Controlling liquid effluent to within the MPC values based on an instantaneous release rate (i.e., no time averaging of effluent concentrations) is considered more conservative than the requirements of the new Part 20 which have limits stated as effluent concentrations averaged over a year. In other words, if discharged dissolved and entrained noble gas concentrations remain within the instantaneous concentration limit of 2X 10-4 pCi/ml during the times that discharges actually take place, then there is reasonable confidence that the annual average limits established by the ECL values will also be met. This position is based on a June 30, 1993 letter from Thomas E. Murley (then Director, Office of Nuclear Reactor Regulation) to Thomas E. Tipton of NEI, in which the NRC responded to an industry inquiry on promulgation of a new Part 20.Controls C.6.1.1 and C.5.1 provide controls to ensure that the concentration of radioactive materials released in liquid waste effluents at the point of discharge from the multiport diffuser will be less than the concentration levels specified in 10 CFR 20, Appendix B, Table 2, Column 2.

B.3-1 ODCM Rev. 32 1 | B.3-1 ODCM Rev. 32 1 3.1 Introductory Concepts In Part A Controls, the RECP limits for dose or dose rate are stated. The term "dose" for ingested or inhaled radioactivity means the dose commitment, measured in mrem, which results from the exposure to radioactive materials that, because of uptake and deposition in the body, will continue to expose the body to radiation for some period of time after the source of radioactivity is stopped. The time frame over which the dose commitment is evaluated is 50 years. The phrases "annual dose" or "dose in one year" then refers to the 50-year dose commitment resulting from exposure to one year's worth of releases. "Dose in a quarter" similarly means the 50-year dose commitment resulting from exposure to one quarter's releases.The term "dose," with respect to external exposures, such as to noble gas clouds, refers only to the doses received during the actual time period of exposure to the radioactivity released from the plant. Once the source of the radioactivity is removed, there is no longer any additional accumulation to the dose commitment."Dose rate" is the total dose or dose commitment divided by exposure period. For example, an individual who is exposed via the ingestion of milk for one year to radioactivity from plant gaseous effluents and receives a 50-year dose commitment of 10 mrem is said to have been exposed to a dose rate of 10 mrem/year, even though the actual dose received in the year of exposure may be less than 10 mrem.In addition to limits on dose commitment, gaseous effluents from the station are also controlled so that the maximum or peak dose rates at the site boundary at any time are limited to the equivalent annual dose limits of 10 CFR Part 20 to unrestricted areas (if it were assumed that the peak dose rates continued for one year). These dose rate limits provide reasonable assurance that members of the public, either inside or outside the site boundary, will not be exposed to annual averaged concentrations exceeding the limits specified in Appendix B, Table 2 of 10 CFR Part 20. See Appendix B for a listing of these concentration limits.The quantities AD and f) are introduced to provide calculable quantities, related to off-site doses or dose rates that demonstrate compliance with the RETS.Delta D, denoted AD, is the quantity calculated by the Part B, Chapter 3, Method I dose equations. | ||

The Part A Control indirectly limits peak release rates by limiting the dose rate that is predicted from continued release at the peak rate. By limiting Dskin to a rate equivalent to no more than 3,000 mrem/year, we assure that the skin dose accrued in any one year by any member of the general public is less than 3,000 mrem.Since it can be expected that the peak release rate on which Oskin is derived would not be exceeded without corrective action being taken to lower it, the resultant average release rate over the year is expected to be considerably less than the peak release rate.Use Method I or Method IA first to calculate the Skin Dose Rate from peak release rate via station vents. Method I applies at all release rates.Use Method II if a more refined calculation of I)skin is desired by the station (i.e., use of actual release point parameters with annual or actual meteorology to obtain release-specific X/Qs) or if Method I or Method IA predicts a dose rate greater than the Part A Control limit to determine if it had actually been exceeded during a short time interval. | The Part A Control indirectly limits peak release rates by limiting the dose rate that is predicted from continued release at the peak rate.

ODCM Method I was used initially to confirm dose results from the EMS program. However, the simplified nature of ODCM Method I made it difficult to change the values of various parameters or obtain meaningful comparisons (other than "bottom line" comparisons). | ODCM Method I was used initially to confirm dose results from the EMS program.

The more adaptable ODCH method, Method II, was then used to confirm EMS doses. Observations made during the software testing are summarized below.2.1 EMS Dose and Dose Rate Conversion Factors The EMS software uses precalculated conversion factors which are contained in a data file. The dose conversion factors for both liquid and gaseous effluent releases were developed for four age groups (adult, teen, child and infant), and for specific organs (bone, liver,total body, kidney, lung, GI tract and skin).The liquid release dose conversion factors in the EMS program are the summation of the components for water recreation and ingestion of aquatic foods. The gaseous release dose conversion factors are exposure pathway-specific (e.g., inhalation, ground plane, milk ingestion, etc.).Dose conversion factors are provided in the EMS program for all exposure pathways addressed in the ODCM. The development of all dose conversion factors in the EMS program followed the pathway-specific equations in the Effluent Management System Technical Reference Manual (3]. The EMS conversion factors for several radionuclides were examined to determined that the development process was consistent to the Technical Reference Manual and the ODCM.2 | The more adaptable ODCH method, Method II, was then used to confirm EMS doses.

The mixing ratio for shoreline activity used in the development of the EMS dose factors is equal to 0.025. While this value is inconsistent with ODCH Method I (which employs a mixing ratio of 0.1), it is consistent with ODCM Method II. It is identified as a discrepancy because it is unclear which set of ODCH assumptions (those for Method I or those for Method II)the EMS program is expected to adopt.2.1.2 Gaseous Release Dose Conversion Factors The EMS program uses dose conversion factors from Regulatory Guide 1.109 for assessment of noble gas releases. | The mixing ratio for shoreline activity used in the development of the EMS dose factors is equal to 0.025.

The dose factors in the EMS program were verified against and found to be consistent with Table B-i of Regulatory Guide 1.109 [4].The development methods for the other gaseous dose factors (i.e., for inhalation, ground plane, milk ingestion, meat ingestion, and ingestion of vegetables) were reviewed against applicable equations in the Technical Reference Manual and information in the ODCM. It is noted that the dose factors for ingestion of milk and meat are based on the fraction of year that animals are allowed to graze on pasture land (Fp) equal to 1-0. This is not consistent with the ODCM which calls for the use of an Pp value equal to 0.5.The dose conversion factors in the EMS program for gaseous releases incorporate a shielding factor (SF) equal to 1.0. The EMS program is designed with a way of changing the value of SF (via use of the Options Table), but the factor is applied uniformly to both doses and dose rates. In contrast, the ODCM calls for the use of different values for SF in the calculations for doses and 3 dose rates.2.2 Liquid Release Testing Dose estimates from the EMS program for hypothetical liquid effluent discharges (containing single nuclide and radionuclide mixtures) are nearly identical to results from ODCM Method. II when input data are based on the same mixing ratio value, indicating that the calculation method used in the EMS program is consistent with the ODCM. Additionally, the EMS routine(s) responsible for liquid effluent concentrations comparisons to MPC values and monitor set point determinations was observed to be operating properly.2.3 Caseous Release Testing The agreement between estimates for total body dose rates, skin dose rates, and air (gamma and beta) doses due to emission of noble gases from the ODCH methods and the EMS program is excellent, indicating that the EMS calculation method is consistent with the ODCM.There is also excellent agreement between inhalation doses from the EMS program and ODCK Method II indicating that, for the inhalation pathway, the calculational method and assumptions in the EMS program are consistent with those in the ODCM. The evaluation of the dose estimates via inhalation pathway included both long and short release durations for an elevated (mixed mode) and a ground level release point. The excellent agreement between the EMS and ODCX Method II also confirms that the release duration adjustment term, t-a, is applied properly in the EMS program. However, an incorrect receptor location was reported on the EMS printout in the tests (D-2c and D-2d) in which the Plant Vent was changed to be recognized as a ground level release- point.Also noted during testing was that the EMS routine(s) responsible for calculating effluent concentration-to-MPC ratios and radionuclide release rates 4 appears to be operating properly for gaseous'releases. | The dose factors in the EMS program were verified against and found to be consistent with Table B-i of Regulatory Guide 1.109 [4].The development methods for the other gaseous dose factors (i.e., for inhalation, ground plane, milk ingestion, meat ingestion, and ingestion of vegetables) were reviewed against applicable equations in the Technical Reference Manual and information in the ODCM.

On the other hand, if the EMS program is intended to provide automated ODCM Method I calculations, then the dose factor should be recalculated using a mixing ratio for shoreline activity equal to 0.1.2. Since the EMS program is not designed to support the use of two 0 shielding factors' (one for dose rates and one for doses), use of a shielding factor equal to 1.0 is acceptable with the understanding that, although the dose rates produced by the EMS program will be consistent with the ODCM, the doses from the EMS program will be based on a more conservative assumption than doses from the ODCM methods.3.

*I&2.2. RELEASE PROCESSING For batch releases, the processing of releases consists of sampling the tank or volume of air, analyzing the radionuclide content, then using the radionuclide concentrations and -estimated release flows, volumes, etc. and calculating the doses and setpoints, comparing to the 10CFR20 limits, and comparing to the IOCFR50 limits. If the limits are not exceeded, the pre-release permit is signed off and the release can occur. After the release, post-release processing performs the same calculations (except the setpoints are not needed)and the database is updated with the actual values for the release.For continuous releases, many installations prefer not. to generate an actual pre-release permit, but for the sake of aonalogou's operation, pre-release calculations must still be made in EMs.After review, the post-release calculations are made to update the database.EMS does not allow more that one open release at a time for a single release point. However, multiple releases may be open for one discharge point. Also, for-discharge points, the setpoint is calculated by summing over all open releases for. the time period involved. | *I&2.2.

RMD Controlled Copy SEABROOK STATION PROGRAM MANUAL Offsite Dose Calculation Manual ODCM Rev. 36 Manual Owner: D. A. Robinson ABSTRACT The Offsite Dose Calculation Manual (ODCM) contains details to implement the requirements of Technical Specifications 6.7.6g and 6.7.6h.The Offsite Dose Calculation Manual (ODCM) is divided into two parts: (1) the Radioactive Effluent Controls Program for both in-plant radiological effluent monitoring of liquids and gases, along with the Radiological Environmental Monitoring Program (REMP) (Part A); and (2) approved methods to determine effluent monitor setpoint values and estimates of doses and radionuclide concentrations occurring beyond the boundaries of Seabrook Station resulting from normal Station operation (Part B).The sampling and analysis requirements of the Radioactive Effluent Controls Program, specified in Part A, provide the inputs for the models of Part B in order to calculate offsite doses and radionuclide concentrations necessary to determine compliance with the dose and concentration requirements of the Station Technical Specification 6.7.6g. The REMP required by Technical Specification 6.7.6h, and as specified within this manual, provides the means to determine that measurable concentrations of radioactive materials released as a result of the operation of Seabrook Station are not significantly higher than expected.Revisions to the ODCM require an interdisciplinary review documented on the following page as well as a SORC review prior to implementing the change. An interdisciplinary review includes as a minimum the potential impact the change has on the respective departments' programs and procedures.
The interdisciplinary review shall involve the following departments:
Chemistry, Radiation Protection, I&C, and Operations.
The Originator shall ensure the interdisciplinary reviews are completed prior to the SORC meeting.Page I of 2 ODCM Rev. 30 1 Interdisciplinary Review ODCM Rev.

1.0 INTRODUCTION
The Offsite Dose Calculation Manual (ODCM) contains details to implement the Radioactive Effluent Controls and Environmental Monitoring Programs" of Technical Specifications 6.7.6g and 6.7.6h.The purpose of this manual is to contain details for the implementation of the Radioactive Effluent Technical Requirement Program (RETRP) and the Radiological Environmental Monitoring Program (REMP). These programs are required by Technical Specifications 6.7.6g and 6.7.6h.Part A of this manual defines specific concentrations, sampling regimes and frequencies for both the RETRP and the REMP. These activities are the defined surveillances for radiological releases.
Part A also defines specific sampling locations for the RETRP. The information contained in Part A is used as input into the models that are used in Part B. The Part B models identify the calculational methods for determining radiation monitor setpoints, offsite doses and effluent concentrations of radionuclides.
Part B also defines sampling locations for the REMP.The data resulting from the surveillance and monitoring programs described in Part A provide a means to confirm that concentrations of radioactive material released, as a result of routine Seabrook Station operations, do not contribute to effluent dose significantly different than as postulated in Part B.An ODCM Surveillance Requirement may be considered met if surveillance is performed within 1.25 times the stated surveillance interval.
This 25% extension facilitates surveillance scheduling and considers plant operating conditions that may not be suitable for conducting the surveillance test. This provision is not intended to be used repeatedly merely as an operational convenience to extend surveillance intervals beyond those specified.

The Alarm/Trip Setpoints of these channels shall be determined and adjusted in accordance with the methodology and parameters in the OFFSITE DOSE CALCULATION MANUAL (ODCM), Part B.APPLICABILITY:
At all times.ACTION: a. With a radioactive liquid effluent monitoring instrumentation channel Alarm/Trip Setpoint less conservative than required by the above specification, immediately suspend the release of radioactive liquid effluents monitored by the affected channel, or declare the channel inoperable.
- b. With less than the minimum number of radioactive liquid effluent monitoring instrumentation channels OPERABLE, take the ACTION shown in Table A.5.1-1.Restore the inoperable instrumentation to OPERABLE status within a time period determined by an evaluation conducted in accordance with the requirements of the Corrective Action Program. An evaluation is not required if the noncompliance is a consequence of surveillance testing or planned maintenance.
SURVEILLANCE REQUIREMENTS S.5.1 Each radioactive liquid effluent monitoring instrumentation channel shall be demonstrated OPERABLE by performance of the CHANNEL CHECK, SOURCE CHECK, CHANNEL CALIBRATION, and CHANNEL OPERATIONAL TEST at the frequencies shown in Table A.5.1-2.BASES 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 and adjusted in accordance with the methodology and parameters in the ODCM to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20. The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50.A.5-1 ODCM Rev. 34 Table A.5.1-2 Item 3a of Control C.5.1 requires that a Channel Operational Test be performed on the radioactivity monitors (RM-R-6515 and RM-R-6516) for the PCCW System. This channel operational test is a digital channel operational test and requires that it shall demonstrate automatic isolation of the pathway and control room alarm annunciation.
For Seabrook Station, these two radioactivity monitoring channels provide control room annunciation, but do not provide automatic isolation of the release pathway. This particular item was discussed in detail with the NRC staff reviewers.
For this particular reason, the words "But Not Termination of Release" were added to Item 3 of Table A.5.1-2. The purpose of adding the above words to Item 3 was to preclude the addition of another Table Notation to Table A.5.1-2. Therefore, the channel operational test for these monitors only requires that they provide control room alarm annunciation.
The CHANNEL CHECK for Flow Rate Measurement Devices (Table A.5.1-2, items 2.a., 2.b. and 2.d.) is required "at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> on days when continuous, periodic, or batch releases are made." Additionally, ACTION 31 of Table A.5.1-1 is only applicable during actual releases.Based on the above requirements, these instruments are only required to be OPERABLE during actual releases.
Therefore, the CHANNEL CHECK is only required during periods when continuous, periodic, or batch releases are being made.The Primary Component Cooling Water (PCCW) System is monitored by radiation monitors, which are required by Technical Specifications 3.3.3.1 and ODCM C.5.1 to be OPERABLE, or sampling of the PCCW and Service Water (SW) Systems is required.
Clarification of this requirement needs to be made for certain PCCW System conditions.
Below is a list of 3 conditions and their corresponding requirements.
- 1) If the PCCW System is shut down but not drained, grab samples shall be taken of PCCW and SW, as required in Technical Specification Table 3.3-6, Items 6a and 6b (Action 28).2) During transition times when the PCCW system is in the process of being drained, grab samples, as required by Technical Specification Table 3.3-6 and ODCM C.5.1, shall be taken until such time as sampling of PCCW is no longer possible.
At this time neither PCCW nor SW need to be sampled. During transition times when the PCCW system is being filled, the taking of grab samples shall commence as soon as physically possible and continue in accordance with the requirements of Technical Specifications 3.3.3.1 and ODCM C.5.1 until PCCW is in service, the pumps are operating, and monitors are operable..3) When PCCW is drained, there are no sampling requirements.
The above statements are consistent with the Technical Specification definition of OPERABILITY and with the Bases for Technical Specification 3.3.3.1.A.5-2 ODCM Rev. 34 The following actions are required when the Service Water side of the Primary Component Cooling Water (PCCW) Heat Exchanger is drained and grab samples of the Service Water System are required: a. Grab samples from the Service Water System will be obtained at the frequencies specified in Technical Specification 3.3.3.1 and ODCM C.5.1 as the Service Water System is being drained until obtaining these samples is not physically possible.b. Grab samples are not required once the Service Water System is drained such that it is not physically possible to obtain the samples.c. When refilling the Service Water System, grab samples shall resume as soon as physically possible, at the intervals specified in the aforementioned sources, and continue until the PCCW radiation monitors (1-RM-6515 and 1-RM-6516) are OPERABLE.Sampling of the PCCW system with the Service Water system drained and the PCCW system in operation shall continue per the requirements of Technical Specification 3.3.3.1 and this Control.The purpose of the plant radiation monitors is to sense radiation levels in selected plant systems and locations and determine whether or not predetermined limits are being exceeded.
In the case of the Primary Component Cooling Water (PCCW) loops, the radiation monitors (1-RM-6515 and 1-RM-6516) sense radiation in the PCCW system which could leak into the Service Water System and be discharged to the environment via the multiport diffuser.
Per Control C.6. 1.1, the concentration of radioactive material released in liquid effluents at the point of discharge from the multiport diffuser must be within specified limits. This limitation provides assurance that the levels of radioactive materials in unrestricted areas will not pose a threat to the health and safety of the public.Based on the importance of maintaining radioactive effluent releases within limits that guarantee the health and safety of the public will not be at risk, the PCCW radiation monitors are required to be in operation at all times. When a radiation monitor is inoperable, grab samples from the PCCW and Service Water systems must be obtained and analyzed as a compensatory measure in accordance with Technical Specification 3.3.3.1, Table 3.3-6 Action 28 and this Control. If the service water system is drained, there is no potential for inadvertent radioactive liquid effluent release through the service water system to the environment via the multiport diffuser.
Thus, when the system is drained there is no need to obtain the grab sample. However, when the system is being filled, grab samples must be obtained as soon as possible to ensure that the water discharged to the environment is in compliance with Control C.6. 1.1.The purpose of the PCCW monitors is to detect radioactivity indicative of a leak from the Reactor Coolant System or from one of the other radioactive systems which exchange with the PCCW System. These monitors are required to be operable at all times. Grab samples of PCCW are required when the PCCW monitors are not operable.
Since the purpose of obtaining the PCCW samples is to provide an indication of a leak of radioactive liquid into the PCCW system, draining of the Service Water system does not remove the reason for obtaining the PCCW grab samples. These samples shall be obtained as specified in Technical Specification 3.3.3.1 and this Control. This determination is consistent with the Bases for Technical Specification 3.3.3.1.The temporary lowering of an RDMS channel setpoint, by RDMS data base manipulation to verify alarm/trip functions, does not prevent the channel from continuously monitoring radiation levels (except for the WRGM DCOT due to low and high activity sample flow paths). Additionally, when the setpoint is lowered below background radiation levels the associated trip functions will actuate equipment in their required operating mode as if a high radiation condition exists. The channel remains OPERABLE because monitoring and associated trip functions are not inhibited.
A.5-3 ODCM Rev. 34 When the SGBD demineralizers are being rinsed to the ocean using SGBD water, the SGBD flash tank radiation monitor (RM-6519) may become inoperable in this alignment from decreased backpressure to run the monitor sample pump. If this happens, the sampling requirements of Table A.5.1-1 ACTION 30 must be performed.
RM-6509, although in the flowpath of the SGBD demineralizer rinse, cannot perform the function of RM-6519 because it cannot achieve the same sensitivity to radiation.
However, RM-6509 shall have its setpoints established per plant procedures since the discharge flow path is through the SGBD demineralizers (where a potential to acquire radioactivity exists), but after RM-6519.If RM-6509 is inoperable, then in addition to the periodic sampling requirements of Table A.5.1-1 ACTION 30 for RM-6519, the batch sample and lineup verification of ACTION 29 would also have to be complied with, for RM-6509.It should be noted that, during a SGBD demineralizer rinse to the discharge transition structure with SB liquid, SB-FE-1918 is not in the flow path. It is acceptable to use a flow monitoring device in the final flow path (such as WL-FIT-1458) so that Table A.5.1-1 ACTION 31 does NOT have to be entered.During power operations, SGBD demineralizer effluent is normally aligned to the Main Condenser Hotwell for water recovery.
However, following SGBD / SGBD demineralizer system maintenance, or for plant operational requirements, the system effluent can be aligned to the Turbine Building Sump to maintain secondary chemistry and plant related parameters.
When SGBD demineralizer effluent is aligned to the Turbine Building Sump, the effluent to Outfall 001 is monitored by RM-652 1. The Turbine Sump Radiation Monitor RM-6521, although in the flow path of the SGBD demineralizer effluent, cannot perform the alarm and trip function of the SGBD Flash Tank Monitor RM-6519 because it cannot achieve the same sensitivity to radiation.
However, RM-6521 shall have its set points established per plant procedures since the discharge flow path is through the SGBD demineralizers (where a potential to acquire radioactivity exist), but after passing through RM-6519. If either RM-6519 or RM-6521 is inoperable, then the periodic sampling requirements of Table A.5.1-1 Action 30 apply. It should be noted that when SGBD demineralizer effluent is aligned to the Turbine Building Sump, flow indicator SB-FE-1918 is not in the flow path. It is acceptable to use a flow monitoring device in the final flow path (such as DF-FT-5957) so that Table A.5.1-1 ACTION 31 does NOT have to be met.Steam generators may be drained using the wet lay-up pumps directly to the circulating water system, if no secondary steam pressure is available and provided the steam generator(s) liquid radioactivity is less than both 10 CFR 20 (Appendix B, Table 2, Column 2 instantaneous release);
and 10 CFR 50 Appendix I (annual release).
Table A.5.1-1 Actions 30 and 31 apply in this case as both the radiation monitor (RM-RM-6519) and the flow rate monitor (SB-FE-1918) are bypassed.The Note which corresponds to Table A.5.1-1 "**" states that pump performance curves generated in place "should" be used to estimate flow. Hence, there is no requirement to use the pump curves as described in these tables.A.5-4 ODCM Rev. 34 TABLE A.5.1-1 RADIOACTIVE LIQUID EFFLUENT MONITORING INSTRUMENTATION MINIMUM CHANNELS OPERABLE ACTION INSTRUMENT

The Alarm/Trip Setpoints of these channels meeting Control C.7. 1.1 shall be determined and adjusted in accordance with the methodology and parameters in the ODCM (Part B).APPLICABILITY:
As shown in Table A.5.2-1.ACTION: a. With a radioactive gaseous effluent monitoring instrumentation channel Alarm/Trip Setpoint less conservative than required by the above specification, immediately suspend the release of radioactive gaseous effluents monitored by the affected channel, or declare the channel inoperable.
- b. With the number of OPERABLE radioactive gaseous effluent monitoring instrumentation channels less than the Minimum Channels OPERABLE, take the ACTION shown in Table A.5.2-1. Restore the inoperable instrumentation to OPERABLE status within a time period determined by an evaluation conducted in accordance with the requirements of the Corrective Action Program. An evaluation is not required if the noncompliance is a consequence of surveillance testing or planned maintenance.
SURVEILLANCE REQUIREMENTS S.5.2 Each radioactive gaseous effluent monitoring instrumentation channel shall be demonstrated OPERABLE by performance of the CHANNEL CHECK, SOURCE CHECK, CHANNEL CALIBRATION and CHANNEL OPERATIONAL TEST at the frequencies shown in Table A.5.2-2.BASES 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 and adjusted in accordance with the methodology and parameters in the ODCM (Part B) to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20. The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50. The sensitivity of any noble gas activity monitors used to show compliance with the gaseous effluent release requirements of Control C.7.2.1 shall be such that concentrations as low as 1 X 10-6 liCi/cc are measurable.
A.5-11 ODCM Rev. 34 The main condenser air evacuation radiation monitor, RM-6505, is included with the Turbine Gland Seal Condenser Exhaust in Tables A.5.2-1 and A.5.2-2. Table A.5.2-1 defines the minimum channels operable and the required actions for the radioactive gaseous effluent monitoring instrumentation.
Table A.5.2-2 lists the surveillance requirements for this instrumentation.
The Plant Vent Wide Range Gas Monitor (WRGM) design includes three ranges of noble gas monitors and two ranges of iodine and particulate sampling filters. The noble gas monitor, the equipment necessary to provide flow through three ranges of the noble gas monitors, and the iodine and particulate sample filters all affect the operability of the WRGM. The various combinations of out-of-service components are addressed in this clarification.
The WRGM noble gas activity monitor has three overlapping detector ranges: low, mid, and high.UFSAR Table 12.3-15 lists the following ranges for the WRGM: Low Range 10- 1 tCi/cc Mid Range 10- -10 3 High Range 10 10 5 The minimum number of operable channels for the noble gas activity monitor, the flow rate monitors and the iodine sampler and particulate sampler is one, respectively.
The Controls do not list the specific WRGM noble gas activity monitor, the iodine/particulate sampler or the flow rate monitor channels separately by an instrumentation identification tag number.Heat tracing of the sample lines, from the plant vent to the WRGM, is not listed as a specific requirement for WRGM operability.
However, these circuits are necessary to ensure that the particulate and iodine concentration of the sample reaching the WRGM is representative of the effluent.
The purpose of heat tracing is to ensure that the sample lines are free of moisture due to condensation.
The low temperature alarm setpoint is variable based on outside ambient air temperature, and ensures that the sample line tubing metal temperature is high enough to prevent the moisture in the air from condensing inside of the sample line. The ability to detect of noble gases is not affected by the operational status of the heat tracing circuits.The heat tracing on the sample lines within the PAB (CP 433, circuit 55) is not required for WRGM operation. (Engineering Evaluation, SS-EV-960017 and MMOD 02-0531)The following equipment normally defines an operational WRGM: During routine releases,-Sample flow through one of the particulate and iodine (P&I) filters F-156-1,2,3 and channel 1 (low range) noble gas (NG) detectors using pump P-240-2, and-Sample flow through P&I filters F-156-7,8 using pump RM-P-391.or in the event the noble gas activity is in the mid/high range,-Sample flow through one of the particulate/iodine (P&I) filters F-156-4,5,6 and channels 2 or 3 (mid/high range) NG detectors using pump P-240-1, and-Sample flow bypassing P&I filters F-156-7,8 using pump RM-P-391.A.5-12 ODCM Rev. 34 At all times,-Heat tracing (HT) on the sample lines from the plant vent to the WRGM.Note: Dewpoint measurements may be used if heat tracing is out of service. (See the following table)-Vent stack flow rate monitor.-WRGM sample flow rate for the channel(s) in service.The table below lists the action required in the event that a WRGM component is out of service.Out of Service Comoonent Action Low range NG detector High range NG detector Mid range NG detector RM-P-391 Enter Action 33. Perform grab sampling as required.Enter Action 33. The actions required by Action 33 are satisfied provided the Low range NG detector provides continuous indication of the effluent concentrations, grab sampling not required.
In the unlikely event that elevated effluent concentrations above the capability of the low range detector are present, then grab sampling or backup monitoring will/may be required.No action required, detection capability met by the overlapping ranges of the low and high NG detectors. (May need to ensure that the high range pump [RM-P-240-1]
starts on increasing activity.)
Enter Action 35. The mid and high range particulate and iodine sampling capability is lost. If a low range P&I filter F-156-1,2 or 3 is in service then no further action is required.
If the low range P&I filters are out of service then comply with Action 35 within one hour.Enter Actions 32, 33 and 35. Action 33 is satisfied provided the low range NG detector provides continuous indication of the effluent concentrations, grab sampling is not required.
Actions 32 and 35 are satisfied ifP-240-2, and filters F-156-1,-2, or -3 are in service. If these P&I filters are out of service and the NG activity is in the low range, then ensure compliance with Actions 32 and 35 within one hour of identifying the out of service condition.
In the unlikely event that elevated effluent concentrations above the capability of the low range detector are present, then, with P-391 operating, install a portable sample pump across valves V28 and V29 to facilitate P&I grab sampling using filters F-156-4,-5, or -6, and noble gas sampling using the medium and high range detectors.
P-240-1 (High range pump)A.5-13 ODCM Rev. 34 P-240-2 (Low range pump)HT circuit: CP-434 Ckt 28.(Sample line temperature less than 20'F above ambient as indicated by computer points B5946 / B5948.)Flow rate monitor and/or sampler flow rate monitor.Enter Actions 32, 33 and 35. Action 33 is satisfied by performing grab samples. Actions 32 and 35 are satisfied by ensuring one of the following sample configurations are in service within one hour of identifying the out-of-service condition; the operation of P-391 with filters F-156-7 & 8,or installing a portable sample pump across valves V2, and V5 to facilitate P&I grab sampling.Enter Action 36. Action 36 is satisfied and the WRGM may remain OPERABLE with CP-434 Ckt 28 out of service provided that CP-426 Ckt 46 is energized within 1 hr of the out-of-service condition.
If the sample line temperature can not be maintained greater than or equal to 207F above ambient, the particulate and iodine samples remain valid provided moisture is not present.Action 36 provides moisture monitoring capability.
Comply with Action 32.Action Statement 35 provides no guidance with regard to time required to initiate auxiliary sampling upon failure of a monitor. A finite time is required to take the appropriate actions to initiate auxiliary sampling.An interval of 60 minutes is a reasonable period of time in which to accomplish these actions provided that no activity occurs during this period which could result in an increase in radiation release levels.Since the intent of Action 35 is to allow continued release of gaseous effluents provided an alternate means of continuous monitoring/collection capability is on-going during the release of radioactive gaseous effluents, the 60 minute time frame for auxiliary sampling to be established is still a reasonable period of time to complete the necessary manual actions to establish auxiliary sampling.
If auxiliary sampling cannot be established within 60 minutes then the initial action of immediately suspending the release of radioactive gaseous effluents should be done, as specified in Action a. of C.5.2. It should be noted that for lack of specified criteria the 60-minute time period is solely based on prudent engineering judgment for completion of manual actions in order to satisfy the intent of Action 35. Operation beyond 60 minutes without auxiliary sampling service would need to be justified by engineering calculation to ensure continued compliance with 10 CFR Part 20 limits.On those occasions when a radiation monitor or any system/component must be rendered inoperable to perform a surveillance test, the Station Management Manual (SSMM) policy regarding "the use of ACTION requirements to perform maintenance or a test" applies.A.5-14 ODCM Rev. 34 When a surveillance test must be performed on the WRGM, rendering it inoperable, Action 35 cannot be fully satisfied because of the nature of testing is incompatible with the Action 35 required installation of auxiliary sampling equipment.
However, because the performance of the WRGM surveillance renders it inoperable for only a short period of time (e.g., less than one hour), it is reasonable to allow the surveillance test to be performed without the installation of the auxiliary sampling equipment.
It should be noted that neither C.5.2 Action a. nor Action b. requires the immediate establishment of auxiliary sampling.However, if there is concern that the results of surveillance testing activities will identify the instrumentation as inoperable then it would be prudent to set up the auxiliary sampling equipment prior to surveillance testing. The prudent action would prevent the potential situation of continued release of gaseous effluents beyond 60 minutes without continuous monitoring/collection capability.
A procedural method of collecting the grab sample from the plant vent release pathway may require the shutdown of the compensatory sampling equipment pump (for pressure equilibrium purposes) whenever a grab sample is to be withdrawn into the sample bottle. Shutting down the pump raises the question as to whether this action contradicts the "continuous collection" requirement of Action 35.Action 35 allows effluent releases to continue provided samples are continuously collected (as required in Table A.7.1-1) with auxiliary equipment whenever the number of channels OPERABLE is less than the Minimum Channels OPERABLE requirement.
Table A.7. 1-1 requires that the sampling frequency be continuous for iodine and particulate and a monthly grab sample for noble gasses (Kr and Xe). Action 32 supports Action 35 by providing periodic sample flow rate monitoring for use in the iodine and particulate activity determinations.
The ODCM also requires that the ratio of the sample flow rate to the sampled stream flow rate be known/determined for the time period covered by each dose or dose rate calculation made in accordance with C.7.1.1, C.7.2.1, and C.7.3.1 (i.e., weekly and/or monthly).It must be noted that Actions 32 and 35 pertain to the iodine and particulate samplers.
For noble gas collection, Action 33 is applicable which requires grab samples be taken once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and analyzed for radioactivity within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Action 33 does not specify that auxiliary sampling for noble gas must be continuous; therefore, the concern for "continuous" monitoring/collection is not applicable for auxiliary sampling of noble gas.Whenever the station is operating under the auspices of Action 35 the process of collecting grab samples by the auxiliary sampling method necessitates, on occasions, the temporary disablement of permanent and/or temporary equipment (e.g., installation, and disconnection of auxiliary sampling equipment, pressure equalization, etc.) in order to achieve and comply with the requirements of Action 35. Therefore, actions required (e.g. temporarily shutting down the sample pump in order to install / remove / equalize sample bottles, thus interrupting continuous flow) to obtain a grab sample are not considered actions that are contrary in meeting the intent of Action 35.The temporary lowering of an RDMS channel setpoint, by RDMS data base manipulation to verify alarm/trip functions, does not prevent the channel from continuously monitoring radiation levels (except WRGM). Additionally, when the setpoint is lowered below background radiation levels the associated trip functions will actuate equipment in their required operating mode as if a high radiation condition exists.The channel remains OPERABLE because monitoring and associated trip functions are not inhibited.
Therefore, during performance of a RDMS channel DCOT, the LCO remains satisfied.
Entering an ACTION statement is not appropriate nor required (except for WRGM DCOT due to low and high activity sample flow paths). However, because the channel is in alarm status, increased operator vigilance is required to note any increase in radiation levels during the DCOT surveillance period and to take remedial actions if required.A.5-15 ODCM Rev. 34 C.5.2 ACTION Statement
- 33 is applied if RM-6504 is inoperable.
The intent of the last sentence is that RM-6503 may be used instead of taking a grab sample. It is not intended that RM-6503 be used in place of or as an alternate to RM-6504 and ACTION Statement
- 33 not entered. If RM-6503 were considered an alternate for RM-6504 then operations could continue indefinitely without the ability to automatically terminate a radiological release. This is clearly not the intent of C.5.2 ACTION Statement
- 33.RM-6504 monitors the radiation level of the gas stream at the outlet of the waste gas compressors.
If a high radiation level is detected, RM-6504 automatically closes WG-FV-1602.
The closing of WG-FV-1602 isolates a potential radiological release path to the environment.
RM-6503, located at the inlet to the waste gas compressor, provides alarm and monitoring functions only. It does not have the ability to terminate a radiological release. Therefore, it cannot be used as a substitute for RM-6504.Table A.5.2-1, Radioactive Gaseous Effluent Monitoring Instrumentation, specifically lists RM-6504 as the instrument required to satisfy the Limiting Condition for operation.
This table also states that the monitor provide the functions of alarm and automatic termination of release.A.5-16 ODCM Rev. 34 TABLE A.5.2-1 RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION MINIMUM CHANNELS OPERABLE INSTRUMENT

