The work reported was primarily aimed at establishing minimum requirements for and likelihood of large-scale voiding following fuel-pin-failure in an unprotected transient overpower (TOP) accident in a liquid-metal-cooled fast breeder reactor (LMFBR). Some attention was also given to voiding following pin failure in the low power channels of an LMFBR during the loss-of-flow-driven TOP. Initial work on early fuel motion out the pin and into sodium for both types of TOP accidents is also discussed.
