Tennessee Gov. Bill Lee has announced appointments to his Tennessee Nuclear Energy Advisory Council, established recently via executive order to help position the Volunteer State as a national leader in nuclear innovation.

The nuclear power disconnect in climate finance taxonomies

July 17, 2023, 7:00AMNuclear News

The European Union agreed in July 2022 to include nuclear power in its taxonomy of environmentally sustainable economic activities. Yet as Columbia University senior research scholar Matt Bowen and research assistant Kat Guanio note in commentary published July 6 by Columbia University’s Center on Global Energy Policy, that policy decision remains “a bit of an outlier.” Despite nuclear energy’s anticipated role in achieving decarbonization, many climate finance taxonomies either explicitly exclude nuclear power or are discouragingly ambiguous.

Breakthrough development in aging management of I&C cables

As nuclear power plants in the United States and around the world go through license renewals to operate for up to 60 and 80 years and beyond, aging management of electrical cables takes center stage. Each nuclear power plant unit has thousands of miles of cables, many of which are critical to plant safety and reliability. The most important cables—those in safety systems or safety-related applications—are qualified according to industry standards and guidance documents for nuclear applications. These qualification methods use accelerated aging to simulate cable degradation under natural aging conditions and then subject the cable to a design-basis event simulation to establish the cable’s “qualified life.” This approach has worked well for the length of the initial plant license, but now, many cables are approaching or already are past their 40-year qualified lifespan. With license renewals allowing plants to operate beyond their original design life, the industry has undertaken a variety of research endeavors to help assess the condition of cables as they age and develop in situ testing techniques to verify that cables can continue to operate safely and reliably. For example, in 2022, we completed a multiyear project to develop aging acceptance criteria for a wide variety of condition monitoring techniques that can objectively assess the aged condition of cables while they remain installed in nuclear plants.

Renewed effort on Radiation Exposure Compensation Act

July 14, 2023, 12:01PMNuclear News

Crapo

Bipartisan legislation has been reintroduced in Congress to strengthen the Radiation Exposure Compensation Act (RECA), improving compensation for people who were exposed to radiation as a result of working in uranium mines or living near sites of nuclear weapons testing during the Cold War. The legislation was introduced recently in the Senate by Sens. Mike Crapo (R., Idaho) and Ben Ray Luján (D., N.M.) and in the House by Rep. Teresa Leger Fernández (D., N.M.) and Del. James Moylan (R., Guam).

Follow-up bill: Originally introduced by Crapo in 2021, S. 2798 was put forward again to follow up on the success that Crapo, Luján, and Fernández had last year in extending the RECA program into 2024. The reintroduced bill, which added Moylan as a sponsor, would extend the program further to cover more communities with former uranium workers and “downwinders” (people who were exposed to radiation because they lived downwind from weapons testing sites). While the original legislation covered people in parts of Utah, Nevada, and Arizona, the bill will now also cover those who lived in Idaho, Colorado, New Mexico, and Guam.

Commonwealth Fusion Systems (CFS) and Tokamak Energy Inc. are the two magnetic confinement tokamak fusion developers to receive a portion of the $46 million in funding announced by the Department of Energy in late May for the first 18 months of a public-private Milestone-Based Fusion Development Program aimed at developing fusion pilot plant designs and resolving related scientific and technological challenges within five to 10 years.

Using intelligent technologies to power our present and develop our future

The nuclear power industry has the opportunity for significant advancements in the coming years, driven by the digital integration of instrumentation and controls (I&C), machine learning (ML), artificial intelligence (AI), and optimized operations and maintenance (O&M) technologies. These developments are the enabling technologies that can ensure the efficiency, safety, and reliability of our future fleet of nuclear power plants, propelling the industry toward a more sustainable and intelligent future.

I&C plays a vital role in monitoring and controlling various aspects of nuclear power plants. Traditional I&C systems have relied on hardwired control circuits, but modern advancements are shifting towards digital I&C systems, also known as digital control systems (DCS). These systems offer enhanced flexibility, scalability, and reliability. They utilize advanced sensors, data acquisition systems, and distributed control algorithms to enable real-time monitoring, fault detection, and control optimization.

ADVANCED REACTOR MARKETPLACE

Paragon to supply I&C for Xe-100 SMR

Paragon Energy Solutions and X-energy Reactor Company have entered into a preferred supplier agreement by which Paragon will be the exclusive worldwide supplier for three crucial instrumentation and control systems for X-energy’s Xe-100 advanced small modular reactors: the reactor protection system, post-event monitoring system, and neutron instrumentation system. The new agreement builds on an existing partnership between the two companies in the areas of critical safety mechanisms, which also includes Paragon’s HIPS FPGA system.

There are two open positions on the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS). To fill these positions, the NRC is looking for candidates who have extensive experience in nuclear reactor safety issues—especially in the engineering and safety aspects of new light water and non–light water reactor designs and technologies, or in similar areas of nuclear reactor and fuel cycle safety.

If we’re in a new nuclear renaissance, its capital would appear to be Ontario. On July 7, just two days after debuting a collaboration with Bruce Power to build up to 4.8 GW of new nuclear generation at the Bruce plant, the government of Ontario announced that it is working with Ontario Power Generation to begin planning and licensing for the deployment of three additional GE Hitachi Nuclear Energy (GEH) BWRX-300 small modular reactors at that utility’s Darlington site.

Looking back and looking ahead

It is a great time to be American Nuclear Society president. There are very positive articles in Nuclear News and other places on the advances in fusion, nuclear in space, isotopes, and new power plants. It seems that every month the good news keeps building. I am also fortunate to start my presidency after the extraordinary efforts of past presidents Steve Nesbit (2021–2022) and Steven Arndt (2022–2023).

Steve Nesbit created a special committee to make recommendations on the framework of a generic standard for a high-level radioactive waste repository. The excellent work is currently out for review and, once complete, this standard will be a significant step forward for existing and future reactors. When Steven Arndt started as ANS president last year, he said he would prioritize participation and advocacy, and in these regards he has been an outstanding nuclear advocate. He has taken advantage of being able to travel and has attended numerous conferences in person after the past few years of cancelations, postponements, and virtual meetings for ANS and other industry events. At the same time, Arndt has advocated for a Nuclear Worker Certification program. While the program is not yet approved, I believe it is an excellent initiative, particularly now, with so many people coming to the industry who are new to nuclear—and the growing need for more.

“It is critical after the Hamaoka Nuclear Power Station restart that we reduce our cost and increase our capacity factor while becoming more economically competitive.” Ichiro Ihara, chief nuclear officer of Chubu Electric Power, made this observation recently when the Electric Power Research Institute visited the Japanese nuclear power plant for a strategy development session for plant modernization. EPRI’s team of five specialists spent four days at Hamaoka to investigate the feasibility of potential improvements—the third step of the EPRI modernization strategy planning process. It was a trip six months in the making—and the first time EPRI has applied its nuclear plant modernization process outside the United States.
