SUMMARY OF HRE-2 RUN 13 (INITIAL POWER OPERATION)
Abstract
The first power operation of the HRE-2, referred to as Run 13, occurred in February 1958. In five days of power operation, the maximum sustained power was 1.5 Mw and the total power generated was 4B Mw-hr. During the first part of the power operation, the fuel solution contained very little internal recombination catalyst. This part of the run was characterized by high concentrations of radiolytic gas and significant loss of reactivity at very low powers. After an addition of copper and acid, reactivity losses were observed only nt higher powers. Power operation was terminated after samples showed high nickel concentrations in the fuel solution, indicating a very high stainless steel corrosion rate. Subsequent subcritical operation ended because of power wiring insulation failures. (auth)

The Prototype Power Plant was built to demonstrate and learn the operation of a binary power cycle, and then serve as a test bed for pilot scale components, systems, and/or concepts that have the potential for enhancing the feasibility of power generation from a moderate temperature geothermal fluid resource. The operation to date of the prototype plant is summarized with primary emphasis on the automatic-run phase, during which the plant was operated over a five-month period with minimal operator surveillance.

EXAMINATION OF CORE ACCESS FLANGE SPECIMEN AND SCALES FROM HRE-2 AFTER RUN 16
Observations, weight data, and chemical analyses of scales on the core access flange and attached specimen assembly exposed in HRE-2 during reactor runs 15 and 16 are reported. The stheinless steel specimen showed a very small weight loss. All surfaces exposed to the reactor solution were covered with an unusual two-layer scale. (auth) -
THERMAL NEUTRON FLUX AT THE HRE-2 CORE WALL, DETERMINED FROM ZIRCALOY-2 INDUCED-ACTIVITY MEASUREMENTS DURING RUNS 13, 14, 16, 17, 18, 19, 20 AND 21
The thermal-neutron flux prevailing near the upper hole in the HRE-2 core wall was determined from measurements of the induced activity in a specimen cut from the edge of the hole. The specimen was removed following run 21 and was thus exposed to reactor neutrons during runs 13, 14, 16, 17, 18, 19, 20, and 21. The neutron flux, calculated for an average core power level of 2 Mw, was 2.8 x 10/sup 13/ neutrons/cm/sup 2//sec. The core wall area from which the specimen was removed was located approximately 16 in. from the core center. The flux is compared withmore »
