A massive water tank has been placed atop the containment vessel and shield building roof at Vogtle-3, one of two AP1000 reactors currently under construction at Southern Company’s nuclear expansion project near Waynesboro, Ga. The installation represents the final module placement for the unit and marks the latest significant milestone to be reached at the Vogtle site.

The Nuclear Alternative Project (NAP), a nonprofit group supporting the use of advanced reactors in Puerto Rico, has released the findings of a preliminary feasibility study undertaken to explore in detail the potential for these devices on the Caribbean island. The 288-page study, Preliminary Feasibility Study for Small Modular Reactors and Microreactors for Puerto Rico, was sponsored by the Department of Energy. The study concludes that small modular reactors and microreactors could be part of Puerto Rico’s energy portfolio and potentially supply a substantial part of a strong and diverse zero-emission energy mix.

Emirates Nuclear Energy Corporation (ENEC) has completed cold hydrostatic testing at Unit 4 of the Barakah nuclear power plant, the Arab world’s first such facility, located in Abu Dhabi. According to a May 19 ENEC press release, the testing incorporated lessons learned from the plant’s three other units and is a crucial step toward Unit 4’s completion. All four units are 1,345-MWe APR1400 pressurized water reactors. Abu Dhabi is the capital city of the United Arab Emirates.

A bipartisan group of senators is calling on the Nuclear Regulatory Commission to accelerate the completion of a rulemaking that would establish a technology-inclusive regulatory framework for advanced nuclear reactor technologies.

In a May 15 letter to NRC Chairman Kristine Svinicki, Sens. John Barrasso (R., Wyo.), chairman of the Senate Committee on Environment and Public Works, Sheldon Whitehouse (D., R.I.), Mike Crapo (R., Idaho), and Cory Booker (D., N.J.) note that the Nuclear Energy Innovation and Modernization Act (NEIMA)—signed into law by President Trump in January 2019—requires the NRC to, among other things, complete a rulemaking to license and regulate these technologies no later than December 31, 2027.

Southern Company subsidiary Georgia Power has placed the integrated head package (IHP) atop the Unit 3 reactor vessel at the Vogtle nuclear expansion project near Waynesboro, Ga., marking the latest major milestone in the construction of the first new U.S. nuclear reactors in more than 30 years.

Reactor designers and others ready to invest in advanced nuclear technology now have a defined route to apply for cost-share funding, including $160 million in initial funding to build two reactors within the next five to seven years. On May 14, the U.S. Department of Energy issued a funding opportunity announcement (FOA) for the new Advanced Reactor Demonstration Program (ARDP).

Several companies involved in the front end of the nuclear fuel cycle have recently resumed production after announcing temporary shutdowns or staffing reductions during the initial response to the COVID-19 pandemic.

Sens. Lisa Murkowski (R., Alaska) and James Risch (R., Idaho) have introduced legislation to bolster safeguards for U.S. critical electric infrastructure. Dubbed the Energy Infrastructure Protection Act, the bill updates provisions in the Federal Power Act and restricts federal disclosures of certain sensitive energy information.

Nuclear power plant performance includes both operational and safety aspects and is an outcome of numerous elements, such as the reliability of equipment, reduction in challenges to plant operations, protection of workers, and proficiency of operations. These elements are inextricably linked to each other and to the safety of each facility. In short, a well-run plant is a safe plant for the workers and the public, and a well-run plant is an efficient plant. By-products of high performance include improved regulatory performance, worker safety, plant reliability, and, most important, public health and safety.

Virginia-based Dominion Energy has agreed to pay $25 million to settle a Securities and Exchange Commission (SEC) case regarding the Summer nuclear expansion project, abandoned by owners SCANA and Santee Cooper in 2017, prior to the Dominion/SCANA merger.

“Our ability to produce domestic nuclear fuel is on the verge of a collapse,” Department of Energy Assistant Secretary for Nuclear Energy Rita Baranwal said in an article posted on the DOE’s website on May 11. “This is not an easy problem to fix, but the United States has a plan.”

Southern Nuclear has accepted a “white” finding (one of low to moderate safety significance) and an associated violation notice from the Nuclear Regulatory Commission for a problem at the company’s Vogtle nuclear plant, near Waynesboro, Ga. Earlier this year, Southern had contested the severity of the finding, arguing to no avail that the finding be more appropriately characterized as “green” (very low safety significance).

According to the federal government, certain critical infrastructure industries have a special responsibility during the coronavirus pandemic to continue operations, including the nuclear power industry.

Four of six Illinois nuclear power plants—Braidwood, Byron, LaSalle, and Quad Cities—set operational records while conducting spring refueling outages amid the COVID-19 pandemic.

Performance records include the shortest refueling outage (18 days) at LaSalle; the shortest refueling outage at Quad Cities (16 days), as well as the completion of the site’s longest continuous run (722 days); and the completion at both Braidwood and Byron of their sixth consecutive continuous cycle of operations, also known as a “breaker-to-breaker” run, according to a May 7 press release from Exelon Generation. Exelon’s average outage duration in Illinois this spring was 17 days, a full two weeks shorter than the national average, the release stated.

The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) has issued a report recommending approval of Dominion Energy’s 20-year subsequent license renewal (SLR) application for Surry-1 and -2. The board reached its conclusion during its April meeting, after reviewing both the SLR application and the associated final safety evaluation report. Dominion submitted the application in October 2018.

A request to the Nuclear Regulatory Commission that it suspend all rulemakings and other activities involving public comment or participation has failed to receive the petitioners’ desired response from the agency.

In a letter dated April 8, representatives of 82 largely antinuclear organizations—including Beyond Nuclear, the Natural Resources Defense Council, the Nuclear Information and Resource Service, Public Citizen, and the Sierra Club—argue that the public’s role in NRC rulemaking and licensing decisions is not being properly protected during the coronavirus pandemic.

Nuclear energy demand and output could be reduced by 2.5 percent this year compared with 2019, according to the report Global Energy Review 2020 from the International Energy Agency (IEA). The report states that global nuclear power generation fell by about 3 percent in the first quarter of 2020 compared with the same period in 2019, adding that the decline was due to lower electricity demand as well as delays for planned maintenance and construction of several projects.

The Nuclear Regulatory Commission is developing a generic environmental impact statement (GEIS) for small-scale advanced reactor designs. Just how small a reactor must be to fit the parameters of the GEIS is one topic open for public comment, but the NRC staff anticipates including reactors generating up to 30 MWt. The public comment period is open until June 30

Robert Feitel, speaking at his December 3, 2019, nomination hearing before the Senate Environment and Public Works Committee’s Subcommittee on Clean Air and Nuclear Safety.

The Senate voted unanimously 87–0 on May 4 to confirm Robert Feitel as the inspector general of the Nuclear Regulatory Commission. The position had been vacant since the end of 2018, when the NRC’s longtime IG Hubert T. Bell retired.

A Department of Justice attorney, Feitel was nominated for the job by President Trump in October last year, and in December he was approved by the Senate’s Environment and Public Works Committee, also by unanimous vote.

Despite its recent decision to trim the workforce at the Vogtle reactor construction project by about 20 percent to better address the COVID-19 pandemic, Southern Company is confident that Units 3 and 4—twin AP 1000 pressurized water reactors—will be up and running according to schedule.
