“…Many in-pile experiments [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] related to failure propagation after fuel ejection have been performed. The main experimental conditions and results of these in-pile tests are summarized in Table 5 based on a broad review of open papers.…”

Experimental studies on local fault (LF) accidents in fast breeder reactors have been performed in many countries because LFs have been historically considered as one of the possible causes of severe accidents. Comprehensive and consistent interpretations of in-pile and out-of-pile experiments related to LF were arrived at in this study based on state-of-the-art review and data analysis techniques. Safety margins for a hypothetical local overpower accident, which was evaluated as a LF accident in the licensing document of the construction permit for a prototype fast breeder reactor called Monju, were also studied. Based on comprehensive interpretations of the latest experimental database, including those performed after the permission of Monju construction, it was clarified that the evaluation of the hypothetical local overpower accident in the Monju licensing was sufficiently conservative. Furthermore, it incorporated adequate safety margins in terms of failure thresholds of the fuel pin, molten fuel ejection, fuel sweep-out behavior after molten fuel ejection, and pin-to-pin failure propagation. Moreover, these comprehensive interpretations are valid and applicable to the safety evaluation of LF accidents of other fast breeder reactors with various fuel and core designs.

“…To investigate the problems outlined above an experimental program called "Mol7C" was carried out in the IPSL (In Pile Sodium Loop) in the BR2 reactor at Mol/Belgium by KfK Karlsruhe and SCK/CEN Mol with the support of JRC Ispra(T) (8). The test sections contained small fuel pin bundles with a porous local blockage simulating the local cooling disturbances.…”

The main objective of the experiments Mol 7C/3 to 6 was to investigate the role of burnup in the propagation of local faults in LMH fuel subassemblies. The test sections contained bundles of 30 fuel pins with burn-ups between 0.3 and l o a t % and porous blockages as local fault initiators. The main result of the experiments is that with rising burn-up there is an increasing potential for damage progression from the blockage to the surrounding bundle and structures. Only a t low burn-up, faults of the kind and type investigated are self-limiting. A t medium and high burn-ups, active protection systems, in particular the delayed neutron detection system, are required to prevent whole core involvement.
