|---|---|---|
| Windows HPC plugin | Submit jobs and tests to a Windows HPC environment | |
| Crucible | A fast-running metallic fuel performance code | Driven off of longer-running ALCHEMY runs |
| Depletion | Solves nuclear transmutation and decay problems in parallel | CRAM and Pade methods |
| TP's DIF3D plugin | Write input files for ANL's DIF3D code, run DIF3D, read DIF3D output state | Hex, RZ, RZTheta, and Cartesian geometry |
| Economics | Computes levelized cost of electricity for an ARMI scenario | Largely focused on fuel cycle costs (SWUs, feed, fab, etc.) |
| Equilibrium fuel cycle | Computes the implicit equilibrium fuel cycle quickly | Similar to ANL's REBUS-3 code |
| Fluxrecon | Computes continuous inter-assembly flux and power distributions | Essential for subchannel T/H analysis |
| Gamma transport | Updates power distribution considering the explicit transport of photons. | Important for sophisticated T/H calcs |
| Intrinsic source | Computes spontaneous fission source throughout ARMI scenario | Useful for startup detector signal analysis |
| TP's MC2 plugin | Write input files for ANL's MC**2-3 code, run MC2, read output state | Good for generating fast reactor cross sections |
| TP's MCNP plugin | Write input files for LANL's MCNP code, run MCNP, read output state | Pin detailed or homogenized |
| TP's NJOY plugin | Can drive LANL's NJOY code for a variety of nuclear data uncertainty purposes | Like covariance data |
| Nuclear Data UQ | Computes sensitivities of a core to each cross section using generalized perturbation theory. Loads covariance data from NJOY and evaluates the sandwich formula to determine the uncertainty in integral nuclear performance metrics due to nuclear data uncertainty. | Handles keff and reactivity coefficients so far. Power distribution planned. |
| TP's PARTISN plugin | Runs LANL's PARTISN code either as a global flux solver or as a simplified high energy resolution solver in a 2-step process for generating cross sections with MC2 in non-fissile regions (like reflectors) | |
| Reactivity control | Moves control rods up and down, performs criticality searches, finds highest-worth rods (in parallel), etc. | Depends on external physics solvers to compute keff |
| TP's REBUS plugin | Drives several features of ANL's REBUS fuel cycle code | Largely superseded by Equlibrium plugin |
| Reactivity coefficients | Computes kinetics parameters (like beta-effective), core-wide reactivity coefficients, and spatially-dependent reactivity coefficients in arbitrary sections of a core. | Essential input for transient analysis |
| TP's SASSYS plugin | Writes the core elements to input files for ANL's SASSYS code, including power and flow distribution, reactivity coefficient distributions, composition. Combines with a user-provided plant model to perform transient analysis. | Can also perform statistical sweeps to compute sensitivity of peak clad temperature (or other metrics) to various inputs |
| TP's Serpent plugin | Writes VTT's Serpent inputs for cross section generation | Mostly targeting SFR assemblies |
| Source term | Computes the source term | Important for safety analysis |
| Stability | Computes the zero power transfer function and the full power transfer function of a core using a plant transient model (e.g. SASSYS) running a frequency sweep of programmed oscillatory reactivity. The performs signal processing analysis to determine the phase and gain margins of stability for a plant. | Important |
| SFR Thermal/Hydraulics | Performs subchannel T/H analysis with a variety of TerraPower physics kernels including subchan and MONGOOSE. Also computes flow orificing required for a given x-year fuel management scenario without undercooling. | SFR/single-phase focused |
| VirDenT | Computes the reactivity feedback resulting from arbitrary 3D core mechanical perturbations. Essential for radial expansion and core restraint study. | Couples closely with subchannel T/H, core mechanical, and fluxRecon modules |
