Safety Case-oriented Assessment of Human-machine Interface for Npp I&c Systems
نویسندگان
چکیده
A safety assessment approach for human-machine interfaces (HMI) of Nuclear Power Plant (NPP) instrumentation and control systems (I&Cs) based on the Safety Case methodology is proposed. I&C assessment model is described taking into account human factor impact. Normative profile based on harmonization and standard requirements selection for choice of HMI safety assessment methods is developed. Ranking of major design principles of safe HMI is provided. Set of methods for comprehensive human machine interface safety assessment at life cycle stages is analyzed and adopted taking into consideration features of HMI safety attribute.

متن کاملError assessment in man-machine systems using the CREAM method and human-in-the-loop fault tree analysis
Background and Objectives: Despite contribution to catastrophic accidents, human errors have been generally ignored in the design of human-machine (HM) systems and the determination of the level of automation (LOA). This paper aims to develop a method to estimate the level of automation in the early stage of the design phase considering both human and machine performance. Methods: A quantita...
متن کاملt-WISE-BASED MULTI-FAULT INJECTION TECHNIQUE FOR THE VERIFICATION OF SAFETY CRITICAL I&C SYSTEMS
One well-known method for the verification and certification of NPP I&C and other safety critical systems is the fault injection technique (FIT). FIT is based on a design fault injection and vulnerability injection into the software code and the field-programmable gate array (FPGA) design or a physical fault injection into hardware modules. The requirements for FIT for safety critical applicati...

متن کاملDesign of an Integrated Operator Support System for Advanced NPP MCRs: Issues and Perspectives
A nuclear power plant (NPP) is operated by operators in a main control room (MCR). Usually, the operators in an MCR consist of three to five operators and the number of operators is different according to the plant type. The operators always monitor the plant status and manipulate the control devices when necessary. The MCR operators perform a supervisory role of information gathering, planning...
