Is a risk management activity that may lead to risk reduction?
If a qra has been prepared for a process unit, the analysis can borrow extensively from this effort.
Qualitative assessment is done on the basis of
Methods that use engineering judgment and experience as the bases for the analysis of probabilities and consequences of failure
_________________curves are referred for the deterioration mechanismfor carbon and low ally steel materials.
No deterioration found in the inspection program but still failure can occur under the following conditions.
Some failures have potentially serious consequences, but if the probabilityof the incident is low, then
In the event of a leak the potential failure of an isolation valve could
Probability of failure analysis is made from
Occurrence of a particular set of circum- stances, is called an
The primary work products of the rbi assessment and management approach and implementation of rbi provides
___________is usually not the primaryobjective of a rabiassessment, but it is frequently a side effect of optimization.

The data validation step stresses the need for aknowledgeable individual.
The rbi program for environmental consequences, typically focuses
A physical condition or a release of a hazardous material that could result from componentfailure and result in human injury or death, loss or damage,or environ- mental degradation
Provides a basis for risk evaluation, riskmitigation and risk acceptance
If multiple inspections have been performed, which inspectionmay best reflect current operating conditions?
In general the probability of failure is determined by
Loss of containment is
Damage mechanisms where deterioration rates are immeasurable or unknown are
