With the calculated dose from the release of iodine-131, tritium, and radionuclides in particulate form with half-lives greater than 8 days, in gaseous effluents exceeding any of the above limits, in lieu of any other report, prepare and submit a special report to the Com-mission within 30 days,' pursuant to Specification 6.12.5.

C. The provisions of Specifications 3.0.3, 3.0.4, and 6.12.3 are not applicable.

Bases:

Specification 3.25.2.3 implements the design guides set forth in 10 CFR 50 Appendix I, Section II C and the limiting conditions for operation as set forth in Appendix I,Section IV A.

The specifications provide the required 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 materials in gaseous effluents will be kept "as low as reasonably achievable".

Radioactiva Giseous Efflu nts 3.25.2.4 Gaseous Radwaste Treatment Applicability: At all times Objective:

To assure that the amount of radioactive material in gaseous effluents is "as low as reasonably achievable."

Specifications:

3.25.2.4 A. Ventilation exhaust treatment systems shall be used to reduce radioactive materials in gaseous waste prior to discharge when the projected doses due to gaseous ef-fluent releases from ANO-1 to unrestricted areas (see Figure 5.1-1) would exceed 0.625 mrad for gamma radiation and 1.25 mrad for beta radiation over a calendar quarter; or when the projected deses due to iodine-131, tritium, and radionuclides in particulate form with half-lives greater than 8 days would exceed 1.0 mrem to any organ over a calendar quarter.

B. When degasifying the reactor coolant system, the gaseous radwaste treatment system shall be utilized to process the degassing effluent to reduce the concentration of ra-dioactive materials prior to discharge when the projected doses due to gaseous effluent releases from ANO-1 to un-restricted areas (see Figure 5.1-1) would exceed 0.625 mrad for gamma radiation and 1.25 mrad for beta radiation over a calendar quarter.

C. With gaseous waste being discharged without treatment and in excess of the above limits, in lieu of any other re-port, prepare and submit to the Commission within 30 days a special report, per Specification 6.12.5.

D. The provisions of Specification 3.0.3, 3.0.4 and 6.12.3 are not applicable.

Bases:

The requirement that the appropriate portions of these systems be used when specified provides reasonable assurance that the releases of radio-active materials in gaseous effluents will be kept "as low as

( reasonably achievable." 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 1, 10 CFR Part 50, for gaseous effluents. The values 0.625 mrad, 1.25 mrad, and i 1.0 mrem are approximately 25% of the yearly design objectives on a quarterly basis. The yearly design objectives are given in Specifications 3.25.2.2 and 3.25.2.3.

To restrict the amount of activity in a radioactive gas holdup tank.

Specifications:

3.25.2.5 A. The quantity of radioactivity contained in each gas storage tank shall be limited to 300,000 curies noble gases (Xe-133 equivalent).

B. With the quantity of radioactive material in any gas storage tank exceeding the above limit, immediately suspend all additions of radioactive material to the tank and within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> reduce the tank contents to within the limit. -

C. The provisions of Specification 3.0.3 and 3.0.4 are not applicable.

Bases:

The value of 300,000 curies is a suitable fraction of the quantity of radioactive material which if released over a 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> period, would result in a total body exposure to a member of the public at the exclusion area boundary of 500 mrem.

RADI0 ACTIVE EFFLUENTS 3.25.3 Total Dose Applicability: At all times Objective: To ensure that the limits of 4C CFR 190 are not exceeded.

I Spectfications:

-3.25.3.1 The calculated doses from the release of radioactive materials in liquid or gaseous effluents shall not exceed twice the limits of Specification 3.25.1.2,_3.25.2.2, or 3.25.2.3.

3.25,3'.2 With the calculated doses exceeding the above limits, prepare and submit a Special Report pursuant to 10CFR Part 20.405C.

3.25.3.3 If the limits of 40CFR190 have been exceeded, obtain a vari-ance from the Commission to permit further releases in excess of 40CFR190 limits. A variance is granted until staff action

, on the request is complete.

i 3.25.3.'4 The provisions of Specifications 3.0.3 and 3.0.4 are not applicable.

