Fuel element component procurement requires a considerable lead time (three to four months after design is completed). Collection of data and statistical analyses to evaluate the performance of these components takes even longer. There is often reluctance to disturb the status quo in these matters without engineering recommendations; these are usually not given until the parameters are defined quantitatively with a high statistical level of significance. The purpose of this analysis is to take a qualitative look at material discharged to determine what conclusions can be drawn concerning the performance of C-64-F and X-8001-F clad fuel elements.

A description of the IBM-704 subroutineTRICE, which evaluates a single integral by means of the trapezoidal rule approximation is given. In the calculational procedure, the integration step is halved until the desired degree of convergence is reached or until a preset maximum number of steps is exceeded. A maximum of ten different integrands may be used in any one calling program. The subroutine is written in FORTRAN. (auth)

The Neptune device was detonated underground in a room approximately 12 x 17 x 10 ft, at the end of a hooked drift. The yield was 115 plus or minus 15 tons. The shot and its effects are described and the major contributions of the data to the theory and prediction of cratering phenomenology are indicated. (W.D.M.)

Ultrasonic cleaning uses high-frequency sound waves to induce cavitation within a cleaning, medium. During cavitation, millions of small bubbles form and collapse, resulting in agitation proportional to the energy put into the solution. The making and breaking of these bubbles produce the scrubbing action associated with ultrasonic cleaning.
