Statement of the problem or situation that is being addressed:
The Department of Energy, Office of Fusion Energy Sciences is seeking the development of wrap-able radiation-resistant electrical insulators for superconducting magnet coils used in fusion energy reactor systems. These insulators must: (1) exhibit low gas generation under irradiation, (2) have higher pot life, and (3) exhibit attributes of insulation systems with high bond and higher strength and flexibility in shear. These insulators must demonstrate considerable cost reduction using cost-effective materials and fabrication processes.
General statement of how the problem is being addressed:
During the proposed project, the company will continue developing metal oxide nanoparticle and organic polymer composite-based wrap-able, radiation-resistant electrical insulators.
Innovations will be incorporated to achieve radiation resistance, high mechanical strength, high thermal stability, and high chemical resistance. Overall, the proposed technology will improve both radiation-resistance and electrical insulation for superconducting magnet coils used in fusion reactors helping to achieve DOE program goals for fusion energy reactor systems.
What was done in Phase I:
Phase I demonstrated the development of nanoparticles incorporated hybrid polymer composite thin-film insulator samples and evaluated their thermal, mechanical, and high field dielectric performance before and after cobalt-60 gamma (~190–191 kGy) and ionizing nuclear radiation exposure. The radiation resistant electrical insulator film samples show promising results of:
(1) extended pot life, (2) bonding strength to metal substrates, (3) high thermal and mechanical stability, (4) electrical resistance, and (5) resistance to gamma and ionizing nuclear radiations.
What is planned for the Phase II project?
In Phase II, the company will (1) optimize formulations and processing of composite polymer samples, (2) investigate and evaluate their radiation-resistance electrical insulating performance under cobalt-60 gamma and ionizing nuclear radiations at room and cryogenic temperatures, and (3) develop a method for the scale-up production of composite polymer insulator samples.
Commercial applications and other benefits:
The metal oxide nanoparticle-incorporated organic polymer composite coating proposed for DOE advanced radiation and electrical insulators can be adapted for use in medical devices for cancer therapy, medical imaging systems, high-field accelerator magnets motors/generators in extreme conditions (space missions, military and commercial satellites, military operations in cold climates), and aerospace equipment.
