The sensor is a sole IROFS [Item Relied On For Safety] for a particular sequence. Criticality controls remained in place. Affected equipment has been shut down. No unsafe condition exists. Feed tube level sensor is in place for the sequence to limit mass. At no time was the mass limit exceeded. We are reporting under Part 70, Appendix A, (a)(4) which states that credited IROFS must remain available and reliable. We cannot evaluate reliability in the time required for a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> report.
