TURKEY POINT UNITS 3 AND 4 ANNUALRADIOACTIVEEFFLUENT RELEASE REPORT JANUARY 1994 THROUGH DECEMBER 1994 2.0 MAXIMUMPERMISSIBLE CONCENTRATION Water:

In accordance with 10CFR20, Appendix B, Table 2, Column 2, and for entrained or dissolved noble gases as described in 1.1.a of this report.

Air report.

Release concentrations are limited to dose rate limits described in 1.2.a of this 3.0 AVERAGE ENERGY The average energy of fission and activation gases in effluents is not applicable.

4.0 MEASUREMENTS AND APPROXIMATIONS F TOTALACTIVI'IY Allliquid and airborne discharges to the environment during this period were analyzed in accordance with Technical Specification requirements.

The minimum frequency of analysis as required by Regulatory Guide 1.21 was met or exceeded.

V/hen alplI.I, tritiu tn and named nuclides are shown as "- -" curies on the following tables, this should be interpre:ed as '~no activit 'eas detected on the samples using the Plant Technical Specification analysis tecniques to achieve the required Lower Limit of Detection ("LLD")

sensitivity for radioactive effluents.

Aliquots of representative pre-release samples, from waste disposal system, were isotopically analyzed for gamma emitting isotopes on a multichannel analyzer.

Frequent periodic sampling and analysis were used to conservatively determine if any radi':.ctive was being released via the steam generator blowdown system and the storm drain system.

Monthly and quarterly composite samples for the waste disposal system were prepared to give proportional weight to each liquid release made during the designated period of accumulation.

The monthly composite was analyzed for tritium and gross alpha radioactivity. Tritium was determined by use of liquid scintillation techniques, and gross alpha radioactivity was determined by use of a solid state scintillation system. The quarterly composite was analyzed for Sr-89, Sr-90, and Fe-55 by chemical separation.

TURKEY POINT UNITS 3 AND 4 ANNUALRADIOACTIVEEFFLUENT RELEASE REPORT JANUARY 1994 THROUGH DECEMBER 1994 Allradioactivity concentrations determined from sample analysis of a pre-release composite were multiplied by the total represented volume of the liquid waste released to determine the total quantity of each isotope and of gross alpha activity released during the compositing period.

Aliquots of representative samples from the waste disposal system were analyzed on a pre-release basis by gamma spectrum analysis. The resulting isotope concentrations were multiplied by the total volum released in order to estimate the total dissolved gases released.

The liquid waste treatment system is shared by both units at the site and generally all liquid releases are allocated on a 50/50 basis to each unit respectively.

There were no continuous liquid effluent releases above the lower limit of detection for either Unit 3 or Unit 4 during this reporting period and therefore these have been omitted from Table 2 of this report.

TURKEY POINT UNITS 3 AND 4 ANNUALRADIOACTIVEEFPLUENT RELEASE REPORT JANUARY 1994 THROUGI.I DECEMBER 1994 4.2 Gaseous Effluents Airborne releases to the atmosphere occurred from the following sources:

Gas Decay Tanks I

Containment Purges Releases incidental to operation of the plant.

The techniques employed in determining the radioactivity in airborne releases are:

a)

Gamma spectrum analysis for fission and activation gases, b) Removal of particulate material by filtration and subsequent gamma spectrum analysis, Sr-89, Sr-90 determination, and gross alpha determination, c) Absorption of halogen radionuclides on a charcoal filter and subsequent gamma spectral analysis, and d) Analysis of water vapor in a gas sample for tritium using liquid scintillation techniques.

Allgas 1eleases from the plant which were not accounted for by the above methods were cons'rvatively estinIated as curies of Xe-133 by use of the SPING-4 radiation monitors and the Plant Vent process monitor recorder chart and the current calibration curve for that process monitor.

Portions of the gas waste treatment system are shared by both units and generally all gas releases from the shared system are allocated on a 50/50 basis to each unit.

Meteorological data for the period January 1994 through December 1994, in the form of Joint Frequency Distribution Tables, is maintained on site.

