| | |
| SECTION I. RADIOLOGICAL EFFLUENT MONITORING MANUAL (REMM)
| |
| I.A Introduction The purpose of Section I of this manual is to provide the sampling and analysis programs which provide input to Section II for calculating liquid and gaseous effluent concentrations and offsite doses. Guidelines are provided for operating radioactive waste treatment systems in order that offsite doses are kept As-Low-As-Reasonably-Achievable (ALARA).
| |
| The Radiological Environmental Monitoring Program outlined within this manual provides confirmation that the measurable concentrations of radioactive material in the environment as a result of operations at the Millstone Site are not higher than expected.
| |
| In addition, this manual outlines the information required to be submitted to the NRC in both the Annual Radiological Environmental Operating Report and the Radioactive Effluent Release Report.
| |
| MP-22-REC-REF03, "REMODCM Technical Information Document (TID)," has additional bases and technical information. It also contains a list of exceptions to Regulatory Guide 1.21 (see Section 2 of the TID).
| |
| I.B. Responsibilities All changes to the Radiological Effluent Monitoring Manual (REMM) shall be reviewed and approved by the Facility Safety Review Committee prior to implementation.
| |
| All changes and their rationale shall be documented in the Radioactive Effluent Release Report.
| |
| It shall be the responsibility of the Site Vice President Millstone to ensure that this manual is used as required by the administrative controls of the Technical Specifications. The delegation of implementation responsibilities is delineated in MP-22-REC-PRG, "Radiological Effluent Program."
| |
| I.C. Liquid Effluents
| |
| : 1. Liquid Effluent Sampling and Analysis Program Radioactive liquid wastes shall be sampled and analyzed in accordance with the program specified in Table I.C.-1 for Millstone Unit No. 1, Table I.C.-2 for Millstone Unit No. 2, and Table I.C.-3 for Millstone Unit No. 3. The results of the radioactive analyses shall be input to the methodology of Section II to assure that the concentrations at the point of release are maintained within the limits of Radiological Effluent Controls (Section III.D.l.a. for Millstone Unit No. 1, Section IVD.l.a. for Millstone Unit No.
| |
| 2, and Section VD.La. for Millstone Unit No. 3).

| |
| LLD= 4.66 Sb (E )(V)(2.22xl0 6)(Ye-AL1~
| |
| Where :
| |
| * LLD is the lower limit of detection as defined above (as µCi per unit mass or volume)
| |
| * Sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)
| |
| * E is the counting efficiency (as counts per transformation)
| |
| * V is the sample size (in units of mass or volume)

| * 2.22 x 10 6 is the number of transformations per minute per µCi
| |
| * Y is the fractional radiochemical yield (when applicable)
| |
| * "' is the radioactive decay constant for the particular radionuclide
| |
| * Lit is the elapsed time between midpoint of sample collection and midpoint of counting time It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement.

| |
| | |
| Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions . Occasionally background fluctuations, unavoidably small sample sizes , the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases , the contributing factors will be identified and recorded on the analysis sheet for the particular sample.
| |
| B. Prior to the sampling , each batch shall be isolated and at least two tank/sump volumes shall be recirculated or equivalent mixing provided.
| |
| 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. Prior to analysis , all samples taken for the composite shall be thoroughly mixed in order for the composite sample to be representative of the effluents released.
| |
| D. For sources with no release during previous quarter, a quarterly sample is not required.

| B. A batch release is the discharge of liquid wastes of a discrete volume from the tanks listed in this table. Prior to the sampl ing, each batch shall be isolated and at least two tank/sump volumes shall be recirculated or equivalent mixing provided. If the steam generator bulk can not be recirculated prior to batch discharge, a sample will be obtained by representative compositing during discharge.
| |
| C. The LLD will be 5 x 1o- 7 µCi/ml. The principal gamma emitters for which this LLD applies are exclusively the following rad ionuclides : Mn - 54, Fe - 59, Co-58 , Co - 60 , Zn - 65, Mo-99, Cs - 134, Cs - 137, and Ce - 141. Ce-144 shall also be measured , but with an LLD of 5 x 10- 6
| |
| µCi/ml. This list does not mean that only these nuclides are to be detected and reported.
| |

| H. Waste Gas Storage Tanks are normally released on a batch basis via the Millstone Stack.
| |
| However, for the purpose of tank maintenance, inspection, or reduction of oxygen concentration , a waste gas tank may be vented or purged with nitrogen and released to the environment via the normal or alternate pathway using one of the following methods:
| |
| Method A: Without a permit provided the following conditions are met:
| |
| (1) The tank has been previously discharged with a permit.
| |
| (2) The current tank pressure is less than 5 PSIG .
| |
| (3) No radioactive gases have been added to the tank since the previous discharge from the tank.
| |
| (4) Valve lineups are verified to ensure that no radioactive waste gases will be added to the tank.
| |
| (5) Prior to initiation of the vent or purge, a sample of the gas in the tank will be taken and analyzed for any residual gamma emitters and tritium. The tank may be released if:
| |
| a) Tank radioactivity is less than 1% of the radioactivity released in the previous batch release from the tank, or less than 1% of the radioactivity released to date for the calendar year, and b) the radioactivity of Kr-85 and Xe-133 is less than 0.01 Ci and the radioactivity of all other gases is less than 0.001 Ci.
| |
| Method B: With a permit provided valve lineups are verified to ensure that no radioactive waste gases will be added to the tank.
| |
| I. IE compared to the radioactivity at the time of the air sample, a Radiation Monitor RM8123 or RM8262 gas channel increases by a factor of two, THEN a new containment air sample shall be taken.
| |
| IE containment noble gas radioactivity exceeds 1E-6 µCi/cc as indicated by the last grab sample, THEN sampling frequency shall be increased to weekly until such time that the radioactivity is less than 1E-6 µCi/cc.
| |
| J. During an outage a sample is only required prior to the initial purge.

| I.E. Radiological Environmental Monitoring
| |
| : 1. Sampling and Analysis The radiological sampling and analyses provide 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 plant operation. This monitoring program thereby supplements the radiological effluent 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.
| |
| Program changes may be made based on operational experience.
| |
| The sampling and analyses shall be conducted as specified in Table I.E. -1 for the locations shown Table I.E.-2. Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment or other legitimate reasons. If specimens are unobtainable due to sampling equipment malfunction, every effort shall be made to complete corrective action prior to the end of the next sampling period.
| |
| All deviations from the sampling schedule shall be documented in the Annual Radiological Environmental Operating Report pursuant to Section I.F.l. It is recognized that, at times, it may not be possible or practicable to obtain samples of the media of choice at the most desired 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. Any of the above occurrences shall be documented in the Annual Radiological Environmental Operating Report, which is submitted to the U . S. Nuclear Regulatory Commission prior to May 1 of each year.
| |
| If the level of radioactivity in an environmental sampling medium at one or more of the locations specified in Table I.E. -2 exceeds the report levels of Table I.E. -3 when averaged over any calendar quarter, prepare and submit to the Commission within 30 days from receipt of sample results, a Special Report which includes an evaluation of any release conditions, environmental factors or other aspects which caused the limits of Table I.E.-3 to be exceeded. When more than one of the radionuclides in Table I.E.-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)
| |
| MP-22-REC-BAPOl STOP TH INK ACT REVIEW Rev. 029 36 of 137
| |
| | |
| When radionuclides other than those in Table I.E.-3 are detected and are the result of plant effluents, this report shall be submitted if the potential annual dose to an individual is equal to or greater than the appropriate calendar year limit of the Radiological Effluent Controls (Sections III.D.l.b.,
| |
| III.D.2.b., or III.D.2.c. for Unit 1; Sections IV.D.l.b., IV.D.2.b. , or IV.D.2.c.
| |
| for Unit 2; and Sections V.D.l.b. , V.D.2.b., or V.D.2.c. for Unit 3). This report is not required if the measured level of radioactivity was not the result of plant effluents, however, in such an event, the condition shall be reported and described in the Annual Radiological Environmental Operating Report.
| |
| The detection capabilities required by Table I.E.-4 are state-of-the-art for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement. All analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors will be identified and described in the Annual Radiological Environmental Operating Report.

