Measurements and Approximations of Total Radioactivity 1,

Gaseous Effluent a.

Fission and Activation Gases Periodic grab samples are obtained from the Main Plant Exhaust Duct, Fuel Building Exhaust Vent and Radwaste Building Exhaust Vent. These samples are analyzed utilizing high purity germanium detectors coupled to computerized pulse height analyzers. The sampling and analysis frequencies are described in Table 1.

Sampling and analysis of these effluent streams provide noble gas radionuclide relative abundance which can then be applied to the noble gas gross activity and gross activity release rate to obtain nuclide specific activities and release rates. The noble gas gross activity released within a specific time period is determined by integrating the stack monitor release rate over the considered time period. If no activity was detected between stack grab samples and l

a significant increase in hourly averages was recorded, the nuclide relative abundance of the last sami,le which indicated the presence of activity was utilized to obtain nuclide specific activities.

Correction factors for the monitors are derived and applied for each sampling period whenever noble gas radionuclides are detected in the effluent stream.

b.

Particulate and Iodines Particulates and iodines are continuously sampled from the three release points utilizing a particulate filter and charcoal cartridge in line with a sample pump (stack monitor pump). These filters and charcoal cartridges are removed and analyzed in accordance with the frequencies specified in Table 1. Analysis is performed to identify and quantify radionuclides utilizing high purity germanium detectors coupled to computerized pulse height analyzers. Given the nuclide specific activity concentrations, process flow rate, and time which the sample covered; the nuclide specific activity released to the environment can be obtained. Due to the continuous sampling process, it is assumed that the radioactive material is released to the environment at a constant rate within the sampling period. Sr-89 and Sr-90 are quantitatively analyzed by counting the digested filter precipitate with a gas flow proportional counter.

Gross alpha analysis is performed using a zine sulfide scintillation counter.

River Hend Static 1997 Regulatory ouide 1.31 Apr;l 27,1998 c.

Tritium i

Tritium grab samples are obtained from the three release points at the specified fiequencies listed in Table 1 utilizing an ice bath condensation collection method. The collected sample is then analyzed utilizing a Liquid Scintillation Counter. Given the tritium concentration, process flow rate, and time period for which the i

sample is obtained, the tritium activity released to the environment can be determined. Due to the frequency of sampling, it is assumed that the tritium is released to the environment at a constant rate within the time period for which the sample is obtained.

2.

Liquid Efiluent Representative grab samples are obtained from the appropriate sample j

recovery tank and analyzed prior to release of the tank in accordance with the frequencies listed in Table 2. Analysis for gamma emitting nuclides (including dissolved and entrained noble gases)is performed utilizing a high resolution germanium detector coupled to a computerized pulse height analyzer. Tritium concentration is determined utilizing a liquid scintillation counter. Sr-89 and Sr-90 are quantitatively analyzed by counting the precipitate with a gas flow proportional counter. Fe-55 is counted with a liquid scintillation counter after digestion of the iron. Gross alpha analysis is performed using a zinc sulfide scintillation counter.

I Given the nuclide specific activity concentration and total volume of the tank that was released, the activity of each nuclide released to the environment can be determined.

Dissolved and Entrained Noble Gases 1 14.2 %

Gross Alpha Radioactivity 1 14.2 %

2.

Gaseous The maximum errors (not including sample line loss) associated with sample flow, process flow, sample collection, monitor accuracy and laboratory analysis are collectively estimated to be:

Determination ofTotal Error The total error (i.e., collective error due to sample collection, laboratory analysis, sample flow, process flow, monitor accuracy, etc.) is calculated using the following equation:

GASEOUS EFFLUENT

SUMMARY

INFORMATION Refer to Tables 3,4 and 5 for " Summation of All Releases" and "Nuclides Released",

j respectively. It should be noted that an entry of"0.00E+00" Curie (Ci) or microcurie /second (uCi/sec) in this section indicates that the concentration of the particular radionuclide was below the Lower Limit of Detection (LLD) as listed in Table 1.

IV.

LIQUID EFFLUENT

SUMMARY

INFOM1ATION i

Refer to Table 6 for " Summation of All faleases and Nuclides Released" It should be noted that an entry of"0.00E+00" Ci or uCi/ml in this section indicates that the concentration of the particular radionuclide was below the Lower Limit of Detection (LLD) as listed in Table 2.

V.

SOLID WASTE Refer to Table 7, for " Solid Waste and Irradiated Fuel Shipments" VI.

RADIOLOGICAL IMPACT ON MAN The total body, skin, thyroid, and other organ doses to a member of the public from the uranium fuel cycle and direct radiation (40CFR190 compliance) calculated in accordance with the ODCM, was less than 25 mrem for the total body, skin and other organs; and less than 75 mrem for the thyroid.

Doses to the maximally exposed individual offsite were calculated using measured effluent data and annual average meteorological data. These doses can be found in Tables 8 through 10.

In addition, doses were calculated for a maximally exposed member of the public inside the site boundary. Parameters and assumptions utilized to make this determination can be found in Table 11. The results of the calculations can be found in Table 12. The maximally exposed member of the public on site was the private driver who delivers an employee to work and returns later that day to pick him/her up. It should be noted that liquid efiluent pathway dose was not considered since these individuals would not engage in activities that would allow exposure to this pathway.

2. Volume Error l

Level indication for processed resins can be determined to +/ 0.5 inches. This correlates to approximately i

1.0%. Container manufacturer stated design tolerance allows for 1.0% deviation from container dimensions. Volume error is not applicable to dry active waste.

3. Representative Sampling Error Sampling error for processed resins is based upon obtaining a representative sample from the waste being pcocessed using an iso-lock sampler. Sampling error from dry active waste is based upon obtaining a representative sample from the material being packaged. This error is estimated to be +/- 10% for all waste types, which is consistent with industry standards.

4. Instrument / Counting Error l

The error caused by sample geometry, counting time, sample activity and instrument background is l

estimated to be +/- 10%. The error for radiological survey instrumentation is estimated to be +/- 20%. This error is applicable to all waste types.

i

5. Dose to Curie Calculations Error The Dose to Curie method used to calculate activity suffers from analytical accuracy in that certain important parameters are neglected. These parameters are geometry of package, measuring instrument chr Neristics, build-up, internal attenuation effect, and external media attenuation. An activity correction facte.s applied to provide adjustment for these factors. This error is applicable to all waste types.
