Steam and water analysis system (SWAS) [1] is a system dedicated to the analysis of steam or water.In power stations, it is usually used to analyze boiler steam and water to ensure the water used to generate electricity is clean from impurities which can cause corrosion to any metallic surface, such as in boiler and turbine.
IEC 60987 Nuclear power plants – Instrumentation and control important to safety – Hardware design requirements for computer-based systems; IEC 60988 Nuclear power plants – Instrumentation important to safety – Acoustic monitoring systems for detection of loose parts: characteristics, design criteria and operational procedures
The purpose of the Instrumentation Course is to provide the student, Power Plant Instrumentation Specialist, with skills and knowledge in the methods and techniques necessary to safely perform troubleshooting, testing, maintenance, and repair of instrumentation systems and components used on electrical power generation and distribution equipment.
An outline of key instrumentation is shown on Process Flow Diagrams (PFD) which indicate the principal equipment and the flow of fluids in the plant. Piping and Instrumentation Diagrams (P&ID) provide details of all the equipment (vessels, pumps, etc), piping and instrumentation on the plant in a symbolic and diagrammatic form.
1924 – Lester uses radiography to examine castings to be installed in a Boston Edison Company steam pressure power plant. 1926 – The first electromagnetic eddy current instrument is available to measure material thicknesses. 1927-1928 – Magnetic induction system to detect flaws in railroad track developed by Dr. Elmer Sperry and H.C. Drake.
The term “power system” describes the collection of devices that make up the physical systems that generate, transmit, and distribute power. The term “instrumentation and control (I&C) system” refers to the collection of devices that monitor, control, and protect the power system. Many power-system automation are monitored by SCADA.
[5] May 15, 1996: Lowering water levels around the nuclear fuel in unit 3 [7] reactor's core prompt a shut down at Dresden Generating Station and placement on the NRC's "watch list" that merit closer scrutiny by regulators. Dresden was on the NRC watch list six out of nine years between 1987 and 1996, longer than any of the 70 other operating ...
The PHA is in turn based on a hazard identification exercise. In the process industries (oil and gas production, refineries, chemical plants, etc.), this exercise is usually a hazard and operability study (HAZOP). The HAZOP usually identifies not only the process hazards of a plant (such as release of hazardous materials due to the process ...
