Advanced reactors and small modular reactors with strikingly different coolants and sizes offer an array of different benefits, but when it comes to fuel cycle issues, including spent fuel and waste, they have a lot in common with conventional light water reactors. Two reports released within the last week—a National Academies of Sciences, Engineering, and Medicine (NASEM) consensus committee report two years in the making and a Department of Energy study released by Argonne National Laboratory—address the timely topic of advanced reactor fuel cycle issues. While the NASEM committee ventured to define research and infrastructure needs to support the entire nuclear power fuel cycle, inclusive of new technologies, for decades to come, the DOE report compares the front- and back-end fuel cycle metrics of three reactor designs (from NuScale Power, TerraPower, and X-energy) that have been selected for DOE cost-share–funded demonstrations within this decade. Together, these reports provide assurance that the fuel cycle needs of a fleet of new reactors can be met and point to near-term research and planning needs.

The Department of Energy is offering cost-shared funding that could lead to the demonstration of an “energy park” drawing 20–300 MW of thermal energy from a U.S. nuclear power plant under a funding opportunity amendment issued in August by the DOE’s Office of Nuclear Energy Light Water Reactor Sustainability (LWRS) program, in coordination with the DOE’s Office of Energy Efficiency and Renewable Energy Hydrogen and Fuel Cell Technologies Office.

Nuclear energy offers a pairing of high capacity factors and low carbon emissions unrivaled by other power sources, and advanced reactors and small modular reactors (SMRs) hold promise to deliver that power with even more efficiency and versatility. Researchers in the public and private sectors, backed by government funding through programs like the Department of Energy’s Advanced Reactor Demonstration Program and Advanced Research Projects Agency–Energy (ARPA-E), are bringing that promise closer to fulfillment by engineering solutions to open questions about advanced reactor materials and fuel cycles.

The American Nuclear Society has just published ANSI/ANS-55.1-2021, Solid Radioactive Waste Processing System for Light-Water-Cooled Reactor Plants. The standard was originally issued in 1979 with a revision in 1992 to provide design guidance for in-plant solid radwaste systems.

If you’re hearing for the first time that October 8 is Hydrogen Day, you might be wondering, “Why October 8?” and “What’s the connection to nuclear?”

ANS Nuclear Newswire has the answers.

Arizona Public Service is the latest nuclear utility with confirmed plans to install hydrogen production capacity, an investment decision that is based on analysis conducted under the Department of Energy’s H2@Scale program and backed by a $20 million DOE award.

The final text of the approximately 5,600-page Consolidated Appropriations Act 2021 was released on December 22. While the timing of final passage is still fluid, the Senate was expected to approve it and send it on to President Trump to sign into law, according to John Starkey, American Nuclear Society government relations director.

Below are some key funding highlights from the legislation pertaining to nuclear energy.

Working in INL’s Human Systems Simulation Laboratory, senior R&D scientist Ahmed Al Rashdan co-developed the Advanced Remote Monitoring project for the LWRS Program.

There are numerous similarities between auto racing pit crews and the people in the nuclear power industry who get us through outages: Pace. Efficiency. Diagnostics. Teamwork. Skill. And safety above all else.

To Paul Hunton, a research scientist at Idaho National Laboratory, the keys to successfully navigating a nuclear plant outage are planning and preparation. “When you go into an outage, you are ready,” Hunton said. “You need to manage outage time. You want to avoid adding delays to the scheduled outage work because if you do, it can add a couple million dollars to the cost.”

Hunton was the principal investigator for the September 2019 report Addressing Nuclear Instrumentation and Control (I&C) Modernization Through Application of Techniques Employed in Other Industries, produced for the U.S. Department of Energy’s Light Water Reactor Sustainability (LWRS) Program, led by INL. Hunton drew on his experience outside the nuclear industry, including a decade at Newport News Shipbuilding.

Producing hydrogen as well as electricity from the current fleet of nuclear reactors is garnering a lot of interest from stakeholders, according to representatives of four nuclear operating utilities that together operate about one-third of the U.S. nuclear fleet. That interest drew viewers to a Utility Roundtable on U.S. Leadership in Sustaining Clean, Competitive Power and Hydrogen during the June 8 opening plenary of the American Nuclear Society's 2020 Virtual Annual Meeting.