For subsequent channel calibrations, sources that have been related to the initial calibration shall be used.(4) (Not Used).(5) The CHANNEL CALIBRATION shall be performed using sources of various activities covering the measurement range of the monitor to verify that the response is linear. Sources shall be used to verify the monitor response only for the intended energy range.A.5-20 ODCM Rev. 34 6.0 RADIOACTIVE LIQUID EFFLUENTS 6.1 Concentration CONTROLS C.6. 1.1 The concentration of radioactive material released in liquid effluents at the point of discharge from the multiport diffuser (see Technical Specifications Figure 5.1-3) shall be limited to not more than ten times the concentrations specified in 10 CFR Part 20, Appendix B, Table 2, Column 2, for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2 X 1 0-4 1Ci/ml total activity.APPLICABILITY:
At all times.ACTION: With the concentration of radioactive material released in liquid effluents at the point of discharge from the multiport diffuser exceeding the above limits, restore the concentration to within the above limits within 15 minutes.SURVEILLANCE REQUIREMENTS S.6.1.1 Radioactive liquid wastes shall be sampled and analyzed according to the sampling and analysis program specified in Table A.6.1-1.S.6.1.2 The results of the radioactivity analyses shall be used in accordance with the methodology and parameters in Part B of the ODCM to assure that the concentrations at the point of release are maintained within the limits of Control C.6.1. l.BASES This Control is provided to ensure that the concentration of radioactive materials released in liquid waste effluents at the point of discharge from the multiport diffuser will be less than the concentration levels specified in 10 CFR Part 20, Appendix B to 20, Table 2, Column 2 (most restrictive).
This limitation provides additional assurance that the levels of radioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within (1) the Section H.A design objectives of Appendix I, 10 CFR Part 50, to a MEMBER OF THE PUBLIC, and (2) the limits of Appendix I, 10 CFR 20.1301 and 20.1302 to the population.
Those values assure a continuous discharge at those concentrations (8760 hours0.101 days <br />2.433 hours <br />0.0145 weeks <br />0.00333 months <br /> per year). Pursuant to the requirements of 10 CFR 50.36a to maintain effluent concentrations as low as reasonably achievable (ALARA), Appendix I tolO CFR 50 specifies dose values that are a small percentage of the dose limits in 10 CFR 20.1301. Consistent with Appendix I tolO CFR 50, to allow operational flexibility, this specification in conjunction with the dose specification in Section C-6.2 permits an instantaneous concentration release rate up to a factor often times greater than specified in 10 CFR 20, Appendix B, Table 2, Column 2 while continuing to limit the total annual discharge to a small fraction of the allowable annual dose as specified in Appendix I.A.6-1 ODCM Rev. 33 I The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radioisotope and its MPC in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication
- 2. For technical requirements associated with the release of liquid effluent, the method currently in use for controlling releases of dissolved and entrained noble gases is suitable for demonstrating conformance to the requirements of the "new" 10 CFR 20, Appendix B ECL concentration limits because the 2X10-4 .Ci/ml criterion is based on the "old" MPC value for Xe-135 as the driving radionuclide.
Controlling liquid effluent to within the MPC values based on an instantaneous release rate (i.e., no time averaging of effluent concentrations) is considered more conservative than the requirements of the new Part 20 which have limits stated as effluent concentrations averaged over a year. In other words, if discharged dissolved and entrained noble gas concentrations remain within the instantaneous concentration limit of 2X 10-4 pCi/ml during the times that discharges actually take place, then there is reasonable confidence that the annual average limits established by the ECL values will also be met. This position is based on a June 30, 1993 letter from Thomas E. Murley (then Director, Office of Nuclear Reactor Regulation) to Thomas E. Tipton of NEI, in which the NRC responded to an industry inquiry on promulgation of a new Part 20.Controls C.6.1.1 and C.5.1 provide controls to ensure that the concentration of radioactive materials released in liquid waste effluents at the point of discharge from the multiport diffuser will be less than the concentration levels specified in 10 CFR 20, Appendix B, Table 2, Column 2. As no LLD is specified for the compensatory samples taken for an inoperable PCCW Head Tank Rate of Change Monitor, the LLD for these samples must ensure that these limits are met.Although the periodic Service Water System sample is counted to an LLD of 5xl 0-7 gCi/cc, the compensatory samples for inoperable SGBD Flash Tank and Turbine Building Sump Monitors are required to be counted to an LLD of I xl0-7 pCi/cc. This more restrictive limit will ensure that the limits of 10 CFR 20 are met during periods of PCCW Head Tank Rate of Change Monitor inoperability, thereby ensuring compliance with the requirements of the respective Controls.Counting the required grab samples to an LLD of lx1 0-7 tCi/cc is therefore an acceptable method of complying with these requirements; it is not necessary to meet the LLD of lxlO-8[tCi/cc specified as the equivalent sensitivity of the PCCW Head Tank Rate of Change Monitor.A.6-2 ODCM Rev. 33 I TABLE A.6.1-1 RADIOACTIVE LIOUID WASTE SAMPLING AND ANALYSIS PROGRAM Lower Limit of Minimum Analysis Detection Liquid Release Type Sampling Frequency Frequency Type of Activity Analysis (LLD) (')(PCi/ml)A. 1.

Notations (1) The LLD is defined, for purposes of these specifications, as the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be detected with 95 percent probability with only 5 percent 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 x V x 2.22 x 106 x Y x exp (-AA t)Where: LLD = the "a priori" lower limit of detection (microcurie per unit mass or volume), 4.66 = a constant derived from the Kalpha and Kbeta values for the 95% confidence level;Sb the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (counts per minute), E = the counting efficiency (counts per disintegration), V = the sample size (units of mass or volume), 2.22 x 106 = the number of disintegrations per minute per microcurie, Y the fractional radiochemical yield, when applicable, A = the radioactive decay constant for the particular radionuclide (s-1), and A t = the elapsed time between the midpoint of sample collection and the time of counting(s).
Typical values of E, V, Y, and A t should be used in the calculation.
It should be recognized that the LLD is defined as an a prori (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.
(2) A batch release is the discharge of liquid wastes of a discrete volume. A batch discharge that is interrupted and reinitiated at a later time with no additional input (verified input isolated) is considered to be one release. Prior to sampling for analyses, each batch shall be isolated, and then thoroughly mixed to assure representative sampling.A.6-6 ODCM Rev. 33 I TABLE A.6.1-1 RADIOACTIVE LIQUID WASTE SAMPLING AND ANALYSIS PROGRAM (Continued)
Notations (Continued)
(3) The principal gamma emitters for which the LLD specification applies include 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 considered.
Other gamma peaks that are identifiable, together with those of the above nuclides, shall also be analyzed and reported in the Annual Radioactive Effluent Release Report in accordance with Technical Specification 6.8.1.4. Isotopes which are not detected should be reported as "not detected." Values determined to be below detectable levels are not used in dose calculations.
(4) 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 that is representative of the liquids released.(5) A continuous release is the discharge of liquid wastes of a nondiscrete volume, e.g., from a volume of a system that has an input flow during the continuous release.(6) Sampling and analysis is only required when Steam Generator Blowdown is directed to the discharge transition structure.
During plant operation in Modes 1 through 4, Steam Generator Blowdown Flash Tank releases are considered continuous releases (sampled prior to or during the release) due to the potential input from primary to secondary system leakage during discharges.-
During plant outages (Modes 5 and 6), Steam Generator drains are considered as batch type releases (input isolated, recirculated and sampled prior to release).(7) Principal gamma emitters shall be analyzed weekly in Service Water. Sample and analysis requirements for dissolved and entrained gases, tritium, gross alpha, strontium 89 and 90, and Iron 55 shall only be required when analysis for principal gamma emitters exceeds the LLD for other than naturally occurring radioactivity.
The following are additional sampling and analysis requirements:
- a. PCCW sampled and analyzed weekly for. principal gamma emitters.b. Sample Service Water System (SWS) daily for principal gamma emitters whenever primary component cooling water (PCCW) activity exceeds 1 x1 0-3 [LC/cc.c. With the PCCW System radiation monitor inoperable, sample PCCW and SWS daily for principal gamma emitters.d. With a confirmed PCCW/SWS leak and PCCW activity in excess of lx10-4 ptC/cc, sample SWS every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for principal gamma emitters.A.6-7 ODCM Rev. 33 I TABLE A.6.1-1 RADIOACTIVE LIQUID WASTE SAMPLING AND ANALYSIS PROGRAM (Continued)
Notations (Continued)
- e. The setpoint on the PCCW head tank liquid rate-of-change alarm will be set to ensure that its sensitivity to detect a PCCW/SWS leak is equal to or greater than that of an SWS radiation monitor, located in the unit's combined SWS discharge, with an LLD of lxl0--tgC/cc.
If this sensitivity cannot be achieved, the SWS will be sampled once every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.(8) If the Turbine Building Sump, Steam Generator Blowdown Flash Tank, Steam Generator Blowdown Demineralizer Megarinse, or Condensate Polishing Demineralizer Megarinse discharges isolate due to high concentration of radioactivity, that liquid stream will be sampled and analyzed for Iodine-131 and principal gamma emitters prior to release.(9) Quarterly composite analysis requirements shall only be required when analysis for principal gamma emitters indicate positive radioactivity other than naturally occurring.
(10) A grab sample can be considered as a combination of aliquots taken from each SW train during the same collection cycle or as individual samples taken from each train in service.() Principal gamma emitters and tritium shall be analyzed monthly in subsurface dewatering samples. Sample and analysis requirements for gross alpha, strontium 89 and 90, and Iron 55 shall only be required when analysis for principal gamma emitters exceeds the LLD.for other than naturally occurring radioactivity.
(12) Condensate Polishing Demineralizer or Steam Generator Blowdown Megarinse water shall be sampled and analyzed for principal gamma emitters and 1-131 prior to initiation of the megarinse discharge to the circulating water system.(13) The Storm Drain System is not designed as a pathway for plant related liquid effluent waste releases.
Storm drains are routinely used as the plant subsurface de-watering, secondary steam trap condensation and auxiliary boiler liquid release pathway to the circulating water system.Incidental releases from other sources that contain insignificant quantities of radioactivity may enter and use the storm drain system as a pathway to the circulating water system. Principal gamma emitters and tritium shall be analyzed for weekly. Sample and analysis requirements for gross alpha, strontium 89 and 90, and Iron 55 shall only be required when analysis for principal gamma emitters exceeds the LLD for other than naturally occurring radioactivity, from an unidentified source.(14) The Condensate Polishing System (CPS) has the provision to discharge temporary tanks as batch releases through the same discharge path as the Neutralization Tank (TK-32). The requirements for discharges from a temporary tank through this CPS pathway are equivalent to those of the Neutralization Tank.A.6-8 ODCM Rev. 33 1 6.2 Dose CONTROLS C.6.2.1 The dose or dose commitment to a MEMBER OF THE PUBLIC from radioactive materials in liquid effluents released, from each unit, to UNRESTRICTED AREAS (see Technical Specification Figure 5.1-3) shall be limited a. During any calendar quarter to less than or equal to 1.5 mrems to the whole body and to less than or equal to 5 mrems to any organ, and b. During any calendar year to less than or equal to 3 mrems to the whole body and to less than or equal to 10 mrems to any organ.APPLICABILITY:
At all times.ACTION: With the calculated dose from the release of radioactive materials in liquid effluents exceeding any of the above limits, prepare and submit to the Commission within 30 days, pursuant to Technical Specification 6.8.2, a Special Report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions that have been taken to reduce the releases and the proposed corrective actions to be taken to assure that subsequent releases will be in compliance with the above limits.SURVEILLANCE REQUIREMENTS S.6.2.1 Cumulative dose contributions from liquid effluents for the current calendar quarter and the current calendar year shall be determined in accordance with the methodology and parameters in Part B of the ODCM at least once per 31 days.A.6-9 ODCM Rev. 33 I BASES This Control is provided to implement the requirements of Sections II.A, III.A, and [V.A of Appendix I to 10 CFR Part 50. The Control implements the guides set forth in Section H.A of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents to UNRESTRICTED AREAS will be kept as low as is reasonably achievable.
The dose calculation methodology and parameters in the ODCM 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 equations specified in the ODCM 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.A.6- 10 ODCM Rev. 33 1 6.3 Liquid Radwaste Treatment System CONTROLS C.6.3.1 The Liquid Radwaste Treatment System shall be OPERABLE and appropriate portions of the system shall be used to reduce releases of radioactivity when the projected doses due to the liquid effluent to UNRESTRICTED AREAS (see Technical Specification Figure 5.1-3)would exceed 0.06 mrem to the whole body or 0.2 mrem to any organ in a 31-day period.APPLICABILITY:
At all times.ACTION: With radioactive liquid waste being discharged without treatment and in excess of the above limits and any portion of the Liquid Radwaste Treatment System which could reduce the radioactive liquid waste discharged not in operation, prepare and submit to the Commission within 30 days, pursuant to Specification 6.8.2, a Special Report that includes the following information:
- a. Explanation of why liquid radwaste was being discharged without treatment, identification of any inoperable equipment or subsystems, and the reason for the inoperability, b. Action(s) taken to restore the inoperable equipment to OPERABLE status, and c. Summary description of action(s) taken to prevent a recurrence.
SURVEILLANCE REQUIREMENTS S.6.3.1 Doses due to liquid releases from each unit to UNRESTRICTED AREAS shall be projected at least once per 31 days in accordance with the methodology and parameters in Part B of the ODCM when Liquid Radwaste Treatment Systems are not being fully utilized.S.6.3.2 The installed Liquid Radwaste Treatment System shall be considered OPERABLE by meeting Controls C.6.1.1 and C.6.2.1.A.6-11 ODCM Rev. 33 1 BASES The OPERABILITY of the Liquid Radwaste Treatment System ensures that this system will be available for use whenever liquid effluents require treatment prior to release to the environment.
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.
This specification implements the requirements of 10 CFR 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50, and the design objective given in Section II.D of Appendix I to 10 CFR Part 50. 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 A to 10 CFR Part 50 for liquid effluents.
A.6-12 ODCM Rev. 33 1 7.0 RADIOACTIVE GASEOUS EFFLUENTS 7.1 Dose Rate CONTROLS C.7.1.1 The dose rate due to radioactive materials released in gaseous effluents from the site to areas at and beyond the SITE BOUNDARY (see Technical Specification Figure 5.1-1)shall be limited to the following:
- a. For noble gases: Less than or equal to 500 mrems/yr to the whole body and less than or equal to 3000 mrems/yr to the skin, and b. For Iodine-131, for Iodine-133, for tritium, and for all radionuclides in particulate form with half-lives greater than 8 days: Less than or equal to 1500 mrems/yr to any organ.APPLICABILITY:
At all times.ACTION: With the dose rate(s) exceeding the above limits, decrease the release rate within 15 minutes to within the above limit(s).SURVEILLANCE REQUIREMENTS S.7.1.1 The dose rate due to noble gases in gaseous effluents shall be determined to be within the above limits in accordance with the methodology and parameters in Part B of the ODCM.S.7.1.2 The dose rate due to Iodine-131, Iodine-133, tritium, and all radionuclides in particulate form with half-lives greater than 8 days in gaseous effluents shall be determined to be within the above limits in accordance with the methodology and parameters in the ODCM by obtaining representative samples and performing analyses in accordance with the sampling and analysis program specified in Table A.7.1-1.A.7-1 ODCM Rev. 25 BASES This Control is provided to ensure that the dose at any time at and beyond the SITE BOUNDARY from gaseous effluents from all units on the site will be within the annual dose limits of 10 CFR Part 20 to UNRESTRICTED AREAS. The annual dose limits are the doses associated with the concentrations of 10 CFR Part 20, Appendix B, Table 2, Column 1. These limits provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of a MEMBER OF THE PUBLIC in an UNRESTRICTED AREA, either within or outside the SITE BOUNDARY, to annual average concentrations exceeding the limits specified in Appendix B, Table 2 of 10 CFR Part 20 (10 CFR Part 20.1302[c]).
For MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy of the MEMBER OF THE PUBLIC will usually be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the SITE BOUNDARY.Examples of calculations for such MEMBERS OF THE PUBLIC, with the appropriate occupancy factors, shall be given in the ODCM. The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to a MEMBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal to 500 mrems/year to the whole body or to less than or equal to 3000 mrems/year to the skin. These release rate limits also restrict, at all times, the corresponding thyroid dose rate above background to a child via the inhalation pathway to less than or equal to 1500 mrems/year.

Values determined to be below detectable levels are not used in dose calculations.

The Control implements the guides set forth in Section I.B of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I at the SITE BOUNDARY that the releases of radioactive material in gaseous effluents to UNRESTRICTED AREAS will be kept as low as reasonably achievable.
The Surveillance Requirements implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated.
The dose calculation methodology and parameters established in the ODCM 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 ODCM equations provided for determining the air doses at and beyond the SITE BOUNDARY are based upon the historical average atmospheric conditions.

- a. During any calendar quarter: Less than or equal to 7.5 mrems to any organ, and b. During any calendar year: Less than or equal to 15 mrems to any organ.APPLICABILITY:
At all times.ACTION: With the calculated dose from the release of Iodine- 131, Iodine-133, tritium, and radionuclides in particulate form with half-lives greater than 8 days, in gaseous effluents exceeding any of the above limits, prepare and submit to the Commission within 30 days, pursuant to Technical Specification 6.8.2, a Special Report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions that have been taken to reduce the releases and the proposed corrective actions to be taken to assure that subsequent releases will be in compliance with the above limits.SURVEILLANCE REQUIREMENTS S.7.3.1 Cumulative dose contributions for the current calendar quarter and current calendar year for Iodine- 131, Iodine- 133, tritium, and radionuclides in particulate form with half-lives greater than.8 days shall be determined in accordance with the methodology and parameters in Part B of the ODCM at least once per 31 days.A.7-9 ODCM Rev. 25 BASES This Control is provided to implement the requirements of Sections II.C, IH.A, and IV.A of Appendix I to 10 CFR Part 50. The Controls 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 [V.A of Appendix I to assure that the releases of radioactive materials in gaseous effluents at the SITE BOUNDARY will be kept as low as reasonably achievable.
The ODCM calculation methods specified in the Surveillance Requirements implement the requirements in Section lII.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated.
The ODCM calculational methodology and parameters 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 Iodine-133, tritium, and radionuclides in particulate form with half-lives greater than 8 days are dependent upon the existing radionuclide pathways to man in the areas at and beyond the SITE BOUNDARY.
The pathways that were examined in the development of the calculations were (1) individual inhalation of airborne radionuclides, (2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, (3) deposition of radionuclides onto grassy areas where milk animals and meat-producing animals graze followed by human consumption of that milk and meat, and (4) deposition of radionuclides on the ground followed by subsequent human exposure.A.7-10 ODCM Rev. 25 7.4 Gaseous Radwaste Treatment System CONTROLS C.7.4.1 The VENTILATION EXHAUST TREATMENT SYSTEM and the GASEOUS RADWASTE TREATMENT SYSTEM shall be OPERABLE and appropriate portions of these system shall be used to reduce releases of radioactivity when the projected doses in 31 days due to gaseous effluent releases to areas at and beyond the SITE BOUNDARY (see Technical Specification Figure 5.1-1) would exceed a. 0.2 mrad to air from gamma radiation, or b. 0.4 mrad to air from beta radiation, or c. 0.3 mrem to any organ of a MEMBER OF THE PUBLIC.APPLICABILITY:
At all times.ACTION: With radioactive gaseous waste being discharged without treatment and in excess of the above limits, prepare and submit to the Commission within 30 days, pursuant to Specification 6.8.2, a Special Report that includes the following information:
- a. Identification of any inoperable equipment or subsystems, and the reason for the inoperability, b. Action(s) taken to restore the inoperable equipment to OPERABLE status, and c. Summary description of action(s) taken to prevent a recurrence.
SURVEILLANCE REQUIREMENTS S.7.4.1 Doses due to gaseous releases from each unit to areas at and beyond the SITE BOUNDARY shall be projected at least once per 31 days in accordance with the methodology and parameters in Part B of the ODCM when Gaseous Radwaste Treatment Systems are not being fully utilized.S.7.4.2 The installed VENTILATION EXHAUST TREATMENT SYSTEM and GASEOUS RADWASTE TREATMENT SYSTEM shall be considered OPERABLE by meeting Controls C.7.1.1, and C.7.2.1, or C.7.3.1.A.7-11 ODCM Rev. 25 BASES The OPERABILITY of the GASEOUS RADWASTE TREATMENT SYSTEM and the VENTILATION EXHAUST TREATMENT SYSTEM ensures that the systems will be available for use whenever gaseous effluents require treatment prior to release to the environment.
The requirement that the appropriate portions of these systems be used, when specified, provides reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept as low as is reasonably achievable.
This Control implements the requirements of 10 CFR 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50, and the design objectives given in Section II.D of Appendix I to 10 CFR Part 50. The specified limits governing the use of appropriate portions of the systems were specified as a suitable fraction of the dose design objectives set forth in Sections II.B and II.C of Appendix I to 10 CFR Part 50, for gaseous effluents.
A.7-12 ODCM Rev. 25 8.0 TOTAL DOSE CONTROL C.8.1.1 The annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC due to releases of radioactivity and to radiation from uranium fuel cycle sources shall be limited to less than or equal to 25 mrems to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems.APPLICABILITY:
At all times.ACTION: With the calculated doses from the release of radioactive materials in liquid or gaseous effluents exceeding twice the limits of Controls C.6.2.1 .a, C.6.2.I .b, C.7.2.1 .a, C.7.2.1 .b, C.7.3.1 .a, or C.7.3.1 .b, calculations shall be made including direct radiation contributions from the units and from outside storage tanks to determine whether the above limits of Control C.8. 1.1 have been exceeded.
If such is the case, prepare and submit to the Commission within 30 days, pursuant to Technical Specification 6.8.2, a Special Report that defines the corrective action to be taken to reduce subsequent releases to prevent recurrence of exceeding the above limits and includes the schedule for achieving conformance with the above limits. This Special Report, as defined in 10 CFR 20.2203(a)(4), shall include an analysis that estimates the radiation exposure (dose) to a MEMBER OF THE PUBLIC from uranium fuel cycle sources, including all effluent pathways and direct radiation, for the calendar year that includes the release(s) covered by this report. It shall also describe levels of radiation and concentrations of radioactive material involved, and the cause of the exposure levels or concentrations.
If the estimated dose(s) exceeds the above limits, and if the release condition resulting in violation of 40 CFR Part 190 has not already been corrected, the Special Report shall include a request for a variance in accordance with the provisions of 40 CFR Part 190. Submittal of the report is considered a timely request, and a variance is granted until staff action on the request is complete.SURVEILLANCE REQUIREMENTS S.8.1.1 Cumulative dose contributions from liquid and gaseous effluents shall be determined in accordance with Surveillance Requirement S.6.2.1, S.7.2.1, and S.7.3.1, and in accordance with the methodology and parameters in Part B of the ODCM.S.8.1.2 Cumulative dose contributions from direct radiation from plant facilities, including radwaste storage tanks and Dry Fuel Storage Facility, shall be determined in accordance with the methodology and parameters in Part B of the ODCM. This requirement is applicable only under conditions set forth in ACTION a. of Control C.8.1.1.A.8-1 ODCM Rev. 32 BASES This Control is provided to meet the dose limitations of 40 CFR Part 190 that have been incorporated into 10 CFR Part 20 by 46FR18525.
The specification requires the preparation and submittal of a Special Report whenever the calculated doses due to releases of radioactivity and to radiation from uranium fuel cycle sources exceed 25 mrems to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems. For sites containing up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the individual reactors remain within twice the dose design objectives of Appendix I, and if direct radiation doses from the units (including outside storage tanks, solid radwaste storage and dry fuel storage, etc.) are kept small. The Special Report will describe a course of action that should result in the limitation of the annual dose to a MEMBER OF THE PUBLIC to within 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 are 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 [equivalent to 10 CFR 72.104(a) for Dry Fuel Storage considerations], the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected), in accordance with the provisions of 40 CFR 190.11 and 10 CFR 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 limitation of 10 CFR Part 20, as addressed in Controls C.6. 1.1 and C.7. 1.1. An individual is not considered a MEMBER OF THE PUBLIC during any period in which he/she is engaged in carrying out any operation that is part of the nuclear fuel cycle.A.8-2 ODCM Rev. 32 1 9.0 RADIOLOGICAL ENVIRONMENTAL MONITORING 9.1 Plant Operations Monitoring Program CONTROL C.9.1.1 The Radiological Environmental Monitoring Program (REMP) shall be conducted as specified in Table A.9.1-1.APPLICABILITY:

With the REMP not being conducted as specified in Table A.9.1-1, prepare and submit to the Commission, in the Annual Radiological Environmental Operating Report required by Technical Specification 6.8.1.3 and Part A, Section 10.1 of the ODCM, a description of the reasons for not conducting the program as required and the plans for preventing a recurrence.
- b. With the level of radioactivity as the result of plant effluents in an environmental sampling medium at a specified location exceeding the reporting levels of Table A.9.1-3 when averaged over any calendar quarter, prepare and submit to the Commission within 30 days from receipt of the laboratory analyses, pursuant to Technical Specification 6.8.2, a Special Report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions to be taken to reduce radioactive effluents so that the potential annual dose* to a MEMBER OF THE PUBLIC is less than the calendar year limits of Control C.6.2.1, C.7.2.1, or C.7.3.1. When more than one of the radionuclides in the REMP are detected in the sampling medium, this report shall be submitted if concentration (1) concentration (2)reporting level (1) + reporting level (2) + ...> 1.0 When radionuclides other than those listed in the REMP are detected and are the result of plant effluents, this report shall be submitted if the potential annual dose*to a MEMBER OF THE PUBLIC from all radionuclides is equal to or greater than the calendar year limits of Control C.6.2.1, C.7.2.1, or C.7.3.1. 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 required by Technical Specification 6.8.1.3 and Part A, Section 10.1 of the ODCM.*The methodology and parameters used to estimate the potential annual dose to a MEMBER OF THE PUBLIC shall be indicated in this report.A.9-1 ODCM Rev. 35 ACTION: (Continued)
With milk or fresh leafy vegetable samples unavailable from one or more of the sample locations required by the REMP, identify specific locations for obtaining replacement samples and add them within 30 days to the REMP given in the ODCM. The specific locations from which samples were unavailable may then be deleted from the monitoring program. Pursuant to Technical Specification 6.13, and Part A, Section 10.2, of the ODCM, submit in the next Annual Radioactive Effluent Release Report documentation for a change in the ODCM including a revised figure(s) and table for the ODCM reflecting the new location(s) with supporting information identifying the cause of the unavailability of samples and justifying the selection of the new locations(s) for obtaining samples.SURVEILLANCE REQUIREMENTS S.9.1.1 The radiological environmental monitoring samples shall be collected pursuant to Table A.9.1-1 from the specific locations given in the table and figure(s) in Part B of the ODCM, and shall be analyzed pursuant to the requirements of Table A.9.1-1 and the detection capabilities required by Table A.9.1-2.BASES The REMP required by this Control provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures of MEMBERS OF THE PUBLIC resulting from the plant operation.
This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 50, and thereby supplements the REMP 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 the modeling of the environmental exposure pathways.
Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring, Revision 1, November 1979. The initially specified monitoring program will be effective for at least the first 3 years of commercial operation.
Following this period, program changes may be initiated based on operational experience.

