DPR-7 RADI0 ACTIVE EFFLUENT RELEASES AND WASTE DISPOSAL FROM HUMBOLDT BAY POWER PLANT UNIT NO. 3, COVERING THE PERIOD JULY 1, 1985 THROUGH DECEMBER 31, 1985 This report sumarizes the quantity of each of the principal radionuclides released in liquids and gaseous effluents to unrestricted areas and summarizes radioactive waste disposal from July 1,1985 through December 31, 1985. This report is required by Section IX.I.3.a of the Humboldt Bay Power Plant, Unit No. 3 Technical Specifications.
A. SUPPLEMENTAL INFORMATION
: 1. Regulatory Limits:
: a. Fission and activation gases: The current license limits are 50,000 micro-Curies per second for an annual average release rate and 500,000 micro-Curies per second for an instantaneous release.
: b. Iodines: Refertoc.(Particulates).
  -                c. Particulates: The current license limit "for halogens and particulate material based on the isotopes present on the sample filters after 48 hours decay period" is 0.18 micro-Curies per second.
: d. Liquid Effluents:      10CFR20.
: 2. Maximuin Permissible Concentrations:
The concentrations used to determine allowable release rates or concentrations are as follows:
: a. Fission and activation gases: Not applicable,
: b. Iodines: 3E-10 micro-Curies per cc.
: c. Particulates (half-lives >8 days): 3E-10 micro-Curies per cc,
: d. Liquid effluents:     10CFR20. Table II, Appendix B. Refer to Table C1 for the values used, based on the mixtures for each quarter.
DCPP2 1
: 3. Average energy:
Not applicable.
: 4. Measurements and Approximations of Total Radioactivity:
The methods used to measure or approximate the total radioactivity in effluents and to detennine radionuclide composition are as follows:
: a. Fission and activation gases: Due to the long decay time since operation (shutdown July 2,1976) no detectable releases of fission and activation gases can be expected. Accordingly, these radionuclides are not reported,
: b. Iodines: Charcoal cartridges are removed from the stack sampling system weekly and, after 48 hour decay, are analyzed for I-131 and 1-133 (Intrinsic Gennanium detector). Due to the long decay time since operation (shutdown July 2,1976) no detectable releases of radioactive iodines can be expected.
Accordingly, these radionuclides are not reported.
: c. Particulates:            Filter papers are removed from the stack sampling system weekly and, after 48 hours deca for gross alpha (Internal Proportional Counter)y,                                        and the  are analyzed concentration of gama emitting nuclides (Intrinsic Germanium detector). All statistically significant peaks are identifed.
The filters for each quarter are analyzed for radioactive Strontium (all Sr-90 due to decay time).
The error of the reported release values is estimated based on uncertainty in sample flow rate, stack flow rate, detector calibration, and typical sample counting statistics,
: d. Liquid effluents: Liquid waste batch samples were gama spectrum counted and counted for gross beta radioactivity. All statistically important peaks were identified. Quarterly composites of all batches were analyzed for gross alpha.
Tritium and radioactive Strontium (Sr-90).
The error of the reported release values is estimated based on uncertainty in sample volume, batch volume, detector calibration, and typical sample counting statistics.
: 5. Batch releases:
: a. Liquid:
: 1)    Number of batch releases: 71 (A total of 14,518 gallons of laundry waste and 259,858 gallons of treated waste tank discharge).
DCPP2 2
: 2)   Total time period for batch releases:  1.20E4 minutes.
: 3)   Average time period for a batch release:  1.69E2 minutes.
: 4)   Maximum time period for a batch release: 4.75E2 minutes.
: 5)   Minimum time period for a batch release:  1.00E1 minutes.
: 6)   Average stream flow during periods of release of effluents into a flowin            Notapplicable(Dischargeisinto HumboldtBay)gstream:
: b. Gaseous: None.
: 6. Abnormal releases:
: a. Liquid:
: 1)   Number of releases: None.
: 2)   Total activity released: None,
: b. Gaseous:
: 1)  Number of releases: None.
: 2)  Total activity released: None.
B. CASE 005 EFFLUENTS The monitoring systems associated with the liquid radwaste system vent to
  -         atmosphere indicated that no detectable releases of radioactive gases occurred during the report period. Because quarterly checks of the HEPA filters on the vent were satisfactory, only gaseous radioactive waste releases made via the 250 foot stack are reported.
Table B-1 sumarizes the total quantities of radioactive effluents released by quarter. Table B-2 summarizes the total quantities for each of the nuclides determined to be released.
C. LIQUID EFFLUENTS Analysis of weekly composite samples from the plant intake and the plant effluent canal and monitoring by the liquid radwaste discharge monitor confirmed that no unaccounted release of radioactive waste occurred during the report period.
Table C-1 summarizes the total quantities of radioactive liquid effluents released by quarter. Table C-2 sumarizes the total quantity for each of the nuclides determined to be released.

  .       D. SOLIO WASTE During the report period, a total of 687.6 cubic meters of solid radioactive waste, totaling 181.8 Curies, was shipped. Table 0-1 summarizes these radioactive waste shipments.
E. RADIOLOGICAL liPACT ON MAN Plant releases continued to be much lower than when the plant last operated. A comparison of calculated doses by various paths has shown that the off-site doses are primarily due to direct radiation and to the consumption of aquatic foods. Other pathways contribute less than 5% of the total doses to the public. Maximum doses to individuals are sunenarized in Table E1. These doses comply with 40CFR190 since there are no other fuel cycle facilities within 8 km.
: 1. Doses to the average individual in the population from all receiving-water-related pathways were calculated for the releases detected, based on the guidance of Regulatory Guide 1.109. The maximum results were 0.023 mrem per Yr (Total Body) for the AJult age group, and 0.033 mrem per Yr for the liver of the Teen age group.
: 2. Total body doses to the average individual in the population from gaseous effluents to a distance of 50 miles from the site were calculated on a comparative basis and found to be insignificant.
The highest potential calculated dose is less than 0.005 mrem per Y r.
: 3. Total body doses to the average individual in unrestricted creas from direct radiation from the facility have been measured with 30 dosimeter stations (Figure 1) in the vicinity of the Plant.
Ionization chambers, read on a biweekly basis, are used for dosimetry. Stations 2 and 5 are considered to be background in that they are assumed to be completely removed from the influence of the plant. In order to test for statisticall between stations, two statistical testsa (y     significant two-way       differences classification, and a 95% confidence limit least significant difference test) were made for the dosimeter station readings. The following table summarizes the results of this analysis. The report period exposure results for each station were based on biweekly data extrapolated to 26 weeks and are listed in order from highest to lowest exposures.

Maximum total body and organ doses to individuals in unrestricted areas from receiving-water-related exposure pathways has been calculated for detected liquid releases, based on the average concentrations for the report period, and the generic parameters of Regulatory Guide 1.109,
: 2. Total body and skin doses to individuals exposed at the point of maximum off-site ground-level concentrations of radioactive materials in gaseous effluents was not calculated because there were no significant releases of radioactive noble gases.
: 3. Organ doses to individuals in unrestricted areas from radioactive Iodine and radioactive Particulates for all pathways of exposure was calculated on a comparative basis and found to be insignificant.
The highest potential calculated dose to any organ of an individual is less than 0.005 mrem /Yr.
: 4. Total body doses (to the maximum individual in the population) are based on TLD results of stations at the site boundary, using the shore-line occupancy factors given in Regulatory Guide 1.109 for the maximum potential individual (Teen age group).