L Bases:

This specification is provided to meet the dose limitations of 40 CFR 190 that have now been incorporated into 10 CFR Part 20. The specifi-cation requires the preparation and submittal of a Special Report when-ever the calculated doses from plant radioactive effluents exceed twice the. design objective doses of Appendix I. For sites containing up to 4 reactors, it is highly unlikely that the resultant dose to a member of the public will exceed the dose limits of 40 CFR 190 if the individual reactors remain within the-reporting requirement level. The Special Re-1 port will describe a course of action that should result in the limita-tion of the annual dose to a member of the public to within the 40 CFR 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 L fuel. cycle sources is negligible, with the exception that dose contribu-l tions from other nuclear fuel cycle facilities within a radius of 8 km IL must be considered. If the dose to any member of the public is estimated

to exceed the requirements of 40 CFR 190, the Special Report with a L request for a variance (provided the release conditions resulting in I. violation of 40 CFR 190 have not already been corrected), in accordance H with the provisions of 40 CFR 190.11 and 10 CFR 20.405c, is considered

to be a timely request and fulfills the requirements of 40 CFR 190 until

'NRC. staff. action is completed. The variance only relates to the limits of 40 CFR 190, and does not apply in any way to the other requirements for-dose limitation of 10 CFR 20, as addressed in Specifications 3.25.1

and 3.25.2. 'An individual is not considered to be a member of the public during any period in which he/she is engaged in carrying out any opera-tion that is part of the nuclear fuel cycle.

4.29 RADI0 ACTIVE EFFLUENTS 4.29.1 Radioactive Liquid Effluents 4.29.1.1 Concentration Applicability: At all times Objective: To ensure that the limits of Specification 3.25.1.1 are met.

Specifications:

4.29.1.1 Radioactive liquid wastes shall be sampled and analyzed according to the sampling and analyses program of Table 4.29-1.

4.29.1.2 The results of the radioactivity analyses shall be used in accordance with the ODCM to assure that the concentra-tions at point of release are maintained within the limits of Specification 3.25.1.1.

Bases:

This specification 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 10 CFR Part 20, Appendix B, Table II. This limitation provides additional assurance that the levels of radioactive materials in bodies of water outside the site will not result in exposures greater than the Section II A design objectives of Appendix I, 10 CFR Part 50, to an individual. The concentration limit for noble gases is based upon the assumption that Xe-133 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.

The Lower Limit of Detection (LLD) is the smallest concentration of radioactive material in a sample that will be detected with 95%

probability with 5% probability of falsely concluding that a blank observation represents a "real" signal.

For a particular measurement system (which may include radio-chemical separation):

LLD = 4.66 S b E V 2.22 Y exp(-Aat) where LLD is the lower limit of detection as defined above (as pCi per unit mass or volume) h is the standard deviation of the background counting rate s

or of the counting rate of a blank sample (in counts per minute).

E is the counting efficiency (as counts per transformation)

V is the sample size (in units of mass or volume) 2.22 is the number of transformations per minute per picocurie Y is the fractional radioche:nical yield (when applicable)

A is the radioactive decay constant for tne particular radionuclide at is the elapsed time between sample collection (or end of the sample collection period) and time of counting Typical values of E, V, Y, and at should be used in the calculation.

It should be recognized that the LLD is an a Priori (before the fact) limit representing the capability of a measurement system and not an a Posteriori (after the fact) limit for a particular measurement.

b. For certain mixtures of gamma emitters, it may not be possible to measure. radionuclides in concentrations near their sensitivity limits when other nuclides are present in the sample in much greater cor.centrations. Under these circumstances, it will be more appropriate to calculate the concentration of such radionuclides using observed ratios with those radionuclides which are measurable.

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

d. A batch release is the di: charge of liquid wastes of a discrete volume. Prior to sampling, each batch shall be isolated and mixed to ensure representative sampling.

e. The principal gamma emitters for which the LLD specification will apply are exclusively the following radionuclides: Mn54, Fe59, CoS8, Co60, Zn65, Mo99, Cs134, Cs137, Cel41, and Ce144. This list does not mean that only these nuclides are to be detected and re-ported. Other peaks which are measurable and identifiable, together with the above nuclides, shall 11so be identified and reported.

