# Keyword:TAB1

TAB1 ia

This keyword causes the inventory data in columns 1 and 2, the number of atoms and grams of each nuclide, to be written to an external file (TAB1). Note that the stream number ia is now ignored. Both NOT1 and TAB1 may be used several times during a run to restrict and restore the output as required.

Example usage, where TAB1 output to the <fileroot>.tab1 file is turned on and off over several steps:

< -- Control phase -- >
...
FISPACT
* Title of the simulation
< -- Initial phase -- >
...
TAB1
