Waste Management 2024: The symposia at 50
This year marked the 50th anniversary of Waste Management Symposia’s Waste Management Conference, held March 10–14 in Phoenix, Ariz. The event has grown significantly since the first Waste Management Conference in 1974, which attracted about 200 attendees. This year’s conference saw a record attendance of around 3,300 people from more than 20 different countries and boasted 235 technical sessions and 89 exhibitors.

Mandatory safety-related design requirements for this type of equipment include essentially the absolute leak-tightness of the heat exchange surfaces separating sodium from water and the prevention of violent sodium-water reactions. After briefly recalling the various situations likely to give rise to leaks, their evolution (self-wastage), and consequences (wastage and secondary ruptures), the precautions taken during steam generator (SG) designing, manufacturing, and operating phases to minimize leak hazards and satisfy the mechanical design basis requirements adopted for secondary loop components are analyzed. The in-service monitoring systems provided (hydrogen detection, acoustic detection) and the means devised to keep leak consequence within acceptable limits (rupture disks) are described. The automatic or operator-controlled actions initiated by signals from these systems are reviewed (reactor shutdown, SG isolation pressure relief, cooling and inertization of sodium or water-steam circuits). Plant overhaul procedures, servicing operations on the SG itself (whipping tube localization, damage assessment on adjoining tubes by insertion of an eddy-current probe, removal of damaged tubes) and on the secondary loop after detection and prior to restartup are presented. For each device and situation mentioned, a comparison is drawn, underlining the fundamental differences existing in the different types of SGs and tube materials.
