The November 17 session titled “Preview of NPIC&HMIT 2021” was sponsored by the Human Factors, Instrumentation and Controls Division. The session was chaired by Pradeep Ramuhalli, of Oak Ridge National Laboratory, and featured four panelists: Ronald L. Boring, of Idaho National Laboratory; Jamie B. Coble, of the University of Tennessee at Knoxville; Raymond L. Herb, of Southern Nuclear Operating Company; and Hyun Gook Kang, of Rensselaer Polytechnic Institute.

The panelists provided a preview of trends in I&C and human factors that are likely to be featured at the 12th ANS Topical Meeting on Nuclear Plant Instrumentation and Control and Human-Machine Interface Technology Conference (NPIC&HMIT), which will be held in conjunction with the 2021 ANS Annual Meeting in Providence, R.I., in June. Ramuhalli said that the paper submission process has begun. The NPIC&HMIT 2021 call for papers is available online.

Herb

The industry perspective: Herb, who works on digital modernization for Southern Nuclear’s reactor fleet, reflected on working early in his career with equipment that required daily calibration by I&C techs. “Operators running around the panels, checking here, checking there,” he said. “Now, I see a calm control room for operators at Vogtle-3 and -4 who can operate everything from one chair.”

Herb added that he is not a human factors expert. “All I can do is communicate the needs of the U.S. nuclear industry from my perspective,” he said. Among those needs are realistic task analysis and effective change management. While the U.S. fleet’s original analog control systems were “biased toward ‘no change,’” he said, Southern’s current fleet strategy “is incremental change with every design we put in, to shepherd our existing fleet to something that is closer to Vogtle-3 and -4.”

Boring

New modalities: Boring offered his take on what’s next for human factors. He pointed out that NPIC&HMIT 2019 had four sessions on validation, and that validation is critical because new digital control rooms need to be proven. “Many of our current fleet have had the same control rooms for 40 years,” he said. “We can’t hope to have a digital control room for 40 years—we have to support evolution over time.” He predicted that NPIC&HMIT 2021 will see an emphasis on validation and interaction modalities for new plants, such as microreactors and small modular reactors, including automation.

Coble

University support for data analytics: Coble talked about improving nuclear power economics through data-driven decision-making. Operating plants are being shut down, she said, and a big part of the problem is operating and maintenance costs. “How can we make nuclear more economical?” she asked. “The current approach of frequent equipment monitoring works to keep equipment reliability up but does not help with costs.”

Coble said that there is a need for development in sensors and in models and algorithms that mine large data sets. University research and training can help solve identified problems, she said, but while there is a well-developed data set on light-water reactors, equivalent data is not yet available for advanced reactors that operate differently, making it more difficult to set a risk-informed approach.

Kang

New topics: Kang took attendees on a deep dive into the topics that were presented at NPIC-HMIT 2019 and made some predictions for 2021. Control platforms and status identification and decision-making were well represented in 2019, as were newer topics of cybersecurity and wireless communications. In 2019, Kang said, “Operation automation was discussed, but ‘autonomous operation’ was not discussed yet. . . . I expect we will have more papers regarding this issue in the coming conference.”

That is just one of several topics Kang expects to see at the 2021 meeting, because, he said, I&C is a fast-moving area.

Other anticipated topics include the decision-making process between machine learning applications and human operators and practical cybersecurity solutions.

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.”

Russian company Atommash has delivered the reactor pressure vessel for Unit 1 of the Akkuyu plant, the nuclear power facility under construction in Turkey, Akkuyu Nuclear JSC announced recently.

Atommash is a branch of AEM Technologies, which is part of Atomenergomash, the equipment-building division of Rosatom, Russia’s state atomic energy corporation. Akkuyu Nuclear, based in Ankara, was established to implement the Russian-Turkish project.

It took some three years to manufacture the 330-metric ton, 12-meter-long reactor pressure vessel and 20 days to transport it from the Atommash plant in Volgodonsk, Russia, to the eastern cargo terminal at the Akkuyu plant site, according to Akkuyu Nuclear.

The General Chair’s Special Session of the 2020 ANS Virtual Winter Meeting was held on November 17. Moderated by Paul Kearns, director of Argonne National Laboratory, and Bryan Hanson, executive vice president and chief generation officer of Exelon Nuclear, the session, titled “Nuclear Science and Industry: The next transformation,” featured a panel of science and industry experts discussing how innovation is transforming both the current fleet of reactors and preparing for a future with advanced reactors, integrated systems, and smarter grids.

In addition to the session’s respected panel members, the Zoom meeting included appearances from some top names in nuclear, including Holtec International’s Kris Singh, Sama Bilbao y Leon of the World Nuclear Association, Warren Miller, Jr. from Kairos Power and Texas A&M University, Terrestrial Energy’s David Hill, and many more. In a short, prerecorded video, these experts discussed many of the issues facing the nuclear industry today, which were then expounded upon by the panel members.

