1. RELEASE OF INDIVIDUAL NOBLE GAS ISOTOPES FROM THE PLANT STACK WAS DETERMINED USING AN ISOTOPIC ANALYS!$ AT THE STE AM JET AIR EJCECTOR. XE133, XE135, KR85M, KR 88, KR87, AND XE13B WERE MEASURED AND USED TO CHARACTERIZE THE MODE OF GAS RELE ASE FROM THE FUEL. OTHER $1GNIFIC ANT NDBLE GASFS WERE DETERMINED USING KNOWN RATIOS,-THE MEASURED TOTAL OFFGAS HOLDUP SYSTEM DELAY TIME, AND THE KNOWN FRACTION OF THE OFFGAS STREAM RELE ASED VI A THE GL AND EXHAUSTER.
2. AN ISOTOPIC ANALYSIS FOR NOBLE GASES IS NORMALLY NOT POSSIBLE AT THE BUILDING VENTS. THEREFORE, FOR VENT RELE ASES, THE ISOTOPIC MIXTURE IS ASSUMED TO BE EQUAL TO THE MIXTURE DETERMINED AT THE SJ AE.
3. TOTAL RELEASES REPORTED IN T ABLES 1 A AND 2A 00 NOT INCLUDE NUCLIDES WHICH WERE BELOW MINIMUM DETECTABLE ACTIVITY (MDA). MDA VALUES ARE INCLUDED IN TABLES 18, 1C, AND 28. COMPARISONS OF RELEASES TO APPLICABLE LIMITS DO -

NOT INCLUDE NUCLIDES WHICH WERE BELOW MDA. MAXIMUM ALLOWED HDA VALUES ARE ESTABLISHED IN THE TECHNIC AL SPECIFIC ATIONS.
