Dear Dr. Murley:

This letter provides additional information regarding radiation monitoring systems as requested by a member of your staff.

The information supports our previous submittal AEP:NRC:0678Y, dated July 23, 1986, and is provided on the two attachments.

Attachment 1 is a description of how the gaseous radioactive effluent monitor readings are corrected for decay for the purpose of off-site dose calculation. Attachment 2 is a copy of an internal calculation to determine if the radiation monitor could survive in a post accident environment per IE Information Notice 86-30.

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

Very truly yours, M. . Al xich Vice President edg Attachments cc: D. H. Williams, Jr.

A. A. Blind - Bridgman R. C. Callen NFEM Section Chief G. Charnoff NRC Resident Inspector - Bridgman A. B. Davis - Region III 8910160287 891005 PDR ADQCK 05000315 P PNU

ATTACHMENT 1 AEP:NRC:0856X to AEP:NRC:0856X Page 1 The response of the Eberline SPING gaseous effluent radiation monitor (low-, mid-, and high-range channels) was calculated as a function of time for a postulated accident. The response of the detectors to the post-accident gas mixture was determined by utilizing the primary calibration efficiencies of each detector type. The result of the analysis provided tables of post-accident decay correction factors which can be applied to the radiation monitoring channels.

These correction factors had been inserted into and made part of our off site dose assessment computer code (DAP). DAP estimates off site doses to the whole body and thyroid resulting from plant releases.

The user is prompted to input the following information:

meteorological data, radiation monitor reading, time of reactor shutdown, duration of release, effluent flow rates, and the type of the accident that would be considered. During the process of calculating the estimated doses, the computer code automatically retrieves the gas mixture decay factor, which is a dimensionless multiplier, for the appropriate monitor reading.
