Abstract Scope |
No dedicated fusion facility to study the transmutation effects in prospective fusion reactor materials exists. Therefore, the engineers and scientists designing the fusion reactors that will be constructed in the next two decades must rely on simulations of transmutation response to inform material performance predictions.
The reliability of transmutation predictions must be tested in creative ways until fusion reactor operation data becomes available. In this paper we will describe some recent work to test the direct transmutation output from inventory simulation codes, which are the tools able to predict the evolution in material composition (transmutation) under neutron irradiation. Successes include the use of atom probe tomography (APT) to measure transmutation, where inventory codes also help to improve the APT methodology.
We also highlight more indirect validation of transmutation predictions via comparison of simulations with radiological measurements, that can be successfully obtained even from low flux fusion neutron sources. |
