Plant Information Model (PIM)

A Knowledge-centric Plant Information Model is a semantically organized set of interlinked facility information, relationships, rules and knowledge frameworks that collectively form digital representations of the plant throughout its life cycle

Plant Information Model (PIM) for the Plant Lifecycle

Design Construction Commissioning Operations and

Maintenance Long term Operation

Decommissioning

- Design specifications

- Design requirements

- Design changes

- As built drawings and specifications

- Design changes to Structures, Systems and Components

- Construction experience

- Testing and validation

- Design changes based on commissioning feedback

- Commissioning experience

- Design changes from operation feedback

- Operation experience

- Operation and Maintenance policies/procedures

- Major design changes to plant Structures, Systems and Components to improve performance and safety

- Data and experiences

Plant Information Model Captures the Information as the Plant Moves Through Lifecycles ( ~ 100 Years)

Work in Progress

- Semantic Technologies and their Application to Nuclear Knowledge Management

- Approaches & Guidelines of Taxonomy Development & Management in the

Nuclear Sector

- Application of Plant Information Models to Support and Manage Design -

Knowledge throughout the NPP Life Cycle

- Managing Nuclear Design Knowledge over the Life Cycle-Stakeholder

perspectives, challenges and approaches;

- Approaches to Lifecycle Management of Technical and Design - Requirements

Specifications for Nuclear Facilities

- Current Practices in the Management of design, manufacturing, construction and

commissioning information and knowledge during New Build Projects;

Conclusions

• Lifecycle perspective for Knowledge Management is an important requirement for safe, economical and reliable performance of NPPs

• Safety and business objectives should be drivers for this initiative

• IT enabled digital technologies like Plant Information Models ( PIM) play a key role in this process
