Spray Pond Procedure

Dear Mr. Knighton:

The referenced letter provided you a copy of our spray pond monitoring program described in our procedure 73AC-9SPOl, "Spray Pond Piping Integrity Verification." In addition to the monitoring outlined in that procedure< APS will conduct a reexamination of the Diesel Generator Cooling and Essential Cooling Water Systems on PVNGS Units 1 and 2.

The scope of this reexamination is proposed as follows:

Examination Criteria o Unusual Rust Formation or Deposits o Tube Blockage o Excessive Pitting of Heat Exchanger Tube or Tube Sheets o Indicators of Stress Corrosion Cracking Co nents to be Examined o Diesel Generator Jacket Cooling Water Heat Exchanger o Essential Cooling Water Heat Exchanger o Accessable Piping at Heat Exchangers Examination Schedule o Unit 2 Train A or B Hot Functional Test (approximately late June 1985) Visual Exam o Unit 1 Train A or B First Refueling Visual Exam eso~ o<i
