O Report 420-86.186 INTRODUCTION O

This annual report contains the results from the environmental radiation monitoring program for the Humtoldt Bay Power Plant (HBPP) Unit 3 compiled for calendar year 1985. Samples collected for the monitoring O

program were in accordance with the requirements of the North Coast Water Quality Control Board '2 and the California State Department of I

Health.

The types of samples collected include 48 marine (i.e., fish, O

algae, bottom sediment),19 terrestrial (i.e., milk, water, soil),103 air particulate filters, and environmental dosimeters (777 stray radiation ion chamber results, 358 film packs, and 204 TLD results). The analyses include O

gross beta, gama isotopic, iodine (I-131), and potassium (K and K-40) determinations, which are perfonned at the Pacific Gas and Electric Company, Department of Engineering Research (DER). Environmental dosimetry is

'O performed by HBPP personnel (stray radiation ion chamber readings), by DER personnel (TLD processing), and by an outside contractor (film pack processing).

v As part of the quality control measures for the monitoring program, DER participates in the Environmental Protection Agency (EPA) Intercom-parison Studies Program and an intercomparison program with the State of

'O California. The results from these programs are shown in the tables and the appendix. Also included in the report are the data from the radiochemical analyses of influent and effluent water for HBPP Unit 3.

O METHODS OF SAMPLE COLLECTION AND ANALYSIS Air particulate, milk, water, and soil samples are collected and the

=O stray radiation chambers are read by PGandE Nuclear Plant Operations personnel at HBPP. Marine samples (including algae, fish and invertebrates, and sediment) are collected by personnel from Humboldt State University

O

P 2

Report 420-86.186 Foundation under the direction of Dr. J. A. Gast. Figures 1 and 2b show the locations where these samples are collected (except dosimeter locations).

Air samples are collected at two locations (Station 3 and 45) on a o

weekly basis. The constant flow samplers maintain a flow rate of 1-1.5 cubic feet (28-42 liters) per minute; an H-70 type filter paper is used as the sampling medium. The filters are counted on a gas flow propor-tional counter to determine gross beta activity at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after collection to allow naturally occuring short-lived radionuclides to decay.

Milk samples are collected from two local dairies (Stations 16 and 48) on a quarterly basis. The samples are analyzed by gamma isotopic e

spectroscopy, then an aliquot is taken to be freeze-dried for gross beta analysis, and then radioiodine analysis is performed on the remaining sample. To prepare the sample for radiciodine analysis, stable iodine is added to the raw milk to determine chemical recovery.

Iodine is then separated from the milk by an ion exchange resin; the iodine is then stripped from the resin, purified, and precipitated as cuprous iodide for measurement by beta-gama coincidence spectrometry. The typical detection limit using this method is 0.2 pCi/ liter for I-131.

Domestic water is collected on a quarterly basis. The sample is analyzed by gama spectroscopy, then an aliquot is taken for tritium (H-3) analysis. Also an aliquot is evaporated to dryness for gross beta activity determination. The aliquot for tritium analysis is distilled and then a scintillation cocktail is added to the distillate before counting in a liquid scintillation spectrometer. The limit of detection by this method is typically 0.5 pCi/ milliliter for H-3 in water.

Soil samples are collected from two locations (Stations 1 and 5) on a quarterly basis. These samples are analyzed for gross beta activity and

.O by gamma isotopic spectroscopy.

Marine sanples include algae, fish and invertebrates, and sediment from five locations in Humboldt Bay. The algae, fish, and invertebrate

'O samples are analyzed for gama isotopes, then freeze-dried and analyzed for gross beta activity.

Sediment is oven-dried and then analyzed for gross beta and gama activity.

O Environmental radiation dosimetry (gama radiation exposure) is determined by stray radiation ion chambers (Victoreen, Model 239), and film packs for off-site locations (as shown in Figure 2a). Thermoluminescent O

dosimeters (Panasonic Model UD 814) are used to monitor the on-site locations (as shown in Figure 4). The stray radiation ion chambers are read in the field on a biweekly basis; the film packs are exchanged on a O

monthly basis. These film packs are supplied and read out by the Radiation Detection Company (RDC) of Sunnyvale, California; the results are reported relative to the background exposure at the RDC laboratory (8 mR/ month).

(O The TLDs are exchanged on a monthly basis and are processed at the DER

(

laboratory.

O The sample is analyzed by gama spectroscopy, then an aliquot is taken for tritium (H-3) analyses. The tritium sample is prepared in the same manner as the domestic water samples.

,0 contribution to the gross activities. By applying the factor of 830 pCi K-40 per gram of natural potassium to the measured potassium concentration,

.'O the activity of K-40 in a sample is calculated.

The gama spectroscopy is done using either a Ge(Li) or Intrinsic I

Germanium detector and a multichannel pulse height analyzer. The limit of

-O detectability attained in the gamma scan is typically 5 pCi/1 of water solution containing a single radionuclide.

The gross-beta analyses are performed on a low background, thin

O window proportional counter with a typical limit of detectability of l

0.5 pCi/gm of a K-40 standard.

The + term in the following tables is the two-sigma error (i.e., the

O 95 percent confidence level). The lower limit of detection (LLD) is defined as the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be lC detected with a 95 percent probability with only 5 percent probability of falsely concluding that a blank observation represents a "real" signal.

V, Y, and t are used in the calculation.

It should be recognized that the LLD is defined as an a_ priori (before the fact) limit representing the capability of a measurement system and not i

as an a posteriori (after the fact) limit for a particular measurement.

Analyses are performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally background fluctuations small sample sized, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. Table A-5 lists the maximum values for the LLDs of the analyses performed for the HBPP Environmental Monitoring Program.

DISCUSSION OF ANALYTICAL RESULTS The environmental samples analyzed for this report contained radioactivity levels comparable to preoperational levels of similar samples.4 The maximum integrated gamma radiation exposure at an off-site location was 96 mR at Station 27.

An on-site TLD monitoring program was started July 1983; data for 1985 is shown in Table A-4c.

The highest integrated gamma radiation exposures at on-site locations for 1985 were along the northern site boundary near the Waste Handling Area. This is due to the increase in processing radioactive waste for disposal in the Waste Handling Area.

Figure 3 graphically presents data for 3 stations over a 5-year span. Air particulate gross beta activity at Station 3 (nearest air O

sampling station to HBPP) is displayed as well as a comparison between gama radiation exposure at Station 14 (nearest occupied public facility) and Station 2 (a background location in Fortuna).

O EPA LABORATORY INTERCOMPARISON PROGRAM The DER radioanalytical laboratory participated in the EPA Environmental Radioactivity Laboratory Intercomparison Studies O

(Cross-Check)Programduring1984. Participation included the following determinations (sample medium-radionuclide combination): milk containing gama emitters; water containing tritium, gama emitters, and gross beta O

activity; and air particulate filters containing Cs-137 and gross beta activity. The DER laboratory performed three independent analyses of each sample; the EPA calculates an average and compares the results with the O

known value (as determined by EPA analyses) and the grand average of all participating laboratories. Table B-2 is a sumary of these results and comparisons. The DER results are within the acceptable range as O

established by the EPA.
