  1. Automatic test equipment for C and I of compact LWR

    International Nuclear Information System (INIS)

    The C and I of compact LWR consist of a wide variety of electronic modules. Testing of these modules manually was found to be very cumbersome. To ease the testing of these modules, Automatic Test Equipments (ATE) were developed jointly by BARC and ECIL. This paper describes the design of two ATEs for testing 69 types of modules. A power supply ATE was developed for 43 types of power supply modules of type AC-AC, AC-DC, DC-DC and signal conditioning modules. A VME ATE was developed to test 26 types of VME bus based and other microcontroller based non-bussed modules. These ATEs are used for the automated black box testing of modules by feeding power and control inputs and checking the outputs without operator intervention. This paper describes the important considerations in design and the major design challenges. (author)

    Kim, Kor R.; Kim, Jae H.; Lee, Jae C.

    1996-06-01

    The selected weld areas of a reactor pressure vessel and adjacent piping are examined by the remote mechanized ultrasonic testing (MUT) equipment. Since the MUT equipment was purchased from southwest Research Institute (SwRI) in April 1985, 15 inservice inspections and 5 preservice inspections are performed with this MUT equipment. However due to the old age of the equipment and frequent movements to plant sites, the reliability of examination was recently decreased rapidly and it is very difficult to keep spare parts. In order to resolve these problems and to meet the strong request from plant sites, we intend to develop a new 3-axis control system including hardware and software. With this control system, we expect more efficient and reliable examination of the nozzle to shell weld areas, which is specified in ASME Code Section XI. The new 3-axis control system hardware and software were designed and development of our own control system, the advanced technologies of computer control mechanism were established and examination reliability of the nozzle to shell weld area was improved. With the development of our 3-axis control system for PaR ISI-2 computer control system, the reliability of nozzle to shell weld area examination has been improved. The established technologies from the development and detailed analysis of existing control system, are expected to be applied to the similar control systems in nuclear power plants.

  4. A programming system for a modular, flexible multicomputer system for the automatic control of automated test equipment

    International Nuclear Information System (INIS)

    The hardware used is operationally directed, consisting of largely self-functioning, micro-computing modules, combined together over a parallel systembus. For communication purposes between the modules and to synchronize their activities a multi microcomputing operating system is being developed which corresponds to the specific demands of computerized process-control (handling of real-word events under real-time conditions and operation of several parallel-running subprocesses). In order to program the user-specific test cycles a programming language has to be made available which can be coordinated with the operational range of specific test equipment in terms of commands and syntax and which can also easily be learned by operators having no specialised knowledge of data processing. With this objective in mind, a structural system is developed in this work, by the aid of which application-oriented programming languages can be implemented. The adaption of the programming system to a wide spectrum of applications in automatic testing is facilitated by its modular structure. The efficiency of the system is demonstrated by means of an industrial pilot-scale implementation. (orig./HP)

  7. Development of Automatic Ultrasonic Testing Equipment for Pressure-Retaining Studs and Bolts in Nuclear Power Plant

    International Nuclear Information System (INIS)

    Bolting degradation problems in primary coolant pressure boundary applications have become a major concern in the nuclear industry. In the bolts concerned, the failure mechanism was either corrosion wastage(loss of bolt diameter) or stress-corrosion cracking. Here the manual ultrasonic testing of RPV(Reactor Pressure Vessel) and RCP(Reactor Coolant Pump) stud has been performed. But it is difficult to detect indications because examiner can not exactly control the rotation angle and can not distinguish the indication from signals of bolt. In many cases, the critical sizes of damage depth are very small(1-2 mm order). At critical size, the crack tends to propagatecompletly through the bolt under stress, Resulting in total fracture. Automatic stud scanner for studs(bolts) was developed because the precise measurement of bolt diameter is required in this circumstance. By use of this scanner, the rotation angle of probe was exactly controlled and the exposure time of radiations was reduced

    A vibration welding system includes vibration welding equipment having a welding horn and anvil, a host device, a check station, and a robot. The robot moves the horn and anvil via an arm to the check station. Sensors, e.g., temperature sensors, are positioned with respect to the welding equipment. Additional sensors are positioned with respect to the check station, including a pressure-sensitive array. The host device, which monitors a condition of the welding equipment, measures signals via the sensors positioned with respect to the welding equipment when the horn is actively forming a weld. The robot moves the horn and anvil to the check station, activates the check station sensors at the check station, and determines a condition of the welding equipment by processing the received signals. Acoustic, force, temperature, displacement, amplitude, and/or attitude/gyroscopic sensors may be used.

    2014-04-01

    Full Text Available Digital circuits complexity and density are increasing and at the same time it should have more quality and reliability. It leads with high test costs and makes the validation more complex. The main aim is to develop a complete behavioral fault simulation and automatic test pattern generation (ATPG system for digital circuits modeled in verilog and VHDL. An integrated Automatic Test Generation (ATG and Automatic Test Executing/Equipment (ATE system for complex boards is developed here. An approach to use memristors (resistors with memory in programmable analog circuits. The Main idea consists in a circuit design in which low voltages are applied to memristors during their operation as analog circuit elements and high voltages are used to program the memristor’s states. This way, as it was demonstrated in recent experiments, the state of memristors does not essentially change during analog mode operation. As an example of our approach, we have built several programmable analog circuits demonstrating memristor -based programming of threshold, gain and frequency. In these circuits the role of memristor is played by a memristor emulator developed by us. A multiplexer is developed to generate a class of minimum transition sequences. The entire hardware is realized as digital logical circuits and the test results are simulated in Model sim software. The results of this research show that behavioral fault simulation will remain as a highly attractive alternative for the future generation of VLSI and system-on-chips (SoC.

    Considering the deficiency of the means for confirming the attribution of fault redundancy in the re-search of Automatic Testing System(ATS) , a fault-injection system has been proposed to study fault redundancyof automatic testing system through compurison. By means of a fault-imbeded environmental simulation, thefaults injected at the input level of the software are under test. These faults may induce inherent failure mode,thus bringing about unexpected output, and the anticipated goal of the test is attained. The fault injection con-sists of voltage signal generator, current signal generator and rear drive circuit which are specially developed,and the ATS can work regularly by means of software simulation. The experimental results indicate that the faultinjection system can find the deficiency of the automatic testing software, and identify the preference of fault re-dundancy. On the other hand, some soft deficiency never exposed before can be identified by analyzing the tes-ting results.

  16. Development of ultrasonic testing equipment incorporating electromagnetic acoustic transducer

    International Nuclear Information System (INIS)

    This paper describes an automatic flaw detection equipment and heat-resistant ultrasonic transducer for plate thickness measurement. The automatic flaw detection equipment is used during in-service inspection. It comprises an angle-beam electromagnetic acoustic transducer (EMAT), mounted on a vehicle, for scanning the pipe surface to be inspected. The EMAT functions without direct contact with the pipe surface through a coupling liquid, the vehicle does not require a guide track installed on the pipe surface, since it is equipped with magnetic wheels that adhere to the pipe, permitting it to travel along the circumferential weld joint of a carbon steel pipe. Another heat-resistant ultrasonic transducer is a normal beam EMAT and is used during plant operation. As a result, the automatic flaw detection equipment could detect a 1 mm deep notch cut on a test piece of 25 mm thick carbon steel plate. The vehicle location accuracy on the piping was ±2 mm. The normal beam EMAT could measure the plate thickness, within ±0.3 mm accuracy for the range of plate thickness 4 mm to 12 mm at 300degC. (author)

    International Nuclear Information System (INIS)

    Safeguards demands have brought about the use of new, advanced equipment. These new systems are typically more complex than previous systems sometimes making use of dense circuitry and complex controls that can bring out previously unseen susceptibilities to various environmental conditions. In addition to possibly being susceptible to ambient conditions such as temperature and humidity, there may be a misunderstanding regarding the operational limitations of the equipment. Will a radiation detector respond to a moving source? Will other types of radiation overwhelm the response of the detector to the radiation of interest? Will the electronics survive or become incapacitated after exposure to radiation? These questions and others need to be addressed through the use of a systematic testing program. The program should not be used as a tool for criticism, but as a method of improving the reliability of equipment in the field and as a technique for improving the operation of the equipment. This document presents some of the information that was obtained at Oak Ridge National Laboratory where a series of tests were performed on various types of equipment with differing functions. Equipment tested included data transmission devices and radiation sensors. Tests performed included ionizing radiation to test for effects from interfering radiation and as a characterization tool for such things as response to moving sources. Other tests involved the use of non-ionizing radiation to determine whether interference could occur when equipment is exposed to radio frequency or magnetic field environments. The remaining tests were performed to establish whether susceptibilities exist when equipment is exposed to various temperature and humidity environments. Although more testing may be needed, the test methodologies used could provide a direction to future qualification plans

    2002-05-01

    It is critical to a spacecraft's mission success that flight equipment be properly qualified to its expected shock environment. Simulators of varying fidelity are often used to measure the shock levels during spacecraft shock tests. Pyroshock test data from a recent spacecraft separation test will be shown that illustrates how shock response spectra differ for avionics equipment simulators of both low and high fidelity. The effect of the simulator weight on the shock response will also be shown. Additionally, data showing the attenuation of pyroshock levels, including its reduction with distance and across joints will be discussed. This observed attenuation data generally supports the standard methodologies for predictions of shock attenuation.

  5. Equipment qualification testing - a practical approach

    International Nuclear Information System (INIS)

    When nuclear safety equipment is credited with a Required Safety Function it must properly perform that function to facilitate safe control and/or shutdown of the plant during a design basis accident. When such equipment is required to be environmentally (EQ) and/or seismically qualified (SQ) for safety related use in CANDU nuclear power plants, the preferred method of qualification is by type testing. The qualification testing process requires that the test specimen equipment be subjected to the aging stressors associated with the normal service conditions that it would experience during it's required qualified (or service) life. Following the aging process, the test specimen is in a condition representative of that in which it would be at the end of its service life in the plant. The test specimen is then subjected to a simulated accident during which it must satisfy performance requirements thereby demonstrating that it can perform its required safety function. The performance requirements specified for the qualification testing must be designed to ensure that satisfactory performance of the safety function is demonstrated during the qualification program. This paper provides descriptions of practical methods used in the deriving and satisfying of relevant performance requirements during the qualification testing of safety related equipment. (author)

  8. Lessons learned in testing of safeguards equipment

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency's (IAEA) Department of Safeguards uses complex instrumentation for the application of safeguards at nuclear facilities around the world. Often, this equipment is developed through cooperation with member state support programs because the Agency's requirements are unique and are not met by commercially available equipment. Before approving an instrument or system for routine inspection use, the IAEA subjects it to a series of tests designed to evaluate its reliability. In 2000, the IAEA began to observe operational failures in digital surveillance systems. In response to the observed failures, the IAEA worked with the equipment designer and manufacturer to determine the cause of failure. An action plan was developed to correct the performance issues and further test the systems to make sure that additional operational issues would not surface later. This paper addresses the steps taken to address operation issues related to digital image surveillance systems and the lessons learned during this process. (author)

  9. MATE-asizing existing test equipment

    Science.gov (United States)

    Novotny, R.

    MATE embodies the planned business approach of the Air Force for procuring test equipment, taking into account also a test system architecture and a set of standards to define interfaces between test system components. The procurement philosophy employed requires all interested system component suppliers to create components consistent with MATE requirements. The selected components must meet the testing requirements of a particular test system with the lowest projected Life Cycle Costs (LCC). The present investigation is concerned with the Test Modules and Test Module Adapters (TMAs). The test modules perform traditional stimulus and sensor test functions. Attention is given to major MATE test module requirements, the Control Interface Intermediate Language (CIIL), considerations regarding external vs internal TMA functions, LCC, and synchronization methods.

    On traditional demarcation turntable, the transmission and the extraction of the inertial integrated information usually depend on the multi-channel links, the tie cable as well as the gathering card based on ISA, PCI, PXI or VXI bus. However, the usability of equipment is significantly influenced by the turntable's big size, high cost, low test-efficiency, and restricted demarcation flow. In this paper, a new solution scheme is provided based on the information exchange platform of automated calibration & test equipment. It adopts the embedded system-on-chip design, communication protocol design, fault tolerance and work pattern recognition and many other technologies for automated, intelligent and precision of calibration. The automation calibration equipment with the new design do not need the processes such as resetting the counter, turning back to zero and implementing initialization after starting up, and this provides the technical supports for shortening the calibration and test time (from 4 hours to 1.5 hours), flexibly calibrating the test procedures, reducing the cost of turntable (12 slippery ring road reduced to 2), reduce the equipment size, and obtaining accurate integrated measurement information.%传统标定转台往往依靠设备内部多路滑环、连接电缆以及基于ISA、PCI、PXI或VXI总线的采集卡进行惯测组合信息的传输和提取,转台体积大、成本高、标定流程受限以及测试效率低等因素极大影响了设备的使用性,基于自动化标定测试设备的信息交互平台,采用了嵌入式片上系统设计、通信协议设计、容错处理以及工作模式识别等多项技术,为实现自动化、智能化以及精准化标定提供了新的解决方案,采用新方案设计的自动化标定设备启动后无需再进行计数清零、转位回零以及初始化处理,为缩短标定测试时问(由4h缩短到1.51h),灵活的进行标定测试走位以及流程编排,降低转台成本(12

This will help the IAEA ensure that the design specifications for the equipment are consistent with the location where the instrument will be used; E.125.4, 'DIS Design Limit Testing and Advise to Strengthen IAEA's Current Equipment Qualification Criteria' - Under this subtask, Wyle Laboratories and Quanterion Solutions will conduct SDIS design limit testing, including harsh environmental testing and accelerated aging, to determine the expected lifetime and produce a design limit report to include maximum operating environment vs. design limit analysis. Additionally, this task will include the development of a strengthened environmental qualification test plan and reliability and maintainability definition methodology for all safeguards equipment. The implementation of new equipment by the Department of Safeguards is costly. Expected costs associated with the implementation of equipment include capital costs, training and in some cases travel. The cost is dramatically increased when operational issues arise due to the costs of studying the issues, modifying and upgrading the equipment and additional travel. The U.S. Support Program believes that the IAEA's Division of Safeguards Technical Support (SGTS) must strengthen its equipment-testing program to ensure that the equipment it approves for inspection use is reliable and will not place additional burden on the Department of Safeguards' maintenance and inspection staff. The U.S. Support Program recognizes that SGTS already requires a series of fundamentally important and revealing tests, but we believe that additional tests should be added to the testing

  3. Evaluation of the applicability of the tube-type automatic fire extinguishing equipment to the cable fire

    International Nuclear Information System (INIS)

    According to the examination standards related to fire protection for commercial nuclear power reactors and the supplementary facilities issued by Nuclear Regulation Authority in June 2013, a tube-type automatic fire extinguishing system for the cable fire, so called Fire-Erase (FE) system, will be implemented as early warning fire detection and extinction system to mitigate the fire damage to the cable trays for the safe shutdown functions. Therefore, it is necessary to acquire the demonstrative data for fire-extinguishing performance of FE system with respect to the cable tray fire. In this report, the cable fire suppression tests under over-current condition (2000A class) in the horizontal and vertical orientation were executed using the non-heat resistant high voltage power cables and the full-scale cable trays equipped with metal lid covered with fire-resistant sheet to prevent the leakage of fire extinguishing agent, and the effectiveness of the FE system was confirmed.

  9. Defect Prevention and Detection in Software for Automated Test Equipment

    Energy Technology Data Exchange (ETDEWEB)

    E. Bean

    2006-11-30

    Software for automated test equipment can be tedious and monotonous making it just as error-prone as other software. Active defect prevention and detection are also important for test applications. Incomplete or unclear requirements, a cryptic syntax used for some test applications—especially script-based test sets, variability in syntax or structure, and changing requirements are among the problems encountered in one tester. Such problems are common to all software but can be particularly problematic in test equipment software intended to test another product. Each of these issues increases the probability of error injection during test application development. This report describes a test application development tool designed to address these issues and others for a particular piece of test equipment. By addressing these problems in the development environment, the tool has powerful built-in defect prevention and detection capabilities. Regular expressions are widely used in the development tool as a means of formally defining test equipment requirements for the test application and verifying conformance to those requirements. A novel means of using regular expressions to perform range checking was developed. A reduction in rework and increased productivity are the results. These capabilities are described along with lessons learned and their applicability to other test equipment software. The test application development tool, or “application builder”, is known as the PT3800 AM Creation, Revision and Archiving Tool (PACRAT).

  10. Automatic gamma-ray equipment for multiple soil physical properties measurements

    International Nuclear Information System (INIS)

    Determination of soil physical parameters is sometimes very laborious and time consuming. For instance, the soil water retention curve takes several weeks. Particle density by picnometer and granulometry (texture) by pipette method are laborious methods. Other parameters, such as bulk density and total porosity, are determined by gravimetric methods and depends on oven drying the samples for 24 hours. In order to help in the soil physical parameters determination we have developed automatic equipment based on the attenuation of a gamma-ray beam by soil samples. Two types of samples are analyzed: solid (undisturbed) and dispersed soil particles in water, allowing the measurement and estimation of the following parameters: Particle size distribution (measured); Retention curve (estimated by Arya and Paris (1981) method); Particle density (estimated from measured mass attenuation coefficient of the soil sample); Bulk density (measured); Total porosity (estimated); Water content (measured). Here we focus on the explanation of gamma-ray attenuation method to measure and estimate the soil physical parameters mentioned above. Each method will be presented in detail together with calibrations and practical applications

    The purpose of this study is to identify candidate Monitored Geologic Repository (MGR) surface waste handling equipment for development testing. This study will also identify strategies for performing the development tests. Development testing shall be implemented to support detail design and reduce design risks. Development testing shall be conducted to confirm design concepts, evaluate alternative design concepts, show the availability of needed technology, and provide design documentation. The candidate equipment will be selected from MGR surface waste handling equipment that is the responsibility of the Management and Operating Contractor (M and O) Surface Design Department. The equipment identified in this study is based on Viability Assessment (VA) design. The ''Monitored Geologic Repository Test and Evaluation Plan'' (MGR T and EP), Reference 5.1, was used as a basis for this study. The MGR T and EP reflects the extent of test planning and analysis that can be conducted, given the current status of the MGR requirements and latest VA design information. The MGR T and EP supports the appropriate sections in the license application (LA) in accordance with 10 CFR 60.2 1(c)(14). The MGR T and EP describes the following test activities: site characterization to confirm, by test and analysis, the suitability of the Yucca Mountain site for housing a geologic repository; development testing to investigate and document design concepts to reduce risk; qualification testing to verify equipment compliance with design requirements, specifications, and regulatory requirements; system testing to validate compliance with MGR requirements, which include the receipt, handling, retrieval, and disposal of waste; periodic performance testing to verify preclosure requirements and to demonstrate safe and reliable MGR operation; and performance confirmation modeling, testing, and analysis to verify adherence to postclosure regulatory requirements.

Both cases are outside the original concept of operations for ATML but are typical when integrating large heterogeneous systems with modular contributions from multiple disciplines.

  14. A compliance testing program for diagnostic X-ray equipment

    International Nuclear Information System (INIS)

    Compliance testing is nominally that part of a quality assurance program dealing with those aspects of X-ray equipment performance that are subject to radiation control legislation. Quality assurance programs for medical X-ray equipment should be an integral part of the quality culture in health care. However while major hospitals and individual medical centers may implement such programs with some diligence, much X-ray equipment can remain unappraised unless there is a comprehensive regulatory inspection program or some form of compulsion on the equipment owner to implement a testing program. Since the late 1950s all X-ray equipment in the State of Western Australia has been inspected by authorized officers acting on behalf of the Radiological Council, the regulatory authority responsible for administration of the State's Radiation Safety Act. However, economic constraints, coupled with increasing X-ray equipment numbers and a geographically large State have significantly affected the inspection rate. Data available from inspections demonstrate that regular compliance and performance checks are essential in order to ensure proper performance and to minimize unnecessary patient and operator dose. To ensure that diagnostic X-ray equipment complies with accepted standards and performance criteria, the regulatory authority introduced a compulsory compliance testing program for all medical, dental and chiropractic diagnostic X-ray equipment effective from 1 January 1997

  17. CFC and HFC recycling equipments: Test performances

    International Nuclear Information System (INIS)

    Actual regulatory conditions about ozone layer depleting chemicals set problems on their disposal and on the management of plants still using illegal CFCs. Anyway fluids that will replace CFCs (i.e. HFCs) will not be allowed to be spread into the atmosphere, due to their high costs and to the greenhouse effect. A viable solution would be the recovery, purification and recycle of contaminated fluids. ENEA (National Agency for New Technology, Energy and the Environment), in cooperation with ICF (Industria Componenti Frigoriferi) Company leader in the field of air refrigerating and conditioning, patented a device able to extract, to clean and to recycle CFC 12 and HFC 134a in the refrigerating systems. This paper presents experimental data from the qualification tests on a device performing the above mentioned operations regarding systems that use HFC 134a as process fluid

  18. Automatic type-curve matching for well test analysis

    Energy Technology Data Exchange (ETDEWEB)

    Abbaszadeh, M.; Kamal, M.M.

    1988-09-01

    This paper presents a general method for automatic well test interpretation. The method matches the field data with theoretical reservoir models using a constrained, nonlinear, least-squares regression technique coupled with numerical Laplace inversion of pressure-drawndown equations. Pressure gradients are computed by forward finite-difference approximations. Hence, reservoir models whose pressure gradients are difficult to obtain analytically can be readily included. Only equations for drawndown type curves of reservoir models are needed. Simulated pressure tests and actual field data are analyzed to illustrate the application of the method. The method reduces the time required to perform well test analysis and minimizes the subjectivity of interpretation.

  19. Environment Canada's oil spill response equipment test facility

    International Nuclear Information System (INIS)

    The Emergencies Engineering Division of Environment Canada has established an oil spill countermeasures test facility in Ottawa. This facility includes an indoor test tank equipped with a continuous water flow system capable of producing a current of over 1 m/s. Several programs are currently under way to test and evaluate new or existing designs for countermeasures equipment. Skimmers, barriers, sorbents, separators, and even bioremediation products may be tested at this facility to assess their overall performance. These programs give priority to concepts which are considered new and innovative. Equipment tested to date includes an acoustical barrier prototype, a weir skimmer, a sorbent boom, a flow-through barrier concept, and a novel centrifugal flotation separator. A project to study the extent to which viscosity and emulsions will affect the performance of each of seven general skimmer categories is scheduled to begin in July 1993

    2015-01-01

    This paper provides insight into the testing of three-phase equipment exposed to voltage sags caused by faults. The voltage sag recovers at the fault-current zeros, leading to a `discrete' voltage recovery, that is, the fault is cleared in different steps. In the literature, the most widespread classification divides `discrete' sags into 14 types. The authors study shows that it is generally sufficient to consider only five sag types for three-phase equipment, here called `time-invariant (TI)...

  3. Testing of the AP600 automatic depressurization system

    International Nuclear Information System (INIS)

    The Automatic Depressurization System (ADS) of the Westinghouse AP600 reactor will be used to provide controlled depressurization of the reactor coolant system (RCS). This will, in turn allow the initiation and long term operation of gravity driven cooling flow in the RCS. ADS tests were conducted at the VAPORE test facility in Casaccia, Italy through a Technical Cooperation Agreement between Westinghouse, ENEA, SOPREN/ANSALDO, and ENEL to produce data for the development and verification of computer codes to simulate the system. The test program also provided insights about the operation of valves supplied from various vendors that could be used in the AP600 ADS. The data gathered from the tests showed the ability of the ADS design to fulfill its function over the range of conditions expected in the AP600. The tests also demonstrated the abilities of gate and globe valves from several vendors to initiate and terminate an ADS blowdown as could be required in the AP600

  4. Investigation of possible methods for equipment self-tests in digital radiology

    International Nuclear Information System (INIS)

    Quality control in digital radiology can be time-consuming. Equipment self-tests may significantly decrease staff workload. The two most essential parameters for radiology systems are image quality and patient dose. Concerning patient dose, information on the dose-area product (DAP) values generally forms the basis for assessment of patient dose. DAP-values can be measured using a transmission ionisation chamber or calculated from equipment settings. In the present study, various image quality parameters were derived using a contrast-detail (C-D) phantom. The investigation included a computer-aided assessment of C-D images, which produced various parameters, and also parameters based upon scoring by human observers. In addition, another parameter was calculated from modulation transfer function (MTF) measurements. The automatically calculated parameters showed good correlation with human readings, although the number of X-ray systems studied is still limited. We propose a combined evaluation of DAP and automatically calculated C-D or MTF parameters for equipment self-tests. (authors)

  7. A computer program for testing equipment control and data acquisition

    CERN Document Server

    Mostaco-Guidolin, Luiz C B; Galvao, Ricardo M O

    2009-01-01

    The software application described in this work aims to help with one of the main issues in experimental physics, the automation of data acquisition and equipment control. This software application, designated as SCTE, was written in Perl and uses the SCPI language to communicate with test instruments. The communication goes through RS-232 port, also known as serial port, vastly available in current generation PCs and testing equipment. Although the RS-232 port has been used here, SCTE may be easily adapted to work with USB or other kind of ports. SCTE enables the simultaneous control of several test equipment of different kinds, like oscilloscopes and signal generators, in order to automate an entire experiment. This program has been used to calibrate a new set of devices for power determination, part of the Alfven wave heating system of the tokamak TCABR.

