SUBJECT:

RANCHO SECO 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 research 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.

The information being requested is quite extensive and will require a diligent effort on your part and ours to assure accurate and timely completion. Also, we

)

realize that parts of the information may already be available to the NRC, but i

not in a convenient format which is readily accessible. Therefore, we request that you assist us by returning the completed copy of the enclosed questionnaire to the Project Manager, U. S. Nuclear Regulatory Commissicn, Washington, D. C.

20555, within 60 days of receipt of this letter. We believe the questionnaire is self explanatory; hcwever, if questions arise or clarification is required, please contact your NRC Project Manager.