TURKEYPOINT UNITS 3 AND 4 ANNUALRADIOACTIVEEFFLUENT RELEASE REPORT JANUARY 1994 THROUGH DECEMBER 1994 4.3 Estimation of Errors a) Sampling Error The error associated with volume measurement devices, flow measuring devices, etc., based on calibration data and design tolerances has been conservatively estimated to be collectively less than + 10%.

b) Analytical Error Our quarterly Q.C. Cross-Check Program involves counting unknown samples provided by an independent external lab. The errors associated with our analysis of these unknown samples, reported to us by the independent lab, were used as the basis for deriving the following analytical error terms:

TURKEYPOINT UNITS 3 AND 4 ANNUALRADIOACTIVEEFFLUENTS RELEASE REPORT TABLE 6 SOLID WASTE AND IRRADIATEDFUEL SHIPMENTS Note 1:

Spent resin and process filter volume indicates the volume of waste shipped directly to the disposal site.

Note 2:

Dry compressible waste volume indicates the volume ofwaste shipped to the disposal site following reduction by a waste processing facility. The volume shipped to the waste processing facility was 1,105.6 m'.

Note 3:

Material shipped to Oak Ridge, Tennessee was consigned to a licensed processing facility for volume reduction or decontamination activities.

The material remaining after processing was shipped by the processor to Barnwell, South Carolina for disposal.

Note 4:

The total curie quantity and the radionuclide composition ofsolid waste shipped &om the Turkey Point Plant Units 3 and 4 are determined using a combination of qualitative and quantitative techniques.

In general, the Turkey Point Plant follows the guidelines in the Low Level Waste Licensing Branch Technical Position on Radioactive Waste Classification (5/11/83) for these determinations.

The most frequently used techniques for determining the total activity in a package are the dose-to-curie method, and inference from specific activity and mass, or activity concentration and volume. Activation analysis may be applied when it is appropriate.

The total activity determination by any of these methods is considered to be an estimate.

The composition of radionuclides in the waste is determined by both on-site analysis for principle gamma emitters and periodic off-site analyses for difficultto measure radionuclides.

The on-site analyses are performed either on a batch basis or routine basis using representative samples appropriate for the waste type.

Off-site analyses are used to establish scaling factors or other methods for estimating difficult to measure radionuclides.

Note 5:

"Principle Radionuclide" refers to those radionuclides contained in the waste in concentrations greater than 0.01 times the concentration of the nuclide listed in Table 1 or 0.01 times the smallest concentration for the nuclide listed in Table 2 of 10 CFR 61.55.

Note 6:

"Type of Waste" is generally specified as described in NUREG 0782, Draft Environmental Impact Statement on 10 CFR 61, "Licensing Requirements for Land Disposal of Radioactive Waste".

Note 7:

"Type of Container" refers to the transport package.

0 The dose to a person from tritium via the vegetation (fruit and vegetables),

air-grass-cow-milk, or air-grass-cow-meat pathways is evaluated at the nearest garden (with residence assumed) 3.6 miles west northwest of the plant.

At that location, the reference atmospheric dis-persion factor is X/Q = 1 x 10 sec/m The dose commitment via a given pathway as a result of measured discharges from a release point is accumulated with (26) where:

the dose commitment to organ n of a person in age group a k

the counting index; it may represent either:

p, analysis of a grab sample w,

a weekly sample analysis m,

a monthly composite analysis, or q,

a quarterly composite analysis Effluent Gas Monitor Alarm Set pints The radioactive gaseous effluent monitoring instrumen-tation channels alarm setpoints are set in accordance with Specification 3.3.3.6, to ensure the limits of Specification 3.11.2.1 are not exceeded.

Each radioactive noble gas effluent monitor setpoint is derived on the basis of total body dose equivalent rate at or beyond the site boundary.

The setpoint derivation assumes that noble gas releases occur at ground-level.

For the purpose of deriving a setpoint, the distribution of radioactive noble gases in an effluent stream may be determined in one of the following ways:

35 08/09/94

Sg A factor to allow for multiple sources from different or common release points.

