EFFLUENT AND WASTE DISPOSAL SUPPLEMENTAL INFORMATION

1. Regulatory Limits 1.1 For Liquid Waste Effluents A. The concentration of radioactive material released from the site shall be limited to the concentrations specified in 10 CFR Part 20 Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 micro-Curies/ml total activity.

B. The dose or dose commitment to a MEMBER OF THE PUBLIC from radioactive material in liquid effluents released, from each reactor unit, to UNRESTRICTED AREAS shall be limited to:

During any calendar quarter to <= 1.5 mrems to the Total Body and to <= 5 mrems to any organ, and During any calendar year to <= 3 mrems to the Total Body and to <= 10 mrems to any organ.

1.2 For Gaseous Waste Effluents:

A. The dose rate in UNRESTRICTED AREAS due to radioactive materials released in gaseous effluents from the site shall be limited to:

For Noble Gases: <= 500 mrems/yr to the total body and

<= 3000 mrems/yr to the skin, and For Iodine-131, Iodine-133, Tritium, and all radionuclides in particulate form with half-lives greater than 8 days:

<= 1500 mrems/yr to any organ.

• B. The air dose due to noble gases released in gaseous effluents from each reactor unit, to areas at and beyond the SITE BOUNDARY shall be limited to the following:

During any calendar quarter, to <= 5 mrads for gamma radiation,and

<= 10 mrads for beta radiation and, during any calendar year to

<= 10 mrads for gamma radiation. and <.= 20. mrads for beta radiation.

• C. The dose to a MEMBER OF THE PUBLIC from Iodine-131, Iodine-133, Tritium, and all radionuclides in particulate form, with half-lives > 8 Days in gaseous effluents released, from each reactor unit to areas at and beyond the site boundary, shall be limited to the following:

During any calendar quarter to <= 7.5 mrem to any organ, and During any calendar year to <= 15 mrem to any. organ.

• The calculated doses contained in a semi-annual report shall not apply to any STS LCO. The reported values are based on actual release conditions instead of historical conditions that the STS LCO dose calculations are based on. The STS LCO dose limits are therefore included in Item 1 of the report, for information only

EFFLUENT AND WASTE DISPOSAL SUPPLEMENTAL INFORMATION (Continued)

2. Maximum Permissible Concentrations Water: As per 10 CFR Part 20, Appendix B, Table II, Column 2, except for entrained or dissolved noble gases as described in.

1.1.A of this report.

Air: Release concentrations are limited to dose rate limits described in 1.2.A. of this report.

3. Average Energy of fission and activation gases in gaseous effluents is not applicable.

4. Measurements a'nd approximations of total radioactivity Where alpha, tritium, and listed nuclides are shown as zero Curies released, this should be interpreted as "no activity was detected on the samples using the Plant Technical Specification analyses techniques to achieve required Lower Limit of Detection (LLD) sensitivity for radioactive effluents".

A summary of liquid effluent accounting methods is described in Table 3.1.

A summary of gaseous effluent accounting methods is described in Table 3.2.

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

The most frequently used techniques for determining the total curie-quantity-in-a package are the dose to curie methods and the (concentration) x (volume or mass) calculations. Where appropriate, engineering type activation analyses may be applied. Since each of the above methodologies involves to some extent qualitative parameters, the total curie quantity is considered to be an estimate.

The composition of radionuclides in the waste is determined by both on-site analyses for principal gamma emitters and periodic off-site analyses for other radionuclides. The on-site analyses are performed either on a batch basis or on a routine basis using reasonably representative samples as appropriate for the waste type. Off-site analyses ar used to establish scaling factors or other estimates for radionuclides such as 3H, 14C, 99TC, 129I, TRU, 241Pu, 242Cm, 63Ni, 55Fe, and 90Sr.

NOTE 2: "Principal Radionuclides" refer to those radionuclides contained in the. waste in concentrations greater than .01 times the concentration of the nuclides listed in Table 1 or .01 times the smallest concentration of the nuclides listed in Table"2 of-10 CFR 61.-

NOTE 3: "Type of Waste" is generally specified as described in NUREG 0782, Draft Environment Impact Statement on 10 CFR 61, "Licensing Requirements for Land Disposal of Radioactive Waste".

