Instructed by GSE TrueNorth. Part of the GSE Solutions group, that leverage decades of specialized expertise in thermal performance and engineering programs that refine and update systems, to optimize performance and safety.

“The instructor was well-versed in the Code and dealing with real-life situations associated with the Code and plant operation. His teaching was much more than academic. Classroom OE examples and hypothetical questions were good for learning and understanding.”
