PRAIRIE ISLAND NIICILEAR GENERATING PLANT OFF-SITE RADIATION DOSE ASSESSMENT FOR January through December 2001 An Assessment of the radiation dose due to releases from Prairie Island Nuclear Generating Plant during 2001 was performed in accordance with the Offsite Dose Calculations Manual as required by Technical Specifications. Computed doses were well below the 40 CFR Part 190 Standards and 10 CFR Part 50 Appendix I Guidelines.

Off-site dose calculation formulas and meteorological data from the Off-site Dose Calculation Manual were used in making this assessment. Source terms were obtained from the Annual Radioactive Effluent and Waste Disposal Report prepared for NRC review for the year of 2001.

Off-site Doses from Gaseous Release Computed doses due to gaseous releases are reported in Table 1. Critical receptor location and pathways for organ doses are reported in Table 2. Doses are a small percentage of Appendix I Guidelines.

Off-site Doses from I iguid Release Computed doses due to liquid releases are reported in Table 1. Critical receptor information is reported in Table 2. Doses, both whole body and organ, are a small percentage of Appendix I Guidelines.

Doses to Individuals Due to Activities Inside the Site Boundary Occasionally sportsmen enter the Prairie Island site for recreational activities. These individuals are not expected to spend more than a few hours per year within the site boundary. Commercial and recreational river traffic exists through this area.

For purposes of estimating the dose due to recreational and river water transportation activities within the site boundary, it is assumed that the limiting dose within the site boundary would be received by an individual who spends a total of seven days per year on the river just off shore from the plant buildings (ESE at 0.2 miles). The gamma dose from noble gas releases and the whole body and organ doses from the inhalation pathway due to Iodine 131, Iodine-133, tritium and long-lived particulates were calculated for this location and occupancy time. These doses were reported in Table 1.

Doses to Individuals Due to Effluent Releases from the ISFSI Two fuel casks were loaded and placed in the storage facility during the 2001 calendar year. The total number of casks in the ISFSI is fourteen. There has been no release of radioactive effluents from the ISFSI.

CURRENT ODCM REVISION The Offsite Dose Calculations Manual was revised this year. The current revision is 16. The revision date is August 7, 2001. A copy is included with this report.

AIRBORNE ABNORMAI. RELEASE There were no abnormal airborne releases for the year 2001.

Radiation Effluent Monitoring Sampling Deviation On July 15, 2001, 122 CVCS Monitor Tank was recirculating through an ion exchanger for clean up. It was last sampled at 08:30. The tank was removed from the ion exchanger and placed on recirculation, for sample, at 1430. Required recirculation time to obtain a representative sample is 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months . The tank should not have been sampled for release prior to 17:30. The tank was released at 15:56 based on the results of the 0830 sample taken while the tank was on recirculation through the ion exchanger.

Cause: 122 CVCS Monitor Tank had been placed on recirculation, through the ion exchanger, for further processing. The Rad Waste engineer requested the Chemistry Group sample the tank. His intent was to monitor the processing of the tank. The chemistry technician interpreted this direction as a request to sample the tank for release.

The intent of recirculation, prior to sampling for release, is to place a waste tank on recirculation, while not being processed through an ion exchanger. Processing through an ion exchanger may contribute or remove activity. The tank should have been placed on recirculation without an ion exchanger in line for the purpose of obtaining a representative sample.

The cause of this event was poor communication by the Rad Waste Engineer and lack of a questioning attitude by the chemistry technician.

Corrective The event was documented and assessed by Chemistry Management through the Actions: Condition Reporting System, Condition Report number 20015745.

The event was presented to all members of the chemistry group.

The importance of providing complete and specific instructions to both operations and chemistry group members was emphasized to the Radioactive Waste Engineer.

The Liquid Waste Tank Release procedures have been revised to specify that recirculation for sampling is to be completed with the tank recirculating to itself and not through an ion exchanger or filter.

Significance: When the event was discovered, a sample was taken from the water left in the bottom of the tank. This sample was analyzed and results were compared to results of the 08:30 sample upon which the release was based. The results indicated that the 08:30 sample was representative of the release. The additional results were attached to the release file paperwork. The actual release activity was the same as the release activity upon which permission to release the tank was based and did not impose upon the health and safety of the public.

Incorrect Efficiencies Generate Incorrect Tritium Values Ventilation stack tritium samples are collected continuously by silica gel. The silica gel is changed monthly and analysis is by liquid scintillation on the Beckman LS5801. Data review indicated that the silica gel tritium program efficiency had change by a factor of seven to eight. This change had gone unnoticed for the months of May through October. Operation of the Beckman LS5801 and validity of the silica gel tritium results were investigated.

Analysis of silica gel is only performed once per month. The last documented calibration of the Beckman LS5801 stored a typical efficiency value. It was determined that some time between the May 6th silica gel samples and the June 2nd samples, the stored efficiency was changed to an incorrect value.

Cause: The event could not be traced to calibrations performed or a vendor visit. The Beckman LS5801 has two stored programs, one for tritium analysis of a water sample and one for silica gel samples. Data comparison between the water analysis program and the silica gel analysis program indicates that data was entered improperly during an attempt to perform a semi annual tritium in water analysis calibration. The tritium in water calibration data was applied to the silica gel program.

Corrective The event was documented and assessed by Chemistry Management through the Actions: Condition Reporting System, Condition Report number 200185078.

A new calibration curve was generated for the silica gel analysis program.

The airborne tritium values for the period of May through October were recalculated.

Dose calculations and Rad Monitor Setpoints for the period were also recalculated.

The event was reviewed with chemistry personnel.

A standard will now be run with each silica gel analysis sample set, and reviewed by chemistry management to aid in flagging this type of event, as promptly as possible.

Significance: The silica gel analysis data for May to October was recalculated, based on a correct efficiency value. All release files for this period were revised appropriately. It was determined that the numbers generated were well within historical values and did not impose upon the health and safety of the public.

Discharge Piping Volume Discrenency Between the ODCM and liquid Waste Tank Release Procedures Several years ago the liquid discharge piping was extended the length of the discharge canal. Should the discharge of a Radioactive Waste Tank be of sufficient activity, the allowable release rate could be limited, to preclude exceeding Maximum Permissible Concentration (MPC). Due to the large volume of the discharge piping the higher activity tank water could remain in the discharge piping. Subsequent releases could potentially push the original, higher activity water out of the discharge piping at a rate, which could exceed the allowable discharge rate and exceed MPCs.

Procedural controls were written into the ODCM and the specific Radioactive Waste Tank release procedures, to flush the volume of the discharge piping, following the release of a higher activity tank, which could conceivably cause the situation described. The flush volume is based on calculations of the volume of the discharge piping performed at the time the discharge piping was installed.

