  • July 24,.. l987

SUBJECT:

WATER CHEMISTRY SURVEY OF SELECTED PWR PLANTS

~: -.

As a result of the Surry pipe erosionicorrosion incide~t 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 understanding of erosion/corrosion in pipes is an accurate assessment of erosion/corrosion 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 ::chemfstry"ictions Jn pressurize'd water reactors.

To accompl i sti..,..

this task we ask that you complete the enclosed questionnaire.

We recogn*ize that some of this information has also*been requested by NRC Bulletin *No. 87-01.

To ensure completeness, please transfer that information to this response also, as appropriate.

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 not in a convenient format which is readily accessible.

Therefor, we request that you assist us by returning for each unit a single completed copy of the enclosed questionnaire to the Project Manager, U. S. Nuclear Regulatory Commission, Washington, 0. C.

20555, within 60 days of receipt. of this letter.

We believe the questionnaire is self explanatory; however, if questions arise or clarification is required, please contact your NRC Project Manager.
