SUMMARY
OF HEADQUARTERS AND SOUTH TEXAS PROJECT NUCLEAR OPERATING COMPANY TELEPHONE CONFERENCE CALL OF JULY 2, 2003, REGARDING STAFF REVIEW ISSUES WITH THE SOUTH TEXAS PROJECT PROPOSED RISK-INFORMED INSERVICE TESTING PROGRAM (TAC NOS. MB8948 AND MB8949)
On July 2, 2003, the U. S. Nuclear Regulatory Commission (NRC) Headquarters staff held a telephone conference call with STP Nuclear Operating Company (STPNOC), the licensee for South Texas Project (STP), Units 1 and 2. The purpose of the telephone conference call was to discuss the proposed Risk-Informed Inservice Testing (RI-IST) program submittal. The staff had previously transmitted 6 technical issues concerning the RI-IST submittal to STP on May 29, 2003 (ADAMS ML031490352). To support the July 2, 2003, discussions STP had provided the staff with some brief responses to the NRCs technical issues along with a matrix depicting the relationship of the proposed RI-IST change with respect to the previously approved special treatment exemption (Enclosure 1). A list of participants is enclosed as Enclosure 2.
During the call, STP provided clarifying and amplifying information about their proposed RI-IST program in response to the staffs concerns.
STP agreed that they could have done a better job documenting why their proposed RI-IST ranking for components differed from the special treatment exemption ranking. STP said they felt they could document the basis for these differences to the staffs satisfaction. The staff suggested that STP not start this substantive effort until after the staff makes a decision on the proposed RI-IST categorization approach.
The telephone conference call ended with STP and NRC staff indicating that they understood each others positions on the issues and that the NRC staff would discuss the viability of the STP proposed categorization approach with NRR management. The staff agreed to get back to STP on their proposed categorization approach as soon as practical. The STP personnel
also indicated they would further consider the NRC comments with respect to their proposed RI-IST methodology. Both parties agreed to have a follow-up discussion after the requisite internal interactions have been held.

NRC Staffs Issues with STPNOCs Proposed RI-IST Program STP has reviewed the NRC staff feedback on the subject submittal, and believes that additional clarification is needed on each of the identified issues as stated below:
Issue 1 - RI-IST will recategorize SSCs
RI-IST does not recategorize SSCs - SSCs remain categorized as per the STP Exemption
RI-IST does not affect program scope - RI-IST merely identifies appropriate treatment strategies for scoped SSCs
Reg Guides 1.174 and 1.175, as well as OMN-3 guidance, were followed to determine the appropriate treatment strategies Issue 2 - Proposed RI-IST and the STP Exemption impacts must be considered together
The STP Exemption and the proposed RI-IST are separate issues - the Exemption determined the scope of SSCs in the IST Program, while RI-IST determines the treatment strategy for those SSCs remaining in the IST scope
The sensitivity studies used to demonstrate the acceptability of the STP Exemption approach remain bounding for the proposed RI-IST Issue 3 - Proposed RI-IST does not properly address passive functions
Certain SSCs are categorized as HIGH/MEDIUM due to pressure boundary considerations only - these SSCs do not require pressure boundary testing under either IST or proposed RI-IST
In the PRA, passive refers to an SSC performing its function without changing state
SSC repositioning after an event is an active function - the PRA specifically models off-normal states and the recovery actions as applicable
RI-IST will test all safety functions as required by the Code Issue 4 - RI-IST will not properly test scoped components
Per the approved STP Exemption, SSCs categorized as LOW/NRS are removed from the scope of IST - LOW/NRS SSCs are not within the scope of the RI-IST request
RI-IST merely applies treatment strategies for scoped SSCs consistent with RG1.175
Per RG1.175, staggered testing of valve groups is permitted - test interval is no greater than the number of valves in a group x 18 months - we will not exceed a test interval of 6 years
The STP proposal is consistent with RI-IST programs already approved for Comanche Peak and San Onofre ENCLOSURE 1
Issue 5 - HSS/MSS SSCs must be evaluated for enhanced treatment
Per the STP Exemption, Box 2 SSCs must be evaluated for enhanced treatment
- there are no Box 2 SSCs in the existing IST Program or in the proposed RI-IST Program
During the categorization process (which is not part of this RI-IST request), Box 1 SSCs are evaluated for enhanced treatment only if beyond design basis functions are identified
STP has chosen to add certain safety significant SSCs into the RI-IST program which are not scoped in the existing IST Program - these new SSCs will be trended as part of their treatment Issue 6 - Common cause is not properly addressed in the proposed RI-IST
STPs approach to common cause is extremely conservative - if we were to apply a common cause approach similar to already-approved RI-IST programs, a significant number of STPs SSCs would migrate from a more robust treatment approach to a more relaxed treatment approach
ASME PRA standard (DG-1122) does not require modeling of inter-system common cause
STPs cultural approach to potential common cause issues is both a strength and is conservative, as highlighted by the recent MOV issue - following 100%
inspection by STP, only the initial identified deficiency could have affected component functionality
