  6. 6. 08/04/15 Jakeway, Maryrose 6 ProjectsProjects Eagle Incident Report •Created follow-up document for June 6th fire under waste treatment bridge. Power Sta South 900/265 psi Steam Pressure Reducing Valve (PRV) •Modeled S. PRV steam system. •Analyzed current design to determine nominal operational envelope. •Compared ideal conditions to 3/20/15 failure. •In progress: Operational Procedure Report.
  7. 7. Safety Valves on 265 # pipe Damage resulting from 3/20/15 • Learned how to perform an engineering and failure analysis. • First learn how and why things work. • Then look at a failure. • What fails? When? Why? How? • Knowing max steam flow rates at different pressures/ temperatures changes the operating envelope of the system and how the equipment will respond. • Develop a “model” of the system.
