3.0 BACKGROUND
This change is to update the San Onofre Units 2 and 3 Technical Specifications to be consistent with NUREG-1432, Revision 3, "Standard Technical Specifications for Combustion Engineering (CE) Plants" (Reference 1), based on the following NRC approved Technical Specification Task Force (TSTF) travelers (References 2 through 5):
- a. TSTF-9 Relocate the TS 3.1.1 and 3.1.2 numerical shutdown margin requirements to the COLR. Note that TSTF-9 and TSTF-67 affect some of the same Technical Specification items. In these cases, the revised text has been based on the more recent TSTF-67.
- b. TSTF-67 Update the TS 1.1 definition of shutdown margin, and remove the requirement to verify SDM from TSs 3.1.5, 3.1.6, and 3.1.7.
Note that TSTF-67 includes changes to the Section 3.1 Special Test Exceptions (STE). These STE changes are not applicable to SONGS, due to the wording used in the SONGS STE. Also note that some of the TSTF-67 changes superseded the changes made by TSTF-9.
- c. TSTF-142 Increase the TS 3.1.3 required action completion time from 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to 7 days when the core reactivity balance is not in agreement with the predicted values.
- d. TSTF-150 Relocate to the COLR the TS 3.2.4 power margin that must be accommodated when COLSS is in service and neither CEA Calculator (CEAC) is OPERABLE.
The following Table compares the proposed wording to the wording in both the TSTF item and the current Standard Technical Specifications (NUREG-1432, Rev. 3, Reference 1).

specifically described in the TSTFs that relocate items to the COLR.
4.0 TECHNICAL ANALYSIS
TS 1.1 As described and approved inTSTF-67 (Reference 3), the current definition of "SHUTDOWN MARGIN" is incorrect. Specifically, paragraph b. of the definition states "InMODES 1 and 2, the fuel and moderator temperatures are changed to the corrected hot zero power condition." Under the Combustion Engineering (CE) core design methodology, the changes infuel and moderator temperatures are included inthe determination of the Control Element Assembly (CEA) Power Dependent Insertion Limit (PDIL), which is used to ensure adequate shutdown margin in MODES 1 and 2. The requirements on CEAs are given in paragraphs a., c., and the last paragraph of the current TS 1.1 SHUTDOWN MARGIN definition. As documented in the NRC approved SONGS reload analysis methodology (Reference 6), SONGS uses the CE core design methodology. Therefore, TSTF-67 is applicable to SONGS. The proposed wording and format are identical to NUREG-1432, Rev. 3, Section 1.1.
TSs 3.1.1 and 3.1.2 Relocating the cycle dependent Shutdown Margin to the COLR is consistent with NRC approved TSTF-9 (Reference 2). The Limiting Conditions of Operation (LCOs) and COLR will continue to ensure that adequate shutdown margin is maintained. Appropriate analyses will continue to be performed in accordance with NRC approved SONGS reload analysis methodology (Reference 6) to ensure that all design basis events have acceptable results.
The proposed wording is identical to NUREG-1432, Rev. 3, Specification 3.1.1.
(Note that the SONGS Technical Specifications split the SDM specification into a high and low temperature specification, while NUREG-1 432, Rev. 3 has a single specification that applies to all temperatures. Separate SDM specifications for high and low temperatures are maintained to minimize the impact on existing plant procedures.)
TS 3.1.3 Increasing the required Completion Time from 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to 7 days is consistent with NRC approved TSTF-142 (Reference 4). The Actions when core reactivity balance is not within the limit require a reevaluation of core design and safety analysis, determination ifthe reactor core isacceptable for continued operation, and the establishment of appropriate operating restrictions and SRs within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
Evaluating a predicted versus measured reactivity anomaly is very complex. Data would need to be gathered, evaluated, and appropriate controls put in place based on the data. If Boron-1 0 depletion may be a contributing factor, an RCS sample would likely be drawn and sent to an offsite laboratory for analysis. It would be difficult to complete all of these actions in72 hours. Itis important to allow sufficient time to properly analyze the causes of a reactivity anomaly. The proposed 7-day period is sufficient time to properly analyze the causes. The proposed 7-day Completion Time is acceptable because of the conservatisms used in designing the reactor core and performing the safety analyses, and the low probability of a design basis accident or anticipated transient approaching the core design limits occurring during the 7-day period. The proposed wording is identical to NUREG-1432, Rev.3, Specification 3.1.2.
TS 3.1.5 Removing the requirements to verify shutdown margin and initiate boration is consistent with NRC approved TSTF-67 (Reference 3). Per the discussion for TS 1.1, for plants using the CE core design methodology, the assurance of shutdown margin in Modes 1 and 2 is based solely on CEAs. When CEAs are inoperable, calculating Shutdown Margin, as required in many Actions, is inappropriate for CE plants. Specifically, CEA alignment and insertion specifications that have Actions that require verification of Shutdown Margin and, if needed, boration, are incorrect for CE plants. If the CEAs are above the PDIL, there is adequate Shutdown Margin. If not, restoring the CEAs to within their limits will restore the Shutdown Margin. Under the CE core design methodology, boration is not an appropriate action to restore shutdown margin. As documented in the NRC approved SONGS reload analysis methodology (Reference 6), SONGS uses the CE core design methodology.
