The Environmental Protection Agency has issued its final permits for Canada-based Azarga Uranium’s underground injection control (UIC) activities at the Dewey Burdock in situ recovery (ISR) uranium project in South Dakota, the company announced recently.

The EPA’s action includes two permits: a UIC Class III Area Permit for the ISR of uranium and a UIC Class V Area Permit for deep injection wells that will be used to dispose of ISR-process waste fluids after they have been treated to meet radioactive waste and hazardous waste standards.

The EPA is also finalizing an aquifer exemption approval in connection with the Class III permit to allow for resource recovery in the uranium-bearing portions of the Inyan Kara group of aquifers.

The scheduled premature shutdown of Indian Point-3 will all but guarantee a massive increase in fossil fuel use, according to an op-ed written by American Nuclear Society President Mary Lou Dunzik-Gougar and Executive Director/CEO Craig Piercy that was published in the New York Daily News on November 30.

Indian Point-3 is slated to be shut down in April 2021, four years before its operating license expires.

EDF Energy has made a “proactive decision” to move Britain’s Hinkley Point B power station into its defueling phase no later than July 15, 2022—some eight months earlier than previously scheduled—the company announced on November 19.

The two-unit plant, located in Somerset, England, began generating electricity in 1976 and has since produced more than 300 TWh of power, enough to meet the electricity requirements of every home in the United Kingdom for three years, according to EDF.

The November issue of Nuclear News is focused on the individuals who make up our nuclear community.

We invited a small group of those individuals to tell us about their day-to-day work in some of the many occupations and applications of nuclear science and technology, and they responded generously. They were ready to tell us about the part they play, together with colleagues and team members, in supplying clean energy, advancing technology, protecting safety and health, and exploring fundamental science.

In these pages, we see a community that can celebrate both those workdays that record progress moving at a steady pace and the exceptional days when a goal is reached, a briefing is delivered, a contract goes through, a discovery is made, or an unforeseen challenge is overcome.

The Nuclear News staff hopes that you enjoy meeting these members of our community—or maybe get reacquainted with friends—through their words and photos.

A final report on the dry storage and transportation of high-burnup spent nuclear fuel (NUREG-2224) has been issued by the Nuclear Regulatory Commission. NUREG-2224 provides a technical basis in support of the NRC’s guidance on adequate fuel conditions as it pertains to hydride reorientation in the cladding of high-burnup spent fuel (over 45 gigawatt-day per metric ton uranium).

NUREG-2224, “Dry Storage and Transportation of High Burnup Spent Nuclear Fuel,” was made publicly available on November 23 on the NRC’s ADAMS website with Accession No. ML20191A321.

Ontario Power Generation (OPG) recently announced the resumption of planning activities for future nuclear power generation at its Darlington site, with a goal of hosting a grid-size small modular reactor as soon as 2028. Originally, plans for the Darlington new nuclear project were focused on the construction of traditional large reactors.

Located in Clarington, Ontario, Darlington is the only site in Canada currently licensed for new nuclear. OPG was granted a license from the Canadian Nuclear Safety Commission (CNSC) in 2012 to allow site preparation activities for the project. The company has applied to renew the license, which is set to expire in August 2022. The CNSC will hold a public hearing on June 9–10, 2021, to consider the license renewal.

Early last month, OPG announced that it was working with three grid-scale SMR technology developers—GE Hitachi, Terrestrial Energy, and X-energy—to advance engineering and design work, with the goal of identifying options for future deployment.

Robotics and remote systems have been used for supporting nuclear facilities since the dawn of the atomic age. Early commercial nuclear plants implemented varying levels of automation and remote operation, such as maintenance activities performed on the reactor pressure vessel and steam generators. Over the past several decades, there has been a steady progression toward incorporating more advanced remote operations into nuclear plants to improve their efficiency and safety. One of the primary forces driving the adoption of robotic tooling in U.S. nuclear power plants is money.

The economic model for the U.S. operating fleet has changed considerably over the past 10 to 12 years. Regulations in the nuclear industry have rarely decreased and, more often than not, have increased. This has led to nuclear plants in certain energy markets being hindered financially and thus needing to find ways to optimize their operations to do more with the resources they have. At the same time, the reliability and flexibility of robotics and automated systems have been increasing while their costs have been decreasing, making robotic systems much safer and more available to use. This has helped drive utilities to explore new ways of using robotics to overcome the obstacles they are facing. One of the obstacles that power plants have been tackling has been shortening the duration of their refueling outages to decrease their costs and increase their revenue.

The Senate Appropriations Committee last week released all 12 fiscal year 2021 appropriation measures and subcommittee allocations, including an Energy and Water Development bill that provides $150 million for establishing a U.S. uranium reserve, the same amount requested by the Trump administration in its February budget estimate.

