SIT Notes November 20 Public Meeting with Progress Energy Crystal River Containment Issues Talking Points:
The issue was identified on October 3. The NRC began a Special Inspection on October 13, and it is ongoing.
The purpose of the Special Inspection is to help the NRC better understand the issue and to independently assess Progress Energy's actions to address it.
Special Inspection Team includes 4 NRC inspectors and one contractor from Oak Ridge National Labs to provide added expertise and an outside look. All are degreed engineers (Civil and Mechanical).
4 have Professional Engineering licenses 2 have PhDs in Civil or Mechanical Engineering 75 years combined experience in applying concrete technology to nuclear applications 40 years combined experience in applying federal regulatory requirements to concrete containments The Special Inspection Team has the full support of the agency, and added technical resources as needed, to complete its objectives.
When the inspection is completed, the team plans to discuss the results at a public exit meeting in Crystal River, Florida.
