A computer code for the calculation of steady-state and transient, thermal-mechanical behavior of oxide fuel rods for high burnup.

Capabilities for design basis accidents such as RIA and LOCAs will be released in a future version of FAST.  Users are invited to continue to use FRAPTRAN 2.0 for design basis accidents.

FAST 1.0.1 is proudly developed under NQA-1-2017.

FAST-1.0.1 corrects a code bug where the executable itself was set to expire one year after compilation.  That logic was removed from the source code.

The same current FAST license key, FASTProduct.key, will work with FAST-1.1 and FAST-1.0.1.
