President Joe Biden has signed the ‘‘Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy Act of 2024,” or ADVANCE Act. This legislation speeds up the permitting process and creates new incentives for the buildout of nuclear reactors. An article examining this significant legislative action was recently published in Power Engineering. According to the article, this act will […]
Preferred Engineering’s Best Practices for Jet Pump Plugs
The jet pump plug is an essential tool used in the maintenance of Boiling Water Reactors (BWRs) in nuclear power plants. The jet pump system involves driving water through a nozzle to create a high-velocity jet, which in turn induces a lower pressure that draws additional water along with it, effectively mixing and circulating the water. Jet pump […]
