Book Description
U.S. Air Force and other agencies which handle, store and transport chemicals, fuels and oxidizers are interested in determining the potential area of hazard posed by the dispersion of vapors generated by accidental spills. This report describes the mathematical models developed to described a variety of source types and the dispersion of vapor clouds/plumes in the atmosphere. Sixteen different source types are modeled including pressurized liquid releases, flashing and aerosol formation, two phase jet releases, explosive releases and releases of high vapor pressure liquids, cryogenic liquids and gases. Dispersion model takes into account the differences in source characteristics, high-than-air density of clouds (due to aerosol presence, temperature or molecular weight). Reactions of the chemicals, if any, .th water vapor in the air are modeled and considered in the dispersion model. Transition from heavy gas dispersion to near neutral density dispersion is modeled without abrupt changes in size or discontinuity in concentrations. Keywords: Heavy gas, Dispersion, Mathematical model, Reaction, Source models, Concentration contours.

Book Description
Probabilistic Safety Analysis (PSA) determines the probability and consequences of accidents, hence, the risk. This subject concerns policy makers, regulators, designers, educators and engineers working to achieve maximum safety with operational efficiency. Risk is analyzed using methods for achieving reliability in the space program. The first major application was to the nuclear power industry, followed by applications to the chemical industry. It has also been applied to space, aviation, defense, ground, and water transportation. This book is unique in its treatment of chemical and nuclear risk.Problems are included at the end of many chapters, and answers are in the back of the book. Computer files are provided (via the internet), containing reliability data, a calculator that determines failure rate and uncertainty based on field experience, pipe break calculator, event tree calculator, FTAP and associated programs for fault tree analysis, and a units conversion code. It contains 540 references and many referrals to internet locations for information. Provides the only free fault tree analysis computer code and reliability database Very comprehensive coverage of chemical and nuclear risks Gives links to the internet
