CURRENT ACTIVITY WITHIN THE NRC AND THE NUCLEAR INDUSTRY SEEKS TO EXPLOIT THE BENEFITS OF PRA IN RISK-BASED APPROACHES TO RELIEVE REGULATORY BURDEN ON THE ECONOMICALLY THREATENED NUCLEAR POWER PLANTS. THE ACCIDENT PREVENTION GROUP HAS BEEN DEVELOPING THE CONCEPT OF AN INTEGRATED RISK MANAGEMENT PROGRAM (IRMP) TOWARD SUCH GOALS. A KEY ELEMENT OF AN IRMP IS AN "OPERATIONAL RISK MODEL" OF THE NPP THA ...

The ISO Format Open Document standards 11, 26 and 36 describe a language for standard word processor systems. To implement such a system there are a number of challenges to overcome. The challenge of reusing logical constituent parts of a document and the difficulty of constructing a viable user interface are addressed in the research work proposed below. In addition the research will address t ...

The proposed effort is to design a space-qualified dual-frequency GPS/GLONASS receiver with enhanced capabilities for atmospheric remote sounding. While such soundings have been performed using GPS-only receivers, a space-based GPS/GLONASS receiver would be superior in terms of coverage and integrity cross- checking, as well as the ability to process the unencrypted GLONASS L2 signal. This design ...

Two-dimensional measurement machines, such as microlithography and computed tomography systems, are subject to distortions in the measurement field due to imperfections in their hardware and software. Certified methods to characterize and quantify such distortions are urgently needed. An innovative self- calibrating scheme is tendered which eliminates the disadvantages of previous self-calibration ...

The overall quality and the comprehensive strength, in particular, of concrete are critically dependent on the water content in the concrete mixture. It is also essential to know if the concrete has reached a stage of moisture equilibrium before surface finishes such as paint or carpet can be applied. At present, no reliable method or easy-to-use instrument exists for determining the moisture co ...

The increased emphasis on mass screening for early detection of cancer has created a demand for effective quality assurance of medical radiography equipment. This is particularly true in mammography where indications of cancer are subtle and the image quality varies strongly with the x-ray technique used for the examination. Many studies clearly indicate that well calibrated and aligned equipmen ...
