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

    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)

  2. Development of automatic Ultrasonic testing equipment for reactor pressure vessel

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


    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

    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

    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

    Spicer, John Patrick; Chakraborty, Debejyo; Wincek, Michael Anthony; Wang, Hui; Abell, Jeffrey A; Bracey, Jennifer; Cai, Wayne W


    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.

  20. Automatic Test Pattern Generation for Digital Circuits

    S. Hemalatha


    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.

In this study, we propose a general method for module automatic testing in the avionics test platform based on PXI bus. We apply virtual instrument technology to realize the automatic testing and the fault reporting of signal performance. Taking the avionics bus ARINC429 as an example, we introduce the architecture of automatic test system as well as the implementation of algorithms in Lab VIEW. The comprehensive experiments show the proposed method can effectively accomplish the automatic testing and fault reporting of signal performance. It greatly improves the generality and reliability of ATE in avionics systems.

  2. Development of remote automatic equipment for BWR power plants

    The development of remote control, automatic equipment for nuclear power stations has been promoted to raise the rate of operation of plants by shortening regular inspection period, to improve the safety and reliability of inspection and maintenance works by mechanization, to reduce the radiation exposure dose of workers and to reduce the manpower required for works. The taking-off of control rod drives from reactors and fixing again have been mechanized, but the disassembling, cleaning, inspection and assembling of control rod drives are manually carried out. Therefore, Hitachi Ltd. has exerted effort to develop the automatic equipment for this purpose. The target of development, investigation, the construction and function of the equipment, the performance and the effect of adopting it are reported. The equipment for the volume reduction of spent fuel channel boxes and spent control rods is developed since these are major high level radioactive solid wastes, and their apparent volume is large.

  3. Equipment fragility testing

    Current probabilistic risk assessment (PRA) methods for nuclear power plants utilize component fragilities which are for the most part based on a limited data base and engineering judgement. The seismic design of components is based on code limits and NRC requirements that do not reflect the actual capacity of a component to resist failure. In order to improve the present component fragility data base and establish component seismic design margins, the NRC has commissioned a projected three-year program to compile existing fragilities data and at the same time independently perform fragilities tests on selected mechanical and electrical components. This paper presents the planning and technical approach being taken by LLNL in the NRC Component Fragility Program

  8. Design of phantoms and software for automatic image analysis applied to digital radiographic equipments

    In a quality control of the radiographic equipment, the quality of the obtained image is very useful to characterize the physical properties of the image radiographic chain. In the radiographic technique it is necessary that the evaluation of the image can guarantee the constancy of its quality to carry out a suitable diagnosis. The use of digital systems allows the automatic analysis of the obtained radiographic images, increasing the objectivity in the evaluation of the image.

Moreover, the image quality analysis by the automatic software let study it with objective parameters and the functioning of the image chain of the digital system. (author)

  9. Fault injection system for automatic testing system

    王胜文; 洪炳熔


    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

    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)

  18. Understanding And Addressing Equipment Limitations Through Testing

    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

    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.

  3. Improvement of remote control system of automatic ultrasonic equipment for inspection of reactor pressure vessel

    One of the important issues related to the nuclear safety is in-service inspection of reactor pressure vessel (RPV). A remote controlled automatic ultrasonic method is applied to the inspection. At present the automatic ultrasonic inspection system owned by KAERI is interrupted due to degradation of parts. In order to resume field inspection new remote control system for the equipment was designed and installed to the existing equipment. New ultrasonic sensors and their modules for RPV inspection were designed and fabricated in accordance with the new requirements of the inspection codes. Ultrasonic sensors were verified for the use in the RPV inspection. (author)

  5. Equipment qualification testing - a practical approach

    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

    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

    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.

  10. Design and realization for automatic calibration of test equipment information exchange platform%自动化标定测试设备信息交互平台设计与实现

    万志江; 高辉文; 吴静


    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

    Upgrade Travel Funding' - This subtask provides funding for the upgrade of DIS equipment installed in the field; E.125.3, 'DIS Radiation Field Characterization' - This subtask provides for the procurement by the IAEA of radiation measurement equipment and technical assistance for the characterization of radiation conditions in the locations where DIS will be installed. 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

So generating adequate test cases will help to reduce the effort and cost of the software. The purpose of this research paper is to automatically generate test case...

