  1. "EXTENDING A HCLPF-BASED SEISMIC MARGIN REVIEW TO ANALYZE PLANT DAMAGE STATES AND THE ROLE OF HUMAN FACTORS AND NON-SEISMIC FAILURES"

    SBC: Future Resources Associate Inc            Topic: N/A

    TECHNIQUES HAVE RECENTLY BEEN DEVELOPED TO ANALYZE THE 'SEISMIC MARGIN' OF A NUCLEAR POWER PLANT USING THE HCLPF CONCEPT (HIGH CONFIDENCE OF A LOW PROBABILITY OF FAILURE). STARTING WITH AN EARTHQUAKE LEVEL SHOSEN FOR MARGIN REVIEW, THE TECHNIQUE DETERMINES WHETHER THE PLANT CAN OR CANNOT 'WITHSTAND THE REVIEW-EARTHQUAKE WITHOUT CORE DAMAGE. HERE 'WITHSTAND' MEANS 'WITHSTAND WITH A HIGH CONFIDENCE ...

  4. AGING PROCESSES IN NUCLEAR REACTORS

    SBC: Pdi Technology Inc            Topic: N/A

    AS NUCLEAR PLANTS GROW OLDER, ENVIRONMENTAL CONDITIONS MAY AFFECT THE PERFORMANCE OF PLANT CONCRETE AND STEEL STRUCTURES. WE PROPOSE TO DEVELOP A STRATEGY WHICH CAN BE APPLIED TO CONCRETE STRUCTURES. IT WILL BE DIRECTED TOWARDSTHE DEVELOPMENT OF METHODS TO ANALYZE AND UNDERSTAND AGING EFFECTS, INCLUDING THE COMBINED EFFECTS OF TIME, TEMPERATURE, RADIATION, HUMIDITY, STRESS, CHEMICAL ENVIRONMENT AN ...

  5. ASSESSMENT OF RARE EVENT FREQUENCIES OFTEN REQUIRES SIGNIFI-CANT RELIANCE ON EXPERT JUDGEMENT DUE TO THE SCARCITY OF EMPIRICAL DATA.

    SBC: Pickard, Lowe & Garrick Inc.            Topic: N/A

    ASSESSMENT OF RARE EVENT FREQUENCIES OFTEN REQUIRES SIGNIFI-CANT RELIANCE ON EXPERT JUDGEMENT DUE TO THE SCARCITY OF EMPIRICAL DATA. IN THIS WORK, FORMAL MODELS FOR USING THE OPINIONS OF SINGLE AND MULTIPLE EXPERTS WILL BE EVALUATED INLIGNT OF EMPIRICAL DATA. THE OBJECTIVE IS TO SEE TO WHAT EXTENT THE EMPIRICAL DATA "VALIDATES" THE EXPERTS' ESTIMATES, AS WELL AS THE MODELS USED FOR ANALYZING SUCH ...

  6. AUTOMATIC CREATION AND RENODALIZATION OF TRAC-BWR INPUT DECKS

    SBC: Expert-ease Systems            Topic: N/A

    THE OBJECTIVE OF THE PROPOSED RESEARCH IS TO BUILD A USER-FRIENDLY, PERSONAL COMPUTER BASED WORKSTATION FOR PERFORMING TRAC-BWR ANALYSIS. THE SOFTWARE WILL ALLOW A USER TO READ-IN DATA FROM EXISTING TRAC-BWR INPUT DECKS (ASCII), DRAW NODALIZATION DIAGRAM, MODIFY INPUT, AUTOMATICALLY RENODALIZE THE VESSEL, CHAN AND PIPE COMPONENTS, GENERATE INPUT DECK, SUBMIT JOB, BRING BACK PLOTDATA, DISPLAY RESUL ...

  7. BASED ON HEAT RELEASE MONITORING: A DEMONSTRATION PROGRAM

    SBC: Geoscience Ltd            Topic: N/A

    THE PROPOSED PROGRAM CONSISTS OF THE DEVELOPMENT OF A TECHNIQUE AND A SYSTEM TO MEASURE THE RADIOACTIVE DECAY OF OF RADWASTE CONTAINED IN STORAGE CANISTERS, CASKS AND VAULTS. THE SYSTEM BEING CONSIDERED DEALS WITH THE DIRECT MEASUREMENT OF THE AFTERHEAT BEING GENERATED IN THE RADWASTEVOLUMES. THE SYSTEM TO BE USED TO ACCOMPLISH SUCH MEASURE MENTS CONSISTS OF A HEAT FLUX SENSOR ENVELOPE THAT SURROU ...

  8. FACILITATE DEVELOPMENT AND EVALUATION OF FAULT TREES

    SBC: Expert-ease Systems            Topic: N/A

    WORKSTATION AND EXPERT SYSTEM TECHNOLOGIES HAVE A POTENTIAL OF SUBSTANTIALLY FACILITATING THE DEVELOPMENT AND EVALUATIONOF FAULT TREES. INTRODUCING A WORKSTATION PHILOSOPHY WITH AN INTERACTIVE SET OF INTEGRATED SOFTWARE TOOLS ON A LOCAL COMPUTER WILL PROMOTE IMPROVED CONTINUITY IN THE THOUGHT PROCESS DURING A FAULT TREE DEVELOPMENT. THE EXPERT SYSTEM TECHNOLOGY WILL SIMPLIFY THE WAY FAULT TREES AR ...

  9. IN-REACTOR MEASUREMENTS INVOLVING ELECTROCHEMICAL POTENTIAL A NUMBER OF BOILING WATER REACTORS (BWRS) SUGGEST THAT THE WATER CHEMISTRY OF THE PRIMARY COOLANT OF EACH BWR MAY BE UNIQUE WITH RESPECT TO ITS ABILITY TO FACILITATE IGSCC AND/ OR MAY CHANGE

    SBC: Michael Fox            Topic: N/A

    IN-REACTOR MEASUREMENTS INVOLVING ELECTROCHEMICAL POTENTIAL A NUMBER OF BOILING WATER REACTORS (BWRS) SUGGEST THAT THE WATER CHEMISTRY OF THE PRIMARY COOLANT OF EACH BWR MAY BE UNIQUE WITH RESPECT TO ITS ABILITY TO FACILITATE IGSCC AND/ OR MAY CHANGE WITH REACTOR OPERATING TIME OR AGE. THE WORK PROPOSED IS TO GATHER, REVIEW, ORGANIZE, COMPILE, C COMPUTERIZE, AND ANALYZE IN-REACTOR DATA PERTAINING ...

  10. METHODS

    SBC: Structural Analysis            Topic: N/A

    THE PURPOSE OF THE PROPOSED RESEACH IS TO IMPROVE THE SAFETY OF THE PIPING SYSTEMS SUBJECTED TO LOADINGS WITH A WIDE RANGE OF FREQUENCY CONTENT (E.G. PRESSURIZED THERMAL SHOCK, WATER HAMMER, AND SEISMIC LOADINGS). THIS WILL BE DONE BY SHOWING THAT THE SAFETY OF THE PIPING SYSTEMS CAN BE SIGNIFICANTLY IMPROVED BY USING NONLINEAR (INELASTIC) PROCEDURES BECAUSE OF UTILIZATION OF THE SIGNIFICANT ADDIT ...