Other peaks that are identifiable, together with those of the above nuclides, shall also be analyzed and reported in the Annual Radiological Environmental Operating Report.b. The LLD is defined, for purposes of these specifications, as the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be detected with 95% probability with only 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 ExVx 2.22 x10 6 x Yxexp(-AAt)
Where: LLD is the "a priori" lower limit of detection as defined above, as picocuries per unit mass or volume;4.66 is a constant derived from the Kalpha and Kbeta values for the 95% confidence level;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 disintegration; V is the sample size in units of mass or volume;2.22 is the number of disintegrations per minute per picocurie; Y is the fractional radiochemical yield, when applicable; 2 is the radioactive decay constant for the particular radionuclide as per second; and A t for environmental samples is the elapsed time between sample collection and time of counting, as seconds.Typical values of E, V, Y, and A t should be used in the calculation.
In calculating the LLD for a radionuclide determined by gamma ray spectrometry, the background shall include the typical contributions of other radionuclides normally present in the samples (e.g., Potassium-40 in milk samples).A.9-8 ODCM Rev. 35 TABLE A.9.1-2 DETECTION CAPABILITIES FOR ENVIRONMENTAL SAMPLE ANALYSIS (Continued)
Table Notations (Continued)
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.
This does not preclude the calculation of an a posteriori LLD for a particular measurement based upon the actual parameters for the sample in question and appropriate decay correction parameters such as decay while sampling and during analysis.Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions.
Occasionally background fluctuations, unavoidable small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable.
In such cases, the contributing factors shall be identified and described in the Annual Radiological Environmental Operating Report per Part A, Section 10.1.c. Parent only.d. The Ba-140 LLD and concentration can be determined by the analysis of its short-lived daughter product La-140 subsequent to an eight-day period following collection.
The calculation shall be predicated on the normal ingrowth equations for a parent-daughter situation and the assumption that any unsupported La-140 in the sample would have decayed to an insignificant amount (at least 3.6% of its original value). The ingrowth equations will assume that the supported La-140 activity at the time of collection is zero.e. Broad leaf vegetation only.f. If the measured concentration minus the three standard deviation uncertainty is found to exceed the specified LLD, the sample does not have to be analyzed to meet the specified LLD.g.

APPLICABILITY:
At all times.ACTION a. With a Land Use Census identifying a location(s) that yields a calculated dose or dose commitment greater than the values currently being calculated in Surveillance S.7.3.1 pursuant to Technical Specification 6.8.1.4 and Part A, Section 10.2, of the ODCM, identify the new location(s) in the next Annual Radioactive Effluent Release Report.b. With a Land Use Census identifying a location(s) that yields a calculated dose or dose commitment (via the same exposure pathway) 20% greater than at a location from which samples are currently being obtained in accordance with Control C.9.1.1, add the new location(s) within 30 days to the REMP given in the ODCM, if permission from the owner to collect samples can be obtained and sufficient sample volume is available.
The sampling location(s), excluding the Control station location, having the lowest calculated dose or dose commitment(s), 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.
Pursuant to Technical Specification 6.13 and Part A, Section 10.2 of the ODCM, submit in the next Annual Radioactive Effluent Release Report documentation for a change in the ODCM including a revised figure(s) and table(s) for the ODCM reflecting the new location(s) with information supporting the change in sampling locations.
SURVEILLANCE REQUIREMENTS S.9.2.1 The Land Use Census shall be conducted during the growing season at least once per 12 months using a method such as by a door-to-door survey, aerial survey, or by consulting local agriculture authorities, as described in the ODCM. The results of the Land Use Census shall be included in the Annual Radiological Environmental Operating Report pursuant to Part A, Section 10.1 of the ODCM.**Broad leaf vegetation sampling of at least three different kinds of vegetation may be performed at the SITE BOUNDARY in each of two different direction sectors with the highest predicted relative deposition values (D/Qs) in lieu of the garden census. Specifications for broad leaf vegetation sampling in the REMP shall be followed, including analysis of control samples.A.9-11I ODCM Rev. 35 BASES This specification is provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the REMP given in the ODCM are made if required by the results of this census. Information from methods such as the door-to-door survey, from aerial survey, of from consulting with local agricultural authorities shall be used. 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 50 m 2 provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored, since a garden of this size is the minimum required to produce the quantity (26 kg/year) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were made: (1) 20% of the garden was used for growing broad-leaf vegetation (i.e., similar to lettuce and cabbage), and (2) there was a vegetation yield of 2 kg/m 2.A.9-12 ODCM Rev. 35 9.3 Interlaboratory Comparison Program CONTROL C.9.3.1 In accordance with Technical Specification 6.7.6h.3, analyses shall be performed on all radioactive materials supplied as part of an Interlaboratory Comparison Program, that has been approved by the Commission, that correspond to samples required by REMP.APPLICABILITY:
At all times.ACTION: 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 pursuant to Part A, Section 10.1 of the ODCM.SURVEILLANCE REQUIREMENTS S.9.3.1 The Interlaboratory Comparison Program shall be identified in Part B of the ODCM.A summary of the results obtained as part of the above required Interlaboratory Comparison Program shall be included in the Annual Radiological Environmental Operating Report pursuant to Part A, Section 10.1 of the ODCM.BASES The requirement for participation in an approved 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 the Quality Assurance Program for environmental monitoring in order to demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to 10 CFR Part 50.A.9-13 ODCM Rev. 35 9.4 Dry Fuel Storage Facility Monitoring Program CONTROL C.9.4.1 The Dry Fuel Storage Facility radiological environmental monitoring program shall be conducted as specified in Table A.9.4-1 APPLICABILITY:
At all times.ACTION: With the Dry Fuel Storage Facility radiological environmental measurements not being conducted as specified in Table A.9.4-1, prepare and submit to the Commission, in the Annual Radiological Environmental Operating Report required by Technical Specification 6.8.1.3 and Part A, Section 10.1 of the ODCM, a description of the reasons for not conducting the program as required and the plans for preventing a recurrence.
SURVEILLANCE REQUIREMENTS S.9.4.1 The Dry Fuel Storage Facility radiological environmental measurements shall be performed pursuant to Table A.9.4-1 from the specific locations given in the table(s) and figure(s) in Part B of the ODCM, and shall be analyzed pursuant to the requirements of Table A.9.4-1.BASES The Dry Fuel Storage radiological environmental monitoring program required by this Control provides representative measurements of direct (including scattered) radiation exposure at those locations that have the highest potential for dose to MEMBERS OF THE PUBLIC resulting from dry fuel storage operations.
The design of the storage facility is such that there are no liquid or gaseous effluents released to the environment from DFS and, therefore, no associated exposure pathways for liquids and gases requiring the collection and analysis of such sample media. As a result, only direct (including scattered) radiation from the DFS modules need to be monitored for integrated exposures in areas where doses to MEMBERS OF THE PUBLIC need to be limited.This measurement program provides information to support the determination of compliance with the dose criteria of 10 CFR 72.104(a), 40 CFR 190, and 10 CFR 20.1301(a)(1) for that portion of the total annual dose contributed by DFS.A.9-14 ODCM Rev. 35 TABLE A.9.4-1 DRY FUEL STORAGE FACILITY RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Exposure Pathway Number of Locations Collection Frequency Type and Frequency of Analysis DIRECT RADIATION b 14 routine monitoring stations with two or Quarterly.

1.0 INTRODUCTION
The Offsite Dose Calculation Manual (ODCM) contains details to implement Radioactive Effluent Controls and Environmental Monitoring Program as required by Technical Specifications 6.7.6g and 6.7.6h.Part B of the ODCM provides formal and approved methods for the calculation of off-site concentration, off-site doses and effluent monitor setpoints, and indicates the locations of environmental monitoring stations in order to comply with the Seabrook Station Radioactive Effluent Controls Program (RECP), and Radiological Environmental Monitoring Program (REMP) detailed in Part A of the manual. The ODCM forms the basis for station procedures which document the off-site doses due to station operation which are used to show compliance with the numerical guides for design objectives of Section II of Appendix I to 1OCFR Part 50.The methods contained herein follow accepted NRC guidance, unless otherwise noted in the text.The references to 10 CFR Part 20 in Part B of the ODCM refer to revisions of 10 CFR Part 20 published prior to 1 January 1993. The decision to continue the use of the "old" version of 10 CFR Part 20 is based on an NRC letter dated June 30, 1993, from Thomas E. Murley to Thomas E. Tipton. For the convenience of the plant staff a copy of 10 CFR Part 20 (Rev. 1, January 1992) has been included in Appendix B.1.1 Responsibilities for Part B All changes to the ODCM shall be reviewed by the Station Operation Review Committee (SORC), approved by the Station Director, and documented in accordance with Technical Specification 6.13. The change process is controlled by the Applicability Determination Process as controlled by the 10 CFR 50.59 Resource Manual (5059RM).
Changes made to Part B shall be submitted to the Commission for their information in the Annual Radioactive Effluent Release Report for the period in which the change(s) was made effective.
It shall be the responsibility of the Station Director to ensure that the ODCM is used in the performance of surveillance requirements and administrative controls in accordance with Technical Specifications 6.7.6g and 6.7.6h, and Effluent Control Program and Radiological Environmental Monitoring Program detailed in Part A of the manual.In addition to off-site dose calculations for the demonstration of compliance with Technical Specification dose limits at and beyond the site boundary, 10 CFR 20.1302 requires that compliance with the dose limits for individual members of the public (100 mrem/yr total effective dose equivalent) be demonstrated in controlled areas on-site. Demonstration of compliance with the dose limits to members of the public in controlled areas is implemented per Health Physics Department Procedures, and is outside the scope of the ODCM. However, calculations performed in accordance with the ODCM can be used as one indicator of the need to perform an assessment of exposure to members of the public within the site boundary.
Since external direct exposure pathways are already subject to routine exposure rate surveys and measurements, only the inhalation pathway need be assessed.
The accumulated critical organ dose at the site boundary, as calculated per ODCM Part B Sections 3.9 and 3.11, can be used as an indicator of when additional assessments of on-site exposure to members of the public is advisable (see Section 3.11.2). Off-site critical organ doses from station effluents should not, however, be the only indicator of potential on-site doses.B.1-1 ODCM Rev. 33 1 1.2 Summary of Methods, Dose Factors, Limits, Constants, Variables and Definitions This section summarizes the Method I dose equations which are used as the primary means of demonstrating compliance with RECP. The concentration and setpoint methods are identified in Table B.1-2 through Table B.1-7. Appendix C provides documentation for an alternate computerized option, designated as Method IA in the ODCM, for calculating doses necessary to demonstrate compliance with RECP. The Effluent Management System (EMS) software package used for this purpose is provided by Canberra Industries, Inc. Where more refined dose calculations are needed, the use of Method H dose determinations are described in Sections 3.2 through 3.9 and 3.11. The dose factors used in the equations are in Tables B.I-10 through B. 1-14 and the Regulatory Limits are summarized in Table B. 1-l.The variables and special definitions used in this ODCM, Part B, are in Tables B. 1-8 and B. 1-9.B. 1-2 ODCM Rev. 33 I TABLE B. 1 -1

Dose -As used in Regulatory Guide 1.109, the term "dose," when applied to individuals, is used instead of the more precise term "dose equivalent," as defined by the International Commission on Radiological Units and Measurements (ICRU). When applied to the evaluation of internal deposition or radioactivity, the term "dose," as used here, includes the prospective dose component arising from retention in the body beyond the period of environmental exposure, i.e., the dose commitment.
The dose commitment is evaluated over a period of 50 years. The dose is measured in mrem to tissue or mrad to air.Dose Rate -The rate for a specific averaging time (i.e., exposure period) of dose accumulation.
Liquid Radwaste Treatment System -The components or subsystems which comprise the available treatment system as shown in Figure B.6-1.B. 1-22 ODCM Rev. 33 TABLE B.1-10 DOSE FACTORS SPECIFIC FOR SEABROOK STATION FOR NOBLE GAS RELEASES Radio-nuclide Gamma Total Body Dose Factor 3 DFBi (mrem- m3 pCi- yr Beta Skin Dose Factor 3 mrem- m pCi- yr Combined Skin Dose Factor for Elevated Release Points I mrem- sec DFi(e) ( -)p.

demonstrate compliance with ODCM Part A Control C.6. 1.1, which limits the total fraction of ECL in liquid pathways, other than noble gases FENG (denoted here as F ) at the point of discharge from the station to the environment (see Figure B.6-1).EllNG F is limited to less than or equal to ten, i.e., F'q < 10.The total concentration of all dissolved and entrained noble gases at the point of discharge from the multiport diffuser from all station sources combined, denoted CNG , is limited to 2E-04 gCi/ml, i.e., C 1 NG < 2E-04 piCi/ml.Appendix C, Attachments 3 and 4, provide the option and bases for the use of the EMS determination of liquid concentration limits for plant discharges to the environment.
2.1 Method to Determine F 1 ENG AND C 1 NG First, determine the total fraction of ECL (excluding noble gases), at the point of discharge from the station from all significant liquid sources denoted F IEN'; and then separately determine the total concentration at the point of discharge of all dissolved and entrained noble gases from all NG station sources, denoted CG , as follows: F ENG E Y _ Cpi 10 (2-1)1 P i ECL.Ci/ml)/.zcil/ml

See Appendix B for a list of ECL values.C 1 NG Total concentration at point of discharge of alldissolved and entrained noble gases in liquids from all station sources (g.Ci/ml)CING Concentration at point of discharge of dissolved and entrained noble gas "i" in liquids from all station sources (piCi/ml)2.2 Method to Determine Radionuclide Concentration for Each Liquid Effluent Source 2.2.1 Waste Test Tanks Cpi is determined for each radionuclide detected from the activity in a representative grab sample of any of the waste test tanks and the predicted flow at the point of discharge.
The batch releases are normally made from two 25,000-gallon capacity waste test tanks.These tanks normally hold liquid waste which may have been processed through the installed vendor equipment.
The waste test tanks can also contain other waste such as liquid taken directly from the floor drain/chemical drain treatment tanks when that liquid does not require processing in the evaporator, from the installed vendor resin skid, distillate from the boron recovery evaporator when the BRS evaporator is substituting for the waste evaporator, or waste distillate from the Steam Generator Blowdown System when that system must discharge liquid off site.If testing indicates that purification of the waste test tank contents is required prior to release, the liquid can be circulated through the waste demineralizer and filter.The contents of the waste test tank may be reused in the Nuclear System if the sample test meets the purity requirements.
Prior to discharge, each waste test tank is analyzed for principal gamma emitters in accordance with the liquid sample and analysis program outlined in Part A to the ODCM.B.2-2 ODCM Rev. 32 I 2.2.2 Turbine Building Sump The Turbine Building sump collects leakage from the Turbine Building floor drains and discharges the liquid unprocessed to the circulating water system.Sampling of this potential source is normally done onceper week for determining the radioactivity released to the environment (see Table A.6.1-1).2.2.3 Steam Generator Blowdown Flash Tank The primary method to process radioactive secondary liquid from the steam generators is to direct steam blowdown flash tank bottoms cooler discharge to the floor drain tanks. If no secondary pressure is available, the steam blowdown and wet lay-ups pumps can be used. From the floor drain tanks, processing through the installed vendor resin skid (WL-SKD-135) to the waste test tanks is the preferred method. Other methods may be used as defined below.The steam generator blowdown evaporators may process the liquid from the steam generator blowdown flash tank when there is primary to secondary leakage. Distillate from the evaporators can be sent to the waste test tanks or recycled to the condensate system. When there is no primary to secondary leakage, flash tank liquid is processed through the steam generator blowdown demineralizers and returned to the secondary side.Steam generator blowdown is only subject to sampling and analysis when all or part of the blowdown liquid is being discharged to the environment instead of the normal recycling process (see Table A.6.1-1).2.2.4 Primary Component Cooling Water (PCCW) System The PCCW System is used to cool selected primary components.
The system is normally sampled weekly to determine if there is any radwaste in-leakage.
If leakage has been determined, the Service Water System is sampled to determine if any release to the environment has occurred.2.2.5 Water Treatment System (Condensate Polishing System)The addition to the plant design of a Condensate Polishing System (CPS) for secondary side water treatment creates the potential for radiological contaminated effluents to be discharge from the Mixed Bed or Cation Demineralizers (during Megarinse) and from the Neutralization Tank (1-WT-TK-32) and the Low Conductivity Tank (1-CPS-TK-274) to the Circulating Water System via the Water Treatment System Piping following regeneration of the resin beds.Prior to discharge, each tank or vessel to be processed is sampled and analyzed for principal gamma emitters in accordance with the Liquid Sample and Analysis Program outlined in Part A to the ODCM.B.2-3 ODCM Rev. 32 I 3.0 OFF-SITE DOSE CALCULATION METHODS Chapter 3 provides the basis for station procedures required to meet the Radiological Effluent Control Program (RECP) dose and dose rate requirements contained in ODCM Part A Controls.A simple, conservative method (called Method I) is listed in Tables B. 1-2 to B. 1-7 for each of the requirements of the RECP. Each of the Method I equations is presented in Part B, Sections 3.2 through 3.9. As an alternate to Method I, the EMS computer program documented in Appendix C can be used to determine regulatory compliance for effluent doses and dose rates.The use of the EMS software is designated as Method IA in Chapter 3. In addition, those sections include more sophisticated methods (called Method II) for use when more refined results are needed. This chapter provides the methods, data, and reference material with which the operator can calculate the needed doses, dose rates and setpoints.
For the requirements to demonstrate compliance with Part A off-site dose limits, the contribution from all measured ground level releases must be added to the calculated contribution from the vent stack to determine the Station's total radiological impact. The bases for the dose and dose rate equations are given in Chapter 7.0. Method IA bases and software verification documentation are contained in Appendix C.The Annual Radioactive Effluent Release Report, to be filed after January 1 each year per Technical Specification 6.8.1.4, and Part A, Section 10.2, requires that meteorological conditions concurrent with the time of release of radioactive materials in gaseous effluents, as determined by sampling frequency and measurement, be used for determining the gaseous pathway doses.For continuous release sources (i.e., plant vent, condenser air removal exhaust, and gland steam packing exhauster), concurrent quarterly average meteorology will be used in the dose calculations along with the quarterly total radioactivity released.
For batch releases or identifiable operational activities (i.e., containment purge or venting to atmosphere of the Waste Gas System), concurrent meteorology during the period of release will be used to determine dose if the total noble gas or iodine and particulates released in the batch exceeds five percent of the total quarterly radioactivity released from the unit; otherwise quarterly average meteorology will be applied. Quarterly average meteorology will also be applied to batch releases if the hourly met data for the period of batch release is unavailable.
Annual dose assessment reports prepared in accordance with the requirements of the ODCM will include a statement indicating that the appropriate portions of Regulatory Guide 1.109 (as identified in the individual subsections of the ODCM for each class of effluent exposure) have been used to determine dose impact from station releases.
Any deviation from the methodology, assumptions, or parameters given in Regulatory Guide 1.109, and not already identified in the bases of the ODCM, will be explicitly described in the effluent report, along with the bases for the deviation.
B.3-1 ODCM Rev. 32 1 3.1 Introductory Concepts In Part A Controls, the RECP limits for dose or dose rate are stated. The term "dose" for ingested or inhaled radioactivity means the dose commitment, measured in mrem, which results from the exposure to radioactive materials that, because of uptake and deposition in the body, will continue to expose the body to radiation for some period of time after the source of radioactivity is stopped. The time frame over which the dose commitment is evaluated is 50 years. The phrases "annual dose" or "dose in one year" then refers to the 50-year dose commitment resulting from exposure to one year's worth of releases. "Dose in a quarter" similarly means the 50-year dose commitment resulting from exposure to one quarter's releases.The term "dose," with respect to external exposures, such as to noble gas clouds, refers only to the doses received during the actual time period of exposure to the radioactivity released from the plant. Once the source of the radioactivity is removed, there is no longer any additional accumulation to the dose commitment."Dose rate" is the total dose or dose commitment divided by exposure period. For example, an individual who is exposed via the ingestion of milk for one year to radioactivity from plant gaseous effluents and receives a 50-year dose commitment of 10 mrem is said to have been exposed to a dose rate of 10 mrem/year, even though the actual dose received in the year of exposure may be less than 10 mrem.In addition to limits on dose commitment, gaseous effluents from the station are also controlled so that the maximum or peak dose rates at the site boundary at any time are limited to the equivalent annual dose limits of 10 CFR Part 20 to unrestricted areas (if it were assumed that the peak dose rates continued for one year). These dose rate limits provide reasonable assurance that members of the public, either inside or outside the site boundary, will not be exposed to annual averaged concentrations exceeding the limits specified in Appendix B, Table 2 of 10 CFR Part 20. See Appendix B for a listing of these concentration limits.The quantities AD and f) are introduced to provide calculable quantities, related to off-site doses or dose rates that demonstrate compliance with the RETS.Delta D, denoted AD, is the quantity calculated by the Part B, Chapter 3, Method I dose equations.
It represents the conservative increment in dose. The AD calculated by Method I equations is not necessarily the actual dose received by a real individual, but usually provides an upper bound for a given release because of the conservative margin built into the dose factors and the selection and definition of critical receptors.
The radionuclide specific dose factors in each Method I dose equation represent the greatest dose to any organ of any age group. (Organ dose is a function of age because organ mass and intake are functions of age.) The critical receptor assumed by "Method I" equations is then generally a hypothetical individual whose behavior -in terms of location and intake -results in a dose which is higher than any real individual is likely to receive. Method IA dose calculations using the EMS software evaluate each age group and organ combination to determine the maximum organ dose for each mix of radionuclides specified in a release period. Method II also allows for a more exact dose calculation for each individual if necessary.
B.3-2 ODCM Rev. 32 1 D dot, denoted D, is the quantity calculated in the Part B, Chapter 3 dose rate equations.
It is calculated using the station's effluent monitoring system reading and an annual or long-term average atmospheric dispersion factor. D) predicts the maximum off-site annual dose if the peak observed radioactivity release rate from the plant stack continued for one entire year. Since peak release rates, or resulting dose rates, are usually of short time duration on the order of an hour or less, this approach then provides assurance that 10 CFR 20.106 limits will be met.Each of the methods to calculate dose or dose rate is presented in the following subsections.
Each dose type has two levels of complexity.
Method I is the simplest and contains many conservative factors. As an alternate to Method I the EMS computer program documented in Appendix C can be used to determine regulatory compliance for effluent doses and dose rates.The use of the EMS system is designated as Method IA in Chapter 3 of Part B.Method H is a more realistic analysis which makes use of the models in Regulatory Guide 1.109 (Revision 1), as noted in each subsection of Part B, Chapter 3 for the various exposure types. A detailed description of the methodology, assumptions, and input parameters to the dose models that are applied in each Method H calculation, if not already explicitly described in the ODCM, shall be documented and provided when this option is used for NRC reporting and ODCM, Part A RECP dose compliance.
B .3 -3 ODCM Rev. 32 I 3.2 Method to Calculate the Total Body Dose from Liquid Releases Part A Control C.6.2.1 limits the total body dose commitment to a member of the public from radioactive material in liquid effluents to 1.5 mrem per quarter and 3 mrem per year per unit.Part A Control C.6.3.1 requires liquid radwaste treatment when the total body dose estimate exceeds 0.06 mrem in any 31-day period. Part A Control C.8.1.1 limits the total body dose commitment to any real member of the public from all station sources (including liquids) to 25 mrem in a year.Use Method I or Method IA first to calculate the maximum total body dose from a liquid release from the station as it is simpler to execute and more conservative than Method 1I.Use Method II if a more refined calculation of total body dose is needed, i.e., Method I or Method IA indicates the dose might be greater than Part A Control limits.To evaluate the total body dose, use Equation 3-1 to estimate the dose from the planned release and add this to the total body dose accumulated from prior releases during the month. See Part B, Section 7.1.1 for basis.3.2.1 Method I The total body dose from a liquid release is: Dtb = k Qi DFLitb (3-1)(mrem) = () (Ci)mrem where DFLitb Site-specific total body dose factor (mrem/ýCi) for a liquid release. It is the highest of the four age groups. See Table B.1-11.Qi Total activity (giCi) released for radionuclide "i". (For strontiums, use the most recent measurement available.)
k = 918/Fd; where Fd is the average (typically monthly average) dilution flow of the Circulating Water System at the point of discharge from the multiport diffuser (in ft 3/sec). For normal operations with a cooling water flow of 918 ft 3/sec, k is equal to 1. During periods when no or low flow is recorded from the Discharge Transition Structure (DTS), a minimum dilution flow of 23 ft 3/sec (10,500 gpm for one service water pump) can be used since this would be the minimum flow available when discharges to the tunnel are reestablished.
Alternately, the monthly average discharge flow for the period in which the release occurs can be used when this value is available.
13.3 -4 ODCM Rev. 32 1 3.2 Method to Calculate the Total Body Dose from Liquid Releases 3.2.1 Method I (Continued)
Equation 3-1 can be applied under the following conditions (otherwise, justify Method I or consider Method II): 1. Liquid releases via the multiport diffuser to unrestricted areas (at the edge of the initial mixing or prompt dilution zone that corresponds to a factor of 10 dilution), and 2. Any continuous or batch release over any time period up to 1 year. For annual dose estimates, the annual average discharge flow from the DTS should be used as the dilution flow estimate.Method IA is implemented by the EMS software as described in Appendix C. Liquid release models are detailed in sections 2.1 -2.6 of the EMS Technical Reference Manual (Attachment 4 of Appendix C).3.2.2 Method H Method II consists of the models, input data and assumptions (bioaccumulation factors, shore-width factor, dose conversion factors, and transport and buildup times) in Regulatory Guide 1.109, Rev. I (Reference A), except where site-specific data or assumptions have been identified in the ODCM. The general equations (A-3 and A-7) taken from Regulatory Guide 1.109, and used in the derivation of the simplified Method I approach as described in the Bases section, are also applied to Method II assessments, except that doses calculated to the whole body from radioactive effluents are evaluated for each of the four age groups to determine the maximum whole body dose of an age-dependent individual via all existing exposure pathways.
Table B.7-1 lists the usage factors of Method H calculations.
As noted in Section B.7.1, the mixing ratio associated with the edge of the 1IF surface isotherm above the multiport diffuser may be used in Method H calculations for the shoreline exposure pathway (Mp = 0.025). Aquatic food ingestion pathways shall limit credit taken for mixing zone dilution to the same value assumed in Method I (Mp = 0.10).B.3-5 ODCM Rev. 32 1 3.3 Method to Calculate Maximum Organ Dose from Liquid Releases Part A Control C.6.2.1 limits the maximum organ dose commitment to a Member of the Public from radioactive material in liquid effluents to 5 mrem per quarter and 10 mrem per year per unit.Part A Control C.6.3.1 requires liquid radwaste treatment when the maximum organ dose projected exceeds 0.2 mrem in any 31 days (see Part B, Subsection 3.11 for dose projections).
Part A Control C.8.1.1 limits the maximum organ dose commitment to any real member of the public from all station sources (including liquids) to 25 mrem in a year except for the thyroid, which is limited to 75 mrem in a year.Use Method I or Method IA first to calculate the maximum organ dose from a liquid release to unrestricted areas (see Figure B.6-1) as it is simpler to execute and more conservative than Method II.Use Method II if a more refined calculation of organ dose is needed, i.e., Method I or Method IA indicates the dose may be greater than the limit.Use Equation 3-2 to estimate the maximum organ dose from individual or combined liquid releases.
See Part B, Section 7.1.2 for basis.3.3.1 Method I The maximum organ dose from a liquid release is: Dmo = k Qi DFLimo (3-2)(mrem) = () (Ci)mrem where DFLimo Site-specific maximum organ dose factor (mrem/gCi) for a liquid release. It is the highest of the four age groups. See Table B.1-11.Q Total activity (gtCi) released for radionuclide "i". (For composited analyses of strontiums, use the most recent measurement available.)
k 918/Fd; where Fd is the average (typically monthly average) dilution flow of the Circulating Water System at the point of discharge from the multiport diffuser (in ft 3/sec). For normal operations with a cooling water flow of 918 ft 3/sec, k is equal to 1. During periods when no or low flow is recorded from the Discharge Transition Structure (DTS), a minimum dilution flow of 23 ft 3/sec (10,500 gpm for one service water pump) can be used since this would be the minimum flow available when discharges to the tunnel are reestablished.
Alternately, the monthly average discharge flow for the period in which the release occurs can be used when this value is available.
B .3 -6 ODCM Rev. 32 1 3.3 Method to Calculate Maximum Organ Dose from Liquid Releases 3.3.1 Method I (Continued)
Equation 3-2 can be applied under the following conditions (otherwise, justify Method I or consider Method II): 1. Liquid releases via the multiport diffuser to unrestricted areas (at the edge of the initial mixing or prompt dilution zone that corresponds to a factor of 10 dilution), and 2. Any continuous or batch release over any time period up to 1 year. For annual dose estimates, the annual average discharge flow from the DTS should be used as the dilution flow estimate.Method IA is implemented by the EMS software as described in Appendix C. Liquid release models are detailed in sections 2.1 -2.6 of the EMS Technical Reference Manual (Attachment 4 of Appendix C).3.3.2 Method II Method II consists of the models, input data and assumptions (bioaccumulation factors, shore-width factor, dose conversion factors, and transport and buildup times) in Regulatory Guide 1.109, Rev. 1 (Reference A), except where site-specific data or assumptions have been identified in the ODCM. The general equations (A-3 and A-7) taken from Regulatory Guide 1.109, and used in the derivation of the simplified Method 1 approach as described in the Bases section, are also applied to Method II assessments, except that doses calculated to critical organs from radioactive effluents are evaluated for each of the four age groups to determine the maximum critical organ of an age-dependent individual via all existing exposure pathways.Table B.7-1 lists the usage factors for Method II calculations.
As noted in Section B.7.1, the mixing ratio associated with the edge of the IF surface isotherm above the multiport diffuser may be used in Method II calculations for the shoreline exposure pathway (Mp = 0.025).Aquatic food ingestion pathways shall limit credit taken for mixing zone dilution to the same value assumed in Method I (Mp = 0.10).B.3-7 ODCM Rev. 32 1 3.4 Method to Calculate the Total Body Dose Rate from Noble Gases Part A Control C.7. 1.1 limits the dose rate at any time to the total body from noble gases at any location at or beyond the site boundary to 500 mrem/year.
The Part A Control indirectly limits peak release rates by limiting the dose rate that is predicted from continued release at the peak rate. By limiting IDb to a rate equivalent to no more than 500 mrem/year, we assure that the total body dose accrued in any one year by any member of the general public is less than 500 mrem.Use Method I or Method IA first to calculate the Total Body Dose Rate from the peak release rate via the station vents or ground level effluent release points. Method I applies at all release rates.Use Method H if a more refined calculation of 15,b is desired by the station (i.e., use of actual release point parameters with annual or actual meteorology to obtain release-specific X/Qs) or if Method I or Method IA predicts a dose rate greater than the Part A Control limit to determine if it had actually been exceeded during a short time interval.
See Part B, Section 7.2.1 for basis.Compliance with the dose rate limits for noble gases are continuously demonstrated when effluent release rates are below the plant vent noble gas activity monitor alarm setpoint by virtue of the fact that the alarm setpoint is based on a value which corresponds to the off-site dose rate limit, or a value below it. Determinations of dose rate for compliance with Part A Control are performed when the effluent monitor alarm setpoint is exceeded, or as required by the Action Statement (Part A Control C.5.2, Table A.5.2-1) when the monitor is inoperable.
3.4.1 Method I The Total Body Dose Rate to an off-site receptor due to noble gases in effluents released via the plant vent can be determined as follows: 6D = 0.85
- i Q DFBi (3-3a)mrem (pCi-sec) ( ,uCi) rmrem -m3 yr -UCi-m3 sec pCi-yr )where Db(e) = The off-site total body dose rate (mrem/yr) due to noble gases in elevated effluent releases, Q = the release rate at the station vents ([tCi/sec), for each noble gas radionuclide, "i", shown in Table B.I-10, and DFBi = total body gamma dose factor (see Table B.I-10).The Total Body Dose Rate (to an off-site receptor) due to noble gas in ground level effluent releases can be determined as follows: B.3-8 ODCM Rev. 32 1 3.4 Method to Calculate the Total Body Dose Rate from Noble Gases 3.4.1 Method I (Continued)
Itb(g) 3.4 *X(0i*DFBi) mre _pCi-sec yr PCI -rnec (3-3b)r mrem -m3ý pCi -yr )where Dtb(g)= The total off-site body dose rate (mrem/yr) due to noble gases in ground level equivalent effluent releases, and and DFBi are as defined for Equation 3-3a.For the special on-site receptor locations, the Science & Nature Center and the "Rocks," the total body dose rates due to noble gases in effluent discharges can be determined as follows: For the Science & Nature Center, elevated effluent release: DtbE(e)= 0.00 15
- I (i
- DFBi)(3-3c)For the Science & Nature Center, ground level effluent release: DtbE(g)= 0.0074
- Y (i
- DFBi)(3-3d)For the "Rocks," elevated effluent release: DtbR(e) = 0.038
- Oj (i
- DFBi)For the "Rocks," ground level effluent release: DtbR(g) =0.2 * (Qi
- DFRl)(3-3e)(3-3f where DtbE(e), DtbE(g), DtbR(e), and DtbR(g)= The total body dose rate (mrem/yr) at the Science &Nature Center and the "Rocks," respectively, due to noble gases in gaseous discharges from elevated (e)and ground level (g) release points, andand DFBi are as defined previously.
13.3 -9 ODCM Rev. 32 1 Equations 3-3a through 3-3f can be applied under the following conditions (otherwise, justify Method I or consider Method II): 1. Normal operations (nonemergency event), and 2. Noble gas releases via any station vent to the atmosphere.
Method IA is implemented by the EMS software as described in Appendix C. Gaseous release models are detailed in Section 6.7.3 of the EMS Software Requirements Specification (Attachment 3 of Appendix C).3.4.2 Method II Method II consists of the model and input data (whole body dose factors) in Regulatory Guide 1.109, Rev. 1 (Reference A), except where site-specific data or assumptions have been identified in the ODCM. The general equation (B-8) taken from Regulatory Guide 1.109, and used in the derivation of the simplified Method I approach as described in the Bases section, is also applied to a Method II assessment.
No credit for a shielding factor (SF) associated with residential structures is assumed. Concurrent meteorology with the release period may be utilized for the gamma atmospheric dispersion factor identified in ODCM Equation 7-3 (Part B, Section 7.2.1), and determined as indicated in Part B, Section 7.3.2' for the release point (either ground level or vent stack) from which recorded effluents have been discharged.
B.3-10 ODCM Rev. 32 3.5 METHOD TO CALCULATE THE SKIN DOSE RATE FROM NOBLE GASES Part A Control C.7.1.1 limits the dose rate at any time to the skin from noble gases at any location at or beyond the site boundary to 3,000 mrem/year.
The Part A Control indirectly limits peak release rates by limiting the dose rate that is predicted from continued release at the peak rate. By limiting Dskin to a rate equivalent to no more than 3,000 mrem/year, we assure that the skin dose accrued in any one year by any member of the general public is less than 3,000 mrem.Since it can be expected that the peak release rate on which Oskin is derived would not be exceeded without corrective action being taken to lower it, the resultant average release rate over the year is expected to be considerably less than the peak release rate.Use Method I or Method IA first to calculate the Skin Dose Rate from peak release rate via station vents. Method I applies at all release rates.Use Method II if a more refined calculation of I)skin is desired by the station (i.e., use of actual release point parameters with annual or actual meteorology to obtain release-specific X/Qs) or if Method I or Method IA predicts a dose rate greater than the Part A Control limit to determine if it had actually been exceeded during a short time interval.
See Part B, Section 7.22 for basis.Compliance with the dose rate limits for noble gases are continuously demonstrated when effluent release rates are below the plant vent noble gas activity monitor alarm setpoint by virtue of the fact that the alarm setpoint is based on a value which corresponds to the off-site dose rate limit, or a value below it. Determinations of dose rate for compliance with Part A Controls are performed when the effluent monitor alarm setpoint is exceeded.3.5.1 Method I For an off-site receptor and elevated effluent release, the Skin Dose Rate due to noble gases is: Oskin(e) Qi
- DFi(e)) (3-4a)mremn _ p/Ci) (mrem-sec) yr s u(i.iCi m -cyr where Dskin(e) = the off-site skin dose rate (mrem/yr) due to noble gases in an effluent discharge from an elevated release point, Q. = as defined previously, and DFl'e) the combined skin dose factor for elevated discharges (see Table B.1-l0).B.3-11 ODCM Rev. 32 1 For an off-site receptor and ground level release, the skin dose rate due to noble gases is: Dskin(g) X(.i
- DFi(g)) (3-4b)where D skin(g) The off-site skin dose rate (mrem/yr) due to noble gases in an effluent discharge from a ground level release point, Q= as defined previously, and DFi'(j) = The combined skin dose factor for ground level discharges (see Table B.1-10).For an on-site receptor at the Science & Nature Center and elevated release conditions, the skin dose rate due to noble gases is: DskinE(e)
=0.0014* Z (Qi
- DFiE(e)) (3-4c)where DbskinE(e)
= The skin dose rate (mrem/yr) at the Science & Nature Center due to noble gases in an elevated release, Qi = as defined previously, and DFi'(e) = the combined skin dose factor for elevated discharges (see Table B.1-13).For an on-site receptor at the Science & Nature Center and ground level release conditions, the skin dose rate due to noble gases is: DskinE(g)

