t Pag 2 1 of 6 Oconee Nuclear Station Annual Radiological Environmental Monitoring Program Operating Report for 1984
- Exhibit I summarizes the results of the Environmental-Radiological Monitoring Program for 1984.
Duke Power Company's Environmental Radiological Laboratory (ERL) performs the program analyses with the exception of H-3 analyses which are performed by Teledyne Isotopes. Both the ERL and Teledyne Isotopes participate in the EPA Cross-Check Program; the cross-check code designations are CP and CJ respectively.
Some unavoidable deviations-from-the~ required analysis schedule occurred during the year. These deviations are tabulated below.
- Unavailable Analyses Sample (Location #), Date Reason A. Air Filter / Cartridge
- 1. (061), (074), 3/27-4/03/84 Sampler was not operating at time of sample collection. ERL was unable to calculate sample volume.
B. Air Filter
- 1. (061), 4/03-4/10/84 Sampler had stopped prior to sample collection. Due to unavailability of stop flow rate total volume could not be calculated.
- 2. (061),.(074), 4/17-4/24/84 Samples were packed in cooler l
containing milk sample packed in ice j and the filters were saturated with water'upon receipt at the ERL.
- C. Air Cartridge
- 1. (061), 4/03-4/10/84 Sampler had stopped prior to sample collection. Due to unavailability of stop flow rate total volume could not be calculated.
- 2. (061), (074), 4/17-4/24/84 Samples were packed in cooler containing milk samples packed in ice and the cartridges were saturated with water upon receipt at the ERL.
- 3. (073), 4/08-5/15/84 Sampler running but no air flow at time of collection.
k-
r Phg2 2 cf 6 D. Milk
- 1. (071), 10/09/84 Sample backlog delayed analysis until 11/09/84. A power failure the evening of 11/09/84 caused counts to be lost.
Repeat analysis would have delayed other analyses. jeopardizing several more LLD's for other samples.
"E. Broadleaf Vegetation
- 1. (028), 10/09/84 The routine Tech Spec samples were (073) stored with 17 special broadleaf samples collected by Oconee on 9/28/84 and were inadvertently discarded with the special samples prior to analysis.
F. TLD
- 1. (024) (051), 1/01-3/31/84 Missing (054) (056)
- 2. (024) (042), 4/01-6/30/84 Missing (054) (056)
- 3. (046) (048), 7/01-9/30/84 Missing (054)
Deviations from Required Sampling Schedule Sample (Location #), Date Reason A. Milk
- 1. (066), 2/28/84 Require sample volume not available.
Collected about 1500 ml instead of the required 3500 ml.
B. Air Filter / Cartridge
- 1. (060), 1/10/84 - 1/17/84 Sampler turned off on 1/12/84 from 1400 to 1405 hrs. for maintenance on sampler housing.
- 2. (072), 3/13/84 - 3/20/84 Sampler had no flow when sample collected. Sample collection period 168.9 hrs.
- 3. (072), 3/20/84 - 3/27/84 Sampler had to be replaced during sampling period on 3/20/84 from 0928 to 1145 hrs, r

Quarterly composite affected as it is not representative of entire collection period.
To reduce the number.of sample deviations due to equipment failure, all composite water samplers and cartridge air samplers were replaced in 1984.
Also, air sampling filters and cartridges are now bagged and sealed to prevent them from becoming wet during transport to the Environmental Radiological
-Laboratory.
Lower Limits of Detection Not Met Sample (Location #), Date Radionuclide Reason A. Drinking Water Comp. -
- 1. (066), 2/07-2/28/84 BaLa-140 LLD not met due to background contributions from other radionuclides in sample.
B. Milk
- 1. (066), 2/28/84 Cs-134 LLD not met for Cs-134 because of bad computer memory board.
Pega 5 cf 6 p
(069), 9/25/84
~
- 4. 3. I-131 Large sample backlog caused too much decay time between sample collection and ccunt date.
To lessen the incidence of missed LLD's due to sample backlog, the ERL purchased two (2) additional Alpha / Beta Counters in 1984.
On January 1, 1984 the location for sampling fish in ONS liquid effluent pathway changed from location number 013 (7 miles downstream) to number 063, a few ~xundred yards downstream of the effluent release point. Catfish collected at 063 in May of 1984 indicated Cs-137 and Cs-134 concentrations higher than had been typical for old location number 013. The System Health Physicist requested that the station collect fish from old location 013 as well as location 063 for a two year period to determine how much of the increase in radiocesium concentration observed at the new location could be due to proximity to the nuclear station. In June and December 1984, the NRC was notified that reporting levels in Table 4.11-3 of the Radiological Effluent Technical Specifications had been exceeded.
Page 10 of Exhibit 1 contains a summary of the regular Tech Spec samples plus additional samples collected at locations 013 and 063.
Fish samples collected during 1984 showed a significant increase in radiocesium activity over 1983 samples. This increase can be attributed to the change in sampling locations mentioned above since the old location (013) is not showing an increase of radiocesium levels in 1984 over 1984.
Based on recommendations from Analytics, Inc. and guidance from the system health physics group, the ERL modified the counting technique for air particulates beginning second quarter 1984. Subsequent to April 3, 1984 all air filter and cartridge samples were counted separately instead of being counted as a composite as had been previously practiced. Pages 1-3 of Exhibit I contain composite results for the period January 1, 1984 - April 3, 1984 and separate filter and cartridge results for the period April 3, 1984 - December 31, 1984.
Comparison of Environmental and Liquid Waste Release Data The annual summary sheets (Exhibit 1) identify fish (Cs-134, Cs-137) and
, drinking water (H-3) as the two pathways having significant activity in the environment.
Dose calculations were performed per Reg. Guide 1.109 using the Exhibit I data for Cs-134 and Cs-137. The results of these calculations show a liver dose of 3.7 mres/yr for teens and adults. The same calculations were also done using Liquid Waste Release data for 1984 with a result of 0.37 arem/yr. The reason for the difference between these two doses is demonstrated by Exhibit 2 which m
Peg; 6 of 6 shows release of radiocesium by year and also by accumulation over the operating life of the station. This graph shows that the majority of radiocesium released by Oconee was released prior to 1978. This suggests that much of the ac~tivity found in fish may be due to old radiocesium released prior
.to 1984. The calculation based on liquid releases does not take account of old releases. .
Calculations performed for H-3 activity in drinking water show a dose of 0.077 ares /yr for both actual environmental data and Liquid Waste Release data. -
