ns are formal, effective, and timely. Rationale Guidance for HFE analyses that would be suitable to support the event analyses is described in NUREG-0711. The NRC staff has a high degree of confidence that a licensee/applicant using the NUREG-0711 model will provide adequate HSI design to allow operators to accomplish the manual actions required by their designs. However, the typical HFE Program per NUREG-0711 does not conclude until just before fuel load or startup. This attachment provides guidance for a methodology that provides early feedback in the design and regulatory review process and allows the licensee/applicant to move forward with relative confidence that credited manual operator actions will be demonstrated as both feasible and reliable in the ISV. Ultimately, the ability to reliably perform credited manual operator actions will be verified through completion of ITAAC or license conditions related to the actions credited in the analyses. Furthermore, the ability to reliably perform the credited manual actions within the time available shall be maintained through a long-term monitoring strategy. 18.0-28 Revision 3 – December 2016 Additional Resources • Manual actions – General • Consistency in NRC's Treatment of "Manual Actions" Across Regulatory Applications (ADAMS Accession No.ML111960336) • Manual actions associated with common cause failure of I&C software • Branch Technical Position (BTP) 7-19, “Guidance for Evaluation of Diversity and Defense-in-Depth in Digital Computer-Based Instrumentation and Control Systems.” • DI&C-ISG-05, “Task Working Group #5: Highly-Integrated Control Rooms — Human Factors Issues.” • Manual actions associated with fires • NUREG-1852: “Demonstrating the Feasibility and Reliability of Operator Manual Actions in Response to Fire”. • Regulatory Guide 1.62: “Manual Initiation of Protective Actions.” REFERENCES 1.
