SUMMARY

OF TELEPHONE CONFERENCE FOR CLARIFICATION OF ONE PORTION OF THE RESPONSE TO PERTAINING TO THE SOUTH TEXAS PROJECT, UNITS 1 AND LICENSE RENEWAL August 9, The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of South Texas Project Nuclear Operating Company (STPNOC or the applicant) held a telephone conference call on August 9, 2012, to discuss clarification of one portion of the applicant's response to Request for Additional Information (RAI) 4.3-13, for the South Texas Project, Units 1 and 2, license renewal application (LRA). The telephone conference call was useful in clarifying the response to the RAI. Discussion The staff noted that the applicant, in its response to RAI 4.3-13 by letter dated November 21, 2011, stated concerning Transient 11 and its associated stress fatigue: " ... Transient 11 number of cycles is beyond the endurance limit of the ASME fatigue curves ... " (page 41 of 103) When compared to the American Society of Mechanical Engineers (ASME) fatigue curve, the staff was unable to determine the meaning of the applicant's statement.

The staff and the applicant discussed this in order for the staff to obtain clarification as to the applicant's intended response.

The applicant stated that the intent of the statement was to read as follows: liThe stress range of Transient 11 is below the endurance limit of the ASME fatigue curves, therefore this transient is not significant to fatigue." The applicant also stated that it did not believe that the LRA required changing because table 4.3.2 lists the transient and the current footnote for transient 11 in Table 4.3.2 appeared to be adequate.

The staff agreed to this position.

The staff agreed with the clarification and stated that it would reference this record of conference call, as necessary, in its evaluation of the issue for the Safety Evaluation with Open Items. ENCLOSURE September 12, 2012 LICENSEE:
