Two successful shock tube experiments were recently performed at the Lawrence Livermore Laboratory. The experiments simulated the high enthalpy flow conditions that might arise in the nuclear blast encounter of a tunnel-based missile. The experiments, using a modified Voitenko high explosive generator, produced megabar pressure conditions at the inlet of the 2 cm-diameter air-filled shock tubes. Computer calculations have been done to model the 10/sup 5/-fold increase in air pressure in the Voitenko generator. These calculations are necessary to describe the source for the experiments and to permit better interpretation of the experimental data. A detailed understanding of the phenomenology of the compressor is also essential for optimization of future experiments, especially those involving scaling up to larger size shock tubes. An arbitrary Lagrange-Eulerian computer code was selected to calculate the late-time high explosive driven motion of a steel plate into the bell shaped compressor section. It was found that ordinary Lagrangian and Eulerian codes had difficulty in properly treating the steel-air interfaces, whereas an arbitrary Lagrange-Eulerian code was capable of modeling the complex flow of air past the steel interfaces in the compressor region. Using an improved equation of state for air, excellent agreement has been obtained in the …

The objective of this document is to outline the test plan for the KIPS Technology Verification Program. This test plan is inclusive of component simulating (rig) testing, component testing and system testing. Rig testing will prove concept feasibility, measure basic performance and to develop the hardware necessary prior to initiation of GDS component part manufacture. Component testing will measure basic performance and verify component integrity prior to GDS assembly. The GDS system testing will: simulate the flight system operation; determine the life limiting components; measure performance and relate to potential system lifetime; demonstrate 18+% DC generating efficiency; and perform a 5000 h endurance test with final configuration hardware.

During this program, the use of energy storage in conventional appliances to save energy was evaluated. Fuel-fired appliances, electric appliances, and utility load leveling by energy storage on the customer's side of the meter were considered. For each of the appliances treated, various energy-storage techniques were evaluated by estimating the energy savings and the cost of the required storage system. An estimate of the commercial feasibility of each system was made based on the years necessary to pay back the cost of the storage system. In addition, when alternate approaches could be used to improve the efficiency of the appliance without energy storage, the costs of these methods were considered in the evaluation. The analyses found that the most-promising applications involved the use of point-of-use thermal energy storage for electric-utility load-leveling. However, although substantial utility operating cost savings can be achieved, there may be little or no actual energy saving when all losses are considered. For applications other than load-leveling, energy savings were too small to pay back the added cost of the storage system in an acceptable time.

The results are presented of stress analysis and evaluation of the drag-disc turbine transducer (DTT) shroud and cover welds used in the Loss-of-Fluid Test (LOFT) facility. The analysis concerns LOFT DTTs currently installed and/or planned for use in future experiments by LOFT Experimental Measurements Branch personnel. Thermal/hydraulic conditions for Experiments L1-5 and L2-4 (for all nuclear tests) were used to predict the loads experienced by the various shroud and cover welds. The results of this analysis include minimum fatigue life for all subject welds, and Applied Mechanics Branch recommendations for improving the structural integrity of critically stressed welds.

The proposed weld modifications for LOFT DTT's planned for future use in nuclear blowdown experiments are described. The attached calculations provide the basis for the statements concerning weld modifications.

The Emergency Core Cooling System (ECCS) for the LOFT reactor may need to be disabled for modifications or repairs of hardware or instrumentation or for component testing during periods when the reactor system is hot and pressurized, or it may be desirable to enable the ECCS to be disabled without the necessity of cooling down and depressurizing the reactor. A policy involves disabling the automatic-actuation of the LOFT ECCS, but still retaining the manual actuation capability. Disabling of the automatic actuation can be safely utilized, without subjecting the fuel cladding to unacceptable temperatures, when the LOFT power decays to 33 kW; this power level permits a maximum delay of 20 minutes following a LOCA for the manual actuation of ECCS. For the operating power of the L2-2 Experiment, the required decay-periods (with operating periods of 40 and 2000 hours) are about 21 and 389 hours, respectively. With operating periods of 40 and 2000 hours at Core-I full power, the required decay-periods are about 42 and 973 hours, respectively. After these decay periods the automatic actuation of the LOFT ECCS can be disabled assuming a maximum delay of 20 minutes following a LOCA for the manual actuation of ECCS. The automatic …
