PACIFIC GAS AND ELECTRIC COMPANY DOCKET NO. 50-133 LICENSE NO. DPR-7 RADI0 ACTIVE EFFLUENT RELEASES AND WASTE DISPOSAL FROM HUMBOLDT BAY POWER PLANT UNIT NO. 3, COVERING THE PERIOD JULY 1, 1986 THROUGH DECEMBER 31, 1986 This report summarizes the quantity of each of the principal radiunuclides released in liquids and gaseous effluents to unrestricted areas and summarizes radioactive waste disposal from July 1, 1986 through December 31, 1986. 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 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> decay period" is 0.18 micro-Curies per second.
d. Liquid Effluents: 10CFR20.
2. Maximum Permissible Concentrations:

The concentrations used to determine allowable release rates or concentrations are as follows:

Gaseous effluents:

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, Liquid effluents:
a. 10CFR20, Table II, Appendix B. Refer to Table C1 for the values used, based on the mixturas for each quarter.

DCPP2 1 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 determine 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: Due to the long decay time since operation (shutdown July 2, 1976) no detectable releases of radioactive iodines of plant origin can be expected. Since the license no longer requires that these radionuclides be monitored, these radionuclides are not reported.
c. Particulates: Filter papers are removed from the stack sampling system weekly and, after 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> decay, are analyzed for gross alpha (Internal Proportional Counter) and the concentration of gamma 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 particulate 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 sarrples vere gamma spectrum counted and counted for gross beta radioactivity. All statistically important peaks were identified. Quarterly composites of all batches were anal Tritium and radioactive Strontium (yzed for gross alpha, 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: 44 (A total of 16,089 gallons of laundry waste and 128,280 gallons of treated waste tank discharge).

DCPP2 2

2) Total time period for batch releases: 7.40E3 minutes.
3) Average time period for a batch release: 1.68E2 minutes.
4) Maximum time period for a batch release: 4.77E2 minutes.
5) Minimum time period for a batch release: 5.00E0 minutes.
6) Average stream flow during periods of release of effluents into a flowin Not applicable (Discharge is into 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. GASEOUS 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 summarizes 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 summarizes the total quantity for each of the nuclides determined to be released.

D. SOLID WASTE During the report period, a total of 148.8 cubic meters of solid radioactive waste, totaling 14.5 Curies, was shipped. Table D-1 summarizes these radioactive waste shipments.

E. RADIOLOGICAL IMPACT 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 radiatinn and to the consumption of aquatic foods. Other pathways contribute less than 5% of the total doses to the public. Maximum doses to indivirtuals are summarized in Table El. 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 0.011 mrem per Yr (Total Dody) for the Adult age group, and 0.016 mrem per Yr for the bone of the Child 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 Yr.

3. Total body doses to the average individual in unrestricted areas 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 tests (ya significant differences two-way 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 e::posure results for each station were based on biweekly data extrapolated to 26 weeks and are listed in order from highest to lowest exposures.

F. METEOROLOGICAL DATA The meteorological data logging system was removed from service in 1967.

Therefore, the information specified by Regulatory Guide 1.21, Appendix B, Section F, is not readily available for this report period.

Table F1 summarizes the cumulative joint frequency distribution of wind speed, direction, and atmospheric stability for the period April,1962 through June, 1967 when the meteorological data logging system was in service.
