Niagara Mohawk Power Corporation TECHNICALSPECIFICATION LIMITS A)
FISSION AND ACTIVATIONGASES 1.
The dose rate limitof noble gases from the site to areas at and beyond the site boundary shall be less than or equal to 500 mrems/year to the total body and less than or equal to 3000 mrems/year to the skin.
2.
The air dose due to noble gases released in gaseous effluents from the Nine Mile Point 1 Station to areas at and beyond the site boundary shall be limited during any calendar quarter to less than or equal to 5 milliroentgen for gamma radiation and less than or equal to 10 mrads for beta radiation, and during any calendar year to less than or equal to 10 milliroentgen for gamma radiation and less than or equal to 20 mrads for beta radiation.
B&C) TRITIUM,IODINES AND PARTICULATES, HALFLIVES ) 8 DAYS 1.
The dose rate limitof Iodine-131, Iodine-133, Tritium and all radionuclides in particulate form with half-lives greater than eight days, released to the environs as part of the gaseous wastes from the site, shall be less than or equal to 1500 mrems/year to any organ.
2.
The dose to a member of the public from Iodine-131, Iodine-133, Tritium and all radionuclides in particulate form with half lives greater than eight days as part of gaseous effluents released from the Nine Mile Point 1 Station to areas at and beyond the site boundary shall be limited during any calendar quarter to less than or equal to 7.5 mrems to any organ and, during any calendar year to less than or equal to 15 mrems to any organ.
D)
LIQUIDEFFLUENTS 1.
The concentration of radioactive material released in liquid effluents to unrestricted areas shall be limited to the concentrations specified in 10 CFR Part 20, Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained noble gases.
For dissolved or entrained noble gas, the concentration shall be limited to 2E-04 microcuries/ml total activity.
2.
The dose or dose commitment to a member of the public from radioactive materials in liquid effluents released from Nine Mile Point Unit 1 to unrestricted areas shall be limited during any calendar quarter to less than or equal to 1.5 mrems to the total body and to less than or equal to 5 mrems to any organ, and during any calendar year to less than or equal to 3 mrems to the total body and to less than or equal to 10 mrems to any organ.
Page 2 of2 MEASUREMENTS AND APPROXIMATIONSOF TOTALRADIOACTIVITY Described below are the methods used to measure or approximate the total radioactivity and radionuclide composition in effluents.
A)
FISSION AND ACTIVATIONGASES Noble gas effluent activity is determined by on-line gamma spectroscopic monitoring (intrinsic germanium crystal) or gross activity monitoring (calibrated against gamma isotopic analysis of a 4.0L Marinelli grab sample) of an isokinetic stack sample stream.
B)
IODINES Iodine effluent activity is determined by gamma spectroscopic analysis (at least weekly) of charcoal cartridges sampled from an isokinetic stack sample stream.
C)
PARTICULATES Activityreleased from main stack is determined by gamma spectroscopic analysis (at least weekly) of particulate filters sampled from an isokinetic sample stream.
For emergency condenser vent releases, effluent curie quantities are estimated based on the isotopic distribution in the Condensate Storage Tank and the Emergency Condenser shell.
Actual isotopic concentrations are found via gamma spectroscopy.
Initial release rates of Sr-89, Sr-90 and Fe-55 are estimated by applying scaling factors to release rates of gamma emitters.
For emergency condenser vent
- releases, the activity ofTritium released during normal operation or during batch releases is conservatively estimated by multiplying recent condensate storage tank H-3 activity by assumed steaming rates out the vents.
D)
TRITIUM Tritium effluent activity is estimated by liquid scintillation or gas proportional counting of monthly samples taken with an air sparging/water trap apparatus.
E)
LIQUIDEFFLUENTS Isotopic analysis of a representative sample of each batch and composite analysis of non-gamma emitters.
F)
SOLID EFFLUENTS Isotopic contents of waste shipments are determined by gamma spectroscopy, gross alpha and water content analyses of a representative sample of each batch.
Scaling factors established from primary composite sample analyses conducted off-site are applied, where appropriate, to find estimated concentration of non-gamma emitters.
For low activity trash shipments, curie content is estimated by dose rate measurement and application of appropriate scaling factors.

SUMMARY
OF CHANGES TO THE OFFeSITE DOSE CALCULATIONMANUAL There was one revision to the Unit 1 ODCM during the reporting period.
Copies of revisions 13 and 14 are attached and below ls a summary of changes presented to and approved by the Station Operations Review Committee in June 1994. The summary also includes a justification for each change.
Chan e Summa 11 ~P69 - An editorial change is mode to locations 4134 on Figure 61-2 (memo from Bg. Zncharek to gD. Thomas, dated January 6, 1994).
The map revision lFigure 5.1-2) corrects an air sampling and an environmental TLD location which were not properly transferred during conversion to CAD. Calculations or deposition (D/0) parameters are not impacted.'1~F16-A change to section 3 2, 'Doss snd Dose Rote Determlnntlons's mode to ctsrify that for ground lovel releases from the Emergency Condenser Vent, without tube leakage, a condensate storage tank and emergency condenser shell isotopic distribution is to be used.
This clarification improves the accuracy of dose calculations by applying correct isotopic distributions to the evaluation.
No changes are made to the calculational methodology, with the exception of which isotopic distribution to apply. Without this clarification, an overly conservative off-gas isotopic distribution would have been applied lReference, NRC Assessment of ODCM, April 1994).

These totals were reported separately from "10CFR61 Solid Waste Shipped for Burial" since (a) waste classification and burial was performed by the vendors, and (b) Technical Specification 6.9.1 requires reporting of "information for each class of solid waste (as defined by 10CFR61) shipped off-site during the reporting period". The information provided in this section, therefore, is in addition to that required by the Technical Specifications.
The following data represents the actual shipments made from the off-site vendors of our non-compacted commingled trash that was processed prior to burial.
