An extensive discussion of considerations for fire protection in the LLL mirror fusion test facility (MFTF) is presented. Because of the large volume and high bays of the building, sufficient data on fire detection is unavailable. Results of fire detection tests using controlled fire sources in the building are presented. Extensive data concerning the behavior of the building atmosphere are included. Candidate fire detection instrumentation and extinguishing systems for use in the building are briefly reviewed. (RME)

The Lawrence Livermore Laboratory Shiva laser-target interaction facility is designed for experiments at 20 to 30 terawatts. At this power level there will be larger fluxes of neutrons, x-rays, electrons and ions than have been previously measured. The measurements of energy converted into the various reaction products is crucial both in target design and performance analysis of the actual experiment. The total energy absorbed is measured by a box calorimeter surrounding the target except for beam input holes. This measurement prevents the use of other diagnostics, so for normal operation an energy balance module was designed for location on ports on the Shiva target chamber. This module monitors the energy in scattered light at 10640 A and 5320 A or 7118 A. It also contains a faraday cup and plasma and x-ray calorimeters. The distribution of energy in scattered light, plasma and x-rays will be mapped by 58 such modules.

In the laser fusion program at Lawrence Livermore Laboratory, no target experiment is complete unless it is complemented by careful measurements of the laser pulse that irradiates the target. For this purpose, an incident beam diagnostics (IBD) package has been designed for the Shiva laser. The package will furnish data on items such as the total energy and the focusable energy out of the laser chain, and the spatial and temporal energy and power distribution at the target plane. Understanding laser-plasma interactions requires knowledge of the amount of 1.06 ..mu..m light energy that is scattered in various directions from the target. The light energy that is scattered toward the beam focusing lens is analyzed by a reflected beam diagnostic (RBD) package containing a calorimeter, a multiple image camera and a TV camera. This paper describes the detailed design and operation of the IBD and RBD packages as tools to align spatial filters and targets, as well as to diagnose the laser beams and target reflectivity.

A constitutive model for a rock equation of state was developed in HEMP and CEL-HEMP computer codes. The model includes the mechanical and thermal properties of soil, such as elasticity, pore closure, compaction, and vaporization. Three test problems were computed using the equation of state: ground motion following the LATIR event, impact vaporization of preheated plates, and surface motion produced from exploding a 3.7-kg(10-lb) charge at a depth of 6.5 m. Agreement between our computations from the model and actual measurements is remarkably close.

This report was prepared at the request of the Nuclear Regulatory Commission as a part of a license review of the nuclear fuel reprocessing plant operated by Nuclear Fuel Services, Inc., at West Valley, N.Y. The report discusses the approach used by the Lawrence Livermore Laboratory in performing an independent seismic analysis of the facility. It includes a description of the facility, our modeling and analysis techniques, failure criteria, results, and conclusions. Two modes of failure are identified and their consequences discussed.

Inertial confinement fusion (ICF) designs are considered which may have very high gains (approximately 1000) and low power requirements (<100 TW) for input energies of approximately one megajoule.

Process engineering designs, major equipment and plant facilities to be utilized in commercial nuclear waste preparation and vitrification in the 324 Radiochemical Engineering Building are reviewed with regard to accident potential and consequences. This Safety Analysis Report Supplement compares calculated environmental doses anticipated from the Commercial Nuclear Waste Vitrification Project (CNWVP) routine operations with the average doses from past waste management operations conducted at the Hanford Project and finds them to be significantly less. The calculated CNWVP environmental doses are found to be far below presently applicable ERDA standards and standards proposed by the EPA for nuclear power operations. (DLC)

The attainment of low-adiabat compression to high final state density is essential for achieving high gain thermonuclear micro-implosions. Using 1- and 2-dimensional numerical simulations with LASNEX, the target performance which can be expected and the limitations imposed by absorption heating, and transport for targets designed to reach 100 x liquid DT density (20g/cm/sup 3/) are discussed. The requirements imposed by the need for low preheat, adequate implosion symmetry, and the behavior of fluid instabilities are discussed for these recent target designs. Methods for diagnosis of density are discussed.

The OF-2 irradiation experiment was designed and built to test candidate High-Temperature Gas-Cooled Reactor (HTGR) fuel and fuel-rod matrix designs. The capsule was designed with two separate specimen cells, allowing for independent temperature control as well as independent fission gas release measurements. The OF-2 capsule is presently operating at the Oak Ridge Research Reactor (ORR). Initial fuel rod linear heat rates are between 16.4 and 23.0 kW/m (5 and 7 kW/ft) and fuel centerline temperatures are approximately 1150 and 1350/sup 0/C. Plans are to operate the capsule for nine ORR cycles to accumulate a maximum damage fluence of 9 x 10/sup 21/ neutrons/cm/sup 2/ (E > 0.18 MeV).

The report discusses the current status of liquid-metal fast breeder reactor (LMFBR) development and one of the principal safety issues, a hypothetical core-disruptive accident (HCDA). Bibliographic information on worldwide LMFBRs relative to the development of the breeder reactor as a safe source of nuclear power is presented for the period 1972 through 1974. The bibliography consists of approximately 1380 abstracts covering research and development and operating experiences leading up to the present design practices that are necessary for the licensing of breeder reactors. Key-word, author, and permuted-title indexes are included.

