In September 1982 the Hazards Control Department of the Lawrence Livermore National Laboratory (LLNL) began a final radiological survey of a former low-level radioactive waste storage area called the Taxi Strip so that the area could be released for construction of an office building. Collection of soil samples at the location of a proposed sewer line led to the discovery of an old disposal pit containing soil contaminated with low-level radioactive waste and organic solvents. The Taxi Strip area was excavated leading to the discovery of three additional small pits. The clean-up of Pit No. 1 is considered to be complete for radioactive contamination. The results from the chlorinated solvent analysis of the borehole samples and the limited number of samples analyzed by gas chromatography/mass spectrometry indicate that solvent clean-up at this pit is complete. This is being verified by gas chromatography/mass spectrometry analysis of a few additional soil samples from the bottom sides and ends of the pit. As a precaution, samples are also being analyzed for metals to determine if further excavation is necessary. Clean-up of Pits No. 2 and No. 3 is considered to be complete for radioactive and solvent contamination. Results of analysis for metals will …

An analytic estimate of beam heat erosion in a highly conductive background is presented and compared to numerical results. Model equations are derived and forced into a self-similar form from which parameter scalings are easily obtained. It is found that erosion in this limit is driven by scattering and is very rapid for high conductivities (greater than or equal to 10/sup 11/) due to the high fraction of current neutralization.

Since the issuance of UCRL 50400 Vol. 23, ENSL and CDRL: Evaluated Nuclear Structure Libraries, errors have been noted in half-lives. Most of these errors were for half-lives represented in exponential form, where the exponent is positive. This situation occurs only when the unit for half-life is years. A few errors were associated with ground states having unknown half-lives. These were incorrectly labeled as stable (i.e., a value of 1.0 E + 50 s was entered). Such ground states are assigned half-lives of 1.0 E - 20 s in the new version of the two data files. In all, we found a total of 65 levels that had incorrect half-lives. These levels and the corrected half-lives are listed.

The computer controlled phase and amplitude detection system measures the instantaneous phase and amplitude of a 1 micro-second 2856 MHz rf pulse at a 180 Hz rate. This will be used for phase feedback control, and also for phase and amplitude jitter measurement. The program, which was originally written by John Fox and Keith Jobe, has been modified to improve the function of the system. The software algorithms used in the measurement are described, as is the performance of the prototype phase and amplitude detector system.

At the time of the 1981 Workshop on Experimental Use of the SLC, we published an extraction scheme for the MINIQUAD final focus (FF) optics. Since then a different FF optics design has been selected. With the same achromat section and outboard telescope, it allows a number of options for the inboard telescope. This note describes the new extraction system and briefly considers electron-electron extraction and the consequences of an extraction kicker malfunction. 4 references, 7 figures, 1 table.

One characteristic of the dislocated worker problem is that a mismatch exists between the number and kinds of jobs offered by employers and the number and kinds of skills possessed by workers in the same geographic area. At the same time, other geographic areas have unfilled job openings and relatively low unemployment rates. Government-assisted worker relocation is one tool of employment policy that might be used to reduce these regional imbalances in labor supply and demand. This report describes the U.S. experience with both unassisted and Government-assisted worker relocation. It examines the applicability of this experience to the current dislocated worker problem, as well. In addition, the report evaluates the feasibility of establishing a nationwide worker relocation program.
