Many nuclear power plants in the United States have recently been granted a 20 year extension to their operation license and are considering modernization. The Idaho National Laboratory is committed to successful modernizations and has been identifying and developing candidate technologies for power plants using methods that match the requirements of an integrated system validation. To do so this paper discusses current and potential workload, situation awareness and other performance methods used in evaluating control room design against the criteria defined by the Nuclear Regulatory Commission. The analysis provided is narrowed to the scope of methods surrounding the Light Water Reactor Sustainability research at the Idaho National Laboratory and therefore evaluates only a handful of the numerous methods used in control room modernizing efforts. As such, it was determined the most popular methods for measuring situation awareness, workload, and performance are measurements that rarely measure their intended construct directly and must be inferred. Physiological measures of workload have matured and become more accessible, sensitive, unobtrusive, valid, and objective but are reliant on variable technology. Situation Awareness measures possess little construct validity but eye-tracking technology is a measure progressing in sensitivity, objectivity, and continues to improve in unobtrusiveness. All things considered, this paper has identified a significant need for a more extensive review of the various performance measures used in modernizing control rooms and integrated system validation.