  13. Diagnostic x-ray equipment compliance and facility survey. Recommended procedures for equipment and facility testing

    International Nuclear Information System (INIS)

    The Radiation Protection Bureau has set out guidelines for the testing of diagnostic x-ray equipment and facilities. This guide provides information for the x-ray inspector, test engineer, technologist, medical physicist and any other person responsible for verifying the regulatory compliance or safety of diagnostic x-ray equipment and facilities. Diagnostic x-radiation is an essential part of present day medical practice. The largest contributor of irradiation to the general population comes from diagnostic x-radiation. Although individual irradiations are usually small, there is a concern of possible excess cancer risk when large populations are irradiated. Unnecessary irradiations to patients from radiological procedures can be significantly reduced with little or no decrease in the value of medical diagnostic information. This can be achieved by using well designed x-ray equipment which is installed, used and maintained by trained personnel, and by the adoption of standardized procedures. In general, when patient surface dose is reduced, there is a corresponding decrease in dose to x-ray equipment operators and other health care personnel. 2 tabs., 4 figs

  14. Reliability and maintainability data acquisition in equipment development tests

    International Nuclear Information System (INIS)

    The need for collection of reliability, maintainability, and availability data adds a new dimension to the data acquisition requirements of equipment development tests. This report describes the reliability and maintainability data that are considered necessary to ensure that sufficient and high quality data exist for a comprehensive, quantitative evaluation of equipment and system availability. These necessary data are presented as a set of data collection forms. Three data acquisition forms are discussed: an inventory and technical data form, which is filed by the design engineer when the design is finished or the equipment is received; an event report form, which is completed by the senior test operator at each shutdown; and a maintainability report, which is a collaborative effort between senior operators and lead engineers and is completed on restart. In addition, elements of a reliability, maintainability evaluation program are described. Emphasis is placed on the role of data, its storage, and use in such a program

  15. Reactor protection system with automatic self-testing and diagnostic

    International Nuclear Information System (INIS)

    A reactor protection system is disclosed having four divisions, with quad redundant sensors for each scram parameter providing input to four independent microprocessor-based electronic chassis. Each electronic chassis acquires the scram parameter data from its own sensor, digitizes the information, and then transmits the sensor reading to the other three electronic chassis via optical fibers. To increase system availability and reduce false scrams, the reactor protection system employs two levels of voting on a need for reactor scram. The electronic chassis perform software divisional data processing, vote 2/3 with spare based upon information from all four sensors, and send the divisional scram signals to the hardware logic panel, which performs a 2/4 division vote on whether or not to initiate a reactor scram. Each chassis makes a divisional scram decision based on data from all sensors. Automatic detection and discrimination against failed sensors allows the reactor protection system to automatically enter a known state when sensor failures occur. Cross communication of sensor readings allows comparison of four theoretically ''identical'' values. This permits identification of sensor errors such as drift or malfunction. A diagnostic request for service is issued for errant sensor data. Automated self test and diagnostic monitoring, sensor input through output relay logic, virtually eliminate the need for manual surveillance testing. This provides an ability for each division to cross-check all divisions and to sense failures of the hardware logic. 16 figs

    Directory of Open Access Journals (Sweden)

    Konstantinos Sagonas

    2012-10-01

    Full Text Available With web services already being key ingredients of modern web systems, automatic and easy-to-use but at the same time powerful and expressive testing frameworks for web services are increasingly important. Our work aims at fully automatic testing of web services: ideally the user only specifies properties that the web service is expected to satisfy, in the form of input-output relations, and the system handles all the rest. In this paper we present in detail the component which lies at the heart of this system: how the WSDL specification of a web service is used to automatically create test case generators that can be fed to PropEr, a property-based testing tool, to create structurally valid random test cases for its operations and check its responses. Although the process is fully automatic, our tool optionally allows the user to easily modify its output to either add semantic information to the generators or write properties that test for more involved functionality of the web services.

  19. IRIS safety system and equipment design verification test plan

    International Nuclear Information System (INIS)

    The International Reactor Innovative and Secure (IRIS) is an advanced, integral, light-water cooled reactor of medium generating capacity (335 MWe), geared at near term deployment (2012-2015). IRIS is an innovative design that features an integral reactor vessel that contains all the reactor coolant system components, including the steam generators, coolant pumps, pressurizer and heaters, and control rod drive mechanisms; in addition to the: typical core, internals, control rods and neutron reflector. Other IRIS innovations also include a small, high design pressure, spherical steel containment; and a simplified passive safety system concept and equipment features that derive from its unique 'safety-by-design' IM philosophy. The IRIS ('safety-by-design')TM approach not only improves safety, but it also reduces the overall cost by allowing a significant reduction and simplification in safety systems. Moreover, IRIS improved safety supports licensing the power plant without the need for off-site emergency response planning an objective which is part of the pre-application with NRC and is also is being pursued in collaboration with IAEA. The IRIS innovative integral reactor coolant system design, as well as its innovative ('safety-by-design')TM approach features, has resulted in the need for new safety analyses and new equipment design and qualification, in order to successfully license the plant. Therefore, the IRIS design team has developed a test plan that will provide the necessary data for safety analyses verification as well as the demonstration of equipment manufacturing feasibility and operation. This paper will present the 'IRIS Safety System and Equipment Design Verification Test Plan' which develops and confirms the operation of all the IRIS unique features, and includes component manufacturing feasibility tests, component separate effects tests, component qualification tests, and integral effects tests. These tests will also provide the data necessary to

    2008-08-01

    Full Text Available Due to the great variability of its mechanical properties, the rational use of lumber for structural purposes is directly conditioned to its grading. There are several techniques available for grading structural lumber. The most relevant one is the transverse vibration technique which obtained reliable results in non-destructive evaluation of lumber. The purpose of this work is to present the bases for the mechanical grading of lumber and the results of the calibration test of the frst transverse vibration equipment developed in Brazil. In this research 30 beams of cupiúba (Goupia glabra with nominal dimensions of 5 cm X 10 cm X 300 cm, were used. The tests were accomplished at the Wood and Timber Structures Laboratory (LaMEM of the University of São Paulo (USP. The results showed a strong correlation between the elasticity modulus measured by the static bending test and the one obtained with the transverse vibration equipment, showing the high reliability of the vibration method for the grading of structural lumber. A determination coeffcient (R² of 0.896 was obtained with the Brazilian equipment, showing that it can be used in the grading of lumber.

    2008-07-01

    Full Text Available SDRAM (Synchronous Dynamic Random Access Memory demand has grown exponentially since the 1980s, as a result of technological factors and new areas of application, particularly concerning communication and consumer electronics. The SDRAM market represented in 2007 c. 20% of the total semiconductor business and is seen as a strategic area, justifying private and public investment in the western and far-eastern economic communities. SDRAM test education is therefore an important subject, but very high purchase and maintenance costs keep test equipment beyond reach of most university test courses. This paper presents a pilot project addressing an SDRAM test education course developed jointly by Qimonda and the University of Porto (FEUP, where the company offers remote access to one if its Advantest SDRAM automatic test equipments. Access to this remote tester was embedded into the Moodle e-learning server that supports a new course entitled Electronic Systems Testing (TSEL, which is part of the Integrated Masters degree on Electrical and Computer Engineering at FEUP. The excellent feedback received from students encouraged us to extend this cooperation into an educational network, which is also introduced in this paper.

  2. Specification and acceptance testing of nuclear medicine equipment

    International Nuclear Information System (INIS)

    The purchase of nuclear medicine equipment is of prime importance in the operation of a clinical service. Failure to properly evaluate the potential uses of the instrumentation and the various operational characteristics of the equipment can often result in the purchase of inappropriate or inferior instruments. The magnitude of the purchase in terms of time and financial investments make it imperative that the purchase be approached in a systematic manner. Consideration of both the intended clinical functions and personnel requirements is important. It is necessary also to evaluate the ability of the equipment vendor to support the instrumentation after the purchase has been completed and the equipment installed in the clinical site. The desired specifications of the instrument characteristics should be stated in terms that can be verified by acceptance testing. The complexity of modern instrumentation and the sensitivity of it to the environment require the buyer to take into account the potential problems of controlling the temperature, humidity, and electrical power of the installation site. If properly and systematically approached, the purchase of new nuclear medicine instrumentation can result in the acquisition of a powerful diagnostic tool which will have a useful lifetime of many years. If not so approached, it may result in the expenditure of a large amount of money and personnel time without the concomitant return in useful clinical service. (author)

    2009-09-09

    Retrievals under current criteria require that approximately 2,000,000 gallons of double-shell tank (DST) waste storage space not be used to prevent creating new tanks that might be susceptible to buoyant displacement gas release events (BDGRE). New criteria are being evaluated, based on actual sludge properties, to potentially show that sludge wastes do not exhibit the same BDGRE risk. Implementation of the new criteria requires measurement of in situ waste shear strength. Cone penetrometers were judged the best equipment for measuring in situ shear strength and an A.P. van den berg Hyson 100 kN Light Weight Cone Penetrometer (CPT) was selected for evaluation. The CPT was procured and then evaluated at the Hanford Site Cold Test Facility. Evaluation demonstrated that the equipment with minor modification was suitable for use in Tank Farms.

    2013-07-01

    Full Text Available Automatic Test Pattern Generation (ATPG is one of the core problems in testing of digital circuits. ATPG algorithms based on Boolean Satisfiability (SAT turned out to be very powerful, due to great advances in the performance of satisfiability solvers for propositional logic in the last two decades. SAT-based ATPG clearly outperforms classical approaches especially for hard-to-detect faults. But its inaccessibility of structural information and don’t care, there exists the over-specification problem of input patterns. In this paper we present techniques to delve into an additional layer to make use of structural properties of the circuit and value justification relations to a generic SAT algorithm. It joins binary decision graphs (BDD and SAT techniques to improve the efficiency of ATPG. It makes a study of inexpensive reconvergent fanout analysis of circuit to gather information on the local signal correlation by using BDD learning, then uses the above learned information to restrict and focus the overall search space of SAT-based ATPG. The learning technique is effective and lightweight. Experimental results show the effectiveness of the approach.

    2004-02-01

    About one million gallons of acidic, hazardous, and radioactive sodium-bearing waste are stored in stainless steel tanks at the Idaho Nuclear Technology and Engineering Center (INTEC), which is a major operating facility of the Idaho National Engineering and Environmental Laboratory. Calcination at high-temperature conditions (600 C, with alumina nitrate and calcium nitrate chemical addition to the feed) is one of four options currently being considered by the Department of Energy for treatment of the remaining tank wastes. If calcination is selected for future processing of the sodium-bearing waste, it will be necessary to install new off-gas control equipment in the New Waste Calcining Facility (NWCF) to comply with the Maximum Achievable Control Technology (MACT) standards for hazardous waste combustors and incinerators. This will require, as a minimum, installing a carbon bed to reduce mercury emissions from their current level of up to 7,500 to <45 {micro}g/dscm, and a staged combustor to reduce unburned kerosene fuel in the off-gas discharge to <100 ppm CO and <10 ppm hydrocarbons. The staged combustor will also reduce NOx concentrations of about 35,000 ppm by 90-95%. A pilot-plant calcination test was completed in a newly constructed 15-cm diameter calciner vessel. The pilot-plant facility was equipped with a prototype MACT off-gas control system, including a highly efficient cyclone separator and off-gas quench/venturi scrubber for particulate removal, a staged combustor for unburned hydrocarbon and NOx destruction, and a packed activated carbon bed for mercury removal and residual chloride capture. Pilot-plant testing was performed during a 50-hour system operability test January 14-16, followed by a 100-hour high-temperature calcination pilot-plant calcination run January 19-23. Two flowsheet blends were tested: a 50-hour test with an aluminum-to-alkali metal molar ratio (AAR) of 2.25, and a 50-hour test with an AAR of 1.75. Results of the testing

  10. Validation Testing for Automated Solubility Measurement Equipment Final Report

    Energy Technology Data Exchange (ETDEWEB)

    Lachut, J. S. [Washington River Protection Solutions LLC, Richland, WA (United States)

    2016-01-11

    Laboratory tests have been completed to test the validity of automated solubility measurement equipment using sodium nitrate and sodium chloride solutions (see test plan WRPS-1404441, “Validation Testing for Automated Solubility Measurement Equipment”). The sodium nitrate solution results were within 2-3% of the reference values, so the experiment is considered successful using the turbidity meter. The sodium chloride test was done by sight, as the turbidity meter did not work well using sodium chloride. For example, the “clear” turbidity reading was 53 FNU at 80 °C, 107 FNU at 55 °C, and 151 FNU at 20 °C. The sodium chloride did not work because it is granular and large; as the solution was stirred, the granules stayed to the outside of the reactor and just above the stir bar level, having little impact on the turbidity meter readings as the meter was aimed at the center of the solution. Also, the turbidity meter depth has an impact. The salt tends to remain near the stir bar level. If the meter is deeper in the slurry, it will read higher turbidity, and if the meter is raised higher in the slurry, it will read lower turbidity (possibly near zero) because it reads the “clear” part of the slurry. The sodium chloride solution results, as measured by sight rather than by turbidity instrument readings, were within 5-6% of the reference values.

  11. Analysis of the automatic depressurization system (ADS) tests for the AP600 design

    International Nuclear Information System (INIS)

    The AP600 is a Westinghouse advanced pressurized water reactor (PWR) designed with passive plant safety features that rely on natural driving forces, such as gravity, and natural circulation which allows significant simplification of the plant systems equipment and operation. As part of the passive safety concept, the AP600 utilizes an Automatic Depressurization System (ADS) to depressurize the Reactor Coolant System (RCS) allowing long-term gravity injection to be initiated and maintained for passive reflood and long term core cooling. The ADS design consists of four flow paths, two of which are connected to the top of the pressurizer and a flow path from each of the two RCS hot legs. During a postulated accident, the two flow paths from the hot legs discharge directly to containment. The two paths from the pressurizer discharge steam and/or water from the RCS into the In-containment Refueling Water Storage Tank (IRWST) through spargers located underwater where the steam is normally condensed with no increase in containment pressure or temperature. The ADS tests are one part of the planned AP600 Westinghouse test program for the passive core cooling system (PXS). The ADS tests are full-scale simulations of AP600 ADS components. The ADS tests provide dynamic performance data of the ADS for use in computer code validation and design verification

    1998-01-01

    In the Space Station Processing Facility, STS-88 Mission Specialists Sergei Krikalev, a Russian cosmonaut, and Jerry L. Ross check out equipment on the Unity connecting module, primary payload on the mission. The STS-88 crew members are participating in a Crew Equipment Interface Test (CEIT), familiarizing themselves with the orbiter's midbody and crew compartments. Scheduled for launch on Dec. 3, 1998, STS-88 will be the first Space Shuttle launch for the International Space Station. The Unity connecting module will be mated to the Russian-built Zarya control module, already on orbit after a November launch. Unity will have two Pressurized Mating Adapters (PMAs) attached and 1 stowage rack installed inside. PMA-1 will connect U.S. and Russian elements; PMA-2 will provide a Shuttle docking location. Eventually, Unity's six ports will provide connecting points for the Z1 truss exterior framework, U.S. lab, airlock, cupola, Node 3, and the Multi-Purpose Logistics Module, as well as the control module. Zarya is a self-supporting active vehicle, providing propulsive control capability and power through the early assembly stages. It provides fuel storage capability and a rendezvous and docking capability to the Service Module.

  13. Original equipment manufacturers (OEM) protective coating design basis Accident testing

    International Nuclear Information System (INIS)

    The United States Nuclear Regulatory Commission (USNRC) currently holds the position that 100 percent of design basis accident (DBA) unqualified coating materials located within a pressurised water reactor (PWR) containment will fail (dis-bond) during a DBA (e.g. loss of coolant, main steam line break) and may contribute to the emergency core cooling system (ECCS) sump debris source term. Electrical cabinets, small cranes, electric motors, pipe support components, and other miscellaneous equipment installed within US PWR containments are often coated by the original equipment manufacturers (OEM) using DBA unqualified coating materials (usually a standard shop oil based alkyd system). Little or no documented DBA test data currently exists concerning these OEM coatings. In support of the US industry efforts to resolve Generic Safety Issue 191, EPRI International, PSE Division (EPRI PSE) and the Nuclear Utility Coating Council (NUCC) are jointly conducting research to investigate the actual effect of PWR DBA environmental exposure on OEM coatings applied to components installed in US PWR containments. This paper will present details concerning the study. The EPRI/NUCC study, entitled, 'Unqualified OEM Coatings Testing', will be conducted during 2004 in four major steps: 1. conduct an industry-wide survey to determine which components in US PWR containments are normally coated with DBA-unqualified OEM coatings; 2. determine which of the components identified in Step 1 have been previously EQ tested, and review available EQ test data to determine the performance of the OEM coatings when exposed to DBA environments; 3. determine which of the components identified in Step 1 have not been previously EQ tested, and perform DBA testing on samples cut from actual OEM components in accordance with ASTM D3911-03 and ASTM D4082-02; and 4. publish the results of Steps 2 and 3 in two separate reports. The EPRI/NUCC study plan is described in this paper. Since the actual study will

  1. Meteorological testing and analysis of sampling equipment for wet deposition

    International Nuclear Information System (INIS)

    11 rain collector types for wet deposition were subjected to a field test. Two of the nine types were identically constructed. The following measured values were analyzed: amount of rainfall, electrical conductivity, pH value, Cl-, NO3-, SO4=, NH4+, Na+, K+, Ca++, Mg++, Fe, Pb, Cu, Cd. The analysis was restricted to rainfall. In a basic study structural and statistical analyses of precipitations were made in order to find out from which extent of intensity resp. rain volume per rainfall the precipitations are important for wet deposition. Some sensors required intensities of nearly 1 mm/h in order to recognize all rainfalls. In order to reach a better standardization of the measuring technique the funnel geometry should be standardized. The current technique is not suited for correctly registering the deposition which is connected with light and very light rainfall. It was found out in rinsing tests with diluted HNO3 that considerable amounts of trace metals accumulate at funnel walls and in headers, although the collecting device had been subjected to a thorough acid purification before. For the determination of the wet deposition of the trace metals problems arise if the samples are filtered and the filters are not analyzed. In that case particle-bound metals which are suspended in raindrops will not be registered. After comparing the equipment some of the devices were improved in order to eliminate known sources of contamination. (orig./KW)

  2. Measuring and test equipment control through bar-code technology

    International Nuclear Information System (INIS)

    Over the past several years, the use, tracking, and documentation of measuring and test equipment (M ampersand TE) has become a major issue. New regulations are forcing companies to develop new policies for providing use history, traceability, and accountability of M ampersand TE. This paper discusses how the Fast Flux Test Facility (FFTF), operated by Westinghouse Hanford Company and located at the Hanford site in Rich- land, Washington, overcame these obstacles by using a computerized system exercising bar-code technology. A data base was developed to identify M ampersand TE containing 33 separate fields, such as manufacturer, model, range, bar-code number, and other pertinent information. A bar-code label was attached to each piece of M ampersand TE. A second data base was created to identify the employee using the M ampersand TE. The fields contained pertinent user information such as name, location, and payroll number. Each employee's payroll number was bar coded and attached to the back of their identification badge. A computer program was developed to automate certain tasks previously performed and tracked by hand. Bar-code technology was combined with this computer program to control the input and distribution of information, eliminate common mistakes, electronically store information, and reduce the time required to check out the M ampersand TE for use

  3. Research on Object-oriented Software Testing Cases of Automatic Generation

    Directory of Open Access Journals (Sweden)

    Junli Zhang

    2013-11-01

    Full Text Available In the research on automatic generation of testing cases, there are different execution paths under drivers of different testing cases. The probability of these paths being executed is also different. For paths which are easy to be executed, more redundant testing case tend to be generated; But only fewer testing cases are generated for the control paths which are hard to be executed. Genetic algorithm can be used to instruct the automatic generation of testing cases. For the former paths, it can restrict the generation of these kinds of testing cases. On the contrary, the algorithm will encourage the generation of such testing cases as much as possible. So based on the study on the technology of path-oriented testing case automatic generation, the genetic algorithm is adopted to construct the process of automatic generation. According to the triggering path during the dynamic execution of program, the generated testing cases are separated into different equivalence class. The number of testing case is adjusted dynamicly by the fitness corresponding to the paths. The method can create a certain number of testing cases for each execution path to ensure the sufficiency. It also reduces redundant testing cases so it is an effective method for automatic generation of testing cases.

  10. Crack measurement: Development, testing and applications of an automatic image-based algorithm

    Science.gov (United States)

    Barazzetti, Luigi; Scaioni, Marco

    The paper presents an Image-based Method for Crack Analysis (IMCA) which is capable of processing a sequence of digital imagery to perform a twofold task: (i) the extraction of crack borders and the evaluation of its width across the longitudinal profile; (ii) the measurement of crack deformations (width, sliding and rotation). Here both problems are solved in 2-D, but an extension to 3-D is also addressed. The equipment needed to apply the method is made up of a digital camera (or a still video-camera in case a high frequency in data acquisition is necessary), an orientation frame which establishes the object reference system, a pair of signalized supports to be placed in a permanent way on both sides of the crack to compute deformations; however, permanent targets are mandatory only for case (ii). The measurement process is carried out in a fully automatic way, a fact also that makes this technique highly operational for unskilled people in engineering surveying or photogrammetry. The accuracy of the proposed method, evaluated in experimental tests adopting different consumer digital cameras, is about ± 5-20 μm, like the accuracy of most deformometers, but with the advantage of automation and of augmented achievable information; moreover, the image sequence can be archived and off-line measurements could be performed at any time.

    International Nuclear Information System (INIS)

    With the aim of enhancing the global competitiveness of instrumentation and control (I and C) systems for nuclear power plants, Toshiba has been making efforts to reduce the worker hours required for the testing of such systems and improve the quality of the tests. Display screen tests, which include many routine, repetitive tests and manual tests requiring a large number of operators to monitor multiple screen displays of the I and C system, are an essential element of the testing process. The introduction of automatic testing technologies is expected to substantially improve the efficiency of such display screen tests. We have now developed automatic testing technologies for display screen tests that can be applied without the need to change the I and C system. These technologies contribute to both the reduction of worker hours for testing and improvement of the quality of the tests. (author)

  3. Test of an automatic precision guidance system for cultivation implements

    International Nuclear Information System (INIS)

    By guiding implements accurately various field activities can be performed very precisely, such as row crumbling, band fertilizing, row spraying, drilling and hoeing. This means that no inputs are applied at places where they are not needed or would cause undue pollution of the environment. In the work reported here, the accuracy of a laser guidance system was examined when a hoe was used. On a level and slightly pressed band of soil approximately 1 m wide and full-field length, three paper sheets were spread with dimensions of approximately 15 m × 1 m. These pieces of paper were placed at approximately 35, 120 and 220 m from the laser transmitter. The centre element of the hoe carried a writing device, suspended to allow free vertical movement, which produced traces on the paper of the true path followed by the implement. Automatic guidance of an agricultural implement mounted on a vehicle by means of a side-shift facility, proved to be accurate within an average of ±6 mm on a track length of 220 m on arable land.

  4. Quality audits of the remote-controlled automatically-driven gamma ray afterloading equipment used in brachytherapy in the Czech Republic

    International Nuclear Information System (INIS)

    To reach safety and precise application of ionisation radiation to patients Atomic act declares, in its Article no. 7, requirements for medical exposure. There are also given -among others -the demands to install the quality assurance programmes (QA) for medical actions and functions. Since 1997, when the act has been adopted, a set of five Recommendations of State Office for Nuclear Safety (SONS ) for radiotherapy has been prepared to instruct users how to prepare quality control system (i.e. system of tests required by of the regulation no.184/1997 Sb. -acceptance, status and constancy tests) for main types of sources used in radiotherapy for treatment of the patients. Among them also the Recommendation on QA in brachytherapy has been issued by SONS in 1998. National Radiation Protection Institute (NRPI) has been performing the regular in situ quality audits in which the chosen parameters (which could seriously influence the dose to the patients -i.e. absorbed dose, main geometrical and radiation parameters etc ) are independently checked by the NRPI experts. System of Quality Audits on the sources used in teletherapy has been introduced in 1997 and at present time they are smoothly carried out according the SONS's demands. This work describes the process of installing of the Quality Audit system on brachytherapy. The work described here forms the only part of the activities, which have been carrying out by the department of dosimetry gamma and X-rays of NRPI to support supervisions of SONS in the field of radiation protection in radiotherapy .Quality audits in brachytherapy will extend the possibilities of NRPI. The Methods NRPI 43-01.30 prepared by NRPI could be used as documentation for all types of test which are at present time required by Czech legislation for the remote-controlled automatically-driven gamma-ray afterloading equipment used in brachytherapy.

  9. Automatically generated acceptance test: A software reliability experiment

    Science.gov (United States)

    Protzel, Peter W.

