Dear Mr. Kintner:

Attached to this latter 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. If any additional-information or clarification is required, please contact L. E. Schuerman. Very truly yours, Yf W. F. Colbert Technical Director Enrico Fermi'2 WFC:ca Attachment cc: G.

SUMMARY

OF CORRECTIVE' ACTION / ADMINISTRATIVE JONTROL The'Radchem Engineer or his delegate is responsible for: (1) the interpretation and recording of. data, (2) investigative analysis, (3) identification of problem sources, and (4) recom-mendations to -control / minimize detrimental effects to reactor water and to.the System. . Specific guidelines are outlined below: Power ~ Operation When the reactor water conductivity exceeds a control point of 0.7 pS/cm, increased sampling and investigative analysis.will be performed to identify the source and control / minimize its effects..If reactor water conductivity is>1.0 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 uS/cm and trending upward during startup/ hot standby, in-creased sampling and investigative analysis will be performed to identify the source and control / minimize its effects. If reactor water conductivity is12.0 pS/cm during startup/ hot standby, op-erations will continue as outlined in Enrico Fermi 2 Technical Specification Section 3.4.4. I Copper The control point for Copper (Cu) in reactor water is 40 ppb. -If previous samples indicate an upward trend, increased sampling l and investigative analysis will be performed to identify the source and control / minimize copper input. The number of excursions be-yond the 40 ppb control point will be identified in the annual report. -,a w..,, ** T- -5
