Development and demonstration of surveillance and diagnostics of rotating machinery for reducing radiation exposure to nuclear power plant personnel. Annual technical progress report, October 1, 1980-September 30, 1981
This report describes the technical progress that resulted during fiscal year 1981 in the rotating machinery monitoring program being conducted at Grand Gulf Nuclear Station (GGNS). This program is designed to reduce radiation exposure to power plant personnel resulting from inspection, maintenance, and repair of rotating equipment. The plant is in the process of performing hot functional testing and expects to begin loading fuel in February 1982. Essentially all of the monitoring software and hardware is complete and integrated testing of the monitoring system will proceed when data links between plant computers are fully operational. The monitoring software has been upgraded to incorporate some new displays and an alignment program. There have also been several improvements directed at making the system easier to use and more understandable to an inexperienced user. Several documents have also been prepared to describe the use of the system and to define the internal structure of the software that has been developed. All of the monitored trains except the reactor recirculation pump and the reactor feed pumps have been operated for some period during FY-81. Baseline data have been recorded and analyzed on 16 of the 26 trains in the monitoring program. This involves data from over 100 vibration probes during steady-state and transient conditions. This report also presents a discussion of a survey of literature related to occupational radiation exposure and of the radiation accounting system being implemented at GGNS. Two other utilities were visited to ascertain the availability and the format of their exposure data, and the findings of these visits are presented.
