The fl(AI) "negative" breakpoints and the fl(AI) "negative" slope are less restrictive than the OPAT f 2 (Al) negative breakpoint and slope. Therefore, during a transient which challenges the negative imbalance limits, the OPAT f2 (AI) limits will result in a reactor trip before the OTAT fl(AI) limits are reached. This makes implementation of the OTAT fl (AT) negative breakpoint and slope unnecessary.
