  1. VCSNS Benchmark Dose Rate • Average dose rate from 8 locations • All locations are general area dose rates around the bottom of the RCS loops • No contact or 12” measurements are used • Measurements are best when using the stored dose rate data from electronic dosimeters

  2. History of Benchmark Dose Rate • All outages prior to RF11 HP and Chem used gut feel to decide when RCPs secured, • OR Operations and Outage Management decided for them • Wanted analytical justification to run RCPs as long as possible. • Started with 14 pts general area in loops • 80+% of plant dose came from loops during outage

  3. Benchmark Monitoring Locations
