Mica-based Composite Compressive Seals for SOFC

Description: One of the critical challenges facing planar solid oxide fuel cell (SOFC) technology is the need for reliable sealing technology. Seals are required for long-term stability and integrity in the high temperature SOFC environment during normal and transient operations. Several different approaches for sealing SOFC stacks are under development, including glass or glass-ceramic seals, metallic brazes, and compressive seals. Compressive seals potentially offer a significant and unique advantage over… more

Tank 41H Post-Dissolution Saltcake Core and Supernate SampleAnalysis

Description: This report provides analyses of the samples from Tank 41H. The characterization also includes supernate samples pulled from the surface (347 inch) and 250 inch levels of the salt supernate. The three saltcake samples (HTF-E-03-145, 146, and 147) were filled to nearly their capacity with saltcake and free liquid, with an average saltcake bulk density of 2.06 g/cm3. The undrained saltcake from the bottom of the middle sample (HTF-E-03-146) had a water content of 4.1 percentage weight, a 137Cs ac… more

Tank 38H Saltcake Core and Supernate Sample Analysis

Description: This report provides details of the characterization of Tank 38H saltcake and supernate samples pulled in September 2003. The core sample HTF-E-03-114 contained approximately 4 inches of saltcake, which was soupy and brown with white chunks, and contained less than 15 mL of cloudy free liquid. The undrained bulk saltcake had a water content of 16.8 percentage weight and a bulk density that was approximately 1.94 g/cm3 at full saturation. The 137Cs activity of the bulk saltcake in sample HTF-E-0… more

Tanks 3F and 2F Saltcake Core and Supernate Sample Analysis

Description: In support of Low-Curie Salt (LCS) process validation at the Savannah River Site (SRS), Liquid Waste Disposition (LWD) has undertaken a program of tank waste characterization, including salt sampling. As part of this initiative, they sampled the surface of the saltcake in Tank 3F and Tank 2F using approximately 12-inch long sample tubes. A series of three saltcake samples were taken of the upper crust in Tank 3F and a single saltcake sample was taken from the bottom of a liquid-filled well in T… more

Prediction of External Corrosion for Steel Cylinders--2004 Report

Description: Depleted uranium hexafluoride (UF{sub 6}) is stored in over 60,000 steel cylinders at the East Tennessee Technology Park (ETTP) in Oak Ridge, Tennessee, at the Paducah Gaseous Diffusion Plant (PGDP) in Paducah, Kentucky, and at the Portsmouth Gaseous Diffusion Plant (PORTS) in Portsmouth, Ohio. The cylinders range in age from 4 to 53 years. Although when new the cylinders had wall thicknesses specified to within manufacturing tolerances, over the years corrosion has reduced their actual wall th… more
