SUMMARY

OF NOVEMBER 13, 1986 MEETING TO DISCUSS HUMAN FACTORS / OPERATOR BURDEN REVIEWS On November 13, 1986, the NRC staff met with representatives of the BWOG. The purpose of the meeting was to discuss the human factors / operator burden aspects of the BWOG reassessment program. is a list of the meeting attendees. Enclosure 2 is a set of handouts provided by the BWOG. The BWOG summarized the areas in the existing Safety and Performance Improve-ment Program projects that consider the operator interface. These projects include the sensitivity study being performed by MPR Associates, ICS/NNI system review, operating experience review, main feedwater system review, operations / maintenance personnel interviews, and procedures review. A new operator burden project is being proposed by the BWOG. The objectives of this project are to develop a means of comparing the difficulty or complexity of risk significant operator actions on different plant types and to compare the operator burden at B&W plants relative to the operator burden at Westinghouse plants. The methodology to be used will select appropriate transients, determine the critical operator actions required, determine the time available to perform the actions, and determine the time needed to perform the actions. Analytical data on the selected transients will be reviewed to determine the analyzed times for key operator actions. The transients will be performed on a simulator and the time needed for key operator actions will be measured. The BWOG plans to define the project details early in December and to develop a project schedule by January 8, 1987. The NRC staff expressed a concern that no human factors professionals have been involved in the BWOG reassessment program. The NRC staff indicated that they are reviewing the BWOG Transient Asse'ssment Program reports on transients at B&W plants to determine'whether operator mind set adversely affected operator performance. The staff indicated that they will share the results of this work with the BWOG. In addition, the staff indicated that the Office of Nuclear Regulatory Research plans to contract with INEL to do a program similar to that which the BWOG is proposing. The staff will discuss this program with the BWOG when it is defined and approved by NRC management. Concurrence by NRC management is expected in December. hk-Walter A.

The purpose of the meeting was to discuss the human factors / operator burden aspects of the BWOG reassessment program. Enclosure 1 is a list of the meeting attendees. Enclosure 2 is a set of handouts provided by the BWOG. l The BWOG summarized the areas in the existing Safety and Performance Improve-ment Program projects that consider the operator interface. These projects include the sensitivity study being perfomed by MPR Associates, ICS/NNI system review, operating experience review, main feedwater system review, operations / maintenance personnel interviews, and procedures review. ~ A new operator burden project is being propcsed by the BWOG. The objectives of this project are to develop a means of comparing the difficulty or complexity of risk signift: ant operator actions on different plant types and to compare the operator burden at B&W plants relative to the operator burden at Westinghouse plants. The methodology to be used will select appropriate transients, determine the critical operator actions required, determine the time available to perfonn the actions, and determine the time needed to i perform the actions. Analytical data on the selected transients will be reviewed to determine the analyzed times for key operator actions. The transients will be performed on a simulator and the time needed for key g' operator actions will be measured.
