RESPONSE TO GENERIC LETTER 88-05 FOR THE PRAIRIE ISLAND NUCLEAR GENERATING PLANT UNIT NOS. 1 AND 1. (TAC NOS. 68940 AND 68941)

On March 17, 1988, the NRC staff issued Generic Letter 88-05, "Boric Acid Corrosion of Carbon Steel Reactor Boundary Components in PWR Plants". In this letter we requested that you prcvide assurances that a program has been implemented at your plant that addresses the corrosive effects of reactor coolant system leakage at less than technical specification limits, The e nt.ric letter identified four considerations which your program should include.

In a letter dated M6y 25, 1988, you 'esponded to Generic Letter 88-05, describing your commiuaent to a boric acid leakage monitoring end preventive program at your plant. We find that you have provided assurance that a program is in place dealing v'th boric acid leakage that potentially could affect the integrity of the reactor coolant pressure boundary. This fulfills your requirement in responding to Generic Letter 88-05.

As discussed in Genaric Letter 88-05, you should maintain, in auditable form, records of the program and results obtained from implementation of the program.

These records may be subject to future auditing.

This completes our effort under TAC NO. 68040 and 68941.

On March 17, 1988, the NRC staff issued Generic Letter 58-05, "Boric Acid Corrosion of Carbon Steel Reactor Boundary Componencs in PWR Plants". In this letter we requested that you provide assurances that a program has been ieplemented at your plant that addresses.the corrosive effects of reactor coolant system leakage at less than technical specification limits. The generic letter identified four considerations which your program should include.

In a letter dated May 25, 1988, you responded to Generic Letter 88-05, describing your commitment to a boric acid leakage monitoring and preventive program at your plant. We find that you have provided assurance that a program is in place dealing with boric acid leakage that potentially could affect the integrity of the reactor coolant pressure boundary. This fulfills yo'ir requirement in respanding to Generic Letter 88-05.

As discussed in Generic Letter 86 05, you should maintain, in auditable form, records of the program and results oi:tained from implementation of the program.

These records may be subject to future auditing.
