June 9, 2021, 9:31AMNuclear News

The Nuclear Regulatory Commission announced on June 8 that it has awarded 30 academic grants to 26 academic institutions in 19 states, totaling nearly $10.7 million. The funds will support scholarships, fellowships, and faculty development at four-year universities and colleges, two-year trade schools and community colleges, and minority-serving institutions.

Coolant flow around the fuel pins in a light water reactor core plays a critical role in determining the reactor’s performance. For yet-to-be-built small modular reactors, a thorough understanding of coolant flow will be key to successfully designing, building, and licensing first-of-a-kind reactors.

Oak Ridge National Laboratory has a long record of advancing fusion and fission science and technology. Today, the lab is focused more than ever on taking advantage of that spectrum of nuclear experience to accelerate a viable path to fusion energy and to speed efficient deployment of advanced nuclear technologies to today’s power plants and future fission systems.

The definition of a microreactor is ambiguous. But whether your upper cutoff is 10 MW or 20 MW, the Microreactor Applications Research Validation and Evaluation (MARVEL) reactor that the Department of Energy plans to build is, at 100 kW, on the tiny side of micro.

NRC reports nine abnormal occurrences in FY 2020

June 8, 2021, 6:59AMNuclear News

The Nuclear Regulatory Commission has sent to Congress its annual report on abnormal occurrences involving the medical and industrial uses of radioactive material. An abnormal occurrence is defined by law as an unscheduled incident or event that the NRC determines to be significant from the standpoint of public health or safety. The NRC sets specific criteria, most recently updated in October 2017, for determining which events qualify.

As governments around the world cooperate on the ITER tokamak and, in parallel, race each other and private companies to develop commercial fusion power concepts, it seems that “game-changing” developments are proclaimed almost weekly. Recently, the United Kingdom and China announced new fusion program results.

U.S. and France commit to “common ambition” on advanced nuclear

June 2, 2021, 3:12PMNuclear News

U.S. energy secretary Jennifer Granholm and French minister for the ecological transition Barbara Pompili issued a joint statement on May 28 in which they pledged to work together to meet shared climate goals.

“France and the United States share common goals and common resolve in fighting climate change and working toward reaching the ambitious target set forth by the Paris agreement,” the statement read. “We are united in a common ambition on both sides of the Atlantic: achieving net-zero carbon emissions by 2050. Reaching this common objective will require leveraging all currently existing emission-free technologies available to us while simultaneously intensifying research, development, and deployment across a suite of zero-emissions energy sources and systems. Ensuring that these energy systems are efficient and reliable, integrating larger shares of renewables coupled with nuclear energy, which is a significant part of today’s electricity production in both our countries, will be crucial to accelerate energy transitions. Reaching this common objective will also require a wide variety of favorable financing conditions across the range of zero-emitting power sources and systems.”

Clinical trial funding to expand the radioisotope medicine chest

The Department of Energy is providing up to $2 million in fiscal year 2022 to fund university and national laboratory studies into the use of novel, medically relevant isotopes for use in pre-clinical and clinical medical trials, the DOE’s Office of Science announced on June 1.

“Now is the time” for more ATR capacity: A conversation with Lightbridge

Operators at the Advanced Test Reactor at Idaho National Laboratory have begun a nine-month outage to perform a core internals changeout. When the ATR is restarted in early 2022, the top head closure plate of the pressurized water test reactor will have new access points that could permit the irradiation of more fuel and material samples in the reactor’s high-flux neutron conditions.

Nine-month outage preps ATR for years of continued operation

The Advanced Test Reactor (ATR) at Idaho National Laboratory is getting an overhaul that will keep it off line for nine months. When the ATR is restarted in early 2022, the one-of-a-kind pressurized water test reactor—which is operated at low pressures and temperatures as a neutron source—will be ready for another decade or more of service, with the potential for more experimental capacity in years to come.

The International Atomic Energy Agency has created a new program, NUclear TEChnology for Controlling Plastic Pollution (NUTEC Plastics), to address the global environmental impact of plastic pollution in oceans. It uses nuclear technology to monitor pollution and also to decrease the volume of plastic waste by using irradiation to complement traditional plastic recycling methods.

Pebble bed reactors, friction, and cooling

May 25, 2021, 9:31AMANS Nuclear CafeLaura Simmons

When one of the largest modern earthquakes struck Japan on March 11, 2011, the nuclear reactors at the Fukushima Daiichi nuclear power plant automatically shut down as designed. The emergency systems, which would have helped maintain the necessary cooling of the core, were destroyed by the subsequent tsunami. Because the reactor could no longer cool itself, the core overheated, resulting in a severe nuclear meltdown.

Since then, reactors have improved exponentially in terms of safety, sustainability and efficiency. Unlike the light-water reactors at Fukushima, which had liquid coolant and uranium fuel, advanced reactors have a variety of coolant options, including molten-salt mixtures, supercritical water, and gases such as helium.

The Department of Energy has announced up to $40 million in funding for a new Advanced Research Projects Agency-Energy (ARPA-E) program to conduct research and development into technologies for reprocessing and ultimately disposing of used nuclear fuel. The program, “Optimizing Nuclear Waste and Advanced Reactor Disposal Systems” (ONWARDS), announced on May 19, targets both open (once-through) and closed (reprocessing) fuel cycles to reduce the amount of waste produced from advanced reactors tenfold when compared to light water reactors.