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

    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.

  5. Focussed ultrasonic transducers for automatic testing of pressure apparatus operating

    In the framework of the French electronuclear program, the CEA developed an automatic method using focused ultrasonic transducers to inspect PWR vessels. Now, more than 60 examinations have been carried out by the CEA and Intercontrole (IC) with the robot called ''in-Service Inspection Machine'' (M.I.S) which as presented in this paper. Besides these examinations, IC uses focused ultrasonic transducers to test pressure apparatus according to regulations. So IC develops automatic devices. Through the experience acquired and with some examples, this paper presents the advantages of the constraints involved by this type of test

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

    E. Bean


    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

    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

  11. Challenges for High Voltage Testing of UHV Equipment

    Ernst Gockenbach


    The increase of voltage level for AC and DC transmission systems requires some changes in the high voltage testing for Ultra High Voltage (UHV) equipment. After a short description of the coordination work in the standard- ization bodies the requirements for UHV equipment are mentioned. The main points concerning high voltage testing of UHV equipment are the impulse shape of standard lightning impulse voltage, the evaluation of the test voltage for impulses with oscillations or overshoot near the peak and the time parameter of switching impulses. The linearity check of the measuring devices, the proximity effect, the wet tests and the atmospheric correction factors are further points to be discussed concerning testing of UHV equipment.

  12. Waste Handling Equipment Development Test and Evaluation Study

    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. Development test activities can be

  13. Experimental Applications of Automatic Test Markup Language (ATML)

    Lansdowne, Chatwin A.; McCartney, Patrick; Gorringe, Chris


    The authors describe challenging use-cases for Automatic Test Markup Language (ATML), and evaluate solutions. The first case uses ATML Test Results to deliver active features to support test procedure development and test flow, and bridging mixed software development environments. The second case examines adding attributes to Systems Modelling Language (SysML) to create a linkage for deriving information from a model to fill in an ATML document set. 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

    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

The efficiency of using the PG method in flight-navigation-equipment flight testing is shown.

  17. CFC and HFC recycling equipments: Test performances

    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

    Abbaszadeh, M.; Kamal, M.M.


    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

    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

  1. Testing of three-phase equipment under voltage sags

    Rolan Blanco, Alejandro; Córcoles, F.; Pedra, J.; Monjo, L.; Bogarra, S.


    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)...

  2. Initial acceptance test experience with FFTF plant equipment

    The purpose of this paper is to examine the initial acceptance test experience of certain pieces of auxiliary equipment of the Fast Flux Test Facility (FFTF). The scope focuses on the DHX blowers and drive train, inert gas blowers, H and V containment isolation valves, and the Surveillance and In-service Inspection (SISI) transporter and trolley. For each type of equipment, the discussion includes a summary of the design and system function, installation history, preoperational acceptance testing procedures and results, and unusual events and resolutions

  3. Testing of the AP600 automatic depressurization system

    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

    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)

  5. High level radioactive waste vitrification process equipment component testing

    Remote operability and maintainability of vitrification equipment were assessed under shielded-cell conditions. The equipment tested will be applied to immobilize high-level and transuranic liquid waste slurries that resulted from plutonium production for defense weapons. Equipment tested included: a turntable for handling waste canisters under the melter; a removable discharge cone in the melter overflow section; a thermocouple jumper that extends into a shielded cell; remote instrument and electrical connectors; remote, mechanical, and heat transfer aspects of the melter glass overflow section; a reamer to clean out plugged nozzles in the melter top; a closed circuit camera to view the melter interior; and a device to retrieve samples of the glass product.

