- 1.
Regarding 1RPVI-462C-SE, since this is an item identified in the Risk Informed In-service Inspection program, have other welds of the same material, similar environment, and similar risk category been considered as a substitute so that a 100 percent volumetric coverage can be achieved. In addition, was a surface examination performed on 1RPVI-462C-SE? What was the coverage achieved?
What were the results from previous inspections?
- 2.
For component 2N12FW26-15 (Item C05.011.168) the Code requires both volumetric and surface examinations. The submittal implied that surface examinations have been completed. What was the coverage achieved?
3.
For all other components for which 100 percent volumetric can not be achieved (e.g.,
2NCW-3673-1, 2NC2FW22-6), please state if surface examination has been performed, and the coverage achieved. Similarly, for components for which 100 percent surface can not be achieved (e.g. 1CCPUMP-1A), although not required by the Code, please state if volumetric examination has been considered as an alternative to supplement the coverage of surface examination.
