6. Invensys System Platform and InTouch Implementations - DCPP • Project Services Department • Project Management and Project Engineering Services • Instrumentation & Control Obsolescence Management (ICOM) ProgramProject Manager Supervisor – Scott Patterson - Triconex Steering Committee Member • Project Administration and Implementation for I&C Long-Term Plan • Class 1 Systems – Tricon with InTouch Visualization • Class 2 Systems – Allen-Bradley (ControlLogix) DACS • Auxiliary Board – System Platform with InTouch • Primary Plant Computer (PPC) – System Platform with InTouch

7. Auxiliary Board Project • Auxiliary Board Operation • Plant Operators control the gathering, treatment, and discharge of hazardous waste products created during operation of the DCPP U1 and U2 power plants. • Liquid Radwaste System (LRW) collects and processes the radioactive liquid wastes generated during plant operation. • Gaseous Radwaste System (GRW) collects and processes the radioactive gaseous wastes generated during plant operation. • Chemical and Volume Control System (CVCS) collects and processes borated radioactive effluents from the Reactor Coolant System. • Reduces the activity to levels acceptable for discharge to the environment.

8. Auxiliary Board Project • Originally a Fluidic Logic controlled system • Discrete pneumatic NAND devices • Negative Logic • Components Obsolete in early 90’s • Control System lacking in Human Performance factors design • Piecemeal changes during construction and early years of operation
