CLASS

Dear CLASS users,

A brand new version of your favorite dynamical fuel cycle code has just been released.
The major update is related to the handling of reactor data bases. The user can now create his own model to predict fresh fuel fissile content (EquivalenceModel) and mean cross sections (XSModel). Additionally, the Bateman solver can be overloaded thanks to the IrradiationModel class. Futhermore, additional EquivalenceModel has been set up, such as neural network, baker & ross , quadratic. The prediction of mean cross sections can be made by the use of neural network using the TMVA module of Root software. In the package, several data bases are provided allowing to simulates : PWR-UOX (with variable enrichment), PWR-MOX, FBR-Na (MOX).

What's new ?
Documentation
-an user manuel
-a doxygen

New features :
The Physics Models : This class and derivative's allow the user to set up new equivalence model Cross section model and Irradiation model (bateman solver).
handling of fission product : is now working. However, as only (n,gamma); (n,fission) and (n,2n) reaction are handled , some fission product may be predict with a low accuracy.
CLASSFuelPlan: allow to change fuel type and/or burnup during Reactor life time.
And other surprises to be discover by reading the manual.
New Data bases :
FBR-Na (MOX), PWR-UOX (with variable enrichment).

package can be downloaded in the DMSF tab : https://forge.in2p3.fr/projects/classforge/dmsf (forge account requiered)