The volume stated in the ODCM did not agree with the volume stated in the various Radioactive Waste Tank release procedures. The ODCM stated a number of 15,500 gallons and the Radioactive Waste Tank release procedures state a volume of 15,000 gallons.

There existed an apparent potential for an insufficient flush to create a situation in which MPC limits could have been exceeded.

Cause: The cause was determined to be a typographical error on the Radioactive Waste Tank procedures, which went undetected.

Corrective The event was documented and assessed by Chemistry Management, through the Actions: Condition Reporting System, Condition Report number 20014698.

Calculations were performed to verify the discharge piping volume. It was determined that the number of 15,500 gallons would remain in the ODCM. It was determined that the Radioactive Waste Tank procedures would be revised to use a conservative number of 17,000 gallons.

Procedural controls, requiring flushing, were implemented in 1991. An assessment of all waste tank releases since 1991 was performed. It was determined that there was no instance of insufficient flush which could have potentially caused the exceeding of MPC limits.

Significance: The assessment of Radioactive Waste Tank releases concluded that there was no instance in which MPC limits were exceeded. This event did not impose upon the health and safety of the public.

Unmonitored Release Path Identified In the early 1980s' the Unit 1 and Unit 2 Air Ejector Exhaust was redirected from discharge directly to the environment to the Auxiliary Building Normal Ventilation System, via galvanized exhaust ductwork. The ductwork included a number of exhaust duct drains, located at low points, to prevent condensed moisture from entering the Auxiliary Building Ventilation System.

Various Turbine Building drains are directed to the Turbine Building Sump. The Turbine Building Sump is a monitored release path. In 2001, it was identified that the Unit 1 Air Ejector Exhaust duct drain effluent entered the DI water supply head tank overflow funnel, which directed it to the cooling water header. This is an unmonitored release path.

Cause: It is believed that the original modification directed the drain effluent to the Turbine Building Sump. This is borne out by the fact that the Unit 2 Air Ejector Exhaust duct drain, which was modified at the same time as Unit 1, is directed to the Turbine Building Sump. At some undetermined time, the piping was changed in association with a change to the DI water supply head tank overflow drain.

This was due to a lack of understanding, on the part of the parties performing this change.

Corrective This event was documented and assessed by Chemistry Management through the Actions: Condition Reporting System, Condition Report number 200187224.

This event was reviewed with chemistry personnel.

The drain effluent was redirected and is now being collected.

An evaluation of the impact of this event determined the following:

There were no significant Primary to Secondary leaks during this period.

No water has collected over the first 3 months of collection.

There has always been radiation monitors, continuously monitoring Air Ejector Discharge prior to entering the exhaust ductwork.

The most significant release monitored by the Air Ejector Radiation Monitor would have been insignificant compared to any detectable release in normal ventilation.

Isotopes, present in the condensed Air Ejector Exhaust, would predominately be radiogases. Radiogas isotopes in liquid releases do not contribute to offsite dose.

Significance: It is concluded that this event did not impose upon the health and safety of the public.

Attachment 4 PRAIRIE ISLAND NUCLEAR GENERATING PLANT Nuclear Management Company, LLC Summary of Changes to the Offsite Dose Calculation Manual and Revision 16 of the Offsite Dose Calculation Manual Anneff2001.doc

SUMMARY

OF CHANGES TO OFFSITE DOSE CALCULATION MANUAL REV 16 The Offsite Dose Calculations Manual ,ODCM, was revised to correct two Tech Spec reference that have been detected since the last revision. These references are wrong as a result of a revision to the Technical Specifications.

Those items are as follows:

1) ODCM section 2.5 incorrectly referenced Technical Specification T.S.6.5.H.6. The reference was changed to T.S.6.5.D.6.

2) ODCM section 2.7 incorrectly referenced Technical Specification T.S.6.5.H.I. The reference was changed to T.S.6.5.D.l.

An evaluation of the above listed changes resulted in the determination that the changes maintain the levels of radioactive effluent control required by 10 CFR 20.1301(a), 10 CFR 50.36a, 10 CFR 50, Appendix A (GDC 60 & 64) and Appendix I, 40 CFR 190, and do not adversely impact the accuracy or reliability of effluent dose or setpoint calculations at Prairie Island.

UOFFSITE DOSE CALCULATION H4 II MANUAL (ODCM) REV: 16 Page9 of 219 OFFSITE DOSE CALCULATIONS MANUAL INTRODUCTION The Offsite Dose Calculation Manual (ODCM) describes the methodologies and parameters used in: 1) the calculation of offsite doses resulting from radioactive gaseous and liquid effluents; 2) the calculation of gaseous and liquid effluent monitoring instrumentation Alarm/Trip Setpoints. The methodology stated in this manual is acceptable for use in demonstrating compliance with 10CFR 20.1301 (a)(1),

10CFR 50.36A, 10CFR 50, Appendix A (GDC 60 & 64) and Appendix I, and 40 CFR 190.

The ODCM is based on "Radiological Effluent Technical Specification of PWR's (NUREG-0472, October 1978)", "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants (NUREG-0133, October 1978)", and "Offsite Dose Calculation Manual Guidance (NUREG-1301, April 1991). Specific plant procedures for implementation of this manual are provided in the Count Room Manual, (Radiation Protection Implementing Procedures 4000 Series).

Also included in this manual is information related to the RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM (REMP). Tables 7.1, 7.2 and 7.3 designate specific sample types, reporting levels and lower limits of detection currently used to satisfy the sampling requirements for the REMP.

Licensee initiated changes to the ODCM:

1. SHALL be documented and records of reviews performed shall contain:

a. Sufficient information to support the change(s) together with the appropriate analyses or evaluations justifying the change(s).

b. A determination that the change(s) maintain the level of radioactive effluent control required by 10CFR20.1301 (a)(1), 10CFR50.36A, 40CFR1 90, 10CFR50, Appendix I, and not adversely impact the accuracy or reliability of effluent, dose or setpoint calculations.

2. SHALL become effective upon review and acceptance by the Operations Committee.

3. SHALL be submitted to the NRC in the form of a complete legible copy of the entire ODCM as a part of or concurrent with the Annual Radioactive Effluent Report for the period of the report in which the change in the ODCM was made. Each change SHALL be identified by markings in the margin of the affected pages clearly indicating the area of the page that was changed. The date (i.e., month and year) of the change SHALL be clearly indicated on the "Record of Revision" page.

Since Fe-55, Sr-89, Sr-90, and alpha concentrations are determined from composite samples, the liquid monitor setpoint determinations should be completed using the most recent available composite sample results.

