• The Technical Review Groups (TRGs) were created to provide support to the NRC Operating Experience (OpE)

Program.

• Purpose of TRGs is to identify issues, negative trends, and recurrences and to glean OpE insights and lessons learned that could be applied to NRC programs.

• Lessons learned from Davis Besse (NRC failed to connect the dots and effectively apply OpE).

• Various NRC offices have representatives in the TRGs.

• There are currently 25 TRGs.

What TRGs Review 4

- OpE Comms

- Inspection Findings