| SECTION IL OFFSITE DOSE CALCULATION MANUAL (ODCM)
| |
| II.A. Introduction The purpose of the Offsite Dose Calculation Manual (Section II of the REMODCM) is to provide the parameters and methods to be used in calculating offsite doses and effluent monitor setpoints at the Millstone Nuclear Power Station. Included are methods for determining maximum individual whole body and organ doses due to liquid and gaseous effluents to assure compliance with the regulatory dose limitations in 10 CFR 50, Appendix I. Also included are methods for performing dose projections to assure compliance with the liquid and gaseous treatment system functionality sections of the Radiological Effluent Monitoring Manual (REMM - Section I of the REMODCM). The manual also includes the methods used for determining quarterly and annual doses for inclusion in the Radioactive Effluent Release Report.
| |
| The bases for selected site-specific factors used in the dose calculation methodology are provided in MP-22-REC-REF03, "REMODCM Technical Information."
| |
| Another section of this manual discusses the methods to be used in determining effluent monitor alarm/trip setpoints to be used to ensure compliance with the instantaneous release rate limits in Sections III.D.2.a., IV.D.2.a., and V.D.2.a.
| |
| This manual includes the methods to be used in performance of the surveillance requirements in the Radiological Effluent Controls of Sections III, IV, and V.
| |
| Appendix A, Tables App.A-1 provide a cross-reference of effluent requirements and applicable methodologies contained in the REMODCM.
| |
| II.B. Responsibilities All changes to the Offsite Dose Calculation Manual (ODCM) shall be reviewed and approved by the Facilities Safety Review Committee prior to implementation.
| |
| All changes and their rationale shall be documented in the Radioactive Effluent Release Report.
| |
| It shall be the responsibility of the Site Vice President Millstone to ensure that this manual is used as required by the administrative controls of the Technical Specifications. The delegation of implementation responsibilities is delineated in the MP-22-REC-PRG, "Radiological Effluent Control."

| |
| | |
| II.C. Liquid Dose Calculations Radiological Effluent Controls (Sections III, IV, and V) limit whole body and maximum organ doses to an individual member of the public to 1.5 mrem whole body and 5 mrem maximum organ per calendar quarter and 3 mrem whole body and 10 mrem maximum organ per year from liquid effluents released from each unit. (See Appendix A, Table App.A-1 for cross-reference effluent control requirements and applicable sections in the REMO DCM which are used to determine compliance). In addition, installed portions of liquid radwaste treatment system are required to be operated to reduce radioactive materials in liquid effluents when the projected dose over 31 days from applicable waste streams exceeds 0.006 mrem whole body or 0.02 mrem maximum organ. This part of the REMODCM provides the calculation methodology for determining the doses from radioactive materials released into liquid pathways of exposure associated with routine discharges.
| |
| : 1. Monthly, Quarterly, and Annual Dose Calculation (Applicable to All Units)
| |
| For each Unit, whole body and maximum organ doses from liquid effluents shall be calculated at least once per 31 days (or monthly) using the methodology of Regulatory Guide 1.109, Rev. 1. The calculation shall include contributions from all analyses required by Table I.C-1 for Unit 1, Table I.C-2 for Unit 2, and Table I.C-3 for Unit 3 recorded to date. If any required analyses have not yet been completed for the dose period, an estimate of dose from unanalyzed isotopes shall be included in the dose total.
| |
| Results of these dose calculations shall be summed to determine compliance with quarterly and annual dose limits for each Unit.
| |
| : 2. Monthly Dose Projections Section I.C.2.a. of the REMM requires that certain portions of the liquid radwaste treatment equipment be used to reduce radioactive liquid effluents when the projected doses for each Unit (made at least once per 31 days) exceeds 0.006 mrem whole body or 0.02 mrem to any organ. The following methods are applied in the estimation of monthly dose projections:
| |
| : a. Whole Body and Maximum Organ when Steam Generator Total Gamma Radioactivity is less than SE- 7 µCi /ml and Steam Generator Tritium is less than 0.02 µCi/ml (Applicable to Units 2 and 3)
| |
| The projected monthly whole body dose (Units 2 or 3) is determined from:
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 52 of 137
| |
| | |
| The monthly projected maximum organ dose (Units 2 or 3) is determined from:
| |
| Where:
| |
| DMW = the whole body dose from the last typical previously completed month as calculated per the methods in Section II.C.l.
| |
| DMo = the maximum organ dose from the last typical previously completed month as calculated per the methods in Section IL C. l.
| |
| R1 = the ratio of the total estimated volume of liquid batches to be released in the present month to the volume released in the past month.
| |
| Ri = the ratio of estimated primary coolant radioactivity for the present month to that for the past month.
| |
| F2 = the factor to be applied to the estimated ratio of final curies released if there are expected differences in treatment of liquid waste for the present month as opposed to the past month (e.g., bypass of filters or demineralizers).
| |
| NUREG-0017 or past experience shall be used to determine the effect of each form of treatment which will vary. F2 = 1 if there are no expected differences.
| |
| The last month should be typical without significant operational differences from the projected month. If there were no releases during last month, do not use that month as the base month if it is estimated that there will be releases for the coming month.
| |
| : b. Whole Body and Maximum Organ when Steam Generator Total Gamma radioactivity Exceeds SE- 7 µCi/ml or Steam Generator Tritium Exceeds 0.02 µCi/ml (Applicable to Units 2 and 3)
| |
| The projected monthly whole body dose (Units 2 or 3) is determined from:
| |
| The monthly projected maximum organ dose (Units 2 or 3) is MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 53 of 137
| |
| | |
| determined from:
| |
| Where:
| |
| DMW=the whole body dose from the last typical previously completed month as calculated per the methods in Section II.C.l.
| |
| DMo=the maximum organ dose from the last typical previously completed month as calculated per the methods in Section II.C.1.
| |
| R1 = the ratio of the total estimated volume of liquid batches to be released in the present month to the volume released in the past month.
| |
| R2 = the ratio of estimated volume of steam generator blowdown to be released in present month to the volume released in the past month.
| |
| F1 = the fraction of curies released last month coming from steam generator blowdown calculated as:
| |
| curies from blowdown curies from blowdown + curies from batch tanks R3 = the ratio of estimated secondary coolant radioactivity for the present month to that for the past month.
| |
| R4 = the ratio of estimated primary coolant radioactivity for the present month to that for the past month.
| |
| F2 = the factor to be applied to the estimated ratio of final curies released if there are expected differences in treatment of liquid waste for the present month as opposed to the past month (e.g., bypass of filters or demineralizers).
| |
| NUREG-0017 or past experience shall be used to determine the effect of each form of treatment which will vary. F2 = 1 if there are no expected differences.

| II.D. Gaseous Dose Calculations
| |
| : 1. Site Release Rate Limits ("Instantaneous")
| |
| Radiological Effluent Controls (Sections III.D.2.a, IVD.2.a, and VD.2.a) for each unit require that the instantaneous off-site dose rates from noble gases released to the atmosphere be limited such that they do not exceed 500 mrem/year at any time to the whole body or 3000 mrem/year to the skin at any time. For iodine-131, 133, tritium, and particulates (half-lives > 8 days), the dose rate from all units shall not exceed 1500 mrem/year at any time to any organ. These limits apply to the combination of releases from all three Units on the site, and are directly related to the radioactivity release rates measured for each Unit.
| |
| : a. Method 1 for Noble Gas Release Rate Limits Instantaneous noble gas release rate for the site:
| |
| G1v /90,000 +Q 2s/560,000 + Gzv/290,000 + Q 3s/560,000 + Q 3v/290,000 .:s_ 1 Where:
| |
| Giv = Noble gas release rate from Spent Fuel Pool Island Vent
| |
| (µCi/sec)
| |
| G2s = Noble gas release rate from MP2 to Millstone Stack (µCi/sec)
| |
| G2v = Noble gas release rate from MP2 Vent (µCi/sec)
| |
| Q3y = Noble gas release rate from MP3 Vent (µCi/sec)
| |
| Q3s = Noble gas release rate from MP3 to Millstone Stack (µCi/sec)
| |
| As long as the above is less than or equal to 1, the doses will be less than or equal to 500 mrem to the total body and less than 3000 mrem to the skin. The limiting factor for the Unit 1 SFPI vent of 90,000 is based on the skin dose limit of 3,000 mrem/year, while all the other factors are based on the whole body dose limit of 500 mrem/year.
| |
| : b. Method 1 Release Rate Limit - I-131, I-133, H-3 and Particulates Half Lives Greater Than 8 Days With releases satisfying the following limit conditions, the dose rate to the maximum organ will be less than 1500 mrem/year from the inhalation pathway:

| ILE. Liquid Discharge Flow Rates And Monitor Setpoints
| |
| : 1. Unit 1 Liquid Waste Effluent Discharge (RE-MG-110)
| |
| The limit on discharge flow rate and setpoint on the Unit 1 liquid waste monitor depend on dilution water flow, radwaste discharge flow, the isotopic composition of the liquid, the background count rate of the monitor and the efficiency of the monitor. Due to the variability of these parameters, the alert and alarm setpoints will be determined prior to the release of each batch. The following method will be used:
| |
| STEP 1:
| |
| From the isotopic analysis and the Effluent Concentration (EC) values for each identified nuclide determine the required reduction factor, i.e.:
| |
| R = R equired Reduction Factor = c l
| |
| '\:""' ~ of nuclide i L...., 10 x EC of nuclide i STEP 2:
| |
| Determine the allowable discharge flow (F)
| |
| F = O.lxRxD Where:
| |
| D = The existing dilution flow which is the any dilution flow from Millstone Unit 2 and/or Unit 3 not being credited for any other radioactivity discharge during discharge of Unit 1 water.
| |
| 0.1 = safety factor to limit discharge concentration to 10% of the Radiological Effluent Control Limit.
| |
| STEP 3:
| |
| Calculate the monitor setpoint as follows:
| |
| Rset = 2 x AC x RCF + Background Where:
| |
| Rset = The setpoint of the monitor.
| |
| AC = The total radwaste effluent concentration (µCi/ml) in the tank.
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 64 of 137
| |
| | |
| RCF = The response correction factor for the effluent line monitor using the current calibration factor or isotopic-specific responses.
| |
| 2 = Tolerance limit which brings the setpoint at twice the expected response of the monitor based on sample analysis. With the safety factor of 0.1 the setpoint would be at 20% of the Radiological Effluent Control Limit.
| |
| Option setpoint:
| |
| A setpoint based upon worst case conditions may be used. Assume the maximum possible discharge flow, a minimum dilution flow not to exceed 100,000 gpm, and a limit of 1 x 10-7 µCi/ml which is lower than any 10CFR20 EC limit except for transuranics. This will assure that low level releases are not terminated due to small fluctuations in radioactivity. When using this option setpoint independent verification of discharge lineup shall be performed. The optional setpoint may be adjusted (increased or decreased) by factors to account for the actual discharge flow and actual dilution flow; however, controls shall be established to ensure that the allowable discharge flow is not exceeded and the dilution flow is maintained.

| |
| : 3. Unit 2 Clean Liquid Radwaste Effluent Line - RM9049 and Aerated Liquid Radwaste Effluent Line - RM9116 The setpoint on the Unit 2 clean and aerated liquid waste effluent lines depend on dilution water flow, radwaste discharge flow, the isotopic composition of the liquid, the background count rate of the monitor and the efficiency of the monitor. Due to the variability of these parameters, an alarm/trip setpoint will be determined prior to the release of each batch.

| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 65 of 137
| |
| | |
| STEP 1:
| |
| From the tank isotopic analysis and the Effluent Concentrations (EC) in 10CFR20, App. B, Table 2, Col. 2 for each identified nuclide determine the required reduction factor, i.e.:
| |
| For Nuclides Other Than Noble Gases:

| |
| "' 'ff of nuclide i L..., 10 x EC of nuclide i For Noble Gases: If the noble gas concentration is less than 1.1 x 10- 2 µCi/ml or the calculated diluted concentration is less than 2 x 10-5 µCi/ml, the reduction factor need not be determined. The concentration of 1.1 x 10- 2 µCi/ml is based on 175 gpm discharge flow, 100,000 gpm dilution flow, and a safety factor of 0.1 (See Note below.) If dilution flow is less than 100,000 gpm, the noble gas concentration limit shall be decreased by the ratio of actual dilution flow to 100,000gpm. For example, if dilution flow is 50,000 gpm, the limit would be reduced by a factor of 0.5 (50,000/100,000).

| F=O.lxRxD Where:
| |
| D = the existing dilution flow (D) from circulating and service water pumps. It may include any Unit 3 flow, or portion of Unit 3 flow, not being credited for dilution of a Unit 3 radioactivity discharge during the time of the Unit 2 discharge.

| |
| | |
| NOTE Note that discharging at this flow rate would yield a discharge concentration corresponding to 10% of the Radiological Effluent Control Limit due to the safety factor of 0.1.
| |
| With this condition on discharge flow rate met, the monitor setpoint can be calculated:
| |
| Rset 2 x AC x RF (See Note 1 below.)
| |
| Where:
| |
| Rset = the setpoint of the monitor (cpm).
| |
| AC = the total radwaste effluent concentration (µCi/ml) in the tank.
| |
| RF = the response factor for the effluent line monitor using the current calibration factor or isotopic-specific responses.
| |
| 2 = the multiple of expected count rate on the monitor based on the radioactivity concentration in the tank.
| |
| This value or that corresponding to 5.6 x 10-5 µCi /ml (Note 2 below),
| |
| whichever is greater, plus background is the trip setpoint. For the latter setpoint, independent valve verification shall be performed and minimum dilution flow in Note 2 shall be verified and if necessary, appropriately adjusted.
| |
| Note 1: If discharging at the allowable discharge rate (F) as determined in above, this setpoint would correspond to 20% of the Radiological Effluent Control limit.
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 67 of 137
| |
| | |
| Note 2: This value is based upon assuming maximum discharge flow (175 gpm) , dilution water flow of 100,000 gpm and a limit of 1 x 10-7 which is lower than any Technical Specification limit (ten times 10CFR20 EC values) except for transuranics. This will assure that low level releases are not terminated due to small fluctuations in radioactivity activity. However, to verify that the correct tank is being discharged when using this value, independent valve verification shall be performed. This value may be adjusted (increased or decreased) by factors to account for the actual discharge flow and actual dilution flow; however, controls shall be established to ensure that the allowable discharge flow is not exceeded and the dilution flow is maintained. Dilution flow may include any Unit 3 flow, or a portion of Unit 3 flow, not being credited for dilution of a Unit 3 radioactive discharge during the time of the Unit 2 discharge.

Unit 2 Reactor Building Closed Cooling Water RM6038 The purpose of the Reactor Building Closed Cooling Water (RBCCW) radiation monitor is to give warning of abnormal radioactivity in the RBCCW system and to prevent releases to the Service Water system which, upon release to the environment, would exceed ten times the concentration values in 10CFR20. According to Calculation RERM-02665-R2, radioactivity in RBCCW water which causes a monitor response of greater than the setpoint prescribed below could exceed ten times thelOCFR20 concentrations upon release to the Service Water system.

| |
| | |
| SETPOINT DURING POWER OPERATIONS:
| |
| To give adequate warning of abnormal radioactivity, the setpoint shall be two times the radiation monitor background reading, provided that the background reading does not exceed 2,000 cpm. The monitor background reading shall be the normal monitor reading. If the monitor background reading exceeds 2,000 cpm, the setpoint shall be set at the background reading plus 2,000 cpm and provisions shall be made to adjust the setpoint if the background decreases.
| |
| SETPOINT DURING SHUTDOWN:
| |
| : 1) During outages not exceeding three months the setpoint shall be two times the radiation monitor background reading, provided that the background reading does not exceed 415 cpm. If the monitor background reading exceeds 415 cpm, the setpoint shall be set at the background reading plus 415 cpm and provisions shall be made to adjust the setpoint if the background decreases.
| |
| : 2) During extended outages exceeding three months, but not exceeding three years, the setpoint shall be two times the radiation monitor background reading, provided that the background reading does not exceed 80 cpm. If the monitor background reading exceeds 80 cpm, the setpoint shall be set at the background reading plus 80 cpm and provisions shall be made to adjust the setpoint if the background decreases.
| |
| PROVISIONS FOR ALTERNATE DILUTION FLOWS:
| |
| These setpoints are based on a dilution flow of 4,000 gpm from one service water train. If additional dilution flow is credited, the setpoint may be adjusted proportionately. For example, the addition of a circulating water pump dilution flow of 100,000 gpm would allow the setpoint to be increased by a factor of 25.

Unit 3 Liquid Waste Monitor - LWS-RE70 The setpoints on the Unit 3 liquid waste monitor depend on dilution water flow, radwaste discharge flow, the isotopic composition of the liquid, the background count rate of the monitor and the efficiency of the monitor. Due to the variability of these parameters, the alert and alarm setpoints will be determined prior to the release of each batch. The following method will be used:

The concentration of 0.013 µCi /ml is based on 100,00 gpm dilution flow and a safety factor of 0.1 (See Note Below.) If dilution flow is less than 100,000 gpm, the noble gas concentration limit shall be decreased by the ratio of actual dilution flow to 100,000gpm.

| NOTE Note that discharging at this flow rate would yield a discharge concentration corresponding to 10% of the Radiological Effluent Control Limit due to the safety factor of 0.1.
| |
| With this condition on discharge flow rate met, the monitor setpoint can be calculated:

| | |
| NOTE
| |
| : 1. If discharging at the allowable discharge rate (F) as determined above, this Alarm setpoint would yield a discharge concentration corresponding to 20% of the Radiological Effluent Control limit.

| : 2. This value is based upon assuming maximum discharge flow (150 gpm), dilution water flow of 100,000 gpm, and a limit of 1 x 10-7 µCi/ml which is lower than any Technical Specification limit (ten times 10CFR20 EC values) except for transuranics. This will assure that low level releases are not terminated due to small fluctuations in radioactivity. However, to verify that the correct tank is being discharged when using this value, independent valve verification shall be performed. This value may be adjusted (increased or decreased) by factors to account for the actual discharge flow and actual dilution flow; however, controls shall be established to ensure that the allowable discharge flow is not exceeded and the dilution flow is maintained.

