License Nos. DPR-51 and NPF-6

Dear Sir or Madam:

Arkansas Nuclear One, Units 1 & 2 (ANO-1 and ANO-2) Technical Specifications (TSs) 5.6.3 and 6.6.3, respectively, require the submittal of an Annual Radioactive Effluent Release Report.

10CFR72.44(d)(3) also requires the annual submittal of a summary of effluents from the independent spent fuel storage facility. The enclosed compact disc contains the information to fulfill these reporting requirements for the 2006 calendar year at ANO.

Liquid and gaseous release data show that the dose from both ANO-1 and ANO-2 was considerably below the Offsite Dose Calculation Manual (ODCM) limits, while no effluents were attributed to the spent fuel stored in the independent spent fuel storage installation. This data reveals that the radioactive effluents had an overall minimal dose contribution to the surrounding environment. Pursuant to ANO-1 TS 5.5.1 and ANO-2 TS 6.5.1, the ODCM is submitted as an attachment to the Annual Radioactive Effluent Release Report. A copy of the Process Control Program is also attached. Should you have any questions regarding this report, please contact Richard Scheide at (479) 858-4618.

There are no new commitments contained in this submittal.

Sincerely, DalIe .J /es Manag/, Licensing DEJ s Attachments Aj 70 A ch/7

1. INTRODUCTION Arkansas Nuclear One (ANO) is a two unit site consisting of a Babcock & Wilcox (Unit 1) and a Combustion Engineering (Unit 2) nuclear steam supply system. Both liquid and gaseous effluents are released in accordance with the Offsite Dose Calculation Manual (ODCM). This report is a summary of the effluent data in accordance with Unit 1 TS 5.6.3 and Unit 2 TS 6.6.3. This report provides the following information:

A. Routine radioactive effluent release reports covering the operation of the units and the independent spent fuel storage installation (ISFSI) during the reporting period.

B. Description of unplanned releases to unrestricted areas.

C. Description of changes to the Offsite Dose Calculation Manual (ODCM).

D. Description of changes to the Process Control Program (PCP).

E. Summary of radiation doses due to radiological effluents' during the previous calendar year.

F. Radiation dose to members of the public due to activities inside the site boundary.

G. Description of licensee initiated major changes to the radioactive waste systems during the previous calendar year.

H. Items to be reported in the annual Radioactive Effluent Release Report per other miscellaneous ODCM requirements.

This report covers the period from January 1 through December 31, 2006.

2. ' REGULATORY LIMITS The ODCM contains the limits to which ANO must adhere. Because of the "as low as reasonably achievable" (ALARA) philosophy at ANO, an attempt is made to reduce the amount of radiation released to the environment. Liquid and gaseous release data show that the dose from both Unit 1 and Unit 2 is considerably below the ODCM limits. This data reveals that the radioactive effluents have an overall minimal dose contribution to the surrounding environment. The following are the limits required by the ODCM:

3

A. Gaseous Effluents

1. Dose rate due to radioactive materials released in gaseous effluent to unrestricted areas shall be limited to the following:

a. Noble gases Less than or equal to 500 mrem/year to the total body Less than or equal to 3000 mrem/year to the skin

b. Iodine- 131, tritium, and for all radionuclides in particulate form with half lives greater than 8 days Less than or equal to 1500 mrem/yr to any organ

2. Dose - Noble Gases Quarterly Less than or equal to 5 mrads gamma Less than or equal to 10 mrads beta Yearly Less than or equal to 10 mrads gamma Less than or equal to 20 mrads beta

3. Dose - Iodine- 131, Tritium, and Radionuclides in Particulate Form Quarterly Less than or equal to 7.5 mrems to any organ Yearly Less than or equal to 15 mrems to any organ 4

B. Liquid Effluents

1. Concentration The concentration of radioactive material released to the discharge canal shall be limited to the concentration specified in 10CFR20, Appendix B, Table II, Column 2, for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the total concentration released shall be limited to 2E-4 microcuries/ml.

2. Dose Quarterly Less than or equal to 1.5 mrem total body Less than or equal to 5 mrem critical organ Yearly Less than or equal to 3 mrem total body Less than or equal to 10 mrem critical organ 5

1.0 INTRODUCTION

The Offsite Dose Calculation Manual (ODCM) provides guidance for making release rate and dose calculations for radioactive liquid and gaseous effluents from Arkansas Nuclear One - Units 1 and 2. The methodology is drawn from NUREG-0133, Rev. 0.

Parameters contained within this manual were taken from NUREG-0133 and Regulatory Guide 1.109 except as noted for site specific values. These numbers and the calculational method may be changed as provided for in the Technical Specifications.

The following references are utilized in conjunction with the limitations included in this manual concerning the indicated subjects:

Subject ANO-I ANO-2 Process Control Program (PCP) NMM RW-105 NMM RW-105 Radioactive Effluent Controls Program TS 5.5.4 TS 6.5.4 Annual Radiological Environmental Monitoring Report TS 5.6.2 TS 6.6.2 Radioactive Effluent Release Report TS 5.6.3 TS 6.6.3 Offsite Dose Calculation Manual TS 5.5. 1 TS 6. 5. 1

2.0 LIQUID EFFLUENTS 2.1 Radioactive Liquid Effluent Monitor Setpoint The Radioactive Liquid Effluent Instrumentation Limitation requires that the radioactive liquid effluents be monitored with the alarm/trip setpoints adjusted to ensure that the limits of the radioactive liquid effluent concentration limitations are not exceeded. These concentrations are for the site. The alarm/trip setpoint on the liquid effluent monitor is dependent upon the dilution water flowrate, radwaste tank flowrate, isotopic composition of the radioactive liquid to be discharged, a gross gamma count of the liquid to be discharged, background count rate of the monitor, and the efficiency of the monitor. Due to the fact that these are variables, an adjustable setpoint is used. The setpoint must be calculated and the monitor setpoint set prior to the release of each batch of radioactive liquid effluents. The following methodology is used for the setpoint determination for the following monitors.

ANO-I: RE-4642 Liquid Radwaste Monitor ANO-2: 2RE-2330 Liquid Radwaste Monitor 2RE-4423 Liquid Radwaste Monitor

1) A sample from each tank (batch) to be discharged is obtained and counted for gross gamma (Cs-137 equivalent) and a gamma isotopic analysis is performed.

2) A dilution factor (DF) for the tank is calculated based upon the results of the gamma isotopic analysis and the Maximum Permissible Concentration (MPC) of each detected radionuclide.

DF is calculated as follows:

DF = Z. (C./MPC.) ) + C TNG/MPCTNG where:

DF = dilution factor; C. = concentration of isotope "i", (ý1Ci/ml);

MPC. = maximum permissible concentration of isotope "i",

(from 10 CFR 20, Appendix B, Table II, column 2 in pCi/ml);

CTNG = total concentration of noble gases (ýiCi/ml); and MPCTNG = 2 x 10-4 (ýiCi/ml) per Appendix 1, Limitation L2.3.I.A and Appendix 2, Limitation L2.3.I.A.

3) The dilution water flowrate is normally the number of ANO-I circulating water pumps in operation at the time of release. Each circulating water pump has an approximate flowrate of 191,500 gpm (this flowrate may be reduced due to throttling of circ water pump flow and/or circ water bay configuration). However, under specific conditions and under strict controls, lower dilution water flowrates utilizing service water and cooling tower blowdown flowrates may be used.

