Hi, thanks for your response. I think i have the full installation( about 1.4 GB). I want to calculate the energy released from fission reactions from a spherical geometry of Uranium with the neutron source at the center and Beryllium as shielding, I have the spectrum of the neutron source...

Hi, i am new to simulation and for my thesis i have to make a simple simulation by using mcnp4c2. Is anybody familiar with this version of MCNP? I need to calculate the fission reactions per second in a geometry of a spherical sub critical reactor of Uranium with low percentage of U 235 with...

Hi, thanks for your responce . I found the values of neutron flux for several sources so it is not necessary to simulate the process! I will use them directly.

Hi, Can someone suggest me an open source code for simulation of (a,n) reactions? I want to build a geometry(sphere) with an a-decay radioisotope covered by Beryllium and count the neutron production. Thanks a lot

I read somewhere that taking the average energy of the electrons to calculate the energy deposition is quite different results.

Hi, thanks for your reply Yes, i thought that! My problem now is to determine with a Monte Carlo the energy of each decay for the electrons as all the neutrinos escape.and the spectra is not linear.

Sr-90--->(~30 Years beta)--->Y-90---->(~2.8 Days beta)--->Zr-90(stable). the main component is a sturdy container of a radioactive material (the fuel).Thermocouples are placed in the walls of the container, with the outer end of each thermocouple connected to a heat sink . Radioactive decay of...

Sorry about that! As i said i am rookie!

That's the point of my research, to determine the thermal power degradation with time. The environment is space. I want to predict the capability of Sr-90 for RTG applications

Hi, thanks for your response. A given mass of Sr-90 will has a raised temperature due to the collisions of the electrons of the beta decay with the medium (Sr-90)

Hi, I want to develop a Monte Carlo simulation to determine the temperature of a beta radioisotope (Sr-90) of a given mass for my master thesis in Computational Physics. I am rookie to simulations. How much time will take to develop such a code. Thnaks a lot

I found that https://permalink.lanl.gov/object/tr?what=info:lanl-repo/lareport/LA-UR-17-21903 The problem that i told that was unsolvable is for me to make a simulation like that with my capabilities right now! I will simply give up this idea and try to search something by far easiest.

My first thought was to find a existing code with maybe an interface to make the geometry of the core and the element that consists of and run the simulation to calculate some quantities. I think that this is by far easier than writing my own code. I find some proper codes but only with a...

I am rookie but not so much!