Monitor high alarm or isolation setpoints will be established by one of the following:

a. Monthly calculation of setpoints using the methodology of Sections 4.1.1 and 4.1.3.

b. Calculation of alarm setpoint based on analysis prior to discharge using methodology of Section 4.1.2.

c. Alarm setpoint determined using methodology of Section 4.1.1 and 4.1.3 assuming all radionuclides have an MPC of 1E-7 jiCi/ml. No recalculation of setpoints is necessary unless an increase in alarm setpoint is desired.

PWR GALE Code source terms (Table 4.1) may be used if there were no detectable isotopes in the previous month or in the analysis prior to release. If the newly calculated setpoint is less than the existing monitor setpoint, the setpoint SHALL be reduced to the new value. If the calculated setpoint is greater than the existing setpoint, the setpoint may remain at the lower value or increase to the new value.

D. The monitor high alarm setpoint above background (ncpm) SHALL be set at or below the C.R. value.

4.1.4 Monitor Calibration Liquid effluent monitors are calibrated periodically using a Cs-137 standard. Since the actual isotopic mixes of the liquids released may contain nuclides with different gamma energies and yields than the calibration standard, the response of the monitor varies with respect to the actual energies and abundances of the nuclides in the mix being monitored when compared to Cs-137.

Effluent release computer calculations that compute setpoint determinations or expected monitor readings during or prior to a release compensate for the difference in gamma energies and yields and adjust the monitor setpoint or predicted monitor reading according to the actual nuclide mix. The assumption is made that the monitor's response is directly proportional to the gamma energies.

The cumulative errors associated with the monitor calibration methodology are not accounted for in the determination of the individual monitor setpoints. There is sufficient conservatism built into the selection of the actual monitor setpoint; plus the fact that the monitor fractions used in the setpoint determination equation determine that it would be necessary for all of the effluent monitors to be in alarm before the limits of 10CFR Part 20 would be exceeded.

For CONTINUOUS RELEASES, the alarm trip setpoints discussed in Section 4.1 will assure that these concentrations are not exceeded. For BATCH RELEASES, concentrations of radioactivity in effluents prior to dilution will be determined, providing protection in addition to the alarm trip setpoint discussed in Section 4.1. Concentration in diluted effluents will be calculated using these results.

4.2.1 Continuous Releases Continuous liquid releases can occur from PINGP through steam generator blowdown. The alarm trip setpoints discussed in Section 4.1 will assure that releases from this pathway will not exceed the limits of 10CFR20.

Other minor releases of a continuous nature have occurred at PINGP through the turbine building sump system. These releases were minor and are not expected to occur in the future. However, a continuous composite sample will be maintained at the discharge from the turbine building sump with samples being taken and analyzed weekly. If these samples indicate-detectable levels of radionuclides, the methodologies given in Section 4.2.2 will be applied to the turbine sump weekly releases and the limit in Equation 4.2-2 will be lowered to account for this source term. Doses from radionuclides contained in turbine building sump effluent diverted to the landlocked area are adequately accounted for since the calculations conservatively assume all the activity is dischargd to the river per Section 4.2.2.

OFFSITE DOSE CALCULATION H4 MANUAL (ODCM) REV: 16 Page 40 of 219 4.2.2 Batch Releases To further show compliance with 10CFR20, the radioactivity content of each BATCH RELEASE will be determined prior to release. The concentration of the various radionuclides in the BATCH RELEASE prior to dilution, is divided by the minimum dilution flow to obtain the concentration at the UNRESTRICTED AREA. This calculation is shown in the following equation:

Conci = C9 R (4.2-1)

MDF where Conci = concentration of radionuclide i at the site boundary, j.Ci/ml; Ci = concentration of radionuclide i in the potential batch release, pCi/ml; R = release rate of the batch MDF = minimum dilution flow (=67,300 gpm)

The flush rate SHALL NOT exceed the maximum discharge flow rate and may be accomplished with water from other release paths. If more than one waste batch tank requiring flushing are to be released, the discharge pipe may be flushed following the final tank release.

Volume of discharge pipe = 15,500 gal.

4.3 Liquid Effluent Dose - Compliance with 10CFR50 Doses resulting from liquid effluents will be calculated monthly to show compliance with 10CFR50. A cumulative summation of total body and organ doses for each calendar quarter and calender year will be maintained as well as projected doses for the next month.

Since Fe-55, Sr-89, Sr-90, and alpha concentrations are determined from composite samples, the monthly liquid effluent dose calculations and comparisons to quarterly and annual limits should be completed using the most recent available composite sample results. The quarterly and annual dose calculations SHALL be completed using the actual composite sample results.

The limits of 10CFR50 are on a per reactor unit basis. The liquid radwaste system at PINGP is shared by both reactor units making it impossible to separate the releases of the two units. The releases that can be separated by unit, steam generator blowdown and turbine building sump releases, contribute a very small portion of the total liquid releases from PINGP. Therefore, for compliance with 10CFR50 the releases from both units will be summed and the limits of Appendix I will be doubled.

4.3.1 Determination of Liquid Effluent Dilution To determine doses from liquid effluents the near field average dilution factor for the period of release must be calculated. This dilution factor must be calculated for each BATCH RELEASE and each CONTINUOUS RELEASE mode. The dilution factor is determined by:

Fk = R (4.3-1)

X ADFk

MANUAL (ODCM) REV: 16 Page 42 of 219 where:

Rk = release rate of the batch or continuous release during the period, k, gpm.

ADFk =average dilution flow during the time period of release k, gpm.

The value of X is the site specific factor for the mixing effect of the PINGP discharge structure. This value is 10 for PINGP while operating in the closed cycle cooling mode. The product of X and ADFk is limited to 1000 cfs (4.5 x 105 gpm). Therefore, since blowdown flow in closed cycle is 150 cfs, the denominator of Equation 4.3-1 is always 4.5 x 10 5 in closed cycle. In once through or helper mode, the value if X is reduced to 1.0.

4.3.2 Dose Calculations The dose contribution from the release of liquid effluents will be calculated monthly. The dose contribution will be calculated using the following:

where:

D. = Xk Yi Ai~tk Cik Fk (4.3-2) where:

DT = the dose commitment to the total body or any organ T, from the liquid effluents for the period of release, mrem; Cik = the average concentration of radionuclide, i, in undiluted liquid effluent for liquid release k, 0Ci/ml; Ai, = the site related ingestion dose commitment factor to the total body or any organ -i for each identified principal gamma and beta emitter, mrem/hr per j.Ci/ml; Fk = the near field average dilution factor for Cik during liquid effluent release k, tk = the duration of release k, hours.

A table of Ai~values for an adult at the PINGP are presented in Table 4.2.

Mississippi River water is not used as a potable water supply within 300 miles downstream of the PINGP. Wells are used for irrigation downstream of the plant.

4.3.3 Cumulation of Doses Doses calculated monthly will be summed for comparison with quarterly and annual limits. The monthly results should be added to the doses cumulated from the other months in the quarter of interest and in the year of interest for the combined releases of both reactor units and compared to the limits given in Section 2.3.

