| − | The reliability of plant systems and components is critical to the continued safe and effective operation of nuclear plants. NMAC develops guidelines and technical reports that offer technically sound maintenance strategies and practices, enabling nuclear plants to take actions that can improve equipment reliability and reduce operations and maintenance costs. The information produced by the NMAC can be used to ensure safe and reliable operation of nuclear power plants for the benefit of the people that work at the plant and the general public.

| − | *Equipment Issues and Maintenance Guides: Maintenance strategies, fully informed by operating experience and technology advances, can improve equipment reliability, lower operating costs, and increase overall plant reliability. This program area identifies and addresses important maintenance and equipment issues through our interactions with users groups, technical advisory groups, nuclear plant visits, vendor interactions, university relationships, and other industry sources. Through these relationships and interactions we produce technical research reports and software tools that provide relevant technical information for addressing key maintenance issues, troubleshooting guidance, preventive and predictive maintenance strategies, as well as outlining new technology that can assist in equipment maintenance. | + | * [https://peer.epri.com/ PRR - Electrical] |
| − | *Engineering and Maintenance Procedures: Bringing essential information to the point of decision-making can help support safe and reliable plant and fleet performance. Access to equipment information and personnel knowledgeable in engineering and maintenance practices can offer useful perspective and input. Information and industry experience is collected through various users groups, meetings, plant visits, assessments, and failure analysis reviews, and then infused into regularly published technical reports and guidelines that address new or improved methods and processes to enhance nuclear plant performance and improve equipment reliability. | + | * [https://pr.epri.com/ PRR - ER Processes] |

| − | Research focus areas containing multiple common projects have been developed to document and guide research activities. NMAC"s five research focus areas are: Component Guidance, Innovative Technology, Maintenance and Engineering Practices, Condition Monitoring Technologies, and Maintenance Strategies.
| + | =Revision Control= |
| | + | Only EPRI staff can edit wiki content. Each wiki page that has technical content has a revision number (at the top of the page) and a record of revisions (at the bottom of the page). The record of revisions summarizes technical changes made for each revision. Minor, editorial changes may be made without changing the revision number. |
| | | | |
| − | ==Accomplishments==
| + | When substantive technical changes are made to a page, or new pages are added, member review may be obtained, consistent with the Technical Advisory Committee/Group (TAC/TAG) process used for developing other EPRI products. Since changes are made "live" within the wiki environment, a version that is currently in review will have "in review" following the revision number. Pages or revisions that are in review should be considered preliminary until the review is complete and the "in review" has been removed from the revision number. |
| − | NMAC distills global operations and maintenance experience into actionable guidance for nuclear plant systems and components. Lessons learned from nuclear plants around the world are incorporated into industry technical guidance.
| |
| − | •Developed two tools to support Value-Based Maintenance (VBM). The first tool provides enhanced visualization of industry equipment work order data; the second tool provides a cost module to interface with component templates in EPRI"s Preventive Maintenance Basis Database (PMBD). The tools work together to inform the development of maintenance strategies that consider both equipment reliability and the cost of maintenance activities.
| |
| − | *Upgraded the Preventive Maintenance Basis Database software to inform the determination of optimum replacement and refurbishment times. The upgrade features a "Vulnerability Tool" that can assess changes in preventive maintenance (PM) strategies and identify which failure modes may change with PM changes. Also added the capability to evaluate lower-cost alternative strategies in support of a Value-Based Maintenance (VBM) approach.
| |
| − | *Developed the theory and design conditions necessary for the creation of a seal for water-circulating pumps in nuclear power plants that could control leakage by adjusting its shape while in use. This new seal design, when implemented, could increase plant reliability, reduce plant shutdowns, and lower maintenance costs. A patent on this new seal technology is pending in the United States.
| |
| − | *Provided guidance on various lubrication issues: reducing water content in lubricants, additives, fluid testing, EHC servo valve maintenance, and extending lubrication intervals through technology.
| |
| − | *Provided ongoing knowledge transfer on the following:
| |
| − | **Freeze Sealing (ice-plugging)
| |
| − | **Multi-stage Horizontal Pumps
| |
| − | **Mobile Application for Rigging and Lifting Practices
| |

Revision Control
Only EPRI staff can edit wiki content. Each wiki page that has technical content has a revision number (at the top of the page) and a record of revisions (at the bottom of the page). The record of revisions summarizes technical changes made for each revision. Minor, editorial changes may be made without changing the revision number.
When substantive technical changes are made to a page, or new pages are added, member review may be obtained, consistent with the Technical Advisory Committee/Group (TAC/TAG) process used for developing other EPRI products. Since changes are made "live" within the wiki environment, a version that is currently in review will have "in review" following the revision number. Pages or revisions that are in review should be considered preliminary until the review is complete and the "in review" has been removed from the revision number.
