Grossi

The ongoing, tense situation surrounding the Zaporizhzhia nuclear power plant in Ukraine was the subject of a recent interview with International Atomic Energy Agency director general Rafael Mariano Grossi when he appeared on CBS's 60 Minutes program.

The Zaporizhzhia facility is in an area of Ukraine that became occupied by Russian forces in late February 2022. Though Ukrainian staff remain at the now mostly idle plant, artillery shells have repeatedly landed at and near the plant over the past several months, with Ukrainian officials—along with many Western media outlets—blaming Russia, while Russian officials and media blame Ukraine.

Action from the IAEA: Following months of negotiations with both sides, inspectors from the IAEA, led by Grossi, finally visited the site in late August and early September, and the agency has been monitoring the situation since then with an observation mission at the site. In the interview, which aired on November 20, Grossi did not attribute blame for the shelling to either side.

Advancing its efforts to develop the Arctic and establish new energy markets, Russia launched a new nuclear-powered icebreaker, the Yakutia, in St. Petersburg during a November 22 ceremony. At the launching in the northern Russian port city, the Russian flag was raised on another nuclear icebreaker, the Ural. Overseeing the events via video link from the Kremlin, Russian president Vladimir Putin said that the icebreakers “were laid down as part of a large serial project and are part of our large-scale, systematic work to reequip and replenish the domestic icebreaker fleet, to strengthen Russia's status as a great Arctic power.”

Nuclear fusion “might actually be on the cusp of commercial viability” today, says a recent article in Fortune magazine. The article offers a brief review of recent technical and entrepreneurial developments in fusion energy. It also places these developments in perspective regarding the hurdles that remain before commercialization can be realized.

A study recently published in Nature Communications brings a new perspective on how radiation travels through dense plasmas, potentially leading to a better understanding of the evolution of stars and the development of controlled nuclear fusion reactions. Researchers led by investigators at the University of Rochester Laboratory for Laser Energetics (LLE) achieved their findings by conducting experiments with LLE’s OMEGA laser system. This extensive system, which is 19 meters tall and 70 meters long, consists of 60 laser beams that can focus as much as 30,000 joules of energy onto a target for the study of nuclear and fluid dynamic events.

The Japan Nuclear Safety Institute (JANSI) marked its 10th anniversary on November 15 by publishing a letter that highlighted some of the organization’s greatest accomplishments of the past decade. In the letter, William Edward Webster Jr., chairman of the JANSI board of directors, and Hiromi Yamazaki, JANSI president and chief executive officer, expressed their “sincere gratitude to all our members and other stakeholders who have provided support and guidance over the past 10 years.”

The Nuclear Regulatory Commission has conducted a special inspection at the University of Texas’s TRIGA Mark II nuclear research reactor in Austin to evaluate the use of improper fuel. The inspection was ordered following a notification from the University of Texas—Austin to the NRC that the research reactor had been operating for several months with two fuel elements that were not licensed for the reactor.

The Nuclear Regulatory Commission has announced that it will review a construction permit submitted by the Nuclear Energy eXperimental Testing (NEXT) Laboratory at Abilene Christian University for the lab’s planned molten salt research reactor (MSRR). The NRC informed Rusty Towell, director of the NEXT Lab and professor in ACU’s Department of Engineering and Physics, about its acceptance of the construction permit review in a November 18 letter. The NEXT Lab had submitted the construction permit application on August 15; it was the first-ever university application for an advanced research reactor. On October 14, they provided the NRC with additional information about instrumentation and controls. (Nuclear News featured an article about the NEXT Lab and the MSRR in the November issue.)

Nuclear energy “has exceptional characteristics that make it uniquely qualified to address all three facets of the energy trilemma: affordability, sustainability, and reliability,” according to a new report, Solving the Energy Trilemma: The Case for Nuclear as a Sustainable Investment. Developed by the Center for ESG and Sustainability (CESG), which has a partnership with Columbia University’s International Research Institute for Climate and Society, the report concludes, “Even absent ESG [environmental, social, and governance] considerations, nuclear is an investible asset. However, its strong ESG performance makes the case for investment even stronger.”

The Cabell Huntington Hospital system, based in Huntington, W.V., has begun implementing corrective actions associated with nuclear medicine activities, in line with a settlement agreement reached with the Nuclear Regulatory Commission. The agreement stems from NRC inspections at the hospital’s facilities that uncovered 14 violations, described in a June 2022 NRC inspection report. As a result of the hospital taking corrective action, the NRC will not impose civil penalties.

The U.S.-Japan Nuclear Security Working Group (NSWG) convened for its 11th meeting in early November in Tokyo. The group continued its efforts, begun in 2011, to strengthen global nuclear security and enhance international cooperation in peaceful nuclear activities. The meeting was originally scheduled for 2020 but was postponed because of restrictions related to the COVID-19 pandemic.

NBC Chicago featured a story last week about a visit to the Windy City by the commander and crew of the USS Hyman G. Rickover (SSN-795), the navy’s newest nuclear submarine. The submarine was christened in July 2021 and is currently undergoing trials out of Naval Submarine Base New London in Groton, Conn., before its expected commissioning in 2023. Reporter Charlie Wojciechowski described the sailors’ meetings with students from Chicago’s Rickover Naval Academy, along with the sailors’ visits to the Museum of Science and Industry and other city landmarks. He also interviewed Commander Matthew H. Beach.

The University of Tennessee–Knoxville Department of Nuclear Engineering hosted the inaugural Nuclear Engineering Department Heads Organization (NEDHO) Diversity Panel on October 27. The panel featured three African American speakers who discussed overcoming challenges in their engineering education and careers to find success. A common theme that emerged from the conversation was that, in addition to their own determination to succeed, all the panelists benefited from caring adult guidance during their youth, as well as from strong support from friends, family, and colleagues as they pursued their goals.

The authors of a study that was recently published in Advances in Agriculture have recommended that the plant Sesuvium portulacastrum, commonly known as sea purslane, “be cultivated in [cesium]-contaminated soils and near nuclear power plants for phytoremediation.” The researchers found that S. portulacastrum is a “hyper-accumulator” of radioactive cesium isotopes, which are byproducts of nuclear fission reactions in nuclear reactors. The study results suggested that these plants could efficiently remove the toxic metallic chemicals from contaminated soil around nuclear facilities.

The Nuclear Regulatory Commission is increasing its social media presence with its new Instagram page, the agency announced. The "nrcgov” account on the popular site will post photos, short videos, and graphics to add “a more creative approach to information regarding the NRC’s mission, with a focus on the skilled and diverse employees who carry it out.”