    1988-01-01

    This study presents results of a software reliability experiment investigating the feasibility of a new error detection method. The method can be used as an acceptance test and is solely based on empirical data about the behavior of internal states of a program. The experimental design uses the existing environment of a multi-version experiment previously conducted at the NASA Langley Research Center, in which the launch interceptor problem is used as a model. This allows the controlled experimental investigation of versions with well-known single and multiple faults, and the availability of an oracle permits the determination of the error detection performance of the test. Fault interaction phenomena are observed that have an amplifying effect on the number of error occurrences. Preliminary results indicate that all faults examined so far are detected by the acceptance test. This shows promise for further investigations, and for the employment of this test method on other applications.

  18. The introduction of compulsory compliance testing of medical diagnostic x-ray equipment in Western Australia

    International Nuclear Information System (INIS)

    Performance testing of medical diagnostic X-ray equipment can reveal equipment faults which, while not always clinically detectable, may contribute to reduced image quality and unnecessary radiation exposure of both patients and staff. Routine testing of such equipment is highly desirable to identify such faults and allows them to be rectified. The Radiological council of Western Australia is moving towards requiring compulsory compliance testing of all (new and existing) medical diagnostic X-ray equipment that all new mobile radiographic and new mammographic X-ray equipment be issued with a compliance test certificate as a prerequisite for registration. Workbooks which provide details of the tests required and recommended test methods have been prepared for medical radiographic (mobile and fixed), fluoroscopic and mammographic X-ray equipment. It is intended that future workbooks include details of the tests and methods for dental and computed tomography X-ray units. The workbooks are not limited to the compliance testing of items as specified in the Regulations, but include tests for other items such as film processing, darkrooms and image quality (for fluoroscopic equipment). Many of the workbook tests could be used within a regular quality assurance program for diagnostic X-ray equipment. Persons who conduct such compliance tests will need to be licensed and have all test certificates endorsed by a qualified expert. Suitable training and assessment of compliance testers will be required. Notification of such tests (including non-compliant items and corrective actions taken) will be required by the Radiological Council as a condition of equipment registration. 9 refs

  20. Seismic fragility capacity of equipment--horizontal shaft pump test

    International Nuclear Information System (INIS)

    The current seismic fragility capacity of horizontal shaft pump is 1.6 x 9.8 m/s2(1.6 g), which was decided from previous vibration tests and we believe that it must have sufficient margin. The purpose of fragility capacity test is to obtain realistic seismic fragility capacity of horizontal shaft pump by vibration tests. Reactor Building Closed Cooling Water (RCW) Pump was tested as a typical horizontal shaft pump, and then bearings and liner rings were tested as important parts to evaluate critical acceleration and dispersion. Regarding RCW pump test, no damage was found, though maximum input acceleration level was 6 x 9.8 m/s2 (6 g). Some kinds of bearings and liner rings were tested on the element test. Input load was based on seismic motion which was same with the RCW pump test, and maximum load was equivalent to over 20 times of design seismic acceleration. There was not significant damage that caused emergency stop of pump but degradation of surface roughness was found on some kinds of bearings. It would cause reduction of pump life, but such damage on bearings occurred under large seismic load condition that was equivalent to over 10 to 20 g force. Test results show that realistic fragility capacity of horizontal shaft pump would be at least four times as higher as current value which has been used for our seismic PSA. (authors)

    - Technical aspect · It is intended that digital I and C software have safety and reliability. Project results help the software to acquire license. Software verification technique, which results in this project, can be to use for digital NPP(Nuclear power plant) in the future. · This research introduces many meaningful results of verification on digital protection logic and suggests I and C software testing strategy. These results apply to verify nuclear fusion device, accelerator, nuclear waste management and nuclear medical device that require dependable software and high-reliable controller. Moreover, These can be used for military, medical or aerospace-related software. - Economical and industrial aspect · Since safety of digital I and C software is highly import, It is essential for the software to be verified. But verification and licence acquisition related to digital I and C software face high cost. This project gives economic profit to domestic economy by using introduced verification and testing technique instead of foreign technique. · The operation rate of NPP will rise, when NPP safety critical software is verified with intellectual V and V tool. It is expected that these software substitute safety-critical software that wholly depend on foreign. Consequently, the result of this project has high commercial value and the recognition of the software development works will be able to be spread to the industrial circles. - Social and cultural aspect People expect that nuclear power generation contributes to relieving environmental problems because that does not emit more harmful air pollution source than other power generations. To give more trust and expectation about nuclear power generation to our society, we should make people to believe that NPP is highly safe system. In that point of view, we can present high-reliable I and C proofed by intellectual V and V technique as evidence

  2. Reliable Mining of Automatically Generated Test Cases from Software Requirements Specification (SRS)

    CERN Document Server

    Raamesh, Lilly

    2010-01-01

    Writing requirements is a two-way process. In this paper we use to classify Functional Requirements (FR) and Non Functional Requirements (NFR) statements from Software Requirements Specification (SRS) documents. This is systematically transformed into state charts considering all relevant information. The current paper outlines how test cases can be automatically generated from these state charts. The application of the states yields the different test cases as solutions to a planning problem. The test cases can be used for automated or manual software testing on system level. And also the paper presents a method for reduction of test suite by using mining methods thereby facilitating the mining and knowledge extraction from test cases.

  7. The Integrated Equipment Test Facility At Oak Ridge As A Nonproliferation Test Loop

    International Nuclear Information System (INIS)

    The apparent renaissance in nuclear power has resulted in a new focus on nonproliferation measures. There is a lot of activity in development of new measurement technologies and methodologies for nonproliferation assessment. A need that is evolving in the United States is for facilities and test loops for demonstration of new technologies. In the late 1970s, the Fuel Recycle Division at Oak Ridge National Laboratory (ORNL) was engaged in advanced reprocessing technology development. As part of the program, the Integrated Equipment Test (IET) facility was constructed as a test bed for advanced technology. The IET was a full-scale demonstration facility, operable on depleted uranium, with a throughput capacity for 0.5 Mt/d. At the front end, the facility had a feed surge vessel, input accountability tank, and feed vessel for the single cycle of solvent extraction. The basic solvent extraction system was configured to use centrifugal contactors for extraction and scrub and a full-size pulsed column for strip. A surge tank received the solvent extraction product solution and fed a continuous operating thermo-syphon-type product evaporator. Product receiving and accountability vessels were available. Feed material could be prepared using a continuous rotary dissolve or by recycling the product with adjustment as new feed. Continuous operations 24/7 could be realized with full chemical recovery and solvent recycle systems in operation. The facility was fully instrumented for process control and operation, and a full solution monitoring application had been implemented for safeguards demonstrations, including actual diversion tests for sensitivity evaluation. A significant effort for online instrument development was a part of the program at the time. The fuel recycle program at Oak Ridge ended in the early 1990s, and the IET facility was mothballed. However, the equipment and systems remain and could be returned to service to support nonproliferation demonstrations. This

  9. Experimental equipment design and testing of the DEOX process

    International Nuclear Information System (INIS)

    Several technologies exist or are under development for treating spent oxide fuels. Foremost among these are aqueous and pyrochemical reprocessing which both involve head-end fuel dissolution step. This dissolution step may potentially be shortened if it is combined with a fuel decladding and size reduction process. Declad and Oxidize (DEOX), an advanced head-end processing concept, is being assessed at Argonne National Laboratory (ANL) to meet these decladding and size reduction needs via the oxidation of UO2 to U3O8. DEOX is intended to remove the spent fuel from its cladding, while avoiding oxidation of the cladding that would contaminate the product. An additional goal is to obtain a product particle size distribution between 45 μm to 4 mm. DEOX begins with uranium oxide (UO2) spent fuel pins. Remote tools are used to cut the fuel into segments. Additional equipment is then employed to heat the segments and exposes them to oxygen. The UO2 oxidizes to U3O8 per the reaction 3UO2 + O2 = U3O8, it undergoes a corresponding volume increase, which pulverizes the fuel. This volume increase may cause the pin cladding to split, allowing fuel to escape. Mechanical sieving can further separate the pulverized fuel and cladding. The fuel may then be treated by either aqueous or pyrochemical methods, and the cladding can be disposed of through existing techniques. The DEOX experiments are planned to be run in the argon portion of the Hot Fuel Examination Facility at ANL. During the design phase, engineers identified 6 major components: 1) the fuel cutter - to chop the fuel pins to the desired length; 2) the fuel container - to hold the chopped fuel pieces during processing; 3) the furnace - to heat the fuel samples; 4) the containment vessel - to seal out argon from the hot cell but expose the fuel samples to a pure oxygen environment; 5) the off gas filter - to capture off-gases; and 6) the gas panel - to regulate air-flow and pressure. All the components of the DEOX

    Aquatic ecosystems are major sources of greenhouse gases (GHG). Robust measurements of natural GHG emissions are vital for evaluating regional to global carbon budgets and for assessing climate feedbacks on natural emissions to improve climate models. Diffusive and ebullitive (bubble) transport are two major pathways of gas release from surface waters. To capture the high temporal variability of these fluxes in a well-defined footprint, we designed and built an inexpensive automatic device that includes an easily mobile diffusive flux chamber and a bubble counter, all in one. Besides a function of automatically collecting gas samples for subsequent various analyses in the laboratory, this device utilizes low cost CO2 sensor (SenseAir, Sweden) and CH4 sensor (Figaro, Japan) to measure GHG fluxes. To measure the spatial variability of emissions, each of the devices is equipped with an XBee module to enable a local radio communication DigiMesh network for time synchronization and data readout at a server-controller station on the lakeshore. Software of this server-controller is operated on a low cost Raspberry Pi computer which has a 3G connection for remote monitoring - controlling functions from anywhere in the world. From field studies in Abisko, Sweden in summer 2014 and 2015, the system has resulted in measurements of GHG fluxes comparable to manual methods. In addition, the deployments have shown the advantage of a low cost automatic network system to study GHG fluxes on lakes in remote locations.

    This paper describes the experimental tests performed in order to prove the reliability parameters for FFLS and HTSRM equipments manufactured in INR Pitesti, for NPP CANDU Cernavoda.The tests were provided by Technical Specifications and test procedures. The laboratory tests were performed in such running and environmental conditions that correspond to the real operating ones for the equipments under testing. A special attention was paid to the accelerated tests (intensive tests), where stress level applied is above the level established by reference condition (stated by design); the acceleration of the operating conditions in the sense of a time compressing may be considered, in the case of a product where it was stated that the reliability parameters depend mainly on the number of the operating cycles. A comparison, referring to the reliability parameters, between Canadian equipments and INR manufactured equipments is also given. On the other hand, there are presented reliability improvement measures taken in order to check that the equipments would operate within design specification. The results of tests and the conclusions are also shown. I also mention that this paper is a partial layout of the results of the Scientific Research Contract concluded with IAEA Vienna and completed in the end of 1991, where the author have been Chief Scientific lnvestigator.

The TLD system consists of: two automatic TLD reader, model DOSACUS, a TLD irradiator and personal dosimeters card including slide and holders. The dosimeters were composed by this personal dosimeters card and LiF:Mg,Cu,P (model GR-200) detectors. These readers provide to detectors a constant temperature readout cycle using hot nitrogen gas. In order to evaluate the performance characteristics of the system, different performance tests recommended by the IEC 1066 standard were carried out. Important dosimetric characteristics evaluated were batch homogeneity, reproducibility, detection threshold, energy dependence, residual signal and fading. The results of the tests showed good performance characteristics of the system. (Author)

    cases and validation points from a set of annotated use cases. This technique helps to reduce the effort required in GUI modeling and test coverage analysis during the software testing process. The test case generation process described in this paper is initially guided by use cases describing the GUI behavior, recorded as a set of interactions with the GUI elements (e.g., widgets being clicked, data input, etc.. These use cases (modeled as a set of initial test cases are annotated by the tester to indicate interesting variations in widget values (ranges, valid or invalid values and validation rules with expected results. Once the use cases are annotated, this approach uses the new defined values and validation rules to automatically generate new test cases and validation points, easily expanding the test coverage. Also, the process allows narrowing the GUI model testing to precisely identify the set of GUI elements, interactions, and values the tester is interested in.

    International Nuclear Information System (INIS)

    Since 1984 the Regional Medical Physics Department has participated in a regional acceptance testing programme for all X-ray equipment from mobile units to computed tomography scanners. The organizational and radiation physics aspects of the programme are described. Three levels of tests are performed by physicists: the first on installation, the second after 3 months, and the final visit just prior to the end of the manufacturer's warranty. The second test is only performed if any aspect of performance requires rechecking as a result of the first visit. Acceptance test protocols are based on those published by the Institute of Physical Sciences in Medicine. Details of the limiting values for the acceptance test measurements are given. The results of the programme are discussed. In some instances the testing has resulted in modifications to the design and construction of X-ray equipment. Acceptance testing is important in determining a baseline standard of performance against which routine quality assurance may be assessed. (author)

    Energy Technology Data Exchange (ETDEWEB)

    Boyce, K.; Chapin, J. T.

    2010-11-01

    The National Renewable Energy Laboratory's (NREL) Nonpetroleum-Based Fuel Task addresses the hurdles to commercialization of biomass-derived fuels and fuel blends. One such hurdle is the unknown compatibility of new fuels with current infrastructure, such as the equipment used at service stations to dispense fuel into automobiles. The U.S. Department of Energy's (DOE) Vehicle Technology Program and the Biomass Program have engaged in a joint project to evaluate the potential for blending ethanol into gasoline at levels higher than nominal 10 volume percent. This project was established to help DOE and NREL better understand any potentially adverse impacts caused by a lack of knowledge about the compatibility of the dispensing equipment with ethanol blends higher than what the equipment was designed to dispense. This report provides data about the impact of introducing a gasoline with a higher volumetric ethanol content into service station dispensing equipment from a safety and a performance perspective.

    2015-03-01

    The combination of highly controlled experimental testing and the voluntary participation of unrestrained animals has many advantages over traditional, laboratory-based learning environments in terms of animal welfare, learning speed, and resource economy. Such automatic learning environments have recently been developed for primates (Fagot & Bonté, 2010; Fagot & Paleressompoulle, 2009;) but, so far, has not been achieved with highly mobile creatures such as birds. Here, we present a novel testing environment for pigeons. Living together in small groups in outside aviaries, they can freely choose to participate in learning experiments by entering and leaving the automatic learning box at any time. At the single-access entry, they are individualized using radio frequency identification technology and then trained or tested in a stress-free and self-terminating manner. The voluntary nature of their participation according to their individual biorhythm guarantees high motivation levels and good learning and test performance. Around-the-clock access allows for massed-trials training, which in baboons has been proven to have facilitative effects on discrimination learning. The performance of 2 pigeons confirmed the advantages of the automatic learning device for birds box. The latter is the result of a development process of several years that required us to deal with and overcome a number of technical challenges: (1) mechanically controlled access to the box, (2) identification of the birds, (3) the release of a bird and, at the same time, prevention of others from entering the box, and (4) reliable functioning of the device despite long operation times and exposure to high dust loads and low temperatures.

  3. Sipping equipment for leak testing of fuel assemblies in VVER-440 reactors

    International Nuclear Information System (INIS)

    Sipping equipment for the Soviet-type VVER-440 pressurized water reactors was developed on the basis of the proven in-core sipping technique used for boiling water reactor fuel assemblies. The main components of the system are the sipping hood with seven test positions, the control panel for system operation and sample collection, and the manifold connection line. During testing the upper ends of the hexagonal fuel assemblies are lifted into the air-filled sipping hood to interrupt the coolant flow by means of pneumatically actuated grippers. The first equipment of this kind has been in use in the nuclear plant Jaslovske-Bohunice, Czechoslovakia, since 1986. (orig.)

  5. Design validation of the 4S high temperature electromagnetic pump by one pole segment test equipment

    International Nuclear Information System (INIS)

    The small fast reactor 4S (Super Safe Small and Simple) adopts high temperature sodium immersed electromagnetic pump (EMP) as a primary pump. The reason is that EMP is able to satisfy the low maintenance, safety and reliability requirements for 4S, because it has simple structure and no moving parts. Technical challenges of 4S EMP are the following three items.The first is to confirm manufacturability of 4S EMP. 4S EMP has the world greatest dimension coil and stator and flattened shape with the aspect ratio (outer diameter / stator length) of 1.8. The 4S prototype EMP as same as practical dimension and the one pole segment test equipment were manufactured in JFY 2008. The second is to construct the back up power supply system for flow coast down. It will be confirmed by combination test of 4S prototype EMP and the system in JFY 2010. The third is to confirm low maintenance for 30 years. A part of long-term soundness test of coil is tested by heat cycle test with one pole test equipment discussed in the next section. Furthermore, as the future development subject, the seismic assessment and the long-term soundness test of the EMP body by the sodium fluid test has been planned. The one pole segment test equipment is used for evaluation of following items. The first is the integrity of the electrical insulation of large diameter coil. Insulation breakdown will be estimated due to thermal expansion in coil during operation, thus, the heat cycle is loaded to the equipment simulating start-and-stop of 4S. Insulation resistance, leak current and tan δ will also be measured in several steps of coil temperature. The second is validation whether stator support system of the EMP would work as designed. In practical 4S EMP, all of Joule heat by energization of the coil during operation is transferred into sodium through core and duct. To keep the heat transfer system, in the outer stator, the core is pressed upon the duct by spring plates. Therefore, it is important to

  10. Design and tests of the screw denitration equipment using microwave heating

    International Nuclear Information System (INIS)

    A continuous denitration equipment which uses a microwave heating technique is designed and tested. A screw is incorporated for feeding material. Major features of this technique include easiness of pellet molding due to high activity of powder, decreased amount of waste and waste liquid released and easy operation and maintenance due to simplified processes. The equipment consists of a solution supply pipe, denitrated material discharge pipe, microwave guide, offgas exhaust pipe and screw feeder, all of which are connected to a denitration oven. Tests are performed for determining microwave absorption efficiency, processing capacity and performance. Cerium nitrate solution is employed as sample to simulate uranyl nitrate solution. Parameters used include the solution retention volume, inclination of the screw shaft, clearance between the screw and the trough, and solution concentration. The maximum microwave absorption efficiency is found to be 50 percent. Measurements also show that the equipment requires 3.5 - 4.5 hours to reach a stationary state. The size of dried material depends on the revolution speed of the screw. In the performance confirmation test, the equipment is operated continuously for 52 hours while measuring the fluctuation in the torque of the screw motor shaft and the properties of dried material discharged. Results show that the equipment can operate continuously while meeting the design conditions. (Nogami, K.)

    Science.gov (United States)

    Morales-Cid, Gabriel; Cárdenas, Soledad; Simonet, Bartolomé M; Valcárcel, Miguel

    2009-04-15

    This paper describes a new and innovative way to integrate microextraction by packed sorbents (MEPS) into commercial CE equipment. The suggested integration allows the automatic sample cleanup and preconcentration requiring only a few microliters of sample and no additional hardware and software. The MEPS was integrated in the outlet region of a commercial CE equipment cartridge in order to provide easy manipulation and exchange. The robustness of the proposed integration was demonstrated by the design and use of a (MEPS)-nonaqueous capillary electrophoresis (NACE)-MS method used to determine fluoroquinolones "FQs" (namely, ofloxacin, marbofloxacin, enrofloxacin, danofloxacin, and difloxacin) in urine. The method allows the analysis of micrograms per liter of FQs to be carried out with only 48 microL of urine sample. The obtained LODs were in the range 6.3-10.6 microg/L. An analysis of spiked urine samples was used to validate the method. Absolute recoveries were in the range of 71-109% while the precision expressed as repetitivity of peak area was lower than 5.9%.

    International Nuclear Information System (INIS)

    HTTR was established at the Oarai Research and Development Center of Japan Atomic Energy Agency, for the purpose of the establishment and upgrading of high-temperature gas-cooled reactor technology infrastructure. Currently, it performs a safety demonstration test in order to demonstrate the safety inherent in high-temperature gas-cooled reactor. After the Great East Japan Earthquake, it conducted confirmation test for the purpose of soundness survey of facilities and equipment, and it confirmed that the soundness of the equipment was maintained. After two years from the confirmation test, it has not been confirmed whether the function of dynamic equipment and the soundness such as the airtightness of pipes and containers are maintained after receiving the influence of damage or deterioration caused by aftershocks generated during two years or aging. To confirm the soundness of these facilities, operation under cold state was conducted, and the obtained plant data was compared with confirmation test data to evaluate the presence of abnormality. In addition, in order to confirm through cold test the damage due to aftershocks and degradation due to aging, the plant data to compare was supposed to be the confirmation test data, and the evaluation on abnormality of the plant data of machine starting time and normal operation data was performed.

  1. TANK 18 AND 19-F TIER 1A EQUIPMENT FILL MOCK UP TEST SUMMARY

    Energy Technology Data Exchange (ETDEWEB)

    Stefanko, D.; Langton, C.

    2011-11-04

    The United States Department of Energy (US DOE) has determined that Tanks 18-F and 19-F have met the F-Tank Farm (FTF) General Closure Plan Requirements and are ready to be permanently closed. The high-level waste (HLW) tanks have been isolated from FTF facilities. To complete operational closure they will be filled with grout for the purpose of: (1) physically stabilizing the tanks, (2) limiting/eliminating vertical pathways to residual waste, (3) discouraging future intrusion, and (4) providing an alkaline, chemical reducing environment within the closure boundary to control speciation and solubility of select radionuclides. Bulk waste removal and heel removal equipment remain in Tanks 18-F and 19-F. This equipment includes the Advance Design Mixer Pump (ADMP), transfer pumps, transfer jets, standard slurry mixer pumps, equipment-support masts, sampling masts, dip tube assemblies and robotic crawlers. The present Tank 18 and 19-F closure strategy is to grout the equipment in place and eliminate vertical pathways by filling voids in the equipment to vertical fast pathways and water infiltration. The mock-up tests described in this report were intended to address placement issues identified for grouting the equipment that will be left in Tank 18-F and Tank 19-F. The Tank 18-F and 19-F closure strategy document states that one of the Performance Assessment (PA) requirements for a closed tank is that equipment remaining in the tank be filled to the extent practical and that vertical flow paths 1 inch and larger be grouted. The specific objectives of the Tier 1A equipment grout mock-up testing include: (1) Identifying the most limiting equipment configurations with respect to internal void space filling; (2) Specifying and constructing initial test geometries and forms that represent scaled boundary conditions; (3) Identifying a target grout rheology for evaluation in the scaled mock-up configurations; (4) Scaling-up production of a grout mix with the target rheology

  2. Automatic ultrasonic testing for hydrogen-induced cracking of pipeline steels

    International Nuclear Information System (INIS)

    The laboratory measuring equipment for ultrasonic testing of plane and curved HTC test samples allows an economical evaluation of a large number of samples under objective test conditions. By application of modern ultrasonics electronics, computer-controlled testing mechanisms and corresponding software, evaluations can be carried out and documented according to different criteria. Sensor-specific non-linearities such as the depth characteristics of the probes used, can be compensated by suitable software modules. By means of ultrasonic evaluations of HIC samples according to the impulse reflection method, further developments in steel plants - treatment of molten metal and casting conditions - could be controlled and optimized. For the execution of orders for acid-gas-resistant pipelines the testing methods could be used successfully for continuous control of the quality standard. (orig./DG)

  7. Design and installation of extra high voltage cryogenic dielectric test facilities for the superconducting electric equipment

    International Nuclear Information System (INIS)

    We installed high voltage cryogenic dielectric test facilities including big FRP cryostat. We designed 3 m long and 2 m wide cryostat system with busing. Low temperature and high voltage bushing were fabricated and tested. CF4 gas shows excellent characteristics in low temperature insulation. High voltage bushing could be modified for low temperature environment. Superconducting electric equipments have a lot of advantages over the conventional devices such as improvements in overall efficiency, size reduction, high current carrying capability, and also environment-friendly products. Owing to these advantages, many research institutes have been tried to develop commercial superconducting devices, which could be applicable to the high voltage and high current electric networks. But up to now, most of the research works to develop commercial products were delayed because it was not easy to acquire reliable high voltage insulation properties and optimum insulation design skills considering extremely low temperature environments. Furthermore, it was difficult to determine optimum high voltage insulation level due to the lack of high voltage cryogenic dielectric test facilities. Thus, in order to establish the cryogenic dielectric technology regarding insulating design, cryogenic dielectric test skills, and to implement more reliable high voltage superconducting devices, high voltage cryogenic dielectric test facilities should be prepared for extra high voltage superconducting electric equipments. Recently, cryogenic dielectric test facilities were installed including 3 m long 2 m wide cryostat system with bushing, and 1.6 MVA lightening impulse generators, 400 kVA AC overvoltage test system in Korea. In this paper, design and installation of high voltage cryogenic dielectric test system including very big size FRP cryostat and high voltage bushing were minutely introduced. And some test results to develop high voltage bushings for liquid nitrogen cryostat in order to

    The rate performance of inertial guidance test equipment (IGTE) affects the performance testing of inertia devices and navigation systems. Periodic rate ripples caused by periodic disturbances have a great effect on the rate performance of rotation test tables. The mechanism caused by the rate ripple in IGTE is analyzed. Based on the nonlinear self-adaptive control system approach, a control system scheme is proposed to eliminate the period disturbances for its uncertainty. Experimental results show that the periodic rate ripple can efficiently be controlled.

