Nuclear Plant Performance Program Combined (HXPUG, P2EP, SWAP) Users Group Meetings – January 2023

We will be exhibiting at this years Nuclear Plant Performance User Group in Atlanta GA on January 23-26 at the Grand Hyatt Atlanta in Buckhead hotel.

The Heat Exchanger Performance User Group (HXPUG) Meeting is for nuclear industry personnel involved with performance and maintenance of heat exchangers. The Plant Performance Enhancement (P2EP) Program is for thermal performance engineers to discuss research to improve the heat rate of nuclear power plants, thereby increasing unit average capacity and reducing plant operations and maintenance costs per kilowatt-hour.

Quick Cleaning Turnaround On Critical Boiler Unit At GA Paper Mill Using Our Proprietary Remote Equipment

October of 2022, Hennigan was awarded an outage contract from a major Paperboard manufacturer in Macon, GA. One of Hennigan’s projects within the outage was to clean the main Boiler unit. This boiler system is 30-ft wide x 60-ft long by 200-ft tall. Using Hennigan’s specialized equipment, the boiler cleaning was set-up, executed, torn down, inspected by facility engineers, and ready to go back on-line in a single 12-hour work shift. Hennigan’s use of proprietary remotely operated equipment and tooling, allowed us to accomplish this time sensitive work successfully. This level of performance is what our clients have come to expect, and we take pride in delivering!
