SPLB RAI Followup

Len, Following the call, Devender came by and asked that I followup with you on SPLB-A-28 (which will be renumbered as SPLB-A-27). He wanted to make sure that the response addresses whether the discussion in the following two sentences in Supplement 28, Attachment 1, page 10, "Suction pressure trip setpoint" paragraph applies to with runback or without runback:

"The minimum calculated RFP suction pressure following the trip of one CP at EPU will be approximately 124 psig. There is sufficient margin between the minimum transient RFP suction pressure and the current RFP suction pressure trip setpoint to ensure RFP operation during normal operation and the loss of one CP transient."
