Neutron radiation from CANDU Refurbishment Waste

Following identification of unanticipated neutron radiation from CANDU refurbishment waste, originating from waste associated with retube activities industry wide learning were achieved. Specific to Bruce Power we will look to present a high level overview of what transpired following identification of this hazard. The presentation will review;

• The notification, initial response and some lessons learned from the initial response
• The 3 pronged follow up we had to the event, with some high level detail on each;

  • Root cause investigation
  • Historic dosimetry assessment
  • Neutron production mechanism

• Future/ongoing actions being taken to address the issue
