1 the tendon containing 6 broken wires) shall be inspected.
The acceptance criterion then shall be no more than 4 broken wires in any of the additional 4
tendons.
If this criterion is not satisfied, all of the tendons shall be inspected and if more than 5% of the total wires are broken, the reactor shall be shut down and depressurized.
4.4.4.2 Pre-Stress Confirmation Test a ~
b ~
Lift-offtests shall be performed on the 14 tendors identified in 4.4.4.la
- above, at the intervals specified in 4.4.4.1b.
If the average stress in the 14 tendons checked is less than 144 000 psi (60% of ultimate stress), all tendons shall be checked for stress and retensioned, if necessary,
.to a stress of 144,000 psi.
Before reseating a tendon, additional stress (6%)
shall be imposed to verify the ability of the tendon to sustain the added stress applied during accident conditions.
