Division Spotlight
Fuel Cycle & Waste Management
Devoted to all aspects of the nuclear fuel cycle including waste management, worldwide. Division specific areas of interest and involvement include uranium conversion and enrichment; fuel fabrication, management (in-core and ex-core) and recycle; transportation; safeguards; high-level, low-level and mixed waste management and disposal; public policy and program management; decontamination and decommissioning environmental restoration; and excess weapons materials disposition.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Two experiments directed to a search the experimental conditions for the creation of the hot plasma bunch with β~1 at the multimirror trap GOL-3-II are described. In the first one the hydrogen cloud of 0.5 m length and ~1016 density cm−3 was heated in a short (~ 0.5 m) section with relatively small magnetic field placed in the 12-m solenoid with 9 T magnetic field in mirrors. Plasma pressure was measured by diamagnetic loops and reached βvac ≈0.4. In the second experiment the dense bunch is created by pellet (LiD, (CH2)n) injection into the electron-beam-heated plasma. After beginning of the beam injection the pellet is evaporated and ionized, then dense plasma is magnetized and as result dense bunch (ne=1016-1017cm−3) with abrupt edges is created. After heating the bunch has expansion velocity up to 3·107cm/s.
