  • Control Decisions for Flammable Gas Hazards in Waste Transfer Systems
    2000
    Co-Authors: L.j. Kripps
    Abstract:

    This report describes the control decisions for flammable Gas Hazards in waste transfer systems (i.e., waste transfer piping and waste transfer-associated structures) made at control decision meetings on November 30, 1999a and April 19, 2000, and their basis. These control decisions, and the analyses that support them, will be documented in an amendment to the Final Safety Analysis Report (FSAR) (CHG 2000a) and Technical Safety Requirements (TSR) (CHG 2000b) to close the Flammable Gas Unreviewed Safety Question (USQ) (Bacon 1996 and Wagoner 1996). Following the Contractor Tier I review of the FSAR and TSR amendment, it will be submitted to the US. Department of Energy (DOE), Office of River Protection (ORP) for review and approval. The control decision meeting on November 30, 1999 to address flammable Gas Hazards in waste transfer systems followed the control decision process and the criteria for control decisions described in Section 3.3.1.5 of the FSAR. The control decision meeting agenda, attendance list, and introductory and background presentations are included in Attachments 1 through 4. The control decision discussions on existing and other possible controls for flammable Gas Hazards in waste transfer systems and the basis for selecting or not selecting specific controls are summarized in more » this report. « less

  • Control Decisions for Flammable Gas Hazards in Double Contained Receiver Tanks (DCRTs)
    2000
    Co-Authors: L.j. Kripps
    Abstract:

    This report describes the control decisions for flammable Gas Hazards in double-contained receiver tanks (DCRTs) made at control decision meetings on November 16, 17, and 18, 1999, on April 19,2000, and on May 10,2000, and their basis. These control decisions, and the analyses that support them, will be documented in an amendment to the Final Safety Analysis Report (FSAR) (CHG 2000a) and Technical Safety Requirements (TSR) (CHG 2000b) to close the Flammable Gas Unreviewed Safety Question (USQ) (Bacon 1996 and Wagoner 1996) for DCRTs. Following the contractor Tier I review of the FSAR and TSR amendment, it will be submitted to the U.S. Department of Energy (DOE), Office of River Protection (ORP) for review and approval.

  • forecast of geological Gas Hazards for three soft coal seams in gliding structural areas
    Journal of China University of Mining and Technology, 2007
    Co-Authors: Zhirong Wang, Lingxia Chen, Congren Cheng, L I Zhenxiang
    Abstract:

    Abstract Gas outbursts from “three-soft” coal seams (soft roof, soft floor and soft coal) constitute a very serious problem in the Ludian gliding structure area in western Henan. By means of theories and methods of Gas geology, structural geology, coal petrology and rock tests, we have discussed the effect of control of several physical properties of soft roof on Gas preservation and proposed a new method of forecasting Gas geological Hazards under open structural conditions. The result shows that the areas with type III or IV soft roofs are the most dangerous areas where Gas outburst most likely can take place. Therefore, countermeasures should be taken in these areas to prevent Gas outbursts.
