Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

A local model capable of simulating the cord-integrated emission of spectral lines in the TJ-II stellarator has been developed for inferring local parameters. The procedure was implemented on a numerical code, which starting from given analytical profiles of local emissivity, ion temperature, and toroidal rotation calculates the cord-integrated emission spectra along a selected line of sight. Additionally, the procedure is capable of simulating the toroidal and poloidal velocity contributions for a selected spectral line taking into account TJ-II magnetic topology. Results show good agreement between measurements and numerical simulations for the integrated intensity and ion temperature, and a consistent integrated toroidal rotation velocity, which depends on the emissivity profile.
