| Electric Power Research Institute (EPRI) and the United States Department of Energy (DOE) under the Nuclear Energy Plant Optimization (NEPO) Program, is developing guidance for specifying and designing control rooms, remote shut-down panels, HSIs etc. The guidance is intended for application by utilities and suppliers of control room and HSI modernization. The guidance will facilitate specification, design, implementation, operations, maintenance, training, and licensing activities. This guidance will be used to reduce the likelihood of human errors and licensing risk, to gain maximum benefit of implemented technology, and to increase performance. The guidance is of five types. The first is planning guidance to help a utility develop its plant-specific control room operating concepts, its plant-specific endpoint vision for the control room, its migration path to achieve that endpoint vision, and its regulatory, licensing, and human factors program plans. The second is process guidance for general HSI design and integration, human factors engineering analyses, verification and validation, in-service monitoring processes, etc. The third is detailed human factors engineering guidance for control room and HSI technical areas. The fourth is guidance for licensing. The fifth is guidance for special topics related to operations and maintenance including training and simulation and safety monitoring and control guidance. Currently, the plan is that the overall guidelines will be made up of 34 guidelines on different topics of which 31 are completed. This may increase based on input from the project working group which includes 21 utilities as well as nuclear utility industry participants. Show
Guidelines for the modernization of nuclear power plant control room and human-system interfacesConference Naser, J; Fink, B; O'Hara, J; ... Several nuclear power plants are implementing instrumentation and control (I and C) modernization programs using digital equipment to address obsolescence issues and the need to improve plant performance, while maintaining high levels of safety. As an integral part of the I and C modernization program, the control room and other human-system interfaces (HSIs) are also being modernized. Utilities identified the need for guidance for control rooms and HSIs to support and improve personnel performance, reduce the likelihood of human errors, increase the productivity of the plant, and take effective advantage of the benefits that can be achieved with the new technology being implemented. A project, initially jointly funded by the Electric Power Research Inst. (EPRI) and the U.S. Dept. of Energy (US DOE) and later by EPRI alone, has developed guidance that will facilitate planning, specification, design, implementation, operations, maintenance, training, and licensing activities for control rooms and HSIs. Although this guidance was developed for modernization of operating plants, most of the guidelines apply to new plants as well. (authors) A Human Factors Engineering Process to Support Human-System Interface Design in Control Room ModernizationConference J.C., Joe,; R.L., Boring, The primary objective of the United States (U.S.) Department of Energy (DOE) Light Water Reactor Sustainability (LWRS) program is to sustain operation of the existing commercial nuclear power plants (NPPs) through a multi-pathway approach in conducting research and development (R&D). The Advanced Instrumentation, Information, and Control (II&C) System Technologies pathway conducts targeted R&D to address aging and reliability concerns with legacy instrumentation and control (I&C) and other information systems in existing U.S. NPPs. Control room modernization is an important part following this pathway, and human factors experts at Idaho National Laboratory (INL) have been involved in conducting R&D to support migration of new digital main control room (MCR) technologies from legacy analog and legacy digital I&C. This paper describes a human factors engineering (HFE) process that supports human-system interface (HSI) design in MCR modernization activities, particularly with migration of old digital to new digital I&C. The process described in this work is an expansion from the LWRS Report INL/EXT-16-38576, and is a requirements-driven approach that aligns with NUREG-0711 requirements. The work described builds upon the existing literature by adding more detail around key tasks and decisions to make when transitioning from HSI Design into Verification and Validation (V&V). The overall objective of this process is to inform HSI design and elicit specific, measurable, and achievable human factors criteria for new digital technologies. Upon following this process, utilities should have greater confidence with transitioning from HSI design into V&V. Are expenditures for materials that go directly into the creation of a product or service?Raw material expenses refer to the cost of the components that go into a final manufactured product. They are one of three expenses included in a manufacturer's cost of goods sold (COGS).
What type of control includes the anticipation and prevention of undesirable outcomes?The type of control that anticipates and prevents undesirable outcomes is: Preventive control.