The allow-owable operating setpoints will be controlled administratively by assigning a fraction of the total allowable release to each of the release sources.

Each monitoring channel has a unique response, h, which is determined by the instrument calibration.

Atmospheric dispersion depends upon the local atmospheric conditions.

For the purpose of calculating a radioactive noble gas effluent monitor setpoint, the atmospheric dispersion

factor, y/Q, will be based on prevailing meteorological conditions or on reference meteorological conditions.

The minimum atmospheric dispersion off-site derived from reference meteorological conditions at the site boundary is 5.8 x

10~ sec/m't a location 1950 meters south southeast of the plant.

The applicable dose conversion factors, DF;, for deriving setpoints are in Table 3-5.

The limiting factor for Equation 27 is the total body dose rate limit of 500 mrem/year which is included in the 1.06 conversion factor.

The use of the total body dose assumes that the total body dose will be the controlling dose rate and the dominant contributor to this dose will be Xe-133.

Each iodine and particulate effluent monitor setpoint may be calculated using the equation below, or a method which gives a

lower setpoint value.

Since the iodine and particulate channels are not required by Technical Specification 3.3.3.6, the primary method to ensure Technical Specification 3.11.2.1 is met is the performance of the sampling and analysis program in table 4.11-2 and the noble gas alarm setpoints.

3.7 Pro'ected Dose for Gaseous Effluents Technical Specification 3.11.2.4 requires that the gas decay tank system shall be operable and used to reduce radioactive materials in gaseous waste prior to their discharge if the projected gaseous effluent dose per reactor due to gaseous effluent releases to areas at and beyond the site boundary when averaged over 31 days exceeds 0.2 mrad for gamma radiation and 0.4 mrad for beta radiation, and the ventilation exhaust treatment system shall be used to reduce radioactive materials in gaseous waste prior to their discharge if the projected gaseous effluent dose per reactor due to gaseous effluent releases to areas at and beyond the site boundary when averaged over 31 days exceeds 0.3 mrem to any organ.

Technical Specification 4.11.2.4.1 requires the

doses, to areas at and beyond the site
boundary, due to radioactive material released in gaseous effluent to be projected at least once per 31 days.

This requirement is satisfied by extrapolating the dose to date during the current month to include the entire month.

The dose to date is calculated as described in Sections 3.4.1, 3.4.2, and 3.5.2.

The dose is projected with the relation:

31 'D X

(30) where:

P

= the projected dose during the month, (mrem) 31 = number of days in a calendar

month, (days)

X

= number of days in current month to date represented by available radioactive effluent sample, (days)

D

= dose to date during current month calculated according to Sections

3. 4. 1,
3. 4. 2, and
3. 5. 2, (mrem), i.e.,
gamma, beta, or organ dose respectively.

Alternately, the monthly dose may be projected by computing the dose accumulated during the most recent month and assuming the result represents the projected dose for the current month.

The dose during the proceeding month will be computed as described in Sections 3.4.1, 3.4.2, and 3.5.2.

The limiting factor when using equation 27 to determine a setpoint is the total body dose rate limit of 500 mrem/yr which is included in the 1.06 conversion factor.

The use of total body dose assumes that the total body dose will be the controlling dose rate and the dominant contributor to this dose will be Xe-133.

times the monitor Background at the time of Calibration From ODCM Section 3.6 or default maximum From ODCM Section 3.6 Equation 28 is based on limiting dose due to iodine, tritium and particulates to less than 1500 mrem/year.

These factors in this equation assume that a hypothetical infant located at the site boundary where the minimum atmospheric dispersion occurs is the receptor.

This approach assures the most conservative estimate of dose.

When this assumption is used, the infant thyroid via the inhalation pathway is the critical organ and controlling pathway respectively.

The dose transfer factor is based solely on the radioiodines (I-131, I-133) because the radioiodines contribute essentially all of the dose to the infant s

thyroid, when estimating dose due to
iodines, tritium, and particulates with half lives greater than 8 days.
