Operating and Geometrical Arrangement Requirements for Fusion Neutronics Testing

Neutronics tests in a fusion engineering test device will be required to verify the neutronics prediction capabilities (calculational methods and data base). This paper presents the requirements related to the neutronics test. These requirements include those associated with the operational environment (e.g., wall load, fluence, plasma burn time, etc.) and the ones related to the test module configuration (geometrical arrangements, minimum size for meaningful test information, boundary conditions, etc.). Both experimental consideration and neutronic analyses were carried out to quantify these conditions.
