Dear Mr. Cockfield:

ACRS (10)

SUBJECT:

TROJAN EROSION / CORROSION QUESTIONNAIRE As a result of the Surry pipe erosion / corrosion incident in December of 1986, the NRC is preparing a report that will reference existing resecrch information available and describe the actions being taken by utilities regarding erosion /

corrosion in feedwater pipes in nuclear power plants. Central to an understand-ing of erosion / corrosion in pipes is an accurate assessment of erosion /corrison experience, piping design, feedwater and condensate chemistry and piping materials.

To ensure that both the NRC and the nuclear industry have available a comprehensive collection of data regarding erosion / corrosion in feedwater pipes, the NRC will assemble a summary of utility information related to ongoing water chemistry actions in pressurized water reactors. To accomplish this task we ask that you complete the enclosed questionnaire.

I The information being requested is quite extensive and will require a dilig nt effort on your part and ours to assure accurate and timely completion. Als >, we realize that parts of the information may already be available to the NRC, bct q not in a convenient format which is readily accessible. Therefore, we request  !

your assistance by returning a completed copy of the enclosed questionnaire 4 within 60 days of receipt of this letter. We believe the questionnaire is self explanatory; however, please contact me if questions arise or clarif-ication is required.