The quarterly limits represent one half of the annual design objective. If these quarterly or annual limits are exceeded, a special report should be submitted to the USNRC identifying the cause and corrective action to be taken. If twice the quarterly or annual limits are exceeded, a special report SHALL be submitted showing compliance with 40CFR190.

REV: 16 Page 44 of 219 4.3.4 Proiection of Doses Anticipated doses resulting from the release of liquid effluents will be projected monthly. If the projected doses for the month exceed 2 percent of the limit specified in Section 2.3.b, additional components of the liquid radwaste treatment system will be used to process waste. The projected doses will be calculated using Equation 4.3-2. The dilution factor, Fk, will be calculated by replacing the term ADFk in Equation 4.3-1 with the term MDF from Equation 4.2-1. The total source term utilized for the most recent dose calculation should be used for the projections unless information exists indicating that actual releases could differ significantly in the next month. In this case, the source term would be adjusted to reflect this information and the justification for the adjustment noted. This adjustment should account for any radwaste equipment which was operated during the previous month that could be out of service in the coming month.

Monitor high alarm or isolation setpoints will be established in one of the following ways:

a. Monthly calculation of setpoint using the methodology of Section 5.1.1 for CONTINUOUS RELEASES using previous month releases as source term.

b. Prior to each containment PURGE, recalculation of the setpoint using the methodology of Section 5.1.1 based on the sample taken prior to PURGING.

c. In lieu of (5.1.a) and (5.1.b) above, alarm setpoints may be established using the methodology of Section 5.1.1 using conservative assumptions (e.g., 100%

PWR GALE Code source terms (Table 5.2) may be used if there were no detectable isotopes in the previous month or in the analysis prior to PURGING. Ifthe newly calculated setpoint is less than the existing monitor setpoint, the setpoint SHALL be reduced to the new value.

MANUAL (ODCM)" REV: 16 Page 48 of 219 5.1.2 Air Ejector Monitors Radiation monitors 1 R-1 5 and 2R-1 5 provide an indication of gross noble gas activity at the main condenser air ejector of Unit 1 and Unit 2, respectively. These monitors are provided to give rapid indication of steam generator tube leakage. They are not effluent monitors since the air ejectors are vented to the auxiliary building vents during normal plant operation and releases are monitored by the auxiliary building vent monitoring system.

5.1.3 Monitor Calibration Gaseous effluent monitors are calibrated periodically using available gas mixes existing in plant systems. Since the available gas mixes vary in isotopic ratios and the energies of those isotopes span a range of energies, more than one gas mix is used during the calibration. One mix is predominantly Xe-133 with lower level beta and gamma energies and a second mix which contains a larger variety of longer lived plant gases that more accurately represent the higher beta energy range. The result of this method of calibration is two separate calibration curves for each monitor.

One curve to be used when the isotopic mix being monitored is primarily Xe-1 33 and the other curve is for use when the mix is unknown or is known to contain a mixture of other fission and activation gases.

Effluent release computer calculations that compute setpoint determinations or expected monitor readings during or prior to a release utilize the correct calibration curves and adjust the monitor setpoint or predicted monitor reading according to the actual nuclide mix.

The cumulative errors associated with the monitor calibration methodology are not accounted for in the determination of the individual monitor setpoints. There is sufficient conservatism built into the selection of the actual monitor setpoint; plus the fact that the monitor fractions used in the setpoint determination equation determine that it would be necessary for all the effluent monitors to be in alarm before the limits of 10CFR Part 20 would be exceeded.

The limits of 10CFR20 must be met on an instantaneous basis at the hypothetical worst case location, and apply on a per site basis.

a. Shield building effluent particulates and iodines are filtered through a PAC (Particulate Absolute Charcoal) system and the auxiliary building vent normal ventilation has no filtration.

b. The lower limit of detection limits specified in Table 3.1 can not be obtained on all the specified nuclides with normal sample flow and a sample duration of less than 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

c. Shield building vent releases are monitored via a noble gas monitor.

d. Auxiliary building normal ventilation flow is higher than the special ventilation fans that vent via the shield building vent stack.

Therefore, it is conservative to assume that the auxiliary building normal ventilation system would continue to run during the testing/maintenance period. The surveillance test or maintenance/work being performed should be evaluated to ensure the airborne activity in the affected areas will not increase during the evolution. If this evaluation indicates a possible increase in airborne effluents, or radiation monitors or continuous air monitors in the affected buildings indicate higher than normal background airborne activity before the evolution begins, the shield building vent stack sample SHALL be sampled and analyzed as described in Table 3.1.

Since Sr-89 and Sr-90 concentrations are determined from composite samples, the pre-release, weekly and monthly airborne dose calculations and comparisons to quarterly and annual limits should be completed using the most recent available composite sample results. The quarterly dose values and critical receptors reported to the USNRC SHALL be calculated using the actual composite results.

5.2.1 Noble Gases To comply with the 10CFR20 dose limit of 100 mrem TEDE to MEMBERS OF THE PUBLIC, the dose rate at the SITE BOUNDARY resulting from noble gas effluents is limited to 500 mrem/yr to the total body and 3000 mrem/yr to the skin. The setpoint determinations discussed in the previous section are based on the dose calculational method presented in NUREG-0133. They represent a backward solution to the limiting dose equations in NUREG-01 33. Setting alarm set trip points in this manner will assure that the limits of 10CFR20 are met for noble gas releases.

Therefore, no routine dose calculations for noble gases will be needed to show compliance with this part. Routine calculations will be made for doses from noble gas releases to show compliance with 10CFR50, Appendix I as discussed in Section 5.3.1.

5.2.2 Radioiodine, Radioactive Particulates, and Other Radionuclides For compliance with 1 OCFR20, the dose rate at the SITE BOUNDARY resulting from the release of radioiodines and particulates with half lives greater than 8 days is limited to 1500 mrem/yr to any organ. Calculations showing compliance with this dose rate limit will be performed for BATCH RELEASES prior to the release and weekly for all releases. To show compliance, Equations 5.2-1 will be evaluated for 1-131, 1-133, tritium, and radioactive particulates with half-lives greater than eight days.

For showing compliance with 10CFR20, calculations based on Equation 5.2-1 will be made once per week. The source terms (Qiv) will be determined from the results of analysis of vent particulate filters and charcoal canisters and vent flow rate. These source terms include all gaseous releases from PINGP.

Significant short-term BATCH RELEASES of long-lived radioactive particulates and tritium will result from containment PURGES. Calculations will be made for these releases separately to further assure compliance with 10CFR Part 20 prior to release. These calculations will be used only to determine whether or not the PURGE release will be allowed to occur.

