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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

NRC news roundup
Here’s a look at some recent announcements from the Nuclear Regulatory Commission.
Summer SLR: The NRC this month published its final environmental impact statement for Summer Unit 1’s subsequent license renewal application. Dubbed a supplemental EIS, the report is an important step in determining if Dominion Energy can continue operating its 966-MWe Westinghouse pressurized water reactor unit for an additional 20 years beyond August 6, 2042, the current end of its license.

Price: $49
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.