B.3-14 ODCM Rev. 32 1 3.6 Method to Calculate the Critical Organ Dose Rate from lodines, Tritium and Particulates with TI2 Greater Than 8 Days Part A Control C.7.1.1 limits the dose rate at any time to any organ from 1311, 1331, 3 H and radionuclides in particulate form with half lives greater than 8 days to 1500 mrem/year to any organ. The Part A Control indirectly limits peak release rates by limiting the dose rate that is predicted from continued release at the peak rate. By limiting Dco to a rate equivalent to no more than 1500 mrem/year, we assure that the critical organ dose accrued in any one year by any member of the general public is less than 1500 mrem.Use Method I or Method IA first to calculate the Critical Organ Dose Rate from the peak release rate via the station vents. Method I applies at all release rates.Use Method II if a more refined calculation of Dc, is desired by the station (i.e., use of actual release point parameters with annual or actual meteorology to obtain release-specific X/Qs) or if Method I or Method IA predicts a dose rate greater than the Part A Control limit to determine if it had actually been exceeded during a short time interval.
See Part B, Section 7.2.3 for basis.3.6.1 Method I The Critical Organ Dose Rate to an off-site receptor and elevated release conditions can be determined as follows: Dco(e) = (Q

The critical organ dose rate will be determined based on the location (site boundary, nearest resident, or farm) of receptor pathways as identified in the most recent annual land use census, or by conservatively assuming the existence of all pathways (ground plane, inhalation, ingestion of stored and leafy vegetables, milk, and meat) at an off-site location of maximum potential dose. Concurrent meteorology with the release period may be utilized for determination of atmospheric dispersion factors in accordance with Part B, Sections 7.3.2 and 7.3.3 for the release point (either ground level or vent stack) from which recorded effluents have been discharged.
The maximum critical organ dose rates will consider the four age groups independently, and take no credit for a shielding factor (SF) associated with residential structures.

B.3-27 ODCM Rev. 32 1 3.10 Method to Calculate Direct Dose from Site Operations Part A Control C.8.1.1 restricts the dose to the whole body or any organ to any member of the public from all uranium fuel cycle sources to 25 mrem in a calendar year (except the thyroid, which is limited to 75 mrem). Direct radiation from contained sources is required to be included in the assessment of compliance with this standard.3.10.1 Method 'The direct dose from the plant and Dry Fuel Storage (DFS) facilities will be determined by obtaining the dose from TLD locations situated on-site near potential sources of direct radiation, as well as those TLDs near the site boundary which are part of the plant operations and DFS environmental monitoring programs, and subtracting out the dose contribution from background.
Realistic occupancy factors should be applied to the estimation of annual dose to MEMBERS OF THE PUBLIC from Seabrook site operations.
Additional methods to calculate the direct dose may also be used to supplement the TLD information, such as high pressure ion chamber measurements, or analytical design calculations of direct dose from identified sources (such as solid waste storage facilities).
The dose determined from direct measurements or calculations will be related to the nearest real person off-site, as well as those individuals on-site involved in activities at either the Science and Nature Center or the Rocks boat landing, to assess the contribution of direct radiation to the total dose limits of Part A Control C.8.1.1 in conjunction with liquid and gaseous effluents.
For TLD assessments, the direct dose from plant area sources and DFS operations is determined by comparing the expected annual data for environmental TLD locations near the site boundary or public access areas to pre-operational data for the same locations.
The expected measurement for each indicator TLD location is determined as a function of the observed change in exposure rate at the control location TLD data (i.e., TLD locations more than 20 km from the site) for the current year and for the pre-operational monitoring program as follows: Xe = Xp xmc PC where: Xe = the expected TLD measurement for a given location, independent of any direct radiation from station facilities, Xp = the average pre-operational TLD' measurement response for the location of interest, 1 For the DFS, the pre-operational period includes those DFS environmental monitoring program TLD measurements made prior to fuel assemblies being moved into the DFS facility.B.3-28 ODCM Rev. 32 Xmc = the average TLD measurement for the control TLD locations (TL-36 through TL-38 and TL-40 through TL-42)2 in the current year, and X = the average TLD measurement for the control TLD locations (TL-36 through TL-38 and TL-40 through TL-42) in the pre-operational period 2 All doses are expressed in mR/91days.
This is the length of a standard quarter which places all quarterly TLD field measurement on equivalent time intervals for comparisons.
The current year annual average measurement for each TLD location (Xo) is compared to the expected TLD measurement (Xe) by taking the difference between the current measurement value and the expected value (Xo -Xe). A direct dose component due to plant or DFS operations is assumed if the difference between the current annual average TLD measurement (Xo) and the calculated expected value for a TLD location (Xe) is greater than 20% (unless an evaluation can show that this difference is not plant related):[(X -Xe)/Xe > 0.2]For those measurements determined to reflect an increase due to plant or DFS operations, the net dose is estimated as the difference between the observed location value and the expected value (Xo -Xe).The 20% criterion in increased dose is selected based on its similar use as a significance criterion in NUREG-1301 (Land Use Control 3/4.12.1, Action b). The 20% increase criteria is also related to the ability of the TLDs to differentiate a true positive increase above a fluctuating background in the low dose ranges associated with environmental TLD measurements (20% is in the range of the typical 3-sigma counting statistics on the TLD readouts).
2 Control location TL-39 was not included since it has been moved from its original pre-operational location.Control locations can be added or removed from the assessment if their locations or nearby environments are altered from their baseline conditions.
B.3-29 ODCM Rev. 32 1 3.11 Dose Projections Part A Controls C.6.3.1 and C.7.4.1 require that appropriate portions of liquid and gaseous radwaste treatment systems, respectively, be used to reduce radioactive effluents when it is projected that the resulting dose(s) would exceed limits which represent small fractions of the "as low as reasonably achievable" criteria of Appendix I to 10 CFR Part 50. The surveillance requirements of these Part A Controls state that dose projections be performed at least once per 31 days when the liquid radwaste treatment systems or gaseous radwaste treatment systems are not being fully utilized.Since dose assessments are routinely performed at least once per 31 days to account for actual releases, the projected doses shall be determined by comparing the calculated dose from the last (typical of expected operations) completed 31-day period to the appropriate dose limit for use of radwaste equipment, adjusted if appropriate for known or expected differences between past operational parameters and those anticipated for the next 31 days.3.11.1 Liquid Dose Projections The 31-day liquid dose projections are calculated by the following:
- a. Determine the total body Dtb and organ dose Dmi, (Equations 3-1 and 3-2, respectively) for the last typical completed 31-day period. The last typical 31-day period should be one without significant identified operational differences from the period being projected to, such as full power operation vs. periods when the plant is shut down. For periods with identified operational differences, skip to subsection 3.11. .e. below.b. Calculate the ratio (R 1) of the total estimated volume of batch releases expected to be released for the projected period to that actually released in the reference period.c. Calculate the ratio (R 2) of the estimated gross primary coolant activity for the projected period to the average value in the reference period. Use the most recent value of primary coolant activity as the projected value if no trend in decreasing or increasing levels can be determined.
- d. Determine the projected dose from: Total Body: Dtb pr = Dtb .R 1 .R2 Max. Organ: Dmo pr Dm, .RI .R2 e. During periods when significant operational differences are identified, such as shutdowns vs. normal power operations, or when specific treatment components are expected to be bypassed or out of service for repair or maintenance, the projected dose should be based on an assessment of the expected amount of radioactivity that could be discharged, both through treated and any untreated pathways, over the next 31 days. Specific consideration should be given to effluent streams and treatment systems noted on Figure B.6-1. The volume of liquid to be released, the current or projected maximum radioactivity concentration in the effluent streams either prior to treatment or at the point of release to the environment, and the duration of expected release evaluations should be estimated as part of the projection of offsite dose.B.3-30 ODCM Rev. 32 1 For these periods outside the bounds of steps 3.11.1 .a. when significant operational differences exist from the last reference period, the projected dose to the total body Dtb and organ dose Din 0 shall use Equations 3-1 and 3-2, respectively to project dose for each definable time segment of release evolution and summed over the next 31 days. The radioactive release quantity, Qi, in equations 3-1 and 3-2 represents the estimated quantity of radionuclide "i" estimated to be released over the next 31 days, or during short time periods for defined plant operational evaluations, based on expected volumes, concentrations and treatment options to be applied.The EMS software can also be used to perform monthly projected dose calculations as described in Appendix C. The methodology applied by EMS in projecting liquid doses is outlined in Section 2.7 of Attachment 4 to Appendix C (EMS Technical Reference Manual).3.11.2 Gaseous Dose Projections I1. For the gaseous radwaste treatment system, the 31-day dose projections are calculated by the following:
- a. Determine the gamma air dose Dyir (Equation 3-6a), and the beta air dose Dar (Equation 3-7a) from the last typical 31-day operating period. The last typical 31-day period should be one without significant identified operational differences from the period being projected to, such as full power steady state operation vs.periods when the plant is shutdown.
For periods with identified operational differences, skip to subsection 3.11.2.2.e.
below.b. Calculate the ratio (R3) of anticipated number of curies of noble gas to be released from the hydrogen surge tank to the atmosphere over the next 31 days to the number of curies released in the reference period on which the gamma and beta air doses are based. If no differences between the reference period and the next 31 days can be identified, set R3 to 1.c. Determine the projected dose from: Gamma Air: r = Dir Beta Air: Dl pr -Dfr. R3 2. For the ventilation exhaust treatment system, the critical organ dose from iodines, tritium, and particulates are projected for the next 31 days by the following:
- a. Determine the critical organ dose Dco (Equation 3-8a) from the last typical 3 1-day operating period. (If the limit of Part A Control C.7.4.1.c (i.e., 0.3 mrem in 31 days)is exceeded, the projected controlled area annual total effective dose equivalent from all station sources should be assessed to assure that the 10 CFR 20.1301 dose limits to members of the public are not exceeded.)*
.The last typical 3 1-day period should be one without significant identified operational differences from the period being projected to, such as full power steady state operation vs. periods when the plant is shutdown.
For periods with identified operational differences, skip to subsection 3.11.2.2.e.

- b. Calculate the ratio (R 4) of anticipated primary coolant dose equivalent 1-131 for the next 31 days to the average dose equivalent 1-131 level during the reference period.Use the most current determination of DE 1-131 as the projected value if no trend can be determined.
- c. Calculate the ratio (R 5) of anticipated primary system leakage rate to the average leakage rate during the reference period. Use the current value of the system leakage as an estimate of the anticipated rate for the next 31 days if no trend can be determined.
- d. Determine the projected dose from: Critical Organ: Dc, pr = Dc. .R4. R5 e. During periods when significant operational differences are identified, such as shutdowns vs. normal power operations, or when specific treatment components are expected to be bypassed or out of service for repair or maintenance, the projected dose should be based on an assessment of the expected amount of radioactivity that could be discharged, both through treated and any untreated pathways, over the next 31 days. Specific consideration should be given to effluent streams and treatment systems noted on Figure B.6-2. The volume or flow rate of gas to be released, the current or projected maximum radioactivity concentration in the effluent streams either prior to treatment or at the point of release to the environment, and the duration of expected release evaluations should be estimated as part of the projection of offsite dose.For these periods outside the bounds of steps 3.11.2.1.a or 3.11.2.2.a.
when significant operational differences exist from the last reference period, the projected air dose from gamma and beta emissions from noble gases (Equations 3-6 and Equations 3-7, respectively), or from iodines, tritium, and particulates (Equations 3-8) shall use the referenced equations to project dose for each definable time segment of release evolution and summed over the next 31 days. The radioactive release quantity, Qi in the dose equations represents the estimated quantity of radionuclide "i" estimated to be released over the next 31 days, or during short time periods for defined plant operational evaluations, based on expected volumes, concentrations and treatment options to be applied.3. Alternate Projection Method for Use with Containment Ventilation Exhaust Treatment System (Charcoal Filters)During periods when the Containment Building air needs to be vented to the atmosphere, the decision to use the Containment charcoal filter train to exhaust Containment air can be based on dose conversion factors and critical organ dose equation that reflect only those real exposure pathways in the offsite environment as indicated by the annual Land Use Census. This reduces the excess conservatism associated with the standard Method I assumptions that all typical (potential) exposure pathways (including milk) may exist at the most limiting atmospheric dispersion point off site.B.3-32 ODCM Rev. 32 I In place of the dose conversion factors found in Table B. 1-12, and critical organ dose equation 3-8a for Dco, Chemistry Department technical evaluation CHSTID 02-004 contains the dose conversion factors (DFG) and critical organ dose equation which were developed in the same manner as the current Method I factors and time dependent dose equation, but which Utilize the most recent Land Use Census data to define which exposure pathways and identified receptor locations exist. CHSTID 02-004 documents the development of this alternate dose projection method. After the Land Use Census is performed each year, and before application to any Containment venting evolution, CHSTID 02-004 will be reviewed to see if any new receptor location impacts the selection of controlling dose location.The EMS software can also be used to perform monthly projected dose calculations as described in Appendix C. The methodology applied by EMS in projecting gaseous dose is outlined in Section 3.8 of Attachment 4 to Appendix C (EMS Technical Reference Manual).B.3-33 ODCM Rev. 32 1
- Note: This action is based on the assumption that tritium is the controlling nuclide for whole body exposures through the inhalation pathway. Maximum annual average on-site X/Q's for station effluent release points are approximately 100 times the values used for the site boundary dose calculations.
However, the site boundary doses calculated by the ODCM for iodines, tritium, and particulates with half lives greater than 8 days, includes all potential off-site exposure pathways.
For tritium, the inhalation pathway only accounts for 10% of the total dose contribution being calculated.
As a result, if the monthly calculation indicates that the site boundary maximum organ dose reached 0.3 mrem, the on-site maximum dose due to inhalation would be approximately 3.0 mrem for this period. If this were projected to continue for a year with a 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> occupancy factor applied, the projected inhalation whole body dose would be approximately 8 mrem, or 8% of the 10 CFR 20.1301 limit. This is a reasonable trigger value for the need to consider the dose contribution from all station sources to members of the public in controlled areas.B.3-34 ODCM Rev. 32 I 3.12 Method to Calculate Total Dose From Plant Operations ODCM Control C.8.1.1 restricts the annual dose to the whole body or any organ of a member of the public from all uranium fuel cycle sources (including direct radiation) to 25 mrem (except the thyroid, which is limited to 75 mrem). These cumulative dose contribution limits from liquids and gaseous effluents, and direct radiation, implement the Environmental Protection Agency (EPA) 40 CFR 190, "Environmental Standards for the Uranium Fuel Cycle." 3.12.1 Method Compliance with the Seabrook Station Effluent Controls dose objectives for the maximum individual, as calculated by the methods described in sections B.3.2, B.3.3, B.3.7, B.3.8, B.3.9 of the ODCM also demonstrates compliance with the EPA limits to any member of the public. This indirect determination of compliance is based on the fact that the Effluent Control liquid and gaseous dose objectives are taken from 10 CFR 50, Appendix 1, and represent lower values than the 40 CFR 190 dose limits. Direct radiation dose from contained sources is not expected to be a significant contributor to the total dose to areas beyond the site boundary.
If the operational dose objectives in the Seabrook ODCM Effluent Controls C.6.2.1 .a, C.6.2.1 .b, C.7.2.1 .a, C.7.2.1 .b, C.7.3.1 .a, or C.7.3.1 .b are determined to be exceeded by a factor of two, a Special Report must be prepared.
The purpose of this Special Report is to determine by direct assessment if the cumulative dose (calendar year) to any member of the public (real individual) from all sources is within the limits of the Total Dose Control C.8.1.1.In addition, section A. 10.2, "Annual Radioactive Effluent Release Report," requires that an assessment of radiation doses to the likely most exposed member of the public from all effluent and direct radiation sources be included for the previous calendar year to show compliance with 40 CFR 190 [equivalent limits to 10 CFR 72.104(a) when considering Dry Fuel Storage].When required, the total dose to a member of the public will be calculated for all significant effluent release points for all real pathways, including direct radiation.
Only effluent releases from Seabrook Station, including direct radiation from the Dry Fuel Storage facility, need be considered since no other uranium fuel cycle facilities exist within five miles. EPA has determined that for fuel cycle facilities separated by more than five miles, their contribution to each other's total dose would not be significant and cause dose Standard for the Uranium Fuel Cycle to be exceeded.
The calculations will be based on the liquid and gaseous Methods II dose models as described in Section B.3, including usage factors and other documented site-specific parameters reflecting realistic assumptions, where appropriate.
The liquid and gaseous effluent Method I models are derived from the methods given in Regulatory Guide 1.109, Rev. 1, October 1977.The direct radiation component from the plant and the Dry Fuel Storage facility can be determined using environmental TLD results as noted in Section B.3.10.1 (or alternately, high pressure ion chamber measurements or analytical design calculations for estimating the direct radiation dose from identified contained radioactive sources within the facility).
B.3-35 ODCM Rev. 32 4.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM (REMP)The Radiological Environmental Monitoring Program consist of two interconnected sample collection and measurement schedules that look for environmental influences from: (1) plant operations which release to the environment radioactive materials in liquid and gaseous effluents, and direct radiation from plant facilities inside the power block Protected Area, and (2) direct radiation from used fuel placed in the Dry Fuel Storage (DFS) facility located in the West Southwest sector approximately 0.38 miles from the Containment Building.
Several monitoring locations provide data that are shared or used in the assessment of both plant and DFS operations 4.1 Plant Operations REMP The plant operations related radiological environmental monitoring stations are listed in Table B.4-1. The locations of the stations with respect to the Seabrook Station are shown on the maps in Figures B.4-1 to B.4-6.All radiological analyses for environmental samples are performed at a contractor laboratory.
The contractor laboratory participates in an Interlaboratory Comparison Program for all relevant species in an aqueous (water) matrix. An independent vendor (Analytics) supplies the remaining cross check samples. These samples are presented on an air filter and in milk and water matrices.Pursuant to Part A Surveillance S.9.2.1, the Land Use Census will be conducted "during the growing season" at least once per 12 months. The growing season is defined, for the purposes of the Land Use Census, as the period from June 1 to October 1. The method to be used for conducting the census will consist of one or more of the following, as appropriate:
door-to-door survey, visual inspection from roadside, aerial survey, or consulting with local agricultural authorities.
Technical Specification 6.8.1.3 and Part A, Section 10.1 of the ODCM require that the results of the Radiological Environmental Monitoring Program be summarized in the Annual Radiological Environmental Operating Report "in the format of the table in the Radiological Assessment Branch Technical Position, Revision 1, 1979." The general table format will be used with one exception and one clarification, as follows. The mean and range values will be based not upon detectable measurements only, as specified in the NRC Branch Technical Position, but upon all measurements.
This will prevent the positive bias associated with the calculation of the mean and range based upon detectable measurements only. Secondly, the Lower Limit of Detection column will specify the LLD required by ODCM Table A.9.1-2 for that radionuclide and sample medium.4.2 Dry Fuel Storage Facility Monitoring Program The DFS radiological environmental monitoring stations are listed in Table B.4-2. The measurement locations with respect to the Seabrook site area are shown on Figures B.4-4 and B.4-7.The results of the Dry Fuel Storage environmental monitoring are summarized and reported in the Annual Radiological Environmental Operating Report.B.4-1 ODCM Rev. 34 TABLE B.4-1 RADIOLOGICAL ENVIRONMENTAL MONITORING STATIONS(a)

Samples are not required from all stations listed during any sampling interval (FH = Fish; HA = Lobsters; MU = Mussels).Table A.9.1-1 specifies that "one sample of three commercially and recreationally important species" be collected in the vicinity of the plant discharge area, with similar species being collected at a control location. (This wording is consistent with the NRC Final Environmental Statement for Seabrook Station.)
Since the discharge area is off-shore, there is a great number of fish species that could be considered commercially or recreationally important.
Some are migratory (such as striped bass), making them less desirable as an indicator of plant-related radioactivity.
Some pelagic species (such as herring and mackerel) tend to school and wander throughout a large area, sometimes making catches of significant size difficult to obtain. Since the collection of all species would be difficult or impossible, and would provide unnecessary redundancy in terms of monitoring important pathways to man, three fish and invertebrate species have been specified as a minimum requirement.
Samples may include marine fauna such as lobsters, clams, mussels, and bottom-dwelling fish, such as flounder or hake. Several similar species may be grouped together into one sample if sufficient sample mass for a single species is not available after a reasonable effort has been made (e.g., yellowtail flounder and winter flounder)(d) Monitoring program defined in Part A of ODCM does not require this sample location; food product sampling is being implemented in lieu of an insufficient number of milk locations.(e) Indicates locations shared with DFS monitoring.