Source terms will be determined from the results of isotopic analyses of samples from containment prior to release. Equation 5.2.1 will be used in conjunction with the following relationship to demonstrate that the BATCH RELEASE does not exceed the dose rate limit:

BL = 1500- (Dv- DO) (5.2-2) where:

BL = limiting dose rate for the batch, mrem/yr; Dv = previous week's dose rate from all continuous and batch releases mrem/yr; p = previous week's dose rate from all PURGE releases mrem/yr.

Page 52 of 219 5.3 Gaseous Effluents - Compliance with 10CFR50 Doses resulting from the release of noble gases, radioiodines and particulates must be calculated to show compliance with Appendix I of 10CFR50. The calculations will be performed monthly for all gaseous effluents.

The limits of 10CFR50 are on a per reactor unit basis. The GASEOUS RADWASTE TREATMENT SYSTEM and the auxiliary building at PINGP is shared by both reactor units making it impossible to separate the releases of the two units.

The releases that can be separated by unit contribute a very small portion of the total gaseous releases form PINGP. Therefore, for compliance with 10CFR50 the releases from both units will be summed and the limits of Appendix I will be doubled.

Releases made via the shield building vents as a result of routine surveillance tests or scheduled short term maintenance/work activities of 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months or less do not require the sampling and analysis of shield building vent stack samples described in Table 3.1 for the following reasons:

a. Shield building effluent particulates and iodines are filtered through a PAC (Particulate Absolute Charcoal) system and the auxiliary building vent normal ventilation has no filtration.

b. The lower limit of detection limits specified in Table 3.1 can not be obtained on all the specified nuclides with normal sample flow and a sample duration of less than 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

c. Shield building vent releases are monitored via noble gas monitor.

d. Auxiliary building normal ventilation flow is higher than the special ventilation fans that vent via the shield building vent stack.

Therefore, it is conservative to assume that the auxiliary building normal ventilation system would continue to run during the testing/maintenance period. The surveillance test or maintenance/work being performed should be evaluated to ensure the airborne activity in the affected areas will not increase during the evolution. If this evaluation indicates a possible increase in airborne effluents, or radiation monitors or continuous air monitors in the affected buildings indicate higher than normal background airborne activity before the evolution begins, the shield building vent stack sampled SHALL be sampled and analyzed as described in Table 3.1.

" REV: 16 7 Page 69 of 219 BASES 2.0 LIQUID EFFLUENTS 2.1/2.2 CONCENTRATION This control is provided to ensure that the concentration of radioactive materials released in liquid waste effluents from the site to UNRESTRICTED AREAS will be less than the concentration levels specified in 10CFR20, Appendix B, Table II,Column 2. This limitation provides additional assurance that the levels of radioactive materials in bodies of water outside the site will not result in exposures exceeding (1) the Section II.A design objectives of Appendix I, 10CFR Part 50, and (2) the limits of 10CFR Part 20.1301(a)(1).

The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radioisotope and its MPC in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication 2.

This control applies to the releases of radioactive materials in liquid effluents from all units at the site.

Secondary condenser drains were not included in the routine sampling requirements of Table 2.1. Operating experience has shown that the condenser activity during plant transients normally consists of very low levels of tritium. Condensers are normally only released directly to the environment during plant startups and shutdowns and these volumes combined with the low levels of activity are insignificant when compared to the waste tank activities. Condenser releases should be sampled and analyzed during a significant plant event (i.e. steam generator tube rupture, or steam dump to the condenser with a primary to secondary leak >725 gpd).

2.3/2.4 DOSE Provided to implement the requirements of Sections II.A, III.A and IV.A of Appendix I, 10CFR Part 50. The Limiting Condition for Operation implements the guides set forth in Section II.A of Appendix I. The ACTION statements provide operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents will be kept "as low as is reasonably achievable". Considering that the nearest drinking water supply using the river for drinking water is more than 300 miles downstream, there is reasonable assurance that the operation of the facility will not result in radioactive concentrations in the drinking water that are in excess of the 40CFR141 requirements.

The requirements that appropriate portions of this system be used when specified provides assurance that the releases of radioactive materials in liquid effluents be kept "as low as reasonably achievable". This control implements the requirements of 10CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10CFR Part 50 and the design objective given in Section II.D of Appendix I to 10CFR Part 50. The limits governing the use of appropriate portions of the liquid radwaste system were specified as a suitable fraction of the guide set forth in Section II.A of Appendix I, 10CFR Part 50, for liquid effluents.

The liquid radwaste treatment system is shared by both units. It is not practical to determine the contribution from each unit to liquid radwaste releases. For this reason, liquid radwaste releases will be allocated equally to each unit.

The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 of Appendix A to 10CFR Part 50.

2.9/2.10 LIQUID STORAGE TANKS Restricting the quantities of radioactive material contained in the specified tanks provides assurance that in the event of an uncontrolled release of the contents of the tank, the resulting concentrations would be less than the limits of 10CFR Part 20, Appendix B, Table II, Column 2, in an UNRESTRICTED AREA.

____ ____ Page 71 of 219 3.0 GASEOUS EFFLUENTS 3.1/3.2 DOSE RATE This control is provided to ensure that the dose rate at any time at the SITE BOUNDARY from gaseous effluents from all units on the site will be within the annual dose limits of 10CFR Part 20 for UNRESTRICTED AREAS. The annual dose limits are the doses associated with the concentrations of 1 OCFR 20, Appendix B, Table II, Column 1. These limits provide reasonable assurance that the radioactive material discharged in gaseous effluents will not result in the exposure of an individual in an UNRESTRICTED AREA to annual average concentrations exceeding limits specified in Appendix B, Table II of 10CFR Part 20. For individuals who may at times be within the SITE BOUNDARY, the occupancy of the individual will be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the SITE BOUNDARY. The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to an individual at or beyond the SITE BOUNDARY to less than or equal to 500 mrem/year to the total body or to less than or equal to 3000 mrem/year to the skin. These release rate limits also restrict, at all times, the corresponding thyroid dose rate above background to less than or equal to 1500 mrem/year at or beyond the SITE BOUNDARY.

This control applies to the release of radioactive materials in gaseous effluent from all units at the site.

3.3/3.4 DOSE FROM NOBLE GAS This control is provided to implement the requirements of Sections ll.B, III.A and IV.A of Appendix I, 10CFR Part 50. The Limiting Conditions for Operation implement the guides set forth in Section II.B of Appendix I. The ACTION statement provides the required operating flexibility and at the same time implements the guides set forth in Section IV.A of Appendix I to assure that the release of radioactive material in gaseous effluents will be kept "as low as reasonably achievable".

The Limiting Conditions for Operation are the guides set forth in Section II.C of Appendix I.

The ACTIONS statement provides the required operating flexibility and at the same time implements the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive materials in gaseous effluents will be kept "as low as reasonable achievable".