4) The theoretical release rate, F , of the tank (batch) to be released m

is expressed in terms of the dilution water flowrate, such that for each volume of dilution water released, a given volume of liquid radwaste may be combined. This may be expressed as follows:

F = DV/DF m

where:

F = theoretical release rate (gpm);

m DV = Dilution volume (gpm). When ANO-l circulating water pumps are running, DV is the number of ANO-I circulating water pumps in operation multiplied by the approximate flowrate of an ANO-I circulating water pump (normally 191,500 gpm) or an indicated flow rate. The minimum total flow rate shall be greater than or equal to 100,000 gpm. Otherwise DV is dilution volume provided by service water and cooling tower blowdown flowrate; and DF = dilution factor as calculated in Step 2 above.

NOTE In the above equation, the theoretical release rate (F )

approaches zero as the dilution factor increases. The actual flowrate (F A) will normally be equal to the theoretical release rate for high activity releases.

For low activity releases, the theoretical release rate becomes large and may exceed the capacity of the pump discharging the tank. In these cases, the actual release rate may be set to the maximum flowrate of the discharge pump.

5) The monitor setpoint is calculated by incorporating the monitor reading prior to starting the release (i.e., background countrate),

and a factor which is the amount of increase in the release concentration that would be needed to exceed the radioactive liquid concentration limitation. The monitor setpoint is expressed as follows:

ML = A*(K*F M/F A) + B where:

M = monitor setpoint (CPM);

L A = allocation fraction for the specific unit. (Typically, these values are set at 0.45, but may be adjusted up or down as needed. However, the total site allocation can not exceed 1.0.)

K = monitor countrate (CPM) expected based on the gross activity of the release. (This value is obtained from a graph of activity (pCi/ml) versus output countrate for the monitor (CPM));

LICENSE NO. TITLE: PAGE: 7 of 173 075 OFFSITE DOSE CALCULATION MANUAL REV: 014-03-0

F M/FA = number of times the activity would have to increase to exceed the radioactive liquid effluent-concentration limitation; and B = background countrate (CPM) prior to the release.,

To permit the computer to calculate the setpoint, an equation for the expected countrate (K) is expressed as follows:

S A

K = Slope

10 + Offset where:

Slope -Log of the detector response in CPM Log of activity concentration in pCi/ml S = Gross gamma (Cs-137 equivalent) activity for the tank

(ýiCi/ml); and Offset = detector response (CPM) for the minimum detectable sample activity calculated from the calibration data.

NOTE I&C personnel use varying concentrations of Cs-137 to determine the response curve; therefore, a Cs-137 equivalent activity must be used to accurately predict the countrate.

Combining terms, the equation for determining the monitor setpoint may be expressed as follows:

S A

ML = A * [(Slope

10 + Offset)* FM/F A] + B 2.2 Liquid Dose Calculation The "dose" or "dose commitment" to an individual in the unrestricted area shall be less than or equal to the limits specified in Radioactive Liquid Effluents-Dose Appendix 1 and Appendix 2 Limitations. The dose limits are on a per reactor basis. This value is calculated using the Adult as the maximum exposed individual via the aquatic foods (Sport Freshwater Fish) and the potable water pathways.

2.2.1 Dose Calculations for Aquatic Foods The concentrations of radionuclides in aquatic foods are assumed to be directly related to the concentrations in water.

The equilibrium ratios between the two concentrations are called "bioaccumulation factors".

Two different pathways are calculated for aquatic foods: sport and commercial freshwater fish.

The internal dose "d" from the consumption of aquatic foods in pathway "p" to organ "j" of individuals of age group "a" from all nuclides "i" is computed as follows: (See Chapter 4 of NUREG-0133 and Regulatory Guide 1.109-12, equation A-3).

Guide 1.109-12, equation A-2):

These methods cover two different sets of monitors of which only one will be in-service at any one time.

3.1.1 Batch Release Setpoint Calculations 3.1.l.a This section applies to the following gaseous radiation monitors (These releases are also monitored by the SPING monitors in Section 3.1.2):

ANO-1 RE-4830* Waste gas holdup system monitor RX-9820 Unit 1 Containment Purge SPING ANO-2 2RE-8233 Containment purge 2RX-9820 Unit 2 Containment Purge SPING 2RE-2429* Waste gas holdup system monitor These monitors provide automatic isolation for the waste gas holdup systems.

The setpoints to be used during a batch type of release (i.e., reactor building [containment] purge, release from the waste gas holdup system or any other non-routine release) will be calculated for each release before it occurs.

3.1.l.b The basic methodology for determining a monitor setpoint is based upon the expected concentration at the monitor (CM ). This is in turn based upon the fraction of an MPC assigned to this release point.

Batch releases are maintained below the assigned MPC fraction by controlling the release rate. The calculated value of S may not exceed the equivalent of 1 MPC at site boundary. If value of S for RX(2RX)-9820 is less than SPING channel 5 high alarm setpoint, then high alarm setpoint may be used as a default value. If value of S for RE-4830 and 2RE-2429 is less than 50,000 counts/min, then 50,000 counts/min may be used as a minimum setpoint. If value of S for 2RE-8233 is less than 1,000 counts/min, then 1,000 counts/min may be used as a minimum setpoint.

S = 1.2 * (C *K) + (2.0

S = monitor setpoint (counts/min);

CM Xe-133 equivalent concentration at the monitor (IiCi/ml);

K conversion factor determined from response curve of monitor (counts/min per pCi/ml). This value is 1.0 when calculating S for RX(2RX)-

9820.

2.0 = factor to accommodate random count rate fluctuations; B background count rate at the monitor (counts/min).

1.2 = Safety Factor to correct for instrument uncertainties.

3.1.2 Eberline SPING (Final Effluent) Monitor Setpoint Calculations 3.1.2.a This section applies to the following gaseous radiation monitors:

ANO-1 RX-9820 Containment Purge RX-9835 Hydrogen Purge/Emerg. Pen. Room Vent.

2RX-9830 Fuel Handling Area 2RX-9825 Radwaste Area 2RX-9850 Low-Level Radwaste Storage Building The determination of setpoints for the above monitors is based on an assigned fraction of the MPC of noble gas activity at the site boundary, (Xe-133 equivalent) released from the above release points.

The total of these fractions is always less than 1.00. The assigned fractions are based on the vent flow rates, atmospheric dilution rate, and the ventilation system(s) in operation.

NOTE The fact that an effluent monitor is in alarm does not necessarily mean that radioactive gases are being released at such a rate that the MPC limit is being exceeded. The alarm would indicate that radioactive gases are being released at a rate that is exceeding the fractional allocation of an MPC allotted to that particular release point. Consideration must be given to the release rate of radioactive gases via all of the release pathways.

The initial fractions of an MPC allocated to the release points are given below. The allocations may be changed as needed, to allow for operational transients, but may not exceed a site total of 1.00.

3.2 Airborne Release Dose Rate Effects 3.2.1 Noble Gas Release Rate 3.2.1.a To calculate the noble gas release dose rate, the average ground-level concentration of radionuclide "i" at the receptor location must first be determined from the following equation. (See Regulatory Guide 1.109-20 equation B-4).

3.17xi0 4= number of pCi per Ci divided by the number of seconds/year; Q. = release rate of nuclide "i" in curies/yr and DlX/Q(0) = annual average gaseous dispersion factor (corrected for radioactive decay) in the sector at angle "0" at the receptor location in sec/m3. This value is 2.8E-6 sec/m3 for short term releases.

The annual dose to the total body and skin due to noble gas can be calculated according to Sections 3.1.2.b and 3.2.1.c.

