Nuclear Plants’ Challenge - Make
Significant Contributions Worldwide
• Maintain existing and develop new cost-effective
electricity generating plants
• Reduce production of CO2 and other “greenhouse” gases
by electricity generating plants to contribute to the
successful resolution of the challenges of global warming
– Technology scenarios have been analyzed for the
United States
– No one technology can carry the load of meeting
electricity demands and lower emissions – nuclear
plants must play a significant role

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

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

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

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

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

Technical Working Group on Nuclear
Power Plant Control and Instrumentation
• Members represent 19 countries
• Exchange information on national and international I&C
programs in nuclear power plants
• Advise the IAEA and give recommendations on future
activities related to NPP I&C
• Opportunity to recommend activities that will help:
– Maintain and enhance plant safety
– Improve plant and human performance
– Enable digital system implementation
– Capture and transfer expertise
– Provide large scale cost-effective electricity
