Preventive Maintenance Program The Calvert Cliffs Nuclear Power Plant (CCNPP) Preventive Maintenance (PM) Program has been established to maintain plant equipment, structures, systems, and components in a reliable condition for normal operation and emergency use, minimization of equipment failure, and extension of equipment and plant life. The program covers all PM activities for nuclear power 8

FIRST ANNUAL AMENDMENT TO APPLICATION FOR LICENSE RENEWAL plant structures and equipment within the plant, including the Auxiliary Building H&V System components within the scope of license renewal. [Reference 17] Guidelines drawn from industry experience and utility best practices were used in the development and enhancement of this program.

Calvert Cliffs MPM0 1159, Inspecf/Lubricate Spent Fuel Pool Exhaust Fan Filter Bypass Damper, is currently performed every 6 months with Repetitive Task 00322003, which directs the user to inspect the damper gasket material for signs of deterioration. [References 18, 19] This inspection would discover elastomer degradation and/or wear of the damper seal gasket material if it were occurring. Corrective actions are taken in accordance with the CCNPP Corrective Actions Program.

The plant maintenance program has numerous levels of management review, all the way down to the specific implementation procedures. For example, there are specific responsibilities assigned to BGE personnel for evaluating and upgrading the PM Program. [Reference 17] The PM Program has also undergone evaluation by the NRC as part of their routine licensee assessment actiVities. These assessments and controls provide reasonable assurance that the PM Program will continue to be an effective method of managing the effects of elastomer degradation and wear

• Existing routine PM activities to periodically inspect the Spent Fuel Pool Exhaust Fan Filter Bypass Dampers will provide reasonable assurance that the effects of elastomer degradation and wear on the damper gasket seals would be detected.

(#) - Indicates the Group in which this device type/ARDM combination is evaluated Note: Not every component within the device types listed here may be susceptible to a given ARDM. This is because components within a device type are not always fabricated from the same materials or subjected to the same environments. Exceptions for each device type will be indicated in the aging management section for each ARDM discussed in this report.

The following is a discussion of the aging management demonstration process for each group identified above. It is presented by group and includes a discussion on materials and environment, aging mechanism effects, methods to manage aging, aging management program(s), and aging management demonstration.

Group 1 (crevice corrosion, general corrosion, and pitting for duct and heat exchangers) - Materials and Environment Group 1 is comprised of components that are potentially exposed to moist air and condensation. These include the ducting where the steel materials are exposed to the potentially moist air. The duct, fittings, Application for License Renewal 5.11IA-10 Calvert Cliffs Nuclear Power Plant

APPENDIX A -TECHNICAL INFORMATION 5.11A - AUXILIARY BUILDING HEATING AND VENTILATION SYSTEM Elastomer degradation and wear are plausible for the flexible collars since the elastomers will degrade at the joints in the HVAC equipment due to relative motion between vibrating equipment, pressure variations and turbulence, and exposure to temperature changes and oxygen. These stressors will result in eventual tearing of the boot. Elastomer degradation and wear are plausible for damper seals because the neoprene will degrade due to relative motion between the blade and sleeve during damper operation and exposure to temperature changes and oxygen. These stressors will result in eventual breakdown of the seal.

[Reference 2, Attachment 6s] If left unmanaged, elastomer degradation and wear could eventually result in the loss of pressure boundary integrity of the duct flexible collars and damper seals under CLB design loading conditions.

Group 2 (elastomer degradation and wear for non-metallic duct and damper parts) - Methods to Manage Aging Mitigation: Elastomer degradation can be mitigated by utilizing materials that are less susceptible to heat and oxygen. Wear can be mitigated by minimizing operation of the dampers to slow degradation of the seating surfaces, which leads to a loss of leak tightness. [Reference 2, Attachment 7s]

Discovery: Periodic visual inspections can be performed for the Group 2 equipment to detect the effects of elastomer degradation and wear. Degradation of the flexible collars can be detected through periodic system walkdowns because the collars are readily accessible. Degradation of damper seals can be detected through continued inspections and walkdowns. If significant degradation is discovered, the flexible collars or damper seals can be repaired or replaced as appropriate. [Reference 2, Attachment 8]

Group 2 (elastomer degradation and wear for non-metallic duct and damper parts) - Aging Management Program(s)

Mitigation: The system was designed to minimize vibration by using equipment support isolators and equipment-to-duct isolators, such as the flexible collars. Changes to materials or to system operating practices are not deemed necessary to mitigate the effects of these ARDMs. Implementing the discovery methods discussed below are adequate methods to manage these ARDMs. Since there are no additional methods beyond these design features for mitigating elastomer degradation and wear, there are no programs credited with mitigating the aging effects due to these ARDMs. [Reference 2, Attachment 6s and 8]

Discovery:

Routine system walkdowns would discover elastomer degradation and wear of the duct flexible collars and possibly of the damper seals. To assure that degradation of the damper seals is not threatening the capability of the dampers to provide the pressure boundary function they will be included in a new ARDI Program.

System Walkdowns Procedure MN-1-319 provides for discovery of the effects of elastomer degradation and wear by providing for system walkdowns that include visual inspections, reporting the walkdown results, and initiating corrective action. Under this program, inspection items typically related to aging management include identifying poor housekeeping conditions (such as degraded paint), and identifying system and equipment stress or abuse (such as excessive vibrations, bent or broken component supports, etc.).
