College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Quasi-symmetry condition, which demands that B2 does not depend on one from two angles in Boozer coordinates, is analyzed for stellarators with planar circular axis. In stellarator approximation this condition is reduced here to two equations. The first one imposes a restriction on the helical field which can be satisfied by a proper choice of satellite helical harmonics. At the same time problem remains to suppress poloidal asymmetry of B2 related with toroidicity, the condition described by the second equation.
