Other reactors of similar design, called pressurized water reactors, have had steam generator problems.
Mr. Smeloff, a former utility executive, listed Maine Yankee, in Wiscasset, Me., and Trojan, near Portland, Ore., where, he said, steam generator problems "convinced management to close the plant".
Steam generator problems have caused major economic losses in terms of lost electricity production through forced unit outages and, in cases of extreme damage, as additional direct cost for large-scale repair or replacement of steam generators.
San Onofre Unit One shut in the 1990s due largely to steam generator problems.
He also reported that due to generator problems he was shutting off his radio for some time.
This study shows that it is possible to realize the ambitious aim of same day evaluation of lead and generator problems, but this intent may be influenced by engineering differences, transmission frequency and methods of alert notification.
Changes in clinical follow up methods are required to maintain early reaction ability The trial shows that same day evaluation of lead and generator problems is possible but is affected by engineering differences, transmission frequency, methods of alert notification, and workflow patterns.
In this work, the influence of different random number generators, problem dimensionality, and number of function evaluations on the optimization efficiency of Differential Search algorithm is presented in detail.
