Fitness for duty in the nuclear power industry. Volume 3, Annual summary of program performance reports, CY 1992

Abstract

This report summarizes the data from the semi-annual reports on fitness-for-duty programs submitted to the NRC by 52 utilities for two reporting periods: January 1 through June 30, 1992, and July 1 through December 31, 1992. During 1992, licensees reported that they had conducted 266,551 tests for the presence of illegal drugs and alcohol. Of these test, 1,818 (.68%) were confirmed positive. Positive test results varied by category of test and category of worker. The majority of positive test results (1,110) were obtained through pre-access testing. Of tests conducted on workers having access to the protected area, there were 461 positive tests from random testing and 178 positive tests from for-cause testing. Follow-up testing of workers who had previously tested positive resulted in 69 positive tests. For-cause testing resulted in the highest percentage of positive-tests; about 26% of for-cause tests were positive. This compares to a positive test rate of 1.06 percent of pre-access tests and .29 percent of random tests. Positive test rates also varied by category of worker. Overall, short-term contractor personnel had the highest positive test rate at 1.00 percent. Licensee employees and long-term contractors had lower positive test rates (.29% and .63%, respectively). Of the substances tested, marijuana was responsible for the highest percentage of positive test results (50.3%), followed by cocaine (24.8%) and alcohol (22.6%). Positive test results are also reported for NRC administrative regions and for plants located in areas with different rates of population density.
