Obiettivo
THE GENERAL OBJECTIVE OF THE BENCHMARK EXERCISE ON HUMAN FACTORS IS TO ASSESS THE DEGREE OF CONSISTENCY OF METHODS AND RESULTS AND TO IDENTIFY CONSENSUS IN ANALYSIS PROCEDURES.
THE OBJECTIVE OF THE ANALYSES IS TO DETERMINE:
A) THE UNAVAILABILITY BECAUSE OF THE TEST ASSUMING A CORRECT SYSTEM
B) THE PROBABILITY THAT AFTER THE TEST INITIAL (SINGLE-) FAILED COMPONENTS ARE NOT RESTORED, AND THE IMPACT OF MISCALLIBRATION.
C) THE PROBABILITY OF AN OPERATIONAL TRANSIENT PROVOKED BY FAILURE OR ERROR OF THE OPERATOR.
THERE ARE FOUR EMERGENCY FEED WATER SYSTEMS IN THE REFERENCE PLANT, SO COMMON CAUSE FAILURES MUST BE CONSIDERED UNDER A). THE NATURE OF THE ANALYSES WILL BE QUALITATIVE AND TIME-BASED.