    Collimators with embedded Beam Position Monitor (BPM) buttons will be installed in the LHC during the upcoming long shutdown period. During the subsequent operation, the BPMs will allow the collimator jaws to be kept centered around the beam trajectory. In this manner, the best possible beam cleaning efficiency and machine protection can be provided at unprecedented higher beam energies and intensities. A collimator alignment algorithm is proposed to center the jaws automatically around the beam. The algorithm is based on successive approximation, as the BPM measurements are affected by non-linearities, which vary with the distance between opposite buttons, as well as the difference between the beam and the jaw centers. The successful test results, as well as some considerations for eventual operation in the LHC are also presented.

  15. Automatic monitoring of radial injection tracer tests using a novel multi-electrode resistivity system

    International Nuclear Information System (INIS)

    A radial injection tracer test has been carried out in an unconfined fluvial sand and gravel aquifer underlain by low permeability clay. Sodium chloride has been used as an electrolyte tracer and breakthrough has been monitored using a newly developed automatic resistivity system (RESCAN) incorporating six fully penetrating resistivity probes each having 80 electrodes spaced at 5 cm intervals along their length. Each electrode is individually addressable under computer control to either carry current or measure potential. Any four electrodes can be selected in the traditional Wenner configuration to measure formation resistivity. Rapid measurement of changes in resistivity allows a very detailed picture of tracer migration to be obtained. The resistivity probes were placed at 1 and 2 m radii from the central fully-screened tracer injection well along three limbs at 120 degrees. Resistivity measurements were compared with adjacent multi-level samplers. An 8 x 8 m grid of 140 surface electrodes centred on the central well was also installed. The resistivity profiles measured prior to tracer injection were used to infer lithology, particularly layering. Detailed breakthrough curves were obtained at 77 positions along each of the six probes and compared with adjacent multi-level sampler breakthrough curves. The results showed that the aquifer was extremely heterogeneous even on this small scale. Because the system operates automatically without the need to extract and analyse large numbers of water samples, it opens up the possibility of carrying out lots of small scale injection tests within a larger domain likely to be invaded by a tracer or pollution plume. Such detailed information for determining aquifer properties can provide the data set necessary for characterisation of the aquifer to predict dispersion parameters appropriate to the large scale.

  16. Novel automatic phase lock determination for superconducting cavity tests at vertical test stand at RRCAT

    International Nuclear Information System (INIS)

    RRCAT has developed a Vertical Test Stand (VTS) which is used to test the Nb superconducting cavities under cryogenic conditions. In the VTS, RF cavity is characterized for its quality factor variation vs the accelerating gradient. The RF system is an essential part of the VTS which is required to provide stable RF power to the cavity in terms of amplitude, frequency and phase. RF system of VTS consists of several modules including the LLRF system. The LLRF system consists of the 'Frequency Control Module' which controls the input frequency to the SCRF cavity. Due to high quality factor, bandwidth of the cavity is less than 1 Hz. Even slight mechanical vibrations (microphonics) causes change in cavity resonance frequency resulting in total reflection of incident power. A PLL based frequency tracking module has been used to track the resonant frequency of RF cavity. This module changes RF source frequency according to change in Cavity resonance frequency. A novel method using a LabView based computer program has been developed which changes the phase of input RF signal using IQ modulator and monitors the transmitted power, incident and reflected power. The program plots the graph between phase and ratio of transmitted power to incident/reflected power and gives optimum locking phase for operation which has resulted in significant saving in the overall process time for the tests of the cavities in VTS.

    The half-core model with the same configuration as the HANARO reactor, however which the sectional area of the core was cut down half, was developed to test the performance and improve the design of the capsules outside the reactor. The three different materials of aluminium, Zircalloy-4 and SUS304 are used in the HANARO reactor, however, only SUS304 material is used in the test facility because there's no need to consider the effect of neutrons and radiation on it. The 14 sight glasses are installed to view the inside flow and the vibration, and 17 flow receptacles are furnished so that the corresponding flow tubes will be fit in when the half core system will be equipped in the future. The leak tightness was confirmed through the hydraulic pressure test which has the different test pressures of 160kpa and 470kpa at upper and lower part. This test facility can be contributed to the design verification and the performance improvement through the capsule loading test, the hydraulic performance test, the vibration and the endurance test etc.. In addition, this facility can be used on the multi-purpose test such as the drop time test of SO/CA rod after the scheduled drop times, the vibration test of the HANARO fuel and the test of various tools for HANARO operation.

The average error±2SD, %CV, and r value was spine : 0.006±0.024 g/cm2, %CV=0.86, r=0.995, Femur: 0±0.014 g/cm2, %CV=0.54, r=0.998 in Group 4. Both LUNAR ASP CV% and HOLOGIC Spine Phantom are included in the normal range of error of ±2% defined in ISCD. BMD measurement keeps a relatively constant value, so showing excellent repeatability. The Phantom has homogeneous characteristics, but it has limitations to reflect the clinical part including variations in patient's body weight or body fat. As a result, it is believed that quality control using Phantom will be useful to check mis-calibration of the equipment used. A value measured a patient two times with one equipment, and that of double-crossed two equipment are all included within 2SD Value in the Bland - Altman Graph compared results of Group 3 with Group 4. The r value of 0.99 or higher in Linear regression analysis(Regression Analysis) indicated high precision and correlation. Therefore, it revealed that two compatible equipment did not affect in tracking the patients. Regular testing equipment and capabilities of a tester, then appropriate calibration will have to be achieved in order to calculate confidential BMD.

    Toshiba has developed the Super-Safe, Small and Simple sodium-cooled reactor, named as 4S. 4S has the features that the passive safety design, no on-site refuelling for 30 years, the low maintenance. 4S adopts a high temperature sodium immersed electromagnetic pump (EM pump) as the primary pump. The coil diameter of 4S EM pump is one and a half times as larger than that of 160 m3/min EM pump which Toshiba has already developed. To confirm the manufacturability of the large diameter coil with the high temperature insulation and the large size stator, the one pole segment test equipment, which has one-sixth height and same size radius of 4S EM pump, was manufactured. In this paper, the test results of the one pole segment test equipment are reported. It was confirmed the structural integrity of EM pump caused by the electromagnetic oscillation by the energization of a coil. By the heat cycle test, it was able to confirm the structural integrity during the operation of 4S EM pump and the insulation performance in the high-temperature environment. These test results would be reflected the design and the manufacture of 4S EM pump. (author)

    Ultrasonic flow detection when compared with the radiation transmission detection, has advantages such as: it can be used even in thick plate, detection performance of surface defects like cracks or bad unification and so forth is good, possesses easier safety management and so forth. On the other hand, it is a manual testing and lacks memory, and has problem that the test results depend on the ability of technician and automation is preferred in many field. However, the manual scanning method of probe carried out by experienced technicians can not be replaced by automation because the signals obtained depend greatly on the surface condition of specimen, scanning speed of probe and welding pressure. At present, the memory capacity and computation ability of computer have been significantly developed and image processing and photo taking of the obtained results are carried out easily. In this report, practical image of ultrasonic flow detection of weld portion is discussed and some practical examples of automatic test devices for welding structures are introduced. 16 refs., 6 figs., 1 tab.

    2009-12-01

    Full Text Available This paper deals with an evaluation platform for cryptographic True Random Number Generators (TRNGs based on the hardware implementation of statistical tests for FPGAs. It was developed in order to provide an automatic tool that helps to speed up the TRNG design process and can provide new insights on the TRNG behavior as it will be shown on a particular example in the paper. It enables to test sufficient statistical properties of various TRNG designs under various working conditions on the fly. Moreover, the tests are suitable to be embedded into cryptographic hardware products in order to recognize TRNG output of weak quality and thus increase its robustness and reliability. Tests are fully compatible with the FIPS 140 standard and are implemented by the VHDL language as an IP-Core for vendor independent FPGAs. A recent Flash based Actel Fusion FPGA was chosen for preliminary experiments. The Actel version of the tests possesses an interface to the Actel’s CoreMP7 softcore processor that is fully compatible with the industry standard ARM7TDMI. Moreover, identical tests suite was implemented to the Xilinx Virtex 2 and 5 in order to compare the performance of the proposed solution with the performance of already published one based on the same FPGAs. It was achieved 25% and 65% greater clock frequency respectively while consuming almost equal resources of the Xilinx FPGAs. On the top of it, the proposed FIPS 140 architecture is capable of processing one random bit per one clock cycle which results in 311.5 Mbps throughput for Virtex 5 FPGA.

  8. Presentation of accessibility equipment for primary pipings, IHX, pumps and appertaining manipulator tests

    International Nuclear Information System (INIS)

    Accessibility and inservice procedure of SNR-300 components are described. Due to the high radiation level in the primary system it was necessary to develop special equipment to permit access to the testing components. The pertinent examination methods for surveying welding seams are acoustic (ultrasonic) and optical procedures (TV cameras, surface crack tests). This can be done by remote-controlled manipulators and special devices, which can transport the inspection system by rails to the testing position. Presently, relatively limited experience exists for such remote-controlled handling in nuclear power plants. Thus model experiments were carried out on a model pipe section at INTERATOM. The performed test shows that the concept planned to perform inservice by using remote-controlled manipulators can be realized successfully. (author)

  9. Torque test for bolts/screws in maintaining equipment seismic qualification

    International Nuclear Information System (INIS)

    In an operating nuclear power plant, the original seismic qualification of Class 1E equipment is usually performed by testing the entire enclosure/cabinet with all devices. This paper presents the laboratory torque test results corresponding to snug tight, 1/16 and 1/8 turn past snug tight position for small screws with different materials, mounted using different connection details on thin plates with various thicknesses. The test results compare reasonably well with the theoretical values. Based on the test results, the number of turns past snug tight is recommended for small screws when turn of the nut method is used to control bolt preload and maintain original equipment seismic qualification. It should be noted that for light weight electrical and mechanical assemblies where small bolts/screws require only moderate torque, the snug tight method of applying torque is in general sufficient for all practical purposes. However, for nuclear plants located in high seismic zones, torque beyond snug tight may be required for mounting devices on thin flexible subpanels of cabinets which require seismic qualification

    International Nuclear Information System (INIS)

    This report describes the equipment and techniques used to investigate the variation of hydrogeological parameters within a fractured crystalline rock mass. The testing program was performed during stage 3 of the site characterization and validation programme at the Stripa mine in Sweden. This programme used a multidisciplinary approach, combining geophysical, geological and hydrogeological methods, to determine how groundwater moved through the rock mass. The hydrogeological work package involved three components. Firstly, novel single borehole techniques (focused packer testing) were used to determine the distribution of hydraulic conductivity and head along individual boreholes. Secondly, water was abstracted from boreholes which were drilled to simulate a tunnel (simulated drift experiment). Locations and magnitudes of flows were measured together with pressure responses at various points in the SCV rock mass. Thirdly, small scale crosshole tests, involving detailed interference testing, were used to determine the variability of hydrogeological parameters within previously identified, significant flow zones.

  12. Some lessons learned from developing, testing and using border monitoring equipment for the last decade

    International Nuclear Information System (INIS)

    An experience gained by several countries in creating systems of border (customs) radiation control for the last decade since the beginning of the well-known ITRAP program provides a possibility to learn definite lessons and to assess the promising progress of international efforts aimed to combat illicit trafficking in nuclear and other radioactive materials across the state borders and territories. The main result and lessons learned are that the specialized equipment is required to solve tasks of border (customs) radiation control; at the same time, developers and manufacturers of equipment, on one hand, and developers of standards and recommendations, on the other hand, are much concerned with the only technical part of radiation control; the main efforts are made to search new technical solutions, detectors, electronics, etc.; new and very expensive equipment has appeared (spectroscopic portal monitors, radiation scanners, etc). However recent research indicated that the effectiveness of using such equipment significantly depends on the operation procedures, e.g. according to developed concept of 'two-tier approach' the plastic based portal monitors are used for the primary control in the 'pass-through' mode at the first tier, and the spectroscopic portal monitor is used at the second tier in the 'stand-in' mode. The recent tests of this approach showed promising results. Previous research made by the authors for gamma-neutron personal radiation detectors and backpacks also showed that, without properly elaborated operation procedures, the use of these instruments in the real field conditions is very questionable and, sometimes, even not possible. Operation procedures means here: (i) definition of scenarios of radiation control; (ii) analysis of possible places of installation or application of equipment; (iii) definition of the maximum distance between a detector and the probable worst case of appearance of a radioactive source; (iv) definition of the minimum

    The Vitrification Facility (VF) at the West Valley Demonstration Project was designed to convert stored radioactive waste into a stable glass for disposal in a federal repository. The Functional and Checkout Testing of Systems (FACTS) program was conducted from 1984 to 1989. During this time new equipment and processes were developed, installed, and implemented. Thirty-seven FACTS tests were conducted, and approximately 150,000 kg of glass were made by using nonradioactive materials to simulate the radioactive waste. By contrast, the planned radioactive operation is expected to produce approximately 500,000 kg of glass. The FACTS program demonstrated the effectiveness of equipment and procedures in the vitrification system, and the ability of the VF to produce quality glass on schedule. FACTS testing also provided data to validate the WVNS waste glass qualification method and verify that the product glass would meet federal repository acceptance requirements. The system was built and performed to standards which would have enabled it to be used in radioactive service. As a result, much of the VF tested, such as the civil construction, feed mixing and holding vessels, and the off-gas scrubber, will be converted for radioactive operation. The melter was still in good condition after being at temperature for fifty-eight of the sixty months of FACTS. However, the melter exceeded its recommended design life and will be replaced with a similar melter. Components that were not designed for remote operation and maintenance will be replaced with remote-use items. The FACTS testing was accomplished with no significant worker injury or environmental releases. During the last FACTS run, the VF processes approximated the remote-handling system that will be used in radioactive operations. Following this run the VF was disassembled for conversion to a radioactive process. Functional and checkout testing of new components will be performed prior to radioactive operation

    The Electricity at Work Regulations 1989 requires any electrical system to be constructed, maintained and used in such a manner as to prevent danger. This means that inspection and testing of systems, including portable appliances, is needed in order to determine if maintenance is required. This book explains in clear language what needs to be done and includes expert advice on legislation as well as actual testing. The book contains an appendix providing the electrical fundamentals needed by non-specialists and also has sample questions (with answers) for the C&G 2377 exam. It is also an ideal revision guide for the non-specialist, such as maintenance staff and caretakers who carry out these tasks part-time, alongside their many other duties.

  15. Characterization of liquid entrainment in the AP1000 automatic depressurization system from APEX tests

    International Nuclear Information System (INIS)

    Full text of publication follows: The AP1000 is a 1000 MWe advanced nuclear power plant that uses passive safety features to enhance plant safety and to provide significant and measurable improvements in plant simplification, reliability, investment protection and plant costs. The AP1000 relies heavily on the 600 MWe AP600 which received design certification in 1999. A critical part of the AP600 design certification process involved the testing of the passive safety systems. A one-fourth height, one-fourth pressure test facility, APEX-600, was constructed at the Oregon State University to study design basis events, and to provide a body of data to be used to validate the computer models used to analyze the AP600. This facility was extensively modified to reflect the design changes for AP1000 including higher power in the electrically heated rods representing the reactor core, and changes in the size of the pressurizer, core makeup tanks and automatic depressurization system. The APEX-1000 test facility was used to perform design basis accident simulations and separate effects tests to support the AP1000 design certification process. In the event of a LOCA, the AP1000 passive core cooling system provides sources of core makeup water along with an automatic depressurization system (ADS) consisting of several stages of valves which reduce the reactor coolant system pressure in a controlled manner. The final stage of this system, ADS-4, consists of four large valves that open off the hot legs, reducing the pressure to allow gravity injection from the in-containment refueling water storage tank (IRWST) and eventually the containment sump. The 67% increase in power from AP600 to AP1000 results in proportionally larger steam velocities exiting the core. Higher steam velocities could increases the potential for significant liquid entrainment out the ADS-4 lines, affecting the liquid inventory in the reactor. Tests were performed in APEX-1000 to characterize the two

  17. Comparison of different phantom designs for CT scanner automatic tube current modulation system tests

    International Nuclear Information System (INIS)

    Modern CT scanners modulate tube current during scans according to patient size, shape and attenuation. However, the ATCM (automatic tube current modulation) systems for different CT manufacturers work on different principles. Although the systems are used for the majority of patients and examinations, there is no standard phantom for routine quality control of CT scanner ATCM operation. The ideal phantom for testing these systems should be capable of evaluating how tube current and image quality as well as dose vary according to changes in patient size and shape. For this study, a conical phantom designed by ImPACT has been compared with two phantoms made from elliptical sections with varying dimensions. The concept of the designs is to reflect the ATCM performance for the varying shapes and dimensions along the length of the human body. The first phantom comprises five elliptical sections with a wide range of different dimensions and the second has three sections that are more similar in size. The phantoms have been used to test ATCM systems for Philips, Siemens, GE and Toshiba scanners. Although the results of the tube current modulation patterns were similar for all CT scanners, the abrupt changes in attenuation for the first sectional phantom provoked an abnormal ATCM response for the GE and Toshiba scanners. The second sectional phantom was developed from the results of the first, and was more effective for ATCM system testing and could be used for dose and image quality assessment in standard positions. However, the ImPACT conical phantom provided the best overall assessment of performance in terms of tube current modulations and noise pattern. (paper)

  18. NRC Information No. 91-61: Preliminary results of validation testing of motor-operated valve diagnostic equipment

    International Nuclear Information System (INIS)

    In 1990, the MUG (Mov User's Group) initiated a program to conduct tests of MOV diagnostic equipment to validate the accuracy of the equipment asserted by the diagnostic equipment vendors. The MUG requested the Idaho National Engineering Laboratory (INEL) to provide a test stand for the program and to collect test data. The NRC Office of Nuclear Regulatory Research (RES) provided funds for INEL to participate, with the stipulation that the results of the testing would be made available to the NRC and the public. The INEL test stand included a Limitorque motor operator which drives a valve stem into a water reservoir with a compressed air overcharge. INEL obtained accurate measurements of actuator torque and thrust using a torque arm and a stem-mounted load cell, respectively. Each diagnostic equipment vendor installed and operated its own equipment to obtain measurements of torque, thrust, and various other parameters. Several diagnostic system vendors did not meet all of their stated claims of accuracy. Differences in the time response of the INEL test stand equipment and the diagnostic systems being tested may have contributed to deviations in the observed thrust measurements. Further, some of the diagnostic equipment exhibited problems and anomalies, such as failed sensors or difficulties in calibration, during the testing program. Of particular concern to the NRC is that these time inaccuracies, problems, and anomalies may not have been detected during normal use of the diagnostic equipment at a nuclear facility. The MUG is comparing the data collected by INEL with the data collected by each of the diagnostic equipment vendors

    2015-01-01

    The National Aeronautics and Space Administration (NASA) Armstrong Flight Research Center Small Unmanned Aerial Vehicle (SUAV) Automatic Ground Collision Avoidance System (Auto GCAS) project demonstrated several important collision avoidance technologies. First, the SUAV Auto GCAS design included capabilities to take advantage of terrain avoidance maneuvers flying turns to either side as well as straight over terrain. Second, the design also included innovative digital elevation model (DEM) scanning methods. The combination of multi-trajectory options and new scanning methods demonstrated the ability to reduce the nuisance potential of the SUAV while maintaining robust terrain avoidance. Third, the Auto GCAS algorithms were hosted on the processor inside a smartphone, providing a lightweight hardware configuration for use in either the ground control station or on board the test aircraft. Finally, compression of DEM data for the entire Earth and successful hosting of that data on the smartphone was demonstrated. The SUAV Auto GCAS project demonstrated that together these methods and technologies have the potential to dramatically reduce the number of controlled flight into terrain mishaps across a wide range of aviation platforms with similar capabilities including UAVs, general aviation aircraft, helicopters, and model aircraft.

  2. Development of the automatic test pattern generation for NPP digital electronic circuits using the degree of freedom concept

    International Nuclear Information System (INIS)

    In this paper, an improved algorithm for automatic test pattern generation (ATG) for nuclear power plant digital electronic circuits--the combinational type of logic circuits is presented. For accelerating and improving the ATG process for combinational circuits the presented ATG algorithm has the new concept--the degree of freedom (DF). The DF, directly computed from the system descriptions such as types of gates and their interconnections, is the criterion to decide which among several alternate lines' logic values required along each path promises to be the most effective in order to accelerate and improve the ATG process. Based on the DF the proposed ATG algorithm is implemented in the automatic fault diagnosis system (AFDS) which incorporates the advanced fault diagnosis method of artificial intelligence technique, it is shown that the AFDS using the ATG algorithm makes Universal Card (UV Card) testing much faster than the present testing practice or by using exhaustive testing sets

    International Nuclear Information System (INIS)

    This session starts by providing an overview of typical DCS (Distributed Control Systems) and SCADA (Supervisory Control and Data Acquisition) architectures, and exposes cyber security vulnerabilities that vendors never admit, but are found through a comprehensive cyber testing process. A complete assessment process involves testing all of the layers and components of a SCADA or DCS environment, from the perimeter firewall all the way down to the end devices controlling the process, including what to look for when conducting a vulnerability assessment of real-time control systems. The following systems are discussed: 1. Perimeter (isolation from corporate IT or other non-critical networks) 2. Remote Access (third Party access into SCADA or DCS networks) 3. Network Architecture (switch, router, firewalls, access controls, network design) 4. Network Traffic Analysis (what is running on the network) 5. Host Operating Systems Hardening 6. Applications (how they communicate with other applications and end devices) 7. End Device Testing (PLCs, RTUs, DCS Controllers, Smart Transmitters) a. System Discovery b. Functional Discovery c. Attack Methodology i. DoS Tests (at what point does the device fail) ii. Malformed Packet Tests (packets that can cause equipment failure) iii. Session Hijacking (do anything that the operator can do) iv. Packet Injection (code and inject your own SCADA commands) v. Protocol Exploitation (Protocol Reverse Engineering / Fuzzing) This paper will provide information compiled from over five years of conducting cyber security testing on control systems hardware, software, and systems.

    SCTE intends to provide a simple, yet powerful, framework for building data acquisition and equipment control systems for experimental Physics, and correlated areas. Via its SCTE::Instrument module, RS-232, USB, and LAN buses are supported, and the intricacies of hardware communication are encapsulated underneath an object oriented abstraction layer. Written in Perl, and using the SCPI protocol, enabled instruments can be easily programmed to perform a wide variety of tasks. While this work presents general aspects of the development of data acquisition systems using the SCTE framework, it is illustrated by particular applications designed for the calibration of several in-house developed devices for power measurement in the tokamak TCABR Alfvén Waves Excitement System.

    This work encompassed the development for a frequency-domain impedance and dielectric spectrometer using ubiquitous test and measurement equipment, i.e., signal generators and digital oscilloscopes. Various methods of amplification, noise rejection, and computations were employed to achieve the desired goals. The frequency range of 100 mHz-1 MHz was tested using air capacitors of 3.7 and 14.5 pF and an applied voltage range of 10-300 mV. The multichannel instrument produced a stable and reproducible dual-phase (real and imaginary or magnitude and phase) current sensitivity of 250 fA with an average phase stability of less than 0.5 degrees (tan delta<10(-2)) and a single-phase (magnitude only) current sensitivity of 60 fA.

  9. Automatic test pattern generation for stuck-at and delay faults in combinational circuits

    International Nuclear Information System (INIS)

    The present studies are developed to propose the automatic test pattern generation (ATG) algorithms for combinational circuits. These ATG algorithms are realized in two ATG programs: One is the ATG program for stuck-at fault and the other one for delay faults. In order to accelerate the ATG process, these two ATG programs have a common feature (the search method based on the concept of the degree of freedom), whereas only ATG program for the delay fault utilizes the 19-valued logic, a type of composite valued logic. This difference between two ATG programs results from the difference of the target fault. Accelerating the ATG process is indispensable for improving the ATG algorithms. This acceleration is mainly achieved by reducing the number of the unnecessary backtrackings, making the earlier detection of the conflicts, and shortening the computation time between the implication. Because of this purpose, the developed ATG programs include the new search method based on the concept of the degree of freedom (DF). The DF concept, computed directly and easily from the system descriptions such as types of gates and their interconnections, is the criterion to decide which, among several alternate lines' logic values required along each path, promises to be the most effective in order to accelerate and improve the ATG process. This DF concept is utilized to develop and improve both of ATG programs for stuck-at and delay faults in combinational circuits. In addition to improving the ATG process, reducing number of test pattern is indispensable for testing the delay faults because the size of the delay faults grows rapidly as increasing the size of the circuit. In order to improve the compactness of the test set, 19-valued logic are derived. Unlike other TG logic systems, 19-valued logic is utilized to generate the robustly hazard-free test pattern. This is achieved by using the basic 5-valued logic, proposed in this work, where the transition with no hazard is

    2007-08-01

    Full Text Available Remote labs are increasingly used in a variety of blended-learning scenarios, with the objective of complementing the work done in real labs. In such cases, the workbenches present in the real labs comprise a set of instruments that may be used over the internet. The lab work to be done by the students may be carried out from any location within or outside the campus, enabling them to carry out their assignments from home or from any other place, at a time of their choice. However, remote experimentation is not necessarily related to students accessing academic labs. Small and medium-size companies may be interested in specialised equipment available in university research labs (e.g. an electron microscope. Alternatively, student skills in various areas may be improved if they are able to work with equipment available in factories or other industry installations. This paper describes a collaboration initiative between the Qimonda SDRAM factory at Vila do Conde, in the vicinity of Porto, and the Faculty of Engineering of the University of Porto (FEUP, whereby an expensive test station used by Qimonda SDRAM factories is remotely accessible to test course students in higher-education institutions.

