SUBJECT:

DUANE ARNOLD ENERGY CENTER - ISSUANCE OF AMENDMENT TO REVISE TECHNICAL SPECIFICATIONS TO ADOPT TSTF-522 (TAC NO. MF0460)

Dear Mr. Anderson:

The U.S. Nuclear Regulatory Commission has issued the enclosed Amendment No. 285 to Renewed Facility Operating License No. DPR-49 for the Duane Arnold Energy Center. The amendment consists of changes to the technical specifications (TSs) in response to your application dated December 21, 2012. The amendment adopts NRC-approved Technical Specification Task Force (TSTF) - 522, "Revise Ventilation System Surveillance Requirements to Operate For 10 Hours Per Month."

The amendment revises the surveillance requirement (SR) which currently requires operating the standby gas treatment (SGT) system, with the electrical heaters operating, for a continuous 10 hour1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> period at a frequency specified in the Surveillance Frequency Control Program. This SR 3.6.4.3.1 is revised to require operation of the system for 15 continuous minutes without the heaters operating.

In addition, the requirements for testing the SGT system specified in the ventilation filter testing program in TS 5.5.7, are revised accordingly to remove the electric heater output test (TS 5.5.7.e) and to increase the specified relative humidity (RH) for the charcoal testing from the current 70 percent to 95 percent RH in TS 5.5.7.c.

A copy of the Safety Evaluation is also enclosed. A Notice of Issuance will be included in the Commission's next biweekly Federal Register notice.

DAEC 5.0-14 Amendment 285

UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555*0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 285 TO FACILITY OPERATING LICENSE NO. DPR-49 NEXTERA ENERGY DUANE ARNOLD, LLC DUANE ARNOLD ENERGY CENTER DOCKET NO. 50-331

1.0 INTRODUCTION

By application dated December 21, 2012 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML12356A184). NextEra Energy Duane Arnold, LLC, (the licensee), requested changes to the technical specifications (TSs) for Duane Arnold Energy Center. Specifically, the licensee requested changes to the Ventilation Filter Testing Program (VFTP) as well as to adopt U.S. Nuclear Regulatory Commission (NRC or Commission) approved Technical Specifications Task Force (TSTF) Standard Technical Specifications (STS)

Change Traveler TSTF-522, "Revise Ventilation System Surveillance Requirements to Operate for 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> per Month" ADAMS Accession No. ML100890316), dated March 30, 2010.

The proposed changes would revise and delete certain testing requirements in TS 5.5.7, "Ventilation Filter Testing Program" as well as change Surveillance Requirement (SR) 3.6.4.3.1.

TS 5.5.7.c would be changed to increase the required minimum relative humidity (RH) for testing charcoal adsorber in the standby gas treatment (SBGT) system from 70 percent to 95 percent. The TS 5.5.7.e testing requirement to demonstrate that the SBGT system heaters dissipate at least 22 kW would be deleted. SR 3.6.4.3.1 in TS 3.6.4.3.1, "Standby Gas Treatment (SBGT) System," currently requires operating the SBGT system for at least 10 continuous hours with the heaters operating at a frequency controlled in accordance with the surveillance frequency control program (SFCP). The SR would be changed to require at least 15 continuous minutes of ventilation system operation at a frequency controlled in accordance with the SFCP and the requirement to operate the heaters during the SR would be removed.

The licensee stated that the license amendment request IS consistent with NRC-approved Traveler TSTF-522. The availability of this TS improvement was announced in the Federal Register on September 20,2012 (77 FR 58421), as part of the consolidated line item improvement process. While the licensee's proposed changes to required ventilation system operation time in SR 3.6.4.3.1 are consi~tent with TSTF-522, the proposed changes to delete the SR 3.6.4.3.1 requirement to operate system heaters and the proposed changes to TS 5.5.7 requirements are beyond the scope of the review performed for TSTF-522. The scope of the TSTF-522 review assumed licensees would maintain all VFTP requirements and heater operation requirements if the heater operation requirements existed in their TS.

2.0 REGULATORY EVALUATION

One of the reasons air filtration and adsorption systems are required at nuclear power plants is to lower the concentration of airborne radioactive material that may be released from the site to the environment due to a design basis event. Lowering the concentration of airborne radioactive materials can mitigate doses to plant operators and members of the public in the event of a design basis event. A typical system consists of ventilation ductwork, fans, dampers, valves, instrumentation, prefilters or demisters, high-efficiency particulate air (HEPA) filters, heaters, and activated charcoal adsorbers. These systems are tested by operating the systems and monitoring the response of the overall system as well as individual components.

