1. Summary Description Southern Nuclear Operating Company (SNC) proposes to revise the Joseph M.

Farley Nuclear Plant (FNP) Unit 1 and Unit 2 Technical Specifications (TS). The proposed amendment would modify Technical Specification (TS) Umiting Condition for Operation (LCO) 3.3.1 and Surveillance Requirements (SR) 3.2.4.2 in order to avoid confusion as to when a flux map for quadrant power tilt ratio (QPTR) monitoring is required. The following is a detailed description of the proposed changes:

  • SR 3.2.4.2, "Quadrant Power Tilt Ratio," the Note is revised to be consistent with the changes to LCO 3.3.1. The frequency is revised to be consistent with the intent of the previous Note.
  • LCO 3.3.1, "Reactor Trip System (RTS) Instrumentation," a Note is added to refer to LCO 3.2.4 for one Power Range Neutron Flux channel inoperable (Condition D). The existing Note becomes Note 1 and the new Note is Note 2.
  • LCO 3.3.1, "Reactor Trip System (RTS) Instrumentation," Required Actions D.1.2, D.2.1 and D.2.2 are deleted. The remaining Required Actions are renumbered accordingly.

Appropriate TS Bases changes would be made consistent with the TS changes.

2. Background Amendment No. 180/173 approved the incorporation of WCAP-14333. In this application, LCO 3.3. 1, Condition D was revised to allow 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to place a channel in trip as opposed to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, but the requirement to perform SR 3.2.4.2 in Required Action D.2.2 remained once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. As a result, there is a potential for confusion with the layout of the current TS 3.3.1, Condition D. TS LCO 3.3.1, Condition D could incorrectly lead an operator to believe that he could pursue the option of Required Actions D.1.1 and D.1.2, potentially overlooking the requirement to do a flux map for QPTR within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. In addition, Required Actions with shorter Completion Times (12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />) should appear before Required Actions with longer Completion Times (72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />) in the D.2.1 and 0.2.2 option.

Deleting Required Action D.1.2, D.2.1 and D.2.2 from LCO 3.3.1, Condition D eliminates requirements that are duplicative to LCO 3.2.4, thereby eliminating the potential for confusion. Finally, SR 3.2.4.2 is revised to be consistent with the proposed changes to LCO 3.3.1, Condition D.

3. Technical Evaluation Amendment No. 180/173 approved relaxation of allowed bypass test times and Completion Times for Umiting Conditions for Operation (LCO) 3.3.1, "Reactor Trip System (RTS) Instrumentation." These relaxations are those that were generically approved in WCAP-14333-P-A, Revision 1, "Probabilistic Risk Analysis of the RPS and ESFAS Test Times and Completion Times." The amendment allowed completion Times of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> for inoperable analog instruments, and bypass times of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing of analog channels.

E1-2 to NL-14-0635 Basis for Proposed Change Condition 0 applies to the Power Range Neutron Flux channel. If one channel is inoperable, then the channel must be placed in trip within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> as stated in Required Action 0.1.1. In addition to placing the inoperable channel in the tripped condition, the Required Action in 0.1.2 requires the thermal power reduced to s 75% RTP within 78 hours9.027778e-4 days <br />0.0217 hours <br />1.289683e-4 weeks <br />2.9679e-5 months <br />. An alternate to 0.1.1 and 0.1.2 is to place the inoperable channel in the tripped condition and perform SR 3.2.4.2 once every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Alternatively, LCO 3.2.4, SR 3.2.4.2 requires a flux map to be performed whenever input from one or more Power Range Neutron Flux channels is inoperable with power > 75% RTP. This flux map must currently be performed once within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> thereafter. The requirement for every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> thereafter is listed in the Surveillance Frequency Control Program. The existing layout of LCO 3.3.1, Condition 0 could incorrectly lead an operator to believe that they could pursue just the option of 0.1.1 and 0.1.2, potentially overlooking the requirement to do a flux map for QPTR within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The proposed amendment would revise TS 3.3.1 Condition 0 to avoid confusion as to when a flux map for QPTR is required.

