Advanced Reactor Licensing: Experience with Digital I&C Technology in Evolutionary Plants
نویسنده
چکیده
This report presents the findings from a study of experience with digital instrumentation and controls (I&C) technology in evolutionary nuclear power plants. In particular, this study evaluated regulatory approaches employed by the international nuclear power community for licensing advanced l&C systems and identified lessons learned. The report (1) gives an overview of the modern l&C technologies employed at numerous evolutionary nuclear power plants, (2) identifies performance experience derived from those applications, (3) discusses regulatory processes employed and issues that have arisen, (4) captures lessons learned from performance and regulatory experience, (5) suggests anticipated issues that may arise from international near-term deployment of reactor concepts, and (6) offers conclusions and recommendations for potential activities to support advanced reactor licensing in the United States.

Technology-neutral Nuclear Power Plant Regulation: Implications of a Safety Goals- Driven Performance-based Regulation
This paper summarizes a study of the implications of a technology-neutral regulation for advanced nuclear power plant designs and proposes a predominately rationalist approach to future nuclear plant regulations. The current body of regulations has been developed and evolved over the past 50 years with consideration of the knowledge and incidents experienced from operation of the Light Water Re...
متن کاملLicensing and Deployment of Advanced Reactors
The deployment of advanced reactors of the type proposed for Generation IV will require a new strategy for licensing and demonstration. One of the requirements for NRC certification is that for technologies, for which there is not a regulatory history or an experience base, demonstration plants are a requirement. The current regulatory process as codified 10 CFR Parts 50, 51 and 52 has to be me...

The Technical Working Group on Nuclear Power Plant Control and Instrumentation (TWGNPPCI) of IAEA has been active in providing guidance for the I&C field in the form of technical documents and reports. This year the writing of a new TECDOC to address the challenges in the implementing and licensing digital I&C in nuclear power plants was initiated. This paper reports on discussions within this ...
متن کاملA Cyber Security Risk Assessment for the Design of I&c Systems in Nuclear Power Plants
The instrumentation and control (I&C) systems in nuclear power plants (NPPs) collect signals from sensors measuring plant parameters, integrate and evaluate sensor information, monitor plant performance, and generate signals to control plant devices for a safe operation of NPPs. Although the application of digital technology in industrial control systems (ICS) started a few decades ago, I&C sys...
