ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.
Meeting Spotlight

The behavior of hydrophobic catalyst in the isotopic exchange reactions H/D/T was analyzing by quantum chemical methods.The primary radiolytic effect was evaluated using a two-step radiolytic mechanism: a) the ionization of molecule and spatial redistribution of atoms in order to reach a minimum value of energy, characteristic to the new quantum state; b) the neutralization of molecule by capture of an electron and its rapid dissociation in free radicals. Chemical bonds suspected to break are located in the distribution region of LUMO orbital and have minimal bond energy.Evaluation of secondary effects taking place in polymeric structure in the presence of water was carried out through the study of the transition state resulted after the attack of HO radicals formed in the radiolysis of tritiated water.
