EIA: Nine of top 10 electricity generators in 2019 were nuclear plants

Graph: EIA

Of the 10 U.S. power plants that generated the most electricity in 2019, nine were nuclear plants, a recent report from the U.S. Energy Information Administration states.

These 10 facilities produced a combined 230 million megawatt hours of electricity last year, accounting for 5.6 percent of all electricity generation in the United States, according to the report. The report also notes a shift in the makeup of the top plants over the past 10 years, from a mix of nuclear and coal-fired generators in 2010 to nearly all nuclear in 2019.

Coal’s share of U.S. electricity generation dropped from 45 percent in 2010 to 23 percent in 2019, the reports says. Stricter air emission standards and decreased cost competitiveness relative to other generators are given as the key reasons for coal’s decade of decline.

NRC proposes six-figure fine to TVA; cites two former execs

In actions related to its rules involving employee protection, the Nuclear Regulatory Commission on August 24 issued a proposed civil penalty of $606,942 to the Tennessee Valley Authority, as well as an order prohibiting a senior TVA executive from NRC-licensed activities for five years and a violation notice to a second executive.

Following investigations completed in October 2019 and January 2020, the NRC concluded that two former TVA employees had been subjected to reprisals for raising concerns regarding a chilled work environment.

UT, TVA to evaluate SMR development at Clinch River

The University of Tennessee (UT) and the Tennessee Valley Authority (TVA) signed a memorandum of understanding on April 7 to evaluate the development of a new generation of cost-effective advanced nuclear reactors, such as small modular reactors (SMR), at TVA’s 935-acre Clinch River Nuclear Site in Roane County, Tenn.

Nuclear Matinee: Prep work at Sequoyah Unit 2

Today's ANS Nuclear Matinee shows viewers a time-lapse film of a steel superstructure being built on top of the dome of Sequoyah-2's reactor containment building. The work is being done to ready the site for a large maintenance project scheduled at the plant. When complete, the superstructure will support the removal of parts of the dome along with the reactor containment vessel and steam generator enclosures.

The future of nuclear at #MOXChat

On September 11, the National Nuclear Security Administration (U.S. Department of Energy) hosted a public meeting in Chattanooga, Tenn., concerning its Supplemental Environmental Impact Statement on the disposition of surplus weapons-grade plutonium as mixed-oxide (MOX) fuel for use in power reactors. You may have seen the ANS Call to Action for the hearing and perhaps read the ANS position statement or background information.

Dr. G. Ivan Maldonado presents ANS comments at TVA Board hearing

On August 16, G. Ivan Maldonado, PhD, Associate Professor of Nuclear Engineering with the University of Tennessee-Knoxville, attended a Tennessee Valley Authority (TVA) Board Meeting on behalf of the American Nuclear Society to present comments on the use the of mixed uranium-plutonium oxide (MOX) fuel technology to accomplish the timely disposition of surplus weapons-grade plutonium.
