Title	Moderation Control Item Relied on for Safety Degradation
Event Description	During an investigation of an unusual sinter test measurement result, it was determined that one of the Items Relied On For Safety (IROFS), as documented in the [Integrated Safety Analysis] (ISA) summary, had degraded. This report is submitted for administrative reporting pursuant to 10 CFR 70.50 Appendix A (b)(2). The IROFS described for the moderation control of the powder additive at the Dry Conversion Process (DCP) blender operation did not function as required because of an error that occurred at the Dry Scrap Recycle (DSR) container transfer station. At no time did an Unsafe condition exist. The existing criticality safety analysis of the operation bounded the situation, was effective and was not challenged. The container transfer station operation is shut down pending completion of an investigation and implementation of corrective actions.
