screening out
5.3.3
Qualitative assessments generally are not as repeatable as quantitative assessments. True or false?
True
5.3.3

True
5.3.4
Quantitative methods are more _____,______, and _____, and they are easier to update with inspection results than qualitative approaches.
Systematic, consistent, and documented
5.3.4

Quantitative
5.3.4
What approach uses aspects derived from both the qualitative and quantitative approaches?
Semi-quantitative
5.3.5
______ is a function of the analysis methodology, the quality of the data, and consistency of application, while ______ is a function of the selected metrics and computational methods.
Accuracy, precision
5.4
Quantitative analysis uses _________ to calculate probabilities and consequences of failure.
logic models
5.4
The ______ of any type of RBI analysis depends on using a sound methodology, quality data, and qualified personnel.
Accuracy
5.4
Since risk is dynamic, it is vital that any RBI process that is developed or selected for application have the ability to be easily updated when changes occur or new information is discovered. True or false?
True
5.5
Although inspection does not reduce risk directly, it is a risk management activity that may lead to risk reduction. True or false?
True
5.6.1
In-Service inspection is primarily concerned with the detection and monitoring of ______?
Deterioration
5.6.1
The primary product of an RBI effort should be an __________ for each equipment item evaluated.
Inspection plan
5.6.2
For risks considered to be unacceptable, the plan should contain the mitigation actions that are recommended to reduce the unmitigated risk to _________?
Acceptable levels
5.6.2
For those scope equipment items where inspection is an effective means of risk management, the plans shall describe the _____, _____, and _____ of inspection/examination recommended.
type, scope, and timing
5.6.2
Equipment nearing end of service, failure mechanisms (such as brittle fracture, fatigue) where avoidance of failure primarily depends on design and operating within a defined pressure/temperature envelope, and consequence-dominated risk are examples of what? What mitigation actions may need done?
Risk that cannot be adequately managed by inspection alone. Repair, replacement, upgrade, redesign, etc.
5.6.4
RBI is intended to complement other risk-based and safety initiatives. What are some of those?
