Plant management has not completely understood the impact of this deferral as we are near the end of the interval for both units. The ISI Program was not properly maintained for several years from what was apparently management lack of interest. The ISI group is in the rebuilding process at this time, with several people being hired to handle it adequately. No examinations have been missed, but there is discussion on what should be included in the program. There were too many people making decisions without anyone being held responsible.
Undocumented modifications are a problem.
Existing plant drawings are poor and out of date. There is a program to get them updated, but the program does not include letting the ISI Coordinator know when the drawings have been updated with new information. The previous software was not adequately supported by the vendor and had so many problems it was almost impossible to use. The new software is also made by a vendor, but has been around since the beginning of ISI computing. It is called WinISI 2000.
