Discrepancy of K-eff by different "opti" mode

Dear Serpent team, I am currently working on a research reactor core design using Serpent 2.1.24. We are doing equilibrium core search and the "set opti" card is considered to reduce memory consumption. The problem is the k-effs with different "opti" mode are very different. For your information, I ...

ENDF-7.1 S(a,b) from MCNP6

Hello, Is there any serpent user has ever used the ENDF-7.1 S(a,b) library from MCNP6 in Serpent? I am currently converting the ENDF-7.1 library from MCNP so it can be used in Serpent. I don't have problems in converting the neutron reaction library, but I have a problem with the S(a,b). In my test ...

Re: Problem in running Serpent 2 by using JENDL4.0 library

Thanks Dr. Jaakko. I just tested the JENDL4.0 library using Serpent 2.1.21 and it works fine.

Problem in running Serpent 2 by using JENDL4.0 library

Dr. Jaakko, I am currently trying to use the JENDL4.0 neutron library in Serpent. I successfully used the JENDL4.0 library when doing single calculation (0 burnup) by using Serpent 1 and Serpent 2, but then I encountered a problem when doing burnup calculation using Serpent 2. The burnup calculation...

Print out cycle-wise tally result

Dr. Jaakko,

In serpent, is it possible to print out cycle-wise tally result by modifying the source code? Would you teach me how to do it?

Thank you.

Strange capture cross sections behavior in Serpent

Picture1.png Currently we are doing MCNP/DIF3D calculation for fast reactor analysis. For verification of the cross-sections generations, Serpent was used. The result above is the 9-groups capture cross sections for the active core region. Group 1 has the highest energy. There seems to be something...

Re: Test case 1: BWR burnup calculation

This is the result from KAIST for the test case 1 "bwr5" and "bwr41". No change was made in the input file. I will update the result for bwr113 and bwr436 later after the calculation has been done. The CPU type is Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz. BWR5 Optimization mode: 4 OpenMP reproducibi...

Re: "TMP" Option

Hello,

Do you have example of the NJOY input file to generate the 0 Kelvin cross sections? I want to try to the on-the-fly Doppler Broadening based on the explicit treatment of target, but I failed to generate the 0 K library.

Thank you,

Donny
