The Nuclear Regulatory Commission has issued a final safety evaluation report for the first of several licensing topical reports (LTR) submitted by GE Hitachi Nuclear Energy (GEH) for the BWRX-300 small modular reactor, the company announced on December 1.

The initial LTR, titled “BWRX-300 Reactor Pressure Vessel Isolation and Overpressure Protection,” was submitted to the NRC in December 2019, officially beginning the U.S. licensing process. This LTR forms the basis for the “dramatic simplification” of the BWRX-300, according to GEH.

In its announcement, GEH noted that two additional LTRs were submitted in early 2020 and that it anticipates reviews of those reports to be completed in the coming months. A fourth LTR was submitted in September 2020, the company added.

Unit 5 at China National Nuclear Corporation’s (CNNC) Fuqing nuclear plant in southeastern China’s Fujian Province has become the world’s first Hualong One reactor to be connected to the power grid, the company announced on November 27. “It was confirmed on-site that all technical indicators of the unit met the design requirements and that the unit was in good condition,” CNNC said.

Fuel loading at Fuqing-5 began on September 4, following the issuance of the reactor’s operating license by China’s Ministry of Ecology and Environment. The loading of 177 sets of fuel assemblies was completed on September 10, and initial criticality was achieved on October 21. The unit is scheduled to enter commercial operation before the end of the year.

Also known as the HPR1000, the Hualong One is a Chinese-designed and -developed 1,000-MWe Generation III pressurized water reactor, incorporating design elements of CNNC’s ACP1000 and China General Nuclear’s ACPR1000+ reactors. Fuqing-5’s twin HPR1000, Fuqing-6, is scheduled to start contributing power to the grid next year.

The inaugural World Nuclear Energy Day, on December 2, will be a celebration of nuclear energy and the people who make it happen. As nuclear power is a leading source of clean energy across the globe, the day aims to remind us that clean energy enables healthy lives.

Small modular reactor developer NuScale Power has announced the opening of the NuScale Energy Exploration (E2) Center at Oregon State University (OSU).

The E2 Center is designed to offer users a hands-on learning opportunity to apply nuclear science and engineering principles through simulated, real-world nuclear power plant operation scenarios, according to NuScale on November 17. The center employs state-of-the-art computer modeling within a simulator of the NuScale SMR power plant control room, allowing users to take on the role of control room operator at a 12-unit NuScale SMR plant to learn about the features and functionality unique to the company’s SMR technology.

More to come: The E2 Center at OSU is the first of three planned installations of a NuScale power plant control room simulator at U.S. universities. Support for the centers was provided by a grant in 2019 from the Department of Energy. Additional information on the E2 Center is available here.

The November issue of Nuclear News is focused on the individuals who make up our nuclear community.

We invited a small group of those individuals to tell us about their day-to-day work in some of the many occupations and applications of nuclear science and technology, and they responded generously. They were ready to tell us about the part they play, together with colleagues and team members, in supplying clean energy, advancing technology, protecting safety and health, and exploring fundamental science.

In these pages, we see a community that can celebrate both those workdays that record progress moving at a steady pace and the exceptional days when a goal is reached, a briefing is delivered, a contract goes through, a discovery is made, or an unforeseen challenge is overcome.

The Nuclear News staff hopes that you enjoy meeting these members of our community—or maybe get reacquainted with friends—through their words and photos.

With input from the American Nuclear Society and other organizations, the International Irradiation Association has published a white paper summarizing all of the significant uses of radiation processing and the global economic, social, and environmental benefits that arise from the technologies. The nontechnical document, Uses and Applications of Radiation Processing, is aimed at people and organizations that are not familiar with radiation processing, highlighting how irradiation is routinely used in an array of diverse and beneficial applications.

“Though largely unknown by the public, radiation processing, or ‘irradiation,’ touches everyone’s life,” states the paper, which was released on November 24.

The 11-page white paper goes on to summarize the applications of radiation processing, including medical sterilization, food irradiation, wastewater treatment, and other uses. An overview of the different technologies used to irradiate materials, including gamma, electron beam, and X-ray sources, is also provided.

A final report on the dry storage and transportation of high-burnup spent nuclear fuel (NUREG-2224) has been issued by the Nuclear Regulatory Commission. NUREG-2224 provides a technical basis in support of the NRC’s guidance on adequate fuel conditions as it pertains to hydride reorientation in the cladding of high-burnup spent fuel (over 45 gigawatt-day per metric ton uranium).

NUREG-2224, “Dry Storage and Transportation of High Burnup Spent Nuclear Fuel,” was made publicly available on November 23 on the NRC’s ADAMS website with Accession No. ML20191A321.

Ontario Power Generation (OPG) recently announced the resumption of planning activities for future nuclear power generation at its Darlington site, with a goal of hosting a grid-size small modular reactor as soon as 2028. Originally, plans for the Darlington new nuclear project were focused on the construction of traditional large reactors.

Located in Clarington, Ontario, Darlington is the only site in Canada currently licensed for new nuclear. OPG was granted a license from the Canadian Nuclear Safety Commission (CNSC) in 2012 to allow site preparation activities for the project. The company has applied to renew the license, which is set to expire in August 2022. The CNSC will hold a public hearing on June 9–10, 2021, to consider the license renewal.

