Development and testing of shingle-type solar cell modules. Quarterly report No. 2

Description: The details of a shingle module design which produces in excess of 97 watts/m/sup 2/ of module area at 1 kW/m/sup 2/ insolation and at 60/sup 0/C are reported. This selected design employs a tempered glass coverplate to provide the primary solar cell structural support. The use of the B.F. Goodrich FLEXSEAL roofing system as the outer skin of the shingle substrate provides a high confidence of achieving the 15 year service life goal. The fabrication and testing of a preproduction module of this… more

Literature review of the saturation state of seawater with respect to calcium carbonate and its possible significance for scale formation on OTEC heat exchangers

Description: An investigation of available data on the saturation state of seawater with respect to calcium carbonate and its possible significance for scale formation on Ocean Thermal Energy Conversion (OTEC) heat exchangers has been carried out. Pertinent oceanographic data is lacking at or near potential OTEC sites for the calculation of the degree of saturation of seawater with respect to calcium carbonate. Consequently, only ''extrapolated'' saturation values can be used. These indicate that near surfa… more

Utilization of shale oil as a feedstock for steam pyrolysis and petrochemical intermediate production. Quarterly technical progress report, June-August 1978

Description: During the past quarter, 5 runs were made on a number of hydrotreated samples including a mildly hydrotreated simulated in-situ (1.35% N) and two moderately hydrotreated Tosco II (0.82% N and 1.55% N) distillates. The results are, in general, consistent with previous results which indicated an increase in olefins yield as the severity of hydrogenation increased. The olefins yields for the simulated in-situ oil were greater than those for the Tosco II oil for oil hydrogenated to comparable sever… more

Test results: direct contact heat exchanger for Biophase diesel bottoming system

Description: A subscale, direct contact heat exchanger (1-ft dia packed column) was built and operated under conditions applicable to the Biphase diesel bottoming cycle. Special probes for measuring gas and liquid temperatures and for measuring gas-phase compositions were designed and installed in the exchanger. The data obtained are unique in that they indicate both the extent of evaporation and condensation zones within the exchanger and the effect that those mass transport mechanisms have upon heat excha… more

TRU waste cyclone drum incinerator and treatment system: January--March 1978

Description: The cyclone incinerator was operated throughout the past quarter, generating additional data on system characteristics, equipment life expectancies, and by-product generation. Several changes in the incinerator system are in various stages of completion. The lid assembly, secondary chamber, and expansion unit for the new exhaust equipment are nearly ready for installation. A new heat exchanger has been installed in the scrubber system. An ash handling system has been designed for possible futur… more

Experimental determination of kerma factors at E/sub n/ approx. = 15 MeV

Description: Experimental values for the kerma per unit fluence at the neutron energy, E/sub n/ = 15 MeV, have been determined for graphite, Mg, and Fe. Ion chambers of small size with walls of these materials were employed, and were filled with a variety of gases--N/sub 2/, CO/sub 2/, Ne, Ar, Kr, and Xe. A calibrated neutron source was employed, allowing a straightforward determination of the kerma per unit fluence.

Combining evidence from several samples for testing goodness-of-fit to a location-scale family. Technical report No. 15

Description: Consider the problem of testing goodness-of-fit to a specified location-scale family when evidence is to be combined from several independent samples, from populations with possibly different location and scale parameters. The procedure studied is that of computing standardized residuals from each sample and then combining these into one set to be treated essentially as though they came from one sample. It is shown that the limiting distribution of any location-scale invariant goodness-of-fit s… more

Structural analyses of the fuel receiving station pool at the Nuclear Fuel Service reprocessing plant, West Valley, New York

Description: The FRS is a pool structure and enclosing building constructed in 1966 for storing spent nuclear fuel. The enclosing building was not analyzed. The pool structure's responses to operating loads, seismic excitation, and an accidentally dropped cask were determined. Locations in the FRS pool were identified where structural strength would be exceeded in the event of an earthquake of 0.2 g maximum ground acceleration or an accident in which a cask dropped from the maximum height of the crane hook … more

Core-power and decay-time limits for disabled automatic-actuation of LOFT ECCS

Description: 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. LTR 113-47 has shown that the LOFT ECCS can be safely bypassed or disabled when the total core power does not exceed 25 kW. A modified pol… more

Volume reduction system for solid and liquid TRU waste from the nuclear fuel cycle: January--March 1978

Description: The laboratory cyclone incinerator, which started operation in January, 1978, has been developed to study the effects of burning feed containing radionuclides other than /sup 238/Pu. These isotopes must be removed from the off-gas during incineration. Preliminary data from early runs show that the combustion efficiency of the incinerator can still be improved. Controlled experiments were conducted on the pressed ash-cement pellet matrix to define compressive strength, mechanical stability, dens… more

DYNSYL: a general-purpose dynamic simulator for chemical processes

Description: Lawrence Livermore Laboratory is conducting a safeguards program for the Nuclear Regulatory Commission. The goal of the Material Control Project of this program is to evaluate material control and accounting (MCA) methods in plants that handle special nuclear material (SNM). To this end we designed and implemented the dynamic chemical plant simulation program DYNSYL. This program can be used to generate process data or to provide estimates of process performance; it simulates both steady-state … more

Preliminary definition of Barstow standard cloud model

Description: The motion of cloud shadows across a collector field for a central receiver solar power plant can affect the design of such a facility. Cloud models were developed to be used for basis of design in technology areas. The first effect, that of the temperature gradient, is simulated by postulating the worst case cloud situation. The cyclic effects require realistic cloud shadow time histories for simulation. Cloud shadow models were developed to determine probable cloud type, the cloud area and sh… more

LOFT reactor vessel head instrument penetration, flange thermal analysis

Description: A redesign of the LOFT instrument penetration necessitated a reanalysis of the thermal conditions existing in the nozzle and flange during a Loss of Coolant Experiment (LOCE). The maximum temperature gradient existing in the instrument flange will be used to determine the thermal stresses and maximum number of allowable cycles for the instrument flange. Based upon the specification and thermal conditions predicted by RELAP4/MOD5, the maximum temperature gradient through the flange will not exce… more

Casting large beryllium ingots

Description: Beryllium casting is a relatively new technology with the successful cast of large ingots being developed during the last decade. In 1961, Rocky Flats initiated a beryllium ingot-sheet fabrication process that included the development of new techniques to consistently cast large sound beryllium ingots. This report reviews the casting technology that was developed to cast these beryllium ingots on a production basis along with some of the remaining technical problems requiring additional develop… more
