of 16 KEY FINDINGS – Phase I •
Technology developed for current PWRs can serve as a starting point for SMRs • SMR vendors agree that OLM must have a role in maintenance optimization of SMRs • SMRs must include provisions in their design for adoption of OLM during or after construction. • Additional research is needed to establish the reliability of OLM results for SMRs. See PHASE II.

of 16 WORK NEEDED – Phase II •
Establish provisions in SMR design for OLM integration • Develop Empirical and Physical Models for OLM monitoring SMRs • Customize / Validate OLM algorithms • Build Data Acquisition System for SMR’s • Evaluate the use of prognostics for real- time asset management • Build prototype OLM system for SMRs • Design a commercial OLM system for SMRs
