Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

A sub-channels-inserted porous evaporator is proposed as a heat removal device of the divertor with a heat load exceeding 10 MW/m2. The porous medium is made by sintering copper particles of micro size in diameter and has several sub-channels to enhance discharge of generated vapor outside the porous medium. This porous cooling devise is attached onto the backside of the divertor and remove the heat by evaporating water passing through the porous medium against the heat flow. In order to prove the effect of the sub-channels, the heat transfer characteristics of this porous device are evaluated experimentally using a plasma arcjet as a high heat flux source. The result shows that the heat transfer performance of copper-particles-sintered porous medium with the sub-channels enables to remove much higher heat flux under lower flow rate and lower wall superheat conditions, compared with the normal porous media. The removal heat flux, 8.1 MW/m2, is 1.8 times as higher than that of the normal porous medium at a wall superheat of 50 degrees (the heat transfer coefficient, 1.6 × 105 W/m2/K, is 2.4 times as higher). The removal heat flux reaches almost 10 MW/m2 although the wall superheat exceeds 100 degrees (The wall temperature is approximately 220 degrees C. still in a fully developed boiling regime). In addition, the removal heat flux exceeds 20 MW/m2 by increasing the number of the sub-channels under lower wall superheat conditions, which proves high potential of the sub-channels-inserted porous evaporator.
