Updates in manual (Version November 15, 2010)

Post by Jaakko Leppänen » Tue Nov 16, 2010 12:30 pm

Recent changes in the Serpent User's Manual (http://montecarlo.vtt.fi/download/Serpent_manual.pdf) regarding update 1.1.14 include:

1) Doppler-broadening rejection correction: Doppler-broadening rejection correction (DBRC) on free-gas scattering kernel can be applied by setting the "dbrc" option (Sec. 5.6).

2) Universe symmetry option: Core quadrants and other 1/4 symmetries can be handled without repeated boundary conditions using the "usym" option (Sec. 5.7).

3) B1 fundamental mode calculation: B1 fundamental mode calculation and group constant generation in the critical spectrum can be applied by setting the "fum" option (Sec. 5.16). NOTE: This is not the same thing as the B1 iteration in previous versions.

4) Pre-defined energy group structures: Pre-defined energy group structures for detectors and B1 fundamental mode calculation can be set using grid type 4 with the "ene" card (Sec. 7.1.2).

There are also some new output parameters, such as spontaneous fission rates and group constants from B1 calculation.
