UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 301 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-53 AND AMENDMENT NO. 278 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-69 CALVERT CLIFFS NUCLEAR POWER PLANT, LLC CALVERT CLIFFS NUCLEAR POWER PLANT. UNIT NOS. 1 AND 2 DOCKET NOS. 50-317 AND 50-318

1.0 INTRODUCTION

By application dated August 31, 2011 (Agencywide Documents Accession and Management System (ADAMS) Accession No. ML11244A132), Calvert Cliffs Nuclear Power Plant, LLC, the licensee, requested changes to the Technical Specifications (TSs) for Calvert Cliffs Nuclear Power Plant, Unit Nos. 1 and 2. The proposed changes would revise TS 3.4.1, "RCS [reactor coolant system] Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB)

Limits," the bases for TS 3.4.1 and TS 5.6.5, "Core Operating Limits Report [COLR)." by replacing the DNB numeric limits with references to the COLR. The changes are consistent with TS Task Force change traveler TSTF-487-A, Revision 1, "Relocate DNB Parameters to the COLR." The proposed changes also include removal of outdated notes in TS 3.4.1.c and Surveillance Requirement (SR) 3.4.1.3 that were temporarily inserted to support replacement of the steam generators in 2002.

These changes would allow the licensee to recalculate the DNB parameter limits using Nuclear Regulatory Commission (NRC)-approved methodologies without the need for a license amendment request (LAR).

The proposed changes include the following:

  • Change TS 3.4.1, "RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB) Limits," and the associated Surveillance Requirements (SRs) to replace the specific limit values of RCS pressurizer pressure, cold leg temperature, and RCS total flow rate with "the limits specified in the COLR."
  • Change the bases for limiting condition for operation (LCO) 3.4.1 to reflect that the DNB limits are specified in the COLR.
  • Change T8 5.6.5, "Core Operating Limits Report," to add the methodology requirements used to calculate the DNB limits.

-2

Generic Letter (GL) 88-16, "Removal of Cycle-Specific Parameter Limits from Technical Specifications," is the regulatory guidance for this change.

2.0 REGULATORY EVALUATION

The Commission's regulatory requirements related to the content of TSs are specified in Title 10 of the Code of Federal Regulations (10 CFR), Section SO.36, "Technical specifications."

10 CFR SO.36(c)(2)(I) defines that LCOs are the lowest functional capability or performance levels of equipment required for safe operation of the facility. For the DNB parameters, 10 CFR SO.36(c)(2)(ii)(B) Criterion 2 applies, which requires that TS LCOs be established for each process variable, design feature, or operating restriction that is an initial condition of a design basis accident or transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier.

LARs are required for each fuel cycle design that results in changes to parameter limits specified in TS. To meet 10 CFR SO.36(c)(2)(ii) requirements and alleviate the need for LARs to update parameter limits every fuel cycle, the NRC issued GL 88-16 with specific guidance for replacing the limit values for cycle-specific parameters in the TSs with references to an owner controlled document, namely, the COLR. The guidance in GL 88-16 includes the following three actions:

1. The addition of the definition of a named formal report (Le., COLR) in TSs that 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 analyses.
2. The addition of an administrative reporting requirement (in TS S.6.S) to submit the formal report on cycle-specific parameter limits to the Commission for information.
3. The modification of individual TSs to note that the specific parameters shall be maintained within the limits provided in the defined formal report (COLR).

The proposed change has been evaluated against GL 88-16 and found to be conSistent with that regulatory guidance.

3.0 TECHNICAL EVALUATION

3.1 TSTF-487 -A, Revision 1 TS LCO 3.4.1 specifies the limit values of the DNB parameters to assure that the pressurizer pressure, the RCS cold leg temperature, and RCS flow rate during operation at rated thermal power (RTP) will be maintained within the limits assumed in the safety analyses in the final safety analysis report (FSAR). The safety analyses of anticipated operational occurrences (AOOs) and accidents assume initial conditions within the envelope of normal steady state operation at the RTP to demonstrate that the applicable acceptance criteria, including the specified acceptable fuel design limits (such as DNB ratio) and RCS pressure boundary design conditions, are met for each event analyzed. The TS limits placed on the DNB-related

-3 parameters ensure that these parameters, when appropriate measurement uncertainties are applied, will be bounded by those assumed in the safety analyses, and thereby provide assurance that the applicable acceptance criteria will not be violated should a transient or accident occur while operating at the RTP.

