Nondestructive postirradiation examinations using cold neutron radiography technology were conducted to check fuel cladding integrity and swelling behavior.
In order to meet clean core challenges in Sodium-Cooled Fast Reactors SFRR), specific attention is paid to the cladding integrity.
Analyses are concentrated on the circumferential temperature distribution on the cladding outer surface because the Maximum Cladding Surface Temperature (MCST) has been a crucial design parameter to evaluate fuel cladding integrity of the Super Fast Reactor.
These materials are intended to improve core fuel and cladding integrity under beyond design basis accident conditions while maintaining or enhancing reactor performance and safety characteristics during normal operation.
In the present paper cladding integrity is tried to be kept by employing recladding and the core height is tried to be shorten by employing multi-channel once-through-then-out (MOTTO) cycle.
Loss of coolant or enduring loss of cooling conditions would ultimately result in loss of cladding integrity at elevated temperatures with excessive release of fission products and hydrogen.

Fuel and cladding integrities, and flow-induced vibration were taken into account as design criteria.
The body of work that John McCabe leaves to the world, after his death last Friday at the age of 75, is music of iron-clad integrity.
In most cases, the flow inversion phenomenon is accompanied by boiling which is undesirable phenomenon in this type of reactors as it could affect the fuel-clad integrity.
However, when CANDLE is extended to long life, the clad integrity at high neutron fluence, the build-up of fission product gases, and the pressure drop for long cores pose technological challenges which have to be overcome.
In this paper, we propose practically viable design procedures, such as recladding the entire fuel pins and replacement of different amounts of fuel at different radial positions, to ensure clad integrity and flat power distribution, respectively.