If effluent conditions from Unit 2 vent releases reach 95,000 µCi/sec, releases from Units 1 and 3 vents and from Units 2 and 3 releases to the Millstone Stack shall be determined to ensure that the sum of the individual noble gas release rates do not cause the site limit to be exceeded. Use Section II.D.l.a. and Section 4.2 of MP-22-REC-REF03, "REMODCM Technical Information Document,"

| in making this determination.
| |
| The alarm setpoint shall be set at or below the monitor reading in cpm corresponding to the Unit 2 vent portion of the limit. The setpoint shall be set at or below 42,000 CPM.

| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 77 of 137
| |
| | |
| Batch releases of waste gas shall be limited to less than 10% of the Unit 2 releases to the Millstone Stack release rate limits. Therefore, the waste gas decay tank monitor setpoint should be set not to exceed 7,200 µCi /sec. If the setpoint exceeds 7,200 µCi/sec, the release shall be automatically terminated.
| |
| The MP2 waste gas decay tank monitor (given µCi/cc per cpm) calibration curve and the tank discharge rate is used to assure that the concentration of gaseous radioactivity being released from a waste gas decay tank does not cause the setpoint of 7,200 µCi /sec to be exceeded.
| |
| : 7. Unit 3 Vent Noble Gas Monitor - HVR-RElOB The instantaneous release rate limit from the site shall be set in accordance with the conditions given in Section II.D.l.a. in order to satisfy Unit 3 Radiological Effluent Controls in Sections V.C.2. and V.D.2.a.
| |
| For releases from Unit 3 vent, the allocated portion of the site instantaneous release rate limit is 95,000 µCi /sec. This assumes that 33% of the site limit is assigned to Unit 3 vent releases. If effluent conditions from Unit 3 vent releases reach 95,000 µCi/sec, releases from Units 1 and 2 vents, Unit 3 ESF vent and from Units 2 and 3 releases to the Millstone Stack shall be determined to ensure that the sum of the individual noble gas release rates do not cause the site limit to be exceeded. Use Section II.D.l.a. and Section 4.2 of MP-22-REC-REF03, "REMO DCM Technical Information Document," in making this determination.
| |
| The alarm setpoint shall be set at or below the monitor reading corresponding to the Unit 3 vent portion of the limit. The setpoint shall be set at or below 8.4 x 10- 4 µCi/cc.
| |
| : 8. Unit 3 Engineering Safeguards Building Monitor - HVQ-RE49 For releases from Unit 3 ESF vent, the allocated portion of the site instantaneous release rate limit is 2,900 µCi/sec. This applies 1% of the Unit 3 Vent release rate limit (see Section II.D.l.a.) to Unit 3 ESF vent releases.
| |
| If effluent conditions from Unit 3 ESF vent releases reach 2,900 µCi /sec, releases from Units 1 and 2 vents, Unit 3 vent and from Units 2 and 3 releases to the Millstone Stack shall be determined to ensure that the sum of the individual noble gas release rates do not cause the site limit to be exceeded. Use Section II.D.l.a. and Section 4.2 of MP-22-REC-REF03, "REMODCM Technical Information Document,"
| |
| in making this determination.
| |
| The Alarm setpoint shall be set at or below the value of 5.9E-4 µCi/cc. This setpoint assumes a monitor flow rate of 10,500 cfm. However, only 6,000 cfm is monitored. By assuming 10,500 cfm the setpoint is conservatively low.

| APPENDIX II.A REMODCM METHODOLOGY CROSS-REFERENCES Radiological effluent controls (Sections III, IV, and V) identify the requirements for monitoring and limiting liquid and gaseous effluents releases from the site such the resulting dose impacts to members of the public are kept to '~ Low As Reasonably Achievable" (ALARA). The demonstration of compliance with the dose limits is by calculational models that are implemented by Section II of the REMODCM.
| |
| Table App. II.A-1 provides a cross- reference guide between liquid and gaseous effluent release limits and those sections of the REMODCM, which are used to determine compliance. It also shows the administrative Technical Specifications which reference the REMO DCM for operation of radioactive waste processing equipment. This table also provides a quick outline of the applicable limits or dose objectives and the required actions if those limits are exceeded. Details of the effluent control requirements and the implementing sections of the REMO DCM should be reviewed directly for a full explanation of the requirements.

| |
| | |
| SECTION III. REMODCM UNIT ONE CONTROLS III.A. Introduction The purpose of this section is to provide the following for Millstone Unit One:
| |
| : a. the effluent radiation monitor controls and surveillance requirements,
| |
| : b. the effluent radioactivity concentration and dose controls and surveillance requirements, and
| |
| : c. the bases for the controls and surveillance requirements.
| |
| Definitions of certain terms are provided as an aid for implementation of the controls and requirements.
| |
| Some surveillance requirements refer to specific sub-sections in Sections I and II as part of their required actions III.B. Definitions and Surveillance Requirement (SR) Applicability III.B.1 - Definitions The defined terms of this sub-section appear in capitalized type and are applicable throughout Section III.
| |
| : 1. ACTION - that part of a Control that prescribes remedial measures required under designated conditions.
| |
| : 2. INSTRUMENT CALIBRATION - the adjustment, as necessary, of the instrument output such that it responds within the necessary range and accuracy to know values of the parameter that the instrument monitors. The INSTRUMENT CALIBRATION shall encompass those components, such as sensors, displays, and trip functions, required to perform the specified safety function(s). The INSTRUMENT CALIBRATION shall include the INSTRUMENT FUNCTIONAL TEST and may be performed by means of any series of sequential, overlapping, or total channel steps so that the entire channel is calibrated.
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 82 of 137
| |
| : 3. INSTRUMENT FUNCTIONAL TEST - the injection of a simulated or actual signal into the channel as close to the sensor as practicable to verify that the instrument is FUNCTIONAL, including all components in the channel, such as alarms, interlocks, displays, and trip functions, required to perform the specified safety function(s). For digital instruments, the computer database may be manipulated, in lieu of a signal injection, to verify operability of alarm and/or trip functions. The INSTRUMENT FUNCTIONAL TEST may be performed by means of any series of sequential, overlapping, or total channel steps so that the entire channel is tested.
| |
| : 4. CHANNEL CHECK - the qualitative determination of functionality by observation of behavior during operation. This determination shall include, where possible, comparison of the instrument with other independent instruments measuring the same variable.
| |
| : 5. FUNCTIONAL - An instrument shall be FUNCTIONAL when it is capable of performing its specified functions(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 instrument to perform its functions(s) are also capable of performing their related support function(s).
| |
| : 6. REAL MEMBER OF THE PUBLIC - an individual, not occupationally associated with the Millstone site, who is exposed to existing dose pathways at one particular location. This does not include employees of the utility or utilities which own a Millstone plant and utility contractors and vendors.
| |
| Also excluded are persons who enter the Millstone site to service equipment or to make deliveries. This does include persons who use portions of the Millstone site for recreational, occupational, or other purposes not associated with any of the Millstone plants.
| |
| : 7. SITE BOUNDARY - that line beyond which the land is not owned, leased, or otherwise controlled by the licensee.
| |
| : 8. SOURCE CHECK - the qualitative assessment of channel response when the channel is exposed to radiation.
| |
| : 9. RADIOACTIVE WASTE TREATMENT SYSTEMS - Radioactive Waste Treatment Systems are those liquid, gaseous, and solid waste systems which are required to maintain control over radioactive materials in order to meet the controls set forth in this section.
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 83 of 137
| |
| | |
| 111.B.2 - Surveillance Requirement (SR) Applicability
| |
| : 1. SRs shall be met during specific conditions in the Applicability for individual LCOs unless otherwise stated in the SR. Failure to meet a Surveillance, whether such failure is experienced during the performance of the Surveillance or between performances of the Surveillance, shall be failure to meet the LCO. Failure to perform a Surveillance within the specified Frequency shall be failure to meet the LCO except as provided in III.B.2 3.
| |
| Surveillances do not have to be performed on nonfunctional equipment or variables outside specified limits.
| |
| : 2. The specified Frequency for each SR is met if the Surveillance is performed within 1.25 times the interval specified in the Frequency, as measured from the previous performance or as measured from the time a specified condition of the frequency is met.
| |
| : 3. If it is discovered that a Surveillance was not performed within its specified frequency, then compliance with the requirement to declare the LCO not met may be delayed from the time of discovery up to 24 hours or up to the limit of the specified frequency, whichever is less. This delay period is permitted to allow performance of the surveillance. If the Surveillance is not performed within the delay period, the LCO must immediately be declared not met and the applicable Condition(s) must be entered. The Completion Times of the Required Actions begin immediately upon expiration of the delay period. When the Surveillance is performed within the delay period and the Surveillance is not met, the LCO must immediately be declared not met and the applicable Condition(s) must be entered. The Completion Times of the Required Actions begin immediately upon failure to meet the Surveillance.

