Subject:
IE Bulletin No. 80-03, Loss of Charcoal from Standard Type II, 2 Inch, Tray Adsorber Cells R. E. Ginna Nuclear Power Plant, Unit 41 Docket No. 50-244
Dear Mr. Grier:
In response to NRC IE Bulletin No. 80-03 an inspection of the charcoal filter cells has been completed at Ginna Station.
The inspection was conducted in accordance with a procedure which is consistent with the standard given in Section 5 of ANSI N510-1975.
The exception to this is the Spent Fuel Pool Charcoal Filter which was tested
.per section 12 of ANSI N510-1975.
This was because it was not feasible to visually inspect the cells in this unit.
A tabulation of the systems involved, cell manufacturer and type, and observed cell condition is provided in the attachment.
Very truly yours, L. D. White, Jr.
