Lawmakers press DFC to invest in nuclear

December 19, 2022, 9:30AMNuclear News

A bipartisan group of senators sent a letter last week to Scott Nathan, chief executive officer of the U.S. International Development Finance Corporation (DFC), urging the agency to begin financing nuclear energy projects and support the continued development and deployment of advanced nuclear technology.

Signing the December 8 letter were Sens. John Barrasso (R., Wyo.), Cory Booker (D., N.J.), Shelley Moore Capito (R., W.Va.), Ben Cardin (D., Md.), Chris Coons (D., Del.), Kevin Cramer (R., N.D.), Joe Manchin (D., W.Va.), Lisa Murkowski (R., Alaska), and Jim Risch (R., Idaho).

Rethinking operations through digital control room design

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.

Germany’s winter to wonder “What if . . . ?”

December 13, 2022, 12:00PMNuclear News

Meteorological winter is here, and a chill is gripping northern Europe. Predictably, renewable generation has entered a seasonal lull and heating demand is up, despite a push to conserve natural gas, which means electricity and gas bills are up too. With a grudging nod to reality, German chancellor Olaf Scholz ensured in October that Germany’s three remaining nuclear power reactors will provide a few more months of clean, reliable power. Their premature closure, once scheduled for December 31, is now expected by April 15, 2023.

Mothers (for Nuclear) know best

In late 2015, we heard rumors that Diablo Canyon was under threat of premature closure. As details emerged, we realized the situation was dire—similar stories were emerging around the country and the world. Nuclear plants were shutting down early for reasons that had nothing to do with plant conditions or operations, but because of politics and poor public perception.

We started brainstorming possible ways we could help, then realized our efforts had to be about more than just one plant. We knew we were in a bit of a unique position. There aren’t a whole lot of women in our industry—­especially not hippie environmentalist moms. Our story is interesting in that we were initially skeptical about nuclear power, asked questions over many years, and eventually changed our minds to support it.

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.

How excellence in plant operations will lead to a brighter nuclear future

For years the U.S. nuclear industry has done an outstanding job keeping plant availability high while simultaneously continuing to improve safety and economics. With capacity factors averaging more than 90 percent, you would think that no one would shut down an operational nuclear power plant. But that is what we have seen in a number of cases. Fortunately, this now seems to be changing. As I write this column, Diablo Canyon’s new life extension application has just been submitted to the Nuclear Regulatory Commission for review, and the Department of Energy’s program to support continued operation of nuclear power plants is providing hope that current plants will continue to have the opportunity to demonstrate their operational excellence.

How did we get here? When I ask this question—both of myself and the industry as a whole—I envision this as two sides of the same coin. Through the efforts of many we have improved our financial and economic viability, but challenges remain because the full value proposition of nuclear energy has not been realized.

Mobile unmanned systems, also known as MUS, encompass a range of robotic devices, including drones, ground vehicles, crawlers, and submersibles. They are used for a wide range of industrial and defense applications to automate operations and assist humans or completely remove human workers from hazardous conditions. Robotics are ubiquitous in industrial manufacturing. Military robots are routinely employed in combat support applications, such as reconnaissance, inspection, explosive ordnance disposal, and transportation. Drones are used in many industries for security and monitoring, to conduct aerial inspections or surveys, and to capture digital twins. Wind and solar farms use MUS technologies for day-to-day operations and maintenance.

Hunt

U.K. chancellor of the exchequer Jeremy Hunt last week assuaged any concerns that Britain’s nuclear energy advocates might have been harboring regarding the new government’s support for the proposed Sizewell C plant. (The United Kingdom is on its third prime minister since July, when Boris Johnson’s government granted EDF Energy its long-awaited development consent order for the new nuclear build project.)

What he said: In his November 17 Autumn Statement, while noting the United Kingdom’s status as “a global leader in renewable energy,” Hunt added, “We need to go further, with a major acceleration of home-grown technologies like offshore wind, carbon capture, and storage, and, above all, nuclear. This will deliver new jobs, industries, and export opportunities and secure the clean, affordable energy we need to power our future economy and reach net zero."
