Enclosure REQUEST FOR ADDITIONAL INFORMATION ST. LUCIE UNIT 2 REVIEW OF STEAM GENERATOR REPORTS RELATED TO SPRING 2003 STEAM GENERATOR INSPECTION 1.
Were cracks detected in any wear scars located in the U-bend region? If so, please describe the inspection findings in detail (e.g., tube identifier, flaw location, etc.). In addition, describe the corrective actions taken (e.g., inspection scope expansion, etc.)
and the basis for these corrective actions.
2.
Are wear scars located in other regions of the steam generators (e.g., tube support plates and eggcrates) inspected with a rotating probe to determine whether cracking is present at the same location? If not, how are cracks in wear scars differentiated from wear scars in these locations?
3.
Were any cracks detected in dings greater than 5 volts? If so, describe the inspection findings in detail (e.g., tube identifier, ding location, ding size, and method of flaw detection [bobbin and/or rotating probe]). In addition, describe the corrective actions taken (e.g., inspection scope expansion, etc.) and the basis for these corrective actions.
4.
Single axial indications were detected in steam generator 2B near the diagonal bars on the hot leg (DHB) (e.g., DHB + 2.09 and DHB + 1.63). Please discuss these indications in more detail, including, identifying whether they are located in the freespan, how they were detected (i.e., bobbin and/or rotating probe), the severity of these indications, whether axial flaws near a DHB has previously been identified at St. Lucie 2, other relevant details (if any) and whether an inspection scope expansion was necessary.