Laboratory tests of charcoal adsorbers are also performed to ensure the charcoal adsorbs an acceptable amount of radioactive gases.

Current testing requirements for the air filtration and adsorption systems state that the systems should be operated for at least 10 continuous hours with heaters operating every 31 days or at a frequency controlled by the SFCP for plants with a SFCP. These requirements are based on NRC staff guidance for testing air filtration and adsorption systems that has been superseded.

New NRC staff guidance states at least 15 continuous minutes of ventilation system operation with heaters operating is acceptable for those plants that test ventilation system adsorption at a RH of less than 95 percent. Plants that test ventilation system adsorption at a RH of 95 percent do not require heaters for the ventilation system to perform its specified safety function and the bracketed phrase "with heaters operating" is not included in the SRs.

The licensee has proposed revising SRs, which currently require operating the ventilation system for at least 10 continuous hours with the heaters operating at a frequency controlled in accordance with the SFCP. The SRs would be changed to require at least 15 continuous minutes of ventilation system operation at a frequency controlled in accordance with the SFCP.

The SR would no longer require heaters to be operated during the test.

The regulatory requirements for design and testing of these systems are contained in Title 10 of the Code of Federal Regulations (10 CFR) Section 50.67 and Part 100, as well as Part 50, Appendix A, "General Design Criteria for Nuclear Power Plants," General Design Criteria 19, 41, 42,43, and 61.

Regulatory Guide (RG) 1.52, Revision 2, "Design, Testing, and Maintenance Criteria for Post-Accident Engineered-Safety-Feature Atmosphere Cleanup System Air Filtration and Adsorbtion Units of Light-Water-Cooled Nuclear Power Plants" (ADAMS Accession No. ML003740139) was published in March 1978 to provide guidance and criteria acceptable to the NRC staff for licensees to implement the regulations in 10 CFR related to air filtration and adsorption systems.

Regulatory Position 4.d of Revision 2 of RG 1.52 stated that "Each ESF [engineered safety feature] atmosphere cleanup train should be operated at least 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> per month, with the heaters on (if so equipped), in order to reduce the buildup of moisture on the adsorbers and HEPA filters." The purpose of this position is to minimize the moisture content in the system and thereby enhance efficiency in the event the system is called upon to perform its design basis function. STS SRs 3.6.4.3.1 and 3.7.4.1 currently require operating the heaters in the respective ventilation and filtering systems for at least 10 continuous hours. The current STS

-3 Bases explain that operation of heaters for 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> would eliminate moisture on the charcoal adsorbers and HEPA filters.

The NRC staff issued NRC Generic Letter (GL) 99-02: "Laboratory Testing of Nuclear-Grade Activated Charcoal" (ADAMS Accession No. ML082350935 and errata sheet at Accession No. ML031110094). GL 99-02 requested licensees to confirm their charcoal testing protocols accurately reflect the adsorber gaseous activity capture capability. GL 99-02 also requested the licensees to account for the effects of moisture accumulation in adsorbers. The NRC staff then issued a draft revision of RG 1.52, DG-11 02, to solicit comments on changes to the RG. The NRC staff received comments from the Nuclear HVAC Utilities Group (NHUG), among others.

NHUG stated that 10 continous hours of system operation would dry out the charcoal adsorber for a brief period of time but, following heater de-energization, the level of moisture accumulation in adsorbers would rapidly return to the pre-test level.

Therefore, the NRC staff updated RG 1.52 to include the new information (ADAMS Accession No. ML011710176). RG 1.52, Revision 3, Regulatory Position 6.1 states, "Each ESF atmosphere cleanup train should be operated continuously for at least 15 minutes each month, with the heaters on (if so equipped), to justify the operability of the system and all its components."

One of the reasons for the previous 10-hour requirement for ventilation system operation with heaters operating was to minimize the effects of moisture on the ad sorber's ability to capture gaseous activity. However, these effects are accounted for in a ventilation filter testing program (VFTP) by performing testing at a RH of 95 percent. The Duane Arnold TS 5.5.7 VFTP currently requires testing charcoal adsorbers at a RH of 70 percent. The licensee has proposed changing the required RH for the charcoal adsorber test to 95 percent to account for the effects of moisture on the adsorber's ability to capture gaseous activity. Therefore, the licensee proposed to remove the requirement to operate heaters from SRs 3.6.4.3.1 and TS 5.5.7.e.

