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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

NRC okays construction permits for Hermes 2 test facility
The Nuclear Regulatory Commission announced yesterday that it has directed staff to issue construction permits to Kairos Power for the company's proposed Hermes 2 nonpower test reactor facility to be built at the Heritage Center Industrial Park in Oak Ridge, Tenn. The permits authorize Kairos to build a facility with two 35-MWt test reactors that would use molten salt to cool the reactor cores.

Westinghouse Electric Company recognizes the importance of supporting students pursuing a career in reactor physics. For this reason, Westinghouse will be sponsoring the first 100 student workshop registrants by covering their fees. Contact registrar@ans.org for a discount code before registering. Limited space available in each workshop. Once these seats are filled, you will be put on a waitlist. You must request a discount code before registering. No refunds will be made if you do not contact us before registering.
Organized by: SCALE team (Oak Ridge National Laboratory), scalehelp@ornl.gov
This 4-hour workshop explores key capabilities of the SCALE code system for neutron transport, depletion, uncertainty quantification, and sensitivity analysis, to gain practical insight into using SCALE for validation analyses as accepted by US regulators. Participants will learn how to perform similarity assessments, how to determine biases, and how to identify validation gaps. They will become familiar with SCALE’s graphical user interface Fulcrum, to create and validate input files, visualize 2D and 3D geometries, and explore various result files.
Agenda:
No prior SCALE experience is required for this workshop. Participants are encouraged to bring their laptops with SCALE 6.3.1 installed. SCALE 6.3.1 can be requested from RSICC (rsicc.ornl.gov/Default.aspx). Participants without a SCALE 6.3.1 license or without a laptop may still attend and follow along. The workshop material (presentations, input and output files for the demos and the hands-on sessions) will be made available to all participants. Information about SCALE can be found here: www.ornl.gov/scale
To join the conversation, you must be logged in and registered for the meeting.
