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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

The MHD pressure drop was measured by providing a lithium circulation loop of 40 lit/min and 0.3MPa head with a square test section of 2a=15.7mm × 2b=15.7mm or a rectangular one of 2a=26.8mm × 2b=ll.lmm inner cross-section made of tw=2.1mm thick 304-SS walls. The experiment covered ranges of B=0.2–1.5T (Ha=200–2100), U=0.2–4.0m/sec (Re=500–38000), and TLi=309–380°C. Theoretical prediction was made on an assumption of a uniform electric current density, neglecting the friction with walls. The MHD pressure gradient -dP/dz is given by -dP/dz = KpσfUB2 where Kp= C/(l+a/3b+C) and C=σwtw/σfa. The theory agreed well with the experimental data for both the square and rectangular test sections. Under the ununiform magnetic field of the exit, the pressure drop data agreed with an approximated prediction of Δ P= ∫KpσfUB2(z)dz.
