OPG Exercise Unified Response After Action Review

December 2016

Project Summary

Following the completion of Exercise Unified Response 2014, Ontario Power Generation (OPG) requested ISR’s assistance in addressing the key findings and lessons learned as reported in the Exercise Unified Response After Action Report. As a result ISR’s highly experienced team was able to create new plans and procedures to help aid in OPG’s radiation surveillance, accident projection and dose control programs. In conjunction with the Province of Ontario, ISR developed a Radiation Survey Plan for all stages of response as well as a staff rotational plan for release and post-release phases of a severe accident. These plans were made by studying and understanding the procedures used at accidents at Fukushima Daiichi plant and adapting and improving on them for use at OPG.

Following the completion of Exercise Unified Response 2014, OPG requested ISRs assistance in addressing the key findings and lessons learned as reported in the Exercise Unified Response After Action Report. This included developing the following plans and procedures:

  • Corrective Action Plan – The Action Plan included a work breakdown structure to address in detail OPG related key findings.
  • Offsite Dose Control Plan – In conjunction with the Region of Durham and the Province of Ontario, ISR developed an Offsite Dose Control Plan for management of responder doses as a result of off-site response.
  • Offsite Dose Control Procedures – Following OPG approval of the Offsite Dose Control Plan, detailed Procedures for identified OPG staff positions off-site were developed.
  • Offsite Radiation Survey Plan – In conjunction with the Province of Ontario, ISR developed a Radiation Survey Plan for all stages of response.
  • Offsite Radiation Survey Procedures – Following OPG approval of the Radiation Survey Plan, ISR developed detailed procedures for OPG staff positions with a role in offsite survey.
  • Staff Rotation Plan – ISR Investigated the procedure used at the Fukushima Daiichi plant for the rotation of staff into/out of the nuclear power plant during the release to the environment and after the release had stopped. This was used to develop a plan for OPG staff rotation for the release and post-release phases of the severe accident.
  • Staff Rotation Procedures – Following OPG approval of the Staff Rotation Plan, ISR developed detailed procedures for OPG staff positions with a role in the rotation of OPG personnel on/off-site following a severe accident.
