Reactor models sorted by input file features
While every advanced reactor has unique characteristics, with different coolants, fuel shapes or control mechanisms, most NEAMS tools are at their core rather reactor-agnostic and thus there are many similarities in the input files. The reader may find below an index of the features that are present in the input files of the virtual test bed. If the exact feature is not present for the reactor you wish to see it for, the inputs for another reactor type will likely help creating it.

Restarting from a previous simulation
Transient simulations are often started from stable steady state initializations rather than uniform power, temperature, flux, etc distributions. This can be done in numerous ways:
Checkpoint
Documentation for the Checkpoint system
Molten Salt Fast Reactor loss of flow transient documentation and inputs
Molten Salt Reactor Experiment reactivity insertion transients documentation and inputs
Pebble Bed Fluoride salt cooled High temperature Reactor Plant multiphysics documentation and inputs

Binary restart
Binary restart is only used by Griffin. It is only used to restart the neutronics simulation. Any MultiApps has to be initialized using another restart solution. For Checkpoint, the additional Problem/force_restart=true must be specified. The MRAD and PBMR-400 models listed below are an example of this.
