'I 4 NINE MILE POINT NUCLEAR STATION-UNIT 1 SEMI-ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY-JUNE 1992 SUPPLEMENTAL INFORMATION Facility: Nine Mile Point Unit¹1 1.Technical Specification Limits: Licensee: Niagara Mohawk Power Corporation A)Fission and Activation Gases: 1~The dose rate limit of 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.

BRC)Tritium, lodines and Particulates, half lives>8 days: 1.Tahe dose rate limit of 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)Liquid Effluents:

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.002757LL I

D.Liquid Effluents (Cont'd): 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 rnrems 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 mrerns to any organ.2.Measurements and Approximations of Total Radioactivity:

Described below are the methods used to measure or approximate the total radioactivity and radionuclide composition in effluents.

A)Fission and Activation Gases: 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)lodines: Iodine effluent activity is determined by gamma spectroscopic analysis (at least weekly)of charcoal cartridges sampled from an isokinetic stack sample stream.C)Particulates:

Activity released 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 batch releases, effluent curie quantities are estimated by subtracting activity remaining in the shell side of the emergency condenser after batch release from activity delivered to the shell from Make-Up sources.Actual isotopic concentrations are found via gamma spectroscopy.

Batch release activities of Sr-89, Sr-90 and Fe-55 are estimated by applying scaling factors to activity concentrations of gamma emitters.The activity of tritium 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)Liquid Effluents:

Isotopic analysis of a representative sample of each batch and composite analysis of non-gamma emitters.002767LL

~Measurements and Approximations of Total Radioactivity (Cont'd): 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.002757LL (4)

SUMMARY

OF CHANGES TO THE OFFNITE DOSE CALCULATION MANUAL The Unit 1 ODCM Revision 9 was implemented in June 1992.Copies of Revisions 8 and 9 are attached.The following sampling locations have been changed or added to the environmental monitoring program as a result of a change from the land use census, except locations¹30 and 52, which were typographical errors.The land use census showed potential alternate sample locations that could be used since garden locations can change significantly from year to year.The locations include numbers 59, 61 and 63.In addition, milk sample location numbers 64, 65 and 66 were added to show potential locations that have been used in the past and that are also currently used.These locations are not Technical Specification locations.

SUMMARY

OF INOPERABLE MONITORS Monitor Dates of Inoperability Cause and Corrective Actions RAGEMS Entire Reporting Period The Radioactive Gaseous Effluent Monitoring System (RAGEMS)modifications have been completed and successfully tested.The pre-operational test was executed and signed on June 5, 1992 and SORC approved on June 16, 1992.No test exceptions were taken and all acceptance criteria were met.Efforts to complete the testing by March 31, 1992 as committed, were delayed by the forced outages.All items identified in previous reports have been addressed and are proven by manual, automatic and semi-automatic operation.

In addition, the operational system has many software program user enhancements and troubleshooting aids.Radiation detector rebuilds and calibrations and chemistry personnel training is in progress.RAGEMS is intended to be used as an emergency stack gas monitoring system.002757LL a l'
