Emergency Service Water Piping


Evaluation of ‘retired’ nuclear service water piping to test ID corrosion rate system accuracy using different inspection intervals. Plan is to use mass screening tools to identify anomalies (cluster or point) and monitor vs. replace.


ESW Piping

  • 36” Sch. std. (.375”)
  • Selected existing ID pits, used dremel tool to “mimic” corrosion rate

Product Used

smartPIMS LT Cellular

  • smartPIMS LT Cellular w/ 2 dual element probes temporarily attached at identified “low spots” on ESW pipe
  • Monitoring interval: 1 minute
  • Data is displaced in webPIMS (seen below) for trending & A-scan analysis