Nuclides which are below the LLD for the analyses should not be reported as being present at the Liu sevel. When unusual circum-stances result in LLD's higher than required, the reasons shall be documented in the Semiannual Radioactive Effluent Release Report.

4.30 RADIOLOGICAL ENVIRONMENTAL MONITORING 4.30.1 Radiological Environmental Monitoring Program Description Applicability: Applies at all times.

Objective: To provide information on the radiological effects of station operation on the environment.

Specifications:

4.30.1.1 The radiological environmental monitoring samples shall be collected pursuant to Table 4.30-1 and shall be analyzed pursuant to the requirements of Tables 4.30-1 and 4.30-2.

The sample locations shall be shown in Table 4-1 in the ODCM.

4.30.1.2 a. With the radiological environmental monitoring program not being conducted as specified in Table 4.30-1, prepare and submit to the Commission in the Annual Radiological Environmental Report a description of the reasons for not conducting the program as required and the plans for preventing a recurrence. (Deviatians are permitted from the required sampling schedule if specimens are not obtainable due to hazardous conditions, seasonal unavailability, or to malfunction of sampling equipment.

If the latter, every effort shall be made to complete corrective action prior to the end of the next sampling period).

b. With the level of radioactivity as the result of plant effluents in an environmental sampling medium at one or more of the locations specified in Table 4.30-1 exceeding the limits of Tahle 4.30-3 when averaged over any calendar quarter, prepare and submit to the Commission, within 30 days from the end of the affected quarter, a report which includes an evaluation of any release conditions, environmental factors or other aspects which caused the limits of Table 4.30-3 to be exceeded, and defines the actions taken to reduce radioactive effluents so that the potential annual dose to a member of the public is less than the l calendar year limits of Specifications 3.25.1.2 and 3.25.2.2. When more than one of the radionuclides in Table 4.30-3 are detected in the sampling medium, this report shall be submitted if:

Concentration (1) Concentration (2) + "**' > 1.0 reporting level (1) reporting level (2) -

When radionuclides other than those in Table 4.30-3 are detected and are the result of plant effluents, this repcrt shall be submitted if the potential j annual dose to a member of the public is equal to or l

110ss l

greater than the calendar year limits of Specifica-tions 3.25.1.2 and 3.25.2.2. This report is not re-quired if the measured level of radioactivity was not the result of plant effluents, however, in such an event, the condition shall be reported and de-scribed in the Annual Radiological Environmental Re-port.

c. With milk or fresh leafy vegetable samples unavailable from any of the sample locations required by Table 4.29-1, identify locations for obtaining replacement samples and add them to the radiological environmental monitoring program within 30 days. The specific locations from which samples were unavailable may then be deleted from the monitoring program.

Identify the causes of the unavailability of samples and identify the new location (s) for obtaining re-placement samples in the next Semiannual Radioactive Effluent Release Report and also include in the re-port a revised table for the ODCM reflecting the new location (s).

d. The provisions of Specifications 3.0.3, 3.0.4, and 6.12.3 are not applicable.

4.30.1.3 The results of analyses performed on the radiological environmental monitoring samples shall be summarized in the Annual Radiological Environmental Report.

Bases:

The radiological monitoring program required by this specification provides measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides which lead to the highest potential radiation exposures of individuals resulting from the station operation. This monitoring program thereby supplements the radiological effluents monitoring program by verifying that the measurable concentratiens of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways. The initially specified monitoring program will be effective for at least the first three years of commercial operation. Following this period, program changes may be initiated based on operational experience.

The detection capabilities required by Table 4.30-2 are state-of-the-art for routine environmental measurements in industrial laboratories. The LLD's for drinking water meet the requirements of 40 CFR 141.

Radiological Environmental Monitoring 4.30.2 Land Use Census

, Applicability: Applies at all times.

Objectives: This specification will identify changes in use of the unrestricted areas.

Specifications:

f 4.30.2.1 A land use census shall be conducted and shall identify the location of the nearest milk animal, the nearest residence, and the nearest garden

• of greater than 500 square feet producing fresh leafy vegetables in each of the 16 meteorological sectors within a distance of five miles from the ANO-1 reactor building.

