Reactor Water Sampling,iAnalysis, and Administrative Control

Dear Mr. Kintner:

~

Attached to this letter are Reactor Water Sampling and Analysis parameters and a summary of Chemical Administrative Controls for reactor water main-tenance.

Reactor water copper will have an admin-istrative trigger point of 40 ppb.

In addition, Feedwater copper will have an administrative trig-ger point of 0.6 ppb.

kfanyadditionalinformationorclarificationis required, please contact L. E. Schuerman.

REACTOR WATER SA!!PLING AND ANALYSIS SUMtARY OF CORRECTIVE ACTION / ADMINISTRATIVE CONTROL The Radchem Engineer or his delegate is responsible for:

(1) the interpretation and recording of data, (2) investigative analysis, (3) the identification of problem sources, and (4) re-commendations to the Nuclear Shif t Supervisor to control / minimize detrimental eff ects to reactor water and to the System.

Specific guidelines are outlined below:

Power Operacion When the reactor water conductivity exceeds a control point of 0.7 pS/cm, increased sampling and investigative analysis (eg; Feed-water, Reactor water, Demineralizer Influent, pH and condenser leak determinations) will be performed to identify the source and control /

minimize its ef f ects. If reactor water conductivity is ll.0 pS/cm operations will continue as outlined in Enrico Fermi 2 Technical Specification Section 3.4.4.

Startup/ Hot Standby If reactor water conductivity exceeds a control point of 1.3 pS/

cm and trending upward during startup/ hot standby, increased sa=pling and investigative analysis (eg; Feedwater, Reactor water Deminerali-zer Influent, pH and condenser leak determinctions) will be performed to identify the source and control / minimize its eff ects.

Il r eactor

')

water conductivity is 2 2.0 pS/cm during startup/ hot standby, operations will continue as outlined in Enrico Fermi 2 Technical Specification Section 3.4.4.

Copper

~

The control point for Copper (Cu) in reactor water is 40 ppb. If previous samples indicate an upward trend, increased sampling and f nvestigative analysis (eg; Feedwater, Reactor water, Demineralizer In-Cluent and pH determinations) will be performed to identify the source and control / minimize copper input. The number of excursions beyond the 40 ppb control point will be identified in the annual report.
