Rapid growth in renewable energy (RE) is essential for achieving carbon neutrality. However, the resilience of bulk power system is decreased due to the installation of large amount of RE, and there is a possibility that the transmission accident causes disasters such as a large-scale blackout. As a result, the amount of RE is limited in order not to cause such disasters. In such a situation, nuclear power plants will be useful items to reinforce the resilience of bulk power system. In this research, we eva...

The BWR-3 steam dryer in the Quad Cities Unit 2 Nuclear Power Plant was damaged by high cycle fatigue due to acoustic-induced vibration under extended power up-rate conditions. The dryer failure was as attributed to flow-in duced acoustic resonance at the stub pipes of safety relief valves (SRVs) in the main steam lines (MSLs). The acoustic resonance was considered to be generated by interaction between the sound field and unstable shear layer s across the closed side branches with SRV stub pipes. We have ...