4.30.2.2 The land use census shall be conducted at least once per 12 months between the dates of June 1 and October 1, by door-to-door survey, aerial survey, or by consulting local agricultural authorities.

4.30.2.3. a. With a land use census identifying a location (s) which yields a calculated dose commitment due to I-131, tritium, and radionuclides in particulate form greater than the values currently being calculated in Unit I Specification 4.29.3 and Unit 2 Specification 4.11.2.3 submit location description in the Semiannual Radioactive Effluent Release Report per Specification 6.12.2.6.

b. With a land use census identifying a location (s) which yields a calculated dose commitment (via the same exposure pathway) greater than at a location from which samples are currently being obtained in accordance with Specification 4.30.1.1. The new location shall be added to the radio-logical environmental monitoring program within 30 days, if possible. The sampling location having the lowest calculated dose commitment (via the same exposure pathway) may be deleted from this monitoring program after (October

31) of the year in which this land use census was con-ducted.

4.30.2.4 The results of the land use census shall be included in the Annual Radiological Environmental Report.

4.30.2.5 The provisions of Specifications 3.0.3, 3.0.4 and 6.12.3 are not applicable.

• Broad Leaf vegetation sampling may be performed at the site boundary in the direction sector with the highest D/Q in lieu of the garden census.

110zz 1

Basts:

This specification is provided to ensure that changes in the use of unrestricted areas are identified and that modifications to the monitoring program are made if required by the results of this census.

This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50. Restricting the census to gardens of greater than 500 square feet provides assurance that significant exposure pathway via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26kg/ 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.

110aaa

Radiological Environmental Monitoring 4.30.3 Interlaboratory Comparison Program Applicability: Applies to the off-site radiochemistry laboratory Objective: To provide independent checks on the accuracy of the neeasurements of radioactive material in environmental-samples.

a. The LLD is the smallest concentration of radioactive material in a sample that will be detected with 95% probability with 5% probabil-ity of falsely concluding that a blank observation represents a "real" signal.

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

4.66 s b LLD = E V 2.22 Y exp (-AAt)

Where:

LLD is the lower limit of detection as defined above (as pico-curie per unit mass or volume).

ss is the standard deviation of the background counting rate or oY the counting rate of a blank sample as appropriate (as counts per minute).

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

ARKANSAS - UNIT 2 3/4 11-2

~

TABLE 4.11-1 (Continued) ,

V is the sample size (in units of mass or volume).

2.22 is the number of transformations per minute per picocurie.

Y is the fractional radiochemical yield (when applicable).

A is the radioactive decay constant for the particular radio-nuclide, and At is the elapsed time between midpoint of sample collection and time of counting (for plant effluents, not environmental samples).

Typical values of E, V, Y, and at shall be used in the calculation.

It should be recognized that the LLD is an a priori (before the fact) limit representing the capability of a measurement system and not an a posteriori (after the fact) limit for a particular measurement.

b. For certain mixtures of gamma emitters, it may not be possible to measure radionuclides in concentrations near their sensitivity limits when other nuclides are present in the sample in much greater concentrations. Under these circumstances, it will be more appropriate to calculate the concentration of such radionuclides using observed ratios with those radionuclides which are measurable,

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

c. A batch release is the discharge of liquid wastes of a discrete volume. Prior to sampling, each batch shall be isolated and mixed to assure representative sampling.

e. The principal gamma emitters for which the LLD specification will apply are exclusively the following radionuclides: Mn54, Fe59, CoS8, Co60, Zn65, Mo99, Cs134, Cs137, Cel41, and Ce144. This list does not mean that only these 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. 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 LLD's higher than required, the reasons shall be documented in the Semiannual Radioactive Effluent Release Report.

TABLE NOTATJON a.

