, ORTHERN STATES POWER COMPANY LICENSE NO. DPR-22 EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT NOTES:

1. RELEASE OF INDIVIDUAL NOBLE GAS ISOTOPES FROM THE PLANT STACK WAS DETERMINED USING AN ISOTOPIC ANALYSIS AT THE STEAM JET AIR EJCECTOR.

XE133, XE135, KRBSM, KR88, KR87, AND XE138 WERE MEASURED AND USED TO CHARACTERIZE THE MODE OF GAS RELEASE FROM THE FUEL. OTHER SIGNIFICANT NOBLE GASES WERE DETERMINED USING KNOWN RATIOS, THE MEASURED TOTAL OFFGAS HOLDUP SYSTEM DELAY TIME, AND THE KNOWN FRACTION OF THE OFFGAS STREAM RELEASED VIA THE GLAND EXHAUSTER.

2. AN ISOTOPIC ANALYSIS FOR NOBLE GASES IS NORMALLY NOT POSSIBLE AT THE BUI(DING VENTS.

THEREFORE, FOR VENT RELEASES, THE ISOTOPIC MIXTURE IS ASSUMED TO BE EQUAL TO THE MIXTURE DETERMINED AT THE SJAE.

3.

TOTAL RELEASES REPORTED IN TABLES 1A AND 2A 00 NOT INCLUDE NUCLIDES WHICH WERE BELOW MINIMUM DETECTABLE ACTIVITY (MDA).

HDA VALUES ARE INCLUDED IN TABLES IB, IC, AND 28.

COMPARISONS OF RELEASES TO APPLICABLE LIMITS DO

.NOT INCLUDE NUCLIDES WHICH WERE BELOW MDA.

MAXINUM ALLOWED

( 3A VALUES ARE ESTABLISHED IN THE TECHNICAL SPECIFICATIONS.

4.

INFORMATION SPECIFIED IN REGULATORY GUIDE 1.21 WHICH IS NOT APPLICABLE TO THE MONTICELLO PLANT IS INDICATED BY

'NA'.