NOTE 4: "Type of Container" refers to the transport package.

NOTE 5: The volume and activity listed for Dry Compressible Waste represent the quantity of material that during the reporting period was sent to the Barnwell, South Carolina burial facility. This material was shipped to a contracted vendor for volume reduction prior to final disposal at the Barnwell, South Carolina burial facility. During the reporting period, four shipments of Dry Compressible Waste (4,140 cubic feet, 1.814 E+0 curies) were made from the St. Lucie Plant to the volume reduction facility. This material was shipped via "Sole Use Truck in non-specification strong tight packages.

23

NOTE 6: The volume and activity listed for non-compressible metal represent the quantity of material that during the reporting period could not be recycled by the contracted vendor and required disposal at the Barnwell, South Carolina burial facility. During the reporting period, two shipments of non-compressible metal waste (1,280 cubic feet, 2.097 E-3 curies), and secondary bead resin (519 cubic feet, 1.608 E-5 curies) were made from the St. Lucie Plant to the volume reduction facility. This material was shipped via "Sole Use Truck" in non-specification strong tight packages.

Attachment A

1) Description and analysis of event On January 28, 1993 the nitrogen system was in normal alignment, and the Air Ejector I 1 Exhaust was realigned directly to the Atmosphere instead of its normal alignment to the Plant Vent.

This realignment was performed to prevent steam from flowing into a static Plant Vent during Ventilation Flow Testing being performed in the Reactor Auxiliary Building(RAB).

On January 29, 1993 at 0445, with the Reactor operating at full power, the Air Ejector Il (SJAE) Rad Monitor alarmed and Control Room personnel alerted Chemistry personnel. The SJAE exhaust was then aligned to the Plant Vent Exhaust, a Technical Specification Continuous Release Monitored Pathway. Chemistry sampled the Steam Generator blowdown for. radioactivity, detecting a trace of Xe-133.

A qualitative gas grab sample on the SJAE exhaust gases indicated:

1) noble gas radioactivity was present, 2) the gas isotopic mix indicated that the source was not from the Reactor Coolant System, but was typical of decayed gas from a gas decay tank. A quantitative gas sample was obtained on the Air Ejector Monitor.

Operations personnel immediately checked current plant conditions and confirmed the suspected pathway could have occurred when the nitrogen system supply pressure dropped when the Condensate Storage Tank(CST) Atmospheric Water Seal lost integrity. This put a large demand on the nitrogen cover gas supply to this tank and Decay Tank 1B had back flowed a small amount (5 psig total loss based on observation of previous pressure in the tank) through V6596 and into the nitrogen supply. The radioactive gas was detected by the SJAE Monitor since nitrogen gas is injected into the condenser for dissolved oxygen removal'". The: nitrogen- supply valve V-6596 to GDT 1B was then checked closed and the nitrogen supply root valve V-6788 was closed for double valve isolation to insure the release path was terminated.

Gas Decay Tank 1B was sampled as the source of the Unplanned Release as per procedure C-72. The analyses included Gas, Iodine, Particulate, and Tritium to account for all activity that could have been present in the source. Noble gas activity was the only type of activity present in the tank.

Plant Work Order (PWO I 93002828) was issued to repair V-6596.

Review of Technical Specification Limits:

The Air Effector Exhaust Monitor is only a noble gas activity monitor and Technical Specifications do not require continuous sample collection for Iodine and Particulates. It is the policy of the plant to align the SJAE Exhaust to the continuous Iodine and Particulate sampler in the Plant Vent when th'er'e is a primary to secondary leak. The SJAE Exhaust was aligned to the Plant Vent upon receipt of the SJAE alarm until the source of the radioactivity could be identified. The identified source, Gas Decay Tank 1B, was analyzed for Iodine Particulates, and Tritium to ensure that all activity was accounted for in this event.

This event was an unplanned batch release.

The calculated release rate for the event was 5.1E-04 Ci/sec which is approximately a factor of 690 lower than the Site Limit of 0.35 Ci/sec.

No Technical Specification Release Rate Limits were exceeded.

All required sample surveillances were performed during this event.

ATTACHMENT B UNPLANNED LIQUID EFFLUENT RELEASE of June/July 1993

ATTACHMENT B Description and analysis of event On 6/15/93 Operations noted a decreasing trend in Refueling'Water Tank (RWT) level and began a search of interconnecting systems for the leakage source. The leakage was approximately 1.5 gpm. On 6/29/93, after extensive interconnecting system alignment and leakage checks, Operations reported that the volume loss could not be located. A systematic search was initiated which involved independent alignment checks, isolation of individual sections of piping and a line by line walkdown of interconnecting systems.

Again, no cause of the RWT volume loss could be found and the focus of the investigation shifted to the possibility of a leak in the RWT shell.

On 7/6/93 Monitoring Wells in the vicinity of the RWT were sampled specifically for Boron and Tritium. Test results were positive which indicated that the leakage was from the RWT shell. Voluntary notification to the State of Florida Department of Environmental Regulation of the Tritium release was made by Juno Environmental on 7/7/93. The NRC was notified in accordance with 10CFR50.72B.VI where an inadvertent release of radioactively contaminated materials occured and another government agency was notified.

A remote controlled submersible was placed in the RWT to perform a visual survey on'/10/93. Some minor debris was found, but no leakage site was identified. On 7/12/93 a contractor with Acoustic Leak Detection experience arrived on site. External acoustic data collection was performed. Analysis of the data was completed on 7/13/93. The data indicated several"possible" leakage'sites.'-

Divers entered the RWT on 7/15/93 to locate the leakage sites. The remote controlled submersible was put into the RWT to perform internal acoustic monitoring. Divers located a single leak at a pit location in the RWT on 7/16/93. Divers repaired the leakage site utilizing an epoxy repair with an Aluminum backing plate approved by Engineering. The repair method is a recommended practice per EPRX Underwater Maintenance Guide NP-7088. Permanent, repair of tank bottom is planned for the 1994 Unit 1 outage.

On 7/17/93 cleanup of debris was completed. A random sample Ultrasonic Test (UT) of the RWT bottom was also performed. Results of the UT indicated that there were no areas of general thinning in the bottom aluminum liner. Operations personnel and additional acoustic testing verified that RWT level stabilized upon completion of the repair.

The liquid release was accounted for in accordance with Technical Specifications Table 4.11-1b, Continuous Releases, and will be reported in the July-December 1993 SemiAnnual Release Report once Sr89/90 and Fe55 composite analysis is done.

Analysis shows 55,000 gallons with approximately 6.5 curies of Tritium and 0.037 curies of gamma emitting solids were released to the groundwater table which is 14 feet below ground surface.

There are no drinking water wells on site or on the Island. The magnitude of the release was equivalent to a normal batch liquid release. The groundwater movement is towards our circulating water system canals and then to the Atlantic Ocean. Therefore there will be no adverse impact on the health and safety of the public as a result of the release.

Records of this event will become part of the site decommissioning files.

'his manual provides the methodology to calculate radiation dose, to individuals in the vicinity of the St. Zucie site, fram radioactive gaseous and liquid effluents. It also provides methodology for calculating effluent monitor setpoints and allowable release rates to ensure- campliance with the STS and 10CFB20 release criteria. The in-plant procedures specify what sections of the,OIXK should be completed- to calculate the dose to an individual.

