Small modular reactor developers Holtec International and GE Hitachi Nuclear Energy (GEH) are both looking to the United Kingdom as a prime location for deployment of their units—the SMR-160 and BWRX-300, respectively.
On December 19, Holtec Britain announced that it is poised to enter the United Kingdom’s generic design assessment (GDA) process for the SMR-160 early in 2023, enabling the start of construction of the first U.K. unit as soon as 2028. (The GDA, developed by the Office for Nuclear Regulation and the Environment Agency, gauges the safety, security, and environmental protection aspects of a nuclear plant design. Successfully completing the assessment culminates in a design acceptance confirmation from ONR and a statement of design acceptability from the Environment Agency.)

In the 1960s, nuclear energy established itself as a mainstay of the electrical grid for its ability to produce carbon-free, safe, and reliable power. Indeed, nuclear energy currently provides about 50 percent of carbon-free electricity in the United States, but a major challenge is its cost.

Holtec International is apparently not ready to give up on the Palisades nuclear power plant just yet. Despite having been denied federal funds last month for a possible reopening of the Covert, Mich., facility, the company this week announced its intention to reapply.

Since the inception of commercial nuclear power in the United States, every control room in every nuclear plant has looked essentially the same. You will see fixed alarm tiles, red and green lights, rows of switches, and analog meters. Until about a decade ago, you would even have seen paper charts (now replaced by digital versions of those same charts). Licensed operators have shown through a proven operating history that this control room design is safe and effective. Genius definitely went into the complexity of circuits and placement of switches and indications in the design, but things have come a long way over the years, and new technology, updated plant designs, and the need to improve efficiency and maintain reliability have impacted staffing and the role of operators. A control room update is long overdue. So, what lies ahead for the future of nuclear control room design? What possibilities exist for the next generation of plants?

While it currently has the lowest installed nuclear capacity of any nuclear-powered nation in Europe with one 482-MWe pressurized water reactor at Borssele, the Netherlands has in recent years been looking to move up in the rankings.

Unit 1 at South Korea’s Shin-Hanul nuclear power plant entered commercial operation last week, Korea Hydro & Nuclear Power has announced. The 1,340-MWe APR-1400—designed by KHNP and parent firm Korea Electric Power Company—achieved initial criticality on May 22 of this year and was connected to the grid on June 9.

The Nuclear Regulatory Commission has docketed Vistra Corporation’s license renewal application for the Comanche Peak reactors.
Operated by Vistra subsidiary Luminant and located in Glen Rose, Texas, the Comanche Peak plant is home to two pressurized water reactors. The original 40-year licenses for Units 1 and 2 expire in February 2030 and February 2033, respectively.

The British government has announced an investment of £679 million (about $828 million) in the proposed Sizewell C nuclear plant in Suffolk, England, confirming chancellor of the exchequer Jeremy Hunt’s remarks on the project in his November 17 Autumn Statement.
