This NUREG-0471[1] task covers a spectrum of technical efforts related to the staff review of LMFBR fuel designs. The efforts include: (1) evaluating licensing requirements for the behavior of stainless steel cladding and hexcans in an LMFBR and establishing fuel damage criteria, (2) developing and maintaining a flexible and well- verified thermal performance code (GAPCON-FAST) for audit calculations, testing of separate effects models, and parametric studies, and (3) evaluating the effect of cladding attack by fission products on the mechanical properties and performance of stainless steel cladding.
This item is a Licensing Issue that has been dropped from further consideration.[2]
