NOTE 9 - Item Number E4.11 The DAEC has evaluated the need for augmented examination per this item number and has determined that the Torus should be examined twice per interval. Details are specified in Technical Approach and Position TAP-E002.

NOTE 10 - Item Number E9.20 There are no components identified under this item number because the DAEC has been approved to use Option B of Appendix J. The "Performance Based Containment Testing Program" contains the requirements.

NOTE 11 - Item Numbers B5.XX, B9XX, C5MXX, and R-I Risk-Informed methods are utilized as described in EPRI TR-1 12657B-A to determine scope of inspections for examination categories B-F, B-J, and C-F-2. The Risk-Informed scope has been combined into a new item number R-I for implementation in the second and third periods of the third interval.
