    The Risk Assessment Review Group was organized by the U.S. Nuclear Regulatory Commission on July 1, 1977, with four elements to its charter: (1) Clarify the achievements and limitations of WASH-1400, the "Rasmussen Report." (2) Assess the peer comments thereon, and responses to those comments. (3) Study the present state of such risk assessment methodology. (4) Recommend to the Commission how (and whether) such methodology can be used in the regulatory and licensing process. View full abstract»

    By fitting a lognormal distribution to the data of Messenger and Steele a statistical analysis derives a formula for the survival probability, with 90 percent confidence, of a silicon transistor exposed to the neutron flux ¿ as: Ps(¿)=Fn[ln(C.T.F.-1)+ln(fTmin/ßmin/¿)+16.38/0.493] where Fn is the standard normal cumulative distribution function, C.T.F. is the circuit tolerance factor, fTmin is the minimum gain band width product specified by the manufacturer and ßmin is the minimum current gain specified by the manufacturer. The present analysis is similar to the previous one except that the analysis here accounts for the fact that a lognormal distribution does not exactly fit the data. The formula shown above differs from the one presented in reference 2 in that their denominator of 0.444 has been replaced by 0.493. The new denominator can increase previously estimated failure probabilities by a factor of 2.5. The method shown here is generally applicable to cases where distributions other than the lognormal ones are fitted to a set data. View full abstract»

  • Direct Three-Dimensional Image Reconstruction from Divergent Rays

    The solutions to the image reconstruction problem, in two and three dimensions, for both parallel and divergent ray geometries, are presented within a general linear reconstruction framework. It is shown that, with suitable parameterizations, each of these solutions reduces to a "convolve-and-backproject" algorithm. The exact solution to the three-dimensional divergent ray geometry problem is a new result and is treated in detail. This problem arises when the sensors are located around the object region in three-dimensional space, and the measurement rays diverge (i.e., fan out) from the individual sources. An approximation to the exact solution has been made in order to derive convenient and practical convolving functions for this geometry. View full abstract»

  • Dissolution of Palladium and Platinum from Automotive Catalysts

    Automotive exhaust gas catalysts contain palladium and platinum as the active material on an alumina substrate. Experiments were conducted to determine the amount of palladium and platinum that could be leached from fresh and aged automotive catalysts under various conditions. The conditions included soaking the catalyst samples in rain water to simulate environmental leaching from discarded catalysts and in dilute hydrochloric acid to simulate the dissolution of noble metals from swallowed catalysts. To obtain the necessary sensitivity for measuring microgram quantities of these noble metals in the leachates, radiochemical techniques were used. The results indicate that only very small amounts of noble metals are leached from fresh catalysts; the extent of dissolution depends upon catalyst pretreatment and the leaching solution. The dissolution of noble metals from aged catalysts (80,000-km vehicle tests) is one tenth that of fresh catalysts. View full abstract»