The ODCM follaws the methodology and models= suggested by NUREG-0133 (November, 1978) and Rectulatory Guide 1.109.. Simplifying assumptions have been applied where applicable to provide a more workable document for Rd St f calculation methods may be used fram those presented as long as the overall methodology does nat change or as long as the alternative methods provide results that are more limiting. Also, as available, the most up-

The description that follows is a brief surmaary for dose calculation purposes:

The St. Zucie Plant is located on an island surrounded on two sides'by the Atlantic Ocean and the Indian River, an estu-ey of the Atlantic Ocean. Normally, all radioactive liquid releases enter the Atlantic Ocean where the CirnQating Water Discharge Pipe terminates on the ocean floor at a point approximately 1200 feet offshore. No credit is taken for subsequent muring of the discharge flume with the ocean. The diffusion of radioactive material into the ocean is dependent on the corditions of tide, wind, and same eddy currents caused by the Gulf S~mn. 'Ihe conditions are sufficiently rardam enough to distribute the discharges over a wide area and no concentrating effects are assuHled o

%here are no direct disch;mme paths for liquid effluents to either of the north or south private property bound-~ lines.

The Big Mud Cret& (part of the Indian River) does connect to a normally loci<ed shut dam, that is intended to provide an emergency supply of circulating water to the Intake Cooling Water

~

Canal in the event a Hurricane causes blockage of the Intake Canal. No radioactive water could be disch-~ed directly into the Intake Cooling Water Canal because all plant piping is routed to the discharge canal and no back flow can occur. Consult the HJSAR for a detailed description of characteristics of the water hd p Only those nuclides that appear in the Liquid Dose Factor Tables will be considered for dose5-:calculation.

1.2 Source Discussion Technical specification 3.11.1.1 recpures that the sanpling and analysis reeQts of liquid waste (prior to discharge) be used with calculation methods in the in-plant procedures to assure that the concentration of liquid radioactive material in the uruwstricted areas will not exceed the concentrations specified in 10CFR20, Appendix B, Table II. This section presents the calculation method to be used for this determination. This method only addresses the calculation for a specific release source. The in-plant procedures will provide instructions for deteratuning that the summation of each release source's F values do not exceed the site's 10CFR20 MPC limit. The values for release rate, dilution rate, etc.,

Based on the radionuclide distribution typical in radioactive effluents, the calculated doses to individuals are damiLnated by the radionuclides Fe-59, Co-58, Co-60, Zn-65, Nb-95, Cs-134 and Cs-137. 'these nuclides typically contribute over 95< of the total body dose and over 90% of the GI-LLX dose, which is the critical organ. 'Iherefore, the dose canunitment due to radioactivity in liquid effluents may be reasonably evaluated by limiting the dose calculation process to these radionuclides for the adult total body and adult GI-IZZ. To allow for any unexpected variability in the radionuclide distribution, a conservatism factor of 0.6 is intnxtuced into the equation.

After calculatirg the dose based on these 7 nuclides, the cumulative dose should be divided by 0.6, the conservatism factor. (i.e., DI = Dl/0.6). Refer to Appendix B for a detailed evaluation and explanation of this limited analysis approach.

Lhe description that follaws is a brief summary for dose calculation purposes only). The St. tucie Plant is located on an island surtzazded on two sides by the Atlantic Ocean and the Indian River, an estuary of the Atlantic Ocean. Private pszperty adjoins the plant site in the north and south directions. A meteorological tawer is located north of the plant near the site property line. 'Jhere are 16 sectors, for dose calculation purposesg divided into 22.5'ach. 'Ihe met tower is calibrated such that a zero degree bearing coincides with TRUE NOKK. A bearing of zero degrees dissects the north sector such that bearings of 348.75'nd 11.25'efine the boundaries of the north sector. %he nearest distance to private property occurs in the north sector at approximately 0.97 miles. For ease of calculation, this 0.97 mile radius is assumed in all dit~ions, although the real Unrestricted Area Boundary is defined in Figure 5.1-1 of the STS. Doses calculated aver water are-m do not apply to the STS ZCO's or the annual report and may be listed as O.W.

tucie Site and are incorporated into the historical MET tables (Tables M5, M6, and M7) in Appendix A of this manual. It was deterauned that these two years are representative data for this locale.

Dose Calculations Dose calculations for Technical Specification dose limits are normally calculated using historical MET data and receptor location(s) which yield calculated doses no lower than the real location(s) experiencing the most exposure. Actual MET data factors are calculated and used in dose calculations for the Semi-annual reports.