The 2020 ANS Virtual Winter Meeting opened on November 16 with a plenary session moderated by ANS President Mary Lou Dunzik-Gougar and more than 700 people in attendance. The opening plenary session was followed by nearly 40 panel and technical sessions. Recordings of all the sessions are posted on the meeting platform and can be view by all registered attendees at any time.

Two sessions held in the afternoon of opening day were centered around the 50th anniversary of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Both sessions featured distinguished experts on the NPT to discuss its successes, challenges, future, and the role of the United States in international nonproliferation.

The Department of Energy released a Hydrogen Program Plan on November 12 that provides a strategic framework for the agency’s hydrogen research, development, and demonstration activities.

The DOE’s Offices of Nuclear Energy, Energy Efficiency and Renewable Energy, Fossil Energy, Electricity, and Science, and the Advanced Research Projects Agency–Energy are all working on the production, transport, storage, and use of hydrogen in several sectors of the economy and have developed technical and programmatic multi-year plans. The Hydrogen Program Plan coordinates and complements those efforts by presenting a strategic direction that highlights the importance of collaboration both within DOE and with stakeholders in industry, academia, and the states.

Presented as an embedded topical meeting at the 2020 ANS Virtual Winter Meeting, the Technology of Fusion Energy (TOFE) 2020 meeting opened on November 16 with the first of four plenary sessions to be held during the week: “Looking Back and Looking Forward in Fusion.” (TOFE 2020 also features 29 technical sessions through November 19.)

The plenary session, chaired by Savannah River National Laboratory’s Greg Staack, featured two speakers: Melissa Hanson, curator for the Savannah River Site Cold War Historic Preservation Program, and Heather Lewtas, a technical lead for the United Kingdom Atomic Energy Authority (UKAEA)’s Spherical Tokamak for Energy Production program.

The 2020 ANS Virtual Winter Meeting kicked off on Monday, November 16, with an opening plenary moderated by ANS President Mary Lou Dunzik-Gougar. The session, delivered via Zoom, featured two keynote speakers—Alex Epstein of the Center for Industrial Progress and Jessica Lovering of the Good Energy Collective.

Chosen with deliberation, the two speakers represented two very different political and philosophical views of energy production, but each made the case why nuclear is the best choice for a better world.

The Monday session “Advancement in Medical Isotopes Production and Applications” of the 2020 ANS Virtual Winter Meeting was sponsored by the Isotopes & Radiation Division and co-chaired by Lin-Wen Hu of Massachusetts Institute of Technology and James Bowen of Pacific Northwest National Laboratory.

Radioisotopes produced from nuclear reactors and accelerators are widely used for medical diagnostics and cancer therapy. Technetium-99m (decay product of molybdenum-99), for example, is used in more than 80 percent of nuclear medicine diagnostic procedures. The session featured speakers who discussed the advancement and status of domestic production and applications of medical isotopes.

The "Hybrid and Integrated Energy Systems" session on Monday during the ANS 2020 Virtual Winter Meeting was sponsored by the Operations and Power Division and chaired by Piyush Sabharwall of Idaho National Laboratory.

Oak Ridge National Laboratory scientists have developed a method to produce solid yttrium hydride for use as a moderator for the Transformational Challenge Reactor (TCR), a 3-MWt additively manufactured microreactor that ORNL aims to demonstrate by 2023. Lacking a commercial supply of the metal hydride, ORNL scientists developed a system to produce yttrium hydride in large quantities and to exacting standards.

The hydrogen density and moderating efficiency of metal hydrides—which combine a rare earth metal with hydrogen—could enable smaller reactor cores that can operate more efficiently and reduce waste products, according to ORNL. The material could be used in other advanced reactor designs, including space power and propulsion systems for NASA, and has been proposed as a shield component for thermalization and neutron absorption in fast-spectrum nuclear reactors.

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.

In an MIT News article playfully titled “No matter the size of a nuclear party, some protons and neutrons will always pair up and dance,” author Jennifer Chu explains that findings on the interactions of protons and neutrons recently published in the journal Nature Physics show that the nucleons may behave like atoms in a gas.

A Massachusetts Institute of Technology–led team simulated the behavior of nucleons in several types of atomic nuclei using supercomputers at Los Alamos National Laboratory and Argonne National Laboratory. The team investigated a range of nuclear interaction models and found that formulas describing a concept known as contact formalism can be generalized to predict how protons and neutrons interact at close range.

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.

BWX Technologies Inc. announced on November 10 that its BWXT Nuclear Operations Group Inc. (BWXT NOG) subsidiary has completed its TRISO nuclear fuel line restart project and is actively producing fuel at its Lynchburg, Va., facility.

With the restart, BWXT now manufactures fuel across four commercial and government business lines, the company said. In addition to the TRISO line, BWXT operates fuel production lines at BWXT Nuclear Energy Canada, manufacturer of approximately half of the fuel powering the commercial reactor fleet in Ontario, Canada; BWXT subsidiary Nuclear Fuel Services, sole provider of nuclear fuel for the U.S. Navy; and BWXT’s Uranium Processing and Research Reactors operation, the only North American supplier of research reactor fuel elements for colleges, universities, and national laboratories.

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.
