Abstract:

A Failure Modes, Effects and Criticality Analysis FMECA is used to determine, for the ANGRN-27V, the probability of radiation of hazardous signal and the probability of a loss of signal. This analysis is based on the FMECA performed on the Texas Instruments, Incorporated Mark III and the GRN-27. The methodology considers the effects of all failures of functionally distinct circuits which can result in potentially hazardous failure modes. Possible modifications to operating procedures and equipment are considered with respect to meeting the proposed Level 3 and Level 4 reliability levels. The reliability resulting from such improvements is calculated and a description of recommended improvements is included. Facility Maintenance Logs for the calendar year 1981 from GRN-27 facilities are analyzed and correlated with the theoretical calculations. Author
