Design and Fabrication of the EBR-II Environmental Instrumented Subassembly : Test XX07
The EBR-II environmental instrumented subassembly (EISA), or Test XX07, was designed, fabricated, and irradiated to provide in-core measurements of irradiation conditions. This subassembly contained 57 elements with uranium metal-5 wt.% fissium fuel and four non-fueled elements. It was instrumented with two permanent-magnet flowmeters, 13 coolant thermocouples at various axial and radial locations, 10fuel-centerline thermocouples, and two self-powered detectors. The subassembly was irradiated in EBR-II for about 11,600 MWd (-186 days), reaching a peak burnup of about 2.9 at.% During its residence in the reactor, XX07 provided in-core measurements of flow, temperature and flux levels under both steady-state and dynamic conditions.
Design, Construction, and Initial Operation of the ANL Research Salt-Gradient Solar Pond
The design consideration of a 1/4 acre research salt-gradient solar pond is described. Experience learned during the construction of the solar pond is presented. Initial operation of the pond indicates that the construction of the pond is sound and no leakage has occurred. The pond began to warm up during March of 1981. The maximum pond temperature reached 63 C at the end of July and it is still rising. All signs indicate that the operation of the well instrumented pond will be a success and the performance of the pond will be as expected, if not better.
EBR-II Environmental Instrumented Subassembly XX08 : Engineering and Assembly
Subassembly XX08 is a fueled and instrumented subassembly designed primarily for an ongoing program to investigate the thermal-hydraulic core environment within EBR-II under normal and off-normal plant operating conditions. XX08 contains 58-xenon-tagged, EBR-II Mark-II driver-fuel elements. The Mark-II fuel is expected to provide XX08 with an irradiation lifetime three times as great as that attained with its predecessor, XX07, i.e., a 9 versus 2.9% burnup. A burnup of 9 at.% is equivalent to about 29,000 MWt dyays of EBR-II reactor operation, which corresponds to 11 reactor runs at 2700 MWd per run.
Final Report on Test L4, a Loss-of-Flow Experiment
The behavior of FTR-type, mixed-oxide, pre-irradiated "high-power-structure" fuel during a simulation of an FTR loss-of-flow accident was studied in the Mark-IIA integral TREAT loop. Analysis of the data leads to a postulated scenario (sequence and timing) of events in this test. This scenario is presented, together with the calculated timing of events obtained by use of SAS code.

High Temperature Work in Igneous Fusion and Ebullition, Chiefly in Relation to Pressure
Preface: In the following bulletin I have brought together the more important results of experiments in high temperatures, made since the publication of my bulletin on the thermoelectric measurement of high temperatures.' Chapter I, in addition to pointing out certain inherent relations between metallic vapor tensions, has a direct bearing on pyrometry. Chapters 11 and ii are of geological importance, and the work was done for Mr. Clarence King. Chapter ii shows that in case of the igneous fusion of basic magma, the passage from liquid to solid is one of contraction, and measures the difference of specific volumes at the solidifying temperature. Chapter iii contains a full account of the thermal capacity of the same rock under the same conditions, and by aid of Chapter it leads to a numerical value for the relation of melting point to pressure, for silicates.
