THE WORK PROPOSED IN THIS EFFORT IS DIRECTED TOWARDS DETERMINING THE CORRELATION BETWEEN OBSERVED AIRBORNE RADIOIODINE CONCENTRATIONS IN THE AUXILIARY AND FUEL HANDLING BUILDINGS AT TMI-2 FOLLOWING THE ACCIDENT IN 1979 WITH DIURNAL TEMPERATURE VARIATIONS. APPROXIMATELY 5000 MEASUREMENTS WERE MADE DURING THE PERIOD APRIL-JULY, 1979 INDESIGNATED AREAS OF THE AUXILIARY/FUEL HANDLING BUILDING AND THE ...

STRESSES DUE TO PRESSURE AND REPEATED THERMAL CYCLING CAUSE PROGRESSIVE MATERIAL DAMAGE DURING THE OPERATION OF LWR COMPONENTS AND PIPING SYSTEMS. THE PRESENT PRO POSED RESEARCH WOULD IMPROVE THE ACCURACY OF EXISTING S- N FATIGUE EVALUATION METHODS BY COMBINING THEM WITH THE ADVANCED TECHNOLOGY OF CRACK PROPAGATION AND FRACTURE MECH ANICS. ENVIRONMENTAL EFFECTS WILL BE INCLUDED IN THE CRACK PROPAG ...

PENTEK WILL DEVELOP AND TEST A TECHNIQUE TO DETERMINE THE FUNCTIONALITY OF SOLENOID-OPERATED VALVES IN A NUCLEAR POWERPLANT BASED ON THE MEASUREMTNT AND ANALYSIS OF IN-RUSH CURRENT. THE TECHNIQUE WILL BE DEVELOPED SO THAT ALL MEASUREMENTS CAN BE MADE FROM OUTSIDE THE REACTOR BUILDING WITHOUT DISTRUBING ANY ELECTRICAL CONNECTIONS. THE ANALYSIS METHODS WILL BE DEVELOPED FOR ON-LINE USE WITH A PERSON ...

WORKER/DOSIMETER (W/D) GEOMETRY AND RELATIONSHIP TO A SOURCEOF RADIATION CAN PROVIDE FALSE RECORDING OF THE RADATION DOSE RECEIVED BY AN INDIVIDUAL. HENCE, TECHNOLOGY INTERNATIONAL INCORPORATED (TII) IS PROPOSING A TWO PHASE EFFORT WHICH INVOLVES A COMPUTER SIMULATION EXPERIMENT USING GEOMETRIC MODELING IN CONJUNCTION WITH A DOSE COMPUTATION ALGORITHM, FOLLOWED BY PERFORMANCE OF EXPERIMENTEMPLOYIN ...

TII SHALL PROCURE, DESIGN, CONSTRUCT, AND TEST A COMPACT PORTABLE SIMULATOR CAPABLE OF EMULATING NUCLEAR POWER STATION-OPERATOR (NPS-OP) INTERFACES, AND EVALUATE AND TEST VARIOUS INTERFACE DESIGNS. THE SUMULATOR WILL BE DESIGNED FOR OPERATOR TRAINING ON ADVANCED REACTORS AND WILL BE USED IN SIMULATING OPERATORS SCENARIOS AND RECORDING AND DOCUMENTING REAL-TIME INPUT FROM THE OPERATOR. THE SIMULATO ...

We propose to develop an improved Explosively-Formed Penetrator (EFP) warhead that in its basic application projects a slug that pentrates the mine's case and detonates the iner explosive. In an advanced, alternate mode, the warhead will project a penetrator capable of neutralization through deflagration. The alternative mode employs reative intermetallic materials in the warhead's main component, ...

The objective of this project is to develop a lightweight, low drag IR (infra-red light spectrum) suppression system for SOF aircraft. Power, weight and aircraft performance are negatively effected by traditinal suppression concepts and therefore, a new approach to the design problem is required. The proposed design effort will explore a unique design solution to reduce weight and aircraft drag. ...

This proposal outlines an SBIR Phase I supercharged uniflow diesel non-gasoline burning outboard engine design capable of diesel fuel operation and lightweight construction. Inherent specific weight penalties of the Diesel cycle being inversely proportional to specific displacement, indicates a scale reduction of these engines demand greater design discipline relative to the combustion physics th ...

Time Domain Spectroscopy (TDS) is a precision metrology technique which allows the condition of an electrochemical cell or battery to be quantitatively evaluated in real time, obviating the protracted data collection times associated with the more familiar Frequency Response Analysis Method. In the FRA method, the cell's responses to a sequence of sinusoidal excitations are used to estimate the p ...
