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.

TVA to file for Clinch River SMR construction permit by June
In a Q&A posted on TVA’s website last week about a “new nuclear heyday,” Bob Deacy shared his vision for the Clinch River nuclear site in Oak Ridge, Tenn.—and some news about next steps for the company’s small modular reactor plans.
The Tennessee Valley Authority’s senior vice president for the Clinch River project, Deacy described his vision for up to four SMRs built on plots smaller than a football field with state-of-the-art digital equipment and a newly trained workforce providing reliable 24/7 power to the grid.

A computer simulation model developed in the ANSYS Fluent 2022 version R2 package was used for the engineering analysis required to design a counterflow matrix heat exchanger (MHE) for cooling a hydrogen stream. The theoretical data obtained with the simulation model were compared with the experimental data collected during the experimental campaigns carried out in the Cryogenics Laboratory of ICSI Rm. Valcea.
The MHE was tested for three test regimes obtained by theoretical correlations applicable to the current configuration. The Nusselt number, friction factor, and performances theorized by different authors, such as Gnielinski, Miheev, and Mikulin et al. were evaluated. This paper presents comparisons between the results obtained with the simulation model, the experimental values, and the theoretical models from the literature, highlighting the possibility of developing a mathematical model that can be applied to the calculation and design of a MHE.