Example setpoint calculations are provided for each of the required effluent monitors.5.1 Liquid Effluent Instrumentation Setpoints Part A Control C.5.1 requires that the radioactive liquid effluent instrumentation in Table A.5.1-1 of Part A have alarm setpoints in order to ensure that Part A Control C.6.1.1 is not exceeded.
Part A Control C.6.1.1 limits the activity concentration in liquid effluents to ten times the ECL values in 10 CFR 20, Appendix B, Table 2, and a total noble gas MPC.5.1.1 Liquid Waste Test Tank Monitor (RM-6509)The liquid waste test tank effluent monitor provides alarm and automatic termination of release prior to exceeding ten times the concentration limits specified in 10 CFR 20, Appendix B, Table 2, Column 2 to the environment.
It is also used to monitor discharges from various waste sumps to the environment.
5.1.1.1 Method to Determine the Setpoint of the Liquid Waste Test Tank Monitor (RM-6509)The alarm setpoint is based on ensuring that radioactive effluents in liquid waste are in compliance with Control limits which are based on the concentration limits in Appendix B to 10 CFR 20. The alarm point depends on available dilution flow through the discharge tunnel, radwaste discharge flow rate from the test tanks, the isotopic composition of the liquid waste, and the monitor response efficiency and background count rate applicable at the time of the discharge.
The alarm/trip setpoint is determined prior to each batch release taking into account current values for each variable parameter.
The following steps are used in determining the monitor setpoint: First, the minimum required dilution factor is determined by evaluating the isotopic analysis of each test tank to be released along with ECL requirements for each radionuclide.
The most recent analysis data for tritium and other beta emitters that are analyzed only monthly or quarterly on composite samples can be used as an estimate of activity concentration in the tank to be released.
For noble gases, the Control limit (C.6.1. l) is defined as 2E-04 liCi/mI total for all dissolved and entrained gases. Therefore, DFmin = Ci or CNG , whichever is larger. (5-3)10ECLi 2E -04 Where: DFmin Minimum required dilution factor necessary to ensure that the sum of the ratios for each nuclide concentration divided by its ECL value is not greater than 10 (dimensionless).
B.5-1 ODCM Rev. 33 Ci Activity concentration of each radionuclide
'T' (except noble gases) determined to be in the test tank (pCi/ml).
This includes tritium and other non gamma emitting isotopes either measured or estimated from the most recent composite analysis.Cng The sum of all dissolved and entrained noble gases identified in each test tank (pgCi/ml).
ECLi Effluent concentration limit (ECL) for radionuclide I"i (except for dissolved and entrained noble gas) in jiCi/ml as specified in 10 CFR 20, Appendix B, Table 2.See ODCM, Appendix B, for a listing. In the event that no activity is expected to be discharged, or can be measured in the system, the liquid monitor setpoint should be based on the most restrictive ECL for an "unidentified" mixture or a mixture known not to contain certain radionuclides as given in 10 CFR 20, Appendix B, notes.2E-04 The total dissolved and entrained noble gas Technical Specification concentration limit in liquid effluents from the plant (gCi/ml).Next, the available dilution flow through the discharge tunnel (Fd), or a conservative estimate for it, is divided by the minimum dilution factor (DFmin) to determine the maximum allowable discharge flow rate (Fmax) that the test tanks could be released at without exceeding the ECL limits, assuming no additional radioactive flow paths are discharging at the time of release of the test tanks. Therefore, Fmax -Fd DFmin Where: Fmax = The maximum allowable discharge flow rate from the test tank past the monitor which would equate to the Control concentration limit for the radioactivity mixture determined to be in the test tank (gpm).Fd The actual or conservative estimate of the flow rate out of the discharge tunnel (gpm).B.5-2 ODCM Rev. 33 For Waste Test Tank (WTT) releases, tritium is expected to be the radionuclide with the highest concentration, and therefore requires the highest dilution flow in order to satisfy the discharge concentration limits. Unlike concentrations of other dissolved or suspended radionuclides, tritium concentrations are not expected to vary because they are unaffected by plant cleanup systems used to reduce or control waste radioactivity levels. As such, events that cause sudden increases in the concentrations of other dissolved or suspended radionuclides, such as changes in waste cleanup efficiencies, crud bursts or failed fuel fractions would not change the tritium concentrations.
As long as the minimum required dilution factor (DFmin) for all radionuclides present in the liquid waste is satisfied, the alarm setpoint for the Waste Test Tank monitor need only consider the potential changes to the concentrations of detectable gamma-emitting radionuclides.
Therefore, the required dilution for detectable activity by the WTT monitor can be determined by applying the definition of DFmin (given in equation (5-3)) to only the gamma-emitting radionuclides present in the waste.DFmin, = Y (Ci,/10ECLi)
(5-3a)Where: DFminy Minimum required dilution factor necessary to ensure that the sum of the ratios for the concentration of each gamma-emitting radionuclide to the respective ECL value is not greater than 10 (dimensionless).
Qi Activity concentration of each detectable gamma-emitting radionuclide "i" in the mixture (liCi/ml).
ECLi As defined previously.
As in the determination of Fmax for the total radioactivity mixture, the maximum allowable discharge flow rate that the waste from the test tanks could be released at without exceeding the concentration limit for gamma-emitters, Fmax'y, is obtained by dividing the discharge tunnel flow, Fd, by DFminy/. This determination is based on the assumption that there are no additional discharges of liquid waste at the time of release from the test tanks. Therefore, Fmax.y, = Fd/ DFminy Where: Fmaxy The maximum allowable discharge flow rate from the test tank past the monitor which would equate to the control concentration limit for the gamma radioactivity mixture determined to be in the test tank (gpm).Fd The actual or conservative estimate of the flow rate out of the discharge tunnel (gpm).B.5-3 ODCM Rev. 33 The selection of the actual discharge flow rate (Fm) from the test tanks compared to the maximum allowable discharge rate based on all radionuclides that are present (Fmax) and the maximum allowable discharge rate based on only gamma-emitting radionuclides that are present (Fmax-y) must satisfy the following:
Fm < Fmax
- ftt < Fmaxy *ftt Where the ftt represents an administrative fraction of the maximum allowable discharge flow from the test tanks. This fraction provides additional margin in meeting ECL limits for non-gamma emitters (such as tritium) at the discharge point to the ocean when other flow paths may contribute to the total site release at the time of tank discharges and minimum dilution flow conditions exist.With the above conditions on discharge and dilution flow rates satisfied, the alarm/trip setpoint for the monitor which corresponds to the maximum allowable concentration at the point of discharge is determined as follows: Rsetpoint
= fl x Fd xzC)i (5-1)Fm x DFmi, Where: Rsetpoint The maximum allowable alarm/trip setpoint for an instrument response ([tCi/ml) that ensures the limiting concentration at the point of discharge is not exceeded.f, The fraction of the total contribution of ECL at the discharge point to be associated with the test tank effluent pathway, where f 2 , 1f 3 , f 4 , and f 5 , are the fractions for the Turbine Building Sump, Steam Generator Blowdown, Primary Component Cooling and Water Treatment Effluent (Condensate Polishing System) pathways contribution to the total, respectively (fl+f 2+f 3+f 4+f 5 < 1). Each of the fractions may be conservatively set administratively such that the sum of the fractions is less than 1. This additional margin can be used to account for the uncertainty in setpoint parameters such as estimated concentration of non gamma emitters that are based on previous composite analyses of the waste stream.B.5-4 ODCM Rev. 33 5.1.1.2 Liquid Waste Test Tank Monitor Setpoint Example The radioactivity concentration of each radionuclide, Ci, in the waste test tank is determined by analysis of a representative grab sample obtained at the radwaste sample sink, and analyzed prior to release for gamma emitters, or as part of a composite analysis for non gamma emitters.
The maximum allowable instantaneous effluent concentrations (i.e., ten time the ECL values in 10 CFR 20, Appendix B, Table 2) are used to illustrate a monitor setpoint determination.
This setpoint example is based on the following data: Ten Times i Ci (gCi/ml) ECLi (tCi/ml) ECLI (giCi/ml)Cs-134 2.15E-05 9E-07 9E-06 Cs-137 7.48E-05 1E-06 IE-05 Co-60 2.56E-05 3E-06 3E-05 H-3 1.50E-01 1E-03 1E-02 The minimum required dilution factor for this mix of radionuclides (including beta-emitters) is: DFmin = .'

The cooling water tunnel discharge dilution flow rate (Fd) can typically vary from approximately 8,800 to 412,000 gpm depending on the operating status of the plant. In this example, if the dilution flow (Fd)is taken as 412,000 gpm, the maximum allowable discharge rate (Fmax) is: Fd F m ax = --DFmin 412,000= --gpm 26= 15,846 gpm Next, the required dilution factor for only gamma emitters in the mix is: 2.15E -05 7.48E -05 2.56E -05 DFminy Z 9E-06 E -05 3E-05 The maximum allowable discharge flow rate (Fmaxy) considering only gamma emitters is given as: Fm~v Fd 412,000 Fmaxy -= F-412,00gpm
= 37,455 gpm DFminy gp1 B.5-5 ODCM Rev. 33 With the selected release rate from the test tank set at 150 gpm, and the administrative flow fraction (ftt) assumed in this example to be 0.7, the condition for the control concentration limits is met since: Fm (equal to 150) < Fmax (equal to 15,846 gpm) x ftt (set at 0.7)< Fmaxy (equal to 37,455 gpm x Ftt (set at 0.7)150 < 11092 < 26219 and the monitor response due to the mix of the gamma emitters is: Cyi (jtCi/ml)Cs-134 2.15E-05 Cs-137 7.48E-05 Co-60 2.56E-05:C .= 1.22E -04 pCi/ml Under these conditions, the alarm/trip setpoint for the liquid radwaste discharge monitor is: Rsetpoint

= 0.4 x -1 0 0 0 x 1.22E -04= 1.22E -02 jCi/ml In this example, the alarm/trip setpoint of the liquid radwaste discharge monitor can be put at 1.22E-02 ptCi/ml above background.
For the example, it is assumed that the test tank release pathway will be limited to only 40% of the total site discharge allowable concentration.
5.1.2 Turbine Building Drains Liquid Effluent Monitor (RM-6521)The Turbine Building drains liquid effluent monitor continuously monitors the Turbine Building sump effluent line. The only sources to the Sump Effluent System are from the secondary steam system. Activity is expected in the Turbine Building Sump Effluent System only if a significant primary-to-secondary leak is present. If a primary-to-secondary leak is present, the activity in the sump effluent system would be comprised of only those radionuclides found in the secondary system, with reduced activity from decay and dilution.B.5-6 ODCM Rev. 33 The Turbine Building drains liquid effluent monitor provides alarm and automatic termination of release prior to exceeding ten times the concentration limits specified in 10 CFR 20, Appendix B, Table 2, Column 2 to the environment.
The alarm setpoint for this monitor will be determined using the same method as that of the liquid waste test tank monitor if the total sump activity is greater than the ECL, as determined by the most recent grab sample isotopic analysis.
If the total activity is less than the ECL, the setpoints of RM-6521 are calculated as follows: High Trip Monitor Setpoint (tCi/ml) f 2 (DF') ("unidentified mix ECL" (jtCi/ml))
(5-21)where: Circulating water flow rate (gpm)DF' = Flow rate pass- monitor (gpm)unidentified mix ECL = most restrictive ECL value (jiCi/ml) for an unidentified mixture or a mixture known not to contain certain radionuclides as given in 10 CFR 20, Appendix B, Notes.f2 1 -(fl + f 3 + f 4 + fs); where the f values are described above.In addition, a warning alarm setpoint can be determined by multiplying the high trip alarm point by an administratively selected fraction (as an example, 0.25).Warning Alarm Monitor Setpoint = (Monitor Sepoint) (0.25)(PCi/ml)5.1.3 Steam Generator Blowdown Liquid Sample Monitor (RM-6519)The steam generator blowdown liquid sample monitor is used to detect abnormal activity concentrations in the steam generator blowdown flash tank liquid discharge.
The alarm setpoint for the steam generator blowdown liquid sample monitor, when liquid is to be discharged from the site, will be determined using the same approach as the Turbine Building drains liquid effluent monitor.For any liquid monitor, in the event that no activity is expected to be discharged, or can be measured in the system, the liquid monitor setpoint should be based on the most restrictive ECL for an "unidentified" mixture or a mixture known not to contain certain radionuclides given in 10 CFR 20, Appendix B notes.B.5-7 ODCM Rev. 33 5.1.4 PCCW Head Tank Rate-of-Change Alarm Setpoint A rate-of-change alarm on the liquid level in the Primary Component Cooling Water (PCCW)head tank will work in conjunction with the PCCW radiation monitor to alert the operator in the Main Control Room of a leak to the Service Water System from the PCCW System. For the rate-of-change alarm, a setpoint is selected based on detection of an activity level equivalent to 10-8 ýtCi/ml in the discharge of the Service Water System. The activity in the PCCW is determined in accordance with the liquid sampling and analysis program described in Part A, Table A.6.1-1 of the ODCM and is used to determine the setpoint.The rate-of-change alarm setpoint is calculated from: RCset = lxl0 8 9 SWF
- 1 (5-23)PCC (gal) = (m DCi) (gal) ( ml hr m hr Pc where: RCset The setpoint for the PCCW head tank rate-of-change alarm (in gallons per hour).lx10-s The minimum detectable activity level in the Service Water System due to a PCCW to SWS leak (ItCi/ml).
SWF = Service Water System flow rate (in gallons per hour).PCC Primary Component Cooling Water measured (decay corrected) gross radioactivity level (itCi/ml).
As an example, assume a PCCW activity concentration of lx10-5 PtCi/ml with a service water flow rate of only 80 percent of the normal flow of 21,000 gpm. The rate-of-change setpoint is then: RCt= I -UC' 0 1.Ox106 gph (1/lxl0-5
)ml ml RCs -= 1000 gph As a result, for other PCCW activities, the RCset which would also relate to a detection of a minimum service water concentration of 1x10-8 jCi/ml can be found from: lxl0-5xl1000gph RCset -(5-24)PCC B.5-8 ODCM Rev. 33 5.1.5 PCCW Radiation Monitor The PCCW radiation monitor will alert the operator in the Main Control Room of a leak to the PCCW System from a radioactively contaminated system.The PCCW radiation monitor alarm is based on a trend of radiation levels in the PCCW System. The background radiation of the PCCW is determined by evaluating the radiation levels over a finite time period. The alert alarm setpoint is set at 1.5 x background, and the high alarm setpoint is set at 2 x background, per Technical Specification Table 3.3-6.5.1.6 Water Treatment Liquid Effluent (CPS Rad Monitor RM-6473)The Water Treatment Liquid Effluent monitor is used to detect abnormal activity concentrations in waste liquid discharges to the Transition Structure from tank Tk-32 (CPS Neutralization Tank or equivalentl), tank Tk-274 (Low Conductivity Tank) and megarinse wash water from the Condensate Polishing System (CPS) demineralizer regeneration cycle.The CPS Rad monitor provides alarm and automatic termination of release prior to exceeding the concentration limits specified in 1OCFR20, Appendix B, Table 2, Column 2 to the environment.
The alarm setpoint for this monitor will be determined using the same method as that of the Liquid Waste Test Tank Monitor (see Section 5.1.1.1) if the total activity expected to be discharged is greater than 10 percent of ECL, as determined by the most recent grab sample isotopic analysis.
If the total activity is less than 10 percent of ECL, the setpoints of RM-6473 can be calculated as follows: High Trip Monitor Setpoint (jiCi/ml) f5 (DF') ("unidentified mix ECL" (pLCi/ml))
where: DF' Circulating water flow rate (gpm)Flow rate pass- monitor (gpm)unidentified mix ECL = most restrictive ECL value (RCi/ml) for an unidentified mixture or a mixture known not to contain certain radionuclides as given in 1OCFR20, Appendix B, Notes.f5 1 -(fl + f 2 + f 3 + f 4); where the f values are described in Section 5.1.1.1 above.In addition, a warning alarm setpoint can be determined by multiplying the high trip alarm point by an administratively selected fraction (as an example, 0.25).' The Condensate Polishing System (CPS) has the provision to discharge temporary tanks as batch releases through the same discharge path as the Neutralization Tank (TK-32). The requirements for discharges from a temporary tank through this CPS pathway are equivalent to those of the Neutralization Tank.B.5-9 ODCM Rev. 33 Warning Alarm Monitor Setpoint (/uCi/ml)( High Trip (0.25)

B.5-12 ODCM Rev. 33 5.2.1.2 Plant Vent Wide Range Gas Monitor Setpoint Example for Limiting Case The following setpoint example for the plant vent wide range gas monitors demonstrates the use of equations 5-5 and 5-6 for determining setpoints.
Evaluations of potential releases rates associated with the limiting offsite dose rates (Control C.7. 1.1 .a) have been made considering different noble gas mixes related to normal operations, observed periods with fuel defects, and potential UFSAR accident conditions.
The bounding noble gas mix case for setpoint alarm indications was found to be related to projected fuel gap activity at the time of shutdown from power operations (UFSAR Table 15.7-20).
By setting the maximum alarm setpoint in accordance with this assumed mix, other potential or realistic release conditions will not create an effluent discharge at or above the limiting offsite dose rates without the monitor going into alarm.This limiting setpoint example is based on the following data (see Table B.I-10 for DFBi(e) and DF 'i(e)): Q0 DFBi DF'i(e)(Ci mrem-_m 3 3 mrem-sec (_sec pCi- yr a Ci- yr Xe-138 2.52E+02 8.83E-03 1.20E-02 Kr-87 7.90E+O1 5.92E-03 1.38E-02 Kr-88 1.15E+02 1.47E-02 1.62E-02 Kr-85m 4.49E+O1 1.17E-03 2.35E-03 Xe-135 6.82E+I01 1.81E-03 3.33E-03 Xe- 133 3.23E+02 2.94E-04 5.83E-04 Kr-85 4.13E+00 1.61E-05 1.11 E-03 Xe-131m 1.15E+00 9.15E-05 5.37E-04 Xe-133m 4.67E+01 2.5 1E-04 1.12E-03 Xe- 135m 6.64E+O 1 3.12E-03 3.74E-03 B.5-13 ODCM Rev. 33 0i QDFBi j DF -(5-7)" Q, DFB, = (2.52E+02)(8.83E-03)

Therefore, the plant vent wide-range gas monitor should be set at no more than 8.47E+04 pCi/sec above background, or at some administrative fraction of the above value.B.5-15 ODCM Rev. 33 5.2.2 Waste Gas System Monitors (RM-6504 and RM-6503)Process radiation monitors in the waste gas system provide operational information on the performance of the system before its discharge is combined and diluted with other gas flows routed to the plant vent for release to the environment.
The setpoints for the waste gas system monitors are administratively set as small multiples of the expected activity concentration to provide operational control over unexpected changes in gas discharges from the system. Typically, the alert alarm setpoint for both monitors is placed at 1.5 times the expected activity concentration passing the monitor, with the high alarm trip set at 2.0 times the expected concentration flow.Under all conditions, the maximum allowable alarm trip shall not exceed a concentration equivalent to 62.5 jiCi/cm 3.This concentration limit, based on system design flow of 1.2 cfm, assures that any release from the waste gas system to the plant vent will not exceed the site boundary dose rate limits of Part A Control C.7.1.1 .a.5.2.3 Main Condenser Air Evacuation Monitor (RM-6505)The process radiation monitor on the main condenser air evacuation system provides operational information about the air being discharged.
The discharge typically occurs either directly from the turbine building during start up (hogging mode) or through the plant vent during normal operations.
During maintenance activities or other temporary operational conditions, discharges to the turbine roof may also occur. This process monitor is also used as an indicator of potential releases from the Turbine Gland Seal Condenser exhaust. Early indications of a potential release (i.e., monitor count rate at twice the normal background) should be evaluated by collecting a grab sample of the exhausts from both the main condenser and the Turbine Gland Seal Condenser.
The condenser air evacuation monitor is the most sensitive indicator of a primary to secondary leak in the plant steam generators.
Therefore, the operational setpoints for the air evacuation monitor are typically administratively set at small fractions of the values necessary to maintain the site boundary dose rate limits of Part A Control C.7.1.1. Station procedures for determining the condenser air evacuation monitor setpoints recognize the not to be exceeded ODCM determined maximum values. Typically when primary to secondary leakage is not present, the alert setpoint is 2 to 3 times background, with the high alarm set at 2.OE+03 cpm or a higher value corresponding to 30 gallons per day of primary to secondary steam generator leakage.Maximum allowable setpoint determinations assure that the site boundary dose rate limits of Part A Control C.7. 1.1 .a will not be exceeded.
For the air evacuation detector an efficiency of 1.87E + 08 cpm-cm 3/4Ci, (the AR-41 response value determined by HIPSTID 00-021), flow rates of 10 to 50 cfm and 10,000 cfm for the normal and hogging modes of operation, respectively, and assuming that all the response is due to the most restrictive noble gas mixture associated with fuel gap activity inventory at the end of power operations (same mixture as used for the limiting mixture for the plant vent Wide Range Gas Monitor setpoint given in section 5.2.1.2), the following examples illustrate the calculation of the limiting setpoint for different operational conditions.
B.5-16 ODCM Rev. 33 Case 1: For start-up operations (i.e., 10,000 cfm hogging flow to the Turbine Building roof), the maximum allowable alarm setpoint is calculated as: 1 RAE =D147 fg fgland where: RAE Release rate equivalent to the assigned fraction of the limiting offsite total body dose rate (p.Ci/sec) 147 500 (mrem -ptCi -m 3 i (1E + 06) (3.4E -06) yr -pCi -sec 500 = The site boundary limiting total body dose rate (mrem/yr) from all release points lE+06 = Number of pCi per gtCi (pCi/[tCi) 3.4E-06 Maximum off-site long-term average gamma atmospheric dispersion factor for ground level releases (sec/mi 2)DFBC Composite total body dose factor (defined for the WRGM in Section 5.2.1.2 to be equal to 4.86E-03 [mrem-m 3 /pCi-yr] for the limiting fuel gap activity mix)fg The fraction of the site boundary total body dose rate limit to be administratively assigned to monitored ground level releases (for this illustration

In this situation, the same release rate limit as calculated above (i.e., 6.36E+03 iiCi/sec) would apply. However, the reduced gas flow from 10,000 cfm down to 50 cfm would permit a higher alarm setpoint to be used.Monitor Response = RAE 1.87E + 08 cpm-cm 3/4Ci 2.36E + 04cm 3/ sec= (6.36E+03)

(1.87E + 08) (2.36E+04)
= 6.71E + 08 cpm The operation of the Main Condenser Evacuation System assumes 670 lbs./hour of steam flow through the Turbine Gland Seal Condenser exhaust (very small fraction of total steam flow), 1.5E+07 lbs./hour steam flow to the main condenser, and that the Turbine Gland Seal Condenser exhaust mostly air at a flow rate bf 1,800 cfm which goes directly to the Turbine Building Vents (does not pass RM-6505).
The main condenser offgas which goes past the Air Evacuation monitor during power operations is combined with other plant ventilation and process gas streams before being monitored by the WRGM and discharged to the atmosphere via the Plant Vent as a single release point.The maximum allowable setpoints during startup and normal power operations may be recalculated based on identified changes in detector efficiency, discharge flow rate, radionuclide mix distribution, or administrative apportionment of potential contributions from the plant vent and ground level release points following the methods identified in Part B, Section 8.5.B.5-19 ODCM Rev. 33 6.0 LIQUID AND GASEOUS EFFLUENT STREAMS, RADIATION MONITORS AND RADWASTE TREATMENT SYSTEMS Figure B.6-1 shows the liquid effluent streams, radiation monitors and the appropriate Liquid Radwaste Treatment System.

The noble gas releases will be determined by periodic noble gas grab samples. A ratio of main condenser air evacuation exhaust and turbine gland seal condenser exhaust noble gas will be determined periodically.