  6. Operability test procedure [Tank] 241-SY-101 equipment removal system

    The 241-SY-101 equipment removal system (ERS) consists of components, equipment, instrumentation and procedures that will provide the means to disconnect, retrieve, contain, load and transport the Mitigation Pump Assembly (MPA) from waste Tank 241-SY-101 to the Central Waste Complex (CWC). The Operability Test Procedure (OTP) will test the interfaces between ERS components and will rehearse the procedure for MPA removal and transportation to the extent they can be mocked-up at the CTF (Cold Test Facility). At the conclusion of the OTP, the ERS components and equipment will be removed from the CTF, entered into the Component Based Recall System (CBRS), and stored until needed for actual MPA removal and transportation

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

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


    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

    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

    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

    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

  17. Automatic WSDL-guided Test Case Generation for PropEr Testing of Web Services

    Konstantinos Sagonas


    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

    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

  20. An equipment test for grading lumber by transverse vibration technique

    Marcelo Rodrigo Carreira


    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.

  1. An SDRAM test education package that embeds the factory equipment into the e-learning server

    Jose M. M. Ferreira


    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

    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)

  3. Ultrasonic testing equipment for nondestructive examination of welds

    By means of the ultrasonic testing equipment the longitudinal-weld or spiral-weld large-size pipes welded by the submerged arc method can be examined for lonitudinal and transverse discontinuities. The search units are radialsymmetrically arranged in a testing spider. Two search units each, mounted opposits one another with respect to the weld, serve to find the transverse discontinuities whereas one search unit each, placed before and behind these couples, serves for detection of lonitudinal flaws. As search units, simple angle beam search units, straight beam search units, or dual search units may be used. (RW)

    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.

  6. Learning Techniques for Automatic Test Pattern Generation using Boolean Satisfiability

    Liu Xin


    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.

  7. High Temperature Calcination - MACT Upgrade Equipment Pilot Plant Test

    Richard D. Boardman; B. H. O& #39; Brien; N. R. Soelberg; S. O. Bates; R. A. Wood; C. St. Michel


    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

The architecture of the system is based around a local bus which comprises a central unit and its memory; a programmable pulse generator; a switching circuit to test and control the various paths; and a unit to communicate with the acquisition system

  10. Validation Testing for Automated Solubility Measurement Equipment Final Report

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


    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

    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

  12. STS-88 crew goes through Crew Equipment Interface Testing


    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

    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

    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

    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

    Junli Zhang


    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

    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.

  12. Automatic testing technologies for I and C systems for nuclear power plants

    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

    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

    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

    Protzel, Peter W.


    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

    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

    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)

  1. Formal Verification of Digital Protection Logic and Automatic Testing Software

    - 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)

    Raamesh, Lilly


    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.

    K. Kovac


    Full Text Available Many factors that influence radiated emission measurement exist. Except of factors relative to measuring chain "test site - antenna - receiver" there are some factors caused by operating personnel like inappropriate configuration of tested equipment, etc. Tested equipments contain generally attached cables of different length; the longer ones shall be shortened by folding into a bundle. The aim of this paper is to analyze the behavior of such cables and its influence on results of radiated emission measurement.

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

    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

    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

  19. Automatic Web-Based, Radio-Network System To Monitor And Control Equipment For Investigating Gas Flux At Water - Air Interfaces

    Duc, N. T.; Silverstein, S.; Wik, M.; Beckman, P.; Crill, P. M.; Bastviken, D.; Varner, R. K.


    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.

  1. Guidelines for Electromagnetic Interference Testing of Power Plant Equipment: Revision 3 to TR-102323

    J. Cunningham and J. Shank


    To continue meeting safety and reliability requirements while controlling costs, operators of nuclear power plants must be able to replace and upgrade equipment in a cost-effective manner. One issue that has been problematic for new plant equipment and especially for digital instrumentation and control (I&C) systems in recent years is electromagnetic compatibility (EMC). The EMC issue usually involves testing to show that critical equipment will not be adversely affected by electromagnetic interference (EMI) in the plant environment. This guide will help nuclear plant engineers address EMC issues and qualification testing in a consistent, comprehensive manner.

