Digital twins and nuclear plants

October 6, 2023, 3:01PMNuclear NewsJeff Lane, Tannis Liviniuk, Bristol Hartlage, and Jim Harrell

A digital twin is a virtual replica of a real system or physical asset. It is a trusted data source containing vital information about an asset, which could include dimensions, relevant manufacturer information, operations history, and maintenance records. To realize the maximal benefit from a digital twin at a nuclear power plant, for example, it must evolve as the facility is designed, constructed, and operated. Some general attributes and the resulting benefits of a digital twin follow:

It integrates information to a single location

Ease of access

It connects to the physical asset

Continuous monitoring

It dynamically learns and updates

Evolves with the asset

NRC to discuss proposed fusion regulations

October 6, 2023, 9:30AMNuclear News

The Nuclear Regulatory Commission on October 4 made available preliminary proposed rule language for the licensing and regulation fusion energy systems. The proposed rulemaking, which would amend parts 20, 30, and 51 of Title 10 of the Code of Federal Regulations, would provide a limited-scope, technology-inclusive regulatory framework for a broad array of fusion systems currently under development.

2023 ANS Winter Conference and Expo coming to Washington, D.C.

October 6, 2023, 7:00AMANS News

The American Nuclear Society’s largest and most anticipated annual event, the Winter Conference and Expo, will take place November 12–15 at the Washington Hilton in Washington, D.C.

This year’s theme is “Maintaining the Momentum,” which suits nuclear energy’s current moment in the spotlight. In the last few years, public investment in both new and existing nuclear technology has expanded alongside a rise in public support and acceptance. Now is the perfect time for the nuclear industry to seize this momentum by coming together to maintain current nuclear plants, expand the nuclear workforce, strengthen supply chains and infrastructure, increase public and private sector investments, and continue to advocate for the benefits of nuclear power.

When Norway’s Halden research reactor shut down in 2018, nuclear researchers around the world were forced to scramble. For 60 years, the Halden Reactor Project offered a 25-MWt boiling water reactor for research where scientists could expand their understanding of nuclear fuel reliability, reactor internals, plant procedures and monitoring, and human factors.

ANS congratulates Mehdi Sarram on 60 years of membership

October 4, 2023, 3:14PMANS News
ANS Executive Director/CEO Craig Piercy presented a certificate commemorating Sarram’s 60 years as an ANS member.

The American Nuclear Society is pleased to celebrate Mehdi Sarram on the 60th anniversary of his membership. He joined the Society in 1963 when he was an undergraduate in nuclear engineering at the University of Michigan and has since served the nuclear energy industry as a nuclear engineer, reactor operator, professor, and mentor. Over the years, Sarram has been active in several local ANS sections and has made remarkable contributions to the peaceful uses of nuclear energy, including bringing Iran’s first nuclear reactor to full power.