Live MET data and hour-by-hour dose calculations are beyond the scope of this manual. Historical information and conservative receptor locations, etc., are only used for ease of STS ZCQ dose limit calculations. Dose calculations for PIS dose limits may be performed using actual MET data, real receptor locations, and sector wind frecpency distribution if desired. Any dose calculations performed with actual data should note the source of the data in the annual report. Actual MET data reduction should be performed in accordance with Regulatory Guide 1.111, Revision 1 and should incorporate Reaction Correction Factors fram Table M-4 of this manual.

For purposes of calculations, the appropriate meteorological dispersion (X/Q) fram Table M-1 should be used. Tech. Spec. 3.11.2.2 vapxires that the doses be evaluated once per 31 days, (i.e.,

monthly) . She quarterly dose limit is 5 mrads, which corresponds to a monthly allotnent of 1.7 mrads. If the 1.7 mrads is substituted, for D~, a cunaQative noble gas monthly release cbjective can be cal ated. This value is 36,000 Ci/month, noble gases.

As long as this value is not exceeded in any month, no additional calculations are needed to verify compliance with the qu;overly ncble gas release limits of Specification 3.11.2.2. Also, the gartttna air dose is more limiting than the beta air dose. Therefore, the beta air dose does not need to be calculated per Section 2.5 if the M ff dose factor is used to detm+Lne the garttma air dose.

2.7 Pro'ect'ose for Radioactive Gaseous Effluents Discussion Tech. Spec. 3.11.2.4 requires that the gaseous radwaste treatment system be used to reduce radioactive materials in waste prior to discharge when the'projected-dose-due to gaseous effluents would exceed 0.2 mrad for gamtta radiation and 0.4 mrad for beta radiation. The following calculation method is provided for determining the projected doses. 'Ibis method is based on using the results of the calculations performed in Sections 2.4 and 2.5.

1. Obtain the latest results of the monthly calculations of the ganma air dose (Section 2.4) and the beta air dose if performed (Section 2.5) . 'Ihese doses can be obtained fram the in-plant'. records.

2. Divide these doses by the nunber of days the plant was operational during the month.

3. Multiply the quotient by the number of days the plant is projects to be operational during the next month. The product is the projected dose for the next month. The value should be adjusted as needed to account for any ch;ages in failed-fuel or other identifiable operating conditions that could significantly alter the a~ releases.

4. If the projected doses are >0.2 mrads gamtna air dose or 0.4 mrads beta air dose, the appropriate subsystems of the gaseous radwaste system shall be used to reduce the radioactivity levels prior to release.

The following approach should be used to demonstrate campliance with these dose limits. This approach is based on NUR1.'G-0133, Section 3.8.

3.1 Evaluation Bases Dose evaluations to demonstrate compliance with the abave dose limits need only be performed 2.4 2.6 if the quarterly doses calculated in Sections twice the dose limits of Tech. Specs.

1.4, and exceed 3.11.1.2.a, 3.11.1.2.b, 3.11.2.2a, 3.1.2.2b, 3.11.2.3a, and 3.11.2.3b respectively; i.e., cgm~ly doses exceeding 3 mrem to the total body (liquid releases), 10 mrem to any organ (liquid releases), 10 mrads gamma air dose, 20 mrads beta air dose, or 15 mrem to the thyroid or any organ fram radioiodines and particulates (atmospheric releases). Otherwise, no evaluations are required and the remainder of this section can be canitted.

3.2 Doses From Li id Releases For the evaluation of doses to real individuals fram liquid releases, the same calculation method as employed in Section 1.4 will be used.

However, more realistic assumptions will be made concernizg the dilution and ingestion of fish 'and shellfish by individuals who live and fish in the area. Also, the results of the Radiological Environmental Monitoring program will be included in determining more realistic dose to these real people by praviding data on actual measured levels of plant related radionuclides in the environment.

