As part of an effort to develop human engineerging guidelines and a methodology for the evaluation of nuclear power plant control room operability, the Essex Corporation conducted T & E (test and evaluation) reviews of a wide sample of nuclear power plant control rooms. The objectives of these design reviews were: 1) selection, application, and development of human engineering evaluation guidelines applicable to the nuclear power industry; 2) selection and development of data collection and analysis procedures; and 3) identification of recurrent human engineering design problems in the control rooms of currently operating nuclear power plants. The present paper discusses the approach taken and the findings in item three above. Thirteen control rooms were visited, and guidelines and data collection methods under various degrees of development were applied. Following control room visits, data were analyzed according to usability, number of incidences of similar or identical operability design problems, criticality of problems with respect to both public and plant safety, and subjective assessment of operational affects due to human engineering problems in design. Results to date show that the following areas have recurrent operability design problems: layout of controls and displays according to either operational or functional use; coding of information for visual and auditory presentation; job performance aid and procedures design; communications; environmental factors such as ambient noise; violations in control and display conventions employed; use of conventions which violate population stereotypes; and failure to design within anthropometric constraints. Further work is being conducted by Essex Corporation to identify critical human engineering deficiencies in control room design and to select adequate yet cost-effective and corrective backfits.

Few human engineering standards or criteria for the design of nuclear power plant control rooms existed prior to the accident at Three Mile Island — Unit 2. For the most part control room design was dictated by electrical criteria, costs, and, most importantly, by precedent evolved from fossil fuel plant experience. Since the TMI-2 accident, the Nuclear Regulatory Commission has undertaken an ambitious program to develop control room design and operational guidelines to be used by utilities in evaluating the human engineering fitness of control rooms and in identifying human engineering problems requiring backfit. The following paper reviews the method used to develop control room guidelines, the process suggested to the utilities for performing control room evaluations, and sources for and the content of guidelines. As reported in the paper, evaluation guidelines evolved from a basic set of military standards and checklists through a series of on-site control room reviews. The methods used in these reviews involve surveys, checklists, and videotaped walk-throughs of emergency procedures. The final product is a Guidebook containing: (a) procedures for scheduling, planning, administration, and staffing of human engineering reviews; (b) the evaluation procedures to be used, including guidelines, human engineering data, references, and methods; (c) a trade-off process for sorting out problems needing immediate vs. more remote attention; and (d) suggestions for backfits for the human engineering problems most widespread in the industry.

The practicing human factors engineer is often called upon to help in improving a system which has already been designed, built and placed into operation. The authors' organization has recently completed a major program to develop guidelines for enhancing nuclear power plant control rooms. On the basis of this and other experiences, an outline for the process of enhancing a system has been developed. This paper will discuss elements of this process which lead to a comprehensive and systematic approach to improvement.

Practical methods and procedures which decrease the amount of time required to conduct an evaluation can be invaluable to human factors specialists as most are usually limited by economic and time constraints. Presented are the hypotheses that 1) the amount of effort required to collect survey data using checklist procedures is related to the quantities of controls and displays and is relatively independent of the system's operational complexities, and 2) the amount of effort required to conduct task analyses is related to the number of operators involved and the number of different ways in which operators interface with equipment, and is relatively independent of control and display quantities once these quantities reach a certain level. Procedures for collecting large quantities of data using checklists are described and the results of applying these procedures in a nuclear power plant control room where control board components exceeded 4000 instruments are discussed. The procedures used involved; 1) the development of a photographic mock-up of the control board, 2) serial numbering all components, 3) preparing component record sheets and discrepancy report forms prior to the evaluation, 4) modifying traditional checklists to a new format, and 5) revising the data collection methods for checklists.
