Getting Started with Cyclus

To model fuel cycles, you will need to install two things: first the main codebase (called Cyclus), and then a set of fuel-cycle specific archetypes (called Cycamore).


In the cyclus ecosystem, only versions whose micro or patch number (the third and last number) are zero are considered stable. Other releases where the version number is greater than zero are bugfix and maintainence releases and are considered unstable. For example, a release number of 1.42.0 is stable, while 1.42.3 is unstable.

1. Install Cyclus and Cycamore

The following methods of installation are listed in order of increasing sophistication, choose the option that best fits your needs. If you feel like none correspond to your needs please feel free to contact us using the Cyclus User mailing list, we will identify the best approach for you.

2. Run Cyclus with a Sample XML File

Try running Cyclus for yourself. The result will be a database named cyclus.sqlite. Use your favorite sqlite browser to peruse, or explore the data using Cymetric.

$ cyclus ~/path/to/cycamore/input/recycle.xml
