[en] For several years the Susquehanna boiling water reactors (BWRs) operated by Pennsylvania Power and Light have had their reactor recirculation transients monitored using a computer system called GETARS, which stands for General Electric Transient Analysis and Recording System. This monitoring system has been very useful in analyzing and trouble shooting these reactor recirculation transients because of the availability of data recorded from GETARS. Had GETARS not been available, some recirculation problems would not have been resolved as effectively as they were. A few examples of the more significant and more recent reactor recirculation transients that have occurred and that were monitored by GETARS at Susquehanna are discussed in this paper