3.2.1.b Annual Total Body Dose Rate The annual average total body dose rate to the maximally exposed individual is calculated as follows:

where:

DT(8) = total body dose rate due to immersion in a semi-infinite cloud of gas at the controlling distance in sector "0",

(WNW);

RBPF = Reactor Building (Containment) Purge Factor -

This factor is used to calculate the length of time (fractional duty cycle) that the purge fans will be in operation.

It is calculated by comparing the highest dose rate (DOSER) to its applicable release limit, taking into account the allocation factor for the release point (RBPF = Allocation*

Limit/DOSER). This factor is calculated only for Unit One and Two Reactor Building (Containment) Purges.

For all other releases, this factor is set to 1.0;'

SF = dimensionless attenuation factor accounting for the dose reduction due to shielding by residential structures. The NRC recommended value is 0.7 (for maximum individual);

which includes the attenuation of 5 g/cm2 of tissue, in mrem-m3/pCi-yr 3.2.1.c Annual Skin Dose Rate The annual dose rate to the skin of the maximally exposed individual due to noble gases is calculated as follows. (See Regulatory Guide 1.109-20 equation B-9)

in mrad-m3/pCi-yr; and DFS.1 beta skin dose factor for a semi-infinite cloud of radionuclide "i", which includes the attenuation by the outer "dead" layer of skin, in mrem-m 3 /pCi-yr.

3.2.2 1-131, Tritium and Particulate Release Dose Rate Effects The annual dose rate to the maximally exposed individual for 1-131, tritium and radionuclides in particulate form with half-lives greater than eight days is calculated as follows:

F_-

TOT DI DG MI DR = RBPF* [R +DR + DR]

where:

RBPF = Reactor Building (Containment) Purge Factor as defined in Section 3.2.1.b; I

DR = dose rate to the controlling age group (infant) associated with the inhalation of radioiodines and particulates, as calculated in Section 3.4.1.b; G

DR = dose rate from direct exposure to activity deposited on the ground plane, as calculated in Section 3.4.1.a; and M

DR = dose rate to the controlling age group (infant) and the controlling organ for ingestion of food (milk),

as calculated in Section 3.4.1.d.

Calculation of the annual dose rate considers the infant as the most restrictive age group. The organs that are considered as contributing to the dose rate are: skin, bone, liver, total body, thyroid, kidney, lung, and GI-LLI. The food pathway for the infant is considered to be from milk only. All three pathways will contribute to the total body dose, while the skin will be affected by only the ground plane pathway. The other organs are affected only by the inhalation and food pathways.

3.3 Dose Due to Noble Gases The air dose in unrestricted areas due to noble gases released in gaseous effluents shall be less than or equal to 5 mrad for gamma radiation and 10 mrad for beta radiation for any calendar quarter for each unit. The objective of less than or equal to 10 mrad of gamma radiation and 20 mrad of beta radiation for a calendar year per unit (2.5 mrad and 5 mrad respectively per quarter) should be used for planning releases.

NOTE The following equations have been simplified from equations in NUREG-0133, Rev. 0, in that there are no free-standing stacks at ANO.

The equations were further simplified in that there are no long term (i.e., continuous) releases. The individual stack vents are sampled weekly and are assigned a release period of 168 hours0.00194 days 0.0467 hours 2.777778e-4 weeks 6.3924e-5 months per sample (i.e., considered as short term (batch) releases). Individual samples are to be taken for each waste gas tank release and reactor building (containment) purge.

3.3.1 Beta and Gamma Air Doses from Noble Gas Releases Using the average ground level concentration of radionuclide "i" at the receptor location calculated in Section 3.2.1.a, the associated annual gamma or beta air dose may be calculated by the following equation. (See Regulatory Guide 1.109-20 equation B-5.)

3.4 Dose Due to 1-131, Tritium, and Particulates in Gaseous Effluents The calculational methodology for determining the dose to an individual from 1-131, tritium, and radionuclides in particulate form with half-lives greater than 8 days in gaseous effluents released to unrestricted areas as specified in the Appendix 1 and Appendix 2 Limitations is in this section.

The child is the controlling age group unless stated otherwise.

The inhalation and ground plane pathways are considered to exist at all locations. The grass-cow-milk, grass-cow-meat, and vegetation pathways are used where applicable.

It is assumed that iodines are in the elemental form.

A dispersion parameter of 2.8E-6 sec/m3 (per ANO-2 SAR, Section 2.3.4.4) is used for "w" in the inhalation pathway since the majority of gaseous activity released from the site is within the 8 to 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months time frame (i.e., reactor building [containment] purges and waste gas decay tanks).

3.4.1.c Dose from Nuclide Concentrations in Vegetation NOTE To reduce the computational overhead of the computer, the calculations for dose resulting from nuclide concentrations in forage, produce and leafy vegetables is performed in three steps.

First, the concentration factors (CF) are computed and stored in the database. The concentration factor includes all the parameters that are considered constant for each nuclide and agricultural activity, such as the radioactive decay constant, removal rate constant, exposure time, etc.

Second, the deposition rate from the plume is multiplied by the concentration factor and the nuclide activity to produce the nuclide concentration as follows:

v C.1 (r,O) = CF.1

DOQ(r,e)

Q.1 where:

Cv (r,O) = concentration of nuclide Ili" at the receptor location (r,O);

CF. = concentration factor of nuclide "i";

1 DOQ(r,O) = relative deposition of nuclide "i". For the short term dispersion option, DOQ is replaced by (F x DOQ), where F is the short term dispersion correction factor; Q. = quantity of nuclide "i" released in curies.

For carbon-14 and tritium, the nuclide concentration is calculated from the concentration factor times the decayed and depleted X/Q for radioiodines and particulates (D2DPX/Q), times the quantity of nuclide "i" released in curies. For the short term dispersion option, D2DPX/Q is replaced by F x D2DPX/Q, where F is the short term dispersion correction factor.

Cv C (r,O) = CF

D2DPX/Q(r,O)

Q for tritium, and T T T CFV14 (r,O) = CF14

D2DPX/Q(r,6)

Q14 for carbon-14 Third, the nuclide concentrations for a particular pathway (produce, leafy vegetables, cow's milk, and meat) are summed and multiplied by: 1) the ingestion rate for a particular age group and 2) the dose conversion factor:

D(r,e,j,a) = I. I (DFI..i3a

U a

C (r,O)I i

where:

r user-selected distance from the release point to the receptor location in a particular sector, in kilometers (1.05 km);

0 = one of sixteen 22.50 sectors surrounding the reactor site, designated N, NNE, NE

... etc., (WNW);

user-selected organ (bone, liver, total body, thyroid, kidney, lung, GI-LLI), and is the same controlling organ as that used for all airborne pathways; a user-selected age group (infant, child, teen, adult), and is the same controlling age group as that used for all airborne pathways; DFI..ija dose conversion factor for ingestion of nuclide "i", organ "j", and age group "a",

in mrem/pCi, according to the controlling organ and age group; Uaa annual ingestion rate of food in a particular pathway (kilograms/year or liters/year) for individuals in age group "a", according to the controlling age group; and CV(rO) concentration of nuclide "i" at the 1

receptor location (r,O).

