Analysis of test data on ablation of SNAP 2/10A fuel, aluminum, and stainless steel in an arc-heated wind tunnel

Description: A series of arc-jet tests were performed for the purpose of investigating the behavior of SNAP 2/10A fuel in a simulated reentry environment. The data from the tests (motion pictures and transient temperature distributions) were analyzed and compared with computations which used an energy balance to describe the heating of the fuel to its melting temperature. The dissociation of hydrogen was assumed to occur as an isothermal, endothermic phase change. This concept neglects the kinetics of diffu… more

Thermal shield cooling tube surveillance: B, C, D, and K Reactors

Description: The top thermal shields of the Hanford reactors were formed by placing single layers of large cast iron blocks on the top of the graphite stacks. Accumulative distortion of the graphite stack is causing several inches of variation in the elevation of the originally level top thermal shields. The integrity of the top thermal shield cooling tubes is of concern because of the high axial and bending stresses they are subjected to from the shield variations in addition to the normal service conditio… more

Evaporation of Iron-, Nickel-, and Cobalt-Base Alloys at 760 to 980°C in High Vacuums

Description: Report issued by the Oak Ridge National Laboratory discussing the evaporation of alloys in high vacuums. As stated in the introduction, "the investigation encompasses measurements of the evaporation rates, identification of the evaporating elements, and correlation of these measurements to the alloy composition for specimens in both the polished and oxidized conditions" (p. 2). This report includes tables, illustrations, and photographs.

Production test IP-734, HAPO 309: High core temperature capsules in the KW Snout facility, Series 2

Description: The objective of the production test detailed in this report is to continue a program started under Production Test IP-690; the major change is an increase in sample enrichment. The higher enrichment is required to increase the portion of the fuel element core which is molten. This test will provide data to correlate maximum fuel temperature with post-irradiation microstructure, and data that are required to study the kinetics of fuel redistribution during the time interval between insertion of… more

Conoseal Bar-X Seal Tests

Description: On the NRX-A reactors the instrument ports are sealed by a Bar-X seal. Damage to the ports, which are part of the pressure vessel, required machining on the pressure vessel. A new design, using a Marman flanged piece to house the Bar-X seal port separate from the pressure vessel, was proposed. The test program was to determine the torque required to seal and the ability of each seal to hold during thermal shock.
