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.
Radiation Protection & Shielding
The Radiation Protection and Shielding Division is developing and promoting radiation protection and shielding aspects of nuclear science and technology — including interaction of nuclear radiation with materials and biological systems, instruments and techniques for the measurement of nuclear radiation fields, and radiation shield design and evaluation.

NRC’s Inspector General issues report
Overall findings of a survey of Nuclear Regulatory Commission personnel indicate that while the NRC maintains a few strengths compared to external benchmarks, results have declined since 2015 in a number of areas, according to a recent report from the NRC’s Office of the Inspector General (OIG).
The survey was conducted in February 2020 by Willis Towers Watson, a global risk-management, insurance brokerage, and advisory firm that has partnered with the OIG for more than 20 years to assess the NRC’s safety culture and climate, as well as other aspects of employee experience.

A preliminary assessment of the prospects of tritium assisted D-D based fusion-breeders (FB) is performed. For this purpose, the D-T STARFIRE and the Cat-D WILDCAT tokamak designs are converted into FB's. Two tritium sources are considered for T-assistance - the FB blanket (using Li or 3He) and the client fission reactors. The TCD modes of operation, in which the 3He exhausted from the plasma is converted in the blanket into T which is fed back to the plasma, are found most promising of all D-D based FB's. Their profitability is somewhat lower than that of the D-T FB's, but they offer ∼50% higher support ratio and simpler blanket designs. T-assistance from client reactors might significantly improve the economics of FB's.
