Subject:
McGuire Nuclear Station, Unit 1 Docket No. 50-369 LER/R0-369/83-07 l
Dear Mr. O'Reilly:
My letter of March 2,1983 submitted reportable occurrence report R0-369/83-07 which concerned T.S.3.3.3.9, "The Radioactive Gaseous Effluent Monitoring Instrumentation Channels shown in Table 3.3-13 shall be operable...".
As part of the corrective actions given in the report Duke committed to replace the charcoal filtern for iodine detectors on a monthly basis to prevent buildup of excessive dif ferential pressure. However, changing these filters monthly is ineffective in that except for the following two conditions which can occur at any time new or old charcoal cartridges are essentially the same:
(1) large or rapid increase in counts or count rate, and (2) loss of flow to the EMF package. Therefore, the charcoal filters for iodine detectors will be changed under those conditions rather than monthly.
Very truly yours, ff.b. ?4Lc-lh Hal. B. Tucker PBN:glb cc: Document Control Desk U. S. Nuclear Regulatory Commission Washington, D.
