“The course was presented with many great points for a wide range of fields. It was Excellent. George kept the subject lively given when the sections were not as exciting.”
— Pressure Systems Designer, Sierra Lobo Inc / NASA Goddard, United States

“Excellent training course; please continue with the online training offerings as it allows an international audience to gain easier access to the knowledge of experts like George Antaki. Excellent, knowledgeable presenter able to provide background information on API 579 code content.”
— Integrity Engineer, SASOL, South Africa

“The training was superb, the instructor really strong in his subject, the experience sharing together with in depth theoretical knowledge really help us to understand this difficult code. The instructor and other invited guess speaker are really strong at their field. All questions are answered in a passionate manner. Keep up the good momentum.”
— Materials and Corrosion Engineer, Shell, Malaysia

“Many real life examples and history. The background and derivations of equations and practices was very useful. George’s delivery and expertise is vast and far reaching. Many years of experience distilled in an aasy to digest format.”
–Pressure Systems Engineer, Sierra Lobo, United States

“Excellent course and also great instructor.”
— Inspection Engineer, ANCAP, Uruguay

The first part of this course covers the fundamental design rules, regulations, and practices for ASME III and ASME B31 piping systems in nuclear power plants. The second part of the course provides a guide for the evaluation of degraded and non-conforming conditions through case studies, using ASME XI and the corresponding NRC regulations and precedent. The course concludes with a review of repair options for safety-related and non-safety piping systems and components.
