Further Clarification of RAI Question 10 for Quad Cities Unit 2 Relief Request I4R19 The below text clarifies the intent of RAI Question 10 provided by my e-mail dated April 11, 2012.

10. Provide a summary of the design analysis confirming that the design of the new nozzle will not eject from the reactor vessel under design conditions and that it satisfies the requirements of the ASME Code,Section III, NB-3200 and the plants original instrument penetration design basis. For example, the original design relied on the j-groove with the weld on the reactor pressure vessel inside diameter and this repair process moves the pressure boundary weld to the outside diameter with new material for the nozzle. Does this new design adversely affect the design function of this pressure retaining component? Provide the projected date when the design analysis will be available for audit or inspection.