Appendix C provides the bases for the EMS software which is used to implement the dose and dose rate calculations indicated as Method IA.Method I may be used to show that the Part A RECP which limit off-site total body dose from liquids (C.6.2.1 and C.6.3.1) have been met for releases over the appropriate periods. The quarterly and annual dose limits in Part A Control C.6.2.1 are based on the ALARA design objectives in 1OCFR50, Appendix I Subsection 11 A. The minimum dose values noted in Part A Control C.6.3.1 are "appropriate fractions," as determined by the NRC, of the design objective to ensure that radwaste equipment is used as required to keep off-site doses ALARA.Method I was developed such that "the actual exposure of an individual
... is unlikely to be substantially underestimated" (10CFR5O, Appendix I). The definition, below, of a single"critical receptor" (a hypothetical or real individual whose behavior results in a maximum potential dose) provides part of the conservative margin to the calculation of total body dose in MethodI. Method H1 allows that actual individuals, associated with identifiable exposure pathways, be taken into account for any given release. In fact, Method I was based on a Method 11 analysis for a critical receptor assuming all principal pathways present instead of any real individual.
That analysis was called the "base case;" it was then reduced to form Method I. The general equations used in the base case analysis are also used as the starting point in Method 11 evaluations.
The base case, the method of reduction, and the assumptions and data used are presented below.The steps performed in the Method I derivation follow. First, the dose impact to the critical receptor [in the form of dose factors DFLitb (mrem/jiCi)]
for a unit activity release of each radioisotope in liquid effluents was derived. The base case analysis uses the general equations, methods, data and assumptions in Regulatory Guide 1.109 (Equations A-3 and A-7, Reference A). The liquid pathways contributing to an individual dose are due to consumption of fish and invertebrates, shoreline activities, and swimming and boating near the discharge point. A nominal operating plant discharge flow rate of 918 ft 3/sec was used with a mixing ratio of 0.10.The mixing ratio of 0.10 corresponds to the minimum expected prompt dilution or near-field mixing zone created at the ocean surface directly above the multiport diffusers. (Credit for additional dilution to the outer edge of the prompt mixing zone which corresponds to the I OF surface isotherm (mixing ratio .025) can be applied in the Method 11 calculation for shoreline exposures only since the edge of this isotherm typically does not reach the shoreline receptor points during the tidal cycle. The mixing ratio for aquatic food pathways in Method II assessments shall be limited to the same value (0.10) as applied in Method I for near-field mixing, or prompt dilution only.13.7-1 ODCM Rev. 24 The requirements for the determination of radiological impacts resulting from releases in liquid effluents is derived from 1OCFR50, Appendix I. Section HI.A.2 of Appendix I indicates that in making the assessment of doses to hypothetical receptors, "The Applicant may take account of any real phenomenon or factors actually affecting the estimate of radiation exposure, including the characteristics of the plant, modes of discharge of radioactive materials, physical processes tending to attenuate the quantity of radioactive material to which an individual would be exposed, and the effects of averaging exposures over time during which determining factors may fluctuate." In accessing the liquid exposure pathways that characterize Seabrook Station, the design and physical location of the Circulating Water Discharge System needs to be considered within the scope of Appendix I.Seabrook utilizes an offshore submerged multiport diffuser discharger for rapid dissipation and mixing of thermal effluents in the ocean environment.
The 22-port diffuser section of the Discharge System is located in approximately 50 to 60 feet of water with each nozzle 7 to 10 feet above the sea floor. Water is discharged in a generally eastward direction away from the shoreline through the multiport diffuser, beginning at a location over one mile due east of Hampton Harbor inlet. This arrangement effectively prevents the discharge plume (at least to the 1 degree or 40 to 1 dilution isopleth) from impacting the shoreline over the tidal cycle.Eleven riser shafts with two diffuser nozzles each form the diffuser and are spaced about 100 feet apart over a distance of about 1,000 feet. The diffusers are designed to maintain a high exit velocity of about 7.5 feet per second during power operations.
Each nozzle is angled approximately 20 degrees up from the horizontal plane to prevent bottom scour. These high velocity jets passively entrain about ten volumes of fresh ocean water into the near field jet mixing region before the plume reaches the water surface. This factor of 10 mixing occurs in a very narrow zone of less than 300 feet from the diffuser by the time the thermally buoyant plume reaches the ocean surface. This high rate of dilution occurs within about 70 seconds of discharge from the diffuser nozzles.The design of the multiport diffuser to achieve a 10 to 1 dilution in the near field jet plume, and a 40 to 1 dilution in the near mixing zone associated with the I degree isotherm, has been verified by physical model tests (reference "Hydrothermal Studies of Bifurcated Diffuser Nozzles and Thermal Backwashing
-Seabrook Station," Alden Research Laboratories, July 1977).During shutdown periods, when the plant only requires service water cooling flow, the high velocity jet mixing created by the normal circulating water flow at the diffuser nozzles is reduced. However, mixing within the discharge tunnel water volume is significantly increased (factor of about 5) due to the long transit time (approximately 50 hours5.787037e-4 days <br />0.0139 hours <br />8.267196e-5 weeks <br />1.9025e-5 months <br />) for batch waste discharged from the plant to travel the three miles through the 19-foot diameter tunnels to the diffuser nozzles. Additional mixing of the thermally buoyant effluent in the near field mixing zone assures that an equivalent overall 10 to 1 dilution occurs by the time the plume reaches the ocean surface.B.7-2 ODCM Rev. 24 The dose assessment models utilized in the ODCM are taken from NRC Regulatory Guide 1.109.The liquid pathway equations include a parameter (Mp) to account for the mixing ratio (reciprocal of the dilution factor) of effluents in the environment at the point of exposure.
Table 1, in Regulatory Guide 1.109, defines the point of exposure to be the location that is anticipated to be occupied during plant lifetime, or have potential land and water usage and food pathways as could actually exist during the term of plant operation.
For Seabrook, the potable water and land irrigation pathways do not exist since saltwater is used as the receiving water body for the circulating water discharge.
The three pathways that have been factored into the assessment models are shoreline exposures, ingestion of invertebrates, and fish ingestion.
With respect to shoreline exposures, both the mixing ratios of 0.1 and 0.025 are extremely conservative since the effluent plume which is discharged over one mile offshore never reaches the beach where this type of exposure could occur. Similarly, bottom dwelling invertebrates, either taken from mud flats near the shoreline or from the area of diffuser, are not exposed to the undiluted effluent plume. The shore area is beyond the reach of the surface plume of the discharge, and the design of the upward directed discharge nozzles along with the thermal buoyancy of the effluent, force the plume to quickly rise to the surface without affecting bottom organisms.
Consequentially, the only assumed exposure pathway which might be impacted by the near field plume of the circulating water discharge is finfish. However, the mixing ratio of 0.1 is very conservative because fish will avoid both the high exit velocity provided by the discharge nozzles and the high thermal temperature difference between the water discharged from the diffuser and the ambient water temperature in the near field. In addition, the dilution factor of 10 is achieved within 70 seconds of discharge and confined to a very small area, thus prohibiting any significant quantity of fish from reaching equilibrium conditions with radioactivity concentrations created in the water environment.
The mixing ratio of 0.025, which corresponds to the 1 degree thermal near field mixing zone, is a more realistic assessment of the dilution to which finfish might be exposed. However, even this dilution credit is conservative since it neglects the plant's operational design which discharges radioactivity by batch mode. Batch discharges are on the order of only a few hours in duration several times per week and, thus, the maximum discharge concentrations are not maintained in the environment long enough to allow fish to reach equilibrium uptake concentrations as assumed in the dose assessment modeling.
Not withstanding the above expected dilution credit afforded at the 1 degree isotherm, all Method 11 aquatic food pathway dose calculations shall conservatively assume credit for prompt dilution only with an Mp = 0.10. When dose impacts from the fish and invertebrate pathways are then added to the conservative dose impacts derived for shoreline exposures, the total calculated dose is very unlikely to have underestimated the exposure to any real individual.
The recommended value for dilution of 1.0 given in NUREG-0133 is a simplistic assumption provided so that a single model could be used with any plant design and physical discharge arrangement.
For plants that utilize a surface canal-type discharge structure where little entrainment mixing in the environment occurs, a dilution factor of 1.0 is a reasonable assumption.
However, in keeping with the guidance provided in Appendix I to IOCFR50, Seabrook has determine site-specific mixing ratios which factor in its plant design.B.7-3 ODCM Rev. 24 The transit time used for the aquatic food pathway was 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and for shoreline activity 0.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />. Table B.7-1 outlines the human consumption and use factors used in the analysis.
The resulting, site-specific, total body dose factors appear in Table B. 1-1 1. Appendix A provides an example of the development of a Method I liquid dose conversion factor for site-specific conditions at Seabrook.7.1.1 Dose to the Total Body For any liquid release, during any period, the increment in total body dose from radionuclide "i" is: ADtb = kQi DFLitb (mrem) 0 (Ci) m (7-1)where: DFLitb Site-specific total body dose factor (mrem/jtCi) for a liquid release. It is the highest of the four age groups. See Table B.1-11.Q Total activity (jtCi) released for radionuclide "i".k = 918/Fd (dimensionless);
where Fd is the average dilution flow of the Circulating Water System at the point of discharge from the multiport diffuser (in ft 3/sec).Method I is more conservative than Method II in the region of the Part A dose limits because the dose factors DFLitb used in Method I were chosen for the base case to be the highest of the four age groups (adult, teen, child and infant) for that radionuclide.
In effect each radionuclide is conservatively represented by its own critical age group.7.1.2 Dose to the Critical Organ The methods to calculate maximum organ dose parallel to the total body dose methods (see Part B, Section 7.1.1).For each radionuclide, a dose factor (mrem/jiCi) was determined for each of seven organs and four age groups. The largest of these was chosen to be the maximum organ dose factor (DFLimo)for that radionuclide.
DFLimo also includes the external dose contribution to the critical organ.For any liquid release, during any period, the increment in dose from radionuclide "i" to the maximum organ is: ADmo = k Q DFLimo (mrem) ( (j~i) (7-2)(mre) P .Ci B.7-4 ODCM Rev. 24 where: DFLimo = Site-specific maximum organ dose factor (mrem/gtCi) for a liquid release.

Method I may be used to show that the Part A Controls which limit total-body dose rate from noble gases released to the atmosphere (Part A Control C.7.1.1) has been met for the peak noble gas release rate.Method I was derived from general equation B-8 in Regulatory Guide 1.109 as follows: I)tb = I E+ 06 [X/Q ] DFBj (7-3)mrem/= r pCi ")(sec ( -tCi )(mrem-m 3 yr jiCi A m 3 A sec pCi-yr )where:[X/Q]y Maximum off-site receptor location long-term average gamma atmospheric dispersion factor.Q Release rate to the environment of noble gas "i' (IiCi/sec).

The sum of doses from both plant vent stack and ground level releases must be considered for determination of Technical Specification compliance.
All noble gases in Table B. 1-10 should be considered.
A Method II analysis could include the use of actual concurrent meteorology to assess the dose rates as the result of a specific release.7.2.2 Skin Dose Rate from Noble Gases This section serves: (1) to document the development of the Method I equation, (2) to provide background information to Method I users, and (3) to identify the general equations parameters and approaches to Method II-type dose rate assessments.
The methods to calculate skin dose rate parallel the total body dose rate methods in Part B, Section 7.2.1. Only the differences are presented here.Method I may be used to show that the Part A Controls which limit skin dose rate from noble gases released to the atmosphere (Part A Control C.7. 1.1) has been met for the peak noble gas release rate.The annual skin dose limit is 3,000 mrem (from NBS Handbook 69, Reference D, pages 5 and 6, is 30 rem/10). The factor of 10 reduction is to account for nonoccupational dose limits..B.7-8 ODCM Rev. 24 It is the skin dose commitment to the critical, or most limiting, off-site receptor assuming long-term site average meteorology and that the release rate reading remains constant over the entire year.Method I was derived from the general equation B-9 in Regulatory Guide 1.109 as follows: Ds = 1.11 Dar + 3.17 E+ 04 X QI[X/Q] DFSj (7-4)mrem =(mrem) (mrad)(pCi-yr)

7.2.3 Critical Organ Dose Rate from lodines, Tritium and Particulates With Half-Lives Greater Than Eight Days This section serves: (1) to document the development of the Method I equation, (2) to provide background information to Method I users, and (3) to identify the general equation's parameters and approached to Method II type dose rate assessments.
The methods to calculate skin dose rate parallel the total body dose rate methods in Part B, Section 7.2.1.Method I may be used to show that the Part A Controls which limit organ dose rate from iodines, tritium and radionuclides in particulate form with half lives greater than 8 days released to the atmosphere (Part A Control C.7. 1.1) has been met for the peak above-mentioned release rates.The annual organ dose limit is 1500 mrem (from NBS Handbook 69, Reference D, pages 5 and 6). It is evaluated by looking at the critical organ dose commitment to the most limiting off-site receptor assuming long-term site average meteorology.

These dose factors are used to determine accumulated doses over extended periods and have been calculated with the Shielding Factor (SF) for ground plane exposure set equal to 0.7, as referenced in Regulatory Guide 1.109. In the case of the dose rate conversion factors (DFG'ico(e) and DFG'ico(g)), the dose conversion factors from which they were derived were calculated with the Shielding Factor (SF) for ground plane exposure set equal to 1.0.For an off-site receptor and elevated effluent release point, the critical organ dose rate equation is: C. = *DFG co ) (3-5a)Dc(e)= i*D io(e))mrem= (,, Ci

Concurrent meteorology with time of release may also be used to assess compliance for a Method II calculation.
7.2.4 Gamma Dose to Air from Noble Gases This section serves: (1) to document the development and conservative nature of Method I equations to provide background information to Method I users, and (2) to identify the general equations, parameters and approaches to Method 11-type dose assessments.
Method I may be used to show that the Part A Control C.7'2.1 which limits off-site gamma air dose from gaseous effluents has been met for releases over appropriate periods. This Part A Control is based on the objective in 1OCFR50, Appendix I, Subsection B. 1, which limits the estimated gamma air dose in off-site unrestricted areas.NUREG/CR-2919 presents a methodology for determining atmospheric dispersion factors (CHI/Q values) for intermittent releases at user specified receptor locations (intermittent releases being defined as releases with durations between 1 and 8,760 hours0.0088 days <br />0.211 hours <br />0.00126 weeks <br />2.8918e-4 months <br />). The CHI/Q values for intermittent releases are determined by linearly interpolating (on a log-log basis) between an hourly 15-percentile CHI/Q value and an annual average CHI/Q value as a function of release duration.
This methodology has been adopted to produce a set of time-dependent atmospheric dispersion factors for Method I calculations.
For any noble gas release, in any period, the increment in dose is taken from Equations B-4 and B-5 of Regulatory Guide 1.109 with the added assumption that DYfinite = D7 [X/Q] 7 /[X/Q]: ADYe) = 3.17E+4 [X/Q]Y IQiDF(i (mrad) = (pCi- yr sec)(Ci) (mrad-m3 J (7-14)(Ci .pCi -yr where: 3.17E+04=

Method I may be used to show that Part A Control C.7.2.1, which limits off-site beta air dose from gaseous effluents, has been met for releases over appropriate periods. This Part A Control is based on the objective in 1OCFR50, Appendix I, Subsection B.1, which limits the estimated beta air dose in off-site unrestricted area locations.

Method I may be used to show that the Part A Controls which limit off-site organ dose from gases (C.7.3.1 and C.8.1.1) have been met for releases over the appropriate periods. Part A Control C.7.3.1 is based on the ALARA objectives in IOCFR50, Appendix I, Subsection II C.Part A Control C.8.1.1 is based on Environmental Standards for Uranium Fuel Cycle in 40CFR190, which applies to direct radiation as well as liquid and gaseous effluents.
These methods apply only to iodine, tritium, and particulates in gaseous effluent contribution.
Method I was developed such that "the actual exposure of an individual
... is unlikely to be substantially underestimated" (lOCFR50, Appendix I). The use below of a single "critical receptor" provides part of the conservative margin to the calculation of critical organ dose in Method I. Method H allows that actual individuals, associated with identifiable exposure pathways, be taken into account for any given release. In fact, Method I was based on a Method H analysis of a critical receptor assuming all pathways present. That analysis was called the"base case"; it was then reduced to form Method I. The base case, the method of reduction, and the assumptions and data used are presented below.B.7-16 ODCM Rev. 24 The steps performed in the Method I derivation follow. First, the dose impact to the critical receptor [in the form of dose factors DFGio for a unit activity release of each iodine, tritium, and particulate radionuclide with half lives greater than eight days to gaseous effluents was derived. Six exposure pathways (ground plane, inhalation, stored vegetables, leafy vegetables, milk, and meat ingestion) were assumed to exist at the site boundary (not over water or marsh areas) which exhibited the highest long-term X/Q. Doses were then calculated to six organs (bone, liver, kidney, lung, GI-LLI, and thyroid), as well as for the whole body and skin for four age groups (adult, teenager, child, and infant) due to the seven combined exposure pathways.
For each radionuclide, the highest dose per unit activity release for any organ (or whole body) and age group was then selected to become the Method I site-specific dose factors.The base case, or Method I analysis, uses the general equations methods, data, and assumptions in Regulatory Guide 1.109 (Equation C-2 for doses resulting from direct exposure to contaminated ground plane; Equation C-4 for doses associated with inhalation of all radionuclides to different organs of individuals of different age groups; and Equation C-13 for doses to organs of individuals in different age groups resulting from ingestion of radionuclides in produce, milk, meat, and leafy vegetables in Reference A). Tables B.7-2 and B.7-3 outline human consumption and environmental parameters used in the analysis.
It is conservatively assumed that the critical receptor lives at the "maximum off-site atmospheric dispersion factor location" as defined in Section 7.3.The resulting site-specific dose factors are for the maximum organ which combine the limiting age group with the highest dose factor for any organ with each nuclide. These critical organ, critical age dose factors are given in Table B. 1-12. Appendix A provides an example of the development of Method I gaseous dose conversion factor for site-specific conditions at Seabrook.For any iodine, tritium, and particulate gas release, during any period, the increment in dose from radionuclide "i" is: A Di,. = QiDFGico (7-16)where DFGico is the critical dose factor for radionuclide I"i and Qi is the activity of radionuclide

(3-8b)7.2.7 Special Receptor Gaseous Release Dose Calculations Part A Section 10.2 requires that the doses to individuals involved in recreational activities within the site boundary are to be determined and reported in the Annual Radioactive Effluent Release Report.The gaseous dose calculations for the special receptors parallel the bases of the gaseous dose rates and doses in Part B, Sections 7.2.1 through 7.2.5. Only the differences are presented here.The special receptor XQs are given in Table B.7-5.7.2.7.1 Total Body Dose Rate from Noble Gases Method I was derived from Regulatory Guide 1.109 as follows: I~tb 1E+ 06 [X/Q]yQ DFBi (7-3)General Equation (7-3) is then multiplied by an Occupancy Factor (OF) to account for the time an individual will be at the on-site receptor locations during the year. There are two special receptor locations on-site. The "Rocks" is a boat landing area which provides access to Browns River and Hampton Harbor. The Seabrook Station UFSAR, Chapter 2.1, indicates little boating activity in either Browns River or nearby Hunts Island Creek has been observed upon which to determine maximum or conservative usage factors for this on-site shoreline location.
As a result, a default value for shoreline activity as provided in Regulatory Guide 1.109, Table E-5, for maximum individuals was utilized for determining the "Rocks" occupancy factor. The 67 hour7.75463e-4 days <br />0.0186 hours <br />1.107804e-4 weeks <br />2.54935e-5 months <br />s/year corresponds to the usage factor for a teenager involved in shoreline recreation.
This is the highest usage factor of all four age groups listed in Regulatory Guide 1.109, and has been used in the ODCM to reflect the maximum usage level irrespective of age.Regulatory Guide 1.109 does not provide a maximum individual usage factor for activities similar to those which would be associated with the Seabrook Station Science & Nature Center.Therefore, the usage factor used in the ODCM for the Science & Nature Center reflects the observed usage patterns of visitors to the facility.
Individuals in the public who walk in to look at the exhibits on display and pick up available information stay approximately 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> each.Tour groups who schedule visits to the facility stay approximately 2.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />. For conservatism, it was assumed that an individual in a tour group would return five times in a year, and stay 2.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> on each visit.

The following exposure pathways to gaseous effluents listed in Regulatory Guide .1109 (Reference A) have been considered:
- 1. Direct exposure to contaminated air;2. Direct exposure to contaminated ground;3. Inhalation of air;4. Ingestion of vegetables;
- 5. Ingestion of goat's milk; and 6. Ingestion of meat.Part B, Section 7.3.1 details the selection of important off-site and on-site locations and receptors.
Part B, Section 7.3.2 describes the atmospheric model used to convert meteorological data into atmospheric dispersion factors. Part B, Section 7.3.3 presents the maximum atmospheric dispersion factors calculated at each of the off-site receptor locations.
7.3.1 Receptor Locations The most limiting site boundary location in which individuals are, or likely to be located as a place of residence was assumed to be the receptor for all the gaseous pathways considered.
This provides a conservative estimate of the dose to an individual from existing and potential gaseous pathways for the Method I analysis.This point is the west sector, 974 meters from the center of the reactor units for undepleted, depleted, and gamma X/Q calculations, and the northwest section, 914 meters for calculations with D/Q the dispersion parameter.
The site boundary in the NNE through SE sectors is located over tidal marsh (e.g., over water), and consequently are not used as locations for determining maximum off-site receptors (Reference NUREG 0133).Two other locations (on-site) were analyzed for direct ground plane exposure and inhalation only. They are the "Rocks" (recreational site) and the Education Center shown on Figure 5.1-1 of the Technical Specifications.
7.3.2 Seabrook Station Atmospheric Dispersion Model The time average atmospheric dispersion factors for use in both Method I and Method H1 are computed for routine releases using the AEOLUS-2 Computer Code (Reference B).B.7-30 ODCM Rev. 24 AEOLUS-2 produces the following average atmospheric dispersion factors for each location: 1. Undepleted X/Q dispersion factors for evaluating ground level concentrations of noble gases;2. Depleted X/Q dispersion factors for evaluating ground level concentrations of iodines and particulates;
- 3. Gamma X/Q dispersion factors for evaluating gamma dose rates from a sector averaged finite noble gas cloud (multiple energy undepleted source); and 4. D/Q deposition factors for evaluating dry deposition of elemental radioiodines and other particulates.
Gamma dose rate is calculated throughout this ODCM using the finite cloud model presented in"Meteorology and Atomic Energy -1968" (Reference E, Section 7-5.2.5).
That model is implemented through the definition of an effective gamma atmospheric dispersion factor, [X/QY](Reference B, Section 6), and the replacement of X/Q in infinite cloud dose equations by the[X/Qfl.7.3.3 Average Atmospheric Dispersion Factors for Receptors The calculation of Method I and Method II atmospheric diffusion factors (undepleted CHI/Q, depleted CHI/Q, D/Q, and gamma CHI/Q values) utilize a methodology generally consistent with US NRC Regulatory Guide 1.111 (Revision
- 1) criteria and the methodology for calculating routine release diffusion factors as represented by the XOQDOQ computer code (NUREG/CR-2919).
The primary vent stack is treated as a "mixed-mode" release, as defined in Regulatory Guide 1.111. Effluents are considered to be part-time ground level/part-time elevated releases depending on the ratio of the primary vent stack effluent exit velocity relative to the speed of the prevailing wind. All other release points (e.g., Turbine Building and Chemistry lab hoods) are considered ground-level releases.In addition, Regulatory Guide 1.111 discusses the concept that constant mean wind direction models like AEOLUS-2 do not describe spatial and temporal variations in airflow such as the recirculation of airflow which can occur during prolonged periods of atmospheric stagnation.
For sites near large bodies of water like Seabrook, the onset and decay of sea breezes can also result in airflow reversals and curved trajectories.
Consequently, Regulatory Guide 1.111 states that adjustments to constant mean wind direction model outputs may be necessary to account for such spatial and temporal variations in air flow trajectories.
Recirculation correction factors have been applied to the diffusion factors. The recirculation correction factors used are compatible to the "default open terrain" recirculation correction factors used by the XOQDOQ computer code.The relative deposition rates, D/Q values, were derived using the relative deposition rate curves presented in Regulatory Guide 1.111 (Revision 1). These curves provide estimates of deposition rates as a function of plume height, stability class, and plume travel distance.B.7-31 ODCM Rev. 24 Receptor Locations For ground-level releases, the downwind location of "The Rocks" (244m NE/ENE) and the Science & Nature Center (406m SW) were taken as the distance from the nearest point on the Unit 1 Administrative Building/Turbine Building complex. For the site boundary, the minimum distances from the nearest point on the Administration Building/Turbine Building complex to the site boundary within a 45-degree sector centered on the compass direction of interest as measured from UFSAR Figure 2.1-4A were used (with the exception that the NE-NE-ENE-E-ESE-SE site boundary sectors were not evaluated because of their over-water locations).
For primary vent stack releases, the distances from the Unit 1 primary vent stack to "The Rocks" (244m NE) and the Science & Nature Center (488m SW) as measured from a recent site aerial photograph were used. For the site boundary, the minimum distances from the Unit 1 primary vent stack to the site boundary within a 45-degree sector centered on the compass direction of interest as measured from UFSAR Figure 2.1-4A were used (with the exception that the NNE-NE-ENE-E-ESE-SE site boundary sectors were not evaluated because of their over-water locations).
Meteorological Data Bases For "The Rocks" and Science & Nature Center receptors, the diffusion factors represent six-year averages during the time period January 1980 through December 1983 and January 1987 through December 1988 (with the exception that, because of low data recovery, April 1979 and May 1979 were substituted for April 1980 and May 1980). For the site boundary receptors, both six-year average growing season (April through September) and year-round (January through December)diffusion factors were generated, with the higher of the two chosen to represent the site boundary.The meteorological diffusion factor used in the development of the ODCM Method I dose models are summarized on Tables B.7-4 through B.7-6.B.7-32 ODCM Rev. 24 Table B.7-4 Seabrook Station Lone-Term Averaue Dispersion Factors*Primary Vent Stack Dose Rate to Individual Dose to Air Dose to Critical Organ Total Skin Critical Gamma Beta Thyroid Body Organ X/Q depleted (sec 7.5E-07 -7.5E-07 X/Q undepleted (sec) 8.2E-07 8.2E-07 DQ _ 1.5E-08**

The liquid waste test tank monitor is placed upstream of the major source of dilution flow.The derivation of Equation 5-1 begins with the general equation for the response of a radiation monitor: R = Sh Ci S1i(8-1)(cps) (cps-ml)where: R Response of the monitor to radioactivity (cps).Sli Detector counting efficiency for radionuclide "i" (cps/(J.Ci/ml)).
Ci= Activity concentration of each gamma emitting radionuclide "i" in the mixture that the monitor has a response efficiency sufficient to detect (gCi/ml).The detector calibration procedure for the liquid waste test tank monitor at Seabrook Station establishes counting efficiency by use of a known calibration source standard and a linearity response check. Therefore, in Equation 8-1 one may substitute S 1 for Sli, where S, is the detector counting efficiency determined from the calibration procedure.
Therefore, Equation 8-1 becomes: R = Si Y Cy (8-2)(cps) =~ ~csm) (P4ci)B.8-1 ODCM Rev. 28 The ECL for a given radionuclide must not be exceeded at the point of discharge to the environment.
When a mixture of radionuclides is present, 10 CFR 20 specifies that the concentration (excluding dissolved and entrained noble gases) at the point of discharge shall be limited as follows: Cdi < 10 (8-3)ECLi where: Cdi = Activity concentration of radionuclide
'i" determined to be present in the mixture at the point of discharge to the environment (j.Ci/ml).
ECLi = Effluent concentration limit (ECL) for radionuclide "i" (except for dissolved and entrained noble gas) in ltCi/ml as specified in 10 CFR 20, Appendix B, Table 2.The limit for the sum of all noble gases in the waste discharge is 2E-04 pCi/ml.(See ODCM Appendix B for listing.)The activity concentration of radionuclide "i" at the point of discharge is related to the activity concentration of each radionuclide at the monitor as follows: C -Fd(C 1+/-c)( gpm i and with equivalence ofCi = (Cy 1 + Co3i), Equation 8-4 can be written as C =Fm Cdi F. Ci Fd where: Fm = Flow rate past monitor (gpm)Fd = Flow rate out of discharge tunnel (gpm)CJ3i = Activity concentration of non gamma emitting radionuclide "i" in the mixture at the monitor for which the monitor response is inefficient to detect (piCi/ml).
Ci = The activity concentration of each radionuclide
'i" in the waste stream. This includes both gamma and non gamma emitters, such as tritium.B.8-2 ODCM Rev. 28 Substituting the right half of Equation 8-4 for Cdi in Equation 8-3, and solving for Fd/Fm yields the dilution factor needed to complete Equation 8-3: DFmin < Fd >- Ca (8-5)Fm *1OECLi gpm) mi-pi)where: ECLi = Effluent concentration limit (ECL) for radionuclide "i" (except for dissolved and entrained noble gas) in piCi/ml as specified in 10 CFR 20, Appendix B, Table 2.For noble gases, a value of 2E-04 paCi/ml is used for the limit of the sum of noble gases in the waste stream.If Fd/Fm is less than DFmin, then the tank may not be discharged until either Fd or Fm or both are adjusted such that: DFmi. < Ed (8-5)Fm The maximum allowable discharge flow rate past the monitor can be found by setting Fm to Fmax and its equivalents, i.e: Fd Fmax --DFmin Usually Fd/Fm is greater than DFmin (i.e., there is more dilution than necessary to comply with Equation 8-3), but must be satisfied since the monitor can only detect the gamma emitting portion of the waste stream. The response of the liquid waste test tank monitor at the setpoint is therefore:
Rsetpoint

= fl X Fmax X SYS Cyi Fm where fi is equal to the fraction of the total concentration of ECL at the discharge point to the environment to be associated with the test tank effluent pathway, such that the sum of the fractions of the five liquid discharge pathways is equal to or less than one (f, + f 2 + f 3 + f 4 + f 5 < 1). The five monitored liquid effluent pathways are derived from: (fl) the Liquid Waste Test Tanks, (f 2) the Turbine Building Sump, (f 3) Steam Generator Blowdown, (fQ)Primary Component Cooling, and (f 5) Water Treatment Liquid Effluent (the Condensate Polishing System).The monitoring system is designed to incorporate the detector efficiency, SI, into its software.This results in an automatic readout in ptCi/ml or [iCi/cc for the monitor response.
Since the conversion for changing cps to tiCi/ml is inherently done by the system software, the monitor response setpoint can be calculated in terms of the total waste test tank activity concentration in jtCi/ml determined by the laboratory analysis.
Therefore, the setpoint calculation for the liquid waste test tank is: Rsetpoint
= f, x Fd x Y- Cyj (5-1)F. x DFmin ml ml All liquid effluent pathway monitors are similar to the Liquid Waste Test Tank Monitor in design and function as described above for ensuring the plant site's effluent concentration limits are not exceeded in combination with each other.B.8-4 ODCM Rev. 28 8.2 Basis for the Plant Vent Wide Range Gas Monitor Setpoints The setpoints of the plant vent wide range gas monitors must ensure that Part A Control C.7. 1.1 .a is not exceeded.
Part B, Sections 3.4 and 3.5 show that Equations 3-3 and 3-4 are acceptable methods for determining compliance with that Part A Control. Which equation (i.e., dose to total body or skin) is more limiting depends on the noble gas mixture. For the limiting setpoint case, the gas mixture associated with the fuel gap activity at time of shutdown (UFSAR Table 15.7-20) indicates that the total body dose rate to the maximum offsite receptor is the limiting dose rate type. The derivations of Equations 5-5 and 5-6 begin with the general equation for the response R of a radiation monitor: R = ISgi Cmi (8-7)i (cpm) = 3cpm-cm3 where: R = Response of the instrument (cpm)Sgi Detector counting efficiency for noble gas "i" (cpm/(gCi/cm 3))Cmi = Activity concentration of noble gas "i" in the mixture at the noble gas activity monitor (gCi/cm 3)Cmi, the activity concentration of noble gas "i" at the noble gas activity monitor, may be expressed in terms of Qi by dividing by F, the appropriate flow rate. In the case of the plant vent noble gas activity monitors the appropriate flow rate is the plant vent flow rate..1 Cmi = Qi -F (8-8)F= (sci) (cm3s where:= The relative release rate of noble gas "i" identified or postulated to be in the mixture.F = Appropriate flow rate (cm 3/sec)Substituting the right half of Equation 8-8 into Equation 8-7 for Cmi yields: R = ESgi j , 1 (8-9)i F/cpm-_cm3 13.8-5 ODCM Rev. 28 As in the case before, for the liquid waste test tank monitor, the plant vent wide range gas monitor establishes the detector counting efficiency by use of a calibration source. Therefore, Sg can be substituted for Sgi in Equation 8-9, where Sg is the detector counting efficiency determined from the calibration procedure.
Therefore, Equation 8-9 becomes: R= Sg 1 (8-10)F i (cpm) = cPm-cm3- Csec 3 sc The total body dose rate due to noble gases is determined with Equation 3-3a: DItb(e) = 0.85 * (i

