Hello , I was trying to calculate the effective absorption cross section ( group constant) of U-238 in the resonance region between neutron energies (1 ev - 10 kev) but as you can see from the picture U-238 has a lot of resonance at this region, I was wondering if there is a way I can obtain...

Thank you very much

By a simple procedure , what should I do when I'm going through the thermal hydraulic design of nuclear reactor core...? .. I put initial guesses for the core dimensions ( fuel , clad , gap , length) initial guess for the fuel element pitch desired power ... I've found q'' critical heat flux...

Thank you very much that helped a lot. :)

Zircaloy-4 melting point what is the melting temperature of Zircaloy-4 ? ..

I want to calculate the average thermal conductivity of UO2 by : 1/(To-Tf) * ∫To->Tf dT K(T) any one can provide me anything about the thermal conductivity of UO2 as function of temperature or any measured data in a range of temperature.

Any one has some links, papers... anything describes the maxwell-boltzmann distribution that characterize neutrons in thermal equilibrium with the reactor core material at specific temperature...? I want to get a crude estimation of energy-dependence neutrons flux for energies below 1 eV.

Yeah , I've read this paper before... Thank you very much , I wish you the best :)

I have this class project to design a full reactor with complete calculations excepts the safety systems , its PWR similar to AP-600 , and the control rods are just a stage , I'm following the steps in Chapter.11 " nuclear reactor analysis" for "Deuderstadt & Hamilton" if you're familiar with...

Thank you.. :)

Thank you again "Astronuc" with you're amazing links , and that idea sounds great , but this hollow in the control rod how it would effect the cosine shape of flux distribution in the core? ... Thanks a lot Jim for those links, I found some useful pdf files among them could help a lot , really...

yeah I know "filled" and "field" , I made copy and paste for the paragraph above , I thought field would mean something different, not sure of a misspelling. .. I thought the same at the first place , if we have two detectors have the same gas and the same volume , one is detecting a high...

Hi, I would appreciate it if someone could explain these expressions to me. I was reading about Gas field detectors from " Radiation Detection and Measurements" for "Knoll" and paticulary in chapter five "The gas field detectors are commonly used in dose measurements. In this case, the...

Thank you very much "jim hardy" and thank you for the pdf file , No I'm not familiar with "Chart of the Nuclides" but I saw the link "Astronuc" posed below and I'm getting familiar with its very amazing such data are hard to find through Google. ... Thanks "Astronuc" that made many thing much...

Hi, I was reading about PWR control system and I saw that control rods are stainless steel tubes encapsulating a Hafnium absorber material , it has Excellent mechanical properties and exceptional corrosion-resistance properties allow its use in the harsh environment of a pressurized water...
