water reactors, all of which entered commercial operation in the early 1990s. The 10-year refurbishment project—which was 10 years in the planning—commenced in earnest in October 2016, when Unit 2 was taken off line (NN, Dec. 2016, pg. 45). The refurbished Unit 2 was returned to service in early June, and in late July Unit 3 was shut down and disconnected from the grid in preparation for its refurbishment.

Kazatomprom, Kazakhstan’s state-owned uranium production company, will continue “flexing down” production by 20 percent through 2022, compared to the planned levels under subsoil use contracts, the company announced last week. It will also maintain its 20 percent reduction against subsoil use contracts in 2021, with no additional production planned to replace volumes lost in 2020 due to measures taken to combat COVID-19.

Kazatomprom does not expect to return to full subsoil use contract production levels until a sustained market recovery is evident and demand and supply conditions signal a need for more uranium, the company noted.
