Keyword:ATOMS

ATOMS

---

When it is used in the initial conditions section of the input file, this keyword causes the initial inventory to be printed to the output file. In the inventory phase, this keyword starts the solution of the inventory equations over the time interval specified and causes the results (isotopic, elemental, spectral) to be output. After the ZERO keyword, it also causes pathways and uncertainty results to be output. It is the standard method of producing output; other options are SPECTRUM and RESULT. The time step is set to zero after the completion of the output, and so must be reset in subsequent steps using the TIME keyword.