The Lower Limit of Detection (LLD) is defined in Table Notation a.

of Table 4.11-1 of Specification 3.11.1.1.

b. The principal gamma emitters for which the LLD specification will apply are exclusively the following radionuclides: Kr-87, Kr-88, Xe-133, Xc-133m, Xe-135, and Xe-138 for gaseous emissions and Mn-54, Fe-59, Co-58, Co-60, Zn-65, Ho-99, Cs-134, Cs-137, Ce-141 and Ce-144 for particulate emissions. This list does not mean that only these 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. Nuclides which are below the LLD for the analyses should not be reported as being present at the LLD level for that nuclide. When unusual circumstances result in LLD's higher than required, the reasons shall be documented in the semiannual effluent report.

c. Tritium grab samples shall be taken from the Reactor Building ventilation exhaust at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when the refueling canal is flooded.

d. Tritiom grab samples shall be taken at least once per 7 days from the ventilation exhaust from the spent fuel area, whenever spent fuel is in the spent fuel pool,

e. The ratio of the sample flow rate to the sampled stream flow rate 4

shall be known for the time period covered by each dose or dose rate calculation made in accordance with Specification 3.11.2.1, 3.11.2.2, and 3.11.2.3.

f. Samples shall be changed at least once per 7 days and analyses shall be completed within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after changing (or af ter removal from the sampler).

g. For certain radionuclides with low gamma yield or low energies, or for certain radionuclide mixtures, it may not be possible to measure radionuclides in concentrations near the LLD. Under these circum-stances, the LLD may be increased inversely proportional to the magnitude of the gamma yield (i.e., 1 x E-4/I, where I is the photon abundance expressed as a decimal fraction), but in no case shall the LLD, as calculated in this manner for a specific radionuclide, be greater than 10% of the MPC value specified in 10 CFR 20, Appendix B, Table II, Column I.

_ INSTRUMENTATION BASES 3/4.3.3.6 POST-ACCIDENT INSTRUMENTATION The OPERABILITY of the post-accident instrumentation ensures that suffi-cient information is available on selected plant parameters to monitor and assess these variables following an accident. This capability is consistent with the recommendations of Regulatory Guide 1.97, "Instru-mentation for Light-Water-Cooled Nuclear Plants to Assess Plant Condi-tions During and Following an Accident," December 1975 and NUREG-0578, "TMI-2 Lessons Learned Task Force Status Report and Short Term Recommendations."

3/4.3.3.7 CHLORINE DETECTION SYSTEMS The OPERABILITY of the chlorine detection system ensures that sufficient capability is available to promptly detect and initiate protective action in the event of an accidental chlorine release. This capability is required to protect control room personnel and is consistent with the recommendations of Regulatory Guide 1.95, " Protection of Nuclear Power Plant Control Room Operators Against an Accidental Chlorine Release,"

Fcbruary 1975.

3/4.3.3.8 FIRE DETECTION INSTRUMENTATION OPERABILITY of the fire detection instrumentation ensures that adequate warning capability is available for the prompt detection of fires. This capability is required in order to detect and locate fires in their early stages. Prompt detection of fires will reduce the potential for damage to safety related equipment and is an integral element in the overall facility fire protection program.

In the event that a portion of the fire detection instrumentation is in-operable, except for detectors located in the containment during Modes 1 and 2, the establishment of frequent fire patrols in the affected areas is required to provide detection capability until the inoperable instrumentation is restored to OPERABILITY.

design objectives of-Appendix I, 10 CFR Part 50, to a MEMBER OF THE

. PUBLIC, and (2) the limits of 10 CFR Part 20, 106(e) to the population.

.The concentration limit for dissolved or entrained noble gases is based 4

upon the assumption that Xe-133 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.

3/4.11.1.2 DOSE Provides assurance that releases of liquid effluents will result in con-

-The requirement that the appropriate portions of this system be used, when specified, provides assurance that the releases of radioactive materials in liquid' effluents will be kept "as low as is reasonably achievable". The specified limits governing the use of appropriate portions of the LIOUID RADWASTE TREATMENT SYSTEM were specified as a suitable fraction cf the dose design objectives set forth in Section II.A of Appendix I, 10 CFR Part 50, for liquid effluents.

The values of .18 mrem and .625 mrem are approximately 25% of the yearly design objectives on a quarterly basis. The yearly design objectives are given in 10CFR50, Appendix I, Section II.

