This report is available on the U.S. Nuclear Regulatory Commission (NRC) public web site within the Agencywide Documents Access & Management System (ADAMS) public document subdirectory under Accession No. ML15083A205. INTRODUCTION This attachment provides a methodology to identify high-workload operational conditions and analyze the workload associated with them. The methodology is rooted in task analysis and relies on the identification of appropriate challenging scenarios, realistic portrayals of task performance that is complicated by separate, but often necessary, dependent and independent tasks, and the judgment of subject matter experts (SME) obtained in a manner conducive to obtaining realistic workload
