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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The control rods of the KRB-I 250-MW(electric) boiling water reactor contain Vipac B4C powder in Type 304 stainless steel tubes as a neutron-absorbing material Because of an increase in the reactor coolant 3H activity, defective control rods were suspected. The hot cell examination of a highly exposed control rod revealed B4C losses. The mechanism of failure was shown to be B4C swelling and stress corrosion cracking of the absorber tubes, followed by B4C washout. The B4C volume swelling is ΔV(%) = 0.851x + 0.0449x2 [x = 10B decays in 1021(n,α)/cm3]. The tube cracking starts at 30 to 35% and the B4C washout at 50 to 55% local 10B burnup in the tubes.
