FW: Steam Generator Flow Limiters B2.1.7 Boric Acid Program question re: valve packing, etc.

RAI response is in 12/5/08 letter Attachment 1 pages 23-36 and Follow-up question response is in 2/6/09 letter pages 5-6.

Cycle histograms I looked at the histograms. The entries for 1973, 1983 and 1992 for Unit 1and 1975 and 1992 for Unit 2 just indicate the unit was shut down at the end of the calendar year. Therefore the cumulative numbers of startups and shutdowns would be equal. If the unit were operating, there would be one more startup than shutdown.
