SUBJECT:
LEAX FROM VENT HEADER OR SO4EPLACE AND POTENTIAL PROBLEM WITH ACCESS HOLE TO MAKE-UP TANK Problem - Monitor HPR 3240 indicates gas evolution from the Auxiliary Building.
Since there is no hot fuel or activity in the Fuel Storage Building.
Infonnation - HPR 3240 is located on elevation 328' between the air bandling equipment of the fuel handling area.
HPR 3240 is approximately 20 ft. fren the air handling equipment from the Auxiliary Building. Area monitors and background survey indicate high levels (> 10 R) in a major part of the Auxiliary Building.
'Tiis limits severely the ability to get direct data.
Effort - HPR 3240 data are being plotted against plant manipulation, i.e., level in the make-up tank, pressure in the make-up tank, valve position of MU V13, (the outlet valve frcxn MT to vent header). Suggestion of other comparison would be desired from other.
Drawings of the MT are being obtained to review details in anticipation of reducing leak.
It is possible that degassing of liquid in the Auxiliary Building could cause some of the release.
(Seals,etc.)
Need - Background survey (update) and monitor equipment on the Auxiliary Building exhaust system.
