MPQAP-2017-0001 incorporates limited alternatives to portions ofNQA-1 Subpart 2.2 which provide MOX Services the option to perform evaluations to identify and implement the appropriate preventive maintenance requirements during construction. These alternative preventive maintenance requirements, in conjunction with component installation inspections, component IROFS functional testing and post system turnover maintenance and surveillance requirements provide reasonable assurance that IROFS components will be reliable and available upon demand to perform their credited IROFS function during operation. Similar alternatives to the NQA-1 preventive maintenance requirements have already been approved for use at several Part 50 reactor facilities. Additional supporting information is included in the justification within the Enclosure.
NRC review and approval of MPQAP-2017-0001 is requested by February 28, 2018 in order to support ongoing project activities.
If you have any questions, please feel free to contact me at (803) 442-6485 or Dealis Gwyn, Licensing and Nuclear Safety Manager at (803) 819-2780.

- a. Section 3.2.1 (second sentence): During a period of layup after release of an item from storage, vendor recommendations for preventive maintenance, or an engineering evaluation or an engineering requirements document delineating appropriate maintenance requirements will be followed. Engineering evaluations and engineering requirements documents will consider vendor recommendations.
Justification of the changes is provided in the following sections.
Item 1 - MPQAP 19.2.3 Clarification Clarification that deviations from vendor recommendations for preventive maintenance (PM) will be documented aligns MPQAP 19.2.3 with the proposed change to the commitment to the second sentence in NQA-1, Subpart 2.18, Section 3.2.1. Since change is made to be consistent with the source requirement (NQA-1, Subpart 2.18), this change is a clarification and does not result in any reduction of commitments.
Item 2(a) NQA-1 Subpart 2.2 Applicability and Receipt Inspection The caveat regarding applicability during operations was deleted for clarification. The deletion of the caveat does not result in the reduction of any commitments.
The and in the compliance statement for Subpart 2.2 is interpreted to mean, in general, inspections are performed both prior to shipment and at receipt, but not necessarily at both locations for all SSC. The addition of and/or provides more clarity to the location of the performance of the receipt inspections is optional but does not result in the reduction of any commitments.
Items 2(b) and (c) NQA-1 Subpart 2.2 Sections 6.4.2 and 6.5 Alternatives
MOX Project Quality Assurance Plan (MPQAP)
AMENDMENT Docket No. 070-03098 Page 6 of 24 Amendment No. MPQAP-2017-0001 The alternatives to NQA-1 Subpart 2.2 Section 6.4.2 and 6.5 provide MOX Services the flexibility to identify and implement the appropriate preventive maintenance requirements during the construction phase of the project considering engineering requirements documents, engineering evaluations and vendor recommendations.
While economic factors can be a consideration in developing these requirements, the established PM requirements, in conjunction with previously established management measures, will ensure that that IROFS reliability and availability is maintained. The evaluations may identify requirements to refurbish or replace some components prior to operations based on actual storage or installation life and selected PM requirements (i.e., if operations date exceeds time interval, it may be more efficient use of project resources to refurbish or replace an component when compared to PM costs of extended storage/installation). While PM requirements are an important factor in IROFS reliability and ability, they are only one aspect. Additional factors include:
Maintaining appropriate environmental conditions during storage Checks/inspections prior to component installation Checks/inspections prior to component testing Testing to demonstrate capability to perform IROFS safety function prior to system turnover to operations Periodic maintenance after installation after system turnover to operations Periodic surveillance testing to demonstrate IROFS safety function performance after system turnover to operations
MOX Project Quality Assurance Plan (MPQAP)
AMENDMENT Docket No. 070-03098 Page 7 of 24 Amendment No. MPQAP-2017-0001 These factors along with documented evaluations that establish the appropriate preventative maintenance requirements during construction provide reasonable assurance that IROFS components will be reliable and available upon demand to perform their credited IROFS function.
In addition, the MOX Services alternate approaches to NQA-1 Subpart 2.2 are consistent with established NRC precedence for reactors, which are also required to establish 10 CFR 50 Appendix B QA programs. Examples of similar approved alternative approaches are provided in Attachment 1. Cases where it could be clearly identified that the accepted alternative was applicable during the construction phase are identified. is not intended to be complete list nor is it intended to demonstrate all the facilities that used this option during construction (i.e., actual number of facilities that used the approved NQA-1 Subpart 2.2 may be larger than the table identifies). Attachment 1 demonstrates that the MOX Services alternate approach to a portion of NQA-1 Subpart 2.2 is similar to approaches previously accepted by the NRC. The common theme in that MOX Services reinforces with its amendment is a focus on commitments to perform documented engineering evaluations for preventive maintenance.
