A new version of CLASS is available for registred user.
The main changes are related to the equivalence model and new ANN weights for mean cross sections predictions
Change Log
- New Equivalence Models (see /documentation/Manual/USEGUIDE.pdf)
Equivalence Model based on PWR_MLP_PWR_MOX for a PWR loaded with MOX containing americium
Generic Equivalence Model for non breeder reactor (using a ANN to predict kinfinite)
Generic Equivalence Model for breeder reactor (ANN predicting keffective @ beggining of cycle)
Equivalence Model which gives the fissile content in the fresh fuel such as the average kinfinite over time is contained in a range.
- Equivalence Models datas
Better default weights for Baker and Ross formula (for FBR-Na)
ANN weight for a PWR-MOX with Am reactor
ANN weight for a PWR-UOX (using Generic non breeder model)
ANN weight for a FBR-Na MOX (using Generic breeder model & average kinfinite)
- Mean Cross section datas
ANN weight for a PWR-MOX with Americium
- Utils
Add utils for the user to train and test neural networks for the new equivalence models
- Other
Manual and doxygen have been updated
Examples have benn updated
Format of .nfo files have changed (see manual)
Install procedure has been simplified : just type ./install.sh in the CLASS root folder : It sets automaticaly path to decay data base and add automatically environment variables. Type ./install.sh -h to know available options
Package can be downloaded in the DMSF tab (choose version 4.1.0) : https://forge.in2p3.fr/projects/classforge/dmsf (forge account requiered)

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).

The package has been modified to integrate the new c++11 standard since svn 1273.
This release fixes an important bug that prevented downloading outfiles on some Cream CEs.
