Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Radiation-induced outgassing was measured for several metals exposed to 60Co gamma radiation. The metals, in the form of tubes or rods, were placed in a Type 304 stainless-steel vacuum system. It was determined that the array of the pins (either square or hexagonal) did not significantly affect the results. The measurements for Type 304 stainless steel varied from (1.42 ± 1.75) × 10−9 (Pa - ℓ)/(cm2 ·s) per Mrad/h for a surface-to-volume (S/V) ratio of 8.64 cm−1 to (9.58 ± 3.81) ×10−10(pa - ℓ)/(cm2·s) for an S/V ratio of 3.08 cm−1. For Type 316 stainless steel, the determination was (1.18 ± 0.49) × 10−9 (pa - ℓ)/(cm2·s) per Mrad/h, for aluminum the value was (6.24 ± 17.2) × 10−10 and for carbon (2.28 ± 0.59) × 10−9 (pa - ℓ.)/(cm2·s) per Mrad/h. The determinations were made by comparing the rate-of-rise pressure curves with and without gamma radiation, and large errors resulted when the differences were small.