The release rate specifications for 1-131, 1-133, tritium and radioactive particulates with half-lives greater than eight days are dependent on the existing radionuclide pathways to MEMBERS OF THE PUBLIC in the UNRESTRICTED AREA, using child dose conversion factors. The pathways which are examined in the development of these calculations are:

1) individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, 3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man, and 4) deposition on the ground with subsequent exposure of man.

3.7/3.8 GASEOUS RADWASTE TREATMENT SYSTEMS This control provides assurance that the Waste Gas Treatment System and the VENTILATION EXHAUST TREATMENT SYSTEMS will be available for use whenever gaseous wastes are released to the environment. The requirement that the appropriate portions of the Waste Gas Treatment System be used when specified provides reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept "as low as reasonably achievable". This specification implements the requirements of 10CFR 50.36a, General Design Criterion 60 of Appendix A to 10CFR Part 50, and the design objective given in Section II.D of Appendix I to 10CFR Part 50. The specified limits governing the use of appropriate portions of the systems were specified as a suitable fraction of the guide set forth in Sections II.B and II.C of Appendix I, 10CFR Part 50, for gaseous effluents.

The Waste Gas Treatment System, containment purge release vent, and spent fuel pool are shared by both units. Experience has also shown that contributions from both units are released from each auxiliary building vent. For these reasons, it is not practical to allocate releases to a specific unit. All releases will be allocated equally in determining conformance to the design objectives of 10CFR Part 50, Appendix I.

Restricting the quantities of radioactivity which can be stored in one decay tank provides assurance that in the event of an uncontrolled release of the tank's contents, the resulting total body exposure to an individual at the nearest EXCLUSION AREA BOUNDARY will not exceed 0.5 rem.

__________________i**!lF Page 73 of 219 The cooling towers at Prairie Island are located to the south of the plant and are within 500 to 2000 feet from the point of release. At low wind velocities (below 10 mph) the gaseous activity released from the gaseous radwaste system could be at or near ground level near the cooling towers and remain long enough to be drawn into the circulating water in the tower. This control minimizes the possibility of releases of gaseous effluents from entering the river from cooling tower scrubbing.

3.9/3.10 EXPLOSIVE GAS MONITORING INSTRUMENTATION To ensure the concentration of potentially explosive gas mixtures contained in the waste gas treatment system is maintained below the flammability limits of hydrogen and oxygen.

Automatic control features are included in the system to prevent the hydrogen and oxygen concentrations from reaching these flammability limits. Maintaining the concentrations below the flammability limit provides assurance that the releases of radioactive materials will be controlled in conformance with the requirements of General Design Criterion 60 of Appendix A to 1 OCFR Part 50.

The waste gas treatment system is a pressurized system with two potential sources of oxygen: 1) oxygen added for recombiner operation, and 2) placing tanks vented for maintenance back on the system. The system is operated with flow through the recombiners and with excess hydrogen in the system. By verifying that oxygen is less than or equal to 2% at the recombiner outlet, there will be no explosive mixtures in the system. Waste gas system oxygen is monitored by the two recombiner oxygen analyzers and the 121 gas analyzer. The 121 gas analyzer only monitors the low level loop of the waste gas system. If the required gas analyzers are not operable, the oxygen to the recombiner will be isolated to prevent oxygen from entering the system from this source.

Tanks that may undergo maintenance are normally purged with nitrogen before placing them in service to eliminate this as a source of oxygen.

3.11/3.12 RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION The radioactive gaseous effluent monitoring instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous effluents during actual or potential releases of gaseous effluents. The Alarm/Trip Setpoint for these instruments SHALL be calculated and adjusted in accordance with the methodologies and parameters in the ODCM to ensure that the alarm/trip will occur prior to exceeding the limits of 10CFR Part 20.

Page 74 of 219 6.0 TOTAL DOSE This control is provided to meet the dose limitations of 10CFR Part 190 that have been incorporated into 10CFR 20 by FR 18525. The control requires the preparation and submittal of a Special Report whenever the calculated doses due to releases of radioactivity and to radiation from uranium fuel cycle sources exceed 25 mrems to the whole body or to any organ, except the thyroid, which SHALL be limited to less than or equal to 75 mrems. For sites containing up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40CFR Part 190 if the individual reactors remain within twice the dose design objectives of Appendix I, and if direct radiation doses from the units (including outside storage tanks, etc.) are kept small. The Special Report will describe a course of action that should result in the limitation of the annual dose to a MEMBER OF THE PUBLIC to within 40CFR Part 190 limits. For the purposes of the Special Report, it may be assumed that the dose commitment to the MEMBER OF THE PUBLIC from other uranium fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 8 km must be considered. If the dose to any MEMBER OF THE PUBLIC is estimated to exceed the requirements of 40CFR Part 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40CFR Part 190 have not already been corrected), in accordance with the provisions of 40CFR 190.11 & 10CFR 20.405c, is considered to be a timely request and fulfills the requirements of 40CFR Part 190 until NRC staff action is completed. The variance only relates to the limits of 40CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10CFR Part 20, as addressed in Specification 2.1 and 3.1. An individual is not considered a MEMBER OF THE PUBLIC during any period in which he/she is engaged in carrying out any operation that is part of the nuclear fuel cycle.

7.0 RADIOLOGICAL ENVIRONMENTAL MONITORING 7.1/7.2 MONITORING PROGRAM Provides measurements of radiation and radioactive materials in those exposure pathways and for those radionuclides which lead to the highest potential radiation exposures of individuals resulting from the plant operation. This program thereby supplements the radiological effluent monitoring by verifying that the measurable concentrations of radioactive materials and levels are not higher than expected in the bases of the effluent measurements and modeling of the environmental exposure pathways.

The detection capabilities required by Table 7.1 are state-of-the art for routine environmental measurements in industrial laboratories and the LLDs for drinking water meet the requirement of 40CFR Part 141. )

The best survey information from door-to-door, aerial or consulting with local agricultural authorities SHALL be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 1 OCFR Part 50. Restricting the census to gardens of greater than 500 square feet provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/year) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were used: 1) that 20% of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and 2) a vegetation yield of 2 kg/square meter.

