"Aspects of the Human Factors Engineering Design not Verified During Verification and Validation," says, "Aspects of the HFE design that are not addressed in the HFE verification and validation include modifications to the standar d design and the HFE aspects that cannot be performed in the simulated environment. This may include design characteristics, such as new or modified displays for plant-specific design features. Features that may not be accurately simulated include

• ergonomic considerations, such as lighting and background noise.

• HSIs outside the MCR but within the plant HFE program scope, including the TSC, RSS, EOF, and certain LCSs."

Please clarify which LCSs are considered "certain LCSs" as discussed in

FSAR Tier 1, Section 3.15.1, "Design Description," says, "The HSI of the technical workload is assessed."FSAR Tier 2, Section 18.1.1.4, "Applicable Facilities," contains the same statement. The "Human Factors Engineering Program Management Plan" (HFE PMP), is incorporated by reference in FSAR Tier 2.2.2.3, "Applicable Facilities," says, The scope of the NuScale HFE program includes the alarms, controls, indications, and procedures applicable to the main control room (MCR) and the remote shutdown station (RSS). The HSI at the RSS are derived from the HSI in the MCR. The HSI of the TSC, the EOF, and local control stations (LCS) are also included implicitly since their HSI are derivatives of the MCR HSI. The EOF and the technical support center (TSC) will comply with the guidance of NUREG-0696, Functional Criteria for Emergency Response Facilities. The HSI in the TSC and EOF are derivatives of the MCR HSI and comply with the HSI style guide; however, these HSI are for information display only. No control functions are provided in any of the emergency response facilities. For these facilities, the program scope is limited to defining the plant data and their HSI impact on licensed operator workload.
