In the Onagawa Nuclear Power Station Units 1 and 3, it was confirmed that the spent fuel pool (hereinafter referred to as pool) water temperature converged to a certain temperature even when there is no cooling of the pool.

In addition, it was confirmed that the convergence temperature is well below the operating limit set by the safety regulations in the current fuel storage condition during long-term shutdown of the plant.

Furthermore, it was confirmed that the evaluation results from the newly constructed pool water temperature evaluation model were in good agreement with the measurement results.
