What is the difference between destabilizing load and normal load?

The common definition of a destabilising load is if the load is free to move with the flange, it's a destabilising load. The stress due to the lateral bending of the flange is increased, which means the beam is closer to buckling than it would be without the additional moment.

Something that is normal is usual and ordinary, and is what people expect.The leakage crack is a postulated crack that, under normal operating loads (pressure, weight, thermal expansion), will discharge a detectable amount of fluid.

The leak rates are calculated based on the flaw geometry, the applied loads, and the crack morphology. The crack opening displacement and crack morphology are typically based on two cases: (1) a fatigue-induced transgranular crack and (2) a corrosion-induced intergranular crack. The leak flow through a crack must be analyzed with the correct thermohydraulic model that captures, as the fluid progresses from the inner diameter (ID) to the outer diameter (OD), a subcooled phase (pressurized hot water) at the ID entrance into the crack, a steam formation phase somewhere between the ID and the OD, and then a two-phase flow region toward the OD, and discharge into the containment environment.
