SUBJECT:

Arkansas Nuclear One - Units 1 a 2 Docket Nos. 50-313 and 50-368 License Nos. DPR-51 and NPF-6 Water Chemistry of Pressurized Water Reactors -

Arkansas Nuclear One - Units 1 and 2

Dear Mr. Calvo:

The attached information is provided in response to the request contained in your correspondence of July 15,1987 (9CNA078711).

Our submittal was discussed with the AN0 Project Manager on October 14, 1987. During that discussion it was determined that since the retrieval of-chemistry history data earlier than 1982 would require a substantial effort. -

the inclusion of that information with this submittal would not be required.  !

In accurdance with that discussion, we have provided the. requested data to I correspond to the period from-1982 to the present. '

L If you have any questions regarding this' information, please co'ntact my office, j Very truly yours, t

J. Ted Enos, Manager j Nuclear Engineering and Licensing l-JTE/HWT/sd Enclosure 9002010203 871113 gDR ADOCK05000g3 jpol;
