Operation of EBR-II has required that issues of safety and reliability be continually addressed. This has been necessary not only to support routine operation, but also to support test programs that bear upon safety. Major issues are: (1) operability of fuel elements with breached cladding (local fault prevention); (2) assurance of adequate convective cooling upon loss of pumping power (decay heat removal); and (3) demonstration of benign response of fuel-elements and subassemblies to protected overpower transients (shutdown system margin and reliability. Test programs to address these issues at EBR-II are described. Particular emphasis is given to the potential capability at EBR-II for mild transient testing, consistent with its role in addressing LOA-1 (line of assurance one) safety issues.
