Motivated by February’s Texas grid debacle and last month’s Electric Reliability Council of Texas (ERCOT) alert pleading with residents to conserve energy, Gov. Greg Abbott earlier this week issued a letter to members of the Public Utility Commission of Texas (PUC), directing them to take immediate action to improve electric reliability across the state. According to the governor’s office, the directives build on reforms passed in the 87th legislative session to increase power generation capacity and ensure the reliability of the Texas power grid.

The U.S. Department of Energy has announced $5.8 million in funding to develop three construction technologies that together can reduce the cost of new nuclear builds by more than 10 percent.

Two reports submitted last week to the European Commission to help it decide whether to include nuclear energy in the “EU taxonomy”—a classification system establishing a list of environmentally sustainable economic activities for the European Union—could end up prolonging the decision-making process, as the reports are not in full agreement on the matter.

The Department of Energy’s Office of Science has named seven companies as the recipients of cost-shared funding granted through the Innovation Network for Fusion Energy (INFUSE). A total of $2.1 million in first-round fiscal year 2021 funding was awarded on July 1 across nine collaborative projects between DOE national laboratories and private industry aimed at overcoming challenges in fusion energy development.

Six decades after the launch of the first nuclear-powered space mission, Transit IV-A, NASA is embarking on a bold future of human exploration and scientific discovery. This future builds on a proud history of safely launching and operating nuclear-powered missions in space.

Egypt’s Nuclear Power Plants Authority (NPPA) has applied to the Egyptian Nuclear and Radiological Regulation Authority (ENRRA) for a construction permit to begin building the first two of four proposed Russian-designed and -supplied reactors at Egypt’s El Dabaa site.

The Nuclear Regulatory Commission has halted efforts to consider allowing U.S. nuclear power plant owners to request 40-year license renewals for their facilities, the agency announced on Facebook and Twitter on July 2. Currently, the maximum potential operating lifespan for a plant is 80 years: 40 years with the original license, 20 more with an initial license renewal, and another 20 with a second renewal.

The Nuclear Regulatory Commission is seeking comments on a proposed rule that would certify NuScale Power’s small modular reactor design for use in the United States. Notice of the proposed rule was published in yesterday’s Federal Register.

Seventy-five years ago today, on July 1, 1946, the first U.S. national laboratory was chartered with the singular mission of developing the peaceful uses of nuclear energy. Now, the Department of Energy’s Argonne National Laboratory is one of the nation’s largest science laboratories, working on diverse challenges in energy, climate, science, medicine, and national security.

As indicated in the April issue of Nuclear News, development of advanced reactor concepts heavily emphasizes small modular reactors and microreactors. Promised features, such as capital cost savings, plant system simplification, implementation flexibility, and favorable operational responsiveness with passive safety behavior, all promote small reactors as desirable, non-­­carbon-­­emitting power sources to help satisfy future energy needs. In spite of the favorable up-­­front economics compared to large nuclear reactors, SMRs and microreactors do not provide the benefit of economy of scale that typically compensates for the high staffing demands associated with traditional, labor-intensive operations and maintenance (O&M) practices in the nuclear industry. To avoid the prospect that high staffing levels relative to unit power production will lead to unsustainable O&M costs for small reactors, a significantly higher degree of automation, to the point of near autonomy, is necessary. Essentially, the economy of automation is needed to offset the loss of economy of scale.

Électricité de France has signed a letter of intent with the Emirates Nuclear Energy Corporation to develop a memorandum of understanding for cooperation on research and development in the nuclear energy sector.

Work on the third phase of the multi-reactor project at India’s Kudankulam nuclear power plant formally commenced earlier this week with the first pouring of concrete into the foundation plate of the Unit 5 reactor building.

The U.S. state with more nuclear power plants than any other—Illinois—has no operating university research reactors. A team at the University of Illinois at Urbana-Champaign (UIUC) intends to reverse that situation and construct a high-temperature gas-cooled microreactor. If the team's plans go ahead, the first new U.S. university research reactor deployment in about 30 years could also support commercial advanced reactor deployment.

New Jersey’s Public Service Enterprise Group has announced its intention to achieve net-zero emissions by 2030, shaving two decades off its previously announced target date of 2050. PSEG is owner of the Hope Creek nuclear plant and is co-owner, with Exelon, of the Salem plant.

Romania has ratified a draft intergovernmental agreement signed in 2020 with the United States on cooperation in the field of nuclear energy. Initialed last October by Romania’s energy minister, Virgil Popescu, and the then U.S. energy secretary Dan Brouillette, the agreement, reportedly worth some $8 billion, calls for cooperation on completing the construction of Units 3 and 4 at Romania’s Cernavoda nuclear power plant, as well as the refurbishment of Unit 1. The European Commission gave its nod to the agreement last November.

California-based Oklo has received a $2 million cost-share award from the Department of Energy for the commercialization of advanced fuel recycling capabilities by using electrorefining technology. Oklo is matching $1 million in funds and is partnering with the DOE and Argonne National Laboratory on this public-private partnership, which is intended to help reduce fuel costs for advanced reactor designs while reducing waste by turning used fuel into advanced reactor fuel.

Pascrell

Companion bills that call for amending the Internal Revenue Code to establish a tax credit to help existing merchant nuclear plants continue operations debuted on Capitol Hill last week.

In the House on June 21, Rep. Bill Pascrell (D., N.J.) introduced the bipartisan H.R. 4024, dubbed the Zero-Emission Nuclear Power Production Credit Act of 2021. Cosponsors of the legislation include Reps. Brian Fitzpatrick (R., Pa.), Tom Suozzi (D., N.Y.), John Katko (R., N.Y.), Danny Davis (D., Ill.), Anthony Brown (D., Md.), Dutch Ruppersberger (D., Md.), Cheri Bustos (D., Ill.), Mike Doyle (D., Pa.), and Bobby Rush (D., Ill.).

And on June 24, Sen. Ben Cardin (D., Md.) introduced the Senate’s version, S. 2291, with Sens. Joe Manchin (D., W.Va.), Tom Carper (D., Del.), Sheldon Whitehouse (D., R.I.), and Cory Booker (D., N.J.) joining as cosponsors.

The International Atomic Energy Agency last week released its annual nuclear power status data, collected by the Power Reactor Information System (PRIS), the agency’s publicly available nuclear power database.

According to the IAEA’s data summary, nuclear power in 2020 played an important role as an adaptable and reliable supplier of electricity during the pandemic.

Researchers at the Department of Energy’s Princeton Plasma Physics Laboratory are using machine learning to predict electron density and pressure profile shapes on the National Spherical Torus Experiment-Upgrade (NSTX-U), the flagship fusion facility at PPPL that is currently under repair.

The hope is that such predictions, generated by artificial neural networks, could improve the ability of NSTX-U researchers to optimize the components of experiments that heat and shape the fusion plasma.

“This is a step toward what we should do to optimize the actuators,” said PPPL physicist Dan Boyer, author of the paper, “Prediction of electron density and pressure profile shapes on NSTX-U using neural networks,” published by Nuclear Fusion, a journal of the International Atomic Energy Agency. “Machine learning can turn historical data into a simple model that we can evaluate quickly enough to make decisions in the control room or even in real time during an experiment.”
