'.fATERTCW2T ARSENAL CO REPORP NO. 47/67-1 I continue to be favorably impressed with the operation of this facility.
C'Connor tells me that, in making a ccntain=ent leak rate test, he reads the differential =ano=eter to 1/20.
He further stated that he could probably decrease the leak rate con-siderably if he did a preliminary test, fi::ed leaxs and t'ren did a final test.
Most of the leaks are xnewn to be around the airlccks - sechanical penetra:1cna and seals.
To date, the tests have been made with all equipment in an as-is status, and the results have always been belcw Hazard Surnary Report and technical specliication limits.
O'Ccnnor is presently dickering with DE for a 5 :N li::ense.
I have not been successful in persuading him to test the absolute l
filters.
DE =ay wish to censider requiring such a demonstration.
