Not sure how they're an expert, but they are 100% correct. A "LOCA" or a "DBA-LOCA" is NOT what happened here. A "Design Based Accident - Loss Of Coolant Accident" would be a shear in a Recirc Line. What happened here is probably a gasket or O-Ring failure. That's something totally different. Either way, its a simple fix, and no danger to the public. In fact, it's only water - you can touch it with your hands! It you have to know, I'm a long time Reactor Mechanic. Seen this before.