  11. A study on the development of an automatic fault diagnosis system for testing NPP digital electronic circuits

    International Nuclear Information System (INIS)

    This paper describes a study on the development of an automatic fault diagnosis system for testing digital electronic circuits of nuclear power plants. Compared with the other conventional fault diagnosis systems, the system described in this paper uses Artificial Intelligence technique of model based reasoning and corroboration, which makes fault diagnosis much more efficient. In order to reduce the testing time, an optimal testing set which means a minimal testing set to determine whether or not the circuit is fault-free and to locate the faulty gate was derived. Compared with the testing using an exhaustive testing set, the testing using the optimal testing set makes fault diagnosis much more fast. Since the system diagnoses the circuit boards bases only on input and output signals, it can be further developed for on-line testing. The system was implemented on a microprocessor and was applied for Universal Circuit board testing of the Solid State protection System in nuclear power plants

  13. Equipment qualification research: test program and failure analysis of Class 1E solenoid valves

    International Nuclear Information System (INIS)

    This report documents the results of an equipment qualification research test program performed on ASCO solenoid valves. The valves were subjected to accelerated aging which included 50 Mrd of gamma radiation aging and accelerated thermal aging at 2680F (1310C). All valves performed satisfactorily during the seismic test. Of the seven valves exposed to the LOCA/MSLB simulation, only a metal-seated valve functioned properly throughout without leakage. At the conclusion of the post-LOCA functional testing, a failure analysis was undertaken to determine the failure mode(s) for each valve. The failure analysis included electrical testing of solenoid coils, controlled disassembly of valves, macro- and microscopic examination of internal parts, Shore A durometer testing of elastomeric components, and mass spectrometer analysis of several components. It was concluded that (1) the use of nitrogen to pressurize the valves during thermal aging severely inhibited the aging process since the majority of EPDM components were blanketed in nitrogen, and (2) operational cycling at the elevated thermal aging temperature may have produced stresses not representative of in-service use

  19. Development of Thermal Stress Test Profile for Class 1E Equipment in Main Control Room of a Research Reactor

    International Nuclear Information System (INIS)

    The primary objective of an equipment qualification (EQ) is to demonstrate with reasonable assurance that Class 1E equipment for which a qualified life or condition has been established can perform its safety function without experiencing common-cause failures before, during, and after applicable design basis events (DBEs). For the environmental test of Class 1E equipment installed in the main control room (MCR) of a research reactor, the thermal stress test profile should be developed based on normal and abnormal environmental conditions of the MCR. A thermal stress test profile for Class 1E equipment located in the MCR of a research reactor is developed based on an engineering justification. A set of thermal stress test conditions including temperature, test duration, and number of test cycles is defined considering the specific characteristics of the targeted research reactor. The method used in this study can be applied to develop a thermal stress test profile used for the EQ test to qualify Class 1E equipment installed in the MCR of various research reactors

  20. Development and Testing of a Decision Making Based Method to Adjust Automatically the Harrowing Intensity

    Full Text Available Harrowing is often used to reduce weed competition, generally using a constant intensity across a whole field. The efficacy of weed harrowing in wheat and barley can be optimized, if site-specific conditions of soil, weed infestation and crop growth stage are taken into account. This study aimed to develop and test an algorithm to automatically adjust the harrowing intensity by varying the tine angle and number of passes. The field variability of crop leaf cover, weed density and soil density was acquired with geo-referenced sensors to investigate the harrowing selectivity and crop recovery. Crop leaf cover and weed density were assessed using bispectral cameras through differential images analysis. The draught force of the soil opposite to the direction of travel was measured with electronic load cell sensor connected to a rigid tine mounted in front of the harrow. Optimal harrowing intensity levels were derived in previously implemented experiments, based on the weed control efficacy and yield gain. The assessments of crop leaf cover, weed density and soil density were combined via rules with the aforementioned optimal intensities, in a linguistic fuzzy inference system (LFIS. The system was evaluated in two field experiments that compared constant intensities with variable intensities inferred by the system. A higher weed density reduction could be achieved when the harrowing intensity was not kept constant along the cultivated plot. Varying the intensity tended to reduce the crop leaf cover, though slightly improving crop yield. A real-time intensity adjustment with this system is achievable, if the cameras are attached in the front and at the rear or sides of the harrow.

    The workpiece frames relative to each robot base frame should be known in advance for the proper operation of twin-robot nondestructive testing system. However, when two robots are separated from the workpieces, the twin robots cannot reach the same point to complete the process of workpiece frame positioning. Thus, a new method is proposed to solve the problem of coincidence between workpiece frames. Transformation between two robot base frames is initiated by measuring the coordinate values of three non-collinear calibration points. The relationship between the workpiece frame and that of the slave robot base frame is then determined according to the known transformation of two robot base frames, as well as the relationship between the workpiece frame and that of the master robot base frame. Only one robot is required to actually measure the coordinate values of the calibration points on the workpiece. This requirement is beneficial when one of the robots cannot reach and measure the calibration points. The coordinate values of the calibration points are derived by driving the robot hand to the points and recording the values of top center point(TCP) coordinates. The translation and rotation matrices relate either the two robot base frames or the workpiece and master robot. The coordinated are solved using the measured values of the calibration points according to the Cartesian transformation principle. An optimal method is developed based on exponential mapping of Lie algebra to ensure that the rotation matrix is orthogonal. Experimental results show that this method involves fewer steps, offers significant advantages in terms of operation and time-saving. A method used to synchronize workpiece frames in twin-robot system automatically is presented.

    When used in an air medical setting, medical equipment designed for use in hospitals can fail from the stresses of in-flight use, or they interfere with critical rotor-wing aircraft systems. From January 1989 to June 1992, 34 medical devices, including monitor/defibrillators, infusion pumps, vital-signs monitors, ventilators and infant transport incubators, were tested under extreme conditions of temperature, humidity, altitude and vibration (MIL-STD 810D). Electromagnetic emissions and susceptibility were measured (MIL-STD 461C and 462), and human factors were evaluated. The devices were flight tested in a UH-60 MEDEVAC helicopter. Thirty-two percent of the medical devices failed at least one environmental test, and 91% of the devices failed to meet electromagnetic interference standards. Failures included excess conducted and radiated emissions and susceptibility to radiated emissions. Five (15%) of the devices were judged unsuitable for use in the UH-60 MEDEVAC helicopter. Testing is critical to discover the ability of a medical device to perform in the harsh rotor-wing MEDEVAC environment. Failure of a device or interference with aircraft systems can result in loss of a patient or aircrew. PMID:10127860

  3. Test of large-scale specimens and models as applied to NPP equipment materials

    The paper presents the test results on low-cycle fatigue, crack growth rate and fracture toughness of large-scale specimens and structures, manufactured from steel, widely applied in power engineering industry and used for the production of NPP equipment with VVER-440 and VVER-1000 reactors. The obtained results are compared with available test results of standard specimens and calculation relations, accepted in open-quotes Calculation Norms on Strength.close quotes At the fatigue crack initiation stage the experiments were performed on large-scale specimens of various geometry and configuration, which permitted to define 15X2MFA steel fracture initiation resistance by elastic-plastic deformation of large material volume by homogeneous and inhomogeneous state. Besides the above mentioned specimen tests in the regime of low-cycle loading, the test of models with nozzles were performed and a good correlation of the results on fatigue crack initiation criterium was obtained both with calculated data and standard low-cycle fatigue tests. It was noted that on the Paris part of the fatigue fracture diagram a specimen thickness increase does not influence fatigue crack growth resistance by tests in air both at 20 and 350 degrees C. The estimation of the comparability of the results, obtained on specimens and models was also carried out for this stage of fracture. At the stage of unstable crack growth by static loading the experiments were conducted on specimens of various thickness for 15X2MFA and 15X2NMFA steels and their welded joints, produced by submerged arc welding, in as-produced state (the beginning of service) and after embrittling heat treatment, simulating neutron fluence attack (the end of service). The obtained results give evidence of the possibility of the reliable prediction of structure elements brittle fracture using fracture toughness test results on relatively small standard specimens. 35 refs., 23 figs

  10. Compliance testing of medical diagnostic x-ray equipment: three years experience of a public hospital in western Australia

    International Nuclear Information System (INIS)

    Full text: A formal compliance testing program which began on 1 January 1997 called for all medical and diagnostic x-ray equipment to be tested according to protocols established by the Western Australian Radiological Council. This work describes the impact of the legislation three years post implementation on a major teaching Hospital with 45 x-ray tubes located throughout 37 rooms. Testing is performed prior to scheduled service by licensed compliance testers according to test methods specified in the Western Australian Compliance Testing Workbook, 1997. A dedicated non-invasive x-ray beam analyser is instrumental in accurately determining radiation output parameters of the generator and x-ray tube. Assessment of compliance is determined by a Qualified Expert. Repair and re-testing of non-compliant items is coordinated with service personnel. Notices of non-compliance were received for approximately 60% of the equipment in the Hospital following the equipment' first annual test. Reasons and seriousness of failure varied according to equipment category, test category, equipment use and age. The majority of non-compliance issues were resolved within 90 days. At the end of the third year of testing, approximately 75% of the x-ray units tested met the compliance criteria. The main reasons for non-compliance were found to be design limitations associated with old technology and the current radiation legislation that makes it difficult for older equipment to meet the stringent criteria. The number and categories of failure did not significantly decrease in the second or third years of testing. Exemptions from compliance criteria have been sought for two units on the basis of age and design. Units unable to meet the criteria following several repair attempts or where the cost of repair was deemed not justified, were decommissioned. Formal testing of medical x-ray equipment has demonstrated various non-compliance issues that did not significantly improve during the

  12. Design, construction and testing of replacement nuclear coolant pump stators to meet today's equipment reliability expectations

    International Nuclear Information System (INIS)

    The reliability expectations of equipment and components in today's nuclear power plant are much greater than three or more decades ago when nuclear plants were first constructed due to economic impact of a failure. Very few components in a pressurized water reactor plant can have as much impact of the plants capacity factor as a catastrophic failure of a reactor coolant pump winding. This paper describes the maintenance approach taken by one North American utility in attempt to preclude such failures. The paper will discuss the challenges of the reactor coolant pump application and the enhancements made in the winding design and construction by the supplier to address failure mechanisms so as to better meet present reliability expectations in accordance with dedicated specifications. The paper will also present the in-process and final testing requirements and limits imposed in an attempt to ensure quality of the machine windings, along with selected test results from the stators that have been designed and constructed to these specifications to date.

    Plug-in electric vehicles (PEVs), including battery electric, plug-in hybrid electric, and extended range electric vehicles, are under evaluation by the U.S. Department of Energy's Advanced Vehicle Testing Activity (AVTA) and other various stakeholders to better understand their capability and potential petroleum reduction benefits. PEVs could allow users to significantly improve fuel economy over a standard hybrid electric vehicles, and in some cases, depending on daily driving requirements and vehicle design, PEVs may have the ability to eliminate petroleum consumption entirely for daily vehicle trips. The AVTA is working jointly with the Society of Automotive Engineers (SAE) to assist in the further development of standards necessary for the advancement of PEVs. This report analyzes different methods and available hardware for advanced communications between the electric vehicle supply equipment (EVSE) and the PEV; particularly Power Line Devices and their physical layer. Results of this study are not conclusive, but add to the collective knowledge base in this area to help define further testing that will be necessary for the development of the final recommended SAE communications standard. The Idaho National Laboratory and the Electric Transportation Applications conduct the AVTA for the United States Department of Energy's Vehicle Technologies Program.

  15. Surveillance test and monitoring strategy for the availability improvement of standby equipment using age-dependent model

    International Nuclear Information System (INIS)

    In many cases, the safety of a nuclear power plant greatly depends on the successful operation of specific standby equipment at the time of demand arrival. For the effective management of safety-critical standby equipment, unavailability measures are introduced and widely applied. In this study, we propose an age-dependent unavailability model for standby equipment that considers aging-relevant information, such as the number of actual operations, the elapsed time from installation, and maintenance activities, in an integrated manner. Based on the proposed model, we present two availability enhancement strategies: the Online Monitoring based Inspection Method (OMIM) and the Shortening Surveillance Test Interval Method (SSTIM). In the OMIM, ‘elapsed-time sensitive' elements are monitored, without actual operation, at the differentiated monitoring interval with the help of sensing devices. For the remaining parts of the elements, actual testing is performed with an adaptive interval for each standby turn by the SSTIM. The effectiveness of the proposed enhancement schemes is demonstrated through a case study for the motor-operated valve (MOV). It is our belief that the proposed schemes can be widely applied in areas such as equipment testing, maintenance strategies, dynamic probabilistic safety assessment (PSA), and risk-informed regulations. - Highlights: • An age-dependent unavailability model for standby equipment was investigated. • An Online Monitoring-based Inspection Method was suggested. • Changing the test interval for each standby turn was suggested. • The effectiveness of the suggested methods was analyzed quantitatively

    Dewatering of ultra-fine (minus 150 {micro}m) coal slurry to less than 20% moisture is difficult using the conventional dewatering techniques. The main objective of the project was to evaluate a novel surface modification technique, which utilizes the synergistic effect of metal ions and surfactants in combination for the dewatering of ultra-fine clean-coal slurries using various dewatering techniques on a proof-of-concept (POC) scale of 0.5 to 2 tons per hour. The addition of conventional reagents and the application of coal surface modification technique were evaluated using vacuum filtration, hyperbaric (pressure) filtration, ceramic plate filtration and screen-bowl centrifuge techniques. The laboratory and pilot-scale dewatering studies were conducted using the fine-size, clean-coal slurry produced in the column flotation circuit at the Powell Mountain Coal Company, St. Charles, VA. The pilot-scale studies were conducted at the Mayflower preparation plant in St. Charles, VA. The program consisted of nine tasks, namely, Task 1--Project Work Planning, Task 2--Laboratory Testing, Task 3--Engineering Design, Task 4--Procurement and Fabrication, Task 5--Installation and Shakedown, Task 6--System Operation, Task 7--Process Evaluation, Task 8--Equipment Removal, and Task 9--Reporting.

    Within the context of liberalisation of the energy market, hydroelectricity remains a first class source of clean and renewable energy. Combining the growing demand of energy, its increasing value and the appreciation associated to the sustainable development, low head sites formerly considered as non-profitable are now exploitable. Bulb turbines likely to equip such sites are traditionally developed on model using right angle transmission leading to piers enlargement for power take off shaft passage, thus restricting possibilities to have fully homologous hydraulic passages. Aiming to sustain good quality development on fully homologous scale model of bulb turbines, the Hydraulic Machines Laboratory (LAMH) of Laval University has developed a brake with an enhanced power to weight ratio. This powerful brake is small enough to be located in the bulb shell while dissipating power without mandatory test head reduction. This paper first presents the basic technology of this brake and its application. Then both its main performance capabilities and dimensional characteristics will be detailed. The instrumentation used to perform accurate measurements will be finally presented

  6. SECOND GENERATION EXPERIMENTAL EQUIPMENT DESIGN TO SUPPORT VOLOXIDATION TESTING AT INL

    International Nuclear Information System (INIS)

    Voloxidation is a potential head-end process used prior to aqueous or pyrochemical spent-oxide-fuel treatment. The spent oxide fuel is heated to an elevated temperature in oxygen or air to promote separation of the fuel from the cladding as well as volatize the fission products. The Idaho National Laboratory (INL) and the Korea Atomic Energy Research Institute (KAERI) have been collaborating on voloxidation research through a joint International Nuclear Energy Research Initiative (I-NERI). A new furnace and off-gas trapping system (OTS) with enhanced capability was necessary to perform further testing. The design criteria for the OTS were jointly agreed upon by INL and KAERI. First, the equipment must accommodate the use of spent nuclear fuel and be capable of operating in the Hot Fuel Examination Facility (HFEF) at the INL. This primarily means the furnace and OTS must be remotely operational and maintainable. The system requires special filters and distinctive temperature zones so that the fission products can be uniquely captured. The OTS must be sealed to maximize the amount of fission products captured. Finally, to accommodate the largest range of operating conditions, the OTS must be capable of handling high temperatures and various oxidizing environments. The constructed system utilizes a vertical split-tube furnace with four independently controlled zones. One zone is capable of reaching 1200 C to promote the release of volatile fission products. The three additional zones that capture fission products can be controlled to operate between 100-1100 C. A detailed description of the OTS will be presented as well as some initial background information on high temperature seal options

    In Sweden some principles to reduce the radon concentration in drinking water were tested in the beginning of the 1980s. Spray aeration under atmospheric pressure, diffused bubble aeration, aeration in the pressure tank and different combinations of these principles were studied. Aeration in the drill hole and adsorption on granulated activated char-coal were also tested. The best results, about 70 % reduction, were obtained with aeration in the pressure tank with a spray system combined with diffused air bubbling. The Oerebro project in the beginning of the 1990s included on site testing of five different aeration solutions: Aeration in the drill hole, aeration in the storage tank, ejector aeration, shallow tray aeration and packed column aeration. The radon removal efficiency varied between 20 % and 99 %. In 1994 a study intended to test the radon removal capacity of different water treatment equipment was performed. Six units of radon separators were included but most of the tested equipment was installed for other water treatment purposes. The performed measurements showed that the only types of equipment that reduce the radon concentration efficiently are radon separators and reverse osmosis filters. The radon removal capacity of the radon separators varied between 23 % and 97 %. In 1996 the nine most common radon separators on the Swedish market were tested. The results showed that the tested radon removal equipment worked well, although the technical quality and chosen technical solutions were not always the best. The radon removal capacity of the units participating in this test was in most cases between 96 and 99 %. In some cases the capacity exceeded 99 %. In order to reach this radon removal capacity the water must be recirculated in a storage tank under atmospheric pressure.

  10. Application of automatic inspection system to nondestructive test of heat transfer tubes of primary pressurized water cooler in the high temperature engineering test reactor. Joint research

    International Nuclear Information System (INIS)

    Heat transfer tubes of a primary pressurized water cooled (PPWC) in the high temperature engineering test reactor (HTTR) form the reactor pressure boundary of the primary coolant, therefore are important from the viewpoint of safety. To establish inspection techniques for the heat transfer tubes of the PPWC, an automatic inspection system was developed. The system employs a bobbin coil probe, a rotating probe for eddy current testing (ECT) and a rotating probe for ultrasonic testing (UT). Nondestructive test of a half of the heat transfer tubes of the PPWC was carried out by the automatic inspection system during reactor shutdown period of the HTTR (about 55% in the maximum reactor power in this paper). The nondestructive test results showed that the maximum signal-to-noise ratio was 1.8 in ECT. Pattern and phase of Lissajous wave, which were obtained for the heat transfer tube of the PPWC, were different from those obtained for the artificially defected tube. In UT echo amplitude of the PPWC tubes inspected was lower than 20% of distance-amplitude calibration curve. Thus, it was confirmed that there was no defect in depth, which was more than the detecting standard of the probes, on the outer surface of the heat transfer tubes of the PPWC inspected. (author)

  11. Test blanket module maintenance operations between port plug and ancillary equipment unit in ITER

    International Nuclear Information System (INIS)

    In collaboration between the FZK and KFKI-RMKI, in the frame of the activities of the EU Breeder Blanket Programme a concept for test blanket module (TBM) integration, maintenance schedules and all required special purpose equipments has been developed. During the first 10 years of ITER operation four different plasma scenarios will be used. Hence it will be possible to investigate the characteristics (e.g. tritium breeding performance) of different TBM concepts which will be installed during operation for the different phases of ITER operation in the equatorial ports 2, 16 and 18. In every port two TBMs will be accommodated, in the port 16 will be the European helium-cooled pebble bed blanket. In different phases of ITER operation different TBMs will be used. Therefore a complex maintenance process is necessary for the exchange of TBMs. Two TBMs are mounted onto one common frame, into a port plug (PP), which offers a standardised interface to the vacuum vessel (VV). It is cantilevered with a flange to VV port extension. This attachment system is the same in every equatorial port, so the exchange process of this structure with the TBMs is also the standard operation of ITER. Several components of the helium cooling system of the EU breeder modules, valves, pipes, gas mixers, thermal sleeves, pipes for tritium extraction, measurement system are integrated into the ancillary equipment unit (AEU), which during the operation will connect the port plug to the subsystems. The bigger part of the AEU is accommodated in the port cell and the rest part of it is penetrated into the interspace inside the bioshield and reach the back plane of the installed PP. The remote handling operations for connection/disconnection of an interface between the PP of the EU-TBMs and the AEU are investigated with the goal to reach a quick and simple TBM exchange procedure. The current design of the EU-TBMs foresees up to 18 supply lines for both TBMs. These lines have to be connected here. A

  13. Dose measurement. Testing methods for quality control of the X-ray generating systems of diagnostic equipment

    International Nuclear Information System (INIS)

    Testing characteristics for definition of the technical reliability of equipment can be obtained by dose measurements. Requirements with regard to accuracy of exposure of the imaging system and limitation of the patient's exposure can be defined by means of tolerance margins or dose limits. This survey presents only those testing methods that require dose measurements and that cannot be done with other quantities measured. Proposals are presented for a standardization of these testing methods, taking into account aspects of practical feasibility, measuring accuracy, and cost reduction. The testing characteristics are determined, tolerance margins are given and discussed, and the information obtained is evaluated. (orig./DG)

    2012-08-01

    Full Text Available Abstract Background The twelve-item Self-Report Habit Index (SRHI is the most popular measure of energy-balance related habits. This measure characterises habit by automatic activation, behavioural frequency, and relevance to self-identity. Previous empirical research suggests that the SRHI may be abbreviated with no losses in reliability or predictive utility. Drawing on recent theorising suggesting that automaticity is the ‘active ingredient’ of habit-behaviour relationships, we tested whether an automaticity-specific SRHI subscale could capture habit-based behaviour patterns in self-report data. Methods A content validity task was undertaken to identify a subset of automaticity indicators within the SRHI. The reliability, convergent validity and predictive validity of the automaticity item subset was subsequently tested in secondary analyses of all previous SRHI applications, identified via systematic review, and in primary analyses of four raw datasets relating to energy‐balance relevant behaviours (inactive travel, active travel, snacking, and alcohol consumption. Results A four-item automaticity subscale (the ‘Self-Report Behavioural Automaticity Index’; ‘SRBAI’ was found to be reliable and sensitive to two hypothesised effects of habit on behaviour: a habit-behaviour correlation, and a moderating effect of habit on the intention-behaviour relationship. Conclusion The SRBAI offers a parsimonious measure that adequately captures habitual behaviour patterns. The SRBAI may be of particular utility in predicting future behaviour and in studies tracking habit formation or disruption.

    Corn paper pot seedling transplanting technology is a new type cultivation method that can effectively increase accumulated temperature, resist drought, prevent disasters and obtain high yields; issues such as low and unstable grain yield due to shortage of water resources, drought and frequent plant diseases and insect pests in spring dry farming conditions. Conventional corn paper pot seedling transplanting operations are conducted on a manual basis, which generates features such as large labor intensity, low working efficiency, poor working quality, low degree of standardization and farming seasons cannot be grasped and so forth; the conventional operations are not beneficial to large area production operation, which seriously restricts the promotion and application of corn paper pot seedling transplanting technology. Therefore, mechanized corn seedling transplanting is an imperative trend. At present, corn paper pot seedling transplanting technology and methods as well as relevant machinery equipment are not available. Existing transplanting machineries in Europe, US, Japan and South Korea are mainly used for flowers, vegetables and economic crops. As per planting methods, transplanting machineries can be divided into: clamp type transplanters, chain clamp type transplanters, hanging cup type transplanters, seedling-guiding tube type transplanters and flexible disc type transplanters. However, all of such transplanters have some defects that cannot be overcome. A new type of full-automatic paper pot corn seedling transplanter was researched and developed based on the research of integrating the advantages of pot seedling and bare-rooted seedling, the principle of flexible disc type transplanting in combination with automation control and hydraulically powered seedling collecting, seedling rejecting and seedling supplying mechanism. The transplanter is composed of a seedling transporting and selecting transmission case, an automatic seeding system, a

    Test flights were conducted to evaluate the capability of Differential Global Positioning System (DGPS) to provide the accuracy and integrity required for International Civil Aviation Organization (ICAO) Category (CAT) 3 precision approach and landings. These test flights were part of a Federal Aviation Administration (FAA) program to evaluate the technical feasibility of using DGPS based technology for CAT 3 precision approach and landing applications. A United Airlines Boeing 737-300 (N304UA) was equipped with DGPS receiving equipment and additional computing capability provided by Stanford University. The test flights were conducted at NASA Ames Research Center's Crows Landing Flight Facility, Crows Landing, California. The flight test evaluation was based on completing 100 approaches and autolandings; 90 touch and go, and 10 terminating with a full stop. Two types of accuracy requirements were evaluated: 1) Total system error, based on the Required Navigation Performance (RNP), and 2) Navigation sensor error, based on ICAO requirements for the Microwave Landing System (MLS). All of the approaches and autolandings were evaluated against ground truth reference data provided by a laser tracker. Analysis of these approaches and autolandings shows that the Stanford University/United Airlines system met the requirements for a successful approach and autolanding 98 out of 100 approaches and autolandings, based on the total system error requirements as specified in the FAA CAT 3 Level 2 Flight Test Plan.