| | |
| SECTION I. RADIOLOGICAL EFFLUENT MONITORING MANUAL (REMM)
| |
| I.A Introduction The purpose of Section I of this manual is to provide the sampling and analysis programs which provide input to Section II for calculating liquid and gaseous effluent concentrations and offsite doses. Guidelines are provided for operating radioactive waste treatment systems in order that offsite doses are kept As-Low-As-Reasonably-Achievable (ALARA).
| |
| The Radiological Environmental Monitoring Program outlined within this manual provides confirmation that the measurable concentrations of radioactive material in the environment as a result of operations at the Millstone Site are not higher than expected.
| |
| In addition, this manual outlines the information required to be submitted to the NRC in both the Annual Radiological Environmental Operating Report and the Radioactive Effluent Release Report.
| |
| MP-22-REC-REF03, "REMODCM Technical Information Document (TID)," has additional bases and technical information. It also contains a list of exceptions to Regulatory Guide 1.21 (see Section 2 of the TID).
| |
| I.B. Responsibilities All changes to the Radiological Effluent Monitoring Manual (REMM) shall be reviewed and approved by the Facility Safety Review Committee prior to implementation.
| |
| All changes and their rationale shall be documented in the Radioactive Effluent Release Report.
| |
| It shall be the responsibility of the Site Vice President Millstone to ensure that this manual is used as required by the administrative controls of the Technical Specifications. The delegation of implementation responsibilities is delineated in MP-22-REC-PRG, "Radiological Effluent Program."
| |
| I.C. Liquid Effluents
| |
| : 1. Liquid Effluent Sampling and Analysis Program Radioactive liquid wastes shall be sampled and analyzed in accordance with the program specified in Table I.C.-1 for Millstone Unit No. 1, Table I.C.-2 for Millstone Unit No. 2, and Table I.C.-3 for Millstone Unit No. 3. The results of the radioactive analyses shall be input to the methodology of Section II to assure that the concentrations at the point of release are maintained within the limits of Radiological Effluent Controls (Section III.D.l.a. for Millstone Unit No. 1, Section IVD.l.a. for Millstone Unit No.
| |
| 2, and Section VD.La. for Millstone Unit No. 3).

| TABLE NOTATIONS A. The 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 radiochemical separation):
| |
| LLD= 4.66 Sb (E )(V)(2.22xl0 6)(Ye-AL1~
| |
| Where :
| |
| * LLD is the lower limit of detection as defined above (as µCi per unit mass or volume)
| |
| * Sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)
| |
| * E is the counting efficiency (as counts per transformation)
| |
| * V is the sample size (in units of mass or volume)
| |
| * 2.22 x 10 6 is the number of transformations per minute per µCi
| |
| * Y is the fractional radiochemical yield (when applicable)
| |
| * "' is the radioactive decay constant for the particular radionuclide
| |
| * Lit is the elapsed time between midpoint of sample collection and midpoint of counting time It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement.

| |
| | |
| Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions . Occasionally background fluctuations, unavoidably small sample sizes , the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable.

| H. Waste Gas Storage Tanks are normally released on a batch basis via the Millstone Stack.
| |
| However, for the purpose of tank maintenance, inspection, or reduction of oxygen concentration , a waste gas tank may be vented or purged with nitrogen and released to the environment via the normal or alternate pathway using one of the following methods:
| |
| Method A: Without a permit provided the following conditions are met:
| |
| (1) The tank has been previously discharged with a permit.
| |
| (2) The current tank pressure is less than 5 PSIG .
| |
| (3) No radioactive gases have been added to the tank since the previous discharge from the tank.
| |
| (4) Valve lineups are verified to ensure that no radioactive waste gases will be added to the tank.
| |
| (5) Prior to initiation of the vent or purge, a sample of the gas in the tank will be taken and analyzed for any residual gamma emitters and tritium. The tank may be released if:
| |
| a) Tank radioactivity is less than 1% of the radioactivity released in the previous batch release from the tank, or less than 1% of the radioactivity released to date for the calendar year, and b) the radioactivity of Kr-85 and Xe-133 is less than 0.01 Ci and the radioactivity of all other gases is less than 0.001 Ci.
| |
| Method B: With a permit provided valve lineups are verified to ensure that no radioactive waste gases will be added to the tank.
| |
| I. IE compared to the radioactivity at the time of the air sample, a Radiation Monitor RM8123 or RM8262 gas channel increases by a factor of two, THEN a new containment air sample shall be taken.
| |
| IE containment noble gas radioactivity exceeds 1E-6 µCi/cc as indicated by the last grab sample, THEN sampling frequency shall be increased to weekly until such time that the radioactivity is less than 1E-6 µCi/cc.

| I.E. Radiological Environmental Monitoring
| |
| : 1. Sampling and Analysis The radiological sampling and analyses provide 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 plant operation. This monitoring program thereby supplements the radiological effluent 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.
| |
| Program changes may be made based on operational experience.
| |
| The sampling and analyses shall be conducted as specified in Table I.E. -1 for the locations shown Table I.E.-2. Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment or other legitimate reasons. If specimens are unobtainable due to sampling equipment malfunction, every effort shall be made to complete corrective action prior to the end of the next sampling period.
| |
| All deviations from the sampling schedule shall be documented in the Annual Radiological Environmental Operating Report pursuant to Section I.F.l. It is recognized that, at times, it may not be possible or practicable to obtain samples of the media of choice at the most desired 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. Any of the above occurrences shall be documented in the Annual Radiological Environmental Operating Report, which is submitted to the U . S. Nuclear Regulatory Commission prior to May 1 of each year.
| |
| If the level of radioactivity in an environmental sampling medium at one or more of the locations specified in Table I.E. -2 exceeds the report levels of Table I.E. -3 when averaged over any calendar quarter, prepare and submit to the Commission within 30 days from receipt of sample results, a Special Report which includes an evaluation of any release conditions, environmental factors or other aspects which caused the limits of Table I.E.-3 to be exceeded. When more than one of the radionuclides in Table I.E.-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)
| |
| MP-22-REC-BAPOl STOP TH INK ACT REVIEW Rev. 029 36 of 137
| |
| | |
| When radionuclides other than those in Table I.E.-3 are detected and are the result of plant effluents, this report shall be submitted if the potential annual dose to an individual is equal to or greater than the appropriate calendar year limit of the Radiological Effluent Controls (Sections III.D.l.b.,
| |
| III.D.2.b., or III.D.2.c. for Unit 1; Sections IV.D.l.b., IV.D.2.b. , or IV.D.2.c.
| |
| for Unit 2; and Sections V.D.l.b. , V.D.2.b., or V.D.2.c. for Unit 3). This report is not required if the measured level of radioactivity was not the result of plant effluents, however, in such an event, the condition shall be reported and described in the Annual Radiological Environmental Operating Report.
| |
| The detection capabilities required by Table I.E.-4 are state-of-the-art for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement. All analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors will be identified and described in the Annual Radiological Environmental Operating Report.

| SECTION IL OFFSITE DOSE CALCULATION MANUAL (ODCM)
| |
| II.A. Introduction The purpose of the Offsite Dose Calculation Manual (Section II of the REMODCM) is to provide the parameters and methods to be used in calculating offsite doses and effluent monitor setpoints at the Millstone Nuclear Power Station. Included are methods for determining maximum individual whole body and organ doses due to liquid and gaseous effluents to assure compliance with the regulatory dose limitations in 10 CFR 50, Appendix I. Also included are methods for performing dose projections to assure compliance with the liquid and gaseous treatment system functionality sections of the Radiological Effluent Monitoring Manual (REMM - Section I of the REMODCM). The manual also includes the methods used for determining quarterly and annual doses for inclusion in the Radioactive Effluent Release Report.
| |
| The bases for selected site-specific factors used in the dose calculation methodology are provided in MP-22-REC-REF03, "REMODCM Technical Information."
| |
| Another section of this manual discusses the methods to be used in determining effluent monitor alarm/trip setpoints to be used to ensure compliance with the instantaneous release rate limits in Sections III.D.2.a., IV.D.2.a., and V.D.2.a.
| |
| This manual includes the methods to be used in performance of the surveillance requirements in the Radiological Effluent Controls of Sections III, IV, and V.
| |
| Appendix A, Tables App.A-1 provide a cross-reference of effluent requirements and applicable methodologies contained in the REMODCM.
| |
| II.B. Responsibilities All changes to the Offsite Dose Calculation Manual (ODCM) shall be reviewed and approved by the Facilities Safety Review Committee prior to implementation.
| |
| All changes and their rationale shall be documented in the Radioactive Effluent Release Report.
| |
| It shall be the responsibility of the Site Vice President Millstone to ensure that this manual is used as required by the administrative controls of the Technical Specifications. The delegation of implementation responsibilities is delineated in the MP-22-REC-PRG, "Radiological Effluent Control."

| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 51 of 137
| |
| | |
| II.C. Liquid Dose Calculations Radiological Effluent Controls (Sections III, IV, and V) limit whole body and maximum organ doses to an individual member of the public to 1.5 mrem whole body and 5 mrem maximum organ per calendar quarter and 3 mrem whole body and 10 mrem maximum organ per year from liquid effluents released from each unit. (See Appendix A, Table App.A-1 for cross-reference effluent control requirements and applicable sections in the REMO DCM which are used to determine compliance). In addition, installed portions of liquid radwaste treatment system are required to be operated to reduce radioactive materials in liquid effluents when the projected dose over 31 days from applicable waste streams exceeds 0.006 mrem whole body or 0.02 mrem maximum organ. This part of the REMODCM provides the calculation methodology for determining the doses from radioactive materials released into liquid pathways of exposure associated with routine discharges.
| |
| : 1. Monthly, Quarterly, and Annual Dose Calculation (Applicable to All Units)
| |
| For each Unit, whole body and maximum organ doses from liquid effluents shall be calculated at least once per 31 days (or monthly) using the methodology of Regulatory Guide 1.109, Rev. 1. The calculation shall include contributions from all analyses required by Table I.C-1 for Unit 1, Table I.C-2 for Unit 2, and Table I.C-3 for Unit 3 recorded to date. If any required analyses have not yet been completed for the dose period, an estimate of dose from unanalyzed isotopes shall be included in the dose total.
| |
| Results of these dose calculations shall be summed to determine compliance with quarterly and annual dose limits for each Unit.
| |
| : 2. Monthly Dose Projections Section I.C.2.a. of the REMM requires that certain portions of the liquid radwaste treatment equipment be used to reduce radioactive liquid effluents when the projected doses for each Unit (made at least once per 31 days) exceeds 0.006 mrem whole body or 0.02 mrem to any organ. The following methods are applied in the estimation of monthly dose projections:
| |
| : a. Whole Body and Maximum Organ when Steam Generator Total Gamma Radioactivity is less than SE- 7 µCi /ml and Steam Generator Tritium is less than 0.02 µCi/ml (Applicable to Units 2 and 3)
| |
| The projected monthly whole body dose (Units 2 or 3) is determined from:
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 52 of 137
| |
| | |
| The monthly projected maximum organ dose (Units 2 or 3) is determined from:
| |
| Where:
| |
| DMW = the whole body dose from the last typical previously completed month as calculated per the methods in Section II.C.l.
| |
| DMo = the maximum organ dose from the last typical previously completed month as calculated per the methods in Section IL C. l.
| |
| R1 = the ratio of the total estimated volume of liquid batches to be released in the present month to the volume released in the past month.
| |
| Ri = the ratio of estimated primary coolant radioactivity for the present month to that for the past month.
| |
| F2 = the factor to be applied to the estimated ratio of final curies released if there are expected differences in treatment of liquid waste for the present month as opposed to the past month (e.g., bypass of filters or demineralizers).
| |
| NUREG-0017 or past experience shall be used to determine the effect of each form of treatment which will vary. F2 = 1 if there are no expected differences.
| |
| The last month should be typical without significant operational differences from the projected month. If there were no releases during last month, do not use that month as the base month if it is estimated that there will be releases for the coming month.
| |
| : b. Whole Body and Maximum Organ when Steam Generator Total Gamma radioactivity Exceeds SE- 7 µCi/ml or Steam Generator Tritium Exceeds 0.02 µCi/ml (Applicable to Units 2 and 3)
| |
| The projected monthly whole body dose (Units 2 or 3) is determined from:
| |
| The monthly projected maximum organ dose (Units 2 or 3) is MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 53 of 137
| |
| | |
| determined from:
| |
| Where:
| |
| DMW=the whole body dose from the last typical previously completed month as calculated per the methods in Section II.C.l.
| |
| DMo=the maximum organ dose from the last typical previously completed month as calculated per the methods in Section II.C.1.
| |
| R1 = the ratio of the total estimated volume of liquid batches to be released in the present month to the volume released in the past month.
| |
| R2 = the ratio of estimated volume of steam generator blowdown to be released in present month to the volume released in the past month.
| |
| F1 = the fraction of curies released last month coming from steam generator blowdown calculated as:
| |
| curies from blowdown curies from blowdown + curies from batch tanks R3 = the ratio of estimated secondary coolant radioactivity for the present month to that for the past month.
| |
| R4 = the ratio of estimated primary coolant radioactivity for the present month to that for the past month.
| |
| F2 = the factor to be applied to the estimated ratio of final curies released if there are expected differences in treatment of liquid waste for the present month as opposed to the past month (e.g., bypass of filters or demineralizers).
| |
| NUREG-0017 or past experience shall be used to determine the effect of each form of treatment which will vary. F2 = 1 if there are no expected differences.

| II.D. Gaseous Dose Calculations
| |
| : 1. Site Release Rate Limits ("Instantaneous")
| |
| Radiological Effluent Controls (Sections III.D.2.a, IVD.2.a, and VD.2.a) for each unit require that the instantaneous off-site dose rates from noble gases released to the atmosphere be limited such that they do not exceed 500 mrem/year at any time to the whole body or 3000 mrem/year to the skin at any time. For iodine-131, 133, tritium, and particulates (half-lives > 8 days), the dose rate from all units shall not exceed 1500 mrem/year at any time to any organ. These limits apply to the combination of releases from all three Units on the site, and are directly related to the radioactivity release rates measured for each Unit.
| |
| : a. Method 1 for Noble Gas Release Rate Limits Instantaneous noble gas release rate for the site:
| |
| G1v /90,000 +Q 2s/560,000 + Gzv/290,000 + Q 3s/560,000 + Q 3v/290,000 .:s_ 1 Where:
| |
| Giv = Noble gas release rate from Spent Fuel Pool Island Vent
| |
| (µCi/sec)
| |
| G2s = Noble gas release rate from MP2 to Millstone Stack (µCi/sec)
| |
| G2v = Noble gas release rate from MP2 Vent (µCi/sec)
| |
| Q3y = Noble gas release rate from MP3 Vent (µCi/sec)
| |
| Q3s = Noble gas release rate from MP3 to Millstone Stack (µCi/sec)
| |
| As long as the above is less than or equal to 1, the doses will be less than or equal to 500 mrem to the total body and less than 3000 mrem to the skin. The limiting factor for the Unit 1 SFPI vent of 90,000 is based on the skin dose limit of 3,000 mrem/year, while all the other factors are based on the whole body dose limit of 500 mrem/year.
| |
| : b. Method 1 Release Rate Limit - I-131, I-133, H-3 and Particulates Half Lives Greater Than 8 Days With releases satisfying the following limit conditions, the dose rate to the maximum organ will be less than 1500 mrem/year from the inhalation pathway:

| |
| : 2) Site release rate of particulates with half-lives greater than 8 days and tritium (where the critical organ is a composite of target organs for a mix of radionuclides):
| |
| DRorgl + DRorg2 + DRorg3 ~ 1 Where the contribution from each Unit is calculated from:
| |

| ILE. Liquid Discharge Flow Rates And Monitor Setpoints
| |
| : 1. Unit 1 Liquid Waste Effluent Discharge (RE-MG-110)
| |
| The limit on discharge flow rate and setpoint on the Unit 1 liquid waste monitor depend on dilution water flow, radwaste discharge flow, the isotopic composition of the liquid, the background count rate of the monitor and the efficiency of the monitor. Due to the variability of these parameters, the alert and alarm setpoints will be determined prior to the release of each batch. The following method will be used:
| |
| STEP 1:
| |
| From the isotopic analysis and the Effluent Concentration (EC) values for each identified nuclide determine the required reduction factor, i.e.:
| |
| R = R equired Reduction Factor = c l
| |
| '\:""' ~ of nuclide i L...., 10 x EC of nuclide i STEP 2:
| |
| Determine the allowable discharge flow (F)
| |
| F = O.lxRxD Where:
| |
| D = The existing dilution flow which is the any dilution flow from Millstone Unit 2 and/or Unit 3 not being credited for any other radioactivity discharge during discharge of Unit 1 water.
| |
| 0.1 = safety factor to limit discharge concentration to 10% of the Radiological Effluent Control Limit.
| |
| STEP 3:
| |
| Calculate the monitor setpoint as follows:
| |
| Rset = 2 x AC x RCF + Background Where:
| |
| Rset = The setpoint of the monitor.
| |
| AC = The total radwaste effluent concentration (µCi/ml) in the tank.
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 64 of 137
| |
| | |
| RCF = The response correction factor for the effluent line monitor using the current calibration factor or isotopic-specific responses.
| |
| 2 = Tolerance limit which brings the setpoint at twice the expected response of the monitor based on sample analysis. With the safety factor of 0.1 the setpoint would be at 20% of the Radiological Effluent Control Limit.
| |
| Option setpoint:
| |
| A setpoint based upon worst case conditions may be used. Assume the maximum possible discharge flow, a minimum dilution flow not to exceed 100,000 gpm, and a limit of 1 x 10-7 µCi/ml which is lower than any 10CFR20 EC limit except for transuranics. This will assure that low level releases are not terminated due to small fluctuations in radioactivity. When using this option setpoint independent verification of discharge lineup shall be performed. The optional setpoint may be adjusted (increased or decreased) by factors to account for the actual discharge flow and actual dilution flow; however, controls shall be established to ensure that the allowable discharge flow is not exceeded and the dilution flow is maintained.

