1
Q

Risk is assessed by identifying credible damage mechanisms, estimating the POFs, assessing the COFs, and
identifying the risk drivers to enable development of effective risk mitigation strategies

Q

Effective risk assessment should be a rational, logical, structured process that contains at least two key steps:
1) determine how significant the risk is, and
2) determine whether the risk is acceptable.

Q

Key elements that exist in any RBI program include the following:

A

a) management systems for maintaining documentation, personnel qualifications, data requirements, consistency of
the program, and analysis update.
b) documented method for POF determination.
c) documented method for COF determination.
d) management systems for maintaining documentation, personnel qualifications, data requirements, consistency of
documented methodology for managing risk through inspection, process control, and other mitigation activities

Q

. Accuracy
is a function of the analysis methodology, the quality of the data, and consistency of application, while precision is a
function of the selected metrics and computational methods.

Q

Quantitative analysis uses logic models to calculate probabilities and consequences of failure. Logic models used to
characterize materials damage of equipment and to determine the COF can have significant variability and therefore
can introduce error and inaccuracy that impacts the quality of the risk assessment. It is important that results from
these logic models are validated by expert judgment
