2. Definition of Obsolescence
Obsolete Equipment - “An item in plant service that is no longer manufactured or are otherwise difficult to procure and qualify.”
Source: INPO NX-1037 Revision 1, Obsolescence Program Guideline

3. Obsolescence in Nuclear
What does that mean to Nuclear Power?
Manufacturers are no longer making components required to maintain Plant
Plants are built with technologies from the 60’s and 70’s
License Renewal: How will obsolescence impact the plant for the next 20 years?
Average of 20% of installed plant equipment is obsolete

4. Obsolescence Challenges
Existing station workloads make it difficult to allocate resources to support proactive solution development
Daily challenges of operating the plant take precedence over Proactive Obsolescence Management
Obsolescence Is Not Going Away:
Obsolescence is growing by an average of 12,000 models per year

5. How does Obsolescence Affect Configuration?
Design
Requirements
Physical
Configuration
Documented
It Impacts All Pillars of the Configuration Triangle!

6. How does Obsolescence Affect Configuration?
Documented Configuration:
Do you know what in your plant is obsolete?
Design Requirements
When replacing obsolete components/parts with new ones, will you change the design requirements?
Physical Configuration
The plant may change when replacing an obsolete item with a new item

7. Tackling Obsolescence
Understand Its Impact
Industry Tools Available:
Proactive Obsolescence Management System (POMS)
RAPID/OIRD
Prioritize Challenges
Preventive Maintenance Forecaster (PM Forecaster)
Obsolescence Manager (OM)
Solve Challenges
Several Solution Options:
Surplus
Equivalency Evaluations
Design Changes
Reverse Engineer
Industry Tools Available
CMIS

8. Tackling Obsolescence
Understand Its Impact
The Industry has adopted POMS to identify obsolescence
POMS collects all installed equipment information from each site
Every year, all manufacturers of equipment is contacted to identify obsolescence
All U.S. Utilities are members of POMS

9. Understanding Obsolescence Impact
POMS Identified:
19% of Data Collected Un-Usable
Cannot contact a manufacturer called “%^&:”
15% of Results Incomplete
Model number insufficient to determine obsolescence
11% of Results Unidentifiable
Manufacturer could not recognize Model Number

10. Understanding Obsolescence Impact
What does this mean to Configuration Management?
Incorrect/Missing information in Enterprise Management systems could indicate a gap in Configuration Management

11. Configuration Challenges
Configuration Challenges discovered when trying to understand impact of obsolescence to plant
Master Equipment List’s Incomplete/Inaccurate
Missing Information
Manufacturer
Model Number
Equipment Details
Incomplete
Model Number Incomplete
Series Number listed
Site specific number scheme/code
OEM Not Identified
AE’s listed as OEM
Utility listed as OEM
Bill of Materials Incomplete

12. Addressing Configuration Data
Data Clean-Up
Review Design Requirements and Physical Configuration to identify what is installed and update Configuration Management Databases
Look at:
Purchase Orders
Work Order History
Drawings
Vendor Manuals
Design Changes
Equivalency Evaluations
Walk-Down: Review Nameplate data
Large Effort
Attack in phases: Critical Components first

13. Data Clean-Up Results:
Better data available to identify obsolescence challenges
Provides for better planning
Some Utilities require Configuration Change Management to modify this information

14. Configuration Changes
Be Cognizant of Obsolescence When Performing Configuration Changes
Do not “design-in” obsolescence
Digital Equipment
Does the OEM have a long term replacement plan?
Does my new design implement an obsolete item?
Consider Adding a Check in your design process to check for obsolescence before completing design changes

15. Configuration Changes
Post Implementation: Update Data Systems
Does your Configuration Change Process require Enterprise Database Updates before Change is complete?
Have you updated the Master Equipment List?
Have you updated the Bill of Materials?
Avoid future obsolescence challenges by clearly documenting current design changes

16. Configuration Changes
When Performing activities that impact configuration due to Obsolescence:
Consider a “design once, install many” approach
Replace all affected component locations with the same item (when possible)
Identify and satisfy “worst case” characteristics when replacing obsolete items across multiple systems
