SCB interruption capability

Q.
(Lot 2)
Concerning § 7.2.2 of the Technical Specification (Factory Type Test on SCB):
"4) Test to verify the current interruption capability of the SCB":
Although the current of 47 kA is actually about 10% higher than the nominal FDU current, if Non-linear Dump Resistors are used the reapplied max voltage might result lower than indicated (Vnom +10%). Is this acceptable?
Regarding the interval of 30 minutes: this is ½ of the nominal repetition rate. This procedure, adds to the increase in the current and might bring to unwanted thermal build up, in a structure designed to operate every 60 minutes. May this interval be exactly defined during DDP?

1) For the former question: Yes it is acceptable.
2) For the last one: Yes as I said: we can discuss this point in a deeper way during DDP.
