The total instantaneous blockage accident study progress was summarized in the paper. The most important SCARABEE-N in-pile tests in TIB fields were reviewed, also various out-of pile backup tests. The SCARABEE BE+ group and APL group, which were directly linked to TIB scenario, were compared for the different test conditions and phenomena. Many analysis models and computer codes developed in parallel with SCARABEE program were presented, followed by using SCARABEE results for code verification and engineering practice.

To predict the accident scenario caused by the total instantaneous inlet blockage of single fuel subassembly at full power in fast reactors, a model was developed according to the SCARABEE experiments. The calculation results for the SCARABEE BE+1 experiment agree well with the experimental observation. The model was then applied to an actual reactor to predict the consequences of TIB.

In actual reactors, the cooling condition outside the hexcan-wall of blocked fuel subassembly is analogous to its counterparts in the SCARABEE BE+ experiments. The upward and downward heat transfer could be neglected, while the radial heat transfer plays a key role in slowdown the accident scenario. As time goes on, the dominant radial heat transfer mechanism is liquidus sodium convection at first, and then gradually transforms into sodium condensation near the inner surface of the hexcan-wall, and finally becomes volume heated boiling pool convection.