3.4.1.c.1 Calculating Vegetation Concentration Factors NUREG-0133 calculations for radioiodines and particulate radionuclides, (except tritium and carbon-14), the concentration factor of nuclide "i" in and on vegetation is estimated as follows:

-xihth CF. = CONST*( r )*e

1 Yv*xi where:

v CF.1 = concentration factor of radionuclide "i" in vegetation (forage, produce, or leafy vegetables), in m2-hr/kg; CONST = 1.14 x 108 number of pCi per Ci (1012) divided by the number of hours per year (8760);

r = is the fraction of deposited activity retained on crops, leafy vegetables, or pasture grass, from airborne radioiodine and particulate deposition:

r = 1.00 for radioiodines r = 0.20 for particulates

Yv V

Y = 2.0 kg/m2 for stored animal s

f = 0.76 for the fraction of produce ingested, grown in garden of interest. (This is f in equation C-13 of g

Regulatory Guide 1.109)

f = 1.00 for the fraction of leafy vegetables grown in garden of interest. (This is f, in equation C-13 of Regulatory Guide 1.109) f = 1.00 for all other pathways 3.4.1.c.2 Concentration Factor for Carbon-14 For carbon-14, the concentration factor in and on vegetation is estimated as follows (see Regulatory Guide 1.109-26, equation C-8):

CFV14 = 2.2 x 10'

p where:

CFV 1 4 = concentration factor of carbon-14 in and on vegetation, in m2-hr/kg; and p = is defined as the ratio of total annual release time (for C-14 atmospheric releases) to the total annual time during which photosynthesis occurs (taken to be 4400 hours0.0509 days 1.222 hours 0.00728 weeks 0.00167 months ), under the condition that the value of "p" should never exceed unity. For continuous C-14 releases, "p" is taken to be unity.

(Thus, the value of 2.2 x 107 is stored for CFV14 in lieu of a site specific value for "p".)

3.4.1.c.3 Concentration Factor for Tritium The concentration factor for tritium in vegetation is calculated from the tritium concentration in air surrounding the vegetation (see Regulatory Guide 1.109-27, equation C-9):

CFTCF = 1.2 x 107 T

H where:

v CFTT concentration factor for tritium in vegetation (in m2-hr/kg); and H = absolute humidity at the location of the vegetation, in g/m3. (The regulatory default value for "H" is 8.0 grams/m3.)

(Thus, the value 1.5 x 106 is stored for CFv in T

lieu of a site specific value for "H"I.)

3.4.1.c.4 Nuclide Concentrations in Produce and Leafy Vegetables The concentrations in and on produce and leafy vegetables of all radioiodine and particulate nulcides "i" (except carbon-14 and tritium) are calculated as follows:

DOQ (r, 0) = relative deposition of the radionuclide "i" at the receptor (r,O)'; and Q.1. release of nuclide "Si" (in curies)

The C-14 and H-3 nuclide concentrations are calculated from the concentration factors times the decayed and depleted radioiodine relative deposition D2DPX/Q times the fraction grown in the garden of interest (f = 0.76, f, = 1.0):

3.4.1.d Nuclide Concentration in Cow's Milk The radionuclide concentration in cow's milk is dependent upon the quantity and contamination level of feed consumed by the animal. The concentration is estimated (see Regulatory Guide 1.109-27, equations C-10 and C-11) as follows:

3.4.1.e Nuclide Concentration in Meat The radionuclide concentration in meat is dependent upon the quantity and contamination level of feed consumed by the animal. The concentration is estimated (see Regulatory Guide 1.109-27, equations

3.5 Gaseous Effluent Projected Dose Calculation 3.5.1 The quarterly projected dose is based upon the methodology of Sections 3.3 and 3.4, and is expressed as follows:

FDQC +DRP DQp = I I

92 L T where:

DQP = Quarterly projected dose (mrem);

DQC = cumulative dose for the quarter (mrem);

D = dose for current release (mrem);

RP T = current days into quarter; and 92 = number of days per quarter.

3.6 Dose to the Public Inside the Site Boundary 3.6.1 Liquid Releases Dose to the public inside the site boundary due to liquid releases will be due to ingestion of fish caught from the discharge canal and exposure to sediment along the discharge canal bank while fishing.

3.6.1.a Dose Due to Ingestion of Fish Dose due to ingestion of fish is calculated using the methodology given in Section 2.2, Liquid Dose Calculation.

3.6.1.b Dose Due to Exposure to Shoreline Sediments Dose from external exposure to shoreline sediments is calculated from equation A-7 of Regulatory Guide 1.109, Rev. 1, 10/77.

U *M *W £ ap p Rapj = 110,000 _

lQi*Ti*Daipj [exp(-1t p)*[1-exp(-,i tb)]

F _

where:

R is the total annual dose to organ "j" of apj individuals of age group "a" from all of the nuclides "i" in pathway in mrem/yr; U ap = is the usage factor that specifies exposure time for the maximum individual of age group "a" in hours from Table E-5 of Regulatory Guide 1.109. 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months for shoreline recreation for a teen was chosen.

Adult is the controlling age group for ingestion but the maximum usage factor (teen) was used rather than the adult factor to ensure a conservative dose estimate; M is the mixing ratio (reciprocal of dilution p

factor);

W is the shoreline width factor from Table A-2 of Regulatory Guide 1.109. The discharge canal value of 0.1 was chosen; F = is the flow rate of the liquid effluent in ft3/sec. This was determined by:

F(ft3/sec) = waste volume (gal/yr) * [134 ft7*721 r hr1* 1 hr-L1galIL 8760 h j00 sej

= is the release of nuclide "i" in Ci/yr; T.1 is the radioactive half-life of nuclide "i", in days, from Radioactive Decay Data Tables, Technical Information Center, U. S.

Dept. of Energy, 1981; Daipj is the dose factor specific to age group "a", nuclide "i", and organ "j" from Table E-6 of Regulatory Guide 1.109; Xi = is the radioactive decay constant of nuclide "i" in hr-1; tp p is the average transit time for nuclides to reach the point of exposure. A value of 0 hours0 days 0 hours 0 weeks 0 months was chosen due to the proximity of the discharge canal to the plant; and tb is the period of time for which sediment is exposed to the contaminated water in hours.

The mid-point of plant operating life, 15 years was chosen per Regulatory Guide 1.109.

3.6.2 Airborne Release 3.6.2.a Dose Due to Noble Gases Dose to fisherman at the discharge canal can be calculated by the ratio of dispersion factor for the discharge canal (1.6E-4 sec/m3 from Table 2-45 SAR, Unit 1, 100 meters downwind in a southerly direction) and the usage factor of 67 hours7.75463e-4 days 0.0186 hours 1.107804e-4 weeks 2.54935e-5 months of shoreline recreation to the values used in Section 3.3 of this manual.

Dose at discharge canal = DlT()*1 1.6E-4 67 hr L2-.1E-6I *8670 hr where DT (0) is the noble gas dose calculated by Section 3.3.

3.6.2.b Dose Due to Iodine, Tritium and Particulates from Gaseous Effluents Section 3.4 calculates total dose for iodine, tritium and particulates as the sum of:

TOT G I V L M F D =D +D +D +D +D +D

where:

G D = ground plane deposition; I

D = inhalation; v

D = consumption of vegetation; L

D = consumption of fresh leafy vegetables; m

D = consumption of milk; and F

D = consumption of meat and poultry; The only contributions relevant to fishing activities at the discharge canal are ground plane deposition and inhalation. As DG and DI are not independently available, a conservative estimate can be obtained by using the same correction factor developed for noble gas dose to the total dose calculated in Section 3.4 for iodine, tritium and particulates. Depletion of the plume as it travels downwind can be ignored since the fraction remaining in the plume at 100 meters (discharge canal) and 1046 meters' (site boundary) are both greater than 90% according to Figure 3 of Regulatory Guide 1.111.

