Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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.

Progress on NNB technology enables to demonstrate the N-NB driven current of around 1 MA with the efficiency of 0.155×1020nT−2A/W. A newly installed 110GHz ECH system has demonstrated efficient central electron heating (Te(0)>15keV) and local current profile control. Multiple pellet injection from high-field-top side into ELMy H-mode plasma has produced a high confinement plasma (HHy2~1.05) at high density regime (ne/nGW~0.7). The both-leg divertor pumping has enhanced He exhaust by ~40%. Ar-puff experiments have improved confinement at high density with detached divertor due to high pedestal temperature. Based on these progresses in each issue, discharge optimization has been made to demonstrate integrated high performance plasmas. In the two advanced operation regimes (the reversed magnetic shear (RS) and the weak magnetic shear high-βp ELMy H-mode), discharges have been sustained near the steady-state current profile solution under full non-inductive current drive with proper driven current profiles (High βp; HHy2~1.4 and βN ~2.5 with N-NB, RS; HHy2~2.2 and βN ~2 with fBS~80%).
