SUBJECT:
Explanation of the TMI Effluent Assessment Group Monthly Su-ary a)
General
-Reference is made to the Executive S e ary entitled "TMI Units I and II Liquid and Gaseous Releases".
For purposes of comparison, all previous 1980 releases are included in this report. All data is given in monthly increments with quarterly averages or totals as applicable.
1)
Liquid Releases Line (a) gives all liquid releases except Tritium.
Since Tritium cannot be effectively removed from liquids, it needs to be separated out so that is can be carefully watched.
Tritium may very well be the critical radionuclide for liquid releases during the entire recovery process as well as during nor=al plant operations. Present Tech Specs for discharge of liquids, excluding Tritium and Noble Gases,,
is 10 Ci per reactor in any quarter year.
Line (b) separated the Iodine-131 released since it was the major radionuclide released during the early days of the accident and it will be found periodically in downstream drinking water supplies because of the periodic discharge from hospitals using Iodine-131.
The 10CFR20 allowable Iodine-131 release rate'is 3x10-7pCi/cc and the EPA drinking water standarsi is 3x10-'uci/cc (as averaged over one year).
Line (c) utilizes units of ifCi/cc for Tritium so that the release concentrations can be compared to the 10CFR20 limits of 3x10-spCi/cc.
Note that the EPA drinking water standard is 2x10-spCi/cc (as averaged over one year).
