Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

FIA publishes “snapshot in time” fusion industry report
Following new federal funding and programs announced in June to support a “bold decadal vision” for fusion energy in the United States, and the enactment of the Fusion Energy Act in July, fusion energy trade group the Fusion Industry Association has released its latest annual survey of fusion companies: The Global Fusion Industry in 2024.
This fourth annual report includes responses from three companies that were not surveyed in 2023 as well as an additional $900 million of reported funding in the past year. That’s growth—but growth that falls short of the “bold” expectations set by the eye-popping $2.8 billion of funding reported by private companies in 2022, as media outlets—including Reuters, with the headline “Global Fusion Energy Investment Growth Falls for Second Year”—were quick to point out.

This study considers ways that the proposed Engineering Test Reactor (ETR), or the proposed International Tokamak Reactor (INTOR), can be used for magnet performance tests that would be useful for the design and operation of the Demonstration Tokamak Power Plant (DEMO). Such testing must not interfere with the main function of the ETR/INTOR as an integrated fusion reactor. A performance test plan for the ETR/INTOR magnets is proposed and appropriate tests on the magnets for each phase of the ETR/INTOR operation are described. The suggested tests would verify design requirements and monitor long-term changes due to radiation. This paper also summarizes the design and operational performance of existing superconducting magnets and identifies the known failures and their predominant causes. In addition, existing radiation dose-damage information and criteria that relate material property change with component failure are combined with predicted neutron and gamma dose rates at the ETR/INTOR magnet position to estimate the time to insulator and conductor failure in this reactor. Long-term operation of magnets in a pulsed plasma environment such as in the ETR/INTOR, however, may aggravate the effect of gamma and neutron radiation on the insulators. To provide more accurate time-to-failure information for magnet component material, accelerated irradiation of magnet material coupons in the ETR/INTOR and in other irradiation facilities is suggested.
