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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

RP3C Community of Practice’s fifth anniversary
In February, the Community of Practice (CoP) webinar series, hosted by the American Nuclear Society Standards Board’s Risk-informed, Performance-based Principles and Policies Committee (RP3C), celebrated its fifth anniversary. Like so many online events, these CoPs brought people together at a time when interacting with others became challenging in early 2020. Since the kickoff CoP, which highlighted the impact that systems engineering has on the design of NuScale’s small modular reactor, the last Friday of most months has featured a new speaker leading a discussion on the use of risk-informed, performance-based (RIPB) thinking in the nuclear industry. Providing a venue to convene for people within ANS and those who found their way online by another route, CoPs are an opportunity for the community to receive answers to their burning questions about the subject at hand. With 50–100 active online participants most months, the conversation is always lively, and knowledge flows freely.

The remaining-life estimation of components is acquired in three steps: 1. Calculation of the life consumption indicates where tests on exposed material should be carried out. 2. Tests on exposed material are carried out on most exposed parts to evaluate the real creep degradation of the exposed material. 3. Continued operation is based on the results of the precalculation and the creep degradation of the material. At the next inspection the material tests will indicate whether a prolonged safe operation is possible.Material tests for remaining-life estimation are based mainly on replicas by which the creep life can be evaluated more quickly, more easily, and at lower cost than by any other method, presuming that the creep degradation starts from the outer surface of the parts. Replicas are then most effective in the time-to-failure estimation of parts, although they allow a high life exhaustion. After 6 yr of experience, not even unscheduled repair has been necessary for inspected parts.
