PREDICTING THE RATE OF SOIL WATER MOVEMENT AND THE IMPACT OFAGRI-CHEMICALS ON WATER RESOURCES IS VITALLY IMPORTANT TO MANAGING AGRICULTURE, FOR OPTIMIZING PRODUCTIVITY AND MINIMIZING ENVIRONMENTAL IMPACT. SOPHISTICATED MODELS FOR MAKING SUCH PREDICTIONS ARE AVAILABLE, BUT DATA ON SOIL HYDRAULIC PROPERTIES ARE DIFFICULT AND OFTEN EXPENSIVE TO OBTAIN. IN FACT, AT DEPTHS BELOW THE ROOT ZONE THERE IS ...

WE PROPOSE TO DEVELOP A SIMPLE TO USE, QUANTITATIVE DEVICE TO ACCURATELY MEASURE SOIL WATER CONTENT WITH SUFFICIENT RESOLUTION TO DEFINE WETTING FRONTS DUE TO RAIN EVENTS IN DEPTH PROFILES. THIS GEOPHYSICAL TOOL SENSES CHANGE IN THE ELECTROMAGNETIC ENVIRONMENT, SPECIFICALLY THE DIELECTRIC CONSTANT OF THE SOIL, WHICH IS DIRECTLY RELATED TO SOIL WATER CONTENT. THE SOIL WATER CONTENT PROFILING DEVICE ...

MOTOR OPERATED GATE VALVE OPERABILITY PROBLEMS AND FAILURES AT NUCLEAR POWER PLANTS ARE A MAJOR SAFETY CONCERN AS STATEDIN NRC IE BULLETIN 85-03 AND GENERIC LETTER 89-10. THIS PROPOSAL IS AIMED AT IMPROVING GATE VALVE PERFORMANCE BY (1) DEVELOPING COMPREHENSIVE PERFORMANCE PREDICTION MODELS FOR USE OVER A RANGE OF OPERATING CONDITIONS, (2) DEFINING LIMITS, BASED ON SPECIFIC DESIGNS, BEYOND WHICH E ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

TWO APPROACHES WILL BE EXAMINED TO SIGNIFICANTLY IMPROVE THESENSITIVITY OF LAUNDRY MONITORS TO DETECT AND SPECIFY LOCATION OF HOT PARTICLES ON LAUNDERED GARMENTS. THESE PROPOSED TECNIQUES HAVE HIGH POTENTIAL FOR DETECTING BOTH LOW ENERGY BETA AND ALPHA PARTICLE RADIATION AS WELL AS IMPROVING SENSITIVITY BY REDUCING BACKGROUND COUNT RATE.

THE UNCERTAINTY IN MEASURING NEUTRON DOSE EQUIVALENT RATES RESULTS IN UNCERTAINTY IN ASSIGNMENT OF THE PROPER DOSE TO OCCUPATIONAL RECORDS AND CAN RESULT IN IMPROPER IMPLEMENTATION OF CONTROLS TO LIMIT THE EXPOSURE. A NOVEL PORTABLE NEUTRON SPECTROMETER IS PROPOSED WHICH WILL REDUCE THE UNCERTAINTY OF SUCH MEASUREMENTS TO LESS THAN 20%. MANYCOMPONENTS OF THIS DEVICE ARE COMMERCIALLY AVAILABLE. SYS ...

THE OBJECTIVE OF THE PHASE I RESEARCH IS TO DETERMINE THE TECHNICAL FEASIBILITY OF THE DEVELOPMENT OF A LONG RANGE RADIOACTIVE PLUME TRANSPORT MODEL/CODE FOR THE NRC. THIS CODE WOULD BE USED TO SIMULATE THE MOVEMENT, DISPERSION, DECAY, AND DEPOSITION OF RADIONUCLIDES RELEASED FROM SEVERE NUCLEAR REACTOR ACCIDENTS, SUCH AS THE CHERNOBYL ACCIDENT. IT IS DESIRED THAT ALL RELEVANT PHYSICAL AND CHEMICA ...

XMCO HAS IDENTIFIED AN OPPORTUNITY TO CONDUCT RESEARCH TO DETERMINE THE FEASIBILITY OF DEVELOPING A COUNTY AGENT ADVISOR SYSTEM (CAAS). THIS INNOVATIVE CONCEPT WOULD INVESTIGATE THE APPLICATION OF ARTIFICIAL INTELLIGENCE TECHNOLOGY, SPECIFICALLY HYPERMEDIA TECHNOLOGY WITH EMBEDDEDEXPERT SYSTEMS, TO THE ENVIRONMENT AND REQUIREMENTS OF COUNTY AGENTS. THIS MEETS A USDA NEED FOR INNOVATIVE TECHNOLOGY ...