The only activity inside the plant site by members of the public that might contribute a significant dose is fishing along the banks of the discharge canal.

Travel along public roads would involve short exposure time and tours of the facility are conducted according to radiological control procedures enforced at the plant to control exposure. Fishing is the only uncontrolled activity.

LIQUID RADWASTE TREATMENT SYSTEM 1.6 A liquid radwaste treatment system is a system designed and used for holdup, filtration, and/or demineralization of radioactive liquid effluents prior to their release to the environment.

GASEOUS RADWASTE TREATMENT SYSTEM 1.7 A gaseous radwaste treatment system is any system designed and installed to reduce radioactive gaseous effluents by collecting gases from radioactive systems and providing for decay or holdup for the purpose of reducing the total radioactivity prior to release to the environment.

DEFINITIONS VENTILATION EXHAUST TREATMENT SYSTEM 1.8 A ventilation exhaust treatment system is any system designed and installed to reduce gaseous radioiodine or radioactive material in particulate form in effluents by passing ventilation or vent exhaust gases through charcoal adsorbers and/or HEPA filters for the purpose of removing iodines or particulates from the gaseous exhaust stream prior to the release to the environment (such a system is not considered to have any effect on noble gas effluents). Engineered Safety Feature (ESF) atmospheric cleanup systems are not considered to be ventilation exhaust treatment systems.

PURGE - PURGING 1.9 Purge or purging is the controlled process of discharging air or gas from a confinement to reduce the airborne radioactivity concentration in such a manner that replacement air or gas is required to purify the confinement.

MEMBER(S) OF THE PUBLIC 1.10 Member(s) of the public shall include all persons who are not occupationally associated with the plant. This category does not include employees of the utility, its contractors or vendors. Also excluded from the category are persons who enter the site to service equipment or to make deliveries. This category does include persons who use portions of the site for recreational, occupational or other purposes not associated with the plant.

EXCLUSION AREA 1.11 The exclusion area is that area surrounding ANO within a minimum radius of 0.65 miles of the reactor buildings and controlled to the extent necessary by the licensee for purposes of protection of individuals from exposure to radiation and radioactive materials.

BATCH RELEASE 1.14 A "Batch" release is the discharge of liquid wastes of a discrete volume. Prior to sampling for analysis, each batch shall be isolated and then thoroughly mixed to assure representative sampling.

CONTINUOUS RELEASE 1.15 A "Continuous" release is the discharge of liquid waste of a non-discrete volume, e.g. from a volume of a system that has an input flow during the continuous release.

2.0 RELEASE CONTROLS LIMITATION L2.0.1 The Limitation and Action requirements shall be applicable during the conditions specified for each limitation.

L2.0.2 Adherence to the requirements of the Limitation and/or associated Action within the specified time interval shall constitute compliance with the Limitation. In the event the Limitation is restored prior to the expiration of the specified time interval, completion of the action statement is not required.

BASES BL2.0.1 This limitation establishes the general requirements applicable to Limitations. Limitations are the lowest functional capability or performance levels of equipment required for safe operation of the facility. When a Limitation is not met, the licensee shall follow any remedial Action permitted by the Limitation until the condition can be met. This limitation establishes the applicability statement within each individual limitation as the requirement for when (i.e., in which specified conditions) conformance to the Limitation is required for safe operation of the facility. The Action requirements establish those remedial measures that must be taken within specified time limits when the requirements of a Limitation are not met. The Action requirements specify the remedial measures that permit continued operation of the facility which is not further restricted by the time limits of the Action requirements. In this case, conformance to the Action requirements provides an acceptable level of safety for unlimited continued operations as long as the Action requirements continue to be met. The specified time limits of the Action requirements are applicable from the point in time it is identified that a Limitation is not met. The time limits of the Action requirements are also applicable when a system or component is removed from service for surveillance testing or investigation of operational problems. Individual limitations may include a specified time limit for completion of a Surveillance Limitation when equipment is removed from service.

In this case, the allowable outage time limits of the Action requirements are applicable when this limit expires if the surveillance has not been completed.

BL2.0.2 This limitation establishes the general requirements applicable to Limitations. Limitations are the lowest functional capability or performance levels of equipment required for safe operation of the facility. When a limitation is not met, the licensee shall follow any remedial Action permitted by the Limitation until the condition can be met. This limitation establishes that noncompliance with a limitation exists when the requirements of the Limitation are not met and the associated Action requirements have not been implemented within the specified time interval. The purpose of this limitation is to clarify that (1) implementation of the Action requirements constitutes compliance with a limitation and (2) completion of the remedial measures of the Action requirements is not required when compliance with a Limitation is restored within the time interval specified in the associated Action requirements.

SURVEILLANCE LIMITATION S2.0.1 Surveillance Limitations shall be applicable during the conditions specified for individual Limitations unless otherwise stated in an individual Surveillance Limitation.

S2.0.2 Each Surveillance Limitation shall be performed within the specified surveillance interval with a maximum allowable extension not to exceed 25% of the specified surveillance interval.

BASES BS2.0.1 This surveillance limitation establishes the general requirements applicable to Surveillance Limitations. Surveillance Limitations are requirements relating to test, calibration, or inspection to ensure that the necessary quality of systems and components is maintained and that the limitations will be met. This surveillance limitation establishes the requirement that surveillances must be performed during the conditions for which the requirements of the Limitation apply unless otherwise stated in an individual Surveillance Limitation. The purpose of this surveillance limitation is to ensure that the surveillances are performed to verify the operational status of systems and components and that parameters are within specified limits to ensure safe operation of the facility when the plant is an a specified condition for which the associated Limitations are applicable. Surveillance Limitations do not have to be performed when the facility is in a condition for which the requirements of the associated Limitation do not apply unless otherwise specified.

BS2.0.2 This surveillance limitation establishes the general requirements applicable to Surveillance Limitations. Surveillance Limitations are requirements relating to test, calibration, or inspection to ensure that the necessary quality of systems and components is maintained and that the limitations will be met. This surveillance limitation establishes the limit for which the specified time interval for Surveillance Limitations may be extended.

It permits an allowable extension of the normal surveillance interval to facilitate surveillance scheduling and consideration of plant operating conditions that may not be suitable for conducting the surveillance (e.g.,

transient conditions or other ongoing surveillance or maintenance activities).

It also provides flexibility to accommodate the length of a fuel cycle for surveillances that are performed at a refueling frequency and are specified with an 18-month surveillance interval. It is not intended that this provision be used repeatedly as a convenience to extend surveillance intervals beyond that specified for surveillances. This surveillance limitation is based upon engineering judgement and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the Surveillance Limitations. This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance intervals.

2.1 RADIOACTIVE LIQUID EFFLUENT MONITORING INSTRUMENTATION LIMITATION L2.1.1 The radioactive liquid effluent monitoring instrumentation shown in Table 2.1-1 shall be operable with their alarm/trip setpoints set to ensure that the limits of Appendix 1, Limitation L2.3.I.A are not exceeded.

RELEASE CONTROLS RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION BASES BL2.2.1 The radioactive gaseous effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous effluents during actual or potential releases. The alarm/trip setpoints for these instruments shall be calculated in accordance with methods in this manual to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20.105.

BS2.2.1 To ensure that the instrumentation for the gaseous radwaste system is operable.

The channel test demonstrates that control room alarm annunciation occurs if any of the following conditions exist:

TABLE NOTATION

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.