The committee’s Republican majority decided to bypass the usual markup and full Senate consideration of the bills and instead proceed directly to negotiations with the House, in hopes of passing an omnibus bill by the December 11 deadline to avoid a government shutdown.

Shelby

“By and large, these bills are the product of bipartisan cooperation among members of the committee,” said Sen. Richard Shelby (R., Ala.), chairman of the Appropriations Committee. “As negotiations with the House begin in earnest, I look forward to working with Chairwoman Lowey, Vice Chairman Leahy, and Ranking Member Granger to resolve our differences in a bipartisan manner.”

The Leningrad nuclear power plant’s Unit I-2, a 925-MWe RBMK-1000 light-water–cooled graphite-moderated reactor, was permanently shut down on November 10, according to Rosatom, Russia’s state atomic energy corporation. The shutdown occurred at 12:30 a.m. Moscow time.

The unit was the oldest operating reactor at the plant, having achieved initial criticality in May 1975 and entered commercial operation in February 1976. Two additional RBMK-1000s remain in operation at Leningrad—Units I-3 and I-4, both of which have been in operation for about 40 years.

The retired reactor is to be replaced by Unit II-2, one of two 1,085-MWe Generation III+ VVER-1200 pressurized water reactors at the Leningrad site. The new unit was connected to the Russian grid in October, and on November 6 it received regulatory approval to begin pilot operation. (Leningrad’s other VVER-1200, Unit II-1, started commercial operation in 2018.) Following the trial operation, Unit II-2 will be shut down for an additional equipment inspection by a state commission before being put into commercial operation early next year, according to Rosenergoatom, Rosatom’s electric power division.

Majumdar

Arun Majumdar, a professor of mechanical engineering at Stanford University and former vice president for energy at Google, is a leading contender for secretary of energy in a Biden administration, according to a November 12 Bloomberg story.

Chosen on November 10 to lead Biden’s Department of Energy transition team, Majumdar was also the first director of the Advanced Research Projects Agency-–Energy (ARPA-E), serving in that role from 2009 to 2012. Bloomberg quotes Jeff Navin, director of external affairs at TerraPower, as saying, “He had as good relationships with Republicans as he did with Democrats as the first director of ARPA-E, and he took the time to get to know key legislators personally.”

On November 8, less than a week after becoming Belarus’s first nuclear reactor to be connected to the power grid, and only one day after a visit to the Belarusian site from the country’s president, Alexander Lukashenko, to celebrate the accomplishment, Belarusian-1 was forced to cease power production, a report from the Associated Press states.

Xcel Energy’s Prairie Island is the probable location for the nation’s first demonstration of high-temperature steam electrolysis at a nuclear power plant. Idaho National Laboratory, which plays a key role in a hydrogen demonstration project launched last year with Xcel Energy, Energy Harbor, and Arizona Public Service (APS), announced on November 9 that Prairie Island, which houses two 550-MWe pressurized water reactors, would likely be chosen over the one-unit boiling water reactor plant at Monticello.

Minneapolis-based Xcel Energy will work with INL to demonstrate a system that uses the plant’s steam and electricity to split water. The resulting hydrogen will be used at the power plant, but excess hydrogen could be sold to other industries. Hydrogen has applications in transportation and in industrial sectors, including steel and ammonia production.

More than $10 million in federal funding for the Xcel Energy demo was announced by the Department of Energy on October 8. It is just one phase of a project that showcases collaboration between the DOE’s Office of Nuclear Energy and Office of Energy Efficiency and Renewable Energy. Commercial hydrogen production via low-temperature electrolysis is being demonstrated at Energy Harbor’s Davis-Besse plant. APS, which operates the Palo Verde generating station, will build on the Xcel Energy demo to develop an initial design and feasibility assessment for plant modifications to integrate a reversible hydrogen electrolysis system with the plant’s secondary system and will include hydrogen storage infrastructure.

Chatterjee

The Trump administration on November 5 removed Neil Chatterjee from the chairmanship of the Federal Energy Regulatory Commission, replacing him with fellow Republican James Danly, who was confirmed to a seat on the commission in March.

Chatterjee joined FERC in 2017, serving as chairman from August to December 2017. He returned to the leadership role in October 2018, following the departure of Kevin McIntyre. In a tweet, Chatterjee said that he intends to complete his term, which expires in June 2021.

One week after issuing a six-figure civil penalty to the Tennessee Valley Authority for violating Nuclear Regulatory Commission rules involving employee protection, the NRC has proposed penalties totaling more than $900,000 on TVA for a 2015 incident at the utility’s two-unit Watts Bar nuclear plant, located near Spring City, Tenn.

The NRC also has issued violations to two managers and a reactor operator for their roles in the incident.

The enforcement actions are the result of an NRC investigation—initiated in August 2016 and completed in May of last year—into events that occurred during and after the startup of Watts Bar-1 following a maintenance outage in November 2015.
