Rempe

The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards has elected Joy Rempe as chair, Walter Kirchner as vice chair, and David Petti as member-at-large. All three are ANS members.

“I am honored that my colleagues on the ACRS elected me to this position,” said Rempe, of Rempe and Associates. “The leadership team looks forward to ensuring that the ACRS continues its tradition of providing the commission advice on safety issues.”

Bios: Rempe has more than 35 years of experience in the areas of reactor safety and instrumentation performance. Prior to retiring as a Laboratory Fellow at Idaho National Laboratory, she founded an instrumentation development and deployment laboratory, which supported irradiation testing in U.S. and international facilities.

Throughout the history of commercial nuclear power plant operations, there have been events that changed the industry. The incidents at Three Mile Island and Fukushima brought about great advancements in how nuclear plants are operated, including additional safety measures and supplemental training on how to prevent such events. Looking forward, the commercial nuclear industry is poised for a similar transformative change: one motivated by financial viability.

A new website, Milestones in Advanced Nuclear, has been launched by the Department of Energy's Gateway for Accelerated Innovation in Nuclear (GAIN). The website features news stories about advanced reactor activities and offers a “Contact an expert” section for submitting questions and comments for response from GAIN.

The Department of Energy recently announced the establishment of a new office aimed at supporting clean energy technology demonstration projects in areas such as advanced nuclear reactors, clean hydrogen, carbon capture, and grid-scale energy storage.

A creation of the $1.2 trillion infrastructure bill signed into law by President Biden last November, the Office of Clean Energy Demonstrations boasts a $21.5 billion budget, including $2.4 billion for the Advanced Reactor Demonstration Program.

France and other pronuclear European Union members appear to be winning the argument with their antinuclear neighbors—Germany, most prominently—regarding whether to add nuclear energy to the EU taxonomy, the classification system used to direct investments toward environmentally sustainable economic projects.

On January 1, the European Commission released a 60-page draft proposal that includes nuclear and natural gas in the taxonomy. Also, in a related press release, the EC said that it has begun consultations with EU members “on a draft text of a Taxonomy Complementary Delegated Act covering certain gas and nuclear activities.”

The 2021 ANS Winter Meeting included an executive session on advanced reactor licensing, featuring the leaders of four of the top advanced reactor companies: Mike Laufer, chief executive officer of Kairos Power; Jake DeWitte, CEO of Oklo; Simon Irish, CEO of Terrestrial Energy; and Harlan Bowers, president of X-energy.

For well over 30 years, ANS leadership has sparred with members of the academic community about the issue of page charges for ANS’s publications. Page charges have been in place all this time as a way to cover the cost of publication for those journals, as well as to support other beneficial activities of the Society. However, especially in recent years, attitudes among academic publishers have shifted, and page charges for technical journal publications are essentially extinct. ANS’s three technical journals—Nuclear Science and Engineering, Nuclear Technology, and Fusion Science and Technology—have held on to the page charge revenue stream despite vocal criticism from the community.

Until now.

Marzano

Matthew Marzano is beginning a year of service in Washington, D.C., as the 2022 Glenn T. Seaborg Congressional Science and Engineering Fellow, and he is excited about bringing his nuclear power experience to the policy-making process.

“I am most looking forward to the opportunity to learn about the legislative process and the conduct of business on Capitol Hill. Oftentimes we are presented a picture of a dysfunctional Congress through the media, but I’ve gathered through the orientation process and congressional interviews that collaboration is alive and well, especially in the area of clean energy,” Marzano said.

Holding to its Fukushima-inspired policy of phasing out nuclear power, and ignoring pleas from a variety of clean energy advocates to reconsider, Germany has closed three of its remaining six operating nuclear power plants.

The Nuclear Regulatory Commission has proposed a $150,000 fine for apparent security-related violations at the Oyster Creek nuclear power plant in New Jersey. Oyster Creek permanently ceased operations in 2018, and ownership of the plant was transferred to Holtec Decommissioning International for decommissioning in July 2019.

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The October issue focused on plant maintenance and outage management with multiple articles looking at efficient ways to deal with plant maintenance. The article below looks at the herculean effort by INL to lead a full overhaul of the Advanced Test Reactor--a task that happens about every 10 years.

Out of the frenzy of nuclear technology and engineering development at the height of the Atomic Age, a few designs stand out above the rest—designs so innovative that they would not be surpassed for years, or even decades. An example of this unsurpassed design brilliance exists in the form of Idaho National Laboratory’s Advanced Test Reactor.

“ATR is really a beautiful machine,” said Sean O’Kelly, associate lab director for the ATR Complex. “The elegant cloverleaf core and control systems were a stroke of genius that solved just about every key problem of test reactor design. The designers’ solutions to those problems give us a testing capacity and flexibility that have yet to be matched.”