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

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

f. If continuous samples cannot be obtained, then grab samples shall be collected and analyzed at least 1/24 hrs when the specific activity of the secondary coolant is *0.01 pCi/ml IDE (1-131) or at least 1/12 hrs when the specific activity of the secondary coolant is >0.01 pCi/ml IDE (1-131). Grab sample frequency may be increased due to plant conditions.

g. The principal gamma emitters for which the LLD limitation 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 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 Radioactive Effluent Release Report.

h. 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 analysis, all samples taken for the composite shall be thoroughly mixed in order for the composite sample to be reperesentative of the effluent release.

ACTION:

1. With the calculated dose from radioactive noble gases in gaseous effluents exceeding any of the above limits, in lieu of any other report, prepare and submit a Special Report to the Commission within 30 days, pursuant to Appendix 1, Section 3.4 Limitations.

BASES BL2.4.2.A Limitation L2.4.2.A implements the design guides specified in 10 CFR 50, Appendix I, Section II, and the limiting condition for operation as set forth in Section IV.A of Appendix I.

The limitations provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A, Appendix I, to assure that the releases of radioactive material in gaseous effluents will be kept "as low as is reasonably achievable."

These limits provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of an individual in an unrestricted area, to annual average concentrations exceeding the limits specified in Appendix B, Table II of 10 CFR Part 20

[10 CFR Part 20.106(b)]. For individuals who may at times be within the exclusion area boundary, the occupancy of the individual will be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the exclusion area boundary.

BASES BL2.4.3.A Limitation L2.4.3.A 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.

This limitation provides 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".

RELEASE CONTROLS RADIOACTIVE GASEOUS EFFLUENTS 2.4.4 Gaseous Radwaste Treatment LIMITATIONS L2.4.4.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 effluent releases from ANO-l to unrestricted areas (see Figure 4-2) would exceed 0.625 mrad for gamma radiation and 1.25 mrad for beta radiation over a calendar quarter; or when the projected doses 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.

L2.4.4.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 radioactive materials prior to discharge when the projected doses due to gaseous effluent releases from ANO-I to unrestricted areas (see Figure 4-2) would exceed 0.625 mrad for gamma radiation and 1.25 mrad for beta radiation over a calendar quarter.

APPLICABILITY: At all times OBJECTIVE: To assure that the amount of radioactive material in gaseous effluents is "as low as reasonably achievable."

ACTION:

1. With gaseous waste being discharged without treatment and in excess of the above limits, in lieu of any other report, prepare and submit to the Commission within 30 days a Special Report, per Appendix 1, Section 3.4 Limitations.

a BASES BL2.4.4.A/B 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 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 I, 10 CFR Part 50, for gaseous effluents. The values 0.625 mrad, 1.25 mrad, and 1.0 mrem are approximately 25% of the yearly design objectives on a quarterly basis. The yearly design objectives are given in Appendix 1, Limitations L2.4.2.A and L2.4.3.A.

RELEASE CONTROLS 2.5 RADIOACTIVE EFFLUENTS 2.5.1 Total Dose LIMITATIONS L2.5.I.A The calculated doses from the release of radioactive materials in liquid or gaseous effluents shall not exceed twice the limits of Appendix 1, Limitation L2.3.2.A, L2.4.2.A, or L2.4.3.A.

APPLICABILITY: At all times OBJECTIVE: To ensure that the limits of 40 CFR 190 are not exceeded.

ACTION:

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

2. If the limits of 40 CFR 190 have been exceeded, obtain a variance from the Commission to permit further releases in excess of 40 CFR 190 limits. A variance is granted until staff action on the request is completed.

SURVEILLANCE LIMITATION

$2.5.1.A Cumulative dose contributions and dose projections for liquid effluents and for gaseous effluents shall be determined in accordance with this manual at least once per 31 days.

APPLICABILITY: At all times OBJECTIVE: To ensure that the requirements of 10 CFR 50, Appendix I, Section III.A are met.

RELEASE CONTROLS RADIOACTIVE EFFLUENTS Total Dose BASES BL2.5.1.A This limitation is provided to meet the dose limits of 40 CFR 190 that have now been incorporated into 10 CFR Part 20. The limitation requires the preparation and submittal of a Special Report whenever 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 Report will describe a course of action that should result in limiting 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 fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities 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 40 CFR 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR 190 have not already been corrected), in accordance 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 limits in 10 CFR 20, as addressed in Appendix 1, Section 2.3 & 2.4 Limitations. 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 operation that is part of the nuclear fuel cycle.

BS2.5.I.A These calculations provide the dose values to be compared to the limits of Appendix 1, Limitations L2.3.2.A, L2.3.3.A, L2.4.2.A, L2.4.3.A, L2.4.4.A, and L2.5.I.A.

APPLICABILITY: Applies at all times.

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

BASES BL2.6.I.A & BS2.6.I.A The radiological monitoring program required by this limitation 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 concentrations 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.

110 DEFINITIONS OPERABLE - OPERABILITY 1.1 A system, subsystem, train, component or device shall be operable or have operability when it is capable of performing its specified function(s). Implicit in this definition shall be the assumption that all necessary attendant instrumentation, controls, normal and emergency electrical power sources, cooling or seal water, lubrication or other auxiliary equipment that are required for the system, subsystem, train, component or device to perform its function(s) are also capable of performing their related support function(s).

CHANNEL CALIBRATION 1.2 A channel calibration shall be the adjustment, as necessary, of the channel output such that it responds with the necessary range and accuracy to known values of the parameter which the channel monitors. The channel calibration shall encompass the entire channel including the sensor and alarm and/or trip functions, and shall include the channel functional test. The channel calibration may be performed by any series of sequential, overlapping or total channel steps such that the entire channel is calibrated.

CHANNEL CHECK 1.3 A channel check shall be the qualitative assessment of channel behavior during operation by observation. This determination shall include, where possible, comparison of the channel indication and/or status with other indications and/or status derived from independent instrument channels measuring the same parameter.

CHANNEL FUNCTIONAL TEST 1.4 A channel functional test shall be:

a. Analog channels - The injection of a simulated signal into the channel as close to the sensor as practicable to verify operability including alarm and/or trip functions.

b. Bistable channels - The injection of a simulated signal into the sensor to verify operability including alarm and/or trip functions.

c. Digital computer channels - The exercising of the digital computer hardware using diagnostic programs and the injection of simulated process data into the channel to verify operability.

SOURCE CHECK 1.5 A source check shall be the qualitative assessment of channel response when the channel sensor is exposed to the radioactive source.

DEFINITIONS LIQUID RADWASTE TREATMENT SYSTEM 1.6 A liquid radwaste treatment system is a system designed and installed to reduce radioactive liquid effluents from the unit. This is accomplished by providing for holdup, filtration, and/or demineralization of radioactive liquid effluents prior to their release to the environment.

GASEOUS RADWASTE TREATMENT SYSTEM 1.7 A gaseous radwaste treatment system is any system designed and installed to reduce radioactive gaseous effluents from the plant by collecting offgases from radioactive systems and providing for decay or holdup for the purpose of reducing the total radioactivity prior to release to the environment.

VENTILATION EXHAUST TREATMENT SYSTEM 1.8 A ventilation exhaust treatment system is any system designed and installed to reduce gaseous radioiodine or radioactive material in particulate form in effluents by passing ventilation or vent exhaust gases through charcoal adsorbers and/or HEPA filters for the purpose of removing iodines or particulates from the gaseous exhaust stream prior to the release to the environment. Such a system is not considered to have any effect on noble gas effluents. Atmospheric cleanup systems that are Engineered Safety Feature (ESF) actuated are not considered to be ventilation exhaust treatment systems.

