Development of coupled neutronics and fuel performance analysis capabilities between Serpent and TRANSURANUS

Towards grain-scale modelling of the release of radioactive fission gas from oxide fuel. Part II: Coupling SCIANTIX with TRANSURANUS

“…(For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.) 7 The model for the grain-boundary micro-cracking is strongly sensitive to the inflection temperature T infl , as demonstrated in Ref. [48].…”

“…However, the semi-empirical nature of the model implies some limitations in its applicability, contributing to an overestimation of the fission gas release that could be reduced by improving the model parameters. 7 Lastly, we consider the release-to-birth ratio (R/B) of the shortlived 85m Kr and 133 Xe, for radioactive fission product release. For comparative analysis, we provide the results of the ANS 5.4e2010 methodology, a state-of-the-art semi-empirical approach to estimate the R/B in stationary conditions according to the thermal power generated per unit length of the fuel rod and the burn-up.…”

Extending Transuranus Burnup Model for Agr-Like Fhr Fuel Design

“…Moreover, the new TUBRNP approach paves the way to develop TUBRNP versions for other advanced fuel types in various SMR. A higher fidelity alternative would be the approach by Suikkanen et al (2020) who couples Serpent and TU at the expense of longer computational time. The method presented in Suikkanen et al (2020) requires about 25 days using a 72 cores and 2 TB of RAM.…”

Development of multiphysics coupling system for nuclear fuel rod with COMSOL and RMC

“…The OpenFOAM Fuel Behavior Analysis Tool OFFBEAT was coupled with Monte Carlo code Serpent for determining an accurate fuel radial power profile (Scolaro et al, 2019). The Monte Carlo neutron transport code SERPENT 2 was coupled with the fuel performance code TRANSURANUS in two-way strategy to enhance fuel performance analyses (Suikkanen et al, 2020) and the Monte Carlo code RMC was coupled with multiphysics software COMSOL for FCM fuel segment (Weng et al, 2021). Recently, coupling between the fuel performance code TRANSURANUS and neutronics solver Serpent was further improved by transferring and utilizing nuclide compositions within the coupled calculations (Rintala et al, 2022).…”
