NOFISS.md¶

NOFISS

This keyword stops the fission yield data from being input and processed during the preparation of the arrayx file. It causes substantial speed-up of the calculation, but will cause errors in the inventory predictions if fission is important. It is advisable not to use this keyword if the initial inventory contains actinides.