MEMBER(S) OF THE PUBLIC 1.9 Member(s) of the public shall include all persons who are not occupationally associated with the plant. This category does not include employees of the utility, its contractors or vendors. Also excluded from this category are persons who enter the site to service equipment or to make deliveries.

2.0 RELEASE CONTROLS LIMITATION L2.0.1 The Limitation and Action requirements shall be applicable during the conditions specified for each limitation.

L2.0.2 Adherence to the requirements of the Limitation and/or associated Action within the specified time interval shall constitute compliance with the Limitation. In the event the Limitation is restored prior to the expiration of the specified time interval, completion of the action statement is not required.

BASES BL2.0.1 This limitation establishes the general requirements applicable to Limitations. Limitations are the lowest functional capability or performance levels of equipment required for safe operation of the facility. When a Limitation is not met, the licensee shall follow any remedial Action permitted by the Limitation until the condition can be met. This limitation establishes the applicability statement within each individual limitation as the requirement for when (i.e., in which specified conditions) conformance to the Limitation is required for safe operation of the facility. The Action requirements establish those remedial measures that must be taken within specified time limits when the requirements of a Limitation are not met. The Action requirements specify the remedial measures that permit continued operation of the facility which is not further restricted by the time limits of the Action requirements. In this case, conformance to the Action requirements provides an acceptable level of safety for unlimited continued operations as long as the Action requirements continue to be met. The specified time limits of the Action requirements are applicable from the point in time it is identified that a Limitation is not met. The time limits of the Action requirements are also applicable when a system or component is removed from service for surveillance testing or investigation of operational problems. Individual limitations may include a specified time limit for completion of a Surveillance Limitation when equipment is removed from service.

In this case, the allowable outage time limits of the Action requirements are applicable when this limit expires if the surveillance has not been completed.

BL2.0.2 This limitation establishes the general requirements applicable to Limitations. Limitations are the lowest functional capability or performance levels of equipment required for safe operation of the facility. When a limitation is not met, the licensee shall follow any remedial Action permitted by the Limitation until the condition can be met. This limitation establishes that noncompliance with a limitation exists when the requirements of the Limitation are not met and the associated Action requirements have not been implemented within the specified time interval. The purpose of this limitation is to clarify that (1) implementation of the Action requirements constitutes compliance with a limitation and (2) completion of the remedial measures of the Action requirements is not required when compliance with a Limitation is restored within the time interval specified in the associated Action requirements.

SURVEILLANCE LIMITATION S2.0.1 Surveillance Limitations shall be applicable during the conditions specified for individual Limitations unless otherwise stated in an individual Surveillance Limitation.

S2.0.2 Each Surveillance Limitation shall be performed within the specified surveillance interval with a maximum allowable extension not to exceed 25% of the specified surveillance interval.

BASES BS2.0.1 This surveillance limitation establishes the general requirements applicable to Surveillance Limitations. Surveillance Limitations are requirements relating to test, calibration, or inspection to ensure that the necessary quality of systems and components is maintained and that the limitations will be met. This surveillance limitation establishes the requirement that surveillances must be performed during the conditions for which the requirements of the Limitation apply unless otherwise stated in an individual Surveillance Limitation. The purpose of this surveillance limitation is to ensure that the surveillances are performed to verify the operational status of systems and components and that parameters are within specified limits to ensure safe operation of the facility when the plant is an a specified condition for which the associated Limitations are applicable. Surveillance Limitations do not have to be performed when the facility is in a condition for which the requirements of the associated Limitation do not apply unless otherwise specified.

BS2.0.2 This surveillance limitation establishes the general requirements applicable to Surveillance Limitations. Surveillance Limitations are requirements relating to test, calibration, or inspection to ensure that the necessary quality of systems and components is maintained and that the limitations will be met. This surveillance limitation establishes the limit for which the specified time interval for Surveillance Limitations may be extended.

It permits an allowable extension of the normal surveillance interval to facilitate surveillance scheduling and consideration of plant operating conditions that may not be suitable for conducting the surveillance (e.g.,

transient conditions or other ongoing surveillance or maintenance activities).

It also provides flexibility to accommodate the length of a fuel cycle for surveillances that are performed at a refueling frequency and are specified with an 18-month surveillance interval. It is not intended that this provision be used repeatedly as a convenience to extend surveillance intervals beyond that specified for surveillances. This surveillance limitation is based upon engineering judgement and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the Surveillance Limitations. This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance intervals.

Unit 2 RELEASE CONTROLS RADIOACTIVE LIQUID EFFLUENT MONITORING INSTRUMENTATION BASES BL2.1.1 & BS2.1.1 The radioactive liquid effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in liquid effluents during actual or potential releases of liquid effluents. The alarm/trip setpoints for these instruments shall be calculated in accordance with the procedures in this manual to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20.

For the radioactive liquid effluent instrumentation surveillance requirements, the channel test demonstrates that automatic isolation of this pathway and control room alarm annunciation occur if the instrument indicates measured levels above the trip setpoint. The channel test demonstrates that alarm annunciation occurs if any of the following conditions exist:

A. Power to the detector is lost.

B. The instrument indicates a downscale failure (local alarm only on 2RE-4423).

The initial channel calibration is performed using one or more of the reference standards certified by the National Institute of Standards and Technology or using standards that have been obtained from suppliers that participate in measurement assurance activities with NIST. These standards permit calibrating the system over its intended range of energy and measurement range. For subsequent channel calibration, sources that have been related to the initial calibration are used.

Unit 2 RELEASE CONTROLS RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION BASES BL2.2.1 & BS2.2.1 The radioactive gaseous effluent 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 setpoints for these instruments shall be calculated in accordance with the procedures in this manual to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20.

For the radioactive gaseous effluent instrumentation surveillance requirements, the channel functional test demonstrates that control room alarm annunciation occurs if any of the following conditions exist:

A. The instrument indicates measured levels above the alarm/trip setpoint.

B. Power to the detector is lost.

C. The instrument indicates a downscale failure.

For the containment purge and the waste gas holdup system noble gas activity monitors, the channel functional test also demonstrates the automatic isolation of the release pathway occurs if the instrument indicates above the trip setpoint.

The initial channel calibration is performed using one or more of the reference standards certified by the National Institute of Standards and Technology or using standards that have been obtained from suppliers that participate in measurement assurance activities with NIST. These standards permit calibrating the system over its intended range of energy and measurement range. For subsequent channel calibration, sources that have been related to the initial calibration are used.

Unit 2 RELEASE CONTROLS 2.3 RADIOACTIVE LIQUID EFFLUENTS 2.3.1 Concentration LIMITATION L2.3.l.A The concentration of radioactive material released from the site in liquid effluents to the discharge canal shall be limited to the concentrations specified in 10 CFR Part 20, Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration released shall be limited to 2 x 104 PCi/ml.

APPLICABILITY: At all times.

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.

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

f. If continuous samples cannot be obtained, then grab samples shall be collected and analyzed at least 1/24 hrs when the specific activity of the secondary coolant is *0.01 pCi/ml IDE (1-131) or at least 1/12 hrs when the specific activity of the secondary coolant is >0.01 PCi/ml IDE (1-131). Grab sample frequency may be increased due to plant conditions.

g. The principal gamma emitters for which the LLD limitation 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 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 Radioactive Effluent Release Report.

h. 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 analysis, all samples taken for the composite shall be thoroughly mixed in order for the composite sample to be reperesentative of the effluent release.

