1.0 INTRODUCTION
By letter dated July 14, 2003, (ADAMS Accession No. ML031990230), as supplemented December 5, 2003 (Accession No. ML033440414), and February 12, 2004 (Accession No. ML040500425), the Calvert Cliffs Nuclear Power Plant, Inc. (the licensee) submitted a request for changes to the Calvert Cliffs Nuclear Power Plant, Unit Nos. 1 and 2, Technical Specifications (TSs). The requested changes would change the Surveillance Requirement 3.6.6.8 to verify each containment spray nozzle is unobstructed only following maintenance that could result in nozzle blockage. The supplements dated December 5, 2003, and February 12, 2004, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the staffs original proposed no significant hazards consideration determination as published in the Federal Register on August 19, 2003 (68 FR 49814).
2.0 REGULATORY EVALUATION
Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix A contains General Design Criteria (GDC) for nuclear power reactors. In particular, GDC 40 requires that the containment heat removal system be designed to permit periodic testing. The containment spray system is included in the containment heat removal system.
The Combustion Engineering Standard Technical Specifications, NUREG-1432, Volume 1, Revision 2, dated March 2003, SR 3.6.6.A.9 specifies a testing frequency of 10 years for the nozzle blockage test. While this is not a requirement, it had been the Nuclear Regulatory Commissions (NRCs) and industrys judgment of an acceptable frequency for this test and this is the frequency currently required by the Calvert Cliffs Technical Specifications.
The NRC has approved, on a plant-specific basis, several revisions to this requirement. The revisions require verification that each spray nozzle is unobstructed only following maintenance which could potentially result in nozzle blockage. This is based on the judgment that once the
containment spray system nozzles are determined to be unobstructed, the only mechanism which can cause nozzle blockage is by foreign material introduced following maintenance when the licensees foreign material exclusion (FME) program is not effective. This is substantiated by operational experience, as discussed below.
3.0 TECHNICAL EVALUATION
The Calvert Cliffs containment heat removal system consists of the reactor containment fan cooler system and the containment spray system. The containment spray system actuates automatically on a high containment pressure signal or remote-manually from the control room.
The containment spray system has two safety functions. It removes heat from the containment atmosphere following a design basis loss-of-coolant accident (LOCA) or main steam line break accident inside containment. This reduces the driving force for containment leakage and ensures the containment structural limits are not exceeded. The containment spray system also removes iodine and other radionuclides from the containment atmosphere following a LOCA.
The containment spray system is described in Section 6.4, Containment Spray System, of the Calvert Cliffs Updated Final Safety Analysis Report (UFSAR). It consists of two independent 50% capacity trains with no common headers. The spray nozzles are made of corrosion resistant stainless steel and are of a hollow core, centrifugal-type design without any internal parts which could cause clogging. The system includes two spray headers. The Unit 1 containment spray system consists of 179 nozzles. The Unit 2 system consists of 180 nozzles.
The minimum area flow path in the containment spray system is the spray nozzle. The licensees July 14, 2003, letter states that the nozzle orifice will pass particles less than 0.375 inches in diameter.
Calvert Cliffs TS SR 3.6.6.8 currently requires a test every 10 years to ensure that the containment spray system nozzles are not obstructed. The test is currently done, according to the licensees July 14, 2003, letter, with the spray inlet valves closed. Low pressure air or smoke is blown through test connections downstream of the spray inlet valves and the movement of flagging confirms flow from each nozzle.
One postulated mode of blockage of the spray headers and nozzles is solid boric acid accumulation in the spray lines or nozzles due to evaporated borated water. This could occur following an inadvertent containment spray actuation. The spray headers are normally maintained dry and are isolated from the water in the rest of the containment spray system by a normally closed air operated control valve on each header. Any leakage through this valve is directed to the containment sump by a drain line. The containment spray system piping is corrosion-resistant stainless steel. Should there be inadvertent flow through the nozzles, such as a spurious actuation, the licensee would evaluate the need for remedial actions or flow testing.
The other possible blockage source is debris (foreign material) in the system. The licensees July 14, 2003, letter describes the Calvert Cliffs foreign material exclusion program. The program is consistent with expected standards for system cleanliness and provides high confidence that debris will not be introduced during times when the containment spray (CS) system boundary is breached for maintenance or testing.
3.1 Performance History at Calvert Cliffs The licensees July 14, 2003, letter describes the past testing done to ensure that the containment spray nozzles are unobstructed. Pre-operational tests were successfully conducted on both units. In addition, a successful test was performed on Unit 1 in 1994 and Unit 2 in 1997. The licensee states that no work has been done on the [containment spray system] header or nozzles since these tests. Maintenance work has been done on the portion of the system upstream of the containment spray header isolation control valve. This work was performed with FME controls in place.... In response to an NRC request for additional information, the licensee reported in a December 5, 2003, letter that there had not been any condition reports on incidents that would have affected nozzle flow since the last flow tests.
Based on the fact that it is unlikely that any foreign material has entered the containment spray system since the last surveillance test on each unit and based on the licensees FME program, the NRC staff finds the Calvert Cliffs operating experience acceptable for approving the proposed TSs change.
3.2 Industry Experience and Failure Mechanisms Review of industry experience using the NRCs Sequence Coding and Search System for Licensee Event Reports indicates that spray systems of similar design are not susceptible to plugging. The staff reviewed industry experience and found that, with a few exceptions, once tested after construction, containment spray nozzles have not been subject to blockage. There have been several exceptions. In the case of one pressurized-water reactor (PWR), a chemical added to the inner surface of a spray system pipe to eliminate corrosion detached and the loose material blocked some spray nozzles. Spray piping in PWRs, and Calvert Cliffs in particular, is corrosion resistant; therefore, this failure mechanism is not applicable to Calvert Cliffs. The licensee for another PWR found debris, identified as construction debris, in the spray nozzle headers. The fraction of blockage was not significant and the sprays remained functional. The debris was found by visual observation, not by an air flow test.
3.3 Conclusion of the Technical Aspects As a result of reviewing the licensees request to revise the testing frequency for the containment spray nozzles from 10 years to following maintenance which could result in nozzle blockage and reviewing and assessing all the applicable information provided by the licensee, the staff concludes that the design of the Calvert Cliffs containment spray systems, the past history of these spray systems, and the licensees FME controls provide reasonable assurance that the potential for nozzle obstruction is acceptably low. The FME controls provide reasonable protection from the introduction of foreign materials into open piping during maintenance or testing and require post-maintenance verification of system cleanliness and freedom from foreign materials. In addition, review of industry-wide experience has not demonstrated any problem with the licensees proposed change. Therefore, the staff finds the amendment request acceptable.
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. 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 (68 FR 49814). 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 Commissions 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.
