Mark I 1/5-scale boiling water reactor pressure suppression experiment facility report
An accurate Mark I /sup 1///sub 5/-scale, boiling water reactor (BWR), pressure suppression facility was designed and constructed at Lawrence Livermore Laboratory (LLL) in 11 months. Twenty-seven air tests using the facility are described. Cost was minimized by utilizing equipment borrowed from other LLL programs. The total value of borrowed equipment exceeded the program's budget of $2,020,000. Substantial flexibility in the facility was used to permit independent variation in the drywell pressure-time history, initial pressure in the drywell and toroidal wetwells, initial toroidal wetwell water level and downcomer length, vent line flow resistance, and vent line flow asymmetry. The two- and three-dimensional sectors of the toroidal wetwell provided significant data.

Quadrupole mass-filter sensitivities of H/sub 2/, HD, D/sub 2/, and T/sub 2/, and the kinetics of. beta. -particle induced exchange between H/sub 2/, D/sub 2/, and T/sub 2/ at 25. 4/sup 0/C
We have constructed a quadrupole-mass filter system to measure the equilibrium constants and rates of reaction of the ..beta..-particle-induced exchanges between H/sub 2/, D/sub 2/, and T/sub 2/ at cryogenic temperatures. Even with careful calibration experiments at 25.4/sup 0/C, we could not completely remove the mass discrimination inherent in our method. We estimate the accuracy of our mixture analyses to be +-2.2% in the D/sub 2/-DT-T/sub 2/ system, and +-9% in the H/sub 2/-HT-T/sub 2/ system. Preliminary kinetic experiments showed that the time to reach equilibrium in the exchange H/sub 2/ + T/sub 2/ = 2HT is 7 to 14 h. The equivalent time interval in the exchange D/sub 2/ + T/sub 2/ = 2DT is 3 to 7 h. This measured isotope effect of two can be used to predict the rates of the DT exchange from the HT rates in the literature.

Preliminary report on Battelle Northwest Liquid Level Probes (LLP)
The Battelle Northwest Liquid Level Probe was evaluated for possible use in the LOFT Blowdown Suppression Tank. The results from the test indicate that the probe will measure the liquid level to +-/sup 1///sub 4/ inch, over a range of 50 inches. The next step is to test the functionability of the probe under simulated LOFT-Blowdown Suppression Tank operating conditions.

Near Term Hybrid Passenger Vehicle Development Program. Phase I, Final report. Appendix B: trade-off studies. Volume I
Trade-off studies of Near Term Hybrid Vehicle (NTHV) design elements were performed to identify the most promising design concept in terms of achievable petroleum savings. The activities in these studies are described. The results are presented as preliminary NTHV body design, expected fuel consumption as a function of vehicle speed, engine requirements, battery requirements, and vehicle reliability and cost. (LCL)

Surge-damping vacuum valve
A valve for damping out flow surges in a vacuum system is described. The surge-damping mechanism consists of a slotted, spring-loaded disk adjacent to the valve's vacuum port (the flow passage to the vacuum roughing pump). Under flow surge conditions, the differential pressure forces the disk into a sealing engagement with the vacuum port, thereby restricting the gas flow path to narrow slots in the disk's periphery. The increased flow damps out the flow surge. When pressure is equalized on both sides of the valve, the spring load moves the disk away from the port to restore full flow conductance through the valve.

Defect states in plasma-deposited a-Si:H. Technical progress report, August-October 1979
Raman and ESR measurements were used to study the atomic bonding and defect concentrations. Features are identified in the Raman spectra which can be attributed to configurations containing Si-Si, Si-As and As-As bonds. Features due to all three of these configurations were found to simultaneously exist, thus excluding a chemically ordered model of the bonding. However, the composition dependences of the features do not follow exactly a random bonding model either. The H bonding configurations were reflected in features at approx.2000 cm/sup -1/ in the Raman spectra. It was found that the H bonding changed dramatically in the As doping to 5% As alloying region. The ESR measurements indicated a low level of singly occupied defect states in all the samples studied.

Systematics of neutron-induced fission cross sections over the energy range 0. 1 through 15 MeV, and at 0. 0253 eV
Recent studies have shown straightforward systematic behavior as a function of constant proton and neutron number for neutron-induced fission cross sections of the actinide elements in the incident-neutron energy range 3 to 5 MeV. In this report, the second in a series, fission cross-section values are studied over the MeV incident-neutron energy range, and at 0.0253 eV. Fission-barrier heights and neutron-binding energies are correlated by constant proton and neutron number; however, these systematic behaviors alone do not explain the trends observed in the fission cross-section values.

Fracture mechanics evaluation of LOFT lower plenum injection nozzle
An analysis to establish whether or not a leak-before-break concept would apply to the LOFT lower plenum injection nozzle is described. The analysis encompassed the structure from the inlet side of valve V-2170 to the lower plenum nozzle-to-reactor vessel weld on the left side of the emergency core cooling system (ECCS). The defect that was assumed to exist was of such a size that the probability of its being missed by the applicable inspection technique was near zero. The Inconel 600 nozzle forging with an initial assumed defect size of 0.64 cm (0.25 in.) deep would behave as follows: (1) the axially oriented defect would result in leak before rupture (the number of cycles to rupture was 11,000), (2) the circumferentially oriented defect would result in a rupture before leak. The number of cycles to failure would be in excess of 14,000. Based on the conservative assumption that the thermal stresses were membrane stresses as opposed to a bending stress, the following were found. For the Inconel 82 weld metal (thickness of 1.3 cm (0.53 in.)) and AISI 316 SST valve body, with an initial assumed defect of 0.25 cm (0.1 in.), the crack would grow through the thickness in …

Energy planning and management in developing countries: thoughts concerning a conceptual framework
The unique characteristics of the energy situation in developing countries imposes a unique set of requirements on analytical techniques used for energy planning. The urgency of the situation requires the rapid development and use of simplified models which make maximum use of available data but which can reflect the international energy context. Those techniques must also be able to deal with central energy/development issues such as energy equity or the energy implication of social equity policies, centralized vs. decentralized development, and urbanization.
