Limited human factors engineering assessment of the 242-A Evaporator system: For input to the Safety Class 2 Systems/Structure assessment

摘要

Prior to the startup of the 242-A Evaporator system, members of the Pacific Northwest Laboratory (PNL) Human Factors Engineering staff conducted an assessment of the controls and monitors related to the issues classified as Safety Class 2 Systems/Structures. The purpose of this assessment was to determine the adequacy of the controls and monitors in ensuring safe operations of the Evaporator system, and the results were described in a Letter Report dated April 5, 1991. The ensuing comments/recommendations of Westinghouse Hanford Company operations, safety, and management personnel formed the basis of additional human factors activities that resulted in this report. 4 refs.
