Engineering Scaling and Quantification of the Test Requirements for Fusion Nuclear Technology^a

For integrated testing of fusion nuclear components, it is likely that the test device parameters will not match the device parameters of a full scale fusion reactor because of cost constraints. This will result in changes in the behavior of the test module and limit the ability of the test to resolve key nuclear issues. However, it may be possible to modify the test module in order to retain the important aspects of the issues over a range of test device parameters. In order to understand and quantify this range and set requirements for blanket testing, analyses of several aspects of blanket operation were performed. The results suggest that a useful integrated test device should have at least 1 MW/m² neutron wall load, 0.2 MW/m² surface heat flux, 20% availability, 500 s burn length, and 0.5 m² by 0.3 m per test module.
