Paper No: ICONE29-88944
... Abstract The cladding of the fuel rod is a cylinder-shaped structure made of Zirconium alloy, which will collapse due to structural creep under the extremely service conditions such as high temperature, high pressure, and high irradiation. The collapse of the cladding results in losing its...

... Abstract Reactivity-initiated accident (RIA) is postulated design-basis accidents (DBAs) in light-water reactor (LWR). Moreover, Pellet-cladding mechanical interaction (PCMI) can cause a failure of the cladding in the early transient. In recent RIA regulatory guide released by NRC which points...

... operation. Therefore, this paper proposed a novel Dual-Cladding design concept to decrease the probability of cladding failure and increase the accident-tolerance ability of fuel rods in 200MW Nuclear Heating Reactor II (NHR200-II). Compared to the single cladding of conventional PWR fuel, the Dual-Cladding...

... calculation results are presented in the paper. The processes are investigated for the first phase of severe accidents covering the period from the onset of fuel-rod melting to the melt escape from the core center.

...Abstract Abstract Pellet-Cladding Mechanical Interaction (PCMI) failure is the one of failure mode which must be evaluated in the nuclear fuel safety. PCMI is caused by the mechanical load to cladding due to the fuel pellet expansion. Under the high fuel burnup condition, the fuel cladding may...
