OZONE IS A VALUABLE ALTERNATE TO CHLORINE FOR THE DISINFECTION OF WASTEWATER AND WATER. IT GENERATES NO CHLORINATED ORGANICS AND LEAVES NO RESIDUALS HARMFUL TO HUMAN HEALTH OR TOXIC TO MARINE LIFE. THE OZONE REACTS THROUGH FREE RADICAL OR POLAR MECHANISMS UNDER WATER TREATMENT CONDITIONS DEPENDING ON PH AND OTHER FACTORS. THE MECHANISM OF BACTERIAL DISINFECTION IS NOT COMPLETELY UNDERSTOOD. THE OZ ...

OF REACTOR THERMAL-HYDRAULICS CODES. THESE CODES HAVE INTERNATIONAL APPLICABILITY. TRADING THESE CODES, WITH APPROPRIATE SUPPORT, TO OTHER COUNTRIES IN EXCHANGE FOR USEFUL DATA OR OTHER RESOURCES WOULD ENHANCE THEIR UTILITY AND REDUCE THE COST TO THE U.S. OF GENERATING EQUIVALENT DATA. THE OBJECTIVE OF THE PROPOSED EFFORT IS TO PROVIDE A SOUND TECHNICAL BASIS FOR SUCH AN EXCHANGE BY: IDENTIFYING C ...

COMMON CAUSE FAILURE ANALYSIS (CCFA) IS AN IMPORTANT ELEMENTOF A COMPLETE PROBABILISTIC RISK ASSESSMENT (PRA) SINCE COMMON CAUSE FAILURE IS OFTEN A DOMINANT FACTOR IN THE RISK POSED TO PUBLIC HEALTH AND SAFETY FROM NUCLEAR POWER PLANT ACCIDENTS. A MAJOR PROBLEM ASSOCIATED WITH PERFORMING A CFFA IS THE ABSENCE OF SUPPORTING QUALITATIVE OR QUANTITATIVE COMPONENT FAILURE DATA. EXTENSIVE AMOUNTS OF CO ...

A TECHNOLOGY KNOWN AS THE HYDROSUNDER PROCESS, INVENTED BY THE PROPOSER, REMOVES OILY SUBSTANCES FROM SUBSTRATE MATERIALS BY AN ENTIRELY NEW METHOD. IT WAS DEVELOPED AS AN OIL AND SAND PROCESS FOR OIL MINING PROJECTS. THE METHODREPLACES THE OILY LAYER IN CONTACT WITH THE SUBSTRATE, WITH A HYDRATION LAYER THAT IS ESSENTIALLY COMPLETE, THUS ISOLATING THE OILY COMPOUNDS FROM THE SUBSTRATE. THE PROCES ...

THIS RESEARCH WILL DETERMINE THE CHARACTERISTICS OF FATIGUE INITIATION LIFE, FATIGUE CRACK GROWTH RATES, AND SLOW-STABLECRACK EXTENSIONS FOLLOWING A POST-IRRADIATION ANNEAL. FATIGUE INTITIATION LIFE WILL BE DETERMINED WITH SMOOTH SPECIMENS OF 308 STAINLESS STEEL WHICH HAVE BEEN ANNEALED AND THEN CYCLED IN PRESSURIZED, HIGH-TEMPERATURE WATER. SUBMERGED ARC WELD STEEL (LINDE 80 FLUX) WILL BE PARTIAL ...

THE RESEARCH ACTIVITY PRESENTED IN THIS PROPOSAL FOCUSES ON THE DEVELOPMENT OF SIMPLE RAPID TESTS PROCEDURES TO PREDICT TRANSPORT OF WASTE LIQUIDS THAT CONTAIN ORGANIC COMPOUNDS THROUGH CLAYEY SOIL LINERS OVER EXTENDED TIME PERIODS. THESE PROCEDURES REFLECT BULK POROSITY AND PORE-SIZE DISTRIBUTION CHARACTERISTICS OF SPECIFIC ORGANIC COMPOUND CLAY PAIRS. THE PROJECT WILL ASSESS THE FEASIBILITY OF P ...