3/4.11.1.4 LIQUID HOLDUP TANKS-Restricting the quantity of radioactive material contained in the speci-fied tanks provides assurance that in the event of an uncontrolled release of the contents of'the tanks, the resulting concentrations would be less than the limits of 10 CFR Part 20, Appendix B, Table II, Column 2, at the nearest potable water supply and the nearest surface water supply in an UNRESTRICTED AREA.

This specification applies to the release of gaseous effluents from all reactors at the site.

3/4.11.2.2 DOSE-NOBLE GASES This specification is provided to implement the requirements of Sections II.B. III.A, and IV.A of Appendix I, 10 CFR Part 50. The Limiting Condition for Operation implements the guides set forth in Section II.B of Appendix I. The action statements provide the required 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 gaseous effluents will be kept "as low as is reasenably achievable." The Surveillance Requirements implement the requicaments in Section III. A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of a member of the public through appropriate path-ways is unlikely to be substantially underestimated. The dose calcula-tions established in the ODCM for calculating the doses due to the actual release rates of radioactive noble gases in gaseous effluents are consis-tent with the methodology provided in Regulatory Guide 1.109, " Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I,"

Revision 1, October 1977 and Regulatory Guide 1.111, " Methods for Estima-ting Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water Cooled Reactors," Revision 1, July 1977. The ODCM equations provided for determining the air doses at and beyond the site boundary are based upon the historical average atmospheric conditions.

The Limiting Conditions for Operation are the guides set forth in Section II.C of Appendix I. The action statements provide the required 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 materials in gaseous effluents will be kept "as low as is reasonably achievable". The ODCM calculational methods specified in the Surveillance Requirements implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data, such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The ODCM calculational methods for calculating the doses due to the actual release rates of the subject materials are consistent with the methodology provided in Regulatory Guide 1.109, " Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision I, October 1977 and Regulatory Guide 1.111., " Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors," Revision 1, July 1977. These equations also provide for determining the actual doses based upon the historical average atomospheric conditions. The release rate. specifications for iodine-131, tritium, and radionuclides in particulate form with I half-lives greater than 8 days are dependent on the existing radionuclide lpathwaystomanintheareasatorbeyondthesiteboundary.Thepathways that were examined in the development of these calculations were: 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.

3/4.11.2.4 and.5 GATE 0US RADWASTE TREATMENT The requirement that the appropriate portions of these systems be used, when specified, provides reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept "as low as is reasonably achievable".

RADI0 ACTIVE EFFLUENTS BASES 3/4.11.2.6 GAS STORAGE TANKS The tanks included in this specification are those tanks for which the quantity of radioactivity contained is not limited directly or indirectly by another Technical Specification tn a quantity that is less than the quantity which provides assurance that in the event of an uncontrolled release of the contents of the tank, the resulting total body exposure to a MEMBER OF THE PUBLIC at the nearest EXCLUSION AREA boundary will not exceed 0.5 rem in an event of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.

Restricting the quantity of radioactivity contained in each gas storage tank provides assurance that in the event of an uncontrolled release of the tanks's contents, the resulting total body exposure to a MEMBER OF THE PUBLIC at the nearest EXCLUSION AREA boundary will not exceed 0.5 rem. This is consistent with Branch Technical Position ETS8 11-5 in NUREG-0800, July, 1981. -

3/4.11.3 TOTAL DOSE This specification is provided to meet the dose limitations of 40 CFR Part 190 that have now been incorporated into 10 CFR Part 20 by 46 FR 18525. The specification requires the preparation and submittal of a Special Report whenever the calculated doses from plan radioactive effluents exceed twice the design objective doses of Appendix I. For sites containing up to 4 reactors it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the individual reactors remain within the reporting requirement level. 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 the 40 CFR 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 re-quirements of 40 CFR Part 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected), in accordance with the provisions of 40 CFR Part 190.11 and 10 CFR Part 20.405c, is con-sidered to be a timely request and fulfills the requirements of 40 CFR Part 190 until NRC staff action is completed. The variance only relates to the limits of 40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR Part 20, as addressed in Specifications 3.11.1 and 3.11.2. 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.