3.3 Doses From A heric Releases"" "*

For the evaluation of doses to real individuals fram the atmospheric releases, the same calculation methods as employed in Section 2.4 and 2.6 will be used. In Section 2.4, the total body dose factor (Ki) should be substituted for the ~zaa air dose factor (Mi) to determine the total body dose. Othexwise the same calculation sequence applies. However, more realistic assumptions will be made concerning the actual location of real individuals, the meteorological conditions, and the consumption of food (e.g., milk) .

Data obtained fram the latest land use census (Tech. Spec. 3.12.2) should be used to determine locations for evaluating doses. Also, the results of the Radiological Environmental Monitoring program will be included in determining more realistic doses to these real people by providing data on actual me-mured levels of radioactivity and radiation at locations of interest.

'Ihe radioactive liquid effluents for the years 1978, 1979, and 1980 were evaluated to determine the dose contribution of the radionuclide distribution.

Ibis analysis was performed to evaluate the use of a limited dose analysis for determining environmental doses. Limiting the dose calculation to a few selected radionuclides that contribute the majority of the dose provides a simplified method of determining 'compliance with the dose limits of Technical Specif ication 3. 11.1.2.

Tables B-1 and B-2 present the results of this evaluation. Table B-1 presents the fraction of the adult total dose contributed by the major radionuclides. Table B-2 pcs body the same data for the adult. GI-LLE dose.

'Ihe adult total body and adult GI-LLI were detezzdned to be the limiting doses based on an evaluation of all age groups (adult, teenager, child, and infant) and all organs (bone, liver, kidney, lung, and GI-LIZ). As the data in the tables st, the radionuclides Fe-59, Co-58, Co-60, Zn-65, Cs-134, and Cs-137 dominate the total body dose; the radionuclides, Fe-59, Co-58, Co-60, Zn-65, and Nb-95 dominate the GI-LLE dose. In all but one case (1979-fish, GI-IZZ dose) these radionuclides contribute 90% or more of the total dose. If for 1979 the fish and shellfish pathways are combined as is done to determine the total dose, the contribution fmm these nuclides is 84% of the total GI-LLK dose o

'Iherefore, the dose cammitrMnt due to radioactive material in liquid effluents can be reasonably estimated by limiting the dose calculation to the radionuclides, Fe-59, Co-58, Co-60, Zn-65, Nb-95, Cs-134, and Cs-137, which cumulatively contribute the majority of the total dose calculated by using all radionuclides detect. This limited analysis dose assessment method is a simplified calculation that provides a-reasonable evaluation of. doses due to liquid radioactive effluents and allows for an estimate of Fe-55 contribution to dose.

Tritium is not included in the limited analysis dose assessment for liquid releases because the potential dose resulting from normal reactor releases is negligible and is essentially independent of radwaste system operation. 'Ihe amount of tritium release annually is about 300 curies. At St. Zucie, 300 Ci/yr releam6 to the Atlantic Ocean produces a calculated whole body dose of 5 X 10 mrem/yr via the fish and shellfish pathways. 'Ihis amounts to less than 0.001% of the design objective dose of 3 mrem/yr.

Furthermore, the release of tritium is a function of operating time and paver level and is essentially unrelated to radwaste system operation.

A- 'Ihe dose due to Iron -55 made it necessary to change the conservatism factor from 0.8 to 0.6, which was done on Revision 7 to the ODCM, based on early 1986 data.

Page 78 of 88 ST. WCIE OPERATING HKCEK1EK NO. C-200, REVISION 11 PZANI'HEMISTRY OFFSITE DOSE CAICUZATION MANUAL ODCH APHXDIX C Technical Bases for Effective Dose Factors Overview The evaluation of doses due to releases of radioactive material to the atmosl&exe can be simplified by the use of effective dose transfer factors instead of using dose factors which are radionuclide specific. 'Ihese effective factors, which are based on the typical radionuclide distribution in the releases, can be applied to the total radioactivity released to approximate the dose in the environment, i.e., instead of having to sum the isotopic distribution multiplied by the isotope specific dose factor only a single multiplication (I( ffg Meffg or Neff) times the total quantity of radioactive material released would be needed. This approach provides a reasonable estimate of the actual dose while elimbmting the need for a detailed calculational technique.