The NRC's regulatory requirements related to the content of the TS are contained in 10 CFR 50.36. The regulations at 10 CFR 50.36 require that the TS include items in the following categories: (1) safety limits, limiting safety systems settings, and limiting control settings; (2) limiting conditions for operation (LCOs); (3) SRs; (4) design features; and (5) administrative controls. 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 LCOs will be met.

The NRC's guidance for the format and content of licensee TSs can be found in NUREG-1433, "Standard Technical Specifications General Electric Plants BWRl4."

3.0 TECHNICAL EVALUATION

The NRC staff evaluated the licensee's proposed change against the applicable regulatory guidance in RG 1.52, Revision 3, guidance in the STS as modified by TSTF-522, and the regulatory requirements of 10 CFR 50.36.

- 4 The proposed change would require at least 15 minutes of system operation. The NRC staff found that the proposed change is consistent with guidance in RG 1.52, Revision 3.

The NRC staff evaluated the licensee's proposed change against the applicable regulatory guidance in the STS, as modified by TSTF-522. The proposed change adopted the TS format and content, to the extent practicable, contained in the changes made to NUREG-1433, "Standard Technical Specifications General Electric Plants BWRl4" by TSTF-522. The NRC staff found that the proposed change is consistent with guidance in the STS, as modified by TSTF-522.

The NRC staff evaluated the licensee's proposed changes to the VFTP and the proposed removal of requirements to operate the system heaters. The requirements for testing the SGT system specified in the VFTP in TS 5.5.7, are revised accordingly to remove the electric heater output test (TS 5.5.7.e), and to increase the specified RH for the charcoal testing from the current 70% to 95 percent RH in TS 5.5. Tc.

The original 1O-hour duration SGT system monthly run surveillance was intended to demonstrate operability of the filter and the charcoal adsorber bed and remove excessive moisture built up on the adsorber. With the implementation of TSTF-522 and the licensee's adaption of the more stringent charcoal testing requirements from ASTM D3803-1989, specifically, charcoal sample testing to the temperature of 30 °C (86 OF) and a RH of 95 percent, the requirement for an electric heater output test is no longer applicable.

The staff agrees that testing the SGT for 15 minutes without heaters and performing the charcoal testing at 95 percent RH is sufficient to verify that the safety function of the SGT is met and, that this change does not reduce the safety of the system. While these changes were outside the scope of changes considered in review of TSTF-522, the staff found that the proposed changes are acceptable.

The NRC staff compared the proposed change to the existing SRs, as well as the regulatory requirements of 10 CFR 50.36. The existing SRs provide assurance that the necessary quality of ventilation systems and components will be maintained and that the LCOs will be met. The proposed change reduces the amount of required system operational time from 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> to 15 minutes. The 10-hour operational requirement for heaters was based on using the SR to eliminate moisture in the adsorbers and thus ensure the adsorbers would capture gaseous activity. As discussed in Section 2.0, the effects of moisture on the adsorber's ability to capture gaseous activity are now accounted for in the licensee's VFTP by performing testing at a RH of 95 percent. Since the SR's are no longer relied upon to ensure the effects of moisture on the adsorber's ability to capture gaseous activity are accounted for, the 10-hour heater operational requirement is unnecessary. The NRC staff found that reducing the required minimum system operation time to 15 minutes, consistent with RG 1.52, Revision 3, in conjunction with the VFTP, is sufficient to justify operability of the system and all its components. The NRC staff found that the proposed SRs meet the regulatory requirements of 10 CFR 50.36 because they provide assurance that the necessary quality of ventilation systems and components will be maintained and that the LCOs will be met. Therefore, the NRC staff finds the proposed change acceptable.

- 5 The regulation at 10 CFR 50.36 states: "A summary statement of the bases or reasons for such specifications ... shall also be included in the application, but shall not become part of the technical specifications."

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Iowa State official was notified on July 1s t.

2013 of the proposed issuance of the amendment. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

S This amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 or changes a surveillance requirement. The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluent 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 amendment involves no significant hazards consideration and there has been no public comment on such finding (78 FR 22571) on April 16, 2013. Accordingly, the amendment meets 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 amendment.

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) there is reasonable assurance that such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
