For getting SERPENT code

Hello I was using Serpent2 during my Phd at KAIST under professor Yonghee Kim. After my PhD, I came back to my country Bangladesh and working in Bangladesh Atomic Energy Commission(BAEC). BAEC is non-commercial organization. I want to continue my research using Serpent2. I contact with RSICC and req...

Xe135m microscopic cross section calculation

Hi Jaakko Now we are using Serpent 2.1.31 and also use set poi OPT [ VR XE135M ] to get the poison cross-section. We set the parameter 1 to treat Xe135 and Xe135m separately. Now in the output file, it is given microscopic and macroscopic cross-section and yield of Xe135 and Xe135m separately. But p...

Re: Fatal error in function HomoFlux:

Dear Jaakko, I have found a new Fatal error. Fatal error in function LUdecomposition: Matrix singular? Simulation aborted. still, I am using Serpent 2.1.27. Would you please check my input, it is a simple small CANDU 4 by 4 fuel matrix with additional 2 layers of reflectors. My intention is to calcu...

Fatal error in function HomoFlux:

Dear Jaakko, I am trying to calculate XSs and DFs for 2D CANDU core for fuel and reflector region. I am getting the error like this Fatal error in function HomoFlux: Zero or negative flux in group 1 Simulation aborted. I am using Serpent 2.1.27 What might be the possible error in my input. Regards M...

Re: Automated burnup sequence with branch capability

Dear Jaakko Thanks for your reply but still I am using Serpent 2.1.24. Any way I have one things to confirm. You mentioned " At the moment the output routine is there for testing purposes only, and the file (<input>.coe) is not recommended to be used for anything yet." Do you still recommend not to ...

Automated burnup sequence with branch capability

Dear Jaakko We can perform automated burn sequence with branch capability and it is very nice. But I am asking you different thing. Suppose I have 4 branches and first 3 was calculated perfectly but due to small mistake 4th branch did not run. But I need the 4th branch. Can I perform the 4th branch ...

Scattering matrixes order

Hi Jaakko B1_S0 (idx, [1: 8]) = [ 3.08714420E-01 1.4E-05 8.64302225E-03 6.8E-05 6.53812289E-05 0.00104 4.34455707E-01 9.2E-06 ]; the above line is scattering matrix for 2 group calculation. I arranged them like:Self scattering in fast group, up-scattering, down-scattering, and Self scattering in the...

Re: microscopic cross section calculation

set poi "<opt>", using this option we can calculate fission product poison cross section(I-135, Xe-135, Pm-149 and Sm-149 and absorption of Xe-135 and Sm-149). My question is that the microscopic absorption cross section of Xe-135 calculated by Serpent2, is it homogenized or not? Best regards Motalab

Re: Fatal error in function ScoreTransmuXS

Sorry to bother you. I found a mistake in my input file while I am setting parameters for Group Constant generations.

Thanks