Per this amendment request, LCO 3.3.1 Required Actions 0.1.2, 0.2.1 and 0.2.2 are deleted. The LCO 3.3.1 Condition 0 Note is modified to direct the operator to refer to LCO 3.2.4 for an inoperable power range channel. The requirement to perform SR 3.2.4.2 is defined in LCO 3.2.4. The Note to existing SR 3.2.4.2 is revised to state that SR 3.2.4.2 is only required when the Power Range Neutron Flux input to QPTR is inoperable. If the otherwise inoperable power range channel remains capable of providing a valid input to QPTR, there is no need to perform SR 3.2.4.2. This is consistent with the existing requirements of LCO 3.3.1, Condition 0 that are proposed for deletion. This proposed change will help eliminate potential confusion regarding the completion time to perform SR 3.2.4.2.

4. Regulatory Evaluation 4.1 Significant Hazards Consideration Southern Nuclear Operating Company (SNC) proposes to revise the Joseph M. Farley Nuclear Plant (FNP) Unit 1 and Unit 2 Technical Specifications (TS). The proposed amendment would modify Technical Specification (TS) Limiting Condition for Operation (LCO) 3.3.1 and Surveillance Requirements (SR) 3.2.4.2. The proposed amendment will better align the requirement to perform a flux map once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> with LCO 3.2.4. The following is a detailed description of the proposed changes.
  • LCO 3.3.1, "RTS Instrumentation," a Note is added to refer to LCO 3.2.4 for an Inoperable Power Range Channel. The existing Note becomes Note 1 and the new Note is Note 2.
  • LCO 3.3.1, "RTS Instrumentation," Required Actions 0.1.2, 0.2.1 and 0.2.2 are deleted. The remaining Required Actions are renumbered accordingly.

E1-3 to NL-14-0635 Basis for Proposed Change

  • SA 3.2.4.2, "QPTR," the Note is revised to be consistent with the changes to LCO 3.3.1.

As required by 10 CFR 50.91 {a), SNC has evaluated the proposed changes to the FNP TS using the criteria in 10 CFR 50.92 and has determined that the proposed changes do not involve a significant hazards consideration. An analysis of the issue of no significant hazards consideration is presented below:

1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No The proposed changes do not adversely affect accident initiators or precursors nor alter the design assumptions, conditions, or configuration of the facility or the manner in which the plant is operated and maintained. The proposed changes do not alter or prevent the ability of structures, systems, and components {SSCs) from performing their intended function to mitigate the consequences of an initiating event within the assumed acceptance limits. The proposed changes do not affect the source term, containment isolation, or radiological release assumptions used in evaluating the radiological consequences of an accident previously evaluated. Further, the proposed changes do not increase the types or amounts of radioactive effluent that may be released offsite, nor significantly increase individual or cumulative occupational/public radiation exposures. The proposed changes are consistent with safety analysis assumptions and resultant consequences.

Therefore, the proposed changes do not increase the probability or consequences of an accident previously evaluated.

2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No The proposed changes do not result in a change in the manner in which the ATS and ESFAS provide plant protection. The RTS and ESFAS will continue to have the same setpoints after the proposed changes are implemented. There are no design changes associated with the license amendment.

The changes do not involve a physical alteration of the plant (i.e.,

no new or different type of equipment will be installed) or a change in the methods governing normal plant operation. In addition, the changes do not impose any new or different requirements or eHminate any existing requirements. The changes do not alter E1-4 to NL-14-0635 Basis for Proposed Change assumptions made in the safety analysis. The proposed changes are consistent with the safety analysis assumptions and current plant operating practice.

Therefore, the proposed changes do not create the possibility of a new or different kind of accident from any previously evaluated.

3. Do the proposed changes involve a significant reduction in a margin of safety?

Response: No The proposed changes do not alter the manner in which safety limits, limiting safety system settings or limiting conditions for operation are determined. The safety analysis acceptance criteria are not impacted by these changes. Redundant RTS and ESFAS trains are maintained, and diversity with regard to the signals that provide reactor trip and engineered safety features actuation is also maintained. All signals credited as primary or secondary, and all operator actions credited in the accident analyses will remain the same. The proposed changes will not result in plant operation in a configuration outside the design basis.

Therefore, the proposed changes do not involve a significant reduction in the margin of safety.

