| On page 2 of the attachment under 3.1 it is stated that both welds were examined in the 19th refueling outage. That outage concluded in June of 2016. Do I understand correctly that the welds in question were thoroughly examined at that time? In section 3.3 are statements about ultrasonic examinations covering 63% and 52% of welds. Is the impracticality referred to in this document defined by the fact that, when in operating mode, it is impossible to access the welds in the way they can be accessed during an outage? Will the welds be inspected during future outages? If so, during what month/s would such inspections take place? | | On page 2 of the attachment under 3.1 it is stated that both welds were examined in the 19th refueling outage.

| Section 3.5 seems to be an admission that the design of the seal injection filter vessel is faulty.
