In order to clarify the air oxidation behavior of the cladding at high temperatures for study on improvement of safety for accident conditions in spent fuel pool, the oxidation tests for both small specimens under constant temperature conditions and long specimens under loss of coolant simulated temperature conditions were carried out, and the knowledge for influence of both temperature gradient and preoxide film on oxidation behavior of the cladding were obtained in this study.

For the upgrading of the severe accident code aiming to analyze the coolant loss accident in spent fuel pool (SFP), it is required to model the air oxidation behavior of the cladding at high temperature. Authors proceeded air oxidation tests using small samples and long samples. For the long samples, temperature distribution simulating the SFP accident condition was given. The results were evaluated for the construction and validation of the air oxidation model. The results of the experiments and the outline of the program will be presented as well.