Determination of Effective Dose Factors

'Ihe effective dose transfer factors are based on past operating data.

'Lhe radioactive effluent distribution for the past years can be used to derive single effective factors by the following equations:

Ni = the air dose factor due to beta emissions from each noble gas radionuclide i To deteraune the appropriate effective factors to be used and to evaluate the degree of variability, the atznospheric radioactive effluents for the past 3 years have been evaluated. Tables C-1 and C-2 present the results of this evaluation.

As can be seen from Tables C-1 ard C-2, the effective dose transfer factors varies little from year to year. The max&num o~ed variability fram the average value is 18.. This variability is minor considering other areas of uncertainty and conservatism inherent in the environmental dose calculation models o To provide an additional degree of conservatism, a factor of 0.8 is irrtroduced into the dose calculation process when the effective dose transfer factor is used. 'Ihis added conservatism provides additional assurance that the evaluation of doses by the use of a single effective factor will not significantly und~imate any actual doses in the envirorment.

Reevaluation The doses due to the gaseous effluents are evaluated by the more detailed calculation methods (i.e., use of nuclide specific dose factors) on a yearly basis. At this time a camparison can be made between the simplified method and the detailed methcd to assure the overall reasonableness of this limited analysis approach. If this colttparison indicates that the radionuclide distribution has changed significantly causing the simplified method to und~imate the doses by more than 20%, the value of the effective factors will need to be reexamined to assure the overall acceptability of this approach. However, this reelmnination will only be needed if the doses as calculated by the detailed analysis exceed 50~ of the design bases doses (i.e.,

greater than 5 mrads gamma air dose or 10 mrads beta air dose) .

In any case, the appropriateness of the A ff value will be periodically evaluated to assume the applicability of a single effective dose factor for evaluating environmental doses.

Technical Bases for Eliminating Curie Inventory Limit For Gaseous Waste Storage The NRC Standard Technical Specifications include a limit for the amount of radioactivity that can be stored in a single waste gas storage tank. 'Ibis curie inventory limit is established to assure that in the event of a tank failure releasing the radioactivity to the environment the resulting total body dose at the site bourdazy would not exceed 0.5 rem.

For St. tucie, the inventory limit in the waste gas storage tank has been determined to be approximately 285,000 curies (Xe-133, equivalent) . An allowable primary coolant radioactivity concentration is established by the Appemiix A Technical Specifications which limits the primary coolant radioactivity concentrations to 100/E with E being the average energy of the radioactivity in Mev. This equation yields an upper primary coolant gross activity limit of about 160 uCi/ml. By applying this activity concentration limit to the total liquid volume of the primary system, a total activity limit can be deterndned. For St. tucie the primary system volume is about 70,000 gallons, which yields a limiting total inventory of approximately 43,000 Ci.

By assuming a typical radionuclide distribution an equivalent Xe-133 inventory can be determined. Table D-1 provides the typical radionuclide (ncble gases) distribution and the Xe-133 equivalent con~tration. The

~

equivalent concentration is deteanined by multiplying the radionuclide concentration by the ratio of the nuclide total body dose factor to the Xe-133 body dose factor. Sun>ning all the individual radionuclide equivalent concentrations provides the overall reactor coolant Xe-133 equivalent concentration. The data shor that the equivalent concentration is a factor of 2 larger than the gross concentration (i.e., 24 uCi/gm total versm 47 uCi/gm equivalent) . The resulting Xe-133 equivalent curie inventory of the reactor coolant system is approximately 86,000 Ci.

Therefore, even if the total primary system at the maximum Tech. Spec.

allowable concentration was degassed to a single wa.~ gas decay tank, the tank curie inventory would be well below the 285,000 Ci limit. Based on this evaluation, the curie inventory limit on a single waste gas storage tank cannot exceed the Technical Specification requ~~nent.