    International Nuclear Information System (INIS)

    The hot cell laboratory at SCN (Romanian acronym for Nuclear Research Branch) has a set of typical methods for post-irradiation examination (PIE) of nuclear fuel and materials. However, to obtain relevant information concerning the safety and reliability of nuclear fuel and materials in nuclear power plants (NPP), three new equipment were installed in the hot cell laboratory: - Leica TELATOM 4 Remote Controlled Inverted Widefield Metallographic Microscope; - Tescan MIRA II LMU CS High Resolution Schottky Field Emission Variable Pressure Scanning Electron Microscope. - DYNA DM1007 Milling Machine with Numerical Process Control System for Preparation of Radioactive Samples. The funds for purchasing these equipment were obtained by SCN NUCLAB project as a result of national competition within the framework of National Program for Research, Development and Innovation. The overall objective of the NUCLAB project is to modernize the extant laboratory by endowment with performing equipment to increase the research capacity and the capability to offer scientific and technological services for nuclear industry. The TELATOM 4 metallographic microscope replaced the old LEITZ MM5RT optical microscope. Prior to installing the new microscope into a steel hot cell, the old microscope was removed and the hot cell was refurbished. The MIRA II SEM will be installed in a lead hot cell and The DYNA DM1007 Milling Machine will be installed in a heavy concrete hot cell. The paper describes the basic parameters of the three new pieces of equipment and some results from irradiated CANDU fuel and unirradiated CANDU pressure tube. (authors)

    Full Text Available A key issue in software testing is the actual generation of test data from program input domain. Obviously, more accurate input domain is, more efficient test generation is. This paper presents a path-orientedautomatic random testing method based on double constraint propagation. For a given path, its domain can be reduced by splitting an input variable domain and executing a double constraint propagation algorithm. Moreover, a random test data generator is developed according to the reduced path domain and the test experiments are conducted on a number of programs. Experimental results show that the methodgets more accurate path domain than PRT (path-oriented random testing approach, and random testing efficiency can thus be enhanced by using the proposed method.

  7. Automatic Stress Testing of Multi-tier Systems by Dynamic Bottleneck Switch Generation

    Science.gov (United States)

    Casale, Giuliano; Kalbasi, Amir; Krishnamurthy, Diwakar; Rolia, Jerry

    The performance of multi-tier systems is known to be significantly degraded by workloads that place bursty service demands on system resources. Burstiness can cause queueing delays, oversubscribe limited threading resources, and even cause dynamic bottleneck switches between resources. Thus, there is need for a methodology to create benchmarks with controlled burstiness and bottleneck switches to evaluate their impact on system performance. We tackle this problem using a model-based technique for the automatic and controlled generation of bursty benchmarks. Markov models are constructed in an automated manner to model the distribution of service demands placed by sessions of a given system on various system resources. The models are then used to derive session submission policies that result in user-specified levels of service demand burstiness for resources at the different tiers in a system. Our approach can also predict under what conditions these policies can create dynamic bottleneck switching among resources. A case study using a three-tier TPC-W testbed shows that our method is able to control and predict burstiness for session service demands. Further, results from the study demonstrate that our approach was able to inject controlled bottleneck switches. Experiments show that these bottleneck switches cause dramatic latency and throughput degradations that are not shown by the same session mix with non-bursty conditions.

  8. Design of electronic measurement and quench detection equipment for the Current Lead Test facility Karlsruhe (CuLTKa)

    International Nuclear Information System (INIS)

    The Current Lead Test facility Karlsruhe (CuLTKa) is under construction at the Karlsruhe Institute of Technology (KIT) to perform acceptance tests of high temperature superconductor (HTS) current leads (CL). CuLTKa is in progress and present planning expects the completion in 2013. The data acquisition system is based on a modular design with electronic measurement and monitoring equipment covering a test voltage of 50 kV DC against ground. It provides plug-in units which enable temperature and voltage measurement at high voltage potential and in addition quench detection units which detect a loss of superconductivity reliably and quickly to avoid damage of the superconducting device under test. Prototype units for quench detection, temperature and voltage measurement have been successfully tested. Six temperature measurement units are already in use in the KIT test facility TOSKA and operated reliably during the acceptance tests of the HTS current leads for Wendelstein 7-X (W7-X) in 2011/2012. CuLTKa will be used first for 26 current leads which will be built in KIT for the fusion experiment JT-60SA. The present paper gives an overview of the design of the electronic measurement and quench detection equipment

    Full Text Available The main aim of this paper is to generate test cases from the use cases. In the real-time scenario we have to face several issues like inaccuracy, ambiguity, and incompleteness in requirements this is because the requirements are not properly updated after various change requests. This will reduce the quality of test cases. To overcome these problems we develop a solution which generates test cases at the early stages of system development life cycle which captures maximum number of requirements. As requirements are best captured by use cases our focus lies on generating test cases from use case diagrams.

    2010-01-01

    For large, complex software systems, it is typically impossible in terms of time and cost to reliably test the application in all possible execution states and configurations before releasing it into production. One proposed way of addressing this problem has been to continue testing and analysis of the application in the field, after it has been deployed. A practical limitation of many such automated approaches is the potentially high performance overhead incurred by the necessary instrumentation. However, it may be possible to reduce this overhead by selecting test cases and performing analysis only in previously-unseen application states, thus reducing the number of redundant tests and analyses that are run. Solutions for fault detection, model checking, security testing, and fault localization in deployed software may all benefit from a technique that ignores application states that have already been tested or explored. In this paper, we present a solution that ensures that deployment environment tests are only executed in states that the application has not previously encountered. In addition to discussing our implementation, we present the results of an empirical study that demonstrates its effectiveness, and explain how the new approach can be generalized to assist other automated testing and analysis techniques intended for the deployment environment.

  14. An efficient method for seismic assessment of the existing equipment checked through testings on a high power seismic facility

    International Nuclear Information System (INIS)

    The increasing power demand is a characteristic social requirement in the industrial countries. The interruption over a considerable duration of the power supply from power plants damaged by a major earthquake could lead to disastrous consequence for all of activities in a given region. Presently, the quasi-totality of electrotechnical, electronic and automation equipment are conceived and manufactured with no precaution concerning the seismic risks. All but equipment for nuclear power plants are not certified and even in nuclear power plants the problems of qualification of very massive equipment mounted at the operation site are difficult. in this paper a rapid and economically efficient method is presented for assessing the mechanical stresses induced by an earthquake in the critical sections of a column type equipment. The stresses computed with this method were compared with those measured directly in a seismic testing in the case of high voltage switch, carried out on a high power vibratory table. The results of the comparison confirm the economical efficiency of the described method. (Author) 6 Figs., 1 Tab., 4 Refs

    A method using ultrasonic devices for on-line measurement of oil coiled tubing was proposed. The principle of ultrasonic testing was analyzed. Then, the structure of the system consisting of mechanical system, coupling system, measuring system, control system and system software was determinated. Based on the analysis of technology requirement, measuring technique in which the coiled tubing did not rotate and the probe was static was chosen. The ultrasonic testing probes were triggered in turn. After signal sampling, digital filtering and A / D conversion signal processing, the received echo signals were sent to computer. Through analyzing and accounting, the test results were obtained. Based on VC++.net, A-type ultrasonic and C-type ultrasonic display software and the inspection data processing software were developed. Using Windows programming technology, the software structure and function library were totally open. Therefore, secondary development can be carried out conveniently. Based on the experimental studies, coiled tubing's ultrasonic testing system is developed. The testing results show that the system has specific advantages such as high-adaptation, highefficiency, high- stability, high reliability and can meet the need of the users. The ultrasonic testing technologies proposed in this paper can be applied extensively to other tubes.

    Various bioassays have been applied to evaluate safety of environmental water and treated water. The umu test is a method for the detection of genotoxicity by using SOS function of Salmonella typhimurium. The protocol of the umu test is divided into 5 phases, (1) pre-incubation of test strain, (2) addition of samples, (3) induction of umuC gene, (4) {beta}-galactosidase enzymatic reaction, and (5) measurement of absorption in a spectrophotometry and calculation of the activity. In usual procedure, all phases are performed in batch-type reactors, using test tubes. In this study, we tried to develop the device of flow-injection style to perform the umu test automatically. The culture was flowed through a tube and added samples by using a rotary pump. The various conditions were investigated and modified for detection of genotoxicity of AF-2. Even after 24hr of incubation under control, test strain showed activity. Within 1.5hr, the test strain was most active at 36degC and longer than 2.0hr, it was so at 37degC. At each phases some more conditions have been investigated, and we suggest that new device of flow-injection style could be effective to screen or monitor the genotoxicity of environmental water. 10 refs., 10 figs.

    Hyperglycaemia in hospitalized patients is a common and costly health care problem. The GlucoTab system is a mobile workflow and decision support system, aiming to facilitate efficient and safe glycemic control of non-critically ill patients. Being a medical device, the GlucoTab requires extensive and reproducible testing. A framework for high-volume, reproducible and automated system testing of the GlucoTab system was set up applying several Open Source tools for test automation and system time handling. The REACTION insulin titration protocol was investigated in a paper-based clinical trial (PBCT). In order to validate the GlucoTab system, data from this trial was used for simulation and system tests. In total, 1190 decision support action points were identified and simulated. Four data points (0.3%) resulted in a GlucoTab system error caused by a defective implementation. In 144 data points (12.1%), calculation errors of physicians and nurses in the PBCT were detected. The test framework was able to verify manual calculation of insulin doses and detect relatively many user errors and workflow anomalies in the PBCT data. This shows the high potential of the electronic decision support application to improve safety of implementation of an insulin titration protocol and workflow management system in clinical wards.

    The water-consuming amount in a long-term astro-navigation is large. In order to reduce the burden of water supply from Earth ground, the space station needs to resolve the problems of water supply. For this reason, the recovery and regeneration of urine solution of spacemen, and its utilization possess a key importance. Many investigations on this aspect have been reported. Our research based on "biological absorption-purification-UV photocatalytic oxidation" techniques with a relevant treating equipment that for a comprehensive treatment to fresh urine of spacemen has been created. In this equipment, the urine solution was used as the nutrient solution for the biological parts in ecological life ensurant system, after absorbing the nutrient, it was decomposed, metabolized and purified in some distance, and created a favorable condition for the follow-up oxidation treatment by UV-Photocatalytic Oxidation.

    Parenteral drug products are protected by appropriate primary packaging to protect against environmental factors, including potential microbial contamination during shelf life duration. The most commonly used CCS configuration for parenteral drug products is the glass vial, sealed with a rubber stopper and an aluminum crimp cap. In combination with an adequately designed and controlled aseptic fill/finish processes, a well-designed and characterized capping process is indispensable to ensure product quality and integrity and to minimize rejections during the manufacturing process. In this review, the health authority requirements and expectations related to container closure system quality and container closure integrity are summarized. The pharmaceutical vial, the rubber stopper, and the crimp cap are described. Different capping techniques are critically compared: The most common capping equipment with a rotating capping plate produces the lowest amount of particle. The strength and challenges of methods to control the capping process are discussed. The residual seal force method can characterize the capping process independent of the used capping equipment or CCS. We analyze the root causes of several cosmetic defects associated with the vial capping process. PMID:26654992

    Characterisation and quantification of emphysema are necessary for planning of local treatment and monitoring. Sensitive, easy to measure, and stable parameters have to be established and their relation to the well-known pulmonary function testing (PFT) has to be investigated. A retrospective analysis of 221 nonenhanced thin-section MDCT with a corresponding PFT was carried out, with a subgroup analysis in 102 COPD stage III+IV, 44 COPD stage 0, and 33 investigations into interstitial lung disease (ILD). The in-house YACTA software was used for automatic quantification of lung and emphysema volume [l], emphysema index, mean lung density (MLD [HU]) and 15{sup th} percentile [HU]. CT-derived lung volume is significantly smaller in ILD (3.8) and larger in COPD (7.2) than in controls (5.9, p<0.0001). Emphysema volume and index are significantly higher in COPD than in controls (3.2 vs. 0.5, p<0.0001, 45% vs. 8%, p<0.0001). MLD and 15{sup th} percentile are significantly smaller in COPD (-877/-985, p<0.0001) and significantly higher in ILD (-777, p<0.0006/-914, p<0.0001) than in controls (-829/-935). A relevant amount of COPD patients apparently do not suffer from emphysema, while controls who do not fulfil PFT criteria for COPD also demonstrate CT features of emphysema. Automatic quantification of thin-section CT delivers convincing parameters and ranges that are able to differentiate among emphysema, control and ILD. An emphysema index of lower 20%, MLD higher than -850, and 15{sup th} percentile lower than -950 might be regarded as normal (thin-section, nonenhanced, B40, YACTA). These ranges might be helpful in the judgement of individual measures. (orig.)

    The use of radiographic phantoms specifically designed to evaluate the operation of the radiographic equipment lets the study of the image quality obtained by this equipment in an objective way. In digital radiographic equipment, the analysis of the image quality can be computerized because the acquisition of the image is possible in different technologies that are, computerized radiography or phosphor plate and direct radiography or detector. In case of film-screen equipment s this analysis could be applied digitalising the image in a professional scanner. In this work we have shown an application to assess automatically the constancy quality image in the image chain of the radiographic equipment s. This application is integrated by designed radiographic phantoms which are adapted to conventional, dental equipment s and specific developed software for the automatic evaluation of the phantom image quality. The software is based on digital image processing techniques that let the automatic detection of the different phantom tests by edge detector, morphological operators, threshold histogram techniques... etc. The utility developed is enough sensitive to the radiographic equipment of operating conditions of voltage (kV) and charge (m As). It is a friendly user programme connected with a data base of the hospital or clinic where it has been used.

  18. Experimental study on properties of high cycle thermal fatigue. Outline and test plan of high cycle fatigue test equipment on sodium

    International Nuclear Information System (INIS)

    At a nuclear power plant, where fluids of high and low temperature flow into each other, it is necessary to prevent structural failure damage caused by high cycle thermal fatigue (thermal striping phenomenon). High cycle fatigue test equipment on thermal can be develop by modifying the thermal transient test facility for structure (TTS) in order to clarify the effect of temperature fluctuation induced by the thermal striping phenomenon on crack initiation and their propagation behavior. The test equipment has the following characteristic. (1) Fluid is controlled by a circulation pump, and by continuously changing the flow quantity ratio of high and low temperature Sodium, sinusoidal temperature fluctuations at various period of the test samples can be taken. (2) Mixing is done by the jet flow mix, thus it can generate axisymmetric temperature fluctuations by accelerating the mixing process of high and low temperature Sodium. (3) It can also control the temperature fluctuation, in which short and long term changes are superimposed. (4) Because the test sample cylinder is hollow, analysis of thermal stress and data from crack initiation to crack propagation can easily be obtained. Sinusoidal temperature fluctuations, random temperature fluctuations, and strength testing of the weld zone by test samples made of stainless steel are planned in the next stage. (author)

  19. Ultrasound testing of the penetration of automatic welds of tubes on plates with using electron beams

    International Nuclear Information System (INIS)

    This control technique was developed within the scope of a D.G.R.S.T. study on electron beam welding of tubes to exchanger plates with a portable gun. The device developed is easy to use and enables the control to be carried out according to various techniques with good accuracy: used for acceptance tests merely for testing that a penetration to specification is reached and by working by 'hit and miss', it permits high work rates; used as a quality control system, it enables recordings to be made which accurately record the shape of the weld bead root, the penetration depth (and any possible weld compactness faults). The work rate is then reduced. Of course, the combined use of both techniques is possible, even advisable in some cases. For example, it is possible to imagine a total control by the first technique and an additional exploration by the second one. The exploration can then be to a percentage fixed by agreement or better, form a supplementary examination orientated according to the results obtained during the short examination

    1984-01-01

    The Digital Integrated Automatic Landing System (DIALS) is discussed. The DIALS is a modern control theory design performing all the maneuver modes associated with current autoland systems: localizer capture and track, glideslope capture and track, decrab, and flare. The DIALS is an integrated full-state feedback system which was designed using direct-digital methods. The DIALS uses standard aircraft sensors and the digital Microwave Landing System (MLS) signals as measurements. It consists of separately designed longitudinal and lateral channels although some cross-coupling variables are fed between channels for improved state estimates and trajectory commands. The DIALS was implemented within the 16-bit fixed-point flight computers of the ATOPS research aircraft, a small twin jet commercial transport outfitted with a second research cockpit and a fly-by-wire system. The DIALS became the first modern control theory design to be successfully flight tested on a commercial-type aircraft. Flight tests were conducted in late 1981 using a wide coverage MLS on Runway 22 at Wallops Flight Center. All the modes were exercised including the capture and track of steep glidescopes up to 5 degrees.

  1. Equipment to detect bad isolator in hard disk drive testing process

    2014-09-01

    Full Text Available With increasing data capacity of hard disk drive (HDD today, the testing time of a hard disk drive becames longer. It takes approximately 25 - 30 hours. Vibrations during HDD testing process significantly contribute to testing errors. Isolator and pocket slot were used to reduce the vibration. The physical property of isolators was charged, that led to the results of HDD testing. Because of the error, the testing process needs to be redone. As a result, the testing time is extended. This research developed a system to detect isolator function using “Ariduino Due” microcontroller along with “Micro-electromechanical System – MEMS” accelerator sensor. For the precise analysis, the statistical method called t test was used to group isolators by their functioning conditions. It was found that, the measured vibration amplitude in any direction canbe used as the criteria for identifying the isolator conditions. This detective system can determine the bad isolator at early stage before the exceeding vibration will affect the testing process.

    2012-01-01

    Aimed at many weaknesses in the LIN bus testing system like weak compatibility,absent malfunction definitions, difficulties in designing the test equipment and low degree of automation,a new LIN bus automatic test system was proposed based on the LIN description file. The system hardware design consists of upper PC and PIC18F6520 mircocotroller.

  7. Automatic sequences

    CERN Document Server

    Haeseler, Friedrich

    2003-01-01

    Automatic sequences are sequences which are produced by a finite automaton. Although they are not random they may look as being random. They are complicated, in the sense of not being not ultimately periodic, they may look rather complicated, in the sense that it may not be easy to name the rule by which the sequence is generated, however there exists a rule which generates the sequence. The concept automatic sequences has special applications in algebra, number theory, finite automata and formal languages, combinatorics on words. The text deals with different aspects of automatic sequences, in particular:· a general introduction to automatic sequences· the basic (combinatorial) properties of automatic sequences· the algebraic approach to automatic sequences· geometric objects related to automatic sequences.

    We have designed and fabricated an anatomically accurate human head phantom that is capable of generating realistic electric scalp potential patterns. This phantom was developed for performance evaluation of new electroencephalography (EEG) caps, hardware, and measurement techniques that are designed for environments high in electromagnetic and mechanical noise. The phantom was fabricated using conductive composite materials that mimic the electrical and mechanical properties of scalp, skull, and brain. The phantom prototype was calibrated and testing was conducted using a 32-electrode EEG cap. Test results show that the phantom is able to generate diverse scalp potential patterns using a finite number of dipole antennas internal to the phantom. This phantom design could provide a valuable test platform for wearable EEG technology. PMID:22911537

    ZHANG Zhi-yi; WANG Gong-xian; WANG Yu

    2009-01-01

    In order to qualify shock resistance performance of shipboard equipments and simulate real underwater explosion environment, a novel dual-puise shock test machine is proposed. The new machine will increase testing capability and meet special shock testing requirement. Two key parts of the machine, the velocity generator and the shock pulse regulator, play an important role in producing the positive acceleration pulse and the succeeding negative acceleration pulse, respectively. The generated dual-pulse shock for test articles is in conformity with an anti-shock test specification. Based on the impact theory, a nonlinear dynamic model of the hydraulically-actuated test machine is established with thorough analysis on its mechanism that involves conversion of gas potential energy and dissipation of kinetic energy. Simulation results have demonstrated that the proposed machine is able to produce a double-pulse acceleration shock in the time domain or a desired shock response spectrum in the frequency domain, which sets up a base for the construction of the machine.

  13. Fully automatic quantitative assessment of emphysema in computed tomography: comparison with pulmonary function testing and normal values

    International Nuclear Information System (INIS)

    Characterisation and quantification of emphysema are necessary for planning of local treatment and monitoring. Sensitive, easy to measure, and stable parameters have to be established and their relation to the well-known pulmonary function testing (PFT) has to be investigated. A retrospective analysis of 221 nonenhanced thin-section MDCT with a corresponding PFT was carried out, with a subgroup analysis in 102 COPD stage III+IV, 44 COPD stage 0, and 33 investigations into interstitial lung disease (ILD). The in-house YACTA software was used for automatic quantification of lung and emphysema volume [l], emphysema index, mean lung density (MLD [HU]) and 15th percentile [HU]. CT-derived lung volume is significantly smaller in ILD (3.8) and larger in COPD (7.2) than in controls (5.9, pth percentile are significantly smaller in COPD (-877/-985, pth percentile lower than -950 might be regarded as normal (thin-section, nonenhanced, B40, YACTA). These ranges might be helpful in the judgement of individual measures. (orig.)

  17. Ten years experience in acceptance testing of diagnostic radiology equipment in Hungary

    International Nuclear Information System (INIS)

    The EURATOM directive for the radiation protection of patients, which declares the mandatory evaluation of the performance of diagnostic X-ray machines, took effect in 1997. In Hungary, this became a harmonized act, the 31/2001. (X. 3.) decree of the Minister of Health. The most highlighted segment of the evaluation of technical performance is acceptance testing. The NRIRR Department of Radiohygiene performs acceptance tests since 2002. From then on we have performed more than 400 examinations on different modalities such as radiographic, fluoroscopic, DSA, mammographic, CT and dental panoramic X-rays. The tests were performed according to IEC = EN = MSZ EN international, European and at the same time Hungarian standards. This presentation discusses our experience and gives a comprehensive overview of the examinations by the evaluation of the measurement data. Our results show the importance of testing, done independently from the manufacturer and installer: in est. 25 % of the cases overall we have found inadequacies which required remedial action on the part of the service

    2012-08-01

    The UltraBattery Retrofit Project DP1.8 and Carbon Enriched Project C3, performed by ECOtality North America (ECOtality) and funded by the U.S. Department of Energy and the Advanced Lead Acid Battery Consortium (ALABC), are established to demonstrate the suitability of advanced lead battery technology in hybrid electrical vehicles (HEVs). A profile, termed the “Simulated Honda Civic HEV Profile” (SHCHEVP) has been developed in Project DP1.8 in order to provide reproducible laboratory evaluations of different battery types under real-world HEV conditions. The cycle is based on the Urban Dynamometer Driving Schedule and Highway Fuel Economy Test cycles and simulates operation of a battery pack in a Honda Civic HEV. One pass through the SHCHEVP takes 2,140 seconds and simulates 17.7 miles of driving. A complete nickel metal hydride (NiMH) battery pack was removed from a Honda Civic HEV and operated under SHCHEVP to validate the profile. The voltage behavior and energy balance of the battery during this operation was virtually the same as that displayed by the battery when in the Honda Civic operating on the dynamometer under the Urban Dynamometer Driving Schedule and Highway Fuel Economy Test cycles, thus confirming the efficacy of the simulated profile. An important objective of the project has been to benchmark the performance of the UltraBatteries manufactured by both Furukawa Battery Co., Ltd., Japan (Furakawa) and East Penn Manufacturing Co., Inc. (East Penn). Accordingly, UltraBattery packs from both Furakawa and East Penn have been characterized under a range of conditions. Resistance measurements and capacity tests at various rates show that both battery types are very similar in performance. Both technologies, as well as a standard lead-acid module (included for baseline data), were evaluated under a simple HEV screening test. Both Furakawa and East Penn UltraBattery packs operated for over 32,000 HEV cycles, with minimal loss in performance; whereas the

  4. Device for Testing and Calibrating Equipment for Monitoring Atmospheric Contamination by Aerosols

    International Nuclear Information System (INIS)

    A device for aerosol production and entrainment has been designed and built at the Physics Laboratory of the Radiation Protection Section of the Nuclear Studies Centre in Fontenay-aux-Roses for use in experiments with and calibration of various instruments for monitoring atmospheric contamination by radioactive aerosols. The paper describes the device for aerosol production and diffusion and refers to a number of experiments which illustrate its use. The unit consists of an aerosol generator which disperses inside a containment aerosols produced by drying a saline solution in dry air. The aerosols in the homogenization container have a definite and reproducible particle size. The concentration of natural daughter products of radon can be varied within certain limits. The first checks of aerosol particle size were made with a cascade impactor. Testing with a slit impactor can be used for checking on the collection of plutonium aerosols, while various other instruments with a mobile filter were tested with beta-emitting aerosols. The testing device can also be used for studying the distribution of aerosols on fixed filters and for investigating deposits in pipelines and sampling containers. (author)

  5. Development of a semi-automatic segmentation method for retinal OCT images tested in patients with diabetic macular edema.

