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.
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

NC State celebrates 70 years of nuclear engineering education

The Department of Nuclear Engineering at North Carolina State University has spent the 2020–2021 academic year celebrating the 70th anniversary of its becoming the first U.S. university to establish a nuclear engineering curriculum. It started in 1950, when Clifford Beck, then of Oak Ridge, Tenn., obtained support from NC State’s dean of engineering, Harold Lampe, to build the nation’s first university nuclear reactor and, in conjunction, establish an educational curriculum dedicated to nuclear engineering.
The department, host to the 2021 ANS Virtual Student Conference, scheduled for April 8–10, now features 23 tenure/tenure-track faculty and three research faculty members. “What a journey for the first nuclear engineering curriculum in the nation,” said Kostadin Ivanov, professor and department head.

Tritiated water and some tritiated organic compounds (leucine, glucose and thymidine) were administered to rats by oral ingestion and the content of organically bound tritium (OBT) in subcellular fractions (cold PCA soluble, ethanol-ether soluble, hot PCA soluble and alkali soluble) of the liver were determined at various time points after ingestion. In the case of tritiated water, the initial OBT content was high in the cold PCA soluble fraction, which contains low molecular weight components, but as the time proceed the OBT was distributed to other fractions, which contains relatively high molecular weight components. Significant time variation in the OBT content was observed in the hot PCA soluble fraction containing nucleic acids, in which the OBT content, expressed as percentage of OBT content in all fractions, changed from 1 % at 12 hours to 15 % at 50 days. In the cases of tritiated organic compounds, the subcellular distribution of OBT was widely changed owing to their biochemical and metabolic characteristics. Thus, the OBT distribution among subcellular fractions was changed depending on the chemical form at ingestion and on the time after ingestion. The OBT distribution among four subcellular fractions after 22 day' continuous ingestion was also dependent on the chemical form of ingested tritium. Present results should be taken into account for internal dose estimation of tritium in different chemical forms.
