  1. 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.

    SBC: Daniel & Associates Inc.            Topic: N/A

    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 ...

  3. EXTENDED FATIGUE LIFE EVALUATION METHODS FOR AGED LWR COMPONENTS

    SBC: O'donnell Consulting Engineers            Topic: N/A

    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 ...

  4. FUNCTIONAL CONDITION OF SOLENOID-OPERATED VALVES USED IN NUCLEAR POWER PLANT SAFETY APPLICATIONS

    SBC: Pentek Inc.            Topic: N/A

    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 ...

    SBIR Phase I 1989 Nuclear Regulatory Commission
  7. DEVELOPMLENT OF A LAUNDRY MONITOR FOR DETECTION OF HOT PARTICLE CONTAMINATION

    SBC: Shonka Research Associates            Topic: N/A

    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.

    SBIR Phase II 1990 Nuclear Regulatory Commission
  8. IMPROVED NEUTRON SPECTROMETER AND EXPOSURE METER

    SBC: Shonka Research Associates            Topic: N/A

    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 ...

    SBIR Phase I 1991 Nuclear Regulatory Commission
  10. QUANTIFICATION OF CONSERVATISMS IN SEISMIC RISK ESTIMATES THROUGH ENGINEERING ADVANCEMENT OF SEISMIC PRA

    SBC: Risk Engineering Inc.            Topic: N/A

    SIGNIFICANT CONSERVATISM IN MODERN SEISMIC PRA DERIVES FROM SIMPLIFICATIONS IN GROUND-MOTION CHARACTERIZATION AT THE INTERFACE OF SEISMIC HAZARD AND FRAGILITY METHODOLOGIES. THIS CONSERVATISM ARISES BECAUSE A SINGLE COMPOSITE-MAGNITUDE, BROAD-BAND, GROUND-MOTION SPECTRUM IS USED TO DERIVE FRAGILITY FUNCTIONS, WHEREAS THE MAJORITY OF MOTIONS CONTRIBUTING TO SITE HAZARD HAVE (LESS-DAMAGING) NARROW-B ...