    Directory of Open Access Journals (Sweden)

    Yijun Huang

    Full Text Available PURPOSE: To develop EdgeSelect, a semi-automatic method for the segmentation of retinal layers in spectral domain optical coherence tomography images, and to compare the segmentation results with a manual method. METHODS: SD-OCT (Heidelberg Spectralis scans of 28 eyes (24 patients with diabetic macular edema and 4 normal subjects were imported into a customized MATLAB application, and were manually segmented by three graders at the layers corresponding to the inner limiting membrane (ILM, the inner segment/ellipsoid interface (ISe, the retinal/retinal pigment epithelium interface (RPE, and the Bruch's membrane (BM. The scans were then segmented independently by the same graders using EdgeSelect, a semi-automated method allowing the graders to guide/correct the layer segmentation interactively. The inter-grader reproducibility and agreement in locating the layer positions between the manual and EdgeSelect methods were assessed and compared using the Wilcoxon signed rank test. RESULTS: The inter-grader reproducibility using the EdgeSelect method for retinal layers varied from 0.15 to 1.21 µm, smaller than those using the manual method (3.36-6.43 µm. The Wilcoxon test indicated the EdgeSelect method had significantly better reproducibility than the manual method. The agreement between the manual and EdgeSelect methods in locating retinal layers ranged from 0.08 to 1.32 µm. There were small differences between the two methods in locating the ILM (p = 0.012 and BM layers (p<0.001, but these were statistically indistinguishable in locating the ISe (p = 0.896 and RPE layers (p = 0.771. CONCLUSIONS: The EdgeSelect method resulted in better reproducibility and good agreement with a manual method in a set of eyes of normal subjects and with retinal disease, suggesting that this approach is feasible for OCT image analysis in clinical trials.

  10. An evaluation of loop current step response time testing equipment for thermocouples

    International Nuclear Information System (INIS)

    In process instrumentation systems of such as nuclear plants, response time information is very important in most temperature transient measurements. Generally the response time of thermocouples is measured at a laboratory by using a plunge method. However, it is not easy to use the plunge testing method when a response time measurement of an installed thermocouple is required. A measurement system was developed to measure the response time of a thermocouple installed in a process by using the Loop Current Step Response(LCSR) testing method. This device heats a thermocouple by providing an electrical current, and then it measures the thermocouple output as the temperature of the thermocouple measurement junction returns to ambient temperature. The time constant of the thermocouple is determined from the transient curve of the thermocouple output indicating the temperature difference between the reference junction and measurement junction of the thermocouple. The device is designed to heat a middle point to reduce the temperature error caused by residual heat of thermocouple wire

  11. Design of an equipment for the testing of target dedicated to the production of radioactive ions through the ISOL method

    International Nuclear Information System (INIS)

    In the ISOL (isotope separation on line) technique, a primary ion beam impinges on a thick target, the incident ions are stopped through fragmentation reactions that generate radioactive nuclei. As soon as they have collected enough electrons, the radioactive nuclei begin diffusing outside the target as radioactive atoms. In order to improve this diffusion the target is strongly heated. The radioactive atoms diffuse till a ion source that ionize them, they are then accelerated to form a secondary beam that is delivered to the experimental area. This work deals with the design of an equipment able to measure the diffusion capacities of various targets, it is made up of -) a high temperature (> 2300 K) oven that will contain the target, -) a ionization source for ionizing radioactive atoms and -) a target dispatcher able to introduce in the oven or remove from the oven any target of a set of 12 targets. This equipment has proved to be able to test during a single experiment several primary beams and target materials. Measurements will be performed in a sequential way for the different projectile-target couples which will assure very closed experimental conditions for each measuring campaign. (A.C.)

    Froth flotation technique is an effective and efficient process for recovering of ultra-fine (minus 74 {mu}m) clean coal. Economical dewatering of an ultra-fine clean coal product to a 20 percent level moisture will be an important step in successful implementation of the advanced cleaning processes. This project is a step in the Department of Energy`s program to show that ultra-clean coal could be effectively dewatered to 20 percent or lower moisture using either conventional or advanced dewatering techniques. As the contract title suggests, the main focus of the program is on proof-of-concept testing of a dewatering technique for a fine clean coal product. The coal industry is reluctant to use the advanced fine coal recovery technology due to the non-availability of an economical dewatering process. in fact, in a recent survey conducted by U.S. DOE and Battelle, dewatering of fine clean coal was identified as the number one priority for the coal industry. This project will attempt to demonstrate an efficient and economic fine clean coal slurry dewatering process.

    The Brazilian Sanitary Agency from Ministry of Health requires that all PET/CT equipment must undergo minimal quality control tests using manufacturer simulators. The PET-NEMA/IEC body phantom is recommended by the IEC and NEMA to perform acceptance testing and quality control in PET/CT equipment according to specific protocols. It is essential that all simulator components (spheres and body) are properly characterized in relation to their size and internal structure volumes, since they are used to calculate the overall activity concentration and the total weight. The objective of this work was characterize a PET-NEMA/IEC body phantom for the true reconstruction in computational modeling and correct analysis of experimental results. The simulator is basically composed of three structures: the body (simulating a portion of the chest), an inner cylinder (simulating the lung tissue) and a top cover in which are coupled spheres of different sizes simulating 'hot' (tumors) and cold lesions. The spheres were evaluated in terms of volume. The same evaluations were performed with the body of the simulator and the inner cylinder, beyond of analysis of their weights (filled with water) and wall thickness. The data showed that the total weight of the simulator with all its internal structures is 12.5 kg and the volume of the 'hot' and 'cold' spheres are approximately equal to those presented by the manufacturer. The inner cylinder volume showed a significant difference between the measured and the presented in the manual. The results were used for reconstruction of the simulator in computational modeling using the code GATE. (author)

  17. a New Design for Diamond Window Equipped Paris-Edinburgh — First Tests and Results

    High pressure cells of the Paris-Edinburgh type are important tools for experimental high pressure studies in material science. Although these cells were originally developed for use in neutron diffraction, today they are also applied in alternative experimental high pressure fields. Their main advantages are their small construction size, limited weight and the relative high reachable pressures with a maximized sample volume. The small construction size also results in very good cost efficiency. The major drawback of these cells is that due to their simple squeezer geometry pressure extrapolations are nearly impossible and, hence, the use of internal standard is mandatory. Consequently, the normal use of Paris-Edinburgh cells is mostly limited to experiments with neutron or synchrotron radiation, during which pressure and temperature are determined by using an internal diffraction standard. To overcome this problem, tone may combine the advantages of diamond anvil cells with those of Paris-Edinburgh-cells by integrating diamond windows into the upper and / or the lower anvil. With such a cell it is possible to retrieve pressure and / or temperature data by measuring the shift of Raman bands or fluorescence lines by spectroscopic methods. Several attempts have been made to build such a cell ([1] and Klotz pers. communication) using different window materials. Until now no final setup has been published. We present a new Paris-Edinburgh cell design especially constructed for use within high energy relativistic heavy ion radiation experiments. This design uses conventional diamond anvils as spectroscopic windows in conjunction with specially designed hardened steel anvils. We have performed first feasibility studies up to 2.5 GPa with a standard Raman spectrometer using a special adapted Raman glass fiber probe. We present results of several mechanical test runs and one experiment with relativistic heavy ion radiation at the GSI Helmholtzzentrum f

    Powder flow in small-scale equipment is challenging to predict. To meet this need, the impact of consolidation during powder flow characterization, the level of consolidation existing during discharge of powders from a tablet press hopper and the uncertainty of shear and wall friction measurements at small consolidation stresses were investigated. For this purpose, three grades of microcrystalline cellulose were used. Results showed that powder flow properties depend strongly on the consolidation during testing. The consolidation during discharge in terms of the major principal stress and wall normal stress were approximately 200 Pa and 114 Pa, respectively, in the critical transition from the converging to the lower vertical section of the hopper. The lower limit of consolidation for the shear and wall friction test was approximately 500 Pa and 200 Pa, respectively. At this consolidation level, the wall and shear stress resolution influences the precision of the measured powder flow properties. This study highlights the need for an improved experimental setup which would be capable of measuring the flow properties of powders under very small consolidation stresses with a high shear stress resolution. This will allow the accuracy, precision and applicability of the shear test to be improved for pharmaceutical applications. PMID:25178826

  20. Irradiation and testing of off-the-shelf seal materials for water hydraulic applications in ITER remote handling equipment

    International Nuclear Information System (INIS)

    Remote handling (RH) is one of the most challenging aspects of the ITER project, and the European home team is building a major prototype of the divertor region (the Divertor Test Platform 2) to confirm practically the RH concepts proposed in this area. To handle the 9 Tonne divertor cassette, water hydraulics has been selected because it offers high forces and precise control in a compact envelope, with minimal long-term contamination should a leak develop. Water hydraulic components use mainly stainless steel - unaffected by gamma radiation - but the integral seals and O-rings are known to be sensitive. For radiation testing of these components, a modular approach was adopted, enabling up to 11 seal carriers assemblies to be irradiated simultaneously in the limited space available, with individual carriers being removed at varying total doses up to 10 MGy. Each carrier was then installed in a real hydraulic rig for testing, revealing not only at what total dose the components became unusable, but also how they fail, enabling condition monitoring to assess the state of the seals long before their failure might render the RH equipment irrecoverable

    This is the report on the third part of a development started 1998 at the Swiss Federal Institute of Technology Lausanne (EPFL) in Lausanne, Switzerland. Energy piles are becoming increasingly used as a heat exchanger and heat storage device, as are geothermal probes. Their design and sizing is subject to some uncertainty due to the fact that the planner has to estimate the thermal and mechanical properties of the ground surrounding the piles or probes. The aim of the project was to develop an apparatus for field measurements of thermal and mechanical properties of an energy pile or a geothermal probe (thermal response tests). In the reported third phase of the project the portable apparatus was equipped with a data transmission device using the Internet. Real-time data acquisition and supervision is now implemented and data processing has been improved. Another goal of the project was to obtain the official accreditation of such response tests according to the European standard EN 45,000. First operation experience from a test in Lyon, France is reported.

  4. Ion chamber-electrometer measurement system for radiation protection tests in X-ray equipment for interventional procedures

    International Nuclear Information System (INIS)

    A new parallel plate ionization chamber with volume of 500 cc and an electrometer with digital interface for data acquisition, configuring an ion chamber electrometer measurement system, were developed to comply with specific requirements for compulsory radiation protection tests in interventional X-ray equipment. The ion chamber has as main characteristics: low cost, mechanical strength and response variation with beam energy of less than 5% in the 40 kV to 150 kV range. The electrometer has a high gain (5x108 V/A) transimpedance amplifier circuit and a data acquisition and control system developed in LabVIEW ® platform, including an integrated power supply for the ion chamber bias with adjustable DC voltage output from O to 1000 V and an air density correction system. Electric field calculations, laboratory measurements in standard beams and computational simulations of radiation interactions in chamber volume with Monte Carlo Method were employed in the elaborated methodology of the ion chamber development, which was tested and validated. It was also developed a simplified methodology for electrometer calibration that assures metrological trustworthiness of the measurement system. Tests for the system performance evaluation as environmental influence response, energy response, angular dependency, linearity and air kerma and air kerma rate dependency were performed according to international standards and requirements. Additionally, for a detailed evaluation of the developed ion chamber, simulations with various scattered radiation spectra were performed. The system was applied in leakage radiation, residual radiation and scattered radiation tests, being compared with other reference systems and validated for laboratorial test routine. (author)

  6. Irradiation and Testing of off-the-shelf Seal Materials for Water Hydraulic Applications in ITER Remote Handling Equipment

    International Nuclear Information System (INIS)

    Remote Handling (RH) is one of the most challenging aspects of the ITER project, and the European home team is presently designing and constructing a major prototype of the divertor region (the Divertor Test Platform 2) to confirm practically the concepts proposed for the RH systems in this area. The divertor handling equipment must lift and transport the 9 Tonne divertor cassette around the vessel and down the narrow duct from the vessel to a sealed cask which will take the cassette to the hot cell. Due to limited access, the cassette must be grappled in a cantilevered manner, and water hydraulics has been selected because the required high forces and precise control are available in a compact envelope, with minimal long-term contamination of the vessel or duct should a leak develop. Although the main material used in water hydraulic components is stainless steel (unaffected by secondary gamma radiation), the seals and O-rings inside these components are more sensitive. With promising materials identified in earlier tests, a number of identical seal-carrier assemblies were manufactured upon which standard seals and O-rings were fitted and subjected to increasing doses of irradiation representative of those predicted in the radial duct region. Since the seal carriers are annular, space is also available for material samples for complementary mechanical testing. After irradiation, the carriers can then be assembled onto a specially modified piston and cylinder where various key parameters, like friction and leakage can be derived and compared with the same tests carried out on the pre-irradiated assemblies. This modular approach minimises the space required for irradiation (a chamber 60 mm diameter x 100 mm long can hold 10 seal assemblies), enables the effects of progressive radiation to be studied, and can allow several materials to be tested under realistic hydraulic conditions in a short time. Initial tests used UHMW-PE material for the seals, and NBR for the O

    Tuberculosis infection is prevalent in Korea and health care workers are vulnerable to tuberculosis infection in the hospital. The aims of this study were to develop and validate an education program that teaches senior medical students how to wear and choose the proper size and type of respiratory protective equipment (RPE), which may help reduce the risk of contracting Mycobacterium tuberculosis (MTB) from patients. Overall, 50 senior medical students participated in this education program. Methods of choosing the proper type of RPE, performing a fit check of the RPE, and choosing a suitable mask size were taught by certified instructors using the real-time quantitative fit test (QNFT). The validity of education program was evaluated with qualitative fit test (QLFT) before and after the education as pass or fail. The education program was effective, as shown by the significantly pass rate (increased 30 to 74%) in the QLFT after the education program (p<0.05). Among study participants, changing mask size from medium to small significantly increased the pass rate (p<0.001). Incorporation of this program into the medical school curriculum may help reduce risk of MTB infection in medical students working in the hospital. PMID:26538001

    With the purpose of developing an electromagnetic tomography system, an observation was carried out with existing equipment combined, and the data was analyzed. The measuring equipment consisted of existing borehole vertical magnetic field sensors as the sensor part, MT method receivers as the receiving device, and existing CSMT method transmitters as the transmitting device. The measuring was performed at the Richmond Field Station which was abundant in existing data and which had a comparatively simple resistivity structure. The borehole vertical magnetic field sensors were lowered inside the borehole, and signal sources were arranged at 10m apart on the traverse line in the direction from northeast to southwest with the borehole as the center. The analysis of the data was made with the use of EM1D by three models, namely, 10 ohm{center_dot}m homogeneous earth model, 100 ohm{center_dot}m homogeneous earth model, and horizontal 7 layer model prepared on the basis of electric logging results; and a comparative examination was made against the measured data. As a result, it was demonstrated that the test measurement agreed very well with the model from the electric logging results and that it was the data reflecting a resistivity structure. 8 refs., 6 figs.

  15. Development of an electrolytic decontamination technique without connecting power supply to metal wastes. Dissolution test of metals by engineering scale test equipment

    International Nuclear Information System (INIS)

    Ordinary monopolar electrolytic decontamination needs manual handling to connect an anode of the current power supply directly to the radioactive metallic wastes. The procedure results in radiation exposure for operators. The purpose of this study is to develop a bipolar electrolytic decontamination method in which no connection of the current power supply to the radioactive metallic wastes is needed. Engineering scale decontamination equipment was assembled to validate the method using up to 500 mm long samples. Test results showed that the piping was dissolved more effectively than plane samples because of lower leak current. Moreover, dissolution fluctuation is almost homogeneous (in the standard deviation of less than 10%) for plate and pipe sample. The fluctuation was larger at the bending plate sample. It was also evaluated that the samples could be decontaminated remotely even in a basket and that safety assurance and radiation exposure reductions due to the remote handling were feasible.

  16. SRV-automatic handling device

    International Nuclear Information System (INIS)

    Automatic handling device for the steam relief valves (SRV's) is developed in order to achieve a decrease in exposure of workers, increase in availability factor, improvement in reliability, improvement in safety of operation, and labor saving. A survey is made during a periodical inspection to examine the actual SVR handling operation. An SRV automatic handling device consists of four components: conveyor, armed conveyor, lifting machine, and control/monitoring system. The conveyor is so designed that the existing I-rail installed in the containment vessel can be used without any modification. This is employed for conveying an SRV along the rail. The armed conveyor, designed for a box rail, is used for an SRV installed away from the rail. By using the lifting machine, an SRV installed away from the I-rail is brought to a spot just below the rail so that the SRV can be transferred by the conveyor. The control/monitoring system consists of a control computer, operation panel, TV monitor and annunciator. The SRV handling device is operated by remote control from a control room. A trial equipment is constructed and performance/function testing is carried out using actual SRV's. As a result, is it shown that the SRV handling device requires only two operators to serve satisfactorily. The required time for removal and replacement of one SRV is about 10 minutes. (Nogami, K.)

  3. Nondestructive testing of weldings

    International Nuclear Information System (INIS)

    Today the nondestructive testing of materials with transverse weldings would be often neglect. Because the production of this parts will get more expensive it is interesting to test the parts eg. cans with ultrasound. Within this research program we developed a testing device for automatically testing of materials with transverse weldings, e.g. tubes. Functional characteristics: after putting in the test tube in the testing device the transducer is adjusted automatically to the best adjustment. This takes place with three step motors. The mechanic of adjustments gets its information from an optimal computer. The optimal computer processes the signals, which it gets from the automatic evaluator during the adjustment and stores the optimal adjustment parameters. With an additional equipment on can identify the exact source of error, if the testing device turns out and the repairing of the part can take place very fast. With an appropiate mechanical science the devide is useable in a production line with high flow rate. (orig.)

    1988-01-01

    Automatic Detection of Electric Power Troubles (A DEPT) is an expert system that integrates knowledge from three different suppliers to offer an advanced fault-detection system. It is designed for two modes of operation: real time fault isolation and simulated modeling. Real time fault isolation of components is accomplished on a power system breadboard through the Fault Isolation Expert System (FIES II) interface with a rule system developed in-house. Faults are quickly detected and displayed and the rules and chain of reasoning optionally provided on a laser printer. This system consists of a simulated space station power module using direct-current power supplies for solar arrays on three power buses. For tests of the system's ablilty to locate faults inserted via switches, loads are configured by an INTEL microcomputer and the Symbolics artificial intelligence development system. As these loads are resistive in nature, Ohm's Law is used as the basis for rules by which faults are located. The three-bus system can correct faults automatically where there is a surplus of power available on any of the three buses. Techniques developed and used can be applied readily to other control systems requiring rapid intelligent decisions. Simulated modeling, used for theoretical studies, is implemented using a modified version of Kennedy Space Center's KATE (Knowledge-Based Automatic Test Equipment), FIES II windowing, and an ADEPT knowledge base.

  11. IEEE Std 99-1980: IEEE recommended practice for the preparation of test procedures for the thermal evaluation of insulation systems for electric equipment

    International Nuclear Information System (INIS)

    The purpose of this recommended practice is to provide a general form for the preparation of test procedures and to suggest the points to be considered by technical committees in the preparation of specific instructions for the thermal evaluation of insulation systems for equipment. The thermal evaluation of an insulation system involves the thermal (T) factor of influence as described in IEC 505 (1975), Guide for the Evaluation and Identification of Insulation Systems of Electric Equipment. These test procedures involve accelerated thermal aging of insulation systems and specify tests which the committees deem pertinent, based on conditions of use. The objective of these test procedures is to provide for the functional evaluation, by test, of insulation systems for electric equipment. The evaluation of insulating materials and simple combinations thereof is provided for by a separate material test guide, IEEE Std 98-1972, Guide for the Preparation of Test Procedures for the Thermal Evaluation and Establishment of Temperature Indexes of Solid Electrical Insulating Materials

  12. Results of an automatic evaluation of test images according to PAS 1054 and IEC 6220-1-2 on different types of digital mammographic units

    International Nuclear Information System (INIS)

    Aim: to test whether image processing methods are suitable for detecting differences in the image quality of digital mammography units and whether the methods are more sensitive than visual test methods like the evaluation of CDMAM test images. Methods: test images according to PAS 1054 were acquired with CR and DR systems and analyzed automatically. Only parameters were used that are obligatory for calculating the detective quantum efficiency (DQE), the noise power spectrum (NPS), the spatial resolution (MTF, modulation transfer function), and the averaged glandular dose (AGD). The derived value, the NEQ index, is linked to the noise equivalent quanta (NEQ). Additionally CDMAM test images were acquired and evaluated at one CR and one DR system. Results:0e accuracy of the evaluated values is in the range below of 2%. The accuracy requirements are fulfilled to establish values for detecting changes in image quality related to changes in dose no greater than one exposure value. If a visual evaluation of test images is used, a significant difference in image quality can only be detected when the dose is doubled. Conclusion: a method is proposed for establishing dose-correlated tolerances for values used in constancy and acceptance tests independently of the type of mammography unit (CR and DR systems). A method which abstains from visual tests for establishing the performance of digital mammography units could be used in acceptance tests. (orig.)

  16. Nondestructive testing of materials

    International Nuclear Information System (INIS)

    NUKEM has transferred know-how from reactor technology to materials testing. The high and to a large extent new quality standards in the nuclear industry necessitate reliable measuring and testing equipment of the highest precision. Many of the tasks presented to us could not be solved with the equipment available on the market, for which reason we have developed our own measuring, testing and control systems. We have therefore acquired considerable experience in dealing with specific measuring, testing and control tasks and can handle even out-of-the-way problems that are submitted to us from a wide variety of fields. Our mechanical systems for the checking of close-tolerance gaps, the automatic determination of pellet dimensions and the measurement of absolute lengths and absolute velocities are in use in many different industrial fields. We have succeeded in solving unusual testing and sorting problems with the aid of automated surface testing equipment working on optical principles. Our main activities in the field of non-destructive testing have been concentrated on ultrasonic and eddy current testing and, of late, acoustic emission analysis. NUKEM ultrasonic systems are notable for their high defect detection rate and testing accuracy, combined with high testing speed. The equipment we supply includes ultrasonic rotary systems for the production testing of quality tubes, ultrasonic immersion systems for the final testing of reactor cladding tubes, weld testing equipment, and test equipment for the bonds in multi-layer plates.

    Most research on test case generation from Object-Z specification focuses on theory. There is almost no tool to support generating test cases automatically. The Object-Z is a mathematics and logic based formal specification language. It uses schema composition and abbreviation format, which brings difficulty for extracting semantics and then generating test cases from specification automatically. This paper provides a solution in extracting semantics and generating test cases from Object-Z specification by unfolding the schema definition and improving its syntax in Object-Z. The process has three steps including parsing Object-Z language, extracting semantics, and generating test cases automatically.%对Object-Z形式规格说明构造测试用例的研究,目前主要集中在理论研究阶段,测试用例的自动生成几乎没有相应的工具支持.Object-Z是基于数学和逻辑的语言,并大量使用了模式复合和简写形式,这给计算机提取完整语义用以自动产生测试用例造成了困难.通过展开Object-Z规格说明中的模式定义,改进Object-Z的文法结构,给出了提取Object-Z规格说明语义的方法,研究了从Object-Z规格说明产生测试用例的自动化过程.这一过程主要包含3个阶段:Object-Z语言的自动解析、语义自动抽取和测试用例自动产生.通过介绍的工具原型,可以很容易得到规格说明中的各种语义;基于某些测试准则,能够方便自动产生可视化的抽象测试用例.

    1987-02-01

    The DGMP-working group has established a test program by which it is possible to perform uniformly the performance test mentioned in DIN 6868, part 1 at fluoroscopic X-ray devices. The program has the following fundamental aims: 1) Uniformity of the testing extent, measuring conditions and test criteria. 2) Simple procedure of testing. 3) Definition of a reference dose rate ('transmission dose rate') by which the radiation exposure of the patient due to the given technical conditions can be characterized. 4) Definition of comparability criteria for dose rate measurements at fluoroscopic X-ray devices with different kinds of automatic dose rate control (mean value or maximum value). The conditions for the applicable measuring phantom and the measuring arrangement are deduced from these criteria. A model test program is presented for the most important single steps of a performance test. The practical trial of the test methods has revealed the possibility to get an evidental performance test in a fast and simple way by using suitable measuring devices.

