Tenorm Avoidance Via Throughput Margin

Direct answer: When a resin's own manufacturer states a TENORM (Technologically Enhanced Naturally Occurring Radioactive Material) accumulation threshold, the safe design pattern is setting the regeneration throughput setpoint at a large conservative safety margin below that threshold (a real ~5.2x margin was used in the River Island project) rather than relying on downstream waste characterization alone to catch a problem after it has already occurred.
