Subject:
NRC I8E Bulletin No. 80-03 Loss of Charcoal from Standard Type II, 2 Inch Tray Adsorber Cells File:
D.4.01.1
'lO (Fcoilf[J MAR 84 1980
Dear Mr. Engelken:
We have reviewed the design of PVNGS in accordance with the concerns of NRC ISE Bulletin No. 80-03.
The subject Type II tray adsorber cells are not used on PVNGS.
The filtration units for PVNGS use rechargeable, permanent, single-unit adsorbers (PSU).
Perforated plates tach welded on 3/4" centers to the cell'housing are used on the PSU type adsorbers instead of a screen riveted to the housing.
Therefore, there should not be any separation or filter housing deformation to cause loss of charcoal and/or channeling.
Very truly yours, CC V~