| : 2. Reserved
| |
| : 3. Unit 2 Clean Liquid Radwaste Effluent Line - RM9049 and Aerated Liquid Radwaste Effluent Line - RM9116 The setpoint on the Unit 2 clean and aerated liquid waste effluent lines depend on dilution water flow, radwaste discharge flow, the isotopic composition of the liquid, the background count rate of the monitor and the efficiency of the monitor. Due to the variability of these parameters, an alarm/trip setpoint will be determined prior to the release of each batch.

| The following method will be used:
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 65 of 137
| |
| | |
| STEP 1:
| |
| From the tank isotopic analysis and the Effluent Concentrations (EC) in 10CFR20, App. B, Table 2, Col. 2 for each identified nuclide determine the required reduction factor, i.e.:
| |
| For Nuclides Other Than Noble Gases:
| |
| R1 = Required Reduction Factor=-------- 1
| |
| "' 'ff of nuclide i L..., 10 x EC of nuclide i For Noble Gases: If the noble gas concentration is less than 1.1 x 10- 2 µCi/ml or the calculated diluted concentration is less than 2 x 10-5 µCi/ml, the reduction factor need not be determined. The concentration of 1.1 x 10- 2 µCi/ml is based on 175 gpm discharge flow, 100,000 gpm dilution flow, and a safety factor of 0.1 (See Note below.) If dilution flow is less than 100,000 gpm, the noble gas concentration limit shall be decreased by the ratio of actual dilution flow to 100,000gpm. For example, if dilution flow is 50,000 gpm, the limit would be reduced by a factor of 0.5 (50,000/100,000).

| |
| Determine the allowable discharge flow (F) in gpm:
| |
| F=O.lxRxD Where:
| |
| D = the existing dilution flow (D) from circulating and service water pumps. It may include any Unit 3 flow, or portion of Unit 3 flow, not being credited for dilution of a Unit 3 radioactivity discharge during the time of the Unit 2 discharge.
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEWRev. 029 66 of 137
| |
| | |
| NOTE Note that discharging at this flow rate would yield a discharge concentration corresponding to 10% of the Radiological Effluent Control Limit due to the safety factor of 0.1.
| |
| With this condition on discharge flow rate met, the monitor setpoint can be calculated:
| |
| Rset 2 x AC x RF (See Note 1 below.)
| |
| Where:
| |
| Rset = the setpoint of the monitor (cpm).
| |
| AC = the total radwaste effluent concentration (µCi/ml) in the tank.
| |
| RF = the response factor for the effluent line monitor using the current calibration factor or isotopic-specific responses.
| |
| 2 = the multiple of expected count rate on the monitor based on the radioactivity concentration in the tank.
| |
| This value or that corresponding to 5.6 x 10-5 µCi /ml (Note 2 below),
| |
| whichever is greater, plus background is the trip setpoint. For the latter setpoint, independent valve verification shall be performed and minimum dilution flow in Note 2 shall be verified and if necessary, appropriately adjusted.
| |
| Note 1: If discharging at the allowable discharge rate (F) as determined in above, this setpoint would correspond to 20% of the Radiological Effluent Control limit.
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 67 of 137
| |
| | |
| Note 2: This value is based upon assuming maximum discharge flow (175 gpm) , dilution water flow of 100,000 gpm and a limit of 1 x 10-7 which is lower than any Technical Specification limit (ten times 10CFR20 EC values) except for transuranics. This will assure that low level releases are not terminated due to small fluctuations in radioactivity activity. However, to verify that the correct tank is being discharged when using this value, independent valve verification shall be performed. This value may be adjusted (increased or decreased) by factors to account for the actual discharge flow and actual dilution flow; however, controls shall be established to ensure that the allowable discharge flow is not exceeded and the dilution flow is maintained. Dilution flow may include any Unit 3 flow, or a portion of Unit 3 flow, not being credited for dilution of a Unit 3 radioactive discharge during the time of the Unit 2 discharge.

Unit 2 Reactor Building Closed Cooling Water RM6038 The purpose of the Reactor Building Closed Cooling Water (RBCCW) radiation monitor is to give warning of abnormal radioactivity in the RBCCW system and to prevent releases to the Service Water system which, upon release to the environment, would exceed ten times the concentration values in 10CFR20. According to Calculation RERM-02665-R2, radioactivity in RBCCW water which causes a monitor response of greater than the setpoint prescribed below could exceed ten times thelOCFR20 concentrations upon release to the Service Water system.

| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 69 of 137
| |
| | |
| SETPOINT DURING POWER OPERATIONS:
| |
| To give adequate warning of abnormal radioactivity, the setpoint shall be two times the radiation monitor background reading, provided that the background reading does not exceed 2,000 cpm. The monitor background reading shall be the normal monitor reading. If the monitor background reading exceeds 2,000 cpm, the setpoint shall be set at the background reading plus 2,000 cpm and provisions shall be made to adjust the setpoint if the background decreases.
| |
| SETPOINT DURING SHUTDOWN:
| |
| : 1) During outages not exceeding three months the setpoint shall be two times the radiation monitor background reading, provided that the background reading does not exceed 415 cpm. If the monitor background reading exceeds 415 cpm, the setpoint shall be set at the background reading plus 415 cpm and provisions shall be made to adjust the setpoint if the background decreases.
| |
| : 2) During extended outages exceeding three months, but not exceeding three years, the setpoint shall be two times the radiation monitor background reading, provided that the background reading does not exceed 80 cpm. If the monitor background reading exceeds 80 cpm, the setpoint shall be set at the background reading plus 80 cpm and provisions shall be made to adjust the setpoint if the background decreases.
| |
| PROVISIONS FOR ALTERNATE DILUTION FLOWS:
| |
| These setpoints are based on a dilution flow of 4,000 gpm from one service water train. If additional dilution flow is credited, the setpoint may be adjusted proportionately. For example, the addition of a circulating water pump dilution flow of 100,000 gpm would allow the setpoint to be increased by a factor of 25.

| 7b. Unit 2 Service Water, and RBCCW Sump and Turbine Building Sump Effluent Concentration Limitation Results of analyses of service water, RBCCW sump and turbine building sump samples taken in accordance with Table I.C.-2 of Section I of the REMODCM shall be used to limit radioactivity concentrations in the service water, RBCCW sump and turbine building sump effluents to less than ten times the limits in 10CFR20, Appendix B.

| : 8. Unit 3 Liquid Waste Monitor - LWS-RE70 The setpoints on the Unit 3 liquid waste monitor depend on dilution water flow, radwaste discharge flow, the isotopic composition of the liquid, the background count rate of the monitor and the efficiency of the monitor. Due to the variability of these parameters, the alert and alarm setpoints will be determined prior to the release of each batch. The following method will be used:
| |
| Step 1:
| |
| From the tank isotopic analysis and the Effluent Concentration (EC) values for each identified nuclide determine the required reduction factor, i.e.:

The concentration of 0.013 µCi /ml is based on 100,00 gpm dilution flow and a safety factor of 0.1 (See Note Below.) If dilution flow is less than 100,000 gpm, the noble gas concentration limit shall be decreased by the ratio of actual dilution flow to 100,000gpm.

| |
| | |
| NOTE Note that discharging at this flow rate would yield a discharge concentration corresponding to 10% of the Radiological Effluent Control Limit due to the safety factor of 0.1.
| |
| With this condition on discharge flow rate met, the monitor setpoint can be calculated:
| |
| Rset = 2 x AC x RCF (see Note 1)
| |
| Where:
| |
| Rset= The setpoint of the monitor.

