PUR1 - I&C Upgrade Technical Details November 6, 2015
Hardware Components Startup, Intermediate, and Power Range System Drive Assembly Interface Electronics RMS System Interface HVAC System Interface Makeup Water System Interface Trend Recorders Annunciator Elapsed Time Meter Indicator Lights Display Workstations Networking Hardware 2
Reactor Protection System Flow Chart Fission Chamber CIC UIC UIC Digital Power Range Channel 1 Digital Power Range Channel 2 Digital Power Range Channel 3 Digital Power Range Channel 4 RTP 3000 TAS Magnet Power Supply 1 Magnet Power Supply 2 Startup Intermediate Intermediate Power Range 3
Digital Power Range Monitors Vendor Requirements Major Attributes Modular Construction Versatile Applications Robust and Reliable Proven by Operation Experience Will have pulse processing and Campbell signal processing 4
Digital Power Range Monitors Features Necessary Cycle time of signal processing Analog & Binary output signals Linear or Logarithmic Digital parameters that are lockable 5
Digital Power Range Monitors Architecture Detector provides signal Signal is amplified by preamp if necessary Pulses filtered and discriminated Analog signal converted to digital Analog and binary signals can be sent to the RPS Binary outputs sent for non-safety applications (Scientific data) 6
Digital Power Range Monitors Must Be SIMPLE Continuous non-variable signal processing Predictable signal processing time Manageable software size No operating system No reliance on outside time keeping Easy to implement testing protocol Exterior systems cannot change parameters or setpoints (read-only) 7
Main Items To Address
Logic Diagram Overview Manual Trip Actions Cut Magnet Current External RMS System to provide slow scram Count rate, period, linear power level and safety power level are inputs to PLC Any one trip signal will cause a setback or scram 9
Redundancy Overview RTP 3000 TAS is a system critical piece of equipment Failure of processors will not affect the ability of the RSS to perform its function Each RTP 3000 TAS PLC I/O card is rated for SIL-3 operation Includes a significant number of features to identify or mitigate failures Console and Hallway scrams independent 10
Trips Overview Startup and Shutdown handled by the CIC and Fission Chamber Overpower trips handled by all detectors Rate trips handled by all detectors 11
Rod Drop Times Overview Any movement of rods or initiation of manual scrams are configured as Sequence of Events RTP 3000 TAS PLC time stamps each event to the nearest millisecond Full insertion (rod bottom indication) is another event Software will show time difference 12
Access Controls Overview Current requirement is for room access and operator key switch Post-upgrade will require room access, operator key switch, and computer access credentials 13
