Decay heat precursors decay rates

Hi Jaakko,

I have a question regarding the output from SERPENT 1.1.19.
Does it produce decay heat precursors decay rates (1/sec)?

Thank you in advance!
Sasha.

Output data from SERPENT 2.1.24

Hello, Sorry, I have a question regarding the output data from SERPENT 2.1.24. I've used SERPENT 1.1.19 for the generation of cross-section data. These data are used as an input for a reactor physics code, and certain variables must be always provided to this code. I would like to use SERPENT 2.1.24...

Re: LAMBDA in the Delayed Neutron Parameters Output

Hello Jesse,

Looking at the order of magnitudes of LAMBDA, *_LIFETIME, *_GEN_TIME, I think that you're right.

Thank you very much for the clarification!

With best regards,
Sasha.

LAMBDA in the Delayed Neutron Parameters Output

Dear Jaakko, Excuse me, two questions regarding LAMBDA in the delayed neutron parameters part of the output (SERPENT 2.1.24): 1) Is my understanding correct that LAMBDA=Lambda_eff, which is the prompt neutron reproduction time, and It is equal to l_eff (the effective prompt neutron lifetime)/keff (t...

Flux Interpretation and Units in SERPENT

Dear Jaakko, I've seen several discussions on the forum regarding neutron flux estimation using detectors and flux units. Excuse me, I still have a few questions (Note: I am using Serpent 2.1.24): 1) TOT_FLUX is the total flux integrated over the geometry and all energy groups. In the User's Manual,...

Shuffle option

Hello Jaakko, Sorry, I have two questions regarding the shuffle option and modelling of control rods. I'm working on the modelling of a lead-cooled reactor using Serpent 2.1.24. I need to take into account extraction of control rod banks during burnup. I was thinking to create several lattices repre...
