SCWR heat transfer deterioration phenomenon

AI Thread Summary
The discussion centers on the deterioration of heat transfer surfaces in coal-fired systems, specifically regarding waterside corrosion and its impact on thermal hydraulics. Participants express interest in the limited literature available on this topic, particularly concerning superheated and supercritical conditions. The conversation highlights the need for more experimental data and publications, especially regarding buoyancy forces and acceleration in both natural circulation and forced convection scenarios. The complexity of predicting corrosion onset and understanding the underlying phenomena is emphasized as a critical area for future research. Overall, there is a call for collaboration and further exploration of these issues in the scientific community.

Please describe the problem. Is one referring to deterioration of the heat transfer surfaces due to corrosion? In-core, ex-core surfaces, or both?

I believe their is a fair amount of literature with respect to waterside corrosion of metals in superheated and supercritical coal-fired systems.
 
The phenomenon is interesting from the thermal hydraulic point of view not corrosion but due to buoyancy forces or acceleration. There is not that much publications in fact and even less data on experiments.

Forced convection is more interesting. The nature of the phenomenon sure is of top interest but as I know it's said not to be understood by now. Then the prediction and onset. Experiments and calculation methodology etc.
 

Thread 'Energy Spectrum Attenuation'

Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
