Research Programs

Nuclear Energy Enabling Technologies (NEET) – Advanced Sensors and Instrumentation (ASI)• Cross-cutting new technologies in measurements, monitoring, control,

and human factors• Innovative methodologies• Communications and data transmission

Light Water Reactor Sustainability• Plant Modernization – digital technologies to modernize nuclear plant

operations and support, transforming the operating model from labor-centric to technology-centric to achieve performance improvement and cost reductions.

• Risk-Informed Systems Analysis (RISA) – new analytical, modeling, and simulation tools to increase plant margins and support risk-informed design and licensing issues.

Core Protection Processor

1. CCF unlikely for Analog Input Module (AIM), Component Interface module (CIM) and Isolator; CCF is assumed for all other devices.2. Grey boxes comprise Plant Control System (PCS). Controllers and servers are redundant; other components are not.3. Grey/brown boxes are non-safety. Brown box must be diverse from safety; brown box diversity from grey boxes is also preferred.4. All digital communication interfaces are fiber optic, except Maintenance Network in PCS and DAS, IT Network, and between D-VDU/I-VDU/Video Switch/I-VDU-P.5. All digital interfaces are bidirectional, except noted by arrows.6. Safety and PCS Networks are redundant; others are not.7. Audible devices for PCS and DAS alarms are in MCR.8. denotes hardwires; others are digital data communication.
