Enclosure ST. LUCIE UNITS 1 AND 2 LICENSE RENEWAL APPLICATION The staff of the U.S. Nuclear Regulatory Commission (NRC) held a telephone conference with the applicant on May 9, 2003, to discuss the applicants supplemental response to the staffs request for additional information 2.1-2 contained in a letter dated September 26, 2002. During the teleconference, the staff requested clarification of the applicants supplement response concerning aging management of the nonsegregated-phase bus. The staff requests that the applicant provide a schedule for submitting its clarification within 30 days of the receipt of this request.
Requested Clarification to Supplemental Response to RAI 2.1-1 1.
Industry experience (i.e., IN 89-64) indicates that the potential exists for Noryl-insulated medium-voltage bus bars to experience catastrophic failure if they are not periodically inspected and maintained. Failures have occurred at the Palo Verde, Kewaunne, Millstone, and Sequoyah plants. If bus bars at St. Lucie are insulated, then explain why failure of insulated bus bars are not a concern at St. Lucie.
2.
Describe the design of the non-segregated bus duct system at St. Lucie and explain why accumulation of water, dust, or debris is not a concern, as indicated in IN 89-64.
Are there any ventilation openings in the bus ducts? If there are no ventilation openings, then explain how the bus duct is cooled. If there are openings, can moisture, dust, or debris get into the ventilation openings?
3.
During the May 9, 2003 conference call between the staff and the applicant, the applicant indicated that it will revise the Table 2.1-7 and Table 2.1-8 of the September 26, 2002, response to include the non-segregated bus ducts in the System and Structures Monitoring Program. How does the program inspect the waterproofing material (i.e., seals) for the non-segregated phase bus ducts?
