8.0 Data Interpretation and Conclusions Interpretations and conclusions regarding all types of samples analyzed during 1985 are discussed in the following sections. Assessment of pre-operational and operational data revealed no significant changes to environmental radiation levels. There was no observed impact on the environment due to PVNGS operations. For the calculation of means, a value of one half the detection limit is used for all samples with activities below the de'tection limit.

8.1 Air Particulates Air particulate samples were collected from each of the twelve monitoring sites on a weekly basis during 1985.

Air filters were analyzed for gross alpha and gross beta activities. Gamma Spectral analysis of the air filters was done on the individual filters for Stations 14A, ISA,17A, 21A, 29A and 40A due to the Salt Drift Monitoring Program.

Gamma Spectral analysis for the other stations was performed on quarterly composites by station.

Ten air particulate samples were marked as possibly invalid upon arrival at CEP.

The samples and the reason for the questionable statuses are listed below:

Second Quarter 1985 Date Co!!ected Site # Reason 05/29/85 17A Malfunction of pressure relief valve Third Quarter 1985 Date Collected Site # Reason 07/31/85 6A Power interupted during sampling period 03/07/35 4A Flow calibration failed 03/07/85 6A Flow calibration and redline criteria not available 09/18/85 29A Numerous insects on air particulate filter 10/02/35 4A Heavy dirt on air particulate filter

'l Fourth Quarter 1985 Date Collected Site # Reason 10/09/85 29A Insects on particulate filter 10/16/85 15A Malfunctioning sampler 10/23/85 15A Malfunctioning sampler 12/11/85 4A Wet air particulate filter Table VII presents second quarter Gross Beta results. Station 6A showed the highest activity during the quarter (0.0410.002 1 pC1/m3 collected 06/19/85-06/26/85). The Station IA sample collected 05/29/85-06/05/85 showed the lowest level at 0.0151 0.002 pCi/m3. Weekly mean activities ranged from a low of 0.01810.002 pC1/m3 during the period of 05/29/85-06/05/85 to a high of 0.03210.003 pCi/m3 in the week of 06/26/85-07/03/85. The range of results are comparable to previous quarterly data and do not indicate any anomalies.

Table VIII presents the Gross Beta levels during the third quarter of 1985. A maximum value of 0.03610.002 pCi/m3 was observed at Stations 35A and 44A I (collected 07/03/85-07/10/85). The lowest level of activity was 0.01010.002 pCi/m3 at Station 44A during the collection period of 07/24/85-07/31/85.

Weekly mean activities ranged from a minimum of 0.0181 0.002 pCi/m3 (07/17/85-07/24/85), to a maximum of 0.0321 0.003 pCi/m3 in the period of 07/03/85-07/10/85. The range of results are comparable to previous quarterly data and do not indicate any anomalies.

Table IX presents the Gross Beta activities seen in the fourth quarter. Observed levels varied from 0.0081 0.006 pCi/m3 at Station 14A (co!!ected 12/26/85-01/02/86), to 0.05710.002 pCi/m3 at Station 6A (coilected 12/26/85-01/02/86).

Weekly mean activities ranged from 0.01310.002 pCi/m3 during the collection period of 11/27/85-12/04/85 to 0.03710.003 pCi/m3 collected 10/23/85-10/30/85 and 0.0371 0.005 pCi/g collected 12/13/85-12/26/35. Based on data from other nuclear reactor environmental monitoring programs, the trend for Gross Beta in air particulates for the PVNGS during the fourth quarter of 1935 is similar to those for other reactor sites located west of the Mississippi River.

Table X contains the mean Gross Beta activities by station. Mean quarterly and mean annual activities are calculated using all weekly activities except those marked invalid. Mean activities fo each quarter ranged from a low of 0.0231 0.006 at Station 21 A during the third quarter, to a high of 0.03310.010 pCi/m3 at Station 15A in the fourth quarter. Annual mean activities compare very well and fall between 0.02610.006 pCi/m3 (Stations 17A, 21 A and 35A) and 0.0291 0.007 pCi/m3 (Station 15A). Mean activities seen during 1985 are consistent with past results.

The average gross beta activity for each quarter is as follows:

pCi/m3 l Second Quarter 1935 0.027 1 0005 Third Quarter 1935 0.024 3 004 0

Fourth Quarter 1935 0.030 1 0009 l

8.2 Airborne Radioiodine Samples for airborne radioicdine monitoring are collected concurrently with the air particulate samples. These samples are collected in charcoal cartridges and analyzed for I-131.

I As can be seen in Table XIV no radiciodine samples co!!ected during the second quarter of 1935 shewed observable I-131 activity.

Third quarter radioicdine data may be found in Table XV. No samples indicated I-131 activity above the detection limit of 0.007 pCi/m3.

As can be seen in Table XVI no radiciodine samples collected during the fourth quarter of 1985 showed observable I-131 acitivty.

8.3 Thermoluminescent Dosimetry Thermoluminescent dosimeters were placed in fifty locations ranging from one to forty-five miles from the Palo Verde Nuclear Generating Station. Beginning in 1984 the Panasonic Model 812 Dosimeter replaced all other TLD's in use. The 312 is a multi-element dosimeter combining 2 elements of Lithium Borate and 2 Calcium Sulfate elements.

Tables XVII to XIX present the results of the Quarterly exposures for 1985.

Quarterly data obtained from TLD's are graphically presented in Figures 16 to 18.

Differences in individual station mean values represent statistical variation more so than actual fluctuations in the background radiation around the Palo Verde Nuclear Generating Station and tend to vary about an approximate mean of 24 mrem / quarter. Operational data for 1985 compare very closely with pre-operational data.

I Figure 19 illustrates the mean TLD activity from 1981 through 1985. These values were obtained by averaging all TLD's in the field during the cuarter. (TFe control TLD was not included). Figure 19 illustrates the me.o are with high and low standard deviations of the mean for each quarter.
