DPR-58 and DPR-74 NUREG-0737, XI.F.1-1 NOBLE GAS MONITORING SYSTEM TECHNICAL REPORT Mr. Harold R. Denton, Director Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Denton:

Per Item III of our letter AEP:NRC:0678S, dated February 19, 1986, enclosed is the Eberline Instrument Corporation technical report titled "PING/SPING Particulate, Iodine and Noble Gas Monitor Detector System Technical Specification."

11 of this report is to discuss the current noble gas monitoring 1

The purpose system at the Donald C. Cook Nuclear Plant with respect to NUREG-0737,Section II.F.1-1. For each channel of the noble gas monitor, the report contains detailed information on the detector system mechanical design, sensitivity, range, linearity and energy response and methods of primary and user calibration.

We believe, based on this report, that the noble gas monitoring system meets the requirements of NUREG-0737,Section II.F.1-1. Therefore, we request concurrence from the NRC that the detector's range capability, sensitivity, and linearity are sufficient and that further primary calibration of our system is not necessary.

This document has been prepared following Corporate procedures which incorporate a reasonable set of controls to insure its accuracy and completeness prior to signature by the undersigned.

Very truly yours, PDR P . 'DR 8604210103 860414 ADOCK 05000315I P. Alexich ~ $

Eberline CORRORA7ION Post Office Box 2108 Santa Fe, New Mexico 87504 2108 Phone: (505) 471.3232 TWX: 9109854678 Telex: 660438 Elc SFE October 31, 1986 Mr. Jim Leichner American Electric Power Service Corporation 1 Riverside Plaza Columbus, OH 432164631 RE: SPING TECHNICAL SPECIFICATIONS

Dear Mr. Leichner:

This letter is submitted in r<<sponse to your request for verification that the February 1986 report entitled "PING/SPliVG Particulate Iodine and Noble Gas Monitor Detector Systems T<<chnical Specification" is applicable to the SPING monitors installed at D.C. Cook.

I have reviewed the contents of this report anil can state that the DC. Cook SPING monitors, while not having the full cor>>plement of options discussed in the report, are still capable of meeting the r<<quiremcnts of NUREG 0737 as discussed in section I of this report. The in;t~llation of the solid-state mass flow sensor option does not change the linearity, energy response or sensitivity of the monitoring channels.

I will point out that Eberlin<<has spent almost two years collecting additional data on these detector systems to better understand their response to gamma and beta radiations over a ivide range of energies. When this data has been completely evaluated. the Technical Specification report in question will be revised and re-issued. In particular the energy response of the beta scintil-lation detector will be chang<<d significantly. Some of the reported sensitivities of gas channels may also cltattge. These revisions, which should be available in early 1987, are not expected to affect the applicability of these monitors with respect to NUREG 0737. The final report should give users the necessary information to better predict the detector response to various gaseous isotopic mixtures.