Therefore, TSTF-67 is applicable to SONGS.
The proposed wording has minor differences with NUREG-1 432, Rev. 3, Specification 3.1.4, due to minor differences in the current SONGS licensing basis. The current SONGS TSs include separate conditions for each type of CEA (regulating, shutdown, and part-length), while NUREG-1 432 has a single condition that applies to all CEAs. Additionally, the SONGS specific alignment criteria differ from the generic criteria in NUREG-1432. The SONGS TSs also require any misaligned regulating or shutdown CEA to be trippable. Additionally, NUREG-1432 Figure 3.1.4-1 contains the power reduction requirements, while at SONGS the power reduction requirements have already been relocated to the SONGS COLR. The SONGS TSs require initiation of the power reduction within 15 minutes, with the completion time as specified in the COLR. NUREG-1432 does not specify a starting time for the initiation of the power reduction, and specifies a completion time of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.
TSs 3.1.6 and 3.1.7 Removing the requirements to verify shutdown margin and initiate boration is consistent with NRC approved TSTF-67 (Reference 3). Per the discussion forTS 1.1, for plants using the CE core design methodology, the assurance of shutdown margin in Modes 1 and 2 is based solely on CEAs. When CEAs are inoperable, calculating Shutdown Margin, as required in many Actions, is inappropriate for CE plants. Specifically, CEA alignment and insertion specifications that have Actions that require verification of Shutdown Margin and, if needed, boration, are incorrect for CE plants. If the CEAs are above the PDIL, there is adequate Shutdown Margin. If not, restoring the CEAs to within their limits will restore the Shutdown Margin. Under the CE core design methodology, boration is not an appropriate action to restore shutdown margin. As documented inthe NRC approved SONGS reload analysis methodology (Reference 6), SONGS uses the CE core design methodology. Therefore, TSTF-67 isapplicable to SONGS. The proposed wording is consistent with NUREG-1432, Rev. 3,Specifications 3.1.5 and 3.1.6.
TS 3.2.4 Relocating the numerical value for decreasing the COLSS core power operating limit based on DNBR when COLSS is in service and neither CEAC is OPERABLE is consistent with NRC approved TSTF-150 (Reference 5).
Limiting Condition of Operation (LCO) 3.2.4.b requires that the COLSS core power operating limit based on DNBR be decreased by 13% rated thermal power (RTP) when COLSS is in service and neither CEAC is OPERABLE. This specific value is replaced with a reference to the COLR. The decrease in the power operating limit based on DNBR is a cycle-specific value. Therefore, this information fits the criteria for relocation to the COLR. Relocating the numerical value for decreasing the COLSS core power operating limit based on DNBR to the COLR is acceptable because the LCOs and COLR will continue to ensure that the appropriate COLSS penalty value is maintained during plant operation.
Appropriate analyses will continue to be performed in accordance with the NRC approved SONGS reload analysis methodology (Reference 6) to ensure that all design basis events have acceptable results. The proposed wording is identical to NUREG-1432, Rev. 3, Specification 3.2.4.
TS 5.7.1.5 The change to this specification is administrative in nature, as it merely adds Specifications 3.1.1 and 3.1.2 to the list of specifications which have their limits specified in the COLR (note that Specification 3.2.4 is already listed inTS 5.7.1.5).
5.0 REGULATORY SAFETY ANALYSIS 5.1 No Significant Hazards Consideration Southern California Edison (SCE) has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
- 1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No.
The Limiting Conditions of Operation (LCOs) and Core Operating Limits Report (COLR) will continue to restrict operation to within the regions that provide acceptable results. The safety analysis will continue to be performed in accordance with the Nuclear Regulatory Commission (NRC) approved San Onofre Units 2 and 3 reload analysis methodology.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No.
The proposed change does not add any new equipment, modify any interfaces with any existing equipment, alter the equipment's function, or change the method of operating the equipment. The proposed change does not alter plant conditions in a manner that could affect other plant components. The proposed change does not cause any existing equipment to become an accident initiator.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. Does the proposed change involve a significant reduction in a margin of safety?
Response: No.
Safety Limits ensure that Specified Acceptable Fuel Design Limits are not exceeded during steady state operation, normal operational transients, and anticipated operational occurrences. All fuel limits and design criteria will continue to be met, based on the NRC approved San Onofre Units 2 and 3 reload analysis methodology. Therefore, the proposed change will have no impact on the margins as defined in the Technical Specification bases.
Therefore, this change does not involve a significant reduction in a margin of safety.
Based on the above, SCE concludes that the proposed, amendment presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.
