Which of the following statements is correct with regard to the results of quantitative analy-
sis?
A They normally provide an initial screening with which to rank units for attention.
B They are usually numeric and should be comparable
C They must be included in the documentation of any RBI evaluation
D They are more accurate that the results of a qualitative analysis.
ANSWER
B
Which of the following statements is correct with regard to equipment items with risks
deemed acceptable by RBI analysis?

B Inspection effectiveness should be adjusted
C Equipment should be removed from inspection programs
D No further mitigation is necessary
ANSWER
D
In RBI, residual factors for loss of containment include all of the following except:
A Human Error
B Unknown mechanisms of deterioration
1
,C Inspection efforts
D Secondary effects from nearby units.
ANSWER
C
Compared to quantitative analysis, qualitative analysis using broad ranges generally re-
quires:
A a lower level of judgement, skill, and understanding.
B Greater accuracy in data input to compensate for lower precision of the models
C Higher level of judgment, skill, and understanding
D Better training in understanding the impact of data quality
ANSWER
C
In RBI investigation, consequence analysis is intended to provide a measure of the:
A Mitigations necessary to reduce risk.
B Overall risk of a potential failure
C Maximum liability for a failure
D Significance of a potential failure.
ANSWER
D
Risk reduction is:
A Synonymous with risk management
B Synonymous with inspection optimization
2
, C Part of risk management

ANSWER
C
RBI contributes to reduction of overall life-cycle costs by:
A using less expensive inspection techniques
B Increasing the number of internal inspections
C Increasing the number of non-intrusive inspections.
D Enhancing the prediction of failure caused by deterioration mechanisms
ANSWER
D
The value of a qualitative approach is that:
A the risk assessment process is much faster
B It uses logic models that depict combinations of events
C It enables completion of a risk assessment in the absence of detailed data.
D It produces relative risk numbers rather than absolute risk numbers.
