Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

IAEA promoting nuclear energy with G20
The International Atomic Energy Agency launched a collaboration with the Group of 20 this week to highlight the key role that nuclear energy can play in achieving energy security and climate-change goals.
The aim of this first-of-its-kind partnership with G20—the world’s largest economic group—is to build momentum for nuclear power. This is the first time the IAEA has presented to G20 on issues relating to nuclear power.

The ray-tracing procedure for modeling the power deposition into electron cyclotron resonance (ECR) discharge in an axisymmetric mirror trap with longitudinal launch of microwave power is presented. To deal with cyclotron absorption for normal waves of magnetized plasma propagating nearly along the magnetic field in the vicinity of electron cyclotron frequency approximate dispersion relation has been derived using Stix components for microwave electric field. Calculations have been performed for parameters corresponding to ECR multicharge ion (MCI) source (IAP RAS) as example. It is shown that the efficient power deposition into ECR discharge within single pass of radiation through the plasma column may be provided under conditions that parasitic cyclotron resonance (before the plug) is outside the plasma volume and the electron density in the vicinity of the main resonance is undercritical. This is in a qualitative agreement with experimental results.
