Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Judge temporarily blocks DOE’s move to slash university research funding
A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”
By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

To better understand the differences between R30003 alloy corrosion in tritiated water and in H2O, a detailed study was made of the oxide layers produced in the former medium. The R30003 alloy was selected because of its nuclear corrosion resistance and its hardness, ensuring leaktightness when assembled with soft alloys. The characteristics and morphology of the formed oxide were investigated in corrosion potential, passive, and passive-transpassive regions where breakdown occurs. With tritiated water, the repassive potential is slightly lower than that obtained with H2O. Consequently, localized corrosion, which leads to corrosion in oxide sublayers, is greater and is produced by the effects of excited radiolytic products formed by time-dependent O3H− diffusion into the oxide. If enough tritium decay energy is absorbed by the oxide layer, excited and ionized states of the oxide are formed. Thus, reactive radiolytic species and voids accumulate in a small volume below the oxide surface. Spreading of these voids causes oxide cracking, leading to peeling and wall formation. Mechanisms for both processes and the electrochemical properties are described. The majority of the ionic carriers are in the peels, contributing to oxide delamination and thus steel degradation.
