facility acceptable excursion limit (FAEL): the distance a load can move where its movement remains safe. This limit applies to any hoist or travel motion when uncommanded load movement occurs. It is intended to assume a mechanical or a control system failure has occurred and manual or automatic systems must be used to stop the load.
infrequently performed test and evolution (IPTE): infrequently performed test or evolution that has the potential to significantly degrade the plant’s margin of safety and therefore warrants additional management oversight and control.
intermediate hoist an additional hoist that is used as part of the rigging below the primary hoist. It could be used as a means of leveling the load or as a more precise means of lifting the load.
lift, critical: any lift that carries a high risk of a load-handling event, as determined by the presenceof certain probability factors and the severity of the possible consequences of such an event.
lift nuclear safety critical: any lift, performed in a given area after a plant becomes operational, In which the load weighs more than the combined weight of a single spent fuel assembly and its associated handling tool for the specific plant in question that, as a result of uncontrolled motion exceeding the movement safety envelope, can result In the loss of an essential safety function. Nuclear safety critical lifts are a subset of critical lifts.
lift; special: any lift that carries a moderate risk of a load- handling event, as determined by the presence of certain probability factors and the severity of the possible consequences of such an event.
lift, standard: any lift that carnes a low risk of a load-handling event, as determined by the presenceof certain probability factors and the severity of the possible consequences of such an event.
lifting evolution: the lifting, transporting, and setting down of any load. Lifting and setting down the load in the same location for a rigging adjustment does not constitute a lilting evolution.
load-handling event an unplanned and undesirable occurrence during the movement of a crane or its load that may have a negative effect on operations.ASME NML-1 pdf download.
