RESPONSE

The Philadelphia Electric Company does have an j

established long-term erosion / corrosion monitoring a

program for Limerick Generating Station (LGS), Units 1 j

and 2, and for Peach Bottom Atomic Power Station I

(PBAPS), Units 2 and 3.

The programs assure that the structural integrity of high-energy single-phase and two phase carbon steel systems is maintained.

The Limerick Generating Station Erosion / Corrosion Program is described in Specification P-508, " Nuclear Engineering Department Specification for Limerick j

Generating Station Units 1 and 2 - Program for Monitoring Pipe for Wall Thinning due to Erosion / Corrosion."

This specification is in place and being implemented.

It provides criteria for the following:

o Identifying the single phase and two phase lines to be included in the program.

o Selecting the single-phase and two phase inspection locations.

)

Determining the frequency of inspections.

o o

Determining appropriate acceptance criteria.

o Calculating the estimated remaining life of pipe and fittings.

o Determining the method of_ inspections.

o Determining necessary corrective actions.

I Furthermore, the LGS specification includes Appendices which:

This program is' in place and is being implemented.. The,PBAPS program provides~information similar to:what is.provided in the appendices of the LGS Specification; however, it does not provide the detailed engineering. criteria j

which is contained.in the LGS Specification._ In order to provideouniformity in. the programs at both' LGS and-

A common inspection procedure is used at LGS and'PBAPS T

for;the ultrasonic'(UT) detection of erosion / corrosion in piping systems. ;This procedure'is NDE-SP-3, "NDE Services Special Procedure for the Ultrasonic Detection?cf Erosion / Corrosion.in Piping Systems."
