Dear Patricia,
1) No, this is not a homework.
2) Sorry to give you such lack of information, but this all I got at the moment.
3) All I know that the neutron flux is produced in a research reactor. I do not have information about the relative location of the neutron flux to the tube and the...
I have following details about the neutron flux:
Neutron fast flux (above 1MeV): 1,9*10^14 n/cm^2/s
Neutron fast flux (above 0,1MeV): 4*10^14 n/cm^2/s
Specific nuclear heating: 10 W/g
The neutron flux is not uniform in the vertical direction of the tube. In other words, the whole stucture I am...
Field of nuclear physics is way over my head and I need some information. My guestion is about the heat generated by neutron radiation on a stainless steel tube. How much will a tube say 10mm radius and 0,4mm wall thickness heat with a neutron flux of 10 W/g? The tube is sinked into the water...
Thank you for your answer gwolf. You are right, I have to check my assumption regarding helium conductivity. In this case there is no forced flow of helium. That´s why I might have to take into account a "cellural flow" between the two tubes enclosing the helium. A cellural flow occurs when...
Thank you for your reply Corus. I might have been a bit misleading with my definition about the slots. There is quite lot of slots in the device, but most of them (maybe 95%) are filled mostly with bolts to fix the supports between the flanges and grid plates. I have now modelled all possible...
Dear all,
I have some problems with heat transfer analysis, where the heat is generated with gamma heating. I have modelled the gamma heating in Abaqus using "Body heat flux" to an axisymmetric model (in 2D).The gamma heating is assumed to be instantaneous and the given volume of the gamma...
