Research Needs for Magnetic Fusion Energy Sciences - US Burning ...

obtained from recycling techniques and guidelines for the free release of fusion-specific materials,
both of which are beneficial to fission industry and Us regulatory organizations.
Other Scientific benefits
integrated modeling continues to produce advances on research, knowledge, and technology for
all science fields. Given the complexity of the fusion geometrical scale and multi-physical phenomena,
development of a computer-based simulation capability to display fusion plasma chamber
behavior poses many challenges and opportunities for innovations in mathematics, computer
graphics, and architectures. These advancements will lead to further development of efficient
multi-physics algorithms, methods, and techniques.
Connections to Other Thrusts
The integrated demo design activities, by definition, must strongly couple to all aspects of the fusion
program and the thrusts that support them, since demo provides a focus in guiding fusion
R&d. These include, for example, coupling to physics thrusts on alpha physics (3), plasma control
(5), plasma dynamics (8) and transient event control (2), to the superconducting magnet thrust
(7), to plasma edge and interface thrusts (9-12), and to fusion power and material thrusts (13, 14).
The FnsF activities couple to Thrust 13 where a progressively more integrated modeling and experimental
program on power extraction and closing the fuel cycle leads ultimately to fully integrated
experimental validation in an FnsF. They also couple to Thrust 16 where a spherical tokamak
configuration is proposed for FnsF.
The integrated model provides an effective mechanism in integrating models from other thrusts
as well as ongoing R&d results in creating powerful and effective simulation tools. These specific
models include those mentioned in Thrust 13 for power extraction, plasma fueling and tritium
recovery as well as the detailed material modeling described in Thrust 14. The development of the
integrated model would closely follow the development of the FsP, covered in Thrust 6, to ensure
compatibility. For example, the model when linked to the simulation capabilities being envisioned
in the FsP would be able to simulate the responses of the plasma facing surface, as well as the corresponding
in-vessel component behavior, to various fusion plasma shots.
