ccordance with NUREG-0711. Simulator • The ISV is conducted using a plant-referenced simulator that meets the functional and fidelity requirements of the adopted ANSI/ANS 3.5, “Nuclear Power Plant Simulators for Use in Operator Training and Examination,” and is capable of real time, high fidelity plant simulation of the BTP 7-19 software CCF concurrent with an AOO/PA. o The simulator accurately represents digital I&C CCFs and digital failure modes. o The plant-referenced simulator used for the validation of manual operator actions demonstrates expected plant response to operator input and to normal, transient, and accident conditions to which the simulator has been designed to respond. o The plant-referenced simulator is designed and implemented so that it is sufficient in scope and fidelity to allow conduct of the evolutions associated with AOO/PA, including manual operator actions, as applicable to the design of the reference plant. • The simulator accurately represents the HSI available and the postulated HSI failure(s) for the software CCF condition. Personnel • Participants in the validation are the plant personnel who would normally perform the credited actions. 18-A-10 Rev. 0 – November 2009 • Actions to be performed by licensed operators are validated using individuals holding a current operating license for the unit on which the actions are to be credited. • Actions allocated to non-licensed operators are validated using non-licensed personnel trained in accordance with a program that meets the requirements of 10 CFR 50.120. • The MCR operating staff size and composition used in the event simulations are the same as was used for the analysis and preliminary validation. • All crews are included as part of the ISV. Operational Conditions • Event simulations for the ISV include a range of representative CCF and digital failure modes, postulated HSI failures, and operational conditions in which credited actions may be required.
