Machine learning and environmental remediation

January 28, 2022, 9:29AMANS Nuclear CafeAndrew Amann

Due to the large amount of water used by nuclear power plants, measuring the water’s impact on the environment is a huge data processing task. It is impossible to manually measure millions of gallons, along with tracking wildlife and the weather. The data computation needed to understand environmental patterns takes massive amounts of storage and strong algorithms to uncover anomalies.

The ANS Fuel Cycle and Waste Management Division will present a webinar today at noon EST (the recording will be available via the webinar archive to all ANS members) featuring an international panel of experts on nuclear waste reprocessing. The panel will explore the idea of separating certain radionuclides from waste using recycling technology that enables pure materials to be used for other purposes.

Tennessee governor backs nuclear energy and TVA's plans for SMRs

January 25, 2022, 3:00PMANS Nuclear Cafe

During a tour last week of the Tennessee Valley Authority’s two-unit Watts Bar nuclear power plant in Tennessee, Gov. Bill Lee said, "Nuclear energy is so important not only because it is an important part of TVA's power generation but also because of the value that clean energy via nuclear energy can have for sustainability in this country,” according to an article in the Chattanooga Times Free Press.

Lee added that he would support TVA’s plans if it decided to build small modular reactors.

A new bill in the Indiana state Senate creates guidelines for state regulators to consider small modular reactors should utilities want to build them. Senate Bill 271 was sponsored by Sen. Eric Koch (R., Bedford), chair of the Senate Utilities Committee, and Sen. Blake Doriot (R., Goshen). Supporters of the bill said that SMRs could replace retiring coal plants and would supplement renewables.

The Indy Star reported on January 24 that the utilities committee passed the bill by a vote of eight to two and that it now heads to the full Senate.

In this first installment of a #ThrowbackThursday post, Nuclear News provides a review of radioisotope-powered pacemakers in response to an article in The Wall Street Journal. The article, published earlier this week, looks at the issue of disposing of nuclear-powered pacemakers, although considering how few are still in use today, it seems like this is really much ado about nothing.

Manchin supports nuclear provisions in Biden’s Build Back Better plan

January 14, 2022, 3:25PMANS Nuclear Cafe

Sen. Joe Manchin (D., W.Va.) has been in the news over the past week—and that’s good news for the nuclear community. Last week, The Hill reported on Manchin’s support for climate action, and according to Bloomberg News this week, Manchin is “big on nuclear” and supports the tax credits for nuclear power plants included in the administration’s Build Back Better plan.

Idaho National Laboratory researchers have, for the first time, used a novel technique using high-energy photons to produce scandium-47 from the element vanadium. The project is a collaboration with Jon Stoner and John Longley from Idaho State University’s Idaho Accelerator Center and Tara Mastren from the University of Utah. The results are published in the journal Applied Radiation and Isotopes.

Jimmy Carter is trending on Twitter this week because of his ties to nuclear power. Carter, the 39th president of the United States, was a member of Rickover’s nuclear navy about 70 years ago when he was assigned to help in the aftermath of an accident at the Chalk River Laboratory in Ontario, Canada.

Getting INL to net-zero carbon emissions by 2031

Kandasamy

Daunting tasks are nothing new for Jhansi Kandasamy. Her record of accomplishments over three decades suggests that she is often the first to succeed where others fall short. “I like to be the first,” she said with a laugh.

Her latest first? Kandasamy was recently named Idaho National Laboratory’s net-zero director. She is charged with achieving net-zero carbon emissions for INL within the next 10 years and her plan is to be 75 percent toward that goal within the next five years.

John Wagner, INL director, announced the Net-Zero initiative on Earth Day 2021, and he acknowledged it won’t be easy. “I understand this is an audacious goal,” he said, “but overcoming significant national challenges is exactly what national laboratories were established to do.”

At Senate hearing, Markey attacks, Hanson defends

Markey

At an otherwise congenial Nuclear Regulatory Commission oversight hearing held last week by the Senate Environment and Public Works Committee, Sen. Ed Markey (D., Mass.) made clear his strong disagreement with the agency’s November 3 decision to approve a proposed rule amending regulations for nuclear plants undergoing decommissioning.

“I fear the NRC now stands for Not Recognizing Concerns,” Markey said. “The NRC has decided that the best way to shield itself from criticism around the decommissioning process is to take itself out of the process. In the latest version of the proposed decommissioning rule, the NRC would have no ability to approve, no ability to change, no ability to deny plants’ decommissioning proposals, known as post-shutdown decommissioning activities reports. Its only job would be to acknowledge receipt of the report. Our independent nuclear safety regulator would serve as a glorified filing cabinet. Ceding the job of regulator to the nuclear industry itself is not a win for safety, communities, or for the energy sector.”

Study: New U.K. nuclear likely to be lower carbon source than solar or wind

November 30, 2021, 9:30AMANS Nuclear Cafe

A recent study of life cycle carbon emissions at the United Kingdom’s Hinkley Point C nuclear plant finds that the facility, now under construction in Somerset, England, is likely to produce less CO2 over its lifetime than either solar or wind power.

According to the 70-page analysis—prepared by environmental consultancy Ricardo Energy & Environment for NNB Generation Company HPC Limited, the holding company for the Hinkley Point project—lifetime emissions from Hinkley Point C are likely to be about 5.5g CO2e per kWh. That amount also holds for the proposed Sizewell C plant, the study concludes. (The two 1,630-MWe EPRs at Hinkley Point C are currently scheduled to begin commercial operation in 2026 and 2027.)

Environmental group reports rise in support for nuclear

November 22, 2021, 9:19AMANS Nuclear Cafe

A new survey of Americans’ attitudes about energy by ecoAmerica, a Washington, D.C.–based environmental nonprofit, finds notable shifts in views on several energy sources, including nuclear energy, from 2018 to 2021.

The American Climate Perspectives Survey shows that national support for nuclear increased by 10 percentage points, from 49 percent to 59 percent. (The numbers reflect both strong and tepid backing.) Broken down by party affiliation, the survey shows Republican support holding steady at 64 percent, Independent support moving from 50 percent to 61 percent, and Democratic support rising, rather dramatically, from 37 percent to 60 percent.

Former NRC chairman Allison Macfarlane—nuclear agnostic or opponent?

Macfarlane

As noted by Newswire yesterday, former Nuclear Regulatory Commission chairman Allison Macfarlane describes herself as “agnostic” on the subject of nuclear energy. In the view of some, however, there is a more accurate way to describe Macfarlane’s nuclear stance.

In a November 15 blog post, Breakthrough Institute cofounder Ted Nordhaus suggests that Macfarlane can be considered a face of the modern antinuclear movement, the typical representative of which, he says, is not “a hippie with a No Nukes sign,” but rather “a highly credentialed progressive policy wonk, a lawyer, or academic, or journalist, who often claims not to be opposed to nuclear energy at all.”
