### Inventory for accident progression
For each of the reactors, inventory for accident progression calculations with MELCOR was generated and is provided in this repository. To consider the most conservative conditions of the individual cores, a core-average or system-average inventory file was generated as follows:
For each of the reactors, inventory for accident progression calculations with MELCOR was generated that is provided in this repository. To consider the most conservative conditions of the individual cores, core-average or system-average inventory files were generated as follows:
* HTGR and FHR: core-average inventory at the state of equilibrium operation
* HPR: core-average inventory at end-of-life
* SFR: core-average inventory at the end of an equilibrium cycle
* MSR: system-average inventory (considerin the fuel salt inside the core and the loop) at end-of-life
* MSR: system-average inventory (considering the fuel salt inside the core and the loop) at end-of-life
For use in MELCOR, the core-average or system-average inventory was decayed for 10 days in order to allow consideration of accurate inventory as a function of time during accident progression.
For use in MELCOR, the core-average or system-average inventory was decayed with ORIGEN for 10 days in order to allow consideration of accurate inventory as a function of time during accident progression. 10 days was deemed sufficient for this purpose.
The core-average or system-average inventory as a function of 10 days of decay is provided in the form of an ORIGEN concentration file (F71 file) and as JSON-formatted inventory interface (II.JSON). The README files in the individual sections provide links to the specific files.
It is noted that many of the inventory result files were generated with the TRITON reactor physics and depletion sequence. By default, this sequence normalizes the inventory to match 1 metric ton initial heavy metal (MTIHM). For easier use of the inventory files, both the normalized inventory and the inventory scaled to the actual core mass is provided.
