Application of Solar Energy to Air Conditioning Systems
The results of a survey of solar energy system applications of air conditioning are summarized. Techniques discussed are both solar powered (absorption cycle and the heat engine/ Rankine cycle) and solar related (heat pump). Brief descriptions of the physical implications of various air conditioning techniques, discussions of status, proposed technological improvements, methods of utilization and simulation models are presented, along with an extensive bibliography of related literature.

Some sensitivity analyses of an hourly soil-plant water relations model
Nineteen parameters representing landscape, plant, and soil characteristics were examined for their influence on midday plant water relations, daily fluxes and monthly water balance components predicted by a soil-plant-water relations model having hourly resolution. A standard set of parameters was chosen to represent a hardwood forest on ridge top soil in the Oak Ridge, Tennessee, area during a representative summer month (July). Each parameter was varied through a range with all other parameters held at the standard value. The results of the study showed that the model was sensitive to nine plant parameters in noon, daily and monthly results. The ten other parameters had partial or no influence on the simulations. Two leaf characteristics and two landscape properties cause the model to be sensitive in midday values but less sensitive in monthly results due to the negative feedback aspects of the model. Five parameters had almost no influence on the model results in the case examined. The canopy interception parameter had almost no influence on the model results on sunny days, but was a significant component of the monthly water balance. The study highlighted the importance of the root and stem resistances to water flow in influencing plant water status …

Interaction cross section of C/sub s//sup +/ ions
Some estimates of the shape of C/sub s/ ion and C/sub s/ atom interaction potentials suggest that the C/sup +//sub s/ + C/sup +//sub s/ charge transfer cross section may be less than 10/sup -15/ cm/sup 2/.

Stemming options and their effect on containment
In more than 17 years of studying underground nuclear explosions, LLL has developed containment procedures that include a stemming plan. Stemming plans can be divided into either layered or continuous forms. There are marked differences between standards for these forms. The materials used in the continuous plan must meet more stringent specifications; as a consequence, they are more expensive. Both plans have been successful since the Baneberry Event. Both plans must meet the following requirements: provide a plug sufficient to match the overburden density of earth; contain radioactive gases at the lowest possible depth; minimize the generation of noncondensable gases (such as CO/sub 2/); minimize gas flow rates during the early post-detonation stages when cavity pressure is high; and be compatible with the experiment and its diagnostics. LLL experience in developing containment procedures is reviewed, and the reasons for the adoption of LLL's continuous stemming plan are reported. (LCL)

Onslow Bay Intrusion Study Hydrographic Observations During Current Meter Servicing Cruises in August, October, and December 1975. ORBIS, I, III and IV. [Atlantic Coastal Waters Off Georgia]
Data are presented from a preliminary analysis of chemical/physical data obtained during three current meter servicing cruises in Onslow Bay off the coast of Georgia, in August, October, and December 1975 aboard the R/V ADVANCE II. These cruises were made as part of an ERDA sponsored study investigating the shelf processes effecting the distribution of nutrients in the South Atlantic Bight. The objective of these cruises was to collect temperature and chemical data to correlate with the data recorded by current meters and thermographs which had already been deployed or which were about to be deployed at two locations in the study area. No attempt will be made at this time however to correlate the data presented to these related records.

Atmospheric impacts of evaporative cooling systems
The report summarizes available information on the effects of various power plant cooling systems on the atmosphere. While evaporative cooling systems sharply reduce the biological impacts of thermal discharges in water bodies, they create (at least, for heat-release rates comparable to those of two-unit nuclear generating stations) atmospheric changes. For an isolated site such as required for a nuclear power plant, these changes are rather small and local, and usually environmentally acceptable. However, one cannot say with certainty that these effects will remain small as the number of reactors on a given site increases. There must exist a critical heat load for a specific site which, if exceeded, can create its own weather patterns, and thus create inadvertent weather changes such as rain and snow, severe thunderstorms, and tornadoes. Because proven mathematical models are not available, it is not now possible to forecast precisely the extent and frequency of the atmospheric effects of a particular heat-dissipation system at a particular site. Field research on many aspects of cooling system operation is needed in order to document and quantify the actual atmospheric changes caused by a given cooling system and to provide the data needed to develop and verify mathematical and …

Effects of sleeve blockages on air velocity distributions in an unheated 7 x 7 rod bundle. [PWR]
An experimental study is described which was performed to investigate the turbulent air velocity distributions near postulated sleeve blockages in a model nuclear fuel rod bundle. The sleeve blockages were characteristic of fuel clad ''swelling'' or ''ballooning'' which might occur during loss-of-coolant accidents (LOCA) in pressurized water reactors. The study was conducted to provide air velocity distributions near postulated blockages, to compare the air results with data obtained in a prior water experiment, and to further evaluate the use of the COBRA computer program for predicting flow distributions in rod bundles containing partial flow blockages.

Monte Carlo model for a thick target T(D,n)/sup 4/ He neutron source
A brief description is given of a calculational model developed to simulate a T(D,n)/sup 4/ He neutron source which is anisotropic in energy and intensity. The model also provides a means for including the time dependency of the neutron source. Although the model has been applied specifically to the Lawrence Livermore Laboratory ICT accelerator, the technique is general and can be applied to any similar neutron source.

I. Cis-dichlorodiammineplatinum(II). Aquation equilibria and isotopic exchange of chloride ligands with free chloride and tetrachloroplatinate(II). II. The Szilard--Chalmers effect in solid-state systems containing the octa-. mu. /sub 3/-chloro-octahedro-hexamolybdenum(II) cluster
A titration technique was utilized to determine the equilibrium quotients for the first and second aquation steps of cis-Pt(NH/sub 3/)/sub 2/Cl/sub 2/. At 25.0/sup 0/C and an ionic strength of 0.318 M the first and second aquation equilibrium constants are: K/sub 1/ = 3.63 +- 0.22 x 10/sup -3/ M, ..delta..H/sub 1//sup 0/ = 3.4 kcal and K/sub 2/ = 1.11 +- 0.14 x 10/sup -4/ M, ..delta..H/sub 2//sup 0/ = 10 kcal. In the ternary system, cis-Pt(NH/sub 3/)/sub 2/Cl/sub 2/:PtCl/sub 4//sup 2 -/:Cl/sup -/, the kinetics of isotopic exchange of chlorine was investigated. In addition to the expected route of exchange via aquation, a direct exchange of chlorine ligands between cis-Pt(NH/sub 3/)/sub 2/Cl/sub 2/ and PtCl/sub 4//sup 2 -/ occurred which is described by the rate expression. Separation procedures were devised for partial resolution of component yields resulting from dissolving a neutron-irradiated sample of (H/sub 3/O)/sub 2/((Mo/sub 6/Cl/sub 8/)Cl/sub 6/) . 6H/sub 2/O in 1.5 N HCl. A recrystallization procedure was formulated to determine the retention of activity in the parent compound of molybdenum(II) chloride clusters after neutron irradiation. The retention found in an aqueous 1.5 N HCl solution containing 1 percent (H/sub 3/O)/sub 2/((Mo/sub 6/Cl/sub 8/)Cl/sub 6/) . …