  3. Seismic tests of gloveboxes and equipment for plutonium-uranium mixed oxide fuel fabrication

    Although the seismic calculation for the gloveboxes in the plutonium fuel fabrication facilities has been carried out, the seismic test has not yet been performed. Therefore, a series of the seismic test of gloveboxes and the equipments in them was carried out. The purpose of the test was as follows. Investigation of the dynamic motion of gloveboxes and the equipments in them when an earthquake occurs, investigation of the confining ability of gloveboxes after an earthquake occurs, and investigation of the reliability of the analytical procedure by comparing the results of seismic test with those of the dynamic analysis. For the test, the upper glovebox, the lower glovebox and the model frame supporting the upper glovebox were used. The material transporting equipment was in the upper glovebox, and the pressing equipment was in the lower glovebox. Impulse test, free vibration test, sweep test, step by step test, earthquake test and leak test were carried out. The natural frequency and damping coefficient were determined, and the maximum mode of response acceleration to earthquake waves was obtained. In the leak test, the gloveboxes were normal. Generally the calculated values agreed with the experimental values. (Kako, I.)

  12. A Proposal for Automatic Testing of GUIs Based on Annotated Use Cases

    Pedro Luis Mateo Navarro


    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.

  1. Dispensing Equipment Testing with Mid-Level Ethanol/Gasoline Test Fluid: Summary Report

    Boyce, K.; Chapin, J. T.


    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.

  2. The ALDB box: automatic testing of cognitive performance in groups of aviary-housed pigeons.

    Huber, Ludwig; Heise, Nils; Zeman, Christopher; Palmers, Christian


    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

    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

    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

    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.)

  11. Fully automatic sample treatment by integration of microextraction by packed sorbents into commercial capillary electrophoresis-mass spectrometry equipment: application to the determination of fluoroquinolones in urine.

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


    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%.

  20. Soundness confirmation through cold test of the system equipment of HTTR

    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.

    Stefanko, D.; Langton, C.


    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

    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

    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.

  14. Development and Beam Tests of an Automatic Algorithm for Alignment of LHC Collimators with Embedded BPMs

    Valentino, G; Gasior, M; Mirarchi, D; Nosych, A A; Redaelli, S; Salvachua, B; Assmann, R W; Sammut, N


    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

    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

    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.

    Cho, M. S.; Kang, Y. H.; Kim, B. G. and others


    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.

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

    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)

    Yokono, Y. [Non-Destructive Inspection Co. Ltd., Osaka (Japan)


    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.

    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.

  3. Experience of manual periodic testing and development of automatic test devices

    During more than two decades experience has been gained in the field of process control and instrumentation using signal noise analysis applied to measurements at Swedish nuclear power plants. The methods developed and employed cover areas like: - Sensor and component status test in safety systems during operation, - Monitoring of BWR-stability during start-up, - Thermal time constant analysis on irradiated fuel, - Monitoring of instrument tube vibrations during operation, Self-diagnosing neutron detectors. Together with stationary surveillance systems like SOLNAS for Early Warning based on spectral analysis and Pattern Recognition we use a mobile mini-computer twin station and PC/AT sets. Further theory development goes hand in hand with experimental results obtained through measurement campaigns. In the following some of the work under progress, demonstrated or already applied is described and the results are reported correspondingly

    Shan, Qirang; Bu, Man


    The infrared radiation characteristics of IR-strengthened equipment (ISE) fixed on a target drone have been tested using on-the-spot measurements of ISE as a point source taken for different structures and ground states. The instruments and their combination in the IR test system are briefly described, and experimental methods are presented for testing the following ISE IR radiation characteristics: IR spectrum characteristics, the distribution of IR energy with respect to time and space, and the effective radiation intensity under manifold working states. The results indicate that the data have good repetitiveness and the parameters have very close correlativity. A test system and method used to develop new kinds of IR radiation sources are described.

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

    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

    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

  10. Site characterization and validation - equipment design and techniques used in single borehole hydraulic testing, simulated drift experiment and crosshole testing

    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.
