9.2.1 The basic evaluation approach

The basic evaluation approach developed by the Generation IV International Forum’s (GIF) Working Group on Proliferation Resistance and Physical Protection comprises definition of a set of threats or challenges, evaluation of the system’s response to these challenges, and expression of outcomes in terms of measures.

A progressive approach permits broad application of the PR&PP evaluation to SMRs. SMRs assessed for PR&PP can range from systems under development to fully designed and operating systems. The scope and complexity of the assessment should be appropriate to the level of detailed design information available and the level of detail with which the threats can be specified.

The main steps to be performed in each component of the approach are illustrated in Figure 9.2 and discussed in the following sections.
