The ability of the instrument to complete measurements quickly and therefore process many samples is a key capability inherent in the system design [2]. Alignment and sample environment management are a time consuming and error prone process that has led to the development of automation in the control software operating the instrument. In fact, the original LR user interface, based on the Python scripting language, has been modularized and adapted to become the standard interface on many other instruments. A project to convert the original Python [3] implementation controlling the LR instrument into the modular version standardized at SNS was undertaken in the spring of 2012. The key features of automated sample alignment and robot-driven sample management system enable the instrument to reduce the manual labor required to prepare and execute observations, freeing up precious time for analysis and reporting activity. We present the modular PyDas control system [4], its implementation for the LR, and the lessons learned during the upgrade process.","PeriodicalId":170653,"journal":{"name":"2012 Future of Instrumentation International Workshop (FIIW) Proceedings","volume":"11 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":"117193792","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 is a whole-part test, so measurements taken in one place can indicate defects anywhere. It can be done quickly and requires minimal equipment. ART can be completely automated and make objective, quantitative judgments, eliminating human error. ART uses the fact that a part's physical structure causes it to have a distinct and unique set of characteristic frequencies. Every part with the same physical properties will have the same vibration properties, and any flaw will cause this vibration “fingerprint” to change. After a hammer impact, the characteristic frequencies of the part will be excited and every other frequency will quickly attenuate. By measuring the location and amplitude of several peaks of the part's dynamic response and comparing these values to a database of acceptable values, parts with defects can be quickly separated. ART can be used to find parts with out-of-tolerance dimensions, voids, and cracks, among other things. While the test will not determine the cause of rejection, with appropriate transducer sensitivity and software it can reliably find faults anywhere in a part. Currently Gassco is researching ways to use ART for in-line inspection of gas pipelines. ART is also being used on some automotive production lines to ensure 100% compliance with specifications. It is well-suited for quality assurance on drive train parts, piping sections, shielding and containment hardware, and other applications where fast and dependable flaw detection is critical.","PeriodicalId":170653,"journal":{"name":"2012 Future of Instrumentation International Workshop (FIIW) Proceedings","volume":"68 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":"132576637","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}

Some sites are even forced into living with a reactive maintenance strategy for all but the most critical systems. This typically leads to significant expense through costly downtime and component unavailability. Advancements in wireless technology have resulted in the implementation of measurement devices on some important systems that have alleviated the condition monitoring and testing burden on maintenance personnel. Through research and development (R&D) sponsored by the Department of Energy (DOE) Small Business Innovation Research (SBIR) program, a wireless condition monitoring application has been identified inside the containment of a pressurized water reactor (PWR) that can benefit from the introduction of wireless technology. The application that has been selected is the use of wireless vibration sensors to monitor the condition of containment cooling fans. The host utility for this project is the Arkansas Nuclear One (ANO) power generating station. Due to the location of the fans within the containment building, maintenance personnel are prevented from manually collecting vibration data frequently enough (e.g., monthly) to determine the health of the equipment. Through the use of wireless sensors, data can be collected once a day to provide a more complete picture of the fans' health with advanced warning of a failing component. This paper will document the efforts of this project to deploy a wireless vibration system at ANO.","PeriodicalId":170653,"journal":{"name":"2012 Future of Instrumentation International Workshop (FIIW) Proceedings","volume":"19 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":"117302634","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}