It is essential to safety that the plant is operated within the ONB parameter limits. This change retains the requirement to maintain the plant within the ONB parameter limits in LCO 3.4.1 along with the SR verification for each of the ONB parameters. As these parameter limits are calculated using NRC-approved methodologies and are consistent with all applicable limits of the plant safety analyses, this change does not affect nuclear safety.

TS 5.6.5, "Core Operating Limits Report," specifies that the core operating limits shall be determined such that all applicable limits of the safety analyses are met, and that the analytical methods used to determine the core operating limits shall be those previously reviewed and approved by the NRC. These changes modify the list of NRC-approved methodologies in TS 5.6.5 to include those used to calculate the ONB limits on pressurizer pressure, RCS cold leg temperature, and RCS total flow rate. The limit values of these parameters in the COLR will comply with existing operating fuel cycle analysis requirements, and are initial conditions assumed in safety analyses. Replacing of the ONB parameter values with references to the COLR does not lessen the requirement for compliance with all applicable limits.

Any revisions to the safety analyses that require prior NRC approval will be identified by the 10 CFR 50.59 review process. TS 5.6.5 also specifies that the COLR, including any midcycle revisions or supplements, shall be provided upon issuance for each reload cycle to the NRC.

This will allow NRC staff to continue trending the information even though prior NRC approval of the changes to these limits will not be required.

10 CFR 50.36 requires LCOs to contain the lowest functional capability or performance levels of equipment for safe operation of the facility. The NRC staff finds that the proposed change to LCO 3.4.1 referencing the specific values of the ONB parameter limits in TS in the COLR continues to meet the regulatory requirement of 10 CFR 50.36(c)(2)(ii)(B) (Criterion 2), and follows the guidance described in GL 88-16. The NRC staff, therefore, concludes that this change is acceptable.

For safety analyses of transients or accidents, various sections of Chapter 15 of the Standard Review Plan specify that the reactor is initially at the RTP plus uncertainty, and the RCS flow is at nominal design flow including the measurement uncertainty. If one or more ONB parameter limits change, and these changes do not support the RTP, a license amendment would be required to either reduce the RTP or limit the plant operation at a level below the RTP. 10 CFR Part 50 Appendix K requires that the loss-of-coolant accident analysis be performed at 102% of the RTP. Other plant-specific analyses can contain an initial condition to be performed at RTP.

To ensure a clear understanding of this requirement, TS 5.6.5.c. has been reworded to add the underlined text:

The core operating limits shall be determined assuming operation at RTP such that all applicable limits (e.g., fuel thermal mechanical limits, core thermal hydraulic limits, ECCS [emergency core cooling system] limits, nuclear limits such as SOM [shutdown margin], transient analysis limits, and accident analysis limits) of the safety analysis are met.

-4 The NRC staff has reviewed this proposed change to replace the values of the DNB parameters in TS with references to the COLR. This change will allow the licensee the flexibility to manage operating and core design margins associated with the DNB parameters without the need for cycle-specific LARs. Any future revisions to safety analyses that require prior NRC approval will be identified by the 10 CFR 50.59 review process. Based on this evaluation, the NRC staff concludes that this change meets the regulatory requirements of 10 CFR 50.36, follows the guidance described in GL 88-16, and is acceptable.

3.2 Removal of Notes to TS 3.4.1 Amendments Nos. 249 and 225 for Calvert Cliffs Nuclear Power Plant, Unit Nos. 1 and 2, respectively, issued on March 1, 2002 (ADAMS Accession No. ML012400449), included temporary notes in TS 3.4.1 that reflected replacement of the steam generators. As discussed in the safety evaluation, TS 3.4.1.c requires a minimum RCS flow rate of 370,000 gpm and SR 3.4.1.3 requires verification every 12 hours0.5 days <br />0.0714 weeks <br />0.0164 months <br />. However, due to steam generator tube plugging over the years, this flow rate could no longer be attained with the original steam generators. As a result, RCS flow was limited to 340,000 gpm.

When the Unit No. 1 steam generators were replaced in the spring 2002 refueling outage, the original RCS flow rate was restored. Unit No.2 steam generator replacement was scheduled for the spring 2003 refueling outage. Therefore, a temporary note was inserted into TS 3.4.1.c and SR 3.4.1.3 stating that the Unit No.2 RCS flow rate remained at 340,000 gpm. When the Unit No.2 steam generator replacement was completed in 2003, the notes were no longer applicable.

The licensee has proposed removing these notes as they are no longer applicable. The NRC staff considers this change to be administrative and approves removing the notes.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Maryland State official was notified of the proposed issuance of the amendments. 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 and changes Surveillance Requirements. 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 (76 FR 64390). 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.