  4. Quality assurance applied to mammographic equipments using phantoms and software for its evaluation

    International Nuclear Information System (INIS)

    The image quality assessment in radiographic equipments is a very important item for a complete quality control of the radiographic image chain. The periodic evaluation of the radiographic image quality must guarantee the constancy of this quality to carry out a suitable diagnosis. Mammographic phantom images are usually used to study the quality of images obtained by determined mammographic equipment. The digital image treatment techniques allow to carry out an automatic analysis of the phantom image. In this work we apply some techniques of digital image processing to analyze in an automatic way the image quality of mammographic phantoms, namely CIRS SP01 and RACON for different varying conditions of the mammographic equipment. The CIRS SP01 phantom is usually used in analogic mammographic equipments and the RACON phantom has been specifically developed by authors to be applied to acceptance and constancy tests of the image quality in digital radiographic equipments following recommendations of international associations. The purpose of this work consists in analyzing the image quality for both phantoms by means of an automatic software utility. This analysis allows us to study the functioning of the image chain of the mammographic system in an objective way, so an abnormal functioning of the radiographic equipment might be detected.

  6. Application of PSA methodology for optimization of repairs, maintenance and tests modes of the equipment of NPPs with RBMK types reactors

    International Nuclear Information System (INIS)

    The present paper is an example of the use of PSA (Probabilistic Safety Assessment) level 1, as a tool for risk monitoring at planning of repairs, maintenance and tests of technical systems equipment of Leningrad Power Plant Unit 1. PSA methodology allows us to determine the importance of Allowable Outage Time (AOT) of equipment and periodic checks intervals, to calculate limiting values of these parameters and, if necessary, to make its optimization. Regulations of NPPs operation defines AOT as follows: AOT is the time, when equipment or a technical system is out of service for repair, maintenance and tests. For determination of the importance of failures (here removing out of service) of system components or a system it is necessary to estimate Risk Increase Factor (RIF) for each basic event (i) in PSA method, level 1: RIF equals CDF(i)/CDF(ib), where CDF(i) is the Core Damage Frequency when the failure probability for given (i) basic event is equal to 1, CDF(ib) is the analogues real (basic-b) value for the given (i) basic event. Knowing the RIF value it is possible to determine importance of a component or a system, which is removing out of service, and to optimize items of Regulations, relating to AOT values. This methodology has been applied to the optimization of Allowable Outage Times for Leningrad power plant equipment, which is removed out of service for repair, maintenance and tests. It was showed that there are 2 dangerous modes of operation: the simultaneous removing for repair of two pumps (Accident Feed Water Pumps) 1APN-4 and 1APN-5, and the removing for repair of the ECCS tank

    2014-10-01

    Volume 2: Improved Sensor and Control Designs Many residential clothes dryers on the market today provide automatic cycles that are intended to stop when the clothes are dry, as determined by the final remaining moisture content (RMC). However, testing of automatic termination cycles has shown that many dryers are susceptible to over-drying of loads, leading to excess energy consumption. In particular, tests performed using the DOE Test Procedure in Appendix D2 of 10 CFR 430 subpart B have shown that as much as 62% of the energy used in a cycle may be from over-drying. Volume 1 of this report shows an average of 20% excess energy from over-drying when running automatic cycles with various load compositions and dryer settings. Consequently, improving automatic termination sensors and algorithms has the potential for substantial energy savings in the U.S.

    In the present research, blending of polymers used in electrical and electronic equipment, i.e. acrylonitrile-butadiene-styrene terpolymer, polycarbonate and polypropylene, was performed in a twin-screw extruder, in order to explore the effect process parameters on the mixture properties, in an attempt to determine some characteristics of a fast and economical procedure for waste management. The addition of polycarbonate in acrylonitrile-butadiene-styrene terpolymer seemed to increase its thermal stability. Also, the addition of polypropylene in acrylonitrile-butadiene-styrene terpolymer facilitates its melt processing, whereas the addition of acrylonitrile-butadiene-styrene terpolymer in polypropylene improves its mechanical performance. Moreover, the upgrading of the above blends by incorporating 2 phr organically modified montmorillonite was investigated. The prepared nanocomposites exhibit greater tensile strength, elastic modulus and storage modulus, as well as higher melt viscosity, compared with the unreinforced blends. The incorporation of montmorillonite nanoplatelets in polycarbonate-rich acrylonitrile-butadiene-styrene terpolymer/polycarbonate blends turns the thermal degradation mechanism into a two-stage process. Alternatively to mechanical recycling, the energy recovery from the combustion of acrylonitrile-butadiene-styrene terpolymer/polycarbonate and acrylonitrile-butadiene-styrene terpolymer/polypropylene blends was recorded by measuring the gross calorific value. Comparing the investigated polymers, polypropylene presents the higher gross calorific value, followed by acrylonitrile-butadiene-styrene terpolymer and then polycarbonate. The above study allows a rough comparative evaluation of various methodologies for treating plastics from waste from electrical and electronic equipment. PMID:25750055

    an HSV color space for image filtering, then used median filtering and morphological filtering for the image to reduce white noise, eliminating holes in the target area to improve the image quality, and then divided the image into blocks based on the adjacent pixels of the image and used these blocks for Geometric feature matching, so that the bactrocera dorsalis area could be extracted. Finally, this paper used the watershed algorithm based on weight for an image segment to get the tracking object and tag the object. For bactrocera dorsalis tracking, this paper used a Kalman filter to predict the target movement position, narrowing the range of target searching and target matching, reducing the amount of calculation of the target matching;and established a cost model by using centroid Euclidean distance, survival time, and the color difference of the target between two consecutive frames;updated the cost model of each tracked target, and handled the missing target to ensure the stability and accuracy of the tracking algorithm. For bactrocera dorsalis metering, this paper studied a counting strategy for moving targets. This equipment was tested in the laboratory environment. There were 138 bactrocera dorsalis entered in the equipment in 830 s, the detected result of the system was 131, and the detection success rate was 94.9%. Also this equipment was tested in the Yangtao Park for more than a year (from November 2013 to December 2014), and the system hardware and software could work cooperatively and stably. The system stopped running only when there was a shortage of solar power, rendering it ineffective under grim weather for lack of the light. The IOT-Based remote monitoring equipment for bactrocera dorsalis trapping could automatically track and count the number of bactrocera dorsalis. It could also provide simple and effective monitoring information to the regional monitoring personnel, improve work efficiency, greatly improve the performance of the monitoring

    We investigate the application of the discontinuous Petrov-Galerkin (DPG) finite element framework to stationary convection-diffusion problems. In particular, we demonstrate how the quasi-optimal test space norm improves the robustness of the DPG method with respect to vanishing diffusion. We numerically compare coarse-mesh accuracy of the approximation when using the quasi-optimal norm, the standard norm, and the weighted norm. Our results show that the quasi-optimal norm leads to more accurate results on three benchmark problems in two spatial dimensions. We address the problems associated to the resolution of the optimal test functions with respect to the quasi-optimal norm by studying their convergence numerically. In order to facilitate understanding of the method, we also include a detailed explanation of the methodology from the algorithmic point of view. © 2013 Elsevier Ltd. All rights reserved.

    This paper introduces research done on the automatic preparation of remediation plans and navigation data for the precise guidance of heavy machinery in clean-up work after an industrial disaster. The input test data consists of a pollution extent shapefile derived from the processing of hyperspectral aerial survey data from the Kolontár red mud disaster. Three algorithms were developed and the respective scripts were written in Python. The first model aims at drawing a parcel clean-up plan. The model tests four different parcel orientations (0, 90, 45 and 135 degree) and keeps the plan where clean-up parcels are less numerous considering it is an optimal spatial configuration. The second model drifts the clean-up parcel of a work plan both vertically and horizontally following a grid pattern with sampling distance of a fifth of a parcel width and keep the most optimal drifted version; here also with the belief to reduce the final number of parcel features. The last model aims at drawing a navigation line in the middle of each clean-up parcel. The models work efficiently and achieve automatic optimized plan generation (parcels and navigation lines). Applying the first model we demonstrated that depending on the size and geometry of the features of the contaminated area layer, the number of clean-up parcels generated by the model varies in a range of 4% to 38% from plan to plan. Such a significant variation with the resulting feature numbers shows that the optimal orientation identification can result in saving work, time and money in remediation. The various tests demonstrated that the model gains efficiency when 1/ the individual features of contaminated area present a significant orientation with their geometry (features are long), 2/ the size of pollution extent features becomes closer to the size of the parcels (scale effect). The second model shows only 1% difference with the variation of feature number; so this last is less interesting for planning

    In order to solve the feeding problem in river crab aquaculture such as high labor intensity, low automation and non-uniform feed distribution, an automatic air propeller driven feeding system carried by a workboat and uniform feeding method was proposed. The system is mainly composed of a workboat driven by air propellers, automatic feeding device, ARM (advanced RISC machine) main controller, GPRS (general packet radio service) communication module and GPS (global positioning system) navigation device. A air propeller driven device was designed to solve the effect of waterweeds intertwine with underwater propellers of common workboat on sailing, and an automatic feeding device equipped with the flow velocity controllable bait feeder, distance adjustable thrower and quantity of feed in the bin measurable device was designed to solve the problem of non-uniform distribution of the feed. The ARM S3C2440 was used for the control system which could perform automatic uniform feeding by receiving task information through the GPRS communication module M590, modeling for the thrower of the automatic feeding device, motion of the feed particle and cumulative distribution of feed on the water, creating a target function for cumulative distribution density, using genetic algorithm (GA) to solve the optimal operation parameters such as flow velocity of the feeder, speed of the rotary table, feed sector angle, speed of the workboat and distance between adjacent feeding travel of trajectory planning which optimal value of distance between adjacent feeding travel was 8.21 m, feed sector angle was 80°, the workboat speed above and below the feeding travel were both 0.43 m/s, flow velocity of the feeder was 32.01 g/s, speed of the rotary table was 1480 r/min when the expected value of distribution density was 9 g/m2, and implementing trajectory tracking by GPS navigation device BD982.

    Manual in-situ measurements of geometric tree parameters for the biomass volume estimation are time-consuming and economically non-effective. Photogrammetric techniques can be deployed in order to automate the measurement procedure. The purpose of the presented work is an automatic tree growth estimation based on Unmanned Aircraft Vehicle (UAV) imagery. The experiment was conducted in an agriculture test field with scots pine canopies. The data was collected using a Leica Aibotix X6V2 platform equipped with a Nikon D800 camera. Reference geometric parameters of selected sample plants were measured manually each week. In situ measurements were correlated with the UAV data acquisition. The correlation aimed at the investigation of optimal conditions for a flight and parameter settings for image acquisition. The collected images are processed in a state of the art tool resulting in a generation of dense 3D point clouds. The algorithm is developed in order to estimate geometric tree parameters from 3D points. Stem positions and tree tops are identified automatically in a cross section, followed by the calculation of tree heights. The automatically derived height values are compared to the reference measurements performed manually. The comparison allows for the evaluation of automatic growth estimation process. The accuracy achieved using UAV photogrammetry for tree heights estimation is about 5cm.

    The main goal of the presented work was to evolve a multifunctional beam composed out of fiber reinforced plastics (FRP) and an embedded optical fiber with various fiber Bragg grating sensors (FBG). These beams are developed for the use as structural member for bridges or industrial applications. It is now possible to realize large scale cross sections, the embedding is part of a fully automated process and jumpers can be omitted in order to not negatively influence the laminate. The development includes the smart placement and layout of the optical fibers in the cross section, reliable strain transfer, and finally the coupling of the embedded fibers after production. Micromechanical tests and analysis were carried out to evaluate the performance of the sensor. The work was funded by the German ministry of economics and technology (funding scheme ZIM).

    The results of tests of plasma treatment of zirconium and deposition of protective yttrium coatings used as the methods of protection of zirconium components of light water reactor cores against hydrogenation are detailed. The amount of hydrogen in the treated sample exposed to superheated steam for 2500 h at temperature T = 400°C and pressure p = 1 atm was five times lower than the corresponding value for the untreated one. The amount of hydrogen in the sample coated with yttrium remained almost unchanged in 4000 h of exposure. A plasma method for rapid testing for hydrogen resistance is proposed. The hydrogenation rate provided by this method is 700 times higher than that in tests with superheated steam. The results of preliminary experiments confirm the possibility of constructing a unit for batch processing of the surfaces of fuel rod claddings.

    The continuous and reliable operation of nuclear power plants is critical to a utility's commercial bottom line. Many electric utilities with nuclear and other generating assets use non-nuclear generation to meet peak load and off-system power sales. Although motors installed during original construction have given fairly reliable service, the expectations in today's power generation market require that any improvements that could increase reliability should be used. This paper addressed the importance of reliability in a reactor coolant pump winding in a pressurized water reactor plant. The maintenance approach taken by one North American utility to avoid failure was presented. The challenges of the reactor coolant pump application was also discussed along with the improvements made in the winding design and construction. It was noted that the design margins incorporated into a reactor coolant pump motor will probably exceed those used for similar sized induction motors used for other industries due to the economic, radiological and nuclear safety concerns associated with an in service failure. As such, reactor coolant pump motors must meet special requirements based on the manufacturer experience, standards, electrotechnical standards and the customers request. The design of stators has resulted in improvements to address the following stress mechanisms: reduce thermal deterioration rate; inadequate resin bonding; loose windings; end winding corona; partial discharge; turn insulation stress or defects; and surface moisture and contamination. Validation testing was conducted on the replacement stator, including type tests on the initial stator and coils, in-process testing and final acceptance testing. All test results met the specified acceptance criteria. 7 refs., 2 tabs., 12 figs.

    Most of previous researches on solar air heating system (SAHS) were separated from real building. Actually, even though the building was equipped with a high-effective SAHS, the effective regulation could not be obtained without considering the building thermal responsive characteristics. In this paper,a test room equipped with wall-mounted solar air collector on south wall was taken as a research object,and in real coldest outdoor environment conditions (almost below -5 ℃ during night) ,dynamic variation process of indoor temperature under different conditions were experimentally studied based on the computer datalog system and outdoor weather station which could record data automatically. The experimental conditions included the different air supply modes, movable thermal insulation of window, direct-gain window's action and the factor of thermal mass materials. The results could provide the useful references for further studying the climate adaptation of this technology and predicting dynamic indoor temperature swings of building.%既有关于太阳能空气供暖系统(SAHS)的研究大多是脱离建筑物而进行的.然而,实际情况是,即便是配置一个高效的太阳能空气供暖系统,如果不考虑建筑物的热响应特性,往往也不能获得好的室内环境调节效果.本文以在南向墙设置有壁挂式太阳能空气集热器的实验房为研究对象,在实际最寒冷的室外气候条件下(夜间大多低于-5℃),利用计算机多点巡同检测系统和可自动记录数据的室外气象站,通过实测数据和理论分析研究了不同送风方式、窗户的移动式保温、直接受益窗单独作用及热质材料等因素作用下室内温度的动态变化过程,为今后进一步研究该项技术的地域适应性及预测建筑集成太阳能空气供暖系统作用下的动态室温波动提供了参考依据.

    Full Text Available VO2max is an excellent indicator of performance in endurance efforts such as rowing and evaluating it can be both a predictor of the level that could be reached in the competition and especially an effective benchmark in planning volume and intensity in the training process. The study aims to determine whether there are differences in VO2max values between the ergospirometry evaluation method using Cosmed Pro FitMate equipment in a specific ergometer test and VO2max evaluation using the Astrand-Ryhming test. Eight girls, rowers of the National Olympic Junior Training Center in Iasi, aged between 14 and 17 years, went through two tests to assess VO2max: the ergospirometry method using the Cosmed equipment FitMate Pro in a specific ergometer test and VO2max evaluation using the Astrand-Ryhming test. The recorded results indicate statistically significant differences between the two assessments (49,98 ml.kg-1.min-1 for the ergospirometry method and 40,39 ml.kg-1.min-1 in the Astrand-Ryhming test, p <0, 0001.

  2. The Effect of Specimen Size on the Results of Concrete Adiabatic Temperature Rise Test with Commercially Available Equipment

    2014-12-01

    Full Text Available In this study, adiabatic temperature rise tests depending on binder type and adiabatic specimen volume were performed, and the maximum adiabatic temperature rises and the reaction factors for each mix proportion were analyzed and suggested. The results indicated that the early strength low heat blended cement mixture had the lowest maximum adiabatic temperature rise (Q∞ and the ternary blended cement mixture had the lowest reaction factor (r. Also, Q and r varied depending on the adiabatic specimen volume even when the tests were conducted with a calorimeter, which satisfies the recommendations for adiabatic conditions. Test results show a correlation: the measurements from the 50 L specimens were consistently higher than those from the 6 L specimens. However, the Q∞ and r values of the 30 L specimen were similar to those of the 50 L specimen. Based on the above correlation, the adiabatic temperature rise of the 50 L specimen could be predicted using the results of the 6 L and 30 L specimens. Therefore, it is thought that this correlation can be used for on-site concrete quality control and basic research.

    2001-11-01

    Although most research on the control of automatic prejudice has focused on the efficacy of deliberate attempts to suppress or correct for stereotyping, the reported experiments tested the hypothesis that automatic racial prejudice is subject to common social influence. In experiments involving actual interethnic contact, both tacit and expressed social influence reduced the expression of automatic prejudice, as assessed by two different measures of automatic attitudes. Moreover, the automatic social tuning effect depended on participant ethnicity. European Americans (but not Asian Americans) exhibited less automatic prejudice in the presence of a Black experimenter than a White experimenter (Experiments 2 and 4), although both groups exhibited reduced automatic prejudice when instructed to avoid prejudice (Experiment 3). Results are consistent with shared reality theory, which postulates that social regulation is central to social cognition. PMID:11708561

    Actual regulatory conditions about ozone layer depleting chemicals set problems on their disposal and on the management of plants still using illegal CFCs. Anyway fluids that will replace CFCs (i.e. HFCs) will not be allowed to be spread into the atmosphere, due to their high costs and to the greenhouse effect. A viable solution would be the recovery, purification and recycle of contaminated fluids. ENEA (National Agency for New Technology, Energy and the Environment), in cooperation with ICF (Industria Componenti Frigoriferi) Company leader in the field of air refrigerating and conditioning, patented a device able to extract, to clean and to recycle CFC 12 and HFC 134a in the refrigerating systems. This paper presents experimental data from the qualification tests on a device performing the above mentioned operations regarding systems that use HFC 134a as process fluid.

    Energy storage systems are necessary for renewable energy sources such as solar power in order to stabilize their output power, which fluctuates widely depending on the weather. Since ‘flywheel energy storage systems’ (FWSSs) do not use chemical reactions, they do not deteriorate due to charge or discharge. This is an advantage of FWSSs in applications for renewable energy plants. A conventional FWSS has capacity limitation because of the mechanical bearings used to support the flywheel. Therefore, we have designed a superconducting magnetic bearing composed of a superconducting coil stator and a superconducting bulk rotor in order to solve this problem, and have experimentally manufactured a large scale FWSS with a capacity of 100 kWh and an output power of 300 kW. The superconducting magnetic bearing can levitate 4 tons and enables the flywheel to rotate smoothly. A performance confirmation test will be started soon. An overview of the superconducting FWSS is presented in this paper.

    Chars formed during air and oxygen blown gasification processes have a low reactivity. This is due to changes that occur in the structure and morphology of the original coal during heating. In part, the changes depend on conditions prevailing during the pyrolysis stage and partly on the length of time spent at peak temperature. Previous work in this laboratory has highlighted that the gasification reactivity of a char depends on the conditions of its formation. This means that chars must be prepared under realistic conditions when conducting laboratory scale reactivity studies that are intended to support a larger scale development. This is not easy to do and requires the development of dedicated methods for preparing the char. In this paper, the development of a laboratory-scale test, based on a laboratory-scale spouted bed gasifier, is described that is able to prepare chars under conditions that represent those in an air-blown gasifier. The reactivity of the prepared chars is then examined to identify how the reactivity of the char varies within the envisaged operating window of the process. A feature of this apparatus is that the char formation time is known accurately, which has required the development of novel feeding and draining mechanisms. These enable the coal particles to be injected quickly into the reactor and the sand/char bed drained and quenched rapidly after a known residence time. The extent of char deactivation can be measured with residence times between 2 and 3600 s. In this paper, the validation of the experiment is described and some preliminary results are reported. 7 refs., 10 figs., 2 tabs.

  14. Demonstration of the iodine and NO/sub x/ removal systems in the Oak Ridge National Laboratory integrated equipment test facility

    International Nuclear Information System (INIS)

    This report summarizes the findings from three sets of experiments on iodine and NO/sub x/ removal performance using dual downdraft condensers in the dissolver off-gas line. The initial experiments were conducted in the laboratory using glassware in proof-of-principle tests. Two additional sets of condenser experiments were conducted using equipment prototyical for a 0.5-t/d plant in the Integrated Equipment Test (IET) facility at the Oak Ridge National Laboratory. This report also describes the NO/sub x/ removal performance of a packed scrubber in the IET during the dissolution of depleted uranium oxides. The overall iodine pass-through efficiency of the condensers in the IET was high as desired. Removal efficiencies ranged from only 0.35 to 6.29%, indicating that the bulk of the iodine in the off-gas will be transferred on through the condensers to the iodox process for final disposal rather than recycled to the dissolver. The optimum operating temperature for the first condenser was in the range of 50 to 700C, with the temperature of the second condenser held near 200C. The NO/sub x/ removal performance of the combined dual condensers and packed scrubber resulted in effluent off-gas stream NO/sub x/ compositions of ∼0.4 to 1.0%, which are acceptable levels for the iodox process. The NO/sub x/ removal efficiency of the condensers ranged from ∼5 to 58%, but was generally around 20%. The removal efficiency of the packed tower scrubber was observed to be in the range of 40 to 60%. The NO/sub x/ removal performance of the condensers tended to complement the performance of the scrubber in that the condenser removal afficiency was high when the scrubber efficiency was low and vice versa

  16. Testing problems with regard to ultrasonic tube testing as well as principle and technical possibilities of solution by means of computer controlled test installations

    International Nuclear Information System (INIS)

    This concept for computer-controlled ultrasonic pipe testing devices is based on the experience gained with semi-automatic pipe testing devices. This new generation of test equipment requires adaptation with regard to oscilloscope patterns, analogue presentation, etc. This process of adaptation is necessary as only computer-controlled systems can solve the existing testing problems. The computer-controlled ultrasonic pipe testing system yields objective, reproducible, and valid results. (orig./RW)

    This work aims at presenting the ongoing research activities carried out in Working Group 1 'Novel GPR instrumentation' of the COST (European COoperation in Science and Technology) Action TU1208 'Civil Engineering Applications of Ground Penetrating Radar' (www.GPRadar.eu). The principal goal of the COST Action TU1208 is to exchange and increase scientific-technical knowledge and experience of GPR techniques in civil engineering, simultaneously promoting throughout Europe the effective use of this safe and non-destructive technique in the monitoring of infrastructures and structures. Working Group 1 (WG1) of the Action focuses on the development of innovative GPR equipment dedicated for civil engineering applications. It includes three Projects. Project 1.1 is focused on the 'Design, realisation and optimisation of innovative GPR equipment for the monitoring of critical transport infrastructures and buildings, and for the sensing of underground utilities and voids.' Project 1.2 is concerned with the 'Development and definition of advanced testing, calibration and stability procedures and protocols, for GPR equipment.' Project 1.3 deals with the 'Design, modelling and optimisation of GPR antennas.' During the first year of the Action, WG1 Members coordinated between themselves to address the state of the art and open problems in the scientific fields identified by the above-mentioned Projects [1, 2]. In carrying our this work, the WG1 strongly benefited from the participation of IDS Ingegneria dei Sistemi, one of the biggest GPR manufacturers, as well as from the contribution of external experts as David J. Daniels and Erica Utsi, sharing with the Action Members their wide experience on GPR technology and methodology (First General Meeting, July 2013). The synergy with WG2 and WG4 of the Action was useful for a deep understanding of the problems, merits and limits of available GPR equipment, as well as to discuss how to quantify the reliability of GPR results.

    This document was created to comply with the Central Valley Regional Water Quality Control Board (CVRWQCB) Waste Discharge Requirement (Order No. 98-148). This order established new requirements to assess the effect of and effort required to reduce salts in process water discharged to the subsurface. This includes the review of technical, operational, and management options available to reduce total dissolved solids (TDS) concentrations in cooling tower and mechanical equipment water discharges at Lawrence Livermore National Laboratory's (LLNL's) Experimental Test Site (Site 300) facility. It was observed that for the six cooling towers currently in operation, the total volume of groundwater used as make up water is about 27 gallons per minute and the discharge to the subsurface via percolation pits is 13 gallons per minute. The extracted groundwater has a TDS concentration of 700 mg/L. The cooling tower discharge concentrations range from 700 to 1,400 mg/L. There is also a small volume of mechanical equipment effluent being discharged to percolation pits, with a TDS range from 400 to 3,300 mg/L. The cooling towers and mechanical equipment are maintained and operated in a satisfactory manner. No major leaks were identified. Currently, there are no re-use options being employed. Several approaches known to reduce the blow down flow rate and/or TDS concentration being discharged to the percolation pits and septic systems were reviewed for technical feasibility and cost efficiency. These options range from efforts as simple as eliminating leaks to implementing advanced and innovative treatment methods. The various options considered, and their anticipated effect on water consumption, discharge volumes, and reduced concentrations are listed and compared in this report. Based on the assessment, it was recommended that there is enough variability in equipment usage, chemistry, flow rate, and discharge configurations that each discharge location at Site 300
