  • A Sun-based data acquisition and control (DAQ) system has been designed for PETRRA, a whole-body positron camera using large-area BaF{sub 2}-TMAE detectors. The DAQ system uses a high-speed digital I/O card (S16D) installed on the S-bus of a SPARC10 and a specially-designed Positron Camera Interface (PCI), which also controls both the gantry and horizontal couch motion. Data in the form of different types of 6-byte packets are acquired in list mode. Tests with a signal generator show that the DAQ system should be able to cater for coincidence count-rates up to 100 kcps. The predicted count loss due to themore » DAQ system is {approximately}13% at this count rate, provided asynchronous-read based software is used. The list-mode data acquisition system designed for PETRRA could be adapted for other 3D PET cameras with similar data rates.« less
  • The NDE Section of the Lawrence Livermore National Laboratory (LLNL) provides Laboratory programs with tools needed for the inspection and characterization of materials, components and complete assemblies. X-ray CT is being used to complement conventional radiography as a three-dimensional means of quantitatively measuring material density, uniformity, and flaw dimensions. Laboratory inspection requirements demand diagnostic images with spatial resolutions on the order of tens of micrometers and better than 1% contrast sensitivity. In response to these needs, we are building an experimental CT scanner to develop the technology of high-resolution CT imaging. The scanner uses a charge-coupled device (CCD) camera tomore » acquire two-dimensional images of low density materials. Our initial goal is to achieve quantitative density measurements over a 5-cm/sup 3/ sample with 30-50 /mu/m spatial resolution. This paper discusses the CT system we are building and reviews the criteria and issues associated with the design of high-resolution CT scanners. After briefly describing our scanner's hardware configuration, we discuss four important aspects of CT data acquisition. These include choice of scan geometry, source energy, sampling rates, and signal processing to improve the integrity of the acquired data. Next, we stress the necessity for correlating CT system performance (spatial resolution and contrast sensitivity) with measurable parameters of the system. We present analytical results describing the relationship between the system point spread function (PSF) and source-detector blur, as well as the relationship between contrast sensitivity and system noise. We conclude by discussing typical applications and results of our CT scanner. 8 refs.« less
  • A recent report was published by the U.S. Nuclear Regulatory Commission – Industry-Average Performance for Components and Initiating Events at U.S. Commercial Nuclear Power Plants, NUREG/CR-6928. That report characterized industry performance (generally covering 1998 – 2002) for 51 component types found in commercial nuclear power plants. For example, for emergency diesel generators, three failure modes were identified: fail to start and reach rated speed and voltage, fail to load and run for one hour, and fail to run beyond one hour. Data from the U.S. industry contained in the Equipment Performance and Information Exchange (EPIX) database maintained by The Institutemore » for Nuclear Power Operations were used to evaluate the failure probabilities and rates for these failure modes, covering 1998 – 2002. The software package Reliability and Availability Database System (RADS) was used to search and process the EPIX data. In addition, train test and maintenance unavailability was characterized for 34 train types. As a follow-on effort to this report, several components will be analyzed in more detail each year. These detailed studies include more recent data and analyze various subcategories such as manufacturer, system, size and type (as applicable). In addition, engineering insights such as piece part contribution to each failure mode and failure cause will be determined. This paper summarizes the preliminary results for emergency diesel generators. EPIX data coverage was expanded to include 1998 – 2007 and reliability results were compared with unplanned demand performance (bus under voltage events requiring the emergency diesel generator to start, load and run) over the same period. In addition, performance by manufacturer was evaluated. Finally, piece part contributions and failure causes were determined for each failure mode.« less
  • This report summarizes work done to verify the component, failure mode, and method of detection information provided in the Equipment Performance Information Exchange (EPIX) to support implementation of Mitigating Systems Performance Indices. This task is to select reports from EPIX and determine if their categorization as MSPI or non-MSPI failures is consistent with the development of unreliability baseline failure rates, and whether this significantly affects estimates of plant risk. This review is of all MSPI devices in EPIX that were reported as failures. The components include emergency generators; motor-driven, turbine-driven, and enginedriven pumps; and air and motor-operated valves. The datemore » range for this report includes all MSPI device reported failures from 2003 to the most current EPIX data at the INL (up to the 3rd quarter 2008).« less
  • The characteristics and design of a high-accuracy and high-sensitivity 2-dimensional camera for the measurement of the end-point of the trajectory of accelerated heavy ion beams of positron emitter isotopes are described. Computer simulation methods have been used in order to insure that the design would meet the demanding criteria of ability to obtain the location of the centroid of a point source in the X-Y plane with errors smaller than 1 mm, with an activity of 100 nanoCi, in a counting time of 5 sec or less. A computer program which can be developed into a general purpose analysis toolmore » for a large number of positron emitter camera configurations is described in its essential parts. The validation of basic simulation results with simple measurements is reported, and the use of the program to generate simulated images which include important second order effects due to detector material, geometry, septa, etc. is demonstrated. Comparison between simulated images and initial results with the completed instrument shows that the desired specifications have been met.« less