An energy flow diagram for the U.S. for 1976 is presented, and one for 1975 is included for comparison. Some significant differences between 1975 and 1976 are: total energy use increased 4.8 percent, almost reaching the record use of 1973; oil imports increased significantly to 15.5 quads, more than 20 percent above 1975, and almost 44 percent of our total oil use; coal and natural gas remained more or less constant; by the author's reckoning, the industrial sector was unique in that its energy use decreased somewhat due to conservation efforts; delivered nuclear power increased by 10.9 percent and a trend toward electrification continued with distributed electrical energy increasing by 6.1 percent.

This report is intended as a ''quick-look'' report summarizing the experimental results obtained from pressure suppression experiment numbers 2.1, 2.2, and 2.3 that were performed on the Lawrence Livermore Laboratory's 1/5-scale boiling water reactor (BWR) Mark I pressure suppression experimental facility on April 26, 1977. A brief description of the general nature of the tests and a summary of the actual tests that were performed are given.

An integrating sphere technique was used for the measurement of the total and specular reflectance of vacuum-evaporated aluminum films. The appearance of the surface to the naked eye was relatively insensitive to the total reflectance, but was very closely related to the fraction of reflected light that was specularly reflected. Milky or cloudy-appearing aluminum films had a low specular reflectance while mirror-like films had a high specular reflectance. Surface specular reflectance was in turn closely related to film microtopography; roughening features such as hillocks substantially reduced film shininess and hence specular reflectance. Although no extensive study to relate reflectance to deposition parameters was undertaken, specular reflectance was found to be very sensitive to chamber pressure during evaporation. Two alternate techniques for surface appearance measurements were evaluated and correlated with the integrating sphere method; these techniques yielded relative assessments of film shininess that corresponded well with visual appearance and integrating sphere results.

The study of Rydberg spectra and ionization thresholds of ten lanthanides using several variations of time-resolved resonant multistep techniques is reported. The ionization limits for the lanthanides determined in this way show a systematic dependence on atomic number. A physical model explaining these results is presented. 16 references. (JFP)

The Shiva laser system is part of a new 20 terawatt laser facility at Lawrence Livermore Laboratory. The system contains more than $5,000,000 worth of optics. This paper discusses the various optical components, typical component quantities and specification, and the problem of laser damage to components.

Electrostatic instabilities occurring in mirror-confined ion velocity-distributions have been thoroughly investigated. The electromagnetic instability of greatest concern is the Alfven-ion-cyclotron (AIC) mode. In this work we investigate both convective and absolute growth, both in homogeneous plasma and in finite machines, for a variety of ion velocity-distributions. Good agreement is found with the results from the particle simulation code ''Superlayer''. Quasilinear effects are outlined and a rough criterion found for the importance of Dupree-type broadening.

The differential equation and boundary conditions that describe steady state heat transfer in an Oak Ridge Research Reactor (ORR) irradiation capsule have been determined. The finite difference equations needed to obtain a numerical solution to the heat transfer problem were developed and an algorithm for the solution of these equations was specified. Analytical solutions for the second order partial differential equation with non-linear boundary conditions describing heat transfer in the problem were attempted. Various simplifying assumptions were not successful.

The Diablo Canyon Nuclear Power Plant, located on the central California coast, is nearing completion. Recent geologic and seismological investigations have indicated that the nearby Hosgri fault may be part of a major fault system. If so, the original Design Basis Earthquake (DBE) may be inadequate for Diablo Canyon. Therefore, several factors that could significantly affect the design response spectra for the site were examined. It was found that, because of the area's geology, significant site effects could occur that would reduce ground motion; possible soil-structure interaction would also reduce the seismic motion at the basemat of the main structure as compared to the free-field motion. Studies of wave-passage effects have shown that they are complicated and cannot be easily predicted. It is concluded that an increased-magnitude DBE should have little effect on the reactor design if the increase is caused by increased stress drop rather than greater fault rupture length.

Ultrafiltration media with and without the assistance of bone char filters were evaluated to determine their effectiveness in removing radionuclides from contaminated solutions. Precipitants, resin, adsorbents, and inorganic adsorbents were studied to determine their effectiveness in decontaminating solutions. A study of the effects of radiation on ultrafiltration media was initiated. An ultrafiltration media pilot plant was ordered and is being installed.

The alloy JBK-75, an age-hardenable austenitic stainless steel, is similar to commercial A-286, but has certain chemistry modifications to improve weldability and hydrogen compatibility. The principal changes are an increase in nickel and a decrease in manganese with lower limits on carbon, phosphorus, sulfur, silicon, and boron. In this study, the effects of solutionizing time and temperature, quench rate, cold working, and the effects of cold working on precipitation kinetics were examined. Findings show that the solutionizing temperature has a moderate effect on the as-quenched hardness, while times greater than that required for solutionizing do not significantly affect hardness. Quench rate was found to have a small effect on as-quenched hardness, however, hardness gradients did not develop in small bars. It was found that JBK-75 can be significantly strengthened by cold working. Cold working alone produced hardness increases from Rockwell-A 49 to R/sub A/ 68. A recovery-related hardness change was noted on heat treating at 300 and 400/sup 0/C for both as-quenched and as-worked JBK-75. Significant age-hardening was observed at temperatures as low as 500/sup 0/C for as-worked metal. Aging at 600/sup 0/C resulted in maximum hardness in the 75 percent worked sample at about 6 hours (R/sub A/ 73.5) …
