APS, to G.

W. Knighton, NRC, dated December 18, 1984 (ANPP-31502).

Dear Mr. Knighton:

As discussed with the staff on December 21, 1984 we are providing the justifi-cation for changes made to CESSAR Tables 9.3-1, 10.3.4-1 and 10.3.4-2 which were previously submitted by Reference (1).

Also, as requested by the staff, we are providing a description of the materials used for the transfer lines and pump components in contact with hydrogen (CESSAR 7.16.4.3).

Please contact Mr. William Quinn of my staff if you have any questions.

Very truly yours, EEVB/TFQ/mb E. E.

Removal of oxygengcontrolled fn the reactor coolant and steam generators by employ fng hydrogen

Control of suspended Solids in the Steam generator fs shifted ta the frater and CondenSate (Tab'fe 10,3,4-2) wherein control limits are in effect for total iran and tetany copper.

10.3.4-2 Oeletion of abnormal I <mits Control Of abnormal conCentrations of impurfties in the feekrater and condensate systee is shf fted to the steam generator (TabIe 10.3.4-1) as the approprfate control point for tea generator protectton.

This guidance is in aecovrfsnco with the PMA secondary voter chemi~fry guidelines issued by the EF RI Steam Generator owners Group.

10.3.4-2 deletion of wmonka 10nkts Centra~ of wnmon$ o is substituted Hath control limits on pH and total iron and copper tO prevent OorrosiOn pl'OVUCtS from entering ti.e steam generator, 10.3.4-2 Oeletion Of SiliCa Control of silica

ile TYGON does contain chloride, it is covalently bonded (rather than'onic) and is therefore not available for leaching.

Thus, this material is suitable for hydrazine service.