Based upon the above analysis, SNC concludes that the proposed amendment does not involve a significant hazards consideration, under the standards set forth in 10 CFR 50.92(c), "Issuance of Amendment,"

and accordingly, a finding of "no significant hazards consideration" is justified.

4.2 Applicable Regulatory Requirements I Criteria The regulatory bases and guidance documents associated with the system discussed in this amendment applications included:

GDC-2 requires that structures, systems, and components important to safety be designed to withstand the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, floods, tsunami, and seiches without the loss of the capability to perform their safety functions.

GDC-13 requires that instrumentation shall be provided to monitor variables and systems over their anticipated ranges for normal operation, for anticipated operational occurrences, and for accident conditions as appropriate to assure adequate safety, including those variables and systems that can affect the fission process, the integrity of the reactor core, the reactor coolant pressure boundary, and the containment and its associated systems.

E1-5 to NL-14-0635 Basis for Proposed Change GDC-20 requires that the protection system(s) shall be designed (1) to initiate automatically the operation of appropriate systems including the reactivity control systems, to assure that specified acceptable fuel design limits are not exceeded as a result of anticipated operational occurrences and (2) to sense accident conditions and to initiate the operation of systems and components important to safety.

GDC-21 requires that the protection system(s) shall be designed for high functional reliability and testability.

GDC-22 through GDC-25 and GDC-29 require various design attributes for the protection system(s), including independence, safe failure modes, separation from control systems, requirements for reactivity control malfunctions, and protection against anticipated operational occurrences.

Regulatory Guide 1.22 discusses an acceptable method of satisfying GDC-20 and GDC-21 regarding the periodic testing of protection system actuation functions. These periodic tests should duplicate, as closely as practicable, the performance that is required of the actuation devices in the event of an accident.

10 CFR 50.55a(h) requires that the protection systems meet IEEE 279-1971. Section 4.2 of IEEE 279-1971 discusses the general functional requirement for protection systems to assure they satisfy the single failure criterion.

There will be no changes to the RTS instrumentation design such that compliance with any of the regulatory requirements and guidance documents above would come into question. The above evaluations confirm that the plant will continue to comply with all applicable regulatory requirements.

4.3 Precedent The NRC approved a similar TS change for the Vogtle Electric Generating Plant by letter dated August 15, 2006 (Package No. ML061880216).

4.4 Conclusions In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

5. Environmental Considerations SNC has evaluated the proposed change and determine that the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or a significant increase in the amounts of any E1-6 to NL-14-0635 Basis for Proposed Change effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

QPTR B 3.2.4 BASES ACTIONS A.6 (continued) surveillances performed at operating power levels, which can only be accomplished after the excore detectors are normalized to restore QPTR to within limits and the core returned to power.

If Required Actions A.1 through A.6 are not completed within their associated Completion Times, the unit must be brought to a MODE or condition in which the requirements do not apply. To achieve this status, THERMAL POWER must be reduced to < 50% RTP within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

SURVEILLANCE SR 3.2.4.1 REQUIREMENTS SR 3.2.4.1 is modified by two Notes. Note 1 allows QPTR to be calculated with three power range channels if THERMAL POWER is s 75% RTP and the input from one Power Range Neutron Flux channel is inoperable. Note 2 allows performance of SR 3.2.4.2 in lieu of SR 3.2.4.1.

This Surveillance verifies that the QPTR, as indicated by the Nuclear Instrumentation System (NIS) excore channels, is within its limits.

The Surveillance Frequency is controlled under the Surveillance Frequency Control Program. For those causes of QPT that occur quickly (e.g., a dropped rod), there typically are other indications of

Insert A The Required Actions have been modified by two Notes. Note 1 allows a channel to be placed in the bypassed condition for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> while performing routine surveillance testing. With one channel inoperable, the Note also allows routine surveillance testing of another channel with a channel in bypass. The Note also allows placing a channel in the bypass condition to allow setpoint adjustments when required to reduce the Power Range Neutron Flux-High setpoint in accordance with other Technical Specifications. The 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> time limit is justified in Reference 11.

Note 2 refers the user to LCO 3.2.4 for additional requirements that may apply for an inoperable power range channel.
