The supplemental letters dated June 13, 2014, and August 15, 2014, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the staff's original proposed no significant hazards consideration determination as published in the Federal Register on February 19, 2014 (79 FR 9496).
2.0 REGULATORY EVALUATION
The regulation at 10 CFR Section 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. Enclosure 3 The licensee states "The construction permits for CNP were issued and the majority of construction was completed prior to issuance of 10 CFR 50, Appendix A, General Design Criteria" and "CNP was designed and constructed to comply with the Atomic Energy Commission (AEC) General Design Criteria (GDC) as proposed on July 10, 1967". Therefore the licensee will be complying with the AEC proposed General Design Criteria to the CNP which is contained in the CNP Updated Final Safety Analysis Report (UFSAR) as the Plant Specific Design Criteria (PSDC) and differs from Appendix A of 10 CFR Part 50 GDC in both numbering and content. The PSDC applicable to this LAR are discussed below: PSDC 10 Reactor Containment The CNP UFSAR states: The containment structure shall be designed (a) to sustain without undue risk to the health and safety of the public the initial effects of gross equipment failures, such as a large reactor coolant pipe break, without loss of required integrity, and (b) together with other engineered safety features as may be necessary, to retain for as long as the situation requires the functional capability of the containment to the extent necessary to avoid undue risk to the health and safety of the public. PSDC 49 Reactor Containment Design Basis The CNP UFSAR states: The reactor containment structure, including openings and penetrations, and any necessary containment heat removal systems, shall be designed so that the leakage of radioactive materials from the containment structure under conditions of pressure and temperature resulting from the largest credible energy release following a loss-of-coolant accident, including the calculated energy from water or other chemical reactions that could occur as a consequence of failure of any single active component in the emergency core cooling system will not result in undue risk to the health and safety of the public.
3.0 TECHNICAL EVALUATION
CNP Units 1 and 2 containment buildings are reinforced concrete structures consisting of a vertical cylinder, a hemispherical dome, and a flat base slab. A steel liner is attached to the inside face of the concrete (shell, dome, and the base slab); the interior of the containment structure is divided into three compartments:
- An intermediate compartment that houses the energy absorbing ice bed (ice condenser compartment); and
- An upper compartment that accommodates the air displaced from the other two compartment volumes during an accident condition. The ice condenser is an insulated cold storage room in which ice is contained in a vertical cylindrical column. In an accident scenario, lower inlet doors located below the operating deck at the bottom of the ice condenser open due to the rise in pressure in the lower compartment. This allows steam to flow from the lower compartment into the ice condenser compartment. The steam is condensed as it enters the ice condenser compartment, thus limiting the peak pressure in the containment. The divider barrier between the upper and lower containment compartment is designed to carry the differential pressure between the lower and upper compartments during the postulated of-coolant accident. The divider barrier seal provides a pressure boundary between the lower and upper containment compartments of the containment structure and is located on the boundary of these compartments. The divider barrier seal is a structurally mounted flexible seal backed up by a steel plate that prevents the flow of steam and air from bypassing the ice condenser. The licensee's submitted amendment proposes to revise the SR 3.6.13.5.a as follows: Current SR 3.6.13.5.a: "Seal and seal mounting bolts are properly installed; and" Revised SR 3.6.13.5.a: "Seal and seal mounting connections are installed such that the total divider barrier bypass area is maintained within design limits; and" The proposed change to the SR 3.6.15.5.a involves two changes. The first proposed change to the SR replaces the word "bolts" with the word "connections". In an RAI, the NRC staff requested the licensee describe the types of connections and the procedure that will be used for verifying acceptable installation of these connections. On June 13, 2014, the licensee provided a response to SCVB-RAI-2 (ADAMS Accession No. ML 14167A374), stating the following: Procedures for performing the divider barrier seal surveillance contain design configuration criteria for the proper/acceptable installation of these connections. The criteria specified by the surveillance procedures include: bolt spacing, edge distances, number of connections, and tightness. The licensee also provided a response to STSB RAI-1C (ADAMS Accession No. ML 14167A374), stating the following: Seal mounting connections currently holding the divider barrier seal in place include bolts, screws, welded studs, nuts, welds, and concrete anchors. These connections are not specifically described in the UFSAR but are described on various CNP controlled design drawings, including but not limited to 1-2-3207E, 1-2-3207F, and 1-AEQS-226-A. Based on the NRC staff's review of the licensee's responses to SCVB-RAI-2 and STSB RAI-1 C, (ADAMS Accession No. ML 14167A374), the staff finds that the proposed change to the SR replacing the word "bolts" with the word "connections" is acceptable because the licensee describes connections used in CNP controlled design drawings in 1-2-3207E, 1-2-3207F, and 1-AEQS-226-A. Further, the licensee explains that they have procedures in place for performing the divider barrier seals surveillance for the acceptable installation of these connections. The proposed change to the SR 3.6.13.5.a also includes the requirement that the installed connections should maintain the total divider bypass area within the design limits. In RAI-3, the licensee was requested to describe the NRC-approved methodology that will be used to determine that the acceptance criteria for the bypass area are met. In a letter dated June 13, 2014 (ADAMS Accession No. ML 14167A374), the licensee stated the following: In case deficient connections are discovered, then the resulting divider barrier bypass would be determined, using an accepted standard, the American Institute of Steel Construction (AISC) Manual of Steel Construction, (tables for beam diagrams and formulas), as referenced in Updated Final Safety Analysis Report (UFSAR) Chapter 5, or using a simplified method that is more conservative, to determine the deflections of the as found configurations due to a postulated blowdown, and these deflections would be used to quantify the bypass area. The total bypass area for that unit is then compared against the Allowable Design Basis Bypass Area of seven square feet, per UFSAR 5.3.5.15.4. The assumed Analysis Value is 35 square feet, per UFSAR 14.3.4.1.3.1.1.e. After reviewing the above response, the NRC staff requested the licensee to explain: simplified method that is more conservative to determine the deflections of the as found configurations." More specifically, the licensee was requested to discuss the simplified method, the standard on which it is based, and the conservatism in the method. In a letter dated August 15, 2014 (ADAMS Accession No. ML 14230A678), the licensee stated, in part: "The simplified method is also based on the AISC standard." The licensee provided a pictorial drawing describing two cantilever beams, each attached at one end, with a uniformly distributed load (as referenced in the AISC Manual of Steel Construction 7th edition) to determine the assumed divider barrier bypass area. The NRC staff finds the licensee's responses acceptable because the assumed bypass area derived by using the simplified method based upon the pictorial drawing (two cantilever beams) would be approximately three times larger than the bypass area calculated by the exact AISC structural analysis method based on the fixed beam and thus would be more conservative. Based on its review, the staff finds that the proposed change meets the requirements of PSDC contained in the licensee's UFSAR, (1) PSDC 10, because the licensee showed that the containment design structure important to safety are not exceeded during an accident. The staff also finds that the proposed change meets the requirements of PSDC contained in UFSAR, (2) PSDC 49, because the licensee showed that the reactor containment structure and penetrations, with the aid of containment heat removal systems including the ice bed, are designed to limit radioactive fission products from the containment below 10 CFR 100 values. In addition, the NRC staff determined that the proposed modification does not change the intent of the surveillance requirements in SR 3.6.13.5.a and that the licensee will continue to meet the requirements in 10 CFR 50.36(c)(3). Therefore, the NRC staff finds the proposed license amendment to be acceptable.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Michigan State official was notified of the proposed issuance of the amendments. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendments change the requirements with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 or change the 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 (79 FR 9496). 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) there is reasonable assurance that 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.