Unit 2 RELEASE CONTROLS RADIOACTIVE LIQUID EFFLUENTS Concentration BASES BL2.3.I.A & BS2.3.I.A This limitation is provided to ensure that the concentration of radioactive materials released in liquid waste effluents in unrestricted areas will be less than the concentration levels specified in 10 CFR Part 20, Appendix B, Table II, Column 2. This limit provides additional assurance that the levels of radioactive materials in bodies of water in unrestricted areas will result in exposures within (1) the Section II.A

'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 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.

Unit 2 RELEASE CONTROLS RADIOACTIVE LIQUID EFFLUENTS 2.3.2 Dose LIMITATION L2.3.2.A The dose commitment to a member of the public from radioactive materials in liquid effluents released from ANO-2 to the discharge canal shall be limited:

BASES BL2.3.2.A & BS2.3.2.A This limitation provides assurance that releases of liquid effluents will result in concentrations below the limits of 10 CFR 20.

The limitation provides the required operating flexibility and at the same time assures that the release of radioactive material in liquid effluents will be kept "as low as is reasonably achievable." The equations specified in this manual for calculating the doses due to the actual release rates of radioactive materials in liquid effluents 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 1, October 1977, and Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I", April 1977.

BASES BL2.3.3.A & BS2.3.3.A 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 liquid radwaste treatment system were specified as a suitable fraction of the dose design objectives set forth in Section II.A of Appendix I, 10 CFR Part 50, for liquid effluents.

The values of 0.18 mrem and 0.625 mrem are approximately 25% of the yearly design objectives on a quarterly basis. The yearly design objectives are given in 10 CFR 50, Appendix I, Section II.

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 reasonably achievable." The Surveillance Limitations 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 dose calculations established in this manual for calculating the doses due to the actual release rates of radioactive noble gases in gaseous effluents 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 1, 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.

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 calculational methods in this manual specified in the Surveillance Limitations 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 calculational methods in this manual 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 1, 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 atmospheric conditions. The release rate limitations for iodine-131, tritium, and radionuclides in particulate form with half-lives greater than 8 days are dependent on the existing radionuclide pathways to man in the areas at or beyond the site boundary.

The pathways 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.

Unit 2 RELEASE CONTROLS RADIOACTIVE EFFLUENTS Total Dose BASES BL2.5.l.A & BS2.5.I.A This limitation is provided to meet the dose limits of 40 CFR Part 190 that have now been incorporated into 10 CFR Part 20 by 46 FR 18525. The limitation requires the preparation and submittal of a Special Report whenever the calculated doses from plant radioactive effluents exceed twice the design objective doses of Appendix I. 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 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 limiting 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 requirements 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 provision of 40 CFR Part 190.11 and 10 CFR Part 20.405c, is considered 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 limits in 10 CFR Part 20, as addressed in Appendix 2, Section 2.3 and 2.4 Limitations. 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.

TABLE NOTATION a The ODCM shall include, in a table and figures, specific parameters of distance and direction from the centerline of one reactor, and additional description where pertinent, for each sample location in Table 2.6-1. Refer to NUREG-0133, "Preparation of Radiological Technical Specifications for Nuclear Power Plants," October 1978, and to Radiological Assessment Branch Technical Position, Revision 1, November 1979. Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons. If specimens are unobtainable due to sampling equipment malfunctions, every effort shall be made to complete corrective action before the end of the next sampling period. All deviations from the sampling schedule shall be documented in the Annual Radiological Environmental Operating Report.

It is recognized that, at times, it may not be possible or practical to continue to obtain samples of the media of choice at the most desirable location or time. In these instances, suitable alternative media and locations may be chosen for the particular pathway in question and appropriate substitutions made within 30 days in the radiological environmental monitoring program. In the next Annual Radioactive Effluent Release Report, identify the cause of the unavailability of samples for that pathway and identify the new location(s) for obtaining replacement samples, and also include in the report a revised figure(s) and table(s) for the ODCM reflecting the new location(s).

Unit 2 RELEASE CONTROLS RADIOLOGICAL ENVIRONMENTAL MONITORING Monitoring Program SURVEILLANCE LIMITATIONS S2.6.1.A. The results of analyses performed on the radiological environmental monitoring samples shall be summarized in the Annual Radiological Environmental Operating Report.

BASES BL2.6.I.A & BS2.6.I.A The radiological monitoring program required by this limitation 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 concentrations 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 2.6-2 are state of the art for routine environmental measurements in industrial laboratories.

Unit 2 RELEASE CONTROLS RADIOLOGICAL ENVIRONMENTAL MONITORING 2.6.2 Land Use Census LIMITATION L2.6.2.A 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.

APPLICABILITY: At all times.

ACTION:

1. With a land use census identifying a location(s) which yields a calculated dose commitment due to 1-131, tritium, and radionuclides in particulate form greater than the values currently being calculated in Appendix 2, Limitation S2.4.3.A, submit location description in the Radioactive Effluent Release Report per Appendix 2, Section 3.2 Limitations.

2. With a land use census identifying a location(s) which yields a calculated dose commitment (via the sample exposure pathway) greater than at a location from which samples are currently being obtained in accordance with the Appendix 2, Limitation L2.6.l.A, identify the new location in the Radioactive Effluent Release Report per Appendix 2, Section 3.2 Limitations. The new location shall be added to the radiological 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 conducted.

SURVEILLANCE LIMITATIONS

$2.6.2.A The land use census shall be conducted at least once per 24 months between the dates of June 1 and October 1 by door-to-door survey, aerial survey, or by consulting local agricultural authorities. The results of the land use census shall be included in the Annual Radiological Environmental Operating Report.

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.

Unit 2 RELEASE CONTROLS RADIOLOGICAL ENVIRONMENTAL MONITORING Land Use Census BASES BL2.6.2.A & BS2.6.2.A This limitation 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 (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.

IUnit 2 RELEASE CONTROLS RADIOLOGICAL ENVIRONMENTAL MONITORING 2.6.3 Interlaboratory Comparison Program LIMITATION L2.6.3.A Analyses shall be performed on radioactive materials supplied as part of the Interlaboratory Comparison Program which has been approved by NRC.

APPLICABILITY: At all times.

ACTION:

1. With analyses not being performed as required above, report the corrective actions taken to prevent a recurrence to the Commission in the Annual Radiological Environmental Operating Report.

SURVEILLANCE LIMITATIONS S2.6.3.A The results of analyses performed as part of the above required Interlaboratory Comparison Program shall be included in the Annual Radiological Environmental Operating Report.

BASES BL2.6.3.A & BS2.6.3.A 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.

1.0 PURPOSE The Process Control Program (PCP) requires formulas, sampling, analyses, test and determinations to be made to ensure that the processing and packing of solid radioactive wastes based on demonstrated processing of actual or simulated wet solid wastes will be accomplished in such a way as to assure compliance with 10 CFR Parts 20, 61 and 71, State Regulations, burial ground requirements, and other requirements governing the disposal of solid radioactive waste. The scope of a PCP is to assure that radioactive waste will be handled, shipped, and disposed of in a safe manner in accordance with approved site or vendor procedures, whichever is applicable. [GGNS UFSAR, Chapter 16B.1 1 TRM - 7.6.3.8 paragraph 1]

EN-RW-105 implements the requirements of 10CFR Part 50.36a and General Design Criteria 60 of Appendix A to 10CFR Part 50. The process parameters included in the Process Control Program may include but are not limited to waste type, waste pH, waste/liquid/solidification agent/catalyst ratios, waste oil content, waste principal chemical constituents, and mixing and curing times.
