Subject:

Dresden Station Units 2 and 3

NRC Dkts. 50-237, ¢o'.'""2!__ 50-254,.

and 50--265

Dear Mr. Silver:

Attached is the subject dat;.a_surrunarized in graphic form for an 11-month period of 1973. The data shown is representa-tive of the -normal water che6is~ry during t~~ operating history o*f the subject reactors. Additional data is availa.ble for NRC review at the respective stations.

Also attached are excerpts from the GenE;!ral

• Elec.tric, Sargent & Lundy, and Graver chemistry specification *applicable to the subject units.

With respect to dissolved oxygen specifically, we have only scant data .for reactor water. The data we have, however, glves no*indication that our.BWR's are any-different than any others.** That is, the dissolved oxygen values are less than 0 .3 ppm at operating conditions. Such value~ were verified and are documented in the General Electric startup test re~orts.

One (1) signed orig.inal and 39 copies of this data are provided .for your information.

• Very truly yours, .
