UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 328 TO FACILITY OPERATING LICENSE NO. DPR-77 AND AMENDMENT NO. 321 TO FACILITY OPERATING LICENSE NO. DPR-79 TENNESSEE VALLEY AUTHORITY SEOUOYAH NUCLEAR PLANT, UNITS 1 AND 2 DOCKET NOS. 50-327 AND 50-328
1.0 INTRODUCTION
By letter dated January 26, 2010 (Agencywide Documents Access and Management System Accession No. ML100290024), Tennessee Valley Authority (TVA or the licensee) submitted a license amendment request for the Sequoyah Nuclear Plant (SON), Units 1 and 2, to revise the Technical Specification (TS) Table 3.3-1 to resolve an oversight regarding the operability requirements for the intermediate range neutron flux channels. TVA proposes to add an action to TS Table 3.3-1 to define that the provisions of Specification 3.0.3 are not applicable above 10 percent of thermal rated power with the number of operable intermediate range neutron flux channels two less than the minimum channels operable requirement. This proposed change applies to SON, Units 1 and 2, TS Table 3.3-1 "Reactor Trip System Instrumentation," Functional Unit 5, "Intermediate Range, Neutron Flux."
In the current version of the TS Table 3.3-1, it does not provide an action that addresses the declaration of two intermediate range neutron flux channels inoperable in Mode 1 with power above 10 percent of thermal rated power, (i.e., the P-1 0 setpoint). As a result, TS 3.0.3 would apply. TVA believes that this requirement is unnecessarily restrictive, because the intermediate range neutron flux channels do not provide a protection function above the P-10 setpoint. Above the P-1 0 setpoint, the power range neutron flux trip and the power range neutron flux high positive rate trip provide core protection for a rod withdrawal accident.
In order to resolve this issue, TVA proposed in the license amendment that the following action be added to TS Table 3.3-1 for SON, Units 1 and 2:
ACTION 17 - With the number of OPERABLE channels two less than the minimum channels OPERABLE requirement and with the THERMAL POWER level above 10% of RATED THERMAL POWER, the provisions of Specification 3.0.3 are not applicable.

2.0 REGULATORY EVALUATION
Section 182a of the Atomic Energy Act (the "Act") requires applicants for nuclear power plant operating licenses to include TSs as part of the license. The Commission's regulatory requirements related to the content of TSs are set forth in Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Section 50.36. In particular, 10 CFR 50.36(c)(3), "Surveillance requirements," states:
Surveillance requirements are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met.
In the "Regulatory Evaluation" section of the licensee's January 26, 2010, submittal, the licensee stated that "This proposed change does not change regulatory requirements. The proposed change is consistent with the intent of NUREG-1431, Revision 3, "Standard Technical Specifications [STS] Westinghouse Plants," which establishes that the mode of applicability for the intermediate range neutron flux function in Mode 1 is when the thermal power is below the P1 0 (Power Range Neutron Flux) interlocks as depicted in Table 3.3.1-1, Function 4, Applicable Modes."
3.0 TECHNICAL EVALUATION
In the "Technical Evaluation" section of the submittal, the licensee stated that the intermediate range neutron flux trip function provides protection against an uncontrolled rod cluster control assembly bank withdrawal accident from a subcritical condition during startup. This trip function provides redundant protection to the power range, neutron flux low setpoint trip function.
Section 7.2.1.1.2.1.b of the SON Updated Final Safety Analysis Report (UFSAR) states, "The intermediate range high neutron flux trip circuit trips the reactor when one out of the two intermediate range channels exceed the trip setpoint. This trip, which provides protection during reactor startup, can be manually blocked if two out of four power range channels are above approximately 10 percent power (P-1 0). Three out of the four power range channels below this value automatically reinstates the intermediate range high neutron flux trip. The intermediate range channels (including detectors) are separate from the power range channels. The intermediate range channels can be individually bypassed at the nuclear instrumentation racks to permit channel testing at any time under prescribed administrative procedures and only under the direction of authorized supervision. This bypass action is annunciated on the control board."
The licensee further stated that the intermediate range neutron flux trip must be operable in Mode 1 below the P-10 setpoint and in Mode 2 when there is a potential for an uncontrolled rod withdrawal accident during reactor startup. Above the P-1 0 setpoint, the power range neutron flux high setpoint trip and the power range neutron flux high positive rate trip provide core protection for a rod withdrawal accident. Since the power range detectors perform the monitoring and protection functions above the P-10 setpoint, the intermediate range is not required above the P-10 setpoint. Therefore, the provisions of TS 3.0.3 should not be for two inoperable intermediate range neutron flux channels above the P-1 0 setpoint.
-3 The Nuclear Regulatory Commission (NRC) staff reviewed the licensee's submittal and related documentation (e.g., TS, UFSAR, STS). The NRC staff noted the statement in Section 7.2.1.121.b of the SON UFSAR, Revision 20, 'The intermediate range high neutron flux trip circuit trips the reactor when one out of the two intermediate range channels exceed the trip setpoint. This trip, which provides protection during reactor startup, can be manually blocked if two out of four power range channels are above approximately 10 percent power (P-1 0)." The NRC staff also reviewed the proposed change versus the Table 3.3.1-1, "Reactor Trip System Instrumentation," Function 4, of the STS for the Westinghouse plants, and concluded that the proposed change is consistent with the intent of the NRC approved STS, which requires that the mode of applicability for the intermediate range neutron flux function in Mode 1 is when the thermal power is below the P-1 0 (Power Range Neutron Flux) interlocks. The NRC staff, therefore, concluded that with the number of operable channels, two less than the minimum channels operable requirement, and with the thermal power level above 10% of rated thermal power, the provisions of TS 3.0.3 are not applicable for the intermediate range neutron flux channels. The proposed change is in accordance with the UFSAR reactor trips and accident analysis, as discussed in Chapter 15 of the UFSAR.
The proposed license amendment request was evaluated by the NRC staff to determine whether applicable regulations and requirements continue to be met. The proposed change meets the intent of NUREG-1431, Revision 3. The intermediate range neutron flux function is applicable in Mode 1 for thermal power below 10 percent. For thermal power above 10 percent, the power range neutron flux trips provide core protection for rod withdrawal accident. Since the intermediate range neutron flux channels do not provide a protective function above the P-10 setpoint, the NRC staff finds this license amendment request acceptable. Further, applicable regulatory requirements will continue to be met, adequate defense-in-depth will be maintained, and sufficient safety margins will be maintained.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Tennessee State official was notified of the proposed issuance of the amendment. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendments change a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public comment on such finding (75 FR 13791, March 23, 2010). Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.

6.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that: (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) the issuance of these amendments will not be inimical to the common defense and security or to the health and safety of the public.