By setting DhkJ equal to 3,000 mrem/yr and substituting DF'c for DF'i in Equation 3-4 one may solve for ZQi at the limiting skin noble gas dose rate: 3,000 (8-15)i DF'c (sAciD (mrem)( pCi-yr sec yr mrem -sec)Substituting this result for Oin Equation 8-10 yields Rskin, the response of the monitor at the limiting noble gas skin dose rate: Rskin = 3,000 Sg 1 F DF'c (cpm) (mrem] cpm -cm'/ sec' p. i, C-yr /(8-16)\yr ' .,Ci ).cm 3J mrem -sec)As with the liquid monitoring system, the gaseous monitoring system is also designed to incorporate the detector efficiency, Sg, into its software.
The monitor also converts the response output to a release rate (p.Ci/sec) by using a real time stack flow rate measurement input.Therefore, multiplying by the main plant vent flow rate measurement (F), the Equations 8-13 and 8-16 become: Rtb(e) 588 (5-5)DFBc ([tCi) = (torero -RtCi -m3.( pCi -yr 3 sec yr -pCi -sec mrem -m R skin(e) 3,000 (5-6)DF'(lICi) = (mrem) ( Ci- yr.)sec yr mrem -sec These equations assume that the main plant vent is the only release point contributing to the determination of limiting offsite dose rate. The Control dose rate limits (500 mrem/yr and 3000 mrem/yr for total body and skin, respectively) apply to combination of all release points to the limiting offsite receptor.
Administrative fractions (f) should be applied to main plant vent setpoint calculation as a multiplier, and any other release points, such that the summation of all fractions is less than or equal to 1. This provides for the combined impact of all release points to ensure that selected setpoints alarm at or before the site dose rate limits is exceeded.B.8-9 ODCM Rev. 28 8.3 Basis for PCCW Head Tank Rate-of-Change Alarm Setpoint The PCCW head tank rate-of-change alarm will work in conjunction with the PCCW radiation monitor to alert the operator in the Main Control Room of a leak to the Service Water System from the PCCW System. For the rate-of-change alarm, a setpoint based on detection of an activity level of 10-8 jiCi/cc in the discharge of the Service Water System has been selected.
This activity level was chosen because it is the minimum detectable level of a service water monitor if such a monitor were installed.
The use of rate-of-change alarm with information obtained from the liquid sampling and analysis commitments described in Table A.6.1-1 of Part A ensure that potential releases from the Service Water System are known. Sampling and analysis requirements for the Service Water System extend over various operating ranges with increased sampling and analysis at times when leakage from the PCCW to the service water is occurring and/or the activity level in the PCCW is high.B.8-10 ODCM Rev. 28 8.4 Basis for Waste Gas Processing System Monitors (RM-6504 and RM-6503)The maximum allowable setpoint for the waste gas system monitors (response in PCi/cm 3) can be determined by equating the limiting off-site noble gas dose rate from the plant vent to the total body or skin dose rate limits of Part A Control C.7.1.1 .a, assuming that all the activity detected by the vent wide-range gas monitors is due to waste gas system discharges.
By evaluating the noble gas radionuclide with the most limiting dose factor as given on Table B. 1-10, a conservative activity release rate from the plant vent for both whole body and skin dose rate conditions can be calculated.
From Table B.1-10, Kr-89 is seen to be the most restrictive individual noble gas if it were present in the effluent discharge.
Applying plant vent setpoint equation 5-5 for the whole body, and equation 5-6 for the skin, the maximum allowable plant vent stack release rate can be calculated as follows: Rtb 588 1/DFB, (5-5)where: Rtb = plant vent maximum release rate (liCi/sec) based on the whole body does rate limit of 500 mrem/yr DFBc = 1.66E-02 (mrem-m 3/pCi-yr), whole body dose factor for Kr-89 588 = conversion factor (mrem-gtCi-m 3/yr-pCi-sec)
Therefore:
Rtb = 588 1/1.66E-02
= 35,421 [tCi/sec maximum release rate at plant vent Next, the skin dose rate limit is evaluated from equation 5-6 in a similar fashion as follows: Rskin 3000 1/DF'c (5-6)where: Rskin = plant vent maximum release rate (jtCi/sec) based on skin dose rate limit of 3000 mrem/yr.DF'c = 2.45E-02 mrem-sec/jtCi-yr skin dose factor for Kr-89 3000 = Site boundary skin dose rate limit (mrem/yr)B.8-11 ODCM Rev. 28 therefore:
Rskin = 3000 (mrem/yr) 1/2.45E-02(mrem-sec/liCi-yr)
= 122,449 [tCi/sec from the plant vent Comparing the release rate limit for the whole body to that for the skin (i.e., 35,421 gCi/sec vs 122,449 [iCi/sec, respectively) it is determined that the release rate for the whole body is limiting.Next, to get the maximum plant vent release rate from the waste gas system discharge, equate the plant vent maximum release rate limit for the whole body equal to the waste gas system activity concentration times its flow rate to the plant vent, i.e.: Rtb = 35,421(ltCi/sec)
= Rwg(g.Ci/cm
- 3) F wg(Cm 3/sec)or solving for Rwg: Rwg(gtCi/cm
- 3) 35,421(gtCi/sec)
/ Fwg(Cm 3/sec)where: Rwg = maximum concentration (setpoint limit) at the waste gas system monitors Fwg = waste gas design flow of 566.4 cm 3/sec (1.2 cfm)therefore:
Rwg(ptCi/cm
- 3) 35,421(jtCi/sec)
/ 566.4(cm 3/sec)62.5 ltCi/cm 3 This represents the maximum waste gas discharge concentration which would equal the site boundary whole body dose rate limit for plant vent releases.
Administrative controls may set alert alarm and high alarm (waste gas isolation) setpoints on the waste gas monitors as some multiple of expected activity concentration, such as 1.5 and 2 times, respectively, as long as the maximum setpoint does not exceed 62.5 pCi/cm 3.This provides operational controls to be exercised before any waste gas discharges could equate to the Part A Control C.7. 1.1 .a.The primary process monitor noted in Part A Control C.5.2 is RM-6504, which is downstream of the waste gas discharge compressor at the end of the process system. Monitor RM-6503 is on the inlet side of the compressor downstream of the charcoal delay beds, and is considered as an alternate monitor if RM-6504 is inoperable.
For the purpose of setting the maximum discharge setpoint, RM-6503 is treated the same as RM-6504, which assumes no additional source reduction before discharge to the plant vent.B.8-12 ODCM Rev. 28 8.5 Basis for the Main Condenser Air Evacuation Monitor Setpoint (RM-6505)The maximum allowable setpoint for the main condenser air evacuation monitor must be evaluated for two modes of operation.
For normal operations the monitor is responding to a low flow rate that is typically released through the plant vent stack. During start-up (hogging mode), the monitor response must be related to a high flow rate that is being released from the turbine building which is considered a ground level release. In both instances, the setpoint can be determined by equating the limiting off-site noble gas dose rate from the release point to the total body or skin dose rates of Part A Control C.7.1.1 .a. The most restrictive noble gas mixture has been found to be represented by the noble gases associated with the fuel gap activity at the time of plant shutdown.
This mixture is listed on UFSAR Table 15.7-20, and provides a limiting setpoint calculation that bounds other potential or observed offgas mix conditions.
In addition to monitoring the main condenser air, the air evacuation monitor response is also used as an indicator for Turbine Gland Seal Condenser exhaust. Since this is a potential release pathway during both the normal and the hogging modes of operation, the impact is considered in the setpoint calculations.
8.5.1 Limiting Example for the Air Evacuation Monitor Setpoint During Normal Operations During normal power operation, the maximum allowable setpoint for the air evacuation monitor is determined by applying plant vent setpoint equation 8-13 for the total body, and equation 8-16 for the skin. Therefore, the maximum allowable stack release rate can be calculated as follows: Rtb(e) = (588) (Sg) (I/F) (8-13)(cpm) = (mrem-[tCi-m 3/yr-pCi-sec) (cpm-cm 3/4.Ci) (sec/cm 3)(pCi-yr/mrem-m 3)where: Rtb(e) = count rate (cpm) for the plant vent maximum release rate based on the total body dose rate limit of 500-mrem/yr 588 = conversion factor (mrem-[tCi-m 3/yr-pCi-sec)
Sg = the detector response efficiency (cpm-cm 3/[tCi) as determined from monitor calibration.
For the air evacuation monitor, a typical value is 1.87E+08 cpm-cm 3/4iCi.F = release flow rate. During normal operations, a typical flow value ranges from 10 to 50 cfm (2.36E+04 cc/sec maximum) for the air evacuation pathway.DFBc = the composite total body dose factor, (mrem-m 3/pCi-yr).
For different gas mixes, the composite can be found from: DFBC = Y, OQDFBli 0 / 1 (5-7)i i DFBc for the limiting gas mixture is 4.86E-03 mrem-m 3/pCi-yr (See Section 5.2.1.2)B.8-13 ODCM Rev. 28 Therefore, Rtb(e) = 588 1.87E+08 (1/2.36E+04)
(1/4.86E-03)
= 9.59E+08 cpm detector count rate for a maximum release rate at the plant vent based on the total body dose rate.Next, the off-site skin dose rate limit is evaluated from equation 8-16 in a similar fashion as follows: Rskin(e) = 3000 Sg (I/F) (1/DF'c) (8-16)(cpm) = (mrem/yr) (cpm-cm 3/Ci) (sec/cm 3) (gCi-yr/mrem-sec) where: Rskin(e) = count rate (cpm) for a plant vent maximum release rate based on the skin dose rate limit of 3000 mrem/yr DF'c = the elevated release skin dose factor for the limiting noble gas mix associated with fuel gap activity at shutdown is calculated in the example provided in Section 5.2.1.2, and is equal to 6.80E-03 (mrem-sec/pCi-yr).
Therefore, Rskin(e) = 3000 1.87E+08 (1/2.36E+04)
(1/6.80E-03)
= 3.50E+09 cpm detector count rate for a maximum release rate at the plant vent based on the skin dose rate.Comparing the release rate limit for the total body to that of the skin (i.e., 9.59E+08 cpm versus 3.50E+09 cpm, respectively) it is determined that the release rate for the total body is limiting in this case.Since during normal operations the Turbine Gland Seal Condenser exhaust has the potential to be a minor additional contribution to the total site release, the effective contribution from the main condenser exhaust must be limited to some fraction of the calculated value. The contribution from the Turbine Gland Seal Condenser exhaust is expected to be minor because this system handles only 670 lbs/hour of steam which is a very small fraction of the 1.5E+07 lbs/hour of secondary side steam that the main condenser handles. Therefore, the maximum alarm is set at 6.71 E+08 cpm, which is 70% of the calculated value, to ensure that the contribution of the two does not exceed the dose rate limit of Part A Control C.7.1.1.a.
During normal operations, this would represent the maximum allowable count rate on the air evacuation monitor that would equate to the site boundary total body dose rate limit or less.B.8-14 ODCM Rev. 28 8.5.2 Example for the Air Evacuation Monitor Setpoint During Startup (Hogging Mode)During startup (hogging mode), the determination of the air evacuation setpoint must take into account a larger air flow rate that is also released as a ground level effluent.
The flow rate must also include the contribution from the Turbine Gland Seal Condenser exhaust, which is a potential release pathway which the air evacuation monitor response must also take into account.For ground releases, the general equation 8-10 is used to represent the monitor count rate.R = (Sg) (1/F) ZQ 1 i (8-10)(cpm) = (cpm-cm3/4iCi) (sec/cm 3) (jtCi/sec) where: R = detector count rate (cpm)Sg = the detector efficiency (cpm-cm 3/4iCi)F = release flow rate (cm 3/sec)= the release rate of noble gas "i" in the mixture, for each noble gas listed in Table B. 1-10.For a ground release, the off-site total body dose rate is based on: Itb(g) = 3.4 Y (Q DFBi) (3-3b)i A composite total body dose factor, DFBc can be defined such that: DFBc YQi = Z(QDFBi) (8-11)i i B.8-15 ODCM Rev. 28 By substituting 8-11 into 3-3b and rearranging to solve for 1 the following equation is obtained:-0 i = (,b~tg / 3.4) (1/DEB,;)By inserting-a limiting value of 500 mrem/yr as btb(g) this simplifies to: Y0 = 147 (1/DFBJ)i Insertion of this equation into equation 8-10 yields: Rtb(g) = 147 S(g) (1/F) (1/DFBJ)(cpm) -(mrem-jiCi-m 3/yr-pCi-sec) (cpm-cm 3/g1Ci) (sec/cm 3) (pCi-yr/mrem-m 3)where: Rtb(g) = count rate (cpm) for the maximum ground release rate based on the total body dose rate limit of 500 mrem/yr.147 = conversion factor (mrem-[tCi-m 3/yr-pCi-sec)
Sg = the detector response efficiency for the air evacuation monitor (a typical value of 1.87E+08 cpm-cm3/[LCi is applied in this example).F release flow rate. During the hogging mode of operation, a value of 4.72E+06 cm 3/sec (10,000 cfm) is assumed. This represents the hogging flow that is discharged to the Turbine Building roof via the air evacuation monitor. An additional 1800 cfm is discharged from the Gland Seal Condenser exhaust directly to the Turbine Building roof without passing via the air evacuation monitor. To account for this unmonitored flow, an administrative fraction (fgland) is applied to the setpoint calculation to ensure that the monitor would alarm before the dose rate limit for the combined release would be exceeded.
One approach for determining a conservative fraction is to assume that the radioactivity concentration in the gland seal exhaust is equal to the main condenser offgas, even though the steam flow to the gland seal system is a very small fraction of the steam flow to the main condenser.
Then the ratio of the Gland Seal Condenser exhaust flow to the total flow of hogging discharge and gland seal condenser provides for the relative flow of both sources. For the stated conditions, the unmonitored flow is about 15 % of the total (as additional conservatism, this could be doubled to 30% for the relative proportion assumed to be contributed by the unmonitored pathway).
Therefore, fgland = 1-0.3, or 0.7 as the fraction applied to the air evacuation monitor setpoint.
An additional fraction (fg) is also applied to account for the potential offsite dose rate contribution from this total ground source vs the plant main vent (fg< I -fQ). The split for this illustration is set at 0.3 for ground sources and 0.7 for the plant vent.B.8-16 ODCM Rev. 28 DFBc = Composite total body dose factor which weights the combination of total body dose factors (from ODCM Table B. l-10) of each radionuclide assumed to be in the gas mix in accordance with the fraction that it makes up of the total release. For the limiting noble gas mix associated with fuel gap activity at shutdown (see example calculation provided in Section 5.2.1.2), the value is equal to 4.86E-03 (mrem-m 3/pCi-yr).In addition, two administrative fractions are applied to the general calculation to account for other release contributions to the site dose that do not go by the air evacuation monitor. The first (fg) is the fraction of the site boundary total body dose rate limit to be administratively assigned to monitored ground level releases (for this illustration
= 0.3) such that the combination of the plant vent fraction (fQ) and ground fraction (fg) is less than or equal to I (fg < 1 -fQ). The second release reduction factor (fgland) is administratively assigned to account for potential unmonitored contributions from the Turbine Gland Seal Condenser exhaust (for this illustration
= 0.7) which discharges to the Turbine Building roof without going past the air evacuation monitor Therefore:
Rtb(g) = (147) (1.87E+08)
(1/4.72E+06)
(1/4.86E-03)
(0.3) (0.7)= 2.52E+05 cpm detector count rate for a maximum ground release rate based on the total body dose rate.Next, the off-site skin dose rate limit for a ground release is evaluated from equation 3-4b in a similar fashion as follows: Dskin(g) i E(Q jDFi(g)) (3-4b)A composite skin dose factor, DF'c(g) can be defined such that: DF'c(g) 0i : 1(QDFi~g)
(8-17)By substituting 8-17 into 3-4b and rearranging to solve for ZQ 1 the following equation is obtained: Yj = DSkin(g)0 (I/DF'(g))
i By inserting a limiting value of 3000 mrem/yr as Dskin(g) this simplifies to: Yi 3000 (l/DF'c(g))
Insertion of this equation into equation 8-10 yields: Rskin(g) = 3000 Sg (1/F) (1/DF'c(g))(cpm) = (mrem/yr) (cpm-cm3/4tCi) (sec/cm 3) (ýtCi-yr/mrem-sec)

For the limiting noble gas mix associated with fuel gap activity at shutdown (see example calculation provided in Section 5.2.1.2), the value is equal to 6.80E-03 (mrem-sec/gCi-yr).
As with the whole body dose rate above, the same two administrative fractions, fg and fgland are also applied to the skin dose rate response.Therefore:
Rskin(g) = (3000) (1.87E+08)
(1/4.72E+06)
(1/6.80E-03)
(0.3) (0.7)3.67E+06 cpm detector count rate for a maximum ground release rate based on the skin dose rate.Comparing the release rate limit for the total body to that of the skin (i.e., 2.52E+05 cpm versus 3.67E+06 cpm, respectively) it is determined that the release rate for the total body is limiting in this case.B.8-18 ODCM Rev. 28 REFERENCES A.

R-1 ODCM Rev. 21 APPENDIX A DOSE CONVERSION FACTORS A-1 ODCM Rev. 21 APPENDIX A METHOD I DOSE CONVERSION FACTORS I. LIQUID PATHWAYS -SEABROOK SITE SPECIFIC DCF'S The models used to assess doses resulting from effluents into liquids is derived from Appendix A of Reg. Guide 1.109. Since Seabrook is a salt water site, the assumed pathways of exposure taken from Reg Guide 1.109 are Aquatic foods -fish; Aquatic foods -invertebrates; and dose from shoreline deposits (direct dose). No drinking water or irrigation pathways exist because of the salt water environment.
In addition, exposures resulting from boating and swimming activities have been included for key radionuclides even though Reg. Guide 1.109 identifies these pathways as not contributing any significant contribution to the total dose, and therefore does not provide dose equations for them. For completeness, the swimming and boating pathways have been included using the dose models from the HERMES code (HEDL-TME-71-168, Dec. 1971) section G, Water Immersion.
The Method I dose conversion factors are derived by calculating the dose impact to individuals via the site specific pathways for a unit activity release (1 curie per nuclide).
For each pathway, doses by radionuclide are calculated for each of the 7 organs (including whole body) for each of the four age groups (adult, teen, child, and infant). The Method I dose factor for each nuclide is then selected by taking the highest factor for any organ in any of the age groups for all the exposure pathways combined.The list of dose factors in the ODCM then represents a combination of different limiting organs and age groups which, when used to calculate a dose impact from a mix of radionuclides released in liquid effluents, gives a conservative dose since it combines the exposure to different organs and age groups as if there was a single critical organ-age group.As an example of how the liquid dose conversion factors are developed, the following calculation for Co-60 is shown. The critical organ/age group is selected based on the full assessment of all organs and age groups.Factor for fish Ingestion:

Next, the dose from invertebrates to the adult GI-LLI is given by the same general equation but with the following variables changed: Uap := 5 kg/yr usage factor Bip 1000 1/kg bioaccumulation factor all other variables the same as above therefore the dose from invertebrates is (mrem/yr):

For the above equation, the site specific variables for an adult exposure to a 1 curie per year release of Co-60 are: Uap := 334 hrs/year usage factor used for assumed shoreline activities at Seabrook.MP 0.1 mixing ratio for near field dilution provided by the submerged multiport diffuser and assume to be extended to the beach continuously.

e-'*tp* [1- e-**tb]= 0.0573 5 F Direct dose due to Swimming: The dose due to immersion in water (swimming) is taken from the HERMES computer code.The original ODCM calculation was based on some preliminary dilution assumptions which gave A-4 ODCM Rev. 21 a near field prompt dilution factor for the multiport diffuser of 8. For single unit operation with both service water and circulating water flow (412,000 gpm), a value of 10 is more realistic.
This surface area of the plume is restricted to a small area over the diffuser and does not touch the shoreline approx. 1 mile away. Since the over all impact from swimming is small when compared to the other exposure pathways, the original conservatism on dilution are kept here.The dose from swimming is given by the following equation: 1.0*1012 * , Qi
- DFim 6 (mrem/yr)Fa Where: UP 45 hrs/yr, usage factor for swimming for maximum age group (teen) from HERMES.Fa := 6.56*1011 liters/yr, estimated annual dilution effluent flow in multiport diffuser Qi 1.0 Curies/yr, assumed release rate of nuclide i.DFim := 4.6*106 mrem-liters per hrs-pCi, dose factor for Co-60 for water immersion taken from HERMES.1.0* 1012 constant for pCi/Ci Therefore the swimming dose for a 1 curie release of Co-60 is (mrem/yr):
1.0* 1012
- Up* MP
- Q *DFim = 3.155* 10-57 Fa As can be seen, the contribution of the swimming dose is only about one 30000ths of the total of the RG 1.109 pathways, and can be ignored in the case of Co-60. Similarly, the boating dose as given in HERMES is taken as half of the swimming dose, (and corrected for change in usage assumptions).
The resulting dose is found to be less than the swimming dose and can also therefore be discounted in this case.Total liquid Pathway dose: The sum of the above liquid pathway doses can now be added to give the total maximum individual dose to the critical organ (adult-GI-LLI) for Co-60. This gives: 0.0103 + 0.0245 + 0.0573 = 0.0921 mrem/yr A-5 ODCM Rev. 21 Since the internal doses given by the RG- 1.109 methods actually are 50 yr dose commitments resulting from one year exposure to the quantity of activity assumed to be released into the water, and the direct dose represents the dose received for the period assumed to be exposed to the pathway, and the activity release was taken as a unit quantity (i.e. Q = 1 Ci), the above total liquid pathway dose can be stated as site specific committed dose factor in mrem/Ci released.For Method I in the ODCM, the critical organ dose factor is seen to be 0.0921 mrem/Ci, as shown above. The value reported on Table B.I-1 1 (9.22 E-08 mrem/jICi) was generated by a computational routine which gives rise to the round-off difference between it and the above example. The whole body site specific dose factor for the ODCM was calculated in the same way treating the whole body as a separate organ.A-6 ODCM Rev. 21 II. GASEOUS PATHWAYS -SEABROOK SITE SPECIFIC DCF'S The models used to assess doses resulting from gaseous effluents in the form of iodines, tritium, and particulates are derived from Appendix C of Reg. Guide 1.109. For Seabrook, it is assumed that at the off site location which exhibits minimum atmospheric dilution for plant releases the following exposure pathways exist: inhalation, ground plane, ingestion of goats milk, meat, stored vegetables, and leafy vegetables.
The Method I dose and dose rate factors are derived by calculating the dose impact to all age group individuals via the site specific pathways for a unit activity release (1 curie per nuclide).
For each pathway, doses by nuclide are calculated for each of 7 organs (including the whole body) for each of the 4 age groups. The Method I dose factor for each nuclide is then selected by taking the highest factor for any organ in any of the age groups for all exposure pathways combined.
The list of dose factors in the ODCM then represents a combination of different limiting organs and age groups which, when used to calculate the dose impact from a mix of radionuclides released into the atmosphere, gives a conservative dose since it combines the exposure to different organs and age groups as if they were for all the same critical organ-age group.As an example of how the gaseous particulate dose factors are developed, the following calculation for Mn-54 is shown. The critical organ/age group for Mn-54 was selected based on a full assessment of all organ and age group combinations.
For elevated releases from the plant vent stack to the maximum site boundary (max. dose point due to meteorology), the critical organ and age group for Mn-54 was determined to be the GI-LLI for the adult.PART A: INHALATION DOSE CONTRIBUTION The general equations for inhalation doses in RG 1.109 are eq.

As an initial step to determining the dose contribution from ingestion of milk, meat, stored vegetables, and leafy vegetables, we must first calculate the radionuclide concentration in forage, produce, and leafy vegetables resulting from atmospheric tranfers of the activity to the surface of the vegetation and onto the soil for root uptake. For all radioiodines and particulate nuclides (except tritium and C- 14), the concentration of nuclide i in and on the vegetation at a point of interest can be calculated using R.G.1.109 equations C-5 and C-6, which combined gives: 1.14*10 8* L

- 1. 0 INTRODUCTION Software testing as described in Reference (1] has been conducted for the Seabrook Station version of the Canberra Effluent Management System (EMS). The results and conclusions are presented in this report.1.1 Background Canberra Industries Inc. developed the EMS software to assist nuclear power plant personnel track effluent emissions and perform associated dose calculations.
North Atlantic Energy Service Corporation purchased a Seabrook-specific version the Canberra EMS software which must meet specific requirements and incorporate site-specific information provided in the Offsite Dose Calculation Manual (ODCM) [2]. Software testing was conducted to provide assurances that the Seabrook EMS program produces results which are consistent with current ODCM assumptions and methods. All executions of the EKS program were performed at Seabrook Station on the target software.
All executions of ODCM Method II were conducted at Yankee Atomic Electric Company in Bolton, Massachusetts.
1.2 Acceptance Criteria The operability of the EMS software will be accepted if Mi) information contained in the EMS data files is consistent with the ODCH, (ii) test results from the EMS program are consistent with results from ODCM methods, (iii)Technical Specifications requirements are met by the EMS software, and (iv) the EMS software meets design specifications.
Final user (Seabrook) acceptance is contingent on Seabrook approval of verification testing results and criteria established by user needs.1 2.0
SUMMARY
OF OBSERVATIONS The EMS software testing included (i) identifying appropriate meteorological set up data, (ii) review of dose and dose rate conversion factor development, (iii) assessments for liquid releases, and (iv) assessments for gaseous releases.
ODCM Method I was used initially to confirm dose results from the EMS program. However, the simplified nature of ODCM Method I made it difficult to change the values of various parameters or obtain meaningful comparisons (other than "bottom line" comparisons).
The more adaptable ODCH method, Method II, was then used to confirm EMS doses. Observations made during the software testing are summarized below.2.1 EMS Dose and Dose Rate Conversion Factors The EMS software uses precalculated conversion factors which are contained in a data file. The dose conversion factors for both liquid and gaseous effluent releases were developed for four age groups (adult, teen, child and infant), and for specific organs (bone, liver,total body, kidney, lung, GI tract and skin).The liquid release dose conversion factors in the EMS program are the summation of the components for water recreation and ingestion of aquatic foods. The gaseous release dose conversion factors are exposure pathway-specific (e.g., inhalation, ground plane, milk ingestion, etc.).Dose conversion factors are provided in the EMS program for all exposure pathways addressed in the ODCM. The development of all dose conversion factors in the EMS program followed the pathway-specific equations in the Effluent Management System Technical Reference Manual (3]. The EMS conversion factors for several radionuclides were examined to determined that the development process was consistent to the Technical Reference Manual and the ODCM.2 2.1.1 Liquid Release Dose Conversion Factors*Although the individual components for the ingestion of aquatic foods were found to be consistent with the ODCM, a discrepancy was discovered in the water recreation component.
The mixing ratio for shoreline activity used in the development of the EMS dose factors is equal to 0.025. While this value is inconsistent with ODCH Method I (which employs a mixing ratio of 0.1), it is consistent with ODCM Method II. It is identified as a discrepancy because it is unclear which set of ODCH assumptions (those for Method I or those for Method II)the EMS program is expected to adopt.2.1.2 Gaseous Release Dose Conversion Factors The EMS program uses dose conversion factors from Regulatory Guide 1.109 for assessment of noble gas releases.
The dose factors in the EMS program were verified against and found to be consistent with Table B-i of Regulatory Guide 1.109 [4].The development methods for the other gaseous dose factors (i.e., for inhalation, ground plane, milk ingestion, meat ingestion, and ingestion of vegetables) were reviewed against applicable equations in the Technical Reference Manual and information in the ODCM. It is noted that the dose factors for ingestion of milk and meat are based on the fraction of year that animals are allowed to graze on pasture land (Fp) equal to 1-0. This is not consistent with the ODCM which calls for the use of an Pp value equal to 0.5.The dose conversion factors in the EMS program for gaseous releases incorporate a shielding factor (SF) equal to 1.0. The EMS program is designed with a way of changing the value of SF (via use of the Options Table), but the factor is applied uniformly to both doses and dose rates. In contrast, the ODCM calls for the use of different values for SF in the calculations for doses and 3 dose rates.2.2 Liquid Release Testing Dose estimates from the EMS program for hypothetical liquid effluent discharges (containing single nuclide and radionuclide mixtures) are nearly identical to results from ODCM Method. II when input data are based on the same mixing ratio value, indicating that the calculation method used in the EMS program is consistent with the ODCM. Additionally, the EMS routine(s) responsible for liquid effluent concentrations comparisons to MPC values and monitor set point determinations was observed to be operating properly.2.3 Caseous Release Testing The agreement between estimates for total body dose rates, skin dose rates, and air (gamma and beta) doses due to emission of noble gases from the ODCH methods and the EMS program is excellent, indicating that the EMS calculation method is consistent with the ODCM.There is also excellent agreement between inhalation doses from the EMS program and ODCK Method II indicating that, for the inhalation pathway, the calculational method and assumptions in the EMS program are consistent with those in the ODCM. The evaluation of the dose estimates via inhalation pathway included both long and short release durations for an elevated (mixed mode) and a ground level release point. The excellent agreement between the EMS and ODCX Method II also confirms that the release duration adjustment term, t-a, is applied properly in the EMS program. However, an incorrect receptor location was reported on the EMS printout in the tests (D-2c and D-2d) in which the Plant Vent was changed to be recognized as a ground level release- point.Also noted during testing was that the EMS routine(s) responsible for calculating effluent concentration-to-MPC ratios and radionuclide release rates 4 appears to be operating properly for gaseous'releases.
The EMS program incorporates the assumption that the fraction of elemental iodine is equal to 1.0 (consistent with NUREG-0133
[5]). In contrast, the fraction of elemental iodine is assumed equal to 0.5 in the ODCM methods (consistent with Regulatory Guide 1.109). Consequently, the EMS program produces dose estimates due to radioiodine that are at least a factor of two greater than doses from the ODCM methods. This difference increases to about a factor of 4 when the current values for Fp and SF assumed in the EMS program and ODCK methods are used in the dose calculations.
The different assumptions for elemental iodine fractions should not present a problem because each program is based on NRC guidance:
the EMS is based on NUREG-0133, the ODCM methods are based on Regulatory Guide 1.109. The EMS program takes the more conservative approach for determining doses from radioiodine.
Making appropriate adjustments for Fp, SF, and the fraction of elemental iodine (when radioiodine input was used) and comparing results for organ doses due to 1131, H3, Co60 and Cs137 revealed that the calculational methods used in the EMS program are consistent with the ODCM for all exposure pathways (i.e..ground plane, inhalation, milk ingestion, meat ingestion, and vegetables ingestion).
Technical Specification 3.11.2.1 and the ODCM require the calculation of organ dose rates due to effluent discharges of 1131, 1133, H3 and particulates with a half-life greater than 8 days. However, in all test cases involving these types of nuclides, organ dose rate information did not appear on Page 4 of the EMS printout.
Instead, the message "No calculations performed
-check Sample &Receptors" appeared.
The EMS set up data and input were reviewed with no apparent error identified.
Since the test cases included Csl37, Co60, 1131, and*5 H3, the missing dose rate information was unexpected.
It is noted that organ dose rate information was provided on Page 4 of the E!1S printout during a demonstration of the EMS program prior to testing.0 3.0 TEST CONCLUSIONS Although the dose conversion factors are based on information which is not completely consistent with the assumptions in the ODCM, the calculational methods used to determine doses from liquid and gaseous effluent discharges are consistent with the ODCM methods.Other conclusions are: 1. As stated in Section 2.1.1, the development of the EMS liquid effluent dose factors is consistent with ODCM Method I1, but not with Method I due to the mixing ratio value. If the EMS program is intended to be a hybrid method, the dose factors are consistent with the ODCH and are acceptable.
On the other hand, if the EMS program is intended to provide automated ODCM Method I calculations, then the dose factor should be recalculated using a mixing ratio for shoreline activity equal to 0.1.2. Since the EMS program is not designed to support the use of two 0 shielding factors' (one for dose rates and one for doses), use of a shielding factor equal to 1.0 is acceptable with the understanding that, although the dose rates produced by the EMS program will be consistent with the ODCM, the doses from the EMS program will be based on a more conservative assumption than doses from the ODCM methods.3. Under the normal ODCM assumption for elemental iodine, the results from the EMS program will be at least a factor of two greater than results from the ODCM methods. The different assumptions regarding the elemental iodine fraction do not present a problem because each program is based on NRC guidance:
the EMS program is based on NlUREG-0133, and the ODCM is based on Regulatory Guide 1.109. Of the two methods, the EMS program takes the more conservative approach toward estimating doses from 7 radioiodine in gaseous effluent.4. The radiation monitor set point determination method for liquid releases produces a set point value that is consistent the ODCM set point method.5. The EMS routine that is responsible for comparison of liquid effluent concentrations and MPC values is operating properly.6. The release duration adjustment term, t-*, is used consistently to the ODCH.80 4.0 SU12ARY OF DISCREPANCIES Discrepancy Area of Impact Potential Solution(s)

