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 ...

Development of efficient spray combustors requires a complete understanding of fundamental phenomena that influence and control the overall spray combustion process. Toward this end, detailed experimental characterization of spray flames is essential. This includes measurement of various fuel droplet parameters such as droplet size, velocity, number density, temperature, composition, and droplet ...

This project will extend the microchannel resonator to the level of a few attograms, which will allow measurement of individual particles as small as 10 nanometers with unprecedented resolution. The Phase I effort will prove the feasibility of this approach by miniaturizing the MEMS sensors, thereby improving their intrinsic mass sensitivity up to 100-fold; and by simultaneously measuring the sens ...

THERE IS A NEED FOR AN UNATTENDED GAS CHROMATOGRAPH THAT CANMAKE CONTINUOUS MEASUREMENTS OF CARBON DIOXIDE ON SURFACE BUOYS OR SHIPS OF OPPORTUNITY. AN INNOVATIVE REAL TIME, LOWPOWER, AND INEXPENSIVE SURFACE ACOUSTIC WAVE (SAW) RESONATOR-BASED GAS CHROMATOGRAPH IS PROPOSED THAT OFFERS THE UNIQUE FEATURES OF RUGGED CONSTRUCTION, SMALL SIZE, AND LOW POWER AND GAS CONSUMPTION. THE UNIQUE IMPLEMENTATI ...

The specific problem addressed by the proposed research is the development of a scanner for storage phosphor plates with significantly better positional and intensity accuracy than the current state of the art. The new scanner will be based on the use of a "scanning head" scanning approach which is more simple, accurate, and stable than the approaches previously used. This results in stable and ...

THERE IS A NEED TO REDUCE DOLPHIN BYCATCH IN THE TUNA PURSE SEINE FISHERY IN THE ETP AND IMPROVE THE SEARCHING EFFICIENCY FOR TUNAS NOT ASSOCIATED WITH DOLPHINS. ARETE PROPOSES TO DESIGN IN PHASE 1 A PROTOTYPE AIRBORNE PASSIVE DAYTIME MULTISPECTRAL IMAGING SYSTEM FOR IMPROVING THE SEARCHING EFFICIENCY FOR TUNAS NOT ASSOCIATED WITH DOLPHINS. THIS EFFORT INCLUDES AIRBORNE COLLECTION OF OCEAN VIDEO D ...

Technology research and development in such areas as next-generation atomic clocks, quantum information processing with trapped ions, and atomic spectroscopy is impeded by the lack of commercially available laser sources that meet the required specifications of wavelength tuning range, output power, frequency-stability and reliability. Arete Associates is developing frequency-stable Optically Pump ...

The purpose of this project is to implement the process for a new method for the measurement of LED performance, but in a form that is low-cost, integrated, and easy-to-use, so that the barrier to entry is as low as is possible.
