COMANCHE PEAK - UNITS 1 AND 2 3.3-14 Amendment No. 4-eQ, 151

UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555*0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 151 TO FACILITY OPERATING LICENSE NO. NPF-87 AND AMENDMENT NO. 151 TO FACILITY OPERATING LICENSE NO. NPF-89 LUMINANT GENERATION COMPANY LLC COMANCHE PEAK NUCLEAR POWER PLANT, UNITS 1 AND 2 DOCKET NOS. 50-445 AND 50-446

1.0 INTRODUCTION

By application dated April 2, 2009 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML091030383), Luminant Generation Company LLC (the licensee) requested changes to the Technical Specifications (TSs) for Comanche Peak Nuclear Power Plant (CPNPP), Units 1 and 2. The proposed amendment would revise TS 3.3.1, "Reactor Trip System (RTS) Instrumentation," to add Surveillance Requirement (SR) 3.3.1.16 to Function 3, "Power Range Neutron Flux Rate High Positive Rate," of TS Table 3.3.1-1 to verify that the reactor trip system (RTS) response times are within limits every 18 months on a staggered test basis.

2.0 REGULATORY EVALUATION

The U.S. Nuclear Regulatory Commission (NRC) staff considered the following regulatory requirements in its review of the license amendment request (LAR):

Title 10 of the Code of Federal Regulations (10 CFR) Part 50, "Domestic Licensing of Production and Utilization Facilities," establishes the fundamental regulatory requirements with respect to the domestic licensing of nuclear production and utilization facilities. Specifically, Appendix A, "General Design Criteria [GOG] for Nuclear Power Plants," to 10 CFR Part 50 provides, in part, the necessary design, fabrication, construction, testing, and performance requirements for structures, systems, and components important to safety. In its application, the licensee identified the following GDCs as being applicable to the proposed change:

• General Design Criterion 13, "Instrumentation and control," requires that instrumentation shall be provided to monitor variables and systems over their anticipated ranges for Enclosure 3

-2 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. Appropriate controls shall be provided to maintain these variables and systems within prescribed operating ranges.

• General Design Criterion 20, "Protective system functions," requires the protection system to 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.

Section 50.36, "Technical specifications," of 10 CFR requires that the TSs include items in the following specific categories: (1) Safety limits, limiting safety systems settings, and limiting control settings; (2) Limiting conditions for operations; (3) Surveillance requirements; (4) Design features; and (5) Administrative controls. The regulations in 10 CFR 50.36(c)(3), "Surveillance requirements," specify that SRs 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.

3.0 TECHNICAL EVALUATION

The positive flux rate trip (PFRT) ensures that protection is provided against rapid increases in neutron flux that are characteristic of a rod cluster control assembly (RCCA) drive rod housing rupture and the accompanying ejection of the RCCA. The PFRT was not credited previously in the CPNPP safety analysis for protection against anticipated transients or postulated accidents.

However, based on a Westinghouse reanalysis of the uncontrolled RCCA bank withdrawal at power (RWAP) transient using more conservative analytical assumptions, the licensee has determined that the PFRT should be credited in the CPNPP safety analysis for primary protection. Therefore, the licensee has proposed that TS 3.3.1, "Reactor Trip System (RTS)

Instrumentation," be revised to require that PFRT response times be verified.

In the LAR, the licensee explained that, Westinghouse Electric Corporation issued Nuclear Safety Advisory Letter (NSAL) 02-11, "Reactor Protection System Response Time Requirements," dated July 29, 2002, which notified licensees that some positive neutron flux rate trip (Le., PFRT) functions may be credited for protection against anticipated transients or postulated accidents, but may not be explicitly credited for primary protection in the specific safety analysis cases presented in the updated Final Safety Analysis Report. In an evaluation of NSAL 02-11, the licensee determined that the PFRT was not explicitly credited for primary protection, and that in those analyses where it was considered, the assumed response time was much longer than the value expected so that an explicit response time measurement was not considered necessary. The licensee reanalyzed the RWAP event using more conservative analytical assumptions and has determined that the PFRT should be credited in the CPNPP safety analysis for primary protection of the reactor core.

-3 Based on the reanalysis, the licensee is proposing that TS 3.3.1 be revised to add SR 3.3.1.16 to Table 3.3.1-1, Function 3, "Power Range Neutron Flux Rate High Positive Rate." The eXisting SR 3.3.1.16 requires verification that the RTS channel actuation response times are less than or equal to the maximum values assumed in the accident analysis. The RTS response time is defined in the TS as that time interval from when the monitored parameter exceeds its RTS trip setpoint at the channel sensor until loss of stationary gripper coil voltage.

The loss of stationary gripper coil voltage is when the operable RCCAs drop into the reactor core and shut down or trip the reactor. The existing Allowable Value for the PFRT function is s 6.3 percent rated thermal power (RTP) with time constant ~ 2 seconds.

The licensee stated that a rate setpoint of 9 percent RTP (per second) with lagging time constant of 2.0 seconds and a 6.5 second trip delay was assumed in the RWAP analysis.

These values support the nominal trip setpoint of 5 percent RTP with a time constant of

~ 2 seconds and the existing Allowable Value of S 6.3 percent RTP with a time constant of

~ 2 seconds.

The licensee has stated that in addition to the proposed TS changes, a response time limit of 0.65 seconds for the PFRT response time will be included in Table 13.3.1-1, "Reactor Trip System (RTS) Instrumentation Response Time Limits," in the Technical Requirements Manual (TRM).

The PFRT instrumentation is segmented into two interconnected portions which are (1) detectors, field contacts, and signal conditioners that are configured into four channels, and (2) logic and reactor trip breakers that are configured into two trains.

SR 3.3.1.16 verifies that the individual channel and train actuation response times are less than or equal to the maximum values assumed in the accident analysis. The required trip initiation signals and acceptance criteria for response time testing are included in the TRM. SR 3.3.1.16 has a surveillance test interval of 18 months on a staggered test basis. The surveillance performed every 18 months includes at least one channel and train such that both trains are verified at least once per 36 months and is consistent with the existing SR 3.3.1.16 requirements for other functions in TS 3.3.1. The response times of the train portions cannot be verified during normal plant operation and are normally performed during refueling outages, when the equipment can be taken out of service for performing the surveillance.

The NRC staff has reviewed the licensee's request to add SR 3.3.1.16 to Function 3 of TS Table 3.3.1-1 and concludes that the change is consistent with the existing SR 3.3.1.16 requirements for other functions in TS 3.3.1. The addition of SR 3.3.1.16 to Function 3 of TS Table 3.3.1-1 is needed since the licensee intends to take credit for the PRFT function in its analysis of the RWAP event. The NRC staff concludes that the addition of SR 3.3.1.16 to Function 3, "Power Range Neutron Flux Rate High Positive Rate," of TS Table 3.3.1-1 is the appropriate requirement to demonstrate that the response times are less than or equal to the maximum values assumed in the accident analysis and satisfies the requirements of 10 CFR 50.36 and GOCs 13 and 20.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Texas 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 published in the Federal Register on May 19, 2009 (74 FR 23446). 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 the amendments will not be inimical to the common defense and security or to the health and safety of the public.
