This book was released on 1997-05-02 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nuclear industry and the U.S. Nuclear Regulatory Commission (USNRC) have been working for several years on the development of an adequate process to guide the replacement of aging analog monitoring and control instrumentation in nuclear power plants with modern digital instrumentation without introducing off-setting safety problems. This book identifies criteria for the USNRC's review and acceptance of digital applications in nuclear power plants. It focuses on eight areas: software quality assurance, common-mode software failure potential, systems aspects of digital instrumentation and control technology, human factors and human-machine interfaces, safety and reliability assessment methods, dedication of commercial off-the-shelf hardware and software, the case-by-case licensing process, and the adequacy of technical infrastructure.

Download or read book Digital Instrumentation and Control Systems for New and Existing Research Reactors written by IAEA and published by International Atomic Energy Agency. This book was released on 2021-04-27 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: IAEA work in the area of research reactor operation and maintenance is aimed at enhancing the capabilities of Member States to utilize good engineering and management practices to improve research reactor reliability and availability. In particular, the IAEA supports activities addressing ageing management of research reactor instrumentation and control (I&C) systems. The purpose of this publication is to provide engineering guidance on the design, and operational aspects of digital I&C systems for the refurbishment of existing facilities and for new research reactors. Key areas addressed include codes and standards applicability, licensing issues, dealing with the change in human-system interface from analogue to digital technology, software verification and validation activities, periodic testing and inspection, and configuration management. The publication contains technical descriptions and summaries of available digital systems that have been utilized in both new research reactor designs, and in the upgrading of older analogue safety and control systems. This guidance is foreseen for the broad spectrum of research reactors types existing today.

This book was released on 2012-12-06 with total page 866 pages. Available in PDF, EPUB and Kindle. Book excerpt: This conference brought together experts from 15 countries to discuss application of Artificial Intelligence (AI) techniques to the nuclear industry. It was apparent from the meeting that even those active in the field were surprised at the extent of work and the progress made. There was a strong impression that application of this technology to nuclear power plants is inevitable. The benefits to improved operation, design, and safety are simply too significant to be ignored. This is a much different conclusion than might have been reached a few years ago when the technology was new and people were struggling to understand its significance. We believe that this meeting reflects a major turning point for the technology. It has moved from being a topic understood only by specialists to a situation where users are the most active people in the field. A broad array of innovative work is described from all of the participating countries. The activity in the u.s. is large and diverse. Although there is no nationally focussed policy for AI research in the U.S., many of these activities are reported here. Japan and France have a strong drive to integrate AI technology into their nuclear plants, and this is reflecteq in these proceedings.

This book was released on 1989 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control system designs for nuclear power plants are becoming more advanced through the use of digital technology and automation. This evolution is taking place because of: (1) the limitations in analog based control system performance and maintenance and availability and (2) the promise of significant improvement in plant operation and availability due to advances in digital and other control technologies. Digital retrofits of control systems in US nuclear plants are occurring now. Designs of control and protection systems for advanced LWRs are based on digital technology. The use of small inexpensive, fast, large-capacity computers in these designs is the first step of an evolutionary process described in this paper. Under the sponsorship of the US Department of Energy (DOE), Oak Ridge National Laboratory, Argonne National Laboratory, GE Nuclear Energy and several universities are performing research and development in the application of advances in control theory, software engineering, advanced computer architectures, artificial intelligence, and man-machine interface analysis to control system design. The target plant concept for the work described in this paper is the Power Reactor Inherently Safe Module reactor (PRISM), an advanced modular liquid metal reactor concept. This and other reactor designs which provide strong passive responses to operational upsets or accidents afford good opportunities to apply these advances in control technology. 18 refs., 5 figs.

Book excerpt: A method is described for the safe operation of a complex system such as a nuclear reactor using a digital computer. The computer is supplied with a data base containing a list of the safe state of the reactor and a list of operating instructions for achieving a safe state when the actual state of the reactor does not correspond to a listed safe state, the computer selects operating instructions to return the reactor to a safe state.

Available in PDF, EPUB and Kindle. Book excerpt: The High Temperature Lattice Test Reactor (HTLTR) at Richland, Washington, operates at temperatures up to 1000°C. Its low nuclear power requires a 384 kilowatt electrical heating system, that is divided into four circuits, to attain the high temperatures in the ten-foot cube of moderating graphite. This thesis describes the design and evaluation of an algorithm for digital computer control of the heating system. Design specifications for the algorithm were: (1) limited computer memory was available; (2) the ranges for the manipulated variables were limited and were different; (3) the temperature differences throughout the reactor were to be small; (4) the response was to be non-oscillatory; (5) there should be a small steady-state error; and (6) it was necessary to compensate for nonlinearities, The distributed nature of the heating system, its multitude of inputs and outputs, and its non-linearity over the operating range formed a process that was extremely difficult to describe without directly measuring the transfer function. Since the completion of the control program had to coincide with the completion of the reactor, the design of the algorithm could not wait until direct measurements on the system were made. A preliminary analysis of the reactor heating system showed that the design specifications could be met by using a discrete approximation to a continuous proportional-plus-integral controller as the framework around which to design the algorithm. The extensive logic and calculation power of the digital control computer provided the means to extend the basic form of the algorithm to meet the design specifications. A hybrid computer simulation of the heating system was designed for verifying the algorithm and for refining it to compensate for the interactions between circuits of the heating system. Important features of the simulation were: a program to optimize the control parameters by a "hill-climbing" method; and an operating program that allowed extensive changes in the digital portion of the simulation program while it was running. After the reactor was constructed, transfer functions for the heating system were obtained by step function tests to complete the hybrid simulation. In addition to amplitude scaling, time scaling by a factor of 3000 was necessary to obtain reasonable problem solution times for the control system. Extensive tests with the simulation showed that the first five design specifications were met, and that the system was stable. Extensive testing with the real system, which may take months to complete, is required to verify that the sixth specification will be met. However operating experience has shown that the feature of the algorithm to meet this specification will be necessary. General conclusions, that became obvious during the research on this thesis problem, were: simulation should be considered as a primary tool for the practical solution of complex design problems; and more development effort will be required to make advanced control concepts applicable to practical problems.
