Ontario Power Generation’s (OPG) massive project to refurbish all of its Darlington nuclear power plant reactors has reached its first major milestone with the successful completion of Unit 2’s refurbishment and reconnection to Ontario’s electricity grid, the utility stated in a June 4 media release.

The Darlington plant, located in Clarington, Ontario, Canada, houses four 878-MWe PHWR CANDU reactors, all of which entered commercial operation in the early 1990s. The 10-year refurbishment project, which also was 10 years in the planning, began in earnest in October 2016, when Unit 2 was taken off line (NN, Dec. 2016, pg. 45).

The European Commission released a plan for rejuvenating Europe’s pandemic-damaged economy, including a green energy program that calls for “rolling out renewable energy projects, especially wind [and] solar, and kick-starting a clean hydrogen economy.” No mention was made of nuclear energy, however, an omission for which the commission was taken to task that same day by Foratom, the Brussels-based trade association for the European nuclear energy industry.

Workers at the Hinkley Point C nuclear construction project in the United Kingdom have completed the 49,000-ton base for the station’s second reactor, Unit C2, hitting a target date set more than four years ago, according to EDF Energy.

Gender Champions in Nuclear Policy (GCNP), launched in November 2018, has released a report on the progress made during its inaugural year toward its goal of achieving gender equity in the nuclear policy field. According to a May 28 announcement, the group has had “mostly positive results.”

Électricité de France subsidiary EDF Energy has submitted an application to the United Kingdom government’s Planning Inspectorate for a development consent order (DCO) to build a new power station, Sizewell C, at the Sizewell nuclear site in Suffolk. The agency received the application on May 27, after it had been deferred for two months because of the COVID-19 pandemic.

Robert J. Feitel was sworn in on May 28 by Nuclear Regulatory Commission Chairman Kristine Svinicki as the agency’s new inspector general. Feitel replaces Hubert T. Bell, who retired in 2019.

The Akademik Lomonosov, the world’s only floating nuclear power plant, has been fully commissioned, reports Rosatom, Russia’s state atomic energy corporation.

In the early years of the Nuclear News capacity factors survey, any factor over 70 was deemed excellent; any factor under 50 was considered poor. By that standard, all but two operating U.S. power reactors chalked up excellent performance during 2017–2019. A record 809.4 TWh of electricity was generated in the United States from nuclear energy in 2019, according to the U.S. Energy Information Administration (EIA), besting the record of 807.1 TWh set in 2018.

Nuclear News staff developed the capacity factors survey in the early 1980s as a way to identify the most productive reactors in an expanding fleet. Fleet improvement was the industry’s self-identified goal, but no one could anticipate the startlingly rapid pace of improvement, spurred by the Institute of Nuclear Power Operations (INPO), which boosted fleetwide performance to highs that continue today.

The Nuclear Regulatory Commission recently issued its Enforcement Program Annual Report for calendar year 2019, showing that 57 escalated enforcement actions were taken against NRC licensees last year. These actions included notices of violation (NOV ) of Severity Level III or higher, NOVs associated with findings of low-to-moderate, substantial, or high safety significance (color coded as white, yellow, or red findings, respectively), civil penalties, and orders, including confirmatory orders.

The Nuclear Regulatory Commission on May 18 sent a letter to Vice President Mike Pence in response to a coalition of critics who had written to the vice president in April, taking issue with the agency’s COVID-19–related actions.

The Blue Ridge Environmental Defense League (BREDL), a North Carolina–based antinuclear organization, is claiming that Vogtle-3—one of two 1,100-MWe AP1000 pressurized water reactors currently under construction at the Vogtle nuclear plant near Waynesboro, Ga.—is sinking.

The Nuclear Regulatory Commission is taking comments on its “Proposed Rule for Emergency Preparedness for Small Modular Reactors and Other New Technologies,” published in the Federal Register on May 12. The proposed rule and associated draft regulatory guide apply to non–light-water reactors and certain nonpower facilities.

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.