In March 1972, Stephen Hanauer, a technical advisor with the Atomic Energy Commission, met with Norman Rasmussen, a nuclear engineering professor at the Massachusetts Institute of Technology. The AEC had recruited Rasmussen to develop a report, The Reactor Safety Study (WASH-1400), to estimate the probabilities and consequences of a major nuclear power plant accident. With thousands of safety components in a modern reactor, the task was mind-boggling. Rasmussen proposed a novel approach based on more powerful computers, “fault tree” methodology, and an expanding body of operational data. By calculating and aggregating probabilities for innumerable failure chains of components, he believed he could develop a meaningful estimate of overall accident risk. WASH-1400 would be a first-of-its-kind probabilistic risk assessment (PRA).

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The August issue was the annual Vendor/Contractor profile issue, with an additional focus on programs to help the current fleet compete in local energy markets. The article below looks at the Utilities Service Alliance's Advanced Remote Monitoring and Diagnostics Services program.

It is no secret that the nuclear power industry is enduring an economic crisis. Brought about largely by the impact of technological disruption across the larger energy market, a number of utilities have had no option but to prematurely shut down some nuclear plants because they could no longer compete in the regions they serve. Many others are similarly at risk.

The biggest impact of radiation in our lives may come not from radiation itself, but from regulations and guidelines intended to control exposures to man-made sources that represent a small fraction of the natural radiation around us.

Decades of research have been unable to discern clear health impacts from low levels of ionizing radiation, leading to calls for a new research program—one with a strategic research agenda focused on how the scientific understanding of the health effects of low doses (below 100 millisievert) and low dose rates (less than 5 mSv per hour) can best be augmented, applied, and communicated.

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The June issue reviewed some topics in human factors and instrumentation and controls such as the article below that looks at the NRC's review of digital instrumentation systems in the current fleet.

The Nuclear Regulatory Commission^a first formally developed infrastructure for the review of digital instrumentation and control (I&C) systems in the 1990s. Although the current fleet of nuclear power plants in the United States was originally designed and constructed with analog systems, the U.S. nuclear industry has for more than 30 years been working to upgrade these older systems with modern digital equipment.

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The May issue reviewed the economics of nuclear power and provided some great articles on nuclear power plant capacity factors, advanced reactor markets, the economic consequences of plant closures, plant closures as an opportunity for industry engagement with local communities, and the article below that looks at why the electricity markets are failing nuclear power plants.

The Biden administration has a goal to decarbonize the U.S. electricity sector by 2035.¹ Achieving this goal would require a massive nuclear power build program. The U.S. nuclear power industry’s size and historical success signal that we are in a good position to do this, but at present, the U.S. nuclear fleet is shrinking. Why is this so, and what can be done to turn the trend around?

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The April issue reviewed the current state of advanced reactors. This article looks at how the DOE and private industry are working together to realize the benefits of advanced nuclear.

As electric utilities rush to reduce carbon emissions by investing in intermittent renewables such as wind and solar, they often rely heavily on fossil fuels to provide steady baseload power.

More than 60 percent of the nation’s electricity is still generated with fossil fuels, especially coal-fired and gas-fired power plants that have the ability to quickly ramp up or ramp down power to follow loads on the electric grid. Most experts agree that even with a radical advancement in energy storage technology, relying exclusively on wind and solar to replace fossil fuels won’t be enough to maintain a stable electric grid and avoid the major impacts of climate change.

From the time we discovered how the sun produces energy, we have been captivated by the prospect of powering our society using the same principles of nuclear fusion. Fusion energy promises the bounty of electricity we need to live our lives without the pollution inherent in fossil fuels, such as oil, gas, and coal. In addition, fusion energy is free from the stigma that has long plagued nuclear power about the storage and handling of long-lived radioactive waste products, a stigma from which fission power is only just starting to recover in green energy circles.

As a source of carbon-free electricity, nuclear energy currently dominates in the United States. However, the light water reactors in the U.S. are approaching the end of their licensed service lives. Meanwhile, low-cost electricity generated by fossil fuel–based sources (such as natural gas) poses an ongoing challenge to the economic viability of commercial nuclear reactors. To enhance the competitiveness of the nuclear industry, we need to bring down the high operating and maintenance (O&M) costs through savings available from utilizing modern, efficient sensing and automation technologies.

Belgium’s seven-party coalition government this morning announced via press conference a tentative agreement to close the nation’s two nuclear power plants by 2025, confirming a commitment made in October of last year when it took office. Plant closures are scheduled to begin in 2022.
