The capillary waveguide enables effective use of low powered lasers and rapid composition determination, for computation of required parameters to pre-adjust burner control based on incoming fuel. Tests on high pressure fuel streams show sub-second time response and better than one percent accuracy on natural gas fuel mixtures. Fuel composition and Wobbe constant values are provided at one second intervals or faster. The sensor, designed and constructed at NETL, is packaged for Class I Division 2 operations typical of gas turbine and boiler environments, and samples gas at up to 800 psig. Simultaneous determination of the hydrocarbons methane, ethane, and propane plus CO, CO2, H2O, H2, N2, and O2 are realized. The capillary waveguide permits use of miniature spectrometers and laser power of less than 100 mW. The capillary dimensions of 1 m length and 300 μm ID also enable a full sample exchange in 0.4 s or less at 5 psig pressure differential, which allows a fast response to changes in sample composition. Sensor operation under field operation conditions will be reported.","PeriodicalId":170653,"journal":{"name":"2012 Future of Instrumentation International Workshop (FIIW) Proceedings","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124716032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

International application of calibration monitoring has shown that sensors may operate for longer periods within calibration tolerances. This issue is expected to also be important as the United States looks to the next generation of reactor designs (such as small modular reactors and advanced reactor concepts), given the anticipated longer refueling cycles, proposed advanced sensors, and digital instrumentation and control systems. Online monitoring (OLM) can be employed to identify those sensors that require calibration, allowing for calibration of only those sensors that need it. The U.S. Nuclear Regulatory Commission (NRC) accepted the general concept of OLM for sensor calibration monitoring in 2000, but no U.S. plants have been granted the necessary license amendment to apply it. This paper summarizes a recent state-of-the-art assessment of online calibration monitoring in the nuclear power industry, including sensors, calibration practice, and OLM algorithms. This assessment identifies key research needs and gaps that prohibit integration of the NRC-approved online calibration monitoring system in the U.S. nuclear power industry. Several technical needs were identified, including an understanding of the impacts of sensor degradation on measurements for both conventional and emerging sensors; the quantification of uncertainty in online calibration assessment; determination of calibration acceptance criteria and quantification of the effect of acceptance criteria variability on system performance; and assessment of the feasibility of using virtual sensor estimates to replace identified faulty sensors in order to extend operation to the next convenient maintenance opportunity.","PeriodicalId":170653,"journal":{"name":"2012 Future of Instrumentation International Workshop (FIIW) Proceedings","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114489541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are numerous instances of original vintage equipment still installed and operating in these plants. This absence of modernization is due to many factors including the reliability of the existing equipment, lack of confidence and operating experience of digital systems, funding considerations, and regulatory concerns. There are however several successful instances of plant upgrades providing enhanced power output, efficiency, safety, and monitoring capabilities. With these successes, other technologies that can provide a benefit to the nuclear power industry will begin to gain acceptance. Wireless is one such technology that can find widespread use. Wireless technology has and will continue to face many perceived obstacles for implementation including cyber security, reliability, return on investment, and electromagnetic compatibility. Another issue that will arise with an expansion of wireless installations will be wireless coexistence. These concerns have been addressed by several utilities that have implemented wireless devices at various levels. However, nuclear power plants are typically slow to adopt cutting-edge technologies. Therefore, the advanced wireless protocols and sensor devices being developed today and in the near future will have to provide sufficient justification to address the implementation concerns. The two areas that will be difficult to address are electromagnetic compatibility and wireless coexistence. There is currently minimal guidance for the nuclear utilities with respect to either of these issues as they relate to wireless technology. Several organizations have and continue to perform research in these areas for the nuclear industry but further work is necessary to fully understand and address the real concerns.","PeriodicalId":170653,"journal":{"name":"2012 Future of Instrumentation International Workshop (FIIW) Proceedings","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124158545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It typically involves the sampling of multiple analog signals, and converting them into digital formats so that they can be processed. DAQ systems also involve microprocessors, microcontrollers, digital signal processing, and/or storage devices. Many multi-channel DAQs, which utilize some sort of processing for simultaneous input channels, are found in various applications. In this research, for heterogeneous multichannel signals, different sampling rates are identified for each channel, and optimized for best data quality with minimal storage requirement. Accordingly, power consumption and transmission times can be reduced. The fidelity of the proposed Scheduler-on-Chip (SchoC) is increased by using reconfigurable chip technology, where flexibility, concurrency, speed and reconfiguration can be achieved in hardware. Therefore, SchoC can be utilized in various real world applications especially hazardous environments, or isolated areas, for remote architecture reconfiguration, while keeping the cost of the device low. Performance evaluations show that the speed of the proposed SchoC is 24% faster than a comparable software-based scheduler. The proposed SchoC reduces the amount of data being acquired by 59%, which in turn decreases memory requirements.","PeriodicalId":170653,"journal":{"name":"2012 Future of Instrumentation International Workshop (FIIW) Proceedings","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128029439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