Preventive Maintenance Requirements Engineering requirements documents are the primary means of conveying preventive maintenance requirements. Engineering evaluations are performed, as required, based on the complexity and criticality of the structures, systems, and components in installed storage (storage) or extended layup (layup). Vendor recommendations for preventive maintenance, where applicable, are considered in the determination of engineering requirements for maintenance requirements.
During the construction phase, the project is determining layup and storage requirements to support IROFS reliability and availability while also considering the following:
MOX Project Quality Assurance Plan (MPQAP)
AMENDMENT Docket No. 070-03098 Page 8 of 24 Amendment No. MPQAP-2017-0001
- a. Risk reduction (future limitation of cost due to repairs or replacement)
- b. Property protection
- c. Limiting conditions that cause equipment degradation As part of the process to transition to operations but prior to placing IROFS into service, MOX Services verifies that IROFS are capable of performing their credited safety function. This verification includes verification the IROFS have been installed in accordance with the design, IROFS will performed their safety function, preventive maintenance activities have been performed, and a preventive maintenance program has been established to support continued IROFS reliability. If there are IROFS components or parts of an IROFS, that have exceed their service life, the parts or components will be refurbished or replaced, as necessary, to support IROFS reliability and availability during operations.
Preventive maintenance programs address three aging categories Preventive maintenance programs have the goal of ensuring the reliability and readiness of the assemblies and components under their care when they called upon. Reliability is a term that applies to assemblies and components in service. Assemblies and components must be kept in a state that allows them to reliability perform when placed into service. Readiness is a term that applies to assemblies and components waiting to go into service. Readiness is the capability of assemblies and components to go from an inactive out-of-service state to an active in-service state. Categorizing preventive maintenance by aging mechanism is one way that preventive maintenance programs effective manage the care of complex assemblies and components to ensure their reliability and readiness.
MOX Project Quality Assurance Plan (MPQAP)
AMENDMENT Docket No. 070-03098 Page 9 of 24 Amendment No. MPQAP-2017-0001 Complex assemblies comprise a multitude of different components. Each assembly and each component within the assembly is subject to different aging mechanisms that determine whether the assembly falls under one of the following three aging categories:
- a. Infinite lifetime (i.e., no apparent aging effects)
- b. Finite lifetime with periodic renewal (i.e., preventive maintenance)
- c. Finite lifetime with no effective renewal process (i.e., replacement is required)
Preventive maintenance programs use engineering evaluations to determine the appropriate preventive maintenance requirements for assemblies and components. Engineering evaluations are used to identify the applicable aging mechanisms and to categorize assemblies and components into bins. The engineering evaluations provide the means to effectively target preventive maintenance where such maintenance assures the continued reliability and readiness of the assemblies and components.
Some assemblies and components are best kept dry, clean, sealed up, and periodically monitored for signs of deterioration. The hands-off approach precludes inadvertent degradation of components that have an infinite life except through wear by excessive manipulation, e.g., O-ring seals on access covers.
Some assemblies and components require periodic preventive maintenance. These assemblies and components may contain pieces that have finite lifetimes and require periodic renewal, e.g., batteries, lubricants.
Some assemblies and components may just age and require replacement, e.g., electrolytic capacitors.
Preventive maintenance on components with finite lifetimes would be ineffectual.
MOX Project Quality Assurance Plan (MPQAP)
AMENDMENT Docket No. 070-03098 Page 10 of 24 Amendment No. MPQAP-2017-0001 Thus, the proposed change strengthens the effectiveness of the preventive maintenance to be performed by committing to documented engineering evaluations that evaluates and determines effective preventive maintenance requirements for the assemblies and components. The proposed change does not reduce the commitment to perform preventive maintenance. The commitment to documented engineering evaluations assures long term reliability of the assemblies and components by ensuring preventive maintenance is effectively targeted.
Common cause failures caused by not following vendor recommendations Complex assemblies and components may have specific vendor recommendations for preventive maintenance that may be considered excessive during layup and storage. If these preventive maintenance activities are not performed the potential to have reliability issues in the future may exist, but these reliability issues are not certain. Startup testing is performed to ensure systems, structures, and components perform as specified. If issues are found during startup testing the systems, structures, and components are repaired, retested, and if they pass, then placed into service. At no time are systems, structures, and components allowed to be placed into service without assurance that they will perform as expected. These issues are specific to each assembly and component and should not be considered common to all assemblies and components.
