WTEC panel report on European nuclear instrumentation and controls

Control and instrumentation systems might be called the 'brain' and 'senses' of a nuclear power plant. As such they become the key elements in the integrated operation of these plants. Recent developments in digital equipment have allowed a dramatic change in the design of these instrument and control (I&C) systems. New designs are evolving with cathode ray tube (CRT)-based control rooms, more automation, and better logical information for the human operators. As these new advanced systems are developed, various decisions must be made about the degree of automation and the human-to-machine interface. Different stages of the development of control automation and of advanced digital systems can be found in various countries. The purpose of this technology assessment is to make a comparative evaluation of the control and instrumentation systems that are being used for commercial nuclear power plants in Europe and the United States. This study is limited to pressurized water reactors (PWR's). Part of the evaluation includes comparisons with a previous similar study assessing Japanese technology

Helicopter Flight Operational Quality Assurance (HFOQA): Development of HFOQA Analysis Software

Flight Operational Quality Assurance (FOQA), or Flight Data Monitoring (FDM), has benefited flight safety in both fixed-wing and helicopter operations. The relative youth of FOQA programs has resulted in their minimal application among the helicopter fleets of the world; thus, Helicopter FOQA (HFOQA) has merited consolidation and expansion. This mixed methods design developed HFOQA analysis software via a blend of the qualitative data from helicopter and FOQA experts with quantitative data represented by a sample of de-identified digital flight data from 1,014 helicopter flights. Development of the software emphasized three domains of interest: (a) helicopter flight phases; (b) helicopter operational and maintenance events; and (c) helicopter event-related and safety/efficiency flight profile measurements. This study\u27s resultant HFOQA analysis software has direct application to multifaceted helicopter operations (Emergency Medical Services [EMS], sightseeing, military, and others), and, in fact, has been utilized by an offshore helicopter operator in its daily operations

Developing Modified ADS-33D Helicopter Maneuvers for the Shipboard Environment

The Office of the Secretary of Defense chartered the Joint Shipboard Helicopter Integration Process (JSHIP), Joint Test and Evaluation (JT&E) Program to improve Joint interoperability between U.S. Navy ships and U.S. Army/Air Force helicopters. One effort of the JSHIP JT&E Program was to improve the modeling and simulation tools and fidelity levels associated with conducting Joint shipboard helicopter operations, for both testing agencies and operational users. The UH-60A helicopter and the LHA class ship were identified as the highest priority helicopter-ship pair for operational forces and also allowed JSHIP to enhance models that currently existed. Enhancing the visual model of an LHA ship was a primary effort for the research and testing community in order to accurately replicate the shipboard visual cueing environment. Evaluating enhanced visual models in a research flight simulator in order to reduce actual shipboard flight testing or expand wind launch/recovery envelopes required the use of more aggressive and precise flight maneuvers than standard shipboard takeoffs and landings. The U.S. Army’s Aeronautical Design Standard 33D (ADS-33D) contained flight test industry accepted maneuvers of sufficient aggressiveness and precision, but were not designed for, or intended to be flown from the deck of a ship at sea. The methodology and procedure used to modify selected ADS-33D flight maneuvers so that they could safely be executed aboard an LHA class ship is presented in this thesis, along with the final maneuver descriptions, locations, and flight tolerances. The results of the shipboard test program and follow-on simulator assessment are not presented here, as they fall outside the scope of this thesis. However, conclusions from the at-sea flight tests relating to development of the modified ADS-33D were included. The flight test philosophy, methodology, and lessons learned while developing the modified ADS-33D maneuvers for the shipboard environment are the primary conclusions drawn

[GAS TURBINE FUEL AND AIR CONTROL SYSTEM]

Advancement in power generation has tended to enhance the ability in producing a more efficient power especially in mass power generation. In producing an efficient power generation, fuel consumption is one of the major criteria that need to be enhanced. Recent advance in fuel flow control have the potential for a significant impact on the design and performance of modern gas turbine engine. Fuel flow control has the potential to enhance mixing of fluids, modify wake behavior and reduce drag. The need ofdesigning a efficient gas turbine fuel and air flow control has drive the author to make a first step in designing and improving the gas turbine fuel and air control system. As been mentioned before this requirement in heavy power generation are much important in agreater living for main kind. From this study and design author will go in-depth in real application ofcontrol system design. The definition of fuel and air control system that author adopt here is the used of the small modification (especially in steps response) to change the decision making or fuel and air consumption for the existing gas turbine available. The design will be base onDIDATEC TGT 1,5KW gas turbine (UTP). The design will be done byreal time data and linear time invariant system, also theoretical formulation that will be studied by author for the improvement project. The improvement design that been done by the author will be the implementation ofFuzzy Logic system , where this implementation have shown atremendous improvement and benefit especially in real time application with ambiguous decision making system. Author also will analyze and design others conventional control system such as PID controller and also Leadlag compensator design. The design of system will be done with the help of MATLAB andSIMULINK software for comparison and system implementation

Models and evaluation of human-machine systems

"September 1993.""Prepared for: International Atomic Energy Association [sic], Wagramerstrasse 5, P. 0. Box 100 A-1400 Vienna, Austria."Part of appendix A and bibliography missingIncludes bibliographical referencesThe field of human-machine systems and human-machine interfaces is very multidisciplinary. We have to navigate between the knowledge waves brought by several areas of the human learning: cognitive psychology, artificial intelligence, philosophy, linguistics, ergonomy, control systems engineering, neurophysiology, sociology, computer sciences, among others. At the present moment, all these disciplines seek to be close each other to generate synergy. It is necessary to homogenize the different nomenclatures and to make that each one can benefit from the results and advances found in the other. Accidents like TMI, Chernobyl, Challenger, Bhopal, and others demonstrated that the human beings shall deal with complex systems that are created by the technological evolution more carefully. The great American writer Allan Bloom died recently wrote in his book 'The Closing of the American Mind' (1987) about the universities curriculum that are commonly separated in tight departments. This was a necessity of the industrial revolution that put emphasis in practical courses in order to graduate specialists in many fields. However, due the great complexity of our technological world, we feel the necessity to integrate again those disciplines that one day were separated to make possible their fast development. This Report is a modest trial to do this integration in a holistic way, trying to capture the best tendencies in those areas of the human learning mentioned in the first lines above. I expect that it can be useful to those professionals who, like me, would desire to build better human-machine systems in order to avoid those accidents also mentioned above
