UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 September 11, 1992 Docket No. 50-530 Mr. William F.

Conway Executive Vice President, Nuclear Arizona Public Service Company Post Office Box 53999

Phoenix, Arizona '5072-3999

SUBJECT:

PRELIMINARY SPECIAL STUDY REPORT ON HUMAN PERFORMANCE IN OPERATING EVENTS A preliminary special report by the NRC Office for Analysis and Evaluation of Operational Data (AEOD) entitled "Human Performance in Operating Events" is enclosed.

The study describes potentially generic observations and conclusions based on onsite evaluation of 17 operating events.

Due to the length of the draft report, a copy of this letter and the enclosed preliminary report has been placed in the Local Public Document Room, located in the Phoenix Public Library, Business and Science Division, 12 East McDowell Road

Phoenix, Arizona 85004 for public review.

To briefly review for your benefit, each study was conducted by a multidisciplined team, led by an AEOD staff member, with additional NRC headquarters, regional and Idaho National Engineering Laboratory personnel.

The studies focused on those factors that helped or hindered operator performance.

The team usually spent 1 to 3 days on site interviewing plant personnel and gathering records.

Individual reports of each site study were prepared and distributed within the NRC, to the site involved in the study, and to certain industry groups and a copy was placed in the Public Document Room.

This special study describes generic observations and conclusions drawn from 17 such studies.

We believe these events represent an estimated one-fourth to one-third of the events which significantly challenged operating crews during this 2 I/2-year period.

Six studies were performed in 1990, seven in 1991 and four in 1992.

Ten events occurred at pressurized water reactor plants (PWRs) and seven events occurred at boiling water reactor plants (BWRs).

Eleven events occurred at power and 6 occurred in standby or shutdown mode at 16 plant sites.

Four studies were performed as part of an augmented inspection team effort, while 13 were performed solely under AEOD auspices.

In accordance with our "peer review" process, prior to the finalization and distribution of our special study report, we are providing you, various industry groups, experts in the field of human factors and plant management where these events occurred with a copy of the preliminary report for review and comment.

We request that you focus your review primarily on the accuracy and completeness of the observations and analyses contained in the report.
