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.

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 general dynamic model consisting of 14 compartments simulating the distribution of tritium into milk and its constituents in lactating dairy cows was developed. The model is calibrated to fit the results obtained in two experiments, where cows were given tritiated water in one experiment (A) and tritiated hay in the second (H) one. The model estimates the activity concentration in the whole milk and its constituents as a function of time. In the next step the COWTRI model will be fitted to a “normalized” cow for which the weight, the daily intake of organic bound hydrogen (OBH), the milk faeces- and urine production are defined. In this version of the model the normalization procedure is only performed concerning intake of OBH. The purpose with this detailed model was to estimate the contribution of the ingested tritium to OBT in milk besides the whole milk itself. From this information it will be possible to simplify the model to one organic part and one non organic part of the milk. The model needs further testing against independent data before it can be simplified for a close assessment model attributed to accidental and continuous operational releases of tritium to an environment where the exposure pathway via milk consumption has to be considered.
