MEMORANDUM TO:
Phillip McKenna, Acting Director Division of Reactor Oversight Office of Nuclear Reactor Regulation Meena Khanna, Acting Director Division of Risk Assessment Office of Nuclear Reactor Regulation FROM:
Brian Smith, Director Division of Risk Analysis Office of Nuclear Regulatory Research
SUBJECT:
RESEARCH INFORMATION LETTER (RIL 2022-11)
HUMAN PERFORMANCE TEST FACILITY VOLUME 5 The Office of Nuclear Regulatory Research (RES) is providing, for your information and use, Research Information Letter (RIL) report, Human Performance Test Facility (HPTF) Volume 5 (RIL 2022-11). This report presents a detailed re-analysis of the data reported in RIL 2022-11 Volumes 1-2 with the goal of developing a preliminary understanding of the performance and ergonomic differences between glass top and hard panel simulators.
Understanding the difference between glass top and hard panel simulators is important because:
(1) There is increased interest in using glass top simulators as an alternative to plant referenced simulators for licensing exams, training, and validation.
(2) New control rooms could be either partially or fully equipped with glass panels.
This re-analysis provides preliminary guidance and serves as a starting point for additional human performance studies with glass top simulators. Both this and the subsequent studies in this area are supported by UNR-NRR-2024-001 project 49, Regulatory Uses of Glass Top Simulators. The current study, like all HPTF studies was conducted after the Commission, in SRM SECY-08-0195, directed the staff to consider using generic simulator platforms for addressing human performance issues, as simulators provide a tool to gather more empirical nuclear specific human performance data. These experimental data enhance the current information gathering process and, therefore, provide stronger technical bases and guidance to support regulatory decision making.

RES has worked closely with NRR to ensure that the cognizant staff were aware of the results of the referenced research and how the products could be applied to ongoing and future regulatory activities prior to transmittal of the final report. All comments have been addressed with your staffs involvement. We expect that this close working relationship will continue.
RES has established an online quality survey to collect feedback from user offices on the usefulness of RES products and services. This survey can be found online at this hyperlink. RES would appreciate the responsible manager or supervisor completing this shortabout 5 minutessurvey within the next 10 working days to present your offices views of the delivered RES product.
