Preliminary maintainability analysis of the HTGR dry head-end reprocessing systems

A preliminary maintainability analysis was prepared for the HTGR dry head-end reprocessing systems. Most probable failure modes, failure mechanisms, corrective maintenance requirements and failure rates were identified for each of the systems. Maintainability network diagrams were prepared to identify all operations required to correct the failures. Maintenance activities were summarized, and major downtime contributors were identified for future design upgrading to reduce downtime.