The converse situation is also not a certainty. Guarantees of performance could not be given to systems, structures, and components, even if all of the vendor recommended preventive maintenance activities were performed. Preventive maintenance activities by their nature may be a cause of inadvertent damage to the component or to adjacent or related assemblies and components not undergoing the preventive maintenance activity. In order to preclude future reliability conditions, things like access covers have to be removed and replaced without damage. Adjacent components have to be disassembled and reinstalled to allow access to the components being maintained and to restore the assembly to whole. Errors performed in the disassembly
MOX Project Quality Assurance Plan (MPQAP)
AMENDMENT Docket No. 070-03098 Page 11 of 24 Amendment No. MPQAP-2017-0001 and the reassembly are points in the process where the act of providing preventive maintenance could be detrimental and the lack of preventive maintenance beneficial. It is clear that balancing preventive maintenance requirements ensures long term reliability and readiness of the assemblies and components.
Layup and storage requirements differ from operating requirements Preventive maintenance requirements are determined by engineering as part of the determination of layup and storage requirements. Periodic inspections and lubrication of components requiring lubrication are performed in accordance with a desktop procedure for preventive maintenance of equipment oil/grease reservoirs, which is based on successful practices from the reference facility, for example. These practices, by necessity, consider but may not follow vendor recommendations because of the unique process and nuclear safety requirements imposed by the design. Lubricating materials may differ from specified materials during layup and storage as a result of the nature of the equipment in a dormant state and the cost of the material.
During layup and storage some lubricating materials are known to be deliquescent and/or become gummy and rust promoting when left in a static condition in the humid atmospheric conditions at the site. Adherence to vendor recommendations in these instances could cause more harm and are best avoided. This strategy relies on final inspections and tests that are performed as part of commissioning to verify performance of the structures, systems, and components prior to turnover to Operations and startup. Material will be refurbished and/or replaced as required at that time.
Inconsistencies in vendor recommendations for similar equipment Vendor recommendations for preventive maintenance intervals and preventive maintenance actions varies with each product and each vendor. Variations in requirements are found between products offered by a single vendor and across multiple vendors that offer similar products, such as, manually operated ball valves.
For example, ball valve Vendor A makes no recommendations for long term storage of their product, while ball
MOX Project Quality Assurance Plan (MPQAP)
AMENDMENT Docket No. 070-03098 Page 12 of 24 Amendment No. MPQAP-2017-0001 valve Vendor B recommends multiple full stroke actuations every x months. The safety function of these ball valves is to maintain the confinement barrier, i.e., not leak. None of the valves have a safety function associated with actuation. Engineering makes the decision regarding which requirement is appropriate for the valves. If maintaining the valves in the equivalent of their new in box state is deemed more appropriate for maintaining the safety function, then periodic actuation of some of the valves to maintain an operability function becomes less of a priority.
Safety Significance of preventive maintenance during Construction The project is in Construction. Construction means the availability of alternative maintenance mechanisms that would not be optional when equipment is contaminated. Construction also means utility systems that are designed to have certain performance envelopes during Operations may not have the same characteristics during Construction because of temporary construction needs. These performance criteria include electrical power supplies, which may be negatively affected by heavy construction users, e.g., noise introduced by welding machines. Structures, systems, and components are not energized, have not been turned over to operations, and no special nuclear material is in the plant. Unlike structures, systems, and components in an operating facility, structures, systems, and components in Construction are not capable of nor will they be required to replace operating engineered safety features to prevent or mitigate any event sequences. The capability of the structures, systems, and components to prevent or mitigate event sequences will be demonstrated during cold startup testing but prior to turnover to operations. At which time, items requiring replacement will be replaced as required to ensure the performance during operations, including the performance of safety functions. For the long term reliability and readiness of the assemblies and components the preventive maintenance program needs to take into account the project phase.

AMENDMENT Docket No. 070-03098 Page 13 of 24 Amendment No. MPQAP-2017-0001 Summary While efficient use of project resources is a consideration in establishing preventive maintenance requirements, the MOX Services alternatives to portions of NQA-1 Subpart 2.2 continue to provide reasonable assurance that IROFS will be reliable and available during operations and is consistent with previously NRC approved alternatives for nuclear facilities during construction and operation. Preventive maintenance requirements are one factor supporting IROFS reliability and availability; additional factors include maintaining appropriate layup and storage environment, testing that demonstrates performance of IROFS safety functions prior to operations and preventive maintenance activities and surveillances demonstrating IROFS operability during operations.