NRC NUREG-0133, Preparation of RadioloKical Effluent Technical Specifications for Nuclear Power Plants, October 1978.S 11 APPENDIX C: EMS SOFTWARE DOCUMENTATION 0 ATTACHMENT 2: RESOLUTIONS OF EMS SOFTWARE TEST REPORT DISCREPANCIES 0 C-4 ODCM Rev. 16 Attachment 2@ 2. Resolution of EMS Software Test Revort DiscreRancies The following discrepancy resolutions apply to the findings contained in the"Effluent Management System Test Report for Seabrook Station, May 1994" as noted on pages 9 and 10 (see Attachment
- 1 of Appendix C of the ODCM). With the positive resolution of the discrepancies identified in the EMS dose code, use of EMS as a computerized alternative approach (designated as Method IA in the ODCM) to determine compliance with the radioactive effluent dose and dose rate limits is acceptable since the results are comparable with the currently approved dose methods.Discrepancv:
Mixing ratio for shoreline activity used in EMS Program not equal to the value used in the ODCM Method I (Mp = 1.0).I Resolution:
The mixing ratio for the shoreline activity pathway in the EMS is consistent with the ODCM Method II approved value of 0.025, and therefore does provide for a calculated dose that is within the parameters already approved in the ODCM. The use of the EMS code (ODCM Method IA) for calculating liquid doses is acceptable for determining compliance with the dose limits of the Technical Specifications without the need to modify the assumption used for the shoreline mixing ratio.EMS dose factors based on Fp (fraction of year animals are on pasture) value which is not consistent with ODCM.I Resolution:
ODCM Method I assumes that the pasture season in the North East is 6 months long each year (Fp + 0.5). Method II allows for the pasture fraction to be set equal to 0.0 for the first and fourth quarters which equates the non-growing period of the year. The second and third quarters correspond to the growing season where the pasture fraction is assumed to be 1.0. The EMS software assumes an Fp value of 1.0 for animal grazing (meat and milk pathways) for all conditions.
This is a moderately conservative approach compared to Method I and the off grazing season conditions modeled in Method II. It is equal to the grazing season assumptions of Method II as applied in the second and third quarters.
As a result, the added conservatism in the EMS calculations for doses via milk and meat pathways are within acceptable margins and guidance provided in NRC NUREG-0133 for demonstrating compliance with Technical Specification dose limits. No changes to the EMS software are necessary.
Discrepancy:
I Shielding factors (SF) applied uniformly to dose rates and doses in the EMS program.0 I I Attachment 2 2. Resolution of EMS Software Test Report Discrepancies (Continued)
I Resolution:
The EMS program for gaseous releases incorporates a shielding factor (SF) equal to 1.0 for both dose rate and total dose determinations.
In contrast, both Method I and II use a SF value of 1.0 instantaneous dose rate calculations, but a value of 0.7 for integrated doses based on assumptions in NRC Reg. Guide 1.109. The use of a SF equal to 1.0 for the external ground plane exposure pathway for both dose rate and total dose is a moderately conservative assumption that is within the bounds already assumed in the ODCM dose modeling.
As a result, no modification to the EMS code as an acceptable approach (Method IA) for demonstrating compliance with Technical Specification dose/dose rate limits is required for SF.I Discrepancy:
Incorrect receptor location identified on EMS printout for ground level release point.I Resolution:
Incorrect name is identified on report with no impact on dose or dose rate calculations which were verified to be correct.I Discrepancy:
Assumed fraction of elemental iodine used in EMS program differs from ODCM Methods I and II._Resolution:
For ODCM Methods I and II, the fraction of elemental iodine assumed for gaseous releases in 0.5 based on the guidance in NRC Reg. Guide 1.109. The EMS code assumes an elemental iodine fraction of 1.0 based on the guidance in NUREG-0133.
Consequently, the EMS program (Method IA) will produce a moderately conservative estimate of dose impact (factor of 2) for iodine radionuclides if present'in the release estimations when compared to existing approved methods. As a result, no modification to the EMS code is necessary for use in the ODCM for determining compliance with Technical Specification dose limits.I Discrepancy:
I Missing organ dose rate information on EMS printout for effluent discharges containing 1-131, 1-133, H-3, and particulates.
Resolution:
This required information is easily obtainable from the permit closure process with flashing indication if any dose or dose rate limits are exceeded.2 APPENDIX C: EMS SOFTWARE DOCUMENTATION ATTACHMENT 3: SOFTWARE REQUIREMENTS SPECIFICATION FOR NORTH ATLANTIC ENERGY SERVICE CORPORATION, SEABROOK STATION, EFFLUENT MANAGEMENT SYSTEMS, REVISION 04, FP 75486 0 C-5 ODCM Rev. 16 Software Requirements Specification for North .Atlantic Energy Services Corporation Seabrook Station Effluent Management Systems 48-8448 Revision 04 Nuclear Data Systems Division Software Product Originator:

A-1 igo 0 .0 9 CHAPTER 1 INTRODUCTION The Effluent Management System (EMS) Software implements the requirements for determining limits and doses for the routine liquid and gaseous releases from nuclear power plants. The calculations and methodology are based on those described in U. S. Nuclear Regulatory Commission Regulatory Guide 1.109 and references described therein. These equations reduce to those described in NLTREG-0133 by proper selection of parameters.
This manual describes the calculations used in the LRW/GRW program for handling liquid and gaseous releases and -preparing the semi-annual report, and the equations used in the DFP option for calculating the relevant dose factors.This manual describes the new IOCFR20 (1992) as well as old 10CFR2Q requirements.
For a nuclear power plant, the Off-Site Dose Calculation Manual (ODCM) describes the methods used at that plant for complying with the effluent release portions of the technical specifications and the requirements of 10CFR20 and Appendix I of 10CFR50.The concentration and dose limits that are required to be met are: o For radioactive liquid effluents, the concentrations released to areas beyond the site boundary are limited to: MPC values given in old lOCFR20, Appendix B, Table II.OR ECL values given in new 10CFR20, Appendix B, Table 2.where ECL values are effluent concentration limit values.o For radioactive liquid effluents, the maximum dose to any member of the public will be less than the limits given in 10CFR50, Appendix I.o For gaseous effluents, the old 10CFR20 requires that the dose rate at any location beyond the site boundary will be limited to the annual dose limits given in the Technical Specifications and corresponding to the concentrations in Appendix B of the old 10CFR20. The old IOCFR20 approach for gaseous effluents has been accepted by the NRC for use under the new 10CFR20.I*W 1-1 Q-CUi4( razz o For gaseous effluents, the maximum dose to any member of the public will be less than the limits given in l0CFR50, Appendix I.o The maximum dose to any member of the public will not exceed the limits given in 40CFR290.The equations employed for calculating the dose and dose factors are.taken from NUREG-0133 1 and Regulatory Guide 1.109.2 For a particular nuclear plant,. the ODCM describes the physical configuration of release sources and release points for routine and non-routine liquid and gas.eous effluents, the monitor setpoint calculations, dose, and dose rate calculations.
.1.1 SETPOINT CALCULATIONS Calculations are made for the radiation monitors to determine the alarm/trip setpoint so that IOCFR20 compliance is met. For the'old 10CFR20 *compliance, liquid' calculati'ons use the maximum perinissible concentrations from IOCFR20 App. B, Table 2, column 2, and the more conservative value (smaller) of the soluble and insoluble values while gas calculations use dose rate equations and limits from NUREG-0133.
To comply with the new 1OCFR20 requirements, the effluent concentration limits are used for liquid setpoint calculations.
For gaseous setpoint calculations under the new 10CER20, the NRC is still allowing the use of dose rate equations and limits from NUREG-0133..
In the terminology of EMS, individual sources of radiation, such as storage tanks, the- containment building, etc., are defined as"release points." Several release points may lead to the same"discharge point." Setpoint calculations produce monitor limiting values in activity units (pCi/ml or pCi/cc). These are then converted to user units, e.g. counts per minute (cpm). For gaseous releases, setpoint can be reported as release rates (pCi/secl.
The reporting units for each monitor can be defined separately.
EMS allows setpoints to be set for both the release points and the discharge points. In the case that the release point and the discharge point are the same, or use the same physical monitor, the same discharge setpoint value is reported for both. This use of the same discharge setpoint value can be disabled.
0 1-2 EMS has a "nuclide specific" option. In this option only the nuclides listed in the monitor slope table are used in the setpoint calculations.
- I&2.2. RELEASE PROCESSING For batch releases, the processing of releases consists of sampling the tank or volume of air, analyzing the radionuclide content, then using the radionuclide concentrations and -estimated release flows, volumes, etc. and calculating the doses and setpoints, comparing to the 10CFR20 limits, and comparing to the IOCFR50 limits. If the limits are not exceeded, the pre-release permit is signed off and the release can occur. After the release, post-release processing performs the same calculations (except the setpoints are not needed)and the database is updated with the actual values for the release.For continuous releases, many installations prefer not. to generate an actual pre-release permit, but for the sake of aonalogou's operation, pre-release calculations must still be made in EMs.After review, the post-release calculations are made to update the database.EMS does not allow more that one open release at a time for a single release point. However, multiple releases may be open for one discharge point. Also, for-discharge points, the setpoint is calculated by summing over all open releases for. the time period involved.
An alternative approach if a new permit must be opened before the actual information for the previous permit are available is to go ahead and close the release using the pre-release values and then edit this closed release later when the actual information becomes available.
1.3 COMPOSITE NUCLIDES The standard radionuclide analysis, with high-resolution germanium detectors, quantifies the gamma-emitting radionuclides.
Pure beta emitters, nuclides that decay by K-capture, and alpha emitters are handled with other detection mechanisms.
These are usually not tracked individually by sample, but as a composite of many samples over a month or quarter period. The concentrations of the composite nuclides are combined with the concentrations of the individual nuclides determined from gamma analysis for each sample.i-3 i For liquid releases, the composite nuclides are generally H-3, Fe-55, Sr-80, Sr-90, and gross alpha. For gaseous releases, Fe-55 is generally not included.In EMS, these are contained in an editable file designated by the composite ID number. Each release point definition specifies which composite ID is used with the release point. These 'can be the composite nuclides, or any other nuclides desired.Composite samples produced by taking portions of the samples from individual releases are analyzed after the releases are over. Since these generally do not vary much from one period to the next, it is common to'use the most recent values. However, EMS provides the option of updating the composite values for the proper time period.and recalculating.
the activity and dose.values in the database.The EMS composite update process processes only those nuclides listed in the.Composite ID for-the release point. For each nuclide, the curies and doses based -on the previous value are subtracted from the. cumulative totals and the curies and doses based on the correct value are added into the cumulative totals.For the setting of flags to control options in the EMS NAESCO Seabrook Station EMS Operator's Manual 07-0589.code, see the So 1-4 P') q ODQ- &CeQ zZQ 00 CHAPTER 2 LIQUID RELEASE CALCULATIONS 2.1 LIQUID PRE-RELEASE PERMIT A liquid pre-release permit is generated with a program that uses the nucli'de activities to determine the radiation monitor setpoint (for 1OCFR20 compliance) and the potential doses for 10CFR50.compliance.
leo Continuous releases are treated similarly.
2.2 1OCFR20 COMPLIANCE IOCFR20 compliance calculations are broken down into two paths. The first path calculates compliance with the old 10CFR20 in which the calculations are based on Maximum Permissible Concentrations.
The second path complies with the new IOCFR20 and is Effluent Concentration Limits based.20CFR20 requires that the sum of concentrations divided by MPC (old 10CFR20) or ECL (new 10CFR20) values must not exceed unity for MPCs or 10 for ECLs: OLD IOCFR20 NEW lOCFR20 S = Z% C./ECL5 10 1 1L i S Z. C./HPC. E 1 1 1 1 ORI for concentrations Ci released from the site. MPCi is the maximum permissible concentration from the old lOCFR20, Appendix B, Table Ii, Column 2, for nuclide i and ECLi is the effluent concentration limit from the new 10CFR20, Appendix B, Table 2, Column 2, for nuclide i.2-1 tjf If the summation is greater than the limit, then dilution is required.
The required dilution factor is: If the IOCFR20 option is OLD: C.MPC.req f R max where Dreq = Total required dilution factor Ci = Concentration of nuclide .i in pCi/mL MPCi = Maximum permissible concentration of nuclide i in pCifrnL f IRelease point setpoint safety factor (usually equal to.0.5) from the release point definition.

and the sums extend over gamma-emitters (g) and non-gamima!-ernitters (ng), respectively.
Any nuclides with MPCi i 0 are excluded from the sum.Any nuclides with ECLi i 0 are excluded from the sum.The available dilution flow is the minimum dilution stream flow that can be ensured for the period of the release, corrected for other releases in process and any-activity in the dilution stream, and reduced by a safety factor.F avail =F (ff/100) (1 -E C./XXX.)aal ant f1 1 where Ci = Concentration (pCi/ml) for nuclide i for the dilution stream sample XXXi = MPCi or ECLi ff = Flow safety factor, in percent Fant = Anticipated dilution flow rate for the release-The anticipated dilution factor is then Dant F waste+ falloc Favail /Fwaste where Fwaste waste flow anticipated for this release Fa.i= available dilution flow avail falloc= fraction of available dilution stream flow allocated to this release 00 OWL~k R'V _ Z Dissolved and Entrained Gases To implement 10CFR20, it is also required that the total concentration of dissolved and entrained gases in liquid effluents be less than a specified value (normally, 2 E-04 pCi/nmL under OLD.10CFR20, or I E-04 PCi/mL under NEW 10CFR20).
EMS stores this limit in the Activity Limits transaction, checks this limit for each liquid permit, and indicates on the permit approval screen whether or not it is exceeded.
To include dissolved noble gases in the Dreg calculation, the database must also contain the same limiting value, as the liquid HPC or ECL for each noble gas nuclide.2.3 MAXIMUM WASTE FLOW The maximum waste flow calculation is based on the setting of the SETOPT option in the WELOW M class of options in the Release Point Setpoint definition.
This option can take on four values: NONE, NWAS (no waste), CALC or DOSE. For liquid releases, NONE, NWAS, and CALC are allowed.For liquid releases, Wmax the minimum of R1wmax and Rcwmax where Wmax =Maimum permissible waste flow rate for this release Rwmax -Release point maximum waste flow rate, as'set in the release point definition If the SET OPT option.= NONE: Rcwmax waste flow rate for the sample, Fwaste If the required dilution factor, Dreq (section 2.2) for the sample is greater than 1, Rcwmax becomes: Favail falloc Dreq -1.0 If the SET OPT option -CALC Favail

These may change Sadj as follows: If the SETPEQN is set to DILUT, and Fwaste > 0, then: Fant + Fwaste Sadj=Fwaste If the SETP__EQN is set to STD, and the SET_OPT option is set to NWAS, and Fwaste > O then: falloc 0 Favaii Sadj Fwaste

The setpoint adjustment factbr is further tested against, a limiting value (Sadj lim which is set using the.Release Point transaction in Database MAntenance).
if Sadj > Sadj,lim'then Sadj = Sadj,lim All of this leads to the maximum setpoint value, Smaxt based on the ganmma-emitting radionuclide mix: S max (i/ml) Sadj I Ci where the sum extends over all gamma-emitting nuclides (nudlides of type other than 0) in which their concentrations are greater than 0.In user units (cpm or other as set- in the Flow Monitor" Parameters transaction in Database Maintenance), the maximum setpoint is: Smax (cpm) =S adj(RMon -B) + B where B = monitor background (cpm)Rmon = monitor response (cpm)= offset + slope 0 Z C. + quad * (X Ci)2 + B where offset, slope, and quad are the coefficients

In the nuclide-specific case, Z (offseti+

The user can restrict which setpoint value is usually reported by what values are used when setting these tolerance factors and default setpoint values.The default setpoint i'n user units (e.g. cpm). can be defined with or without background included.
If the cunitnopt parameter (defined in the release point and discharge point tables) equals 0, the-default value does not include background;
'and the current background is added to the default value to get the reported-default setpoint.Otherwise, the current background is not added to the default value.Setpoint in .Ci/m.Note: In this version of the software, the reported setpoint is the user units setpoint.
The setpoint calculations using the original concentrations

To get reported setpoints in pCi/ml, the monitor slope should be set to 1.0 in the Release Point transaction of Database Maintenance and the UNITS parameter for the monitor should be set to puCi/ml in the Activity Monitors transaction.
If the Isotopic specific response option is turned on for the release point, then this individual nuclide slopes in the Monitor Slopes can be used to map the response from the nuclide to that of a monitor calibration source (e.g. Cs 1 3 7 equivalent response)2-4 A candidate setpoint is calculated based on the expected response: Sexp= ftol z Ci where ftol= setpoint tolerance factor (can be set for the release point using QBF)2 if not specified by the user Now compare the Sexp value to the default table value Sdef: If SeXp < Smax and if Sexp< Sdef and Sdef _.

Setpoints in MCi/sec Setpoints in units of pCi/sec can be obtained by setting the UNITS parameter for the monitor to "pCi/s" or "pCi/sec" (Case sensitive.
Ist 5 characters must match) in the Activity Monitors transaction and setting the monitor slope to 1.0 as in the pCi/ml setpoint calculation.
The user units 'setpoint, as calculated:
above for the setpoint in pCi/ml units, will be multiplied by the corresponding effluent flow rate (release point or discharge point) for the monitor to get a reported setpoint in pCi/sec.2.6 DOSE CALCULATIONS FOR LIQUID RELEASES The EMS software calculates and stores the dose for each receptor, for.each nuclide, and for each organ. The dose is the total .over all pathways which apply to that receptor.
A receptor is .defined by receptor ID, age group (infant, child, teen, or adult), sector, and distance from the plant.The equation used in the liquid permit processing to calculate the dose received by receptor r from a released nuclide i is: D =A.

Separate mixing ratios are stored for each pathway for each .receptor.
A mixing ratio of zero for a pathway receptor indicates that the pathway is not present for the receptor.

The different mixing ratios for the pathways are incorporated into the composite Ai factors calculated by the dose factor processing (DFP) program.Fqvol Fl.ow rate from user entered quarterly dilution flow rate. These values are from the AFLOW column of the QDVOL table for the-release.
If stream flow option is being used and the average river stream flow is known at the time the liquid release is processedi then the command procedure which runs the liquid permit processing could be'modified to ask for the stream flow value and put it into the stationdata table before the permit is processed.
If the average river stream flow is not known at the time the liquid release is processed, then some other provision must be made for correcting the cumulative dose totals in the CUMDOSE table so that it is based on the correct stream flow value. If the average streamflow for 2-16 the month is used, then each liquid release point entry in the CUMDOSE table f or the month could be multiplied by the ratio of the&ctual stream flow for the month divided by the default value contained in the STATIONDATA table. Caution: Since there is no record stored in the database of what stream flow value was used to calculate the dose values, the user must verify that no correction is applied more than once to each dose value.2.7 31 DAY.PROJECTED DOSE CALCULATIONS The 31 Day Projected Dose values appear on the Standard and Special iiermit Reports. The Projected Dose values are calculated as follows: DpT (DT p) + DaT where: DPT =the 31 Day Projected Dose by organ T, by reactor unit DT =the total dose in mrem by organ T, by reactor unit for the quarter containing the release start date from all closed and open releases when an answer of "Y" is specified for the "Update Totals" field on the release point definition screen.-p =the Projection Factor which is the result of 31 divided by the number of days from start of the quarter containing the release start date to the end of the release. The quarterly and annual projection values on the standard pre-release report use a projection factor with 92 days or 365 days instead of 31 days in the numerator and do not include the additional anticipated dose term.DaT =Additional Anticipated Dose for liquid releases by organ T and quarter of release by reactor unit.NOTE: The 31 day dose projections on the Approval/Results screen is the site total for all units.2.8 POST-RELEASE PROCESSING After the release is made, actual concentrations are used to check 10CFR20 limits, and the actual dilution flow and waste flow are used instead of the anticipated dilution flow and waste flow.2-17 L3 o For batch releases, t'he duration is determined from the start and end dates and times, and is used with the volume input to calculate the release rate.Dose calculations are the same as for the pre-release, but with actual release flow rates and release duration.Setpoint calculations are not performed at the post-release stage.2-18 ~5L'2-:18 P-5 LO I CHAPTER 3 GASEOUS RELEASE CALCULATIONS The "annual average X/Q" method is used, in which fixed X/Q and D/Q values are used fox each receptor for all dose calculations, regardless of actual wind direction and speed prevailing during a given release. Doses are calculated for each receptor location and age group specified in the Gas Rec-eptors transaction.
The controlling individual is the age group and location which receives the maximum organ dose.3.1 GAS PRE-RELEASE PERMIT The pre-release permit is produced by a program that uses user-entered estimates of flow rates and- release times to calculate doses and activities.
The dose rate from the potential release is added to the maximum dose rate occurring for all other releases during the duration of this release for IOCFR20 compliance.
The noble gas or air dose's and the organ doses are checked against the corresponding limits for IOCFR50 compliance.
3.2 RADIONUCLIDE ACTIVI.TIES AND COMPOSITE VALUES The radionuclide results are read from one set of composite activity database records, and from three spectrum analysis result files, and saved in an activity array. If a nuclide appears in more than one spectrum, only the last value read for that nuclide is used. In case of duplication, the one not desired should be edited out of the nuclide list. The samples are read in the following order: 3-1 -c j r-bcik w Z~Z.

The database contains all releases for which both pre- and. post-release reports have been made (the post-release program enters the data into the cumulative totals). Pre-releases that have not been completed, and which occur during the release under consideration, are also added into the maximum dose rate to account for releases not yet added to the cumulative totals.The three dose rates (whole body, skin, organ) are compared to the old 10CFR20 limits (old and new IOCFR20 are described below) as defined in the Dose Limits transaction in Database Maintenance.

SETPOINTS Setpoints are determined for radiation monitors on individual release points, and also for radiation monitors at the discharge points that may combine the effluent from several release points.Calculations for the monitor response are made for noble gases, radioiodines, and particulates.
For a release point, the expected monitor response to a given nuclide concentration is: Rmon = monitor response (cpm) !+ B= offset + [slope.

where offset, slope, and quad are the coefficients in a quadratic fit to the monitor response to nuclide activity, and B is the monitor background.
EMS provides an option to calculate nuclide specific responses so that Rmon is determined from the response for each nuclide, rather than the sum of the nuclide concentrations, as shown above. In that case, Rmon ( offseti + [slopei a Ci] + [quadi * (Ci)2 J) + B-The expected response for discharge points is based on the sum of the expected response for releases already in progress plus the expected response due to release point being considered.

The summation extends over all applicable nuclides and pathways.3.7 RESOLVING DOUBLE-COUNTING' OF DOSE AND ACTIVITY Gaseous release points fall into three categories for double-counting of dose and activity.
One, a release point will not have activity sampled twice. Two, a release point can have activity that is sampled again downstream and would be double-counted if no corrections were applied. Three, a release point can have samples containing activity already sampled once upstream which would. be double-counted if no corrections were applied. The last two categories can be called the "CAUSE" release point and the "EFFECT" release point, respectively.
To avoid double-counting dose and-activity, only the "EFFECT" release point will have its activity and concentrations corrected as follows. Corrected activity is calculated as follows: Acei Aei Aci where.: Acei =the corrected "EFFECT" release point activity for nuclide i which defaults to zero if its value is less than zero.Aei =the initial "EFFECT" release point activity for nuclide i Aci =the "CAUSE" release point activity for nuclide i Corrected concentrations are calculated as follows: Ccei (Acei / Ve) 6 35.315 3-16 where: Ccei =the corrected I"EFFECT" release point concentrations for nuclide i Ve =the waste volume for the "EFFECTi T release point 35.315 =conversion factor from Ci/ft 3 to FCi/ml (Ci/ft 3 ft 3/1728 in 3 d in 3/16.387 cm 3)3.8 31 DAY PROJECTED DOSE CALCULATIONS The 31 Day Projected Dose values appear on the Standard and Special Permit Reports. The Projected Dose values are calculated as follows: DpT I(DT P) + DaT where: DpT =the 31 Day Projected Dose.by organ T, by reactor unit DT =the total dose in mrem *by organ T, by reactor unit for the quarter containing the release start date from all closed and open releases when an answer of "Y" is specified for the-"Update Totals" field. on the release point definition screen.p =the Projection Factor which is the result of 31 divided by the number of days from the start of the quarter to the end of the release. The quarterly and annual projection values on the standard pre-release report use a projection factor with 92 days or 365 days instead of 31 days in the numerator and do not include the additional.
anticipated dose term.DaT =Additional Anticipated Dose for gaseous releases by organ T and quarter of release, by reactor unit.NOTE: 'The 31 day dose projections on the Approval/Results screen is the site total for all units.3-17 3.. 9 GAS POST-RELEASE PROCESSING After a pre-release permit has been approved, the post-release program is run to: o Enter actual release start and stop times, flow rates, etc.o Check IOCFR20 limits o Check 1OCFR50 limits o Add.the dose and- activity data into the cumulative totals.Compliance with IOCFR20 limits is checked in the same way as-described for the pre-release program..Dose rates are calculated and compared to 10CFR20 limits. Monitor sjetpoints are not calculated at the post release stage.0., 3-18 79 0.CHAPTER 4 LIQUID DOSE FACTOR EQUATIONS The DFP option is used to calculate the liquid dose factors described previously.
Dose factors are calculated separately for each nuclide, organ, and age group. The age group, applied to a specific receptor's dose calculations, is part of the receptor specification.
For a particular receptor, the total dose factor (AiT~r) is a sum over each pathway p with its specific mixing ratio: AiTr m ixr,p A r,p XR .mix, r where AiTr,p =the dose factor for nuclide i, organ T, receptor age group r, and pathway p mix, r,p mixing ratio for the pathway Rmix,r -mixing ratio for the receptor, which is the first non-zero value of "ix,r,p encountered during the calculation The user specifies which pathways are included by setting the mixing ratios for the pathways desired to the correct non-zero Value. If the receptor mixing ratio for a given pathway is zero, that term is not included in the sum.0@4-:1 re,/ 12-The DFP option of EM-S uses a more expanded form for iicuid dose factors than is given in NUREG-0133.
These equations are taken from R.G. 1.109, and account for nuclide decay as well as-shoreline doses. If desired, parameters may be selected to reduce the calculations to match NUREG-0133 exactly.Four different forms of equations are used for the dose factors.4.1 POTABLE WATER The dose factor for potable water is: AiT.rjp= kO (U-rp /dw).

Dose factors are calculated separately for each nuclide, organ, and age group. The age group, applied to a specific receptor's dose calculations, is part of the receptor specification.
