Development of biological coal gasification (MicGAS Process)

This report describes progress on three fronts of the project. First in studies to elucidate optimal growing conditions for the consortia of coal degraders employed indicates that best growth occurs with 0. 2% w/v Shefton T. Secondly in comparing the biodegradative properties of the coal degraders, isolates identified as Mic-1 and Mic-4 were the best performers. And lastly bioreactors studies in batch mode are related.

Corrosion tests of DWPF recycle solution

Coupon immersion tests were performed on ASTM A537, Class 1 carbon steel in simulated Defense Waste Processing Facility recycle solutions at 93 [plus minus] 2[degree]C, in an effort to reproduce the results of earlier tests in which hard, shock-sensitive deposits were found. There was no evidence of pitting corrosion on the coupons exposed to solutions containing 0.5 M hydroxide and 2000 ppm (0.043 M) nitrite. Liquid mercury and small solid deposits were found on the specimens' immersed surface… more

Thermo-mechanical optimization of photon shutter 1 for APS front ends

Photon shutter 1 (PS1) is one of the most critical elements on the front end of the beamlines at the Advanced Photon Source (APS) now under construction at Argonne National Laboratory (ANL). The PS1 uses an enhanced heat transfer tube developed at ANL. Due to large thermal loads on these components, inclined geometry is used in the design to spread the footprint of the x-ray beam. Even then, thermal loads are very critical. To address the thermal and thermo-mechanical issues, analytical studies… more