7.5/7.6 INTERLABORATORY COMPARISON PROGRAM The requirement for participation in an interlaboratory comparison program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive material in environmental sample matrices are performed as part of a quality assurance program for environmental monitoring in order to demonstrate that the results are reasonably valid.

b. A composite sample is one in which the quantity of liquid sampled is proportional to the quantity of liquid waste discharge and in which the method of sampling employed results in a specimen which is representative of the liquids released.

c. The principal gamma emitters for which the LLD specification will apply are exclusively the following radionuclides: Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, Ce-141, and Ce-144. This list does not mean that only the nuclides are to be detected and reported. Other peaks which are measurable and identifiable, together with the above nuclides, SHALL also be identified and reported.

d. Nuclides which are below the LLD for the analyses should not be reported as being present at the LLD level. When unusual circumstances result in LLDs higher than required, the reasons SHALL be documented in the Annual Radioactive Effluent Report.

e. A CONTINUOUS RELEASE is the discharge of liquid wastes of a non-discrete volume; e.g., from a volume of system that has an input flow during the continuous release.

f. To be representative of the quantities and concentrations of radioactive materials in liquid effluents, samples SHALL be collected continuously in proportion to the rate of flow of the effluent stream. Prior to analyses, all samples taken for the composite SHALL be thoroughly mixed in order for the composite sample to be representative of the effluent release.

g. A BATCH RELEASE is the discharge of liquid wastes of a discrete volume. Prior to sampling for analyses, each batch SHALL be isolated, and then thoroughly mixed to assure representative sampling.

h. Daily grab samples from the turbine building sumps SHALL be collected and analyzed for principal gamma emitters, including 1-131, whenever primary to secondary leakage exceeds 150 gpd in any steam generator. This sampling is provided in lieu of continuous monitoring with automatic isolation.

A continuous sample is one in which the sampling media is in place at all times during the release period, with the exception of periods necessary to change sampling media and scheduled short term equipment maintenance. If the sample media is not in place during the entire release period, an explanation of the occurrence, actions taken to restore the sampler and to prevent recurrence, and a summary description to explain the occurrence's effect on the analysis validity SHALL be included in the Annual Radioactive Effluent Report.

k. Continuous samples of the Turbine Building Sumps are collected via on-line composite samplers. These samplers function on timers and collect a predetermined volume of effluent whenever the TBS pumps are in operation. Samples from these compositors are collected daily and saved for the preparation of a weekly composite prepared utilizing volumes proportional to the sample volumes collected daily by the compositor.

If the use of a submersible pump is necessary to maintain sump level, that pump should be positioned above the normal TBS pump controlling level and include a timer to allow the calculation of the additional release volume.

With >1 piCi/gm DOSE EQUIVALENT 1-131 in either Unit 1 or Unit 2 reactor coolant system, the iodine and particulate collection devices for all release points SHALL be removed and analyzed daily until it is shown that a pattern exists which can be used to predict the release rate. Sampling may then revert to weekly. When samples collected for one day are analyzed, the corresponding LLD's may be increased by a factor of 10.

Samples SHALL be analyzed within 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months after removal.

d. To be representative of the average quantities and concentrations of radioactive materials in particulate form in gaseous effluents, samples should be collected in proportion to the rate of flow of the effluent streams.

e. The principal gamma emitters for which the LLD control applies include the following radionuclides: Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135, and Xe-138 for noble gas analysis and Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, Ce-141, and Ce-144 in iodine and particulate analysis. This list does not mean that only these nuclides are to be considered. Other gamma peaks that are identifiable, together with those of the above nuclides, SHALL also be detected and reported.

f. Nuclides which are below the LLD for analyses should not be reported as being present at the LLD level for that nuclide. When unusual circumstances result in LLD's higher than reported, the reasons SHALL be documented in the Annual Radioactive Effluent Report.

g. For continuous samples, the ratio of the sample flow rate to the samples stream flow rate SHALL be known for the time period sampled (Conservative assumptions may be used). Design flow rates may be used for building exhaust vent flow rates.

h. A continuous sample is one in which the sampling media is in place at all times during the release period, with the exception of periods necessary to change sampling media and scheduled short term equipment maintenance of two hours or less. If the sample media is not in place during the entire release period (except as described above), an explanation of the occurrence, actions taken to restore the sampler and to prevent reoccurrence, and a summary description to explain the occurrence's effect on the analysis validity SHALL be included in the Annual Radioactive Effluent Report.

L Releases are made via the shield building vents only during PURGING, or operation of special ventilation systems. When ventilation fans in any vent path are not in service for the entire sample period, in lieu of weekly removal and analysis of iodine and particulate collection devices, these devices may be removed and analyzed following each release provided that the release lasts less than one week. Releases made via the plant ventilation paths as a result of routine surveillance tests, operational testing or scheduled short term maintenance activities of 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months or less do not require special sampling and analysis provided that plant conditions do not indicate the completion of these activities would cause an increase in the release of activity. Removal and analysis of collection devices is not required if releases are not being made.

j. Grab samples for atmospheric steam releases are representative liquid grab samples from the respective steam generator.

k. Atmospheric steam releases are the timed releases of steam from the steam generators to the atmosphere via either the power operated reliefs, steam dump valves or flash tank vents. It does not include steam dumped via the condenser.

1. A composite sample is one in which the quantity of liquid sampled is proportional to the quantity of steam released and in which the method of sampling employed results in a specimen which is representative of the total steam released form the respective steam generator.

m. Containment Purges includes PURGE releases with either the Inservice Purge or Containment Purge Fans and also VENTING of containment utilizing the Post Loca Vent System. When the release is completed via the Post Loca Vent, the pre-release tritium, particulate and charcoal samples should be used for all analyses, and continuous samples collected during the release are not required. During Cold Shutdown periods, the availability of ventilation systems and the position of containment air-lock doors may require that portions of the required samples be collected with installed continuous monitors or portable sampling equipment.

Appendix B - Concentrations in Air and Water Above Natural Background

[See footnotes at end of Appendix B]

Element (atomic number)

Any single radionuclide not listed above with decay mode other than alpha emission or spontaneous fission and with radioactive half-life less than 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

Any single radionuclide not listed above with decay mode other than alpha emission or spontaneous fission and with radioactive half-life greater than 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

Any single radionuclide not listed above, which decays by alpha emission or spontaneous fission.

Soluble (S): Insoluble (1).

"2.Sub" means that values given are for submersion in a semispherical infinite cloud of airborne material.

These radon concentrations are appropriate for protection from radon-222 combined with its short-lived daughters. Altematively, the value in Table 1 may be replaced by one-third (1/3) "working level." (A "working level" is defined as any combination of short-lived radon-222 daughters, polonium-218, lead-214, bismuth-214 and polonium-214, in one liter of air, without regard to the degree of equilibrium, that will result in the ultimate emission of 1.3 x 105 MeV of alpha particle energy.) The Table II value may be replaced by one-thirtieth (1/30) of a "working level." The limit on radon-222 concentrations in restricted areas may be based on an annual average.

