During a review of the Fuel Manufacturing Operation (
FMO) Integrated Safety Analysis (
ISA) it was discovered that controls associated with the container transfer station in the Dry Scrap Recycle (DSR) area had not been included in the updated
ISA Summary. Although process controls exist, they were not declared or documented in the
ISA as
IROFS (Items Relied on For Safety). This report is submitted for administrative reporting pursuant to
10CFR70.50 Appendix A(b)(1). 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.
All affected equipment is shut down pending revision of the ISA to document IROFS for this process.
While this did not result in an unsafe condition, this event is being reported pursuant with the reporting requirements of 10CFR70.50 Appendix A within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of discovery.
The licensee has notified Region 2 (Gibson) ,State, and local authorities.

The licensee provided the following information as a supplemental report:
A detailed review of authorized process equipment and controls was performed to ensure each has been evaluated in an ISA and the required IROFS have been identified. This review identified ten other processes with a valid criticality safety analysis that were not specifically documented as a part of an ISA evaluation and the required IROFS had not been identified. The ISA reviews for these have been completed and the required IROFS documented. A total of twelve new IROFS have been identified.
The licensee will inform the NRC Region 2 Office and the Headquarters Project Manager. Notified R2DO (Musser) and
FSME (Wastler).