5.2 Applicable Regulatory Requirements/Criteria The request to relocate the proposed values of cycle specific parameters to the COLR is based on the Nuclear Regulatory Commission (NRC) Generic Letter (GL) 88-16, uRemoval of Cycle-Specific Parameter Limits From Technical Specifications." The conditions of GL 88-16 are met as follows: 1) The COLR is defined in Technical Specification (TS) 5.7.1.5 and the COLR includes the values of cycle-specific parameter limits that have been established using an NRC-approved methodology and consistent with all applicable limits of the safety analysis, 2) An administrative reporting requirement to submit the COLR (including cycle-specific parameter limits) to the NRC for information is in TS 5.7.1.5.d, and 3) The individual TSs (TS 3.1.1 SHUTDOWN MARGIN (SDM) -
Tavg > 2000F, TS 3.1.2 SHUTDOWN MARGIN (SDM) -Tavg < 2000F, and TS 3.2.4 for Departure From Nucleate Boiling Ratio) are being modified to note that cycle specific parameters shall be maintained within the limits provided in the COLR.
The proposed changes are consistent with NUREG 1432, Revision 3, "Standard Technical Specifications for Combustion Engineering Plants," and with Technical Specification Task Force (TSTF) Change Travelers as follows:
The proposed revisions to TS 1.1 Definitions to correct the definition of shutdown margin (SDM) and the proposed revisions to TS 3.1.5 Control Element Assembly (CEA) Alignment, TS 3.1.6 Shutdown Control Element Assembly (CEA) Insertion Limits, and TS 3.1.7 Regulating CEA Insertion Limits, to delete the requirements to verify shutdown margin and initiate boration are based on TSTF-67-A, Revision 0, "Correction of Shutdown Margin Definition."
The proposed revisions to relocate cycle specific values to the COLR in TS 3.1.1' SHUTDOWN MARGIN (SDM) -Tavg > 2000 Fand TS 3.1.2 SHUTDOWN MARGIN (SDM) -Tavg < 2000F, and TS 3.2.4 Departure From Nucleate Boiling Ratio (DNBR) are based on TSTF-9-A, Revision 1, "Relocate value for shutdown margin to COLR." The proposed revisions to relocate the cycle specific value to the COLR in TS 3.2.4 Departure From Nucleate Boiling Ratio (DNBR) is based on TSTF-1 50-A, Revision 0, "Replace DNBR Power Decrease Number with Reference to the COLR." The COLR process reduces the burden on the licensees and the NRC from processing changes to cycle-specific parameter limits in TSs for each fuel cycle, provided the limits are developed using an NRC-approved methodology. The NRC-approved methodology for calculation of SDM and the DNBR Power Decrease Number is SCE-9801-P-A, "Reload Analysis Methodology for the San Onofre Nuclear Generating Station Units 2 and 3" (Reference 6).
The proposed revision to TS 3.1.3 Reactivity Balance to increase the required action time from 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to 7 days when the core reactivity balance is not in agreement with the predicted values is based on TSTF-142-A, Revision 0, "Increase the Completion Time When the Core Reactivity Balance is Not Within Limit."
6.0 PRECEDENCE
- 1. By letter dated September 25, 2003 the NRC issued Amendment No. 280 to Facility Operating License No. DPR-65, approving a request by submittal dated August 14, 2002, as supplemented on March 11, May 16, and May 23, 2003, from Dominion Nuclear Connecticut, Inc. for Millstone Power Station, Unit No. 2. This amendment implemented TSTF-67 to delete the requirement to verify shutdown margin upon determination of inoperable or misaligned CEAs. This amendment also implemented TSTF-142 to increase the Completion Time from 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to 7 days to re-evaluate the core design and safety analysis if the reactor core reactivity balance is not within the limit.
- 2. By a letter dated March 9, 2004 the NRC issued Amendment No. 218 to Facility Operating License No. NPF-49, approving a request by submittals dated April 7, 2003 and September 18, 2003 from Dominion Nuclear Connecticut, Inc. for Millstone Power Station, Unit No. 3 implemented TSTF-9 to relocate some Technical Specification parameters to the COLR.
- 3. By letter dated March 23, 2004 the NRC issued Amendment No. 96 to the Seabrook Facility Operating License No. NPF-86, approving a request from North Atlantic Energy Service Corporation for Seabrook Station, Unit 1, dated April 15, 2002, to relocate cycle-specific Technical Specification parameters to the COLR.
- 4. NUREG-1432, Revision 3, "Standard Technical Specifications for Combustion Engineering Plants."
- 5. TSTF-9-A, Revision 1, "Relocate value for shutdown margin to COLR.'
- 6. TSTF-67-A, Revision 0, "Correction of Shutdown Margin Definition."
- 7. TSTF-1 42-A, Revision 0, "Increase the Completion Time When the Core Reactivity Balance is Not Within Limit."
7.0 ENVIRONMENTAL CONSIDERATION
A review has determined that the proposed amendments would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendments do not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendments meet the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environment impact statement or environmental assessment need be prepared in connection with these proposed amendments.
