1. INPO Perspective of Industry CM Performance
Steve Nichols
Manager, Engineering and Configuration Management

2. Evaluating CM PERFORMANCE OBJECTIVE (CM.2)
Plant activities are conducted in a manner that maintains configuration control and operating and design margins.
PERFORMANCE OBJECTIVE (CM.3)
Processes used to maintain consistency of plant configuration, design, and licensing bases are clearly defined and are implemented properly. Changes to plant configuration and design and licensing bases are effectively analyzed, controlled, and implemented.

3. INPO Evaluation Results

4. CM Areas for Improvement

5. CM.2 AFI Issues
Caution tags for longstanding equipment conditions in lieu of modification process
Temporary shielding installations in place for years without engineering evaluation
No actions taken to resolve a nonconservative instrument setpoint for more than a year
Operability evaluations recorded basis of inputs and assumptions not well-supported

6. CM.2 Causes
Personnel are not sensitive to what constitutes a plant change resulting in unapproved changes
Management not sufficiently involved in the review and approval of operability evaluations
Expectations for addressing degraded and nonconforming conditions are not clearly established or reinforced

7. CM.3 AFI Issues
DC supply in-rush current for inverter too high for breaker
Engineers are not consistently accounting for field performance data, validating test acceptance criteria, and considering outstanding changes to design calculations
Engineering did not evaluate temporary changes to the plant before installation

8. CM.3 Causes
Incomplete design verification by the responsible engineer and reviewers due to, in part, ineffective engineering work management, prioritization and scheduling of major projects
Design engineers not fully addressing underlying causes of equipment problems in developing and implementing some important modifications
Management not reinforcing procedure constraints placed on temporary configuration changes

9. INPO Perspective
CM issues continue to impact plant performance
CM lessons learned vital to new plant designs
Continued focus important
