Executive SummaryThe next generation reactors in the United States (U.S.) are an opportunity for vendors to build new reactor technology with advanced Instrumentation and Control Systems (control rooms, distributed control systems, etc.). The advances made in the development of many current generation operating reactors in other parts of the world are being used in the design and construction of new plants. These new plants are expected to have fully integrated digital control rooms, computerized procedures, integrated surveillance testing with on-line monitoring and a major effort toward improving the operations and maintenance (O&M) and fault survivability of the overall systems. In addition the designs are also incorporating major improvements in the man-machine interface based on lessons learned in nuclear and other industries.Digital technology is available or emerging that can eliminate dependence on such legacy analog devices, with their attendant inaccuracies, limited reliability, and maintenance burdens. However, the nuclear industry has been slow to adopt these improved technologies due to lack of familiarity, licensing risk, and diversity concerns for safety significant applications. Without a resolution of this deficiency in the qualification basis for digital technologies, new plants and advanced designs may be constrained to continue reliance on legacy technologies for sensors and actuators rather than employ fully digital I&C systems.The recommendations presented in this report will be used as input to I&C research programming for the implementation of lessons learned during the early phases of new build both for large light water reactors (LWR) and also small modular reactors (SMR). This report is intended to support current research plans and provide user (vendor, owner-operator) input to the optimization of these research plans.v Acknowledgement
