Exciting Time for Nuclear Industry – Operating Plants 436 operating plants worldwide with a total net installed capacity of ~370 GW(e) Several plants going through modernization to digital I&C and HSI throughout the world Many operating plants are extending or planning on extending their lifetimes Extended lifetimes –Will necessitate I&C and HSI modernization – and more than once, need to “design for replacement” –Provide the opportunities to gain substantial benefits from digital I&C and HSI

6 © 2009 Electric Power Research Institute, Inc. All rights reserved. Exciting Time for Nuclear Industry – New Plants New plants are being planned and built worldwide –New designs being certified –44 new plants currently under construction around the world –Many other plants being planned All new plants based on digital I&C and HSI technology

7 © 2009 Electric Power Research Institute, Inc. All rights reserved. Digital I&C and HSI Technology – Opportunities and Benefits Digital I&C and HSI address needs and brings significant opportunities and benefits for operating plants and new plants –Increase focus on plant and personnel reliability and productivity improvements –Increase benefits by taking advantage of capabilities of modern digital, HSI, information and communications technologies Enables an infrastructure that allows people to do their job better and faster with less likelihood of human error through the availability of the right information, to the right people, at the right time, in an easy to understand form

8 © 2009 Electric Power Research Institute, Inc. All rights reserved. Digital I&C and HSI Technology – Opportunities and Benefits (continued) Offers opportunities, when used effectively, for: –Increased functionality and productivity –Reduced operations and maintenance costs –Increased reliability and availability –Enhanced safety –Added flexibility and performance advantages Enhances knowledge capture and presentation Provides a technology that young people are familiar with and will be more attractive to bring them into the industry

Opportunities Through Use of Digital Sensors, data collection and transmission for more and better information On-line monitoring, diagnostics and prognostics for predictive maintenance and increased equipment reliability Simulation capabilities to support operations, design, engineering, maintenance and risk assessment Visualization capabilities to support decision making and usability Automation and intelligent agent aids to reduce workload and likelihood of human errors Human-system interfaces for facilitating well-informed situation awareness and decision-making Technology transfer and training for new technologies Operating experience providing lessons learned and best practices

10 © 2009 Electric Power Research Institute, Inc. All rights reserved. Challenges Business cases needed to get approval for new systems Technologies and systems must support safe and economic operation and reduce likelihood of human error Design, technical, implementation, and regulatory challenges must be overcome The proof of concept, pilot testing, and field implementation cycle must be shortened Training on new technologies Nuclear industry global, need as much common agreement on technical and regulatory requirements as possible Regulatory issues and guidance need to be addressed generically to reduce costs, risks and time required to license new plants and to modernize operating plants
