Some considerations in the splitting of interstitial frank loops formed by irradiation

Description: The splitting of interstitial loops formed by irradiation is considered in detail. It is shown that they may split to form obtuse--angled single shear faults on the intersecting (111) planes. A detailed description of the splitting is given in which the interstitial Frank loop is viewed as being made up of perfect dislocation loop and two shears. The detailed description is then considered in the context of the formation of complex loops as are observed in quenching and irradiation studies. Exp… more

Currents density measurements with an ion beam probe

Description: It was shown that by the use of ion beam probing system with the proper detectors experimental expressions can be obtained for v/sub o/ = v/sub o/ (x,y,z) and v/sub d/ = v/sub d (x,y,z). It was also shown that by taking the curl of the difference between the equations, the magnetic field and consequently the plasma current density distribution can be evaluated.

Computational features of the CACECO containment analysis code. [LMFBR]

Description: A code, CACECO, has been written to assist in the analysis of containment situations peculiar to sodium cooled reactors. Typically, these situations involve relatively slow energy release processes and chemical reaction heat. Two examples are given to illustrate some of the code's features. These particular cases illustrate the potential for hydrogen formation in the containment building, but show that time is available to take corrective action. The code is suitable for other problems involvin… more

Pattern recognition at Lawrence Livermore Laboratory

Description: Possible uses of pattern recognition techniques for solving complex scientific problems are discussed, and previous experience in using the pattern recognition computer code RECOG to solve materials problems, specifically in determining the mechanical properties of high explosives, is described.
