I don't agree with your statement. I stood in that control room for every test of the commissioning, through the low power and the high power tests. The reactor behaved extremely well. It was very stable. As Dr. Meneley pointed out, when a coefficient is small, it doesn't really matter.
The thing is, we have extremely conservative safety cases that say there isn't a problem. And when I say “extremely conservative“, we have essentially three shut-down systems. Two of them are fast, less than one second for insertion, and the other one takes two and a half seconds. We are forced by the regulatory process to credit only the very slow one. That's a point of difference between MAPLE and HANARO. HANARO does not have the slow system. Their regulator did not require them to put it in. They have only the two fast ones. When you can credit one of the fast systems, there is no safety issue. In fact, even with the slow system we can still make the safety case.