| |
| | |
| NOTE
| |
| : 1. If discharging at the allowable discharge rate (F) as determined above, this Alarm setpoint would yield a discharge concentration corresponding to 20% of the Radiological Effluent Control limit.
| |
| : 2. This value is based upon assuming maximum discharge flow (150 gpm), dilution water flow of 100,000 gpm, and a limit of 1 x 10-7 µCi/ml which is lower than any Technical Specification limit (ten times 10CFR20 EC values) except for transuranics. This will assure that low level releases are not terminated due to small fluctuations in radioactivity. However, to verify that the correct tank is being discharged when using this value, independent valve verification shall be performed. This value may be adjusted (increased or decreased) by factors to account for the actual discharge flow and actual dilution flow; however, controls shall be established to ensure that the allowable discharge flow is not exceeded and the dilution flow is maintained. Dilution flow may include Unit 2 flow, or portion of Unit 2 flow, not being credited for dilution of a Unit 2 discharge during the time of the Unit 3 discharge.

| : 11. Unit 3 Steam Generator Blowdown - SSR-RE08 and Unit 3 Steam Generator Blowdown Effluent Concentration Limitation lla. Unit 3 Steam Generator Blowdown - SSR-RE08 The alarm setpoint for this monitor assumes:
| |
| : a. Steam generator blowdown rate of 400 gpm (maximum blowdown total including weekly cleaning of generators - per ERC 25212-ER-99-0133).
| |
| : b. The release rate limit is conservatively set at 3 x 10- 8 µCi/ml which is well below any 10CFR20 Effluent Concentration except for transuranics*.
| |
| : c. Circulating and service water dilution flow during periods of blowdown = 100,000 gpm.

| |
| Alarm (µCi/m[) = lO~O~OO x 3xl0- 8 + background = 7.5xl0-{i µCi/ml + background This setpoint may be increased through proper administrative controls if the steam generator blowdown rate is maintained less than 400 gpm and/or more than 100,000 gpm dilution flow are available. The amount of the increase would correspond to the ratio of flows to those assumed above or:

| Background = 3xl0 - 8µCi/ ml x + Background total S/ G blowdown (gpm)
| |
| When using the adjusted alarm, ensure that any other simultaneous discharge does not cause an exceedance of regulatory limits.
| |
| NOTE The Steam Generator Blowdown alarm criteria is in practice based on setpoints required to detect allowable levels of primary to secondary leakage. This alarm criteria is typically more restrictive than that required to meet discharge limits. This fact shall be verified, however, whenever the alarm setpoint is recalculated.

| |
| : 8. Unit 3 Engineering Safeguards Building Monitor - HVQ-RE49 For releases from Unit 3 ESF vent, the allocated portion of the site instantaneous release rate limit is 2,900 µCi/sec. This applies 1% of the Unit 3 Vent release rate limit (see Section II.D.l.a.) to Unit 3 ESF vent releases.
| |
| If effluent conditions from Unit 3 ESF vent releases reach 2,900 µCi /sec, releases from Units 1 and 2 vents, Unit 3 vent and from Units 2 and 3 releases to the Millstone Stack shall be determined to ensure that the sum of the individual noble gas release rates do not cause the site limit to be exceeded. Use Section II.D.l.a. and Section 4.2 of MP-22-REC-REF03, "REMODCM Technical Information Document,"
| |
| in making this determination.
| |
| The Alarm setpoint shall be set at or below the value of 5.9E-4 µCi/cc. This setpoint assumes a monitor flow rate of 10,500 cfm. However, only 6,000 cfm is monitored. By assuming 10,500 cfm the setpoint is conservatively low.

| APPENDIX II.A REMODCM METHODOLOGY CROSS-REFERENCES Radiological effluent controls (Sections III, IV, and V) identify the requirements for monitoring and limiting liquid and gaseous effluents releases from the site such the resulting dose impacts to members of the public are kept to '~ Low As Reasonably Achievable" (ALARA). The demonstration of compliance with the dose limits is by calculational models that are implemented by Section II of the REMODCM.
| |
| Table App. II.A-1 provides a cross- reference guide between liquid and gaseous effluent release limits and those sections of the REMODCM, which are used to determine compliance. It also shows the administrative Technical Specifications which reference the REMO DCM for operation of radioactive waste processing equipment. This table also provides a quick outline of the applicable limits or dose objectives and the required actions if those limits are exceeded. Details of the effluent control requirements and the implementing sections of the REMO DCM should be reviewed directly for a full explanation of the requirements.

| |
| | |
| SECTION III. REMODCM UNIT ONE CONTROLS III.A. Introduction The purpose of this section is to provide the following for Millstone Unit One:
| |
| : a. the effluent radiation monitor controls and surveillance requirements,
| |
| : b. the effluent radioactivity concentration and dose controls and surveillance requirements, and
| |
| : c. the bases for the controls and surveillance requirements.
| |
| Definitions of certain terms are provided as an aid for implementation of the controls and requirements.
| |
| Some surveillance requirements refer to specific sub-sections in Sections I and II as part of their required actions III.B. Definitions and Surveillance Requirement (SR) Applicability III.B.1 - Definitions The defined terms of this sub-section appear in capitalized type and are applicable throughout Section III.
| |
| : 1. ACTION - that part of a Control that prescribes remedial measures required under designated conditions.
| |
| : 2. INSTRUMENT CALIBRATION - the adjustment, as necessary, of the instrument output such that it responds within the necessary range and accuracy to know values of the parameter that the instrument monitors. The INSTRUMENT CALIBRATION shall encompass those components, such as sensors, displays, and trip functions, required to perform the specified safety function(s). The INSTRUMENT CALIBRATION shall include the INSTRUMENT FUNCTIONAL TEST and may be performed by means of any series of sequential, overlapping, or total channel steps so that the entire channel is calibrated.
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 82 of 137
| |
| : 3. INSTRUMENT FUNCTIONAL TEST - the injection of a simulated or actual signal into the channel as close to the sensor as practicable to verify that the instrument is FUNCTIONAL, including all components in the channel, such as alarms, interlocks, displays, and trip functions, required to perform the specified safety function(s). For digital instruments, the computer database may be manipulated, in lieu of a signal injection, to verify operability of alarm and/or trip functions. The INSTRUMENT FUNCTIONAL TEST may be performed by means of any series of sequential, overlapping, or total channel steps so that the entire channel is tested.
| |
| : 4. CHANNEL CHECK - the qualitative determination of functionality by observation of behavior during operation. This determination shall include, where possible, comparison of the instrument with other independent instruments measuring the same variable.
| |
| : 5. FUNCTIONAL - An instrument shall be FUNCTIONAL when it is capable of performing its specified functions(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 instrument to perform its functions(s) are also capable of performing their related support function(s).
| |
| : 6. REAL MEMBER OF THE PUBLIC - an individual, not occupationally associated with the Millstone site, who is exposed to existing dose pathways at one particular location. This does not include employees of the utility or utilities which own a Millstone plant and utility contractors and vendors.
| |
| Also excluded are persons who enter the Millstone site to service equipment or to make deliveries. This does include persons who use portions of the Millstone site for recreational, occupational, or other purposes not associated with any of the Millstone plants.
| |
| : 7. SITE BOUNDARY - that line beyond which the land is not owned, leased, or otherwise controlled by the licensee.
| |
| : 8. SOURCE CHECK - the qualitative assessment of channel response when the channel is exposed to radiation.
| |
| : 9. RADIOACTIVE WASTE TREATMENT SYSTEMS - Radioactive Waste Treatment Systems are those liquid, gaseous, and solid waste systems which are required to maintain control over radioactive materials in order to meet the controls set forth in this section.
| |
| MP-22-REC-BAPOl STOP THINK ACT REVIEW Rev. 029 83 of 137
| |
| | |
| 111.B.2 - Surveillance Requirement (SR) Applicability
| |
| : 1. SRs shall be met during specific conditions in the Applicability for individual LCOs unless otherwise stated in the SR. Failure to meet a Surveillance, whether such failure is experienced during the performance of the Surveillance or between performances of the Surveillance, shall be failure to meet the LCO. Failure to perform a Surveillance within the specified Frequency shall be failure to meet the LCO except as provided in III.B.2 3.
| |
| Surveillances do not have to be performed on nonfunctional equipment or variables outside specified limits.
| |
| : 2. The specified Frequency for each SR is met if the Surveillance is performed within 1.25 times the interval specified in the Frequency, as measured from the previous performance or as measured from the time a specified condition of the frequency is met.
| |
| : 3. If it is discovered that a Surveillance was not performed within its specified frequency, then compliance with the requirement to declare the LCO not met may be delayed from the time of discovery up to 24 hours or up to the limit of the specified frequency, whichever is less. This delay period is permitted to allow performance of the surveillance. If the Surveillance is not performed within the delay period, the LCO must immediately be declared not met and the applicable Condition(s) must be entered. The Completion Times of the Required Actions begin immediately upon expiration of the delay period. When the Surveillance is performed within the delay period and the Surveillance is not met, the LCO must immediately be declared not met and the applicable Condition(s) must be entered. The Completion Times of the Required Actions begin immediately upon failure to meet the Surveillance.
