Integrated Testing — Perform integrated experiments to characterize component, multiple
component, and facility performance in a fully representative operating environment.
Previous experimental work has provided the groundwork, but will not replace the need for integrated
testing as the last stage to resolve key knowledge gaps for power extraction and fuel cycle
components and facilities. This is especially true for in-vessel components where a Fusion nuclear
science Facility (a.k.a. component test Facility, Fusion development Facility and volumetric neutron
source) will be required to fully establish the engineering feasibility, reliability, safety, fuel
sustainability, and performance verification of the plasma chamber components. such a facility
would provide a test environment with significant neutron flux and fluence, in concert with all
other fusion conditions such as long operating times, magnetic field, etc.). The program should include
both highly instrumented scientific experiments to test, discover, analyze, and understand
the integrated phenomena and behavior, as well as aggressive iterations using multiple modules
for reliability statistics. it is also possible to use the facility to research, develop, and demonstrate
tritium self-sufficiency of a complete fuel cycle.
integrated testing will cover:
1. multiple, interacting effects in components activated only in a full fusion environment.
2. interactions among tritium breeding, extraction, processing, and containment in the
presence of plasma-wall interactions (PWi), and the plasma facing component interactions
with in-vessel and ex-vessel components.
