ACX proposes an innovative new process for the manufacture of smart structures using a High Velocity Oxy-Fuel (HVOF) thermal spray process. This simple, multi-step process will be capable of depositing electroded piezoceramic coatings. The coatings will be poled while still hot, reducing poling times and voltages while increasing poling efficiency. Process times will be extremely short. The pr ...

Eikos LLC will evaluate two approaches, millimeter waves and opto-acoustics, for locating edges and holes in substructure that are hidden under exterior panels and skins during aircraft assembly. These devices will work in a camera-like fashion to allow non-destructive remote imaging. Eikos has developed promising approaches to both techniques that have the potential to be low cost and easy to u ...

Eikos LLC will modify and enhance the chemistry of the NRL developed phthalonitrile resin to meet the 700F TOS requirements of high temperature RTM and RFI aerospace composites. Eikos is intimately familiar with the chemistry of the phthalonitrile resin because of our efforts to scale the production of the current bases resin from the laboratory to the pilot plant. Eikos has teamed with McConne ...

STEAM GENERATOR TUBES REPRESENT A UNIQUE PART OF THE REACTOR COOLANT SYSTEM (RCS). LEAKAGE FROM ANY OTHER PART OF THE RCS IS CAPTURED BY THE CONTAINMENT BUILDING, BUT STEAM GENERATOR TUBE LEAKAGE IS TRANSPORTED OUT OF THE CONTAINMENT BUILDING ALONG WITH THE STEAM, WHICH IS NORMALLY UNCONTAMINATED. STEAM GENERATOR TUBES, CONSEQUENTLY, DESERVE, AND RECEIVE SPECIAL CONSIDERATION. THE ASSURANCE OF STE ...

ON FEBRUARY 9, 1991, AT THE MIHAMA UNIT 2 NUCLEAR POWER STATION, OPEARTED BY KANSAI ELECTRIC CORPORATION, A STEAM GENERATOR TUBE RUPTURED AND RELEASED APPROXIMATELY 9,000 GALLONS OF REACTOR COOLANT INTO THE SECONDARY SYSTEM. THE LEAKAGE CAUSED A RAPID DEPRESSURIZATION OF THE REACTOR COOLANT SYSTEM, WHICH RESULTED IN AN AUTOMATIC REACTOR TRIP AND ACTUATION OF THE HIGH PRESSURE SAFETY INJECTION SYST ...

The following proposal describes an affordable modular sensor system which can be used for tactical oceanography. The system, referred to as MiniMOP (Miniature Multipurpose Optical Pod) is teh integrated sensor package capable of measures fluorometry, luminometry, transmissiometer, salinity, tempature and water depth. The sensor package will remain module for mounting in any small AUV but develo ...

An innovative deep submergence low frequency, broadband transducer forefficient operation is presented. The transducer uses a multiport concept (U.S. Patent 5, 184, 332) which allows back radiation to arrive in phase with the forward radiation and allows broadband depth independent operation. Because the system utilizes Helmholtz resonators, low frequency operation can be achieved. A number of ...

THIS WORK IS TO DEVELOP A METHOD TO IMPROVE THE ABILITY OF THE USNRC TO EVALUATE THE OPERATIONAL SAFETY SIGNIFICANCE OF OCCURANCES AT NUCLEAR POWER PLANTS. PERHAPS THE AREA OF GREATEST SAFETY SIGNIFICANCE IS HUMAN PERFORMANCE, BUT THE TECHNIQUES USED BY NRC DO NOT EVALUATE HUMAN PERFORMANCE IN ANY SYSTEMIC WAY. THE WORK IS PROPOSED TO BE PERFORMED IN THREE STAGES, AND BUILDS ON METHODS THAT HAVE B ...
