Reason
Shimada et al. in 2018 published, as part of the US-Japan PHENIX project, a study of deuterium retention in neutron-irradiated single-crystal tungsten. In this project, single-crystal tungsten samples were irradiated in HFIR and then exposed to a deuterium plasma in the Tritium Plasma Experiment at INL. In the paper, they used a modified form of TMAP4 (potentially an early version of TMAP7) in order to determine the parameters of the single modeled deuterium trap and match thermal desorption spectroscopy measurements generated post plasma exposure.
This case could serve to be updated within TMAP8, benchmarked against the previous TMAP4 results, and explored further to expand TMAP8's V&V library.
Design
Construct a tritium diffusion and trapping simulation based on the above paper. A good starting point within the current V&V library to base this on is likely val-2d (Docs, Input permalink)
Impact
A new validation case for TMAP8.
