Examples

Inputs which demonstrate potential applications for TMAP8 capabilities, along with walk-through guides which should in theory allow users to leverage prior work.

Fuel cycles from Abdou et al. and Meschini et al.

Because TMAP8 is built on MOOSE, it brings MOOSE's capacity to solve ordinary differential equations using ScalarKernels. These can be quite useful to model parts of the system at high levels of abstraction while working with detailed models of specific components. As examples, we propose two fuel cycle models. The first model re-creates the fuel cycle model described in Abdou et al. (2021) as a high-level abstraction of a fuel cycle in a potential fusion power plant. The second model re-creates the fuel cycle model described in Meschini et al. (2023), which models the tritium fuel cycle for ARC-and STEP-class DT fusion power plants.

Divertor Monoblock

TMAP8 is used to model tritium transport in a divertor monoblock to elucidate the effects of pulsed operation (up to fifty 1600-second plasma discharge and cool-down cycles) on the tritium in-vessel inventory source term and ex-vessel release term (i.e., tritium retention and permeation) for safety analysis. This example reproduces the results presented in Shimada et al. (2024).

Pore-Scale Tritium Transport in Imported Microstructures

This example demonstrates TMAP8's capability to (1) generate pore structures from input images, and (2) perform pore-scale simulations of tritium transport on these pore structures based on the model described in Simon et al. (2022). This example highlights the effect of pore interconnectivity on tritium transport.
