Subject:
Cleanup of Aux Luilding and Contairzent Tnere is a high priority to obtain breathing room for water storage capacity in the Aux Building.
Obviously we cust avoid becoming completely constipated.
However, the physical activity for ion exchulge resin systems should be inr.talled and operated in a separate outside building.
This should be basically cell with re=cte capability to uncouple and recouple ion exchange resin a n't tants.
An evaporator system should also be outs yde tre Aux Building and the Reacter contcirrent.
This may sound far fetched b 4 ); is highly certain that if the cleanup is dcne inside the Aux Building i: will be pernanently cc m aminated to a level which n y sell preclude reactor cperations in the future cat te "Alars."
As a strong recommendation, the Lighly ccntarinated water should be f.rst passed through filters and ion exc%nge te reacre the aierity of the activity.
This will allow subsequent operation to be n i reted by essentially
" hands on".
The concentrated activity can then be implaced in concrete shielding and sent off site.
It is irperative that in the rush "to do scrething" that a terrible long tem probler is not created for Met-Ed operations of the plant in the future.

SUBJECT:
LEAK FROM VENT HEADER OR SQMEPLACE AND POTENTIAL PROBLEM WITH ACCESS MOLE 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.
Information - HPR 3240 is located on elevation 328' between the air handling ecuiprent of the fuel handling area.
HPR 3240 is approxicately 20 ft. from the air handling eauipment from the Auxiliary Building.
Area monitors and background survey indicate high levels (> 10 R) in a major part of tne Auxiliary Builoing.
This limits severely the ability to get direct data.
Effort - HPP 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 from 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 scme cf the release.
(Seals,etc.)
P Need - Background survey (update) and monitor equipment on the Auxiliary Building I
exhaust system.