Early last month, OPG announced that it was working with three grid-scale SMR technology developers—GE Hitachi, Terrestrial Energy, and X-energy—to advance engineering and design work, with the goal of identifying options for future deployment.

The Department of Energy plans to provide $100 million over the next four years for new research in high-energy physics. The research is expected to focus on topics such as the Higgs boson, neutrinos, dark matter, and dark energy in an effort to advance understanding of the universe at the most fundamental level. The Office of High Energy Physics (HEP) within the DOE’s Office of Science is sponsoring the research funding opportunity.

The DOE’s funding opportunity announcement, “FY 2021 Research Opportunities in High Energy Physics,” can be found on the HEP funding opportunities page.

High-energy physics serves as a cornerstone of America’s science efforts, the DOE said on November 17, adding that it plays a major role in nurturing top scientific talent and building and sustaining the nation’s scientific workforce. Applications will be open to universities, industry, and nonprofit institutions, with awards selected by competitive peer review and contingent on congressional appropriations.

The third part of the“Advanced Nuclear Reactors and Power Systems” sessions during the 2020 ANS Virtual Winter Meeting featured an examination of the status of various advanced reactors. The sessions were sponsored by the Operations and Power Division and chaired by Piyush Sabharwall of Idaho National Laboratory.

Here is an article on the first "Advanced Nuclear Reactors and Power Systems” session.

Presentation topics in the third and final session included using Modelica for system-level modeling and simulation of advanced reactors; the testing of fast-spectrum reactors’ gears and bearings in liquid sodium; and the creation of a simple core analysis tool called the Thermal hydrAulic COre Calculations using the single heAted channel meThod (TACOCAT) code.

Robotics and remote systems have been used for supporting nuclear facilities since the dawn of the atomic age. Early commercial nuclear plants implemented varying levels of automation and remote operation, such as maintenance activities performed on the reactor pressure vessel and steam generators. Over the past several decades, there has been a steady progression toward incorporating more advanced remote operations into nuclear plants to improve their efficiency and safety. One of the primary forces driving the adoption of robotic tooling in U.S. nuclear power plants is money.

The economic model for the U.S. operating fleet has changed considerably over the past 10 to 12 years. Regulations in the nuclear industry have rarely decreased and, more often than not, have increased. This has led to nuclear plants in certain energy markets being hindered financially and thus needing to find ways to optimize their operations to do more with the resources they have. At the same time, the reliability and flexibility of robotics and automated systems have been increasing while their costs have been decreasing, making robotic systems much safer and more available to use. This has helped drive utilities to explore new ways of using robotics to overcome the obstacles they are facing. One of the obstacles that power plants have been tackling has been shortening the duration of their refueling outages to decrease their costs and increase their revenue.

“Advanced Nuclear Reactors and Power Systems-I” on November 18 during the 2020 ANS Virtual Winter Meeting was the first of a three-session set examining the status of various advanced reactors. The sessions were sponsored by the Operations and Power Division and chaired by Piyush Sabharwall of Idaho National Laboratory.

Presentation topics in the first session included the core design and helium Brayton cycle design of the Holos-Quad microreactor, a microreactor design for a truck charging station, and a levelized cost of electricity (LCOE) estimation on HALEU (high-assay low-enriched uranium) fuels for small modular reactors.

Here are some highlights:

ANS President Mary Lou Dunzik-Gougar took to the video screen on November 18 during the 2020 ANS Virtual Winter Meeting for the President’s Special Session on radiation risk, echoing a comment by Exelon Nuclear’s Bryan Hanson, the Winter Meeting’s general cochair, who earlier in the week characterized radiation as one of the most misunderstood aspects of nuclear.

“I think that’s very true,” Dunzik-Gougar said. “So much misconception and misunderstanding. I have always had a passion for communicating about such things as radiation, helping people understand the nature of radiation and the relative risks of nuclear, but mostly about its benefits. But I think we in the industry can better prepare ourselves with knowledge about radiation and its impacts and also educate ourselves on how to talk about the risks of radiation with people not in our own echo chambers to help change the perception among a broader scope of people.”

The panel of experts assembled to help impart some of that knowledge to session attendees included Amir A. Bahadori, assistant professor at Kansas State University; Donald A. Cool, a technical executive at the Electric Power Research Institute and a former senior executive at the Nuclear Regulatory Commission; Paul Locke, associate professor at the Johns Hopkins Bloomberg School of Public Health; and Shaheen Dewji, assistant professor at Texas A&M University.

The Department of Energy won’t publish its draft environmental impact statement (EIS) for the Versatile Test Reactor (VTR) until mid-December. In a November 19 announcement on Twitter, however, the DOE’s Office of Nuclear Energy said that the yet-to-be-released EIS lists Idaho National Laboratory as the preferred alternative to site the VTR.

The DOE plans to submit the draft EIS for public comments early next month. The DOE won’t make a final decision on the design, technology selection, and location for the VTR until the completion of the EIS and record of decision in late 2021.

The session titled “Energy Storage Integration with Nuclear Power Plants,” held on November 17 during the 2020 ANS Virtual Winter Meeting, was sponsored by the Operations and Power Division and chaired by Piyush Sabharwall, of Idaho National Laboratory.