For soluble mixtures of U-238, U-234 and U-235 in air chemical toxicity may be the limiting factor. If the percent by weight-enrichment of U-235 is less than 5, the concentration value for a 40-hour workweek, Table I is 0.2 milligrams uranium per cubic meter of air average. For any enrichment, the product of the average concentration and time of exposure during a 40-hour workweek SHALL NOT exceed 8 x 10*

SA jiCi-hr/ml, where SA is the specific activity of the uranium inhaled. The concentration value for Table II is 0.007 milligrams uranium per cubic meter of air. The specific activity for natural uranium is 6.77 x 10-7 curies per gram U. The specific activity for other mixtures of U-238, U-235 and U-234, if not known SHALL be:

SA=3.6 x 10. curies/gram U 2

U-depleted SA=(0.4 + 0.38 E + 0.0034 E ) 106 E>0.72 where E is the percentage by weight of U-235, expressed as percent.

E SIn any case where there Is a mixture in air or water of more than one radlonuclide, the limiting values for purposes of this Appendix should be determined as follows:

1. Ifthe identity and concentration of each radionuclide in the mixture are known, the limiting values should be derived as follows: Determine, for each radionuclide in the mixture, the ratio between the quantity present in the mixture and the limit otherwise established in Appendix B for the specific radionuclide when not in a mixture. The sum of such ratios for all the radionuclides in the mixture may not exceed "1"(i.e., "unity")

EXAMPLE: Ifradionuclides A, B, and C are present in concentrations C4, C. and Cr, and if the applicable MPC's, are MPCG, and MPC, and MPCc respectively, then the concentrations SHALL be limited so that the following relationship exists:

(CA/MPC,)+(C 6/MPC 5)+(Cc/MPCc) < 1

They may be adjusted as necessary to allow a reasonable margin to the monitor setpoint. Duplicate values of Tm are assigned to both Shield Building vents since only one containment will be purged at any one time. The assigned Tm values of all active release points SHALL NOT be greater than unity.

NOTE: ý-ý'..IWhen purging the Unit 1 containment via the inservice purge system, the monitor setpoints may be based on

For a particular measurement system (which may include radiochemical separation):

4 .66sb LLD =

E.V.2.22.Y.exp(-2 A r)

Where:

LLD is the apriori lower limit of detection as defined above (as picocurie per unit mass or volume), Sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute). In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background SHALL include the typical contributing of other radionuclides normally present in the samples (e.g., potassium-40 in milk samples). Typical values of E, V, Y and At SHALL be used in the calculations.

E is the counting efficiency (as counts per transformation),

2.22 is the number of transformation per minute per picocurie, Y is the fractional radiochemical yield (when applicable),

X% is the radioactive decay constant for the particular radionuclide, and A-t is the elapsed time between sample collection (or end of the sample collection period) and time of counting.

b - Drinking water pathway limit.

c - Total for parent and daughter d - These LLDs apply only where 01311 analysis" is specified.

e - Where "Gamma Isotopic Analysis" is specified, the LLD specification applies to the following radionuclides:

54 Mn, 59 Fe, 58CO, 6 0 0o, 65Zn, *Zr-Nb, 137Cs, 134 Cs, and 14 0Ba-La. Other peaks which are measurable and identifiable, together with the above nuclides, SHALL also be identified and reported.

OFFSITE DOSE CALCULATION MANUAL (ODCM) REV: 16 Page 157 of 219 Appendix A Summary of Dispersion Calculational Procedures Undepleted, undecayed dispersion parameters were computed using the computer program XOQDOQ (Sagendorf and Goll, 1977). Specifically, sector average X/Q and D/Q values were obtained for a sector width of 22.5 degrees. Building wake corrections were used to adjust calculations for ground-level releases. Standard open terrain recirculation correction factors were also applied as available as default values in XOQDOQ.

Dispersion calculations were based on ground level releases for the shield buildings, turbine buildings, and auxiliary building (hereafter referred to as the plant complex). A summary of release conditions used as input to XOQDOQ is presented in Table A-1 and controlling site boundary distances are defined in Table A-2. Computed X/Q and D/Q values for site boundary locations (relative to release points) and for standard distances (to five miles from the source in 0.1 mile increments) are presented in Tables A-3 through A-8.

Onsite meteorological data for the period April 1, 1977 through March 31, 1978 (as presented in Appendix B) were used as input to XOQDOQ. Data were collected and AT stability classes were defined in conformance with NRC Regulatory Guide 1.23. DIspersion calculations for the plant complex were based on AT 42.7-12.2m and 12.2 meter wind data (joint data recovery of 96 percent).

MANUAL (ODCM) REV: 16 Page 207 of 219 Appendix C - Dose Parameters for Radioiodines, Particulates and Tritium This appendix contains the methodology which was used to calculate the dose parameters for radioiodines, particulates, and tritium to show compliance with 10CFR20 and Appendix I of 10CFR50 for gaseous effluents. These dose parameters, Pi and Ri, were calculated using the methodology outlines in NUREG-0133 along with Regulatory Guide 1.109 Revision 1. The following sections provide the specific methodology which was utilized in calculating the Pi and Ri values for the various exposure pathways.

C.1 Calculation of Pi The parameter, Pi, contained in the radioiodine and particulates portion of Section 5.2, includes pathway transport parameters of the ith radionuclide, the receptor's usage of the pathway media and the dosimetry of the exposure. Pathway usage rates and the internal dosimetry are functions of the receptor's age: however, the child age group, will always receive the maximum dose under the exposure conditions assumed.

C.1.1 Inhalation Pathway Pi, = K' (BR) DFA, (C.1-1) where:

Pi = dose parameter for radionuclide i for the 3 ,

inhalation pathway, mrem/yr per ýici/m K' = a constant of unit conversion:

= 106 pCi/pCi; BR = the breathing rate of the child age group, m3/yr; DFA = the maximum organ inhalation dose factor for the child age group for radiQnuclide i, mrem/pCi.

The inhalation dose factors for the child DFA1 , are presented in Table E-9 of Regulatory Guide 1.109 in units of mrem/pCi. The total body is considered as an organ in the selection of DFAi. The incorporation of breathing rate of the child and the unit conversion factor results in the following:

P = 3.7 x 109 DFAi (C.1-2)

C.2 Calculation of Ri The radioiodine and particulate specification is applicable to the location in the unrestricted area where the combination of existing pathways and receptor age groups indicates the maximum potential exposure occurs. The inhalation and ground plane exposure pathways SHALL be considered to exist at all locations. The grass-goat-milk, the grass-cow-milk, grass-cow-meat, and vegetation pathways are considered based on their existence at the various locations. Ri values have been calculated for the adult, teen, child, and infant age groups for the ground plane, cow milk, goat milk, vegetable and beef ingestion pathways. The methodology which was utilized to calculate these values is presented below.

C.2.1 Inhalation Pathway R= K' (BR)a (DFA)a (C.2-1) where:

R,* = dose factor for each identified radionuclide I of the organ of interest, mrey/yr per pCi/m 3 K' = a constant of unit conversion:
