There are no seismic/dead weight concerns related to the change to the ODCM.

B.46 Radvaste System Changes

>> The change to the ODCH does not involve a change to the Radvaste System.

>> The addition of the dewatering of the 24-inch pressure vessels and the use of the NuPac dewatering system does not change the Design Basis of the Solid Radvaste System. The use of NRC approved packages vill be used without significant exposure to the personnel performing the dewatering. The packages vill contain shielding or vill be devatered within a shield. The containers are designed so that the filling and devatering connections can be quickly and easily disconnected. Therefore this change to PCP does not prevent the Radwaste System from performing its design function and nuclear safety is not compromised.

B.49 Nev Radioactive

~

Effluent (Liquid or Gaseous> release pathway.

CI T

- The change to the ODCM cannot create a nev radioactive effluent.

- The addition of the 24-inch pressure vessels and NuPac Dewatering system vill not create a new liquid or gaseous effluent. All liquids released from these systems vill be routed to 1) the'Radwaste Floor Drain system, 2> the Radwaste Equipment Drain system, or 3 > the Maste Package Drain tank. All of these three subsystems are processed and sampled as part of the existing Liquid Radwaste System. The discharge rate of the devatering systems is veil within the capacity of the Radvaste System.

During the devatering process, the discharge air is passed through a high efficiency particulate air (HEPA) filter prior to its release into the surrounding area. The dewatering is performed within a permanent plant building in which the air is monitored prior to its release.

Therefore, no nev gaseous effluent pathvay is created.

Based upon the evaluations of the items on the checklist, this activity is safe.

KKLQRLH;-'.;;;; ~ ~ g.

Because, of its interface with the Radwaste Syitem and the changes to the,PCP may be construed as conflicting with the

Safety"&Pcs'iment foE ODCM Revision (Revision 9 to RATS Manual)

~ ~

q;g, ~, **

A. Description This revision to the ODCM will implement two sets of changes. The first set'of changes are corrections of typographical errors, grammatical errors, wording clarifications, and a complete renumbering of 'sections, tables and figures. These changes, since they o~. not intent changes, will require no evaluation for their effect. on nuclear safety, the SAR, or the Technical Specifications (T/S).

The second set of changes adds text to the ODCM which duplicates text currently found in the Technical Specifications and/or the Radiological Effluent Manual (REM). This change is in anticipation of a T/S change which will implement the NRC's Generic Letter 89-01. The Generic Letter recommended the relocation of all procedural details in the T/S dealing with radioactive gaseous and liquid effluents to the ODCM. The affected Sections of the T/S and REM are listed below:

Specifications 3.2.D, 3.2.K, most of Section 3.8/4.8 (with the exception of the explosive gases requirements which will remain in the T/S and the solid waste requirements which should be moved to the Process Control Program as recommended by the Generic Letter),

and all of the REM text is relocated to the ODCM. A detailed

'cross>>'reference for the current T/S, REM, and proposed ODCM Sections is given in the attachment. II I lW t

In addition to the recommended changes, applicable terms which are defined in the T/S will be duplicated in the ODCM so that it will be a self-contained document upon the implementation of a T/S change.

The duplicated definitions are also given in the attachment.

The text which is being duplicated is done so verbatim, with the exception of references between documents and correction of typographical errors. The current text in the TS and the REM cross references the ODCM, the REM and other TS sections. The new ODCM wording will only reference other sections of the ODCM and, in some cases, portions of the TS which will still be applicable.

The only systems potentially affected by a change to the ODCM will be the liquid and gaseous effluent and process monitoring systems described in the BFN FSAR. Since this revision does not change any calculational methodology, requirements, or processes, it will not have any effect on these systems.

This ODCM revision places text in the ODCM which duplicates text found in T/S. It does not change any design characteristics, functional requirements, or methodology for dose calculations and setpoint calculations that are described in the FSAR. Any references in the FSAR to the T/S themselves will continue to be valid, as will references to the ODCM as the location for methodology for dose and setpoint calculations. Therefore, this revision will have no effect on the FSAR text.

This revision does not change any equipment, requirements, methodology, or descriptions of any of these, nor does it change the way in which All descriptions in the SAR will any requirements are implemented.

continue to be valid after this revision.

This ODCM revision will not require any new procedures or instructions or revisions to existing procedures or instructions.

RETS Manual Revision 9 Page 4 RETS Manual Section I INTRODUCTION The Radiological Effluent Technical Specification (RETS) Manual contains three documents; the Radiological Effluent Manual (REM), the Offsite Dose Calculation Manual (ODCM), and the Process Control Program (PCP). All three documents are referenced by the Radiological Effluent Technical Specifications which vere issued on February 5, 1987 as Technical Specification Amendments Nos. 132, 128, and 103 to unit 1, 2, and 3, respectively.

The REM and the ODCM vere approved by the NRC when they issued the RETS.

The REM is controlled by the NRC, so changes to the REM must be approved by the NRC before they are put in this manual. The ODCM and PCP are controlled b TVA 60 so cchanges to the ODCM and the PCP must be approved by PORC. Initial NRC approval of the PCP is required and has been requested.

RETS Manual Revision 9 Page 7 The purpose of this manual is to provide the sampling and analysis programs which provide input to the ODCM for'calculating liquid and gaseous effluent concentrations and offsite doses. Guidelines are provided for operating radioactive waste treatment systems in order that offsite doses are kept as-low-as-reasonable-achievable (ALPS).

The Radiological Environmental Monitoring Program outlined within this manual provides confirmation that the measurable concentrations of radioactive material released as a result of operations at the Browns Ferry Plant are not higher than expected.

En addition, this manual outlines the information required to be submitted to the NRC in both the Annual Radiological Environmental Operating Report and the Semiannual Radioactive Effluent Release Report.

RETS Manual Revision 9 Page 11 TABLE NOTATION TABLE C<<l (1) A batch release is the discharge of liquid wastes of a discrete volume.

The discharge shall be thoroughly mixed prior to sampling.

(2) A proportional composite sample is one in which the quantity of liquid sampled is proportional to the quantity of liquid waste discharged from the plant and is representative of the liquid discharged.

(3) The LLD is defined, for the purposes of these specifications as the smallest concentration of radioactive material in a sample that will yield a new count (above system background) that will be detected with 95K probability with only 5'X probability of falsely concluding that a blank observation represents a "real" signal.

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

4.66 sb E w V

• 2.22 x 10

• Y

• exp (-Xdt)

Where:

LLD is the "a priori" lower limit of detection as defined above (as microcuries per unit mass or volume),

sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute),

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

V is the sample size {in units of mass or volume),

2.22 x 106 is the number of disintegrations per minute per microcurie, Y is the fractional radiochemical yield (when applicable),

X is the radioactive decay constant for the particular radionuclide, and ht for plant effluents is the elapsed time between the midpoint of sample collection and time of counting.

Typical values of E, V, Y, and ht should be used in the calculation.

It should be recognised that the LID is defined as a priori (before the fact) limit representing the capability of a measurement system and not as an a posterior (after the fact) limit for a particular measurement.

RETS Manual Revision 9 Page 13 C.2 LI UID RADIOACTIVE WASTE TREATMENT This section requires that the appropriate portions of the liquid radwaste treatment system be used when specified. This 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 Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and design objective 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 guide set forth in Section II.A of Appendix I, 10 CFR Part 50, for liquid effluents.

This section also requires submittal of a special report if the limiting values are exceeded and unexpected failures of non-redundant radwaste processing equipment halt waste treatment.

The liquid radwaste system shall be used to reduce the radioactive materials in liquid wastes prior to their discharge from the site when the projected monthly dose would exceed 0.06 mrem to the total body or 0.21 mrem to any organ per unit (see Figure 4'.8-lb, Technical Specification).

Doses due to liquid releases to unrestricted areas shall be projected at least once per 31 days, in accordance with the ODCM.

With radioactive liquid waste being discharged for more than 31 days without treatment and when the projected dose is in excess of limits specified above prepare and submit the Special Report pursuant to Section 6.7.2 of the Technical Specifications.

RETS Manual Revision 9 Page 16 TABLE NOTATION TABLE D>>1 (1) The LLD is defined, for the purposes of these specifications as the smallest. concentration of radioactive material in a sample that will yield a new count (above system background) that will be detected with 95'X probability with only 5'X probability of falsely concluding that a blank observation represents a "real" signal.

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

4.66 sb E + V + 2.22 x 10

• Y + exp (-Xht)

Where:

LLD is the "a priori" lower limit of detection as defined above (as microcuries per unit mass or volume),

sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute ),

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

V is the sample sire (in units of mass or volume),

2.22 x 106 is the number of disintegrations per minute per microcurie, Y is the fractional radiochemical yield (when applicable),

X is the radioactive decay constant for the particular radionuclide, and ht for plant effluents is the elapsed time between the midpoint of sample collection and time of counting.

Typical values of E, V, Y, and 4t should be used in the calculation.

lt 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 posterior (after the fact) limit for a particular measurement.

(2) When samples are taken more often than that shown, the minimum detectable concentrations can be correspondingly higher.

D-3 828o

RETS Manual Revision 9 Page 17 (3) The principal gamma emitters for which the LLD specification will apply are exclusively the following radionuclides: Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135, and Xe-138 for gaseous emissions and Hn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, Ce-141, and Ce-144 for particulate emissions. This list does not mean that only these nuclides are to be detected and reported. Other peaks which are measurable and identifiable, together with the above nuclides, shall also be identified and reported. Nuclides which are below the LLD for the analyses should not be reported as being present at the LLD level for that nuclide.

(4) Analysis shall also be performed if the radiation monitor alarm exceeds the setpoint value.

RETS Manual Revision 9 Page 19 RADIOLOGICAL ENVIRONMENTAL MONITORING SAMPLING AND ANALYSIS The radiological monitoring program required by this section provides measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides, which lead to the highest potential radiation exposures of individuals resulting from the station operation.

This monitoring program thereby supplements the radiological effluent monitoring program by verifying that the measureable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis, of the effluent measurements and modeling of the environmental exposure pathways.

The radiological environmental monitoring program shall be conducted as specified in Table E-l.

The radiological environmental monitoring samples shall be collected pursuant to Table E-1 from the locations given in the table and figure in the ODCM and shaLl be analyzed pursuant to the requirement of Table E-1 and the detection capabilities required by Table E-2.

With the radiological environmental monitoring program not being conducted as specified in 'Table E-l, in lieu of a LER, prepare and subm'.

to the Commission, in the Annual Radiological Operating Report, a description of the reasons for not conducting the program as required and the plans for preventing a recurrence.

Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal unavailability or malfunction of automatic sampling equipment. If the latter, every effort shall be made to complete corrective action prior to the end of the next sampling period. All deviations from the sampling schedule shall be reported in the Annual Radiological Environmental Operating Report.

With the level of radioactivity in an environmental sampling medium exceeding the reporting levels of Table E-3 when averaged over any calendar quarter, in lieu of a LER, prepare and submit to the Commission within 30 days from the end of the affected calendar quarter, a report which identifies the cause(s) for exceeding the limit(s) and defines the corrective action 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 the Technical Specifications. When more than one of the radionuclides in Table E-3 are detected in the sampling medium, this report shall be submitted if:

Conc(1) + Conc(2) + ... > 1.0 Limit(l) Limit(2)

When radionuclides other than those in Table E-3 are detected and are result of plant effluents, this report shall be submitted if the potential annual dose to a member of the public is equal to or greater than the calendar year limits of the Technical Specification.

E-1 828o

RETS Nanual Revision 9 Page 20 Such reports are 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.

With milk or fresh leafy vegetabl.'e samples unavailable from one or more of the sample locations required by Table E-1 identify locations for obtaining replacement samples, if available, and add them to the radiological environmental monitoring program within 30 days. The specific locations from which samples were unavailable may then be deleted from the monitoring program.

In lieu of a LER, identify the cause of the unavailability of samples and identify the new location(s), if available, for obtaining replacement samples in the next Annual Radiological Environmental Operating Report and also include a revised figure(s) and table(s) for the ODCM reflecting the new locations.

The provisions of Technical Specification 1.0.C are not applicable.

The detection capabilities required by Table E-2 are state-of-the-art for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of the measurement system and not as an a osterior {after the fact) limit for particular measurement. Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions, Occasionally background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable.

In such cases, the contributing factors will be identified and described in the Annual Radiological Environmental Operating Report.

828o

RETS Manual Revision 9 Page 21 E.2 LAND USE CENSUS A land use cens us shall be conducted and shall identify the location of the nearest milk animal, the nearest residence and the nearest garden* of greater than 500 square feet producing fresh leafy vegetables in each o the 16 meteorological sectors within a distance of five miles. (For elevated releases as defined in Regulatory Guide 1.111, Revision 1, July 1977, the land use census shall also identify the locations of all milk animals and all gardens of greater than 500 square feet producing fresh leafy vegetables in each of the 16 meteorological sectors within a distance of three miles).

With a land use census identifying a location(s) which yields a calculated dose or dose commitment greater than the maximum value currently being calculated in section D.2 of this manual, in lieu of a LER, identify the new locations in the next Annual Radiological Environmental Operating Report.

With a land use census identifying a location(s) that yie1ds a calculated dose or dose commitment (via the same exposure pathway) 20 percent greater than at a location from which samples are currently being obtained in accordance with section E.l, add the new location(s) to the radiological environmental monitoring programs .within 30 days if the owner consents. 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 3) of the year in which this land use census was conducted. ln lieu of a LER, identify the new location{s) in the next Annual Radiological Environmental Operating Report and provide a revised figure(s) and table for the ODCM reflecting the new location(s).

~Broad leaf vegetation sampling may be performed at the site boundary in the direction section with the highest Dig in lieu of the garden census.

828o

RETS Manual Revision 9 Page 22 The land use census shall be conducted at least once per calendar year between .the dates of April 1 and October 1 using the following techniques:

a~ Within a 2 mile radius from the plant or within the 15 mrem per year isodose line, whichever is larger, enumeration by a door<<to-door or equivalent counting technique.

b. Within a 5 mile radius from the plan, enumeration by using appropriate techniques such as door-to-door survey, mail survey, telephone survey, aerial survey, or information from local agricultural authorities or other reliable sources.

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

The best survey information from the door-to-door, mail, telephone, aerial or 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 500 square feet provides assurance that significant exposure pathways via fy vegetables 1 cay g will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/year) o leafy vegetation assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were used: 1) that 20'X of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and 2) a vegetation yield of 2 kg/square meter.

828o

RETS Manual Revision 9 Page 23 The requirement for participation in an Interlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive materials in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are reasonably valid.

Analyses shall be performed on radioactive materials supplied as part of an Interlaboratory Comparison Program which has been approved by the Commission.

A summary of the results obtained as part of the above required Interlaboratory Comparison Program and in accordance with the ODCM {or

, participants in the EPA cross check program shall provide the EPA program code designation for the unit) shall be included in the Annual Radiological Environmental Operating Report.

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.

RETS Manual Revision 9 Page 46 INTRODUCTION The Browns Ferry Nuclear Plant (BFN) Offsite Dose Calculation Manual (ODCM) is a supporting document of the BFN Technical Specifications. The ODCM is divided into two major parts. The first part of the ODCM contains: l) Radioactive Effluent Controls specified by the BFN Technical Specifications; 2) Radiological Environmental Monitoring Controls required by the BFN Technical Specifications; 3) descriptions of the information that should be included in the Annual Radiological Environmental Operating and Semiannual Radioactive Effluent Release Reports required by BFN Technical Specifications; and, 4) Administrative Controls for the ODCM requirements. The second part of the ODCM contains the methodologies used to: 1) calculate offsite doses resulting from radioactive gaseous and liquid effluents; 2) calculate gaseous and liquid effluent monitor Alarm/Trip setpoints; and, 3) conduct the Environmental Radiological Monitoring Program.

The BFN ODCM is maintained for use as a reference guide on accepted methodologies and calculations. Changes in the calculation methods or parameters will be incorporated into the ODCM in order to assure that the ODCM represents the present methodology in all applicable areas. Any licensee initiated ODCM changes will be implemented in accordance with BFN Technnical Specifications.

828o

RETS Manual Revision 9 Page 47 i ive waste release levels to Radioactive UNRESTRICTED AREAS should be kept "as low as reasonably achievable" and are not to exceed the concentration limits specified in 10 CFR Part 20, Appendix B, Table II. At the same time, the requirements specified in this manual permit the flexibility of operation, compatible with considerations of health and safety, to assure that the public is provided a dependable source of power under unusual operating conditions which may temporarily result in releases higher than design objectives but still within the concentration limits specified in 10 CFR Part 20. It is expected that by using this operational flexibility and exerting every effort to keep levels of radioactive releases "as low as reasonably achievable" in accordance with criteria established in 10 CFR Part 50, Appendix I, the annual releases will result in a small fraction of the annual average concentration limits specified in

~ ~

10 CFR Part 20, Appendix B, Table II.

The surveillance/testing requirements given in this manual provide assurance that liquid and gaseous wastes are properly controlled and monitored during any release of radioactive materials in the liquid and gaseous effluents. These requirements provide the data for the licensee and the Commission to evaluate the station's performance relative to radioactive materials released to the environment. Reports on the quantities of radioactive materials released in effluents shall be furnished to the Commission on the basis of Section 5.0 of this manual.

On the basis of such reports and any additional information the 1 Commission may obtain from the licensee or others, the Commission from time to time require the licensee to take such actions as the Commission deems appropriate.

RETS Manual Revision 9 Page 85 1/2. 1 EFFLUENT MONITORING INSTRUMENTATION 1/2.1 ~ 1 RADIOACTIVE LI UID EFFLUENT MONITORING INSTRUMENTATION The radioactive liquid effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in liquid effluents during actual or potential releases of liquid effluents. The alarm/trip setpoints for these instruments shall be calculated in accordance with guidance provided in the ODCM to ensure that the alarm/trip will occur prior to exceeding the limits or 10 CFR Part 20 Appendix B, Table II, Column 2. 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.

1/2.1.2 RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION 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 will be calculated in accordance with Section 7.2.1 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 action required when the number of OPERABLE channels is less than the Minimum Channels Operable requirement is specified in the notes for Table 1.1-2. Exert best efforts to return the instruments to OPERABLE status within 30 days and, if unsuccessful, explain in the next Semiannual Radioactive Effluent Release Report why the inoperability was not corrected in a timely manner.

1/2. 2 RADIOACTIVE EFFLUENTS 1/2.2.1.1 CONCENTRATION This requirement is provided to ensure that the concentration of radioactive materials released in liquid waste effluents from the site to UNRESTRICTED AREAS will be less than the concentration levels specified in 10 CFR Part 20, Appendix B, Table II, Column 2. This limitation provides additional assurance that the levels of radioactive materials in bodies of water outside the site will result in exposures within (1) the Section II.A limits of Appendix I to 10 CFR Part 50 to the population. The concentration limit for noble gases is based upon the assumption that Xe-135 is the 828o

RETS Manual Revision 9 Page 86 BASES 1/2.2 RADIOACTIVE EFFLUENTS 1/2.2.1.1 CONCENTRATION (continued) controlling radioisotope and its Maximum Permissible Concentration in air (submersion) was converted to an equivalent concentration in water using the methods described in International Comnission of Radiological Protection (ICRP) Publication 2.

1/2.2.1.2 DOSE This requirement is provided to implement the dose requirements of Section II.A, III.A, and IV.A of Appendix I, 10 CFR Part 50. The requirement implements the guides set forth in Section II.A of Appendix I.

This action provides the required operating flexibility and at the same time implements the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents will be kept "as low as is reasonable achievable". Also, for fresh water sites with drinking water supplies which can potentially be affected by plant operations, there is reasonable assurance that the operation of the facility will not result in radionuclide concentrations in the finished drinking water that are in excess of the requirements of 40 CFR 141. The dose calculations in Section 6.0 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 an individual through appropriate pathways is unlikely to be substantially underestimated. The equations specified in Section 6.0 for calculating the doses due to the actual release rates of radioactive materials in liquid effluents will be 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 Implementing Appendix I," October 1977 and Regulatory Guide 1.1.13, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I" April 1977.

NUREG-0133 provides methods for dose calculations consistent with Regulatory Guides 1.109 and 1.113.

1/2.2.1.3 LI UID WASTE TREATMENT This section requires that the appropriate portions of the liquid radwaste treatment system be used when specified. This provides assurance that the releases of radioactive materials in liquid effluents will be kept "as low as is reasonably achievable." This requirement implements the requirements of 10 CFR Part 50.36a, 828o

0 RETS Manual Revision 9 Page 87 BASES 1/2. 2 RADIOACTIVE EFFLUENTS 1/2.2.1.3 LI UID WASTE TREATMENT (continued)

General Design Criterion 60 of Appends A to 10 CFR Part 50 and design objective Section II.D of Appendix I to 10 CFR 50. The specified limits governing the use of appropriate portions of the liquid radwaste treatment system were specified as a suitable fraction of the guide set forth in Section II.A of Appendix I, 10 CFR 50, for liquid effluents.

This section also requires submittal of a special report if the limiting values are exceeded and unexpected failures of non-redundant radwaste processing equipment halt vaste treatment.

1/2.2.2.1 DOSE RATE This requirement is provided to ensure that the dose rate at anytime at the SITE BOUNDARY from gaseous effluents from all units on the site vill be vithin the annual dose limits of 10 CFR Part 20 for UNRESTRICTED AREAS. The annual dose limits are the doses associated with the concentrations of 10 CFR Part 20, Appendix B, Table II, Column 1. These limits provide reasonable assurance that radioactive material discharged in gaseous effluents vill not result in the exposure of a MEMBER OF THE PUBLIC in an UNRESTRICTED AREA, either vithin or outside the SITE B'OUNDARY, to annual average concentrations exceeding the limits specified in Appendix B, Table II of 10 CFR Part 20 (10 CFR Part 20.106(b)). For MEMBERS OF THE PUBLIC vho may at times be within the SITE BOUNDARY, the occupancy of the MEMBER OF THE PUBLIC will be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the SITE BOUNDARY.

The specified release rate limits restrict, at all times, the corresponding gamna and beta dose rates to an individual at or beyond the SITE BOUNDARY to ( 500 mrem/year to the total body or

< 3000 mrem/year to the skin. These release rates also restrict, at all times, the corresponding thyroid dose rate above background to an infant via the cow-milk-infant pathway to ( 1500 mrem/year for the nearest cow to the plant.

The action for this requirement requires that appropriate corrective action(s) be taken to reduce gaseous effluent releases if the limits are exceeded.

1/2.3.2.2 DOSE - NOBLE GASES This requirement is provided to implement the requirements of Section II.C, III.A, and IV of Appendix I, 10 CFR Part 50. The limits are the guides set forth in Section II.C of Appendix I.

RETS Manual Revision 9 Page 88 BASES 1/2. 2 RADIOACTIVE EFFLUENTS 1/2.2.2.3 DOSE I-131 I-133 TRITIUM AND RADIONUCLIDES IN PARTICULATE FORM This requirement is provided to implement the requirements of Section II.C, III.A, and IV of Appendix I, 10 CFR Part 50. The limits are the guides set forth in Section II.C of Appendix I.

The action to be taken for exceeding these limits provides the required operating flexibility and at the same time implements the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in gaseous effluents will be kept "as low as reasonably achievable." Section 7.0 calculational methods 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 an individual through appropriate pathways is unlikely to be substantially underestimated. Section 7.0 calculational methods for calculating the doses due to the actual release rates of the subject materials are consistent with the methodologies provided in NUREG/CR-1004, "A Statistical Analysis of Selected Parameters for Predicting Food Chain Transport and Internal Dose of Radionuclides," October 1979 and Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purposes of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.111, Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water Cooled Reactors," Revision 1, July 1977. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions. The release rate specifications for iodines, radioactive material in particulate form and radionuclides other than noble gases are dependent on the existing radionuclide pathways to man in the UNRESTRICTED AREA. The pathways which were examined in the development of these calculations were: 1) individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, 3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man, and 4) deposition on the ground with subsequent exposure of man.

If these limits are exceeded, this section requires that a special report be prepared and submitted to explain violations of the limiting doses contained in the section above.

828o

RETS Manual Revision 9 Page 89 BASES 1/2. 2 RADIOACTIVE EFFLUENTS 1/2. 2. 2. 4 GASEOUS RADWASTE TREATMENT This requires that the offgas charcoal adsorber beds be used when specified to treat gaseous effluents prior their release to the environment. This provides reasonable assurance that the release of radioactive materials in gaseous effluents will be kept "as low as is reasonable achievable". This requi.rement implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50, and design objective 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 guide set forth in Sections II.B and II.C of Appendix I, 10 CFR Part 50, for gaseous effluents.

This action requires that a special report be prepared and submitted to explain reasons for any failure to comply with the above requirements.

1/2.2.3 TOTAL DOSE This requirement is provided to meet the dose limi.tations of 40 CFR 190. This requirement requires the preparation and submittal of a Special Report whenever the calculated doses from plant radioactive effluents exceed twice the design objective doses of Appendix I. For sites containing up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR 190 if the individual reactors remain within the reporting requirement level. The Special Report will describe a course of action which should result in the limitation of dose to a member of the public for the calendar year to be wi.thin 40 CFR 190 limits. For the purposes of the Special Report, it may be assumed that the dose commitment to the MEMBER OF THE PUBLIC from other fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities within a radius of five miles must be considered.

1/2.3 RADIOLOGICAL ENVIRONMENTAL MONITORING 1/2.3.1 MONITORING PROGRAM The radiological environmental monitoring program required by this section provides measurements of radiation and radioactive materials in those exposure pathways and for those radionuclides, which lead to the highest potential radiation exposures of individuals resulting from the station operation. This monitoring program thereby supplements the radiological effluent monitoring 828o

RETS Manual Revision 9 Page 90 BASES 1/2. 3 RADIOLOGICAL ENVIRONMENTAL MONITORING

'1/2.3.1 MONITORING PROGRAM (continued) program by verifying that the measurable concentration of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways.

1/2.3.2 LAND USE CENSUS This requirement is provided to ensure that changes in the use of UNRESTRICTED AREAS are identified and that modifications to the monitoring program are made if required by the results of this census. The best survey information from the door-to-door, mail, telephone, aerial or consulting with local 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 SOO square feet provides assurance that significant exposure pathways via the 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 vegetation assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were used: 1) that 20K of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and 2) a vegetation yield of 2 kg/square meter.

1/2.3.3 INTERLABORATORY COMPARISON PROGRAM The requirement for participation in an Interlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive materials in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are reasonably valid.

The following equation is used to calculate MPC fractions (Mi).

Ci Mi ~

MPCi where:

Mi = MPC fraction of radionuclide i.

C~ ~ concentration of radionuclide i in the radwaste tank, pCi/ml.

MPCi = MPC of radionuclide i as specified in Control 1.2.1.1, pCi/ml.

The sum of the ratios (R) will be calculated by the following relationship:

R= g Mi where:

R ~ the sum of the ratios.

i Mi ~ MPC fraction from equation 6.1.

6.1.2 Release Flow Rate Calculations The sum of the ratios at the diffuser pipes must be c 1 due to the releases from the above source. The following relationship will assure this criterion is met:

(R-1) ( F where:

f ~ the effluent flow rate (gallons/minute) before dilution.

R ~ the sum of the ratios as determined by Equation 6.2.

F ~ minimum dilution flow rate for prerelease analysis.

The allowable release rate is calculated before each release and the release rate is continuously monitored during the release so that the MPC limit is not exceeded.

RETS Manual Revision 9 Page 104 6.1.3 Post-release Anal sis A post-release analysis vill be done using actual release data to ensure that the limits specified in Control 1.2.1.1 vere not exceeded.

A composite list of concentrations (Ci) by isotope, vill be used vith actual liquid radvaste (f) and dilution (F) flow rates (or volumes) during the release. The data vill be substituted into Equations 6.1, 6.2 and 6.3 to demonstrate compliance with the limits in Control 1.2.1.1. This data and setpoints vill be recorded in auditable records by plant personnel.

RETS Manual Revision 9 Page 105 Alarm/trip setpoxnts for each liquid monitor will be established and set such that Equation 6.3 is satisfied. The locations and identification numbers for each liquid effluent radiation detector are shown in Figures 6.1 and 6.2. This section of the ODCM describes the methodology that will be used to determine allowable values. The allowable values are then used to determine the physical settings on the monitors. The physical settings are calculated in the applicable Scaling and Setpoint Documents 6.2.1 Radwaste Dischar e Monitor The allowable value for the radwaste discharge monitor (RM-90-130), shown in Figures 6.1 and 6.2, vill be established using the methodology below.

The alarm/trip allowable value will be set such that Equation 6.3 is satisfied. The trip allowable value for the monitor, which will automatically isolate the release, is set at less than or equal to the limit in Control 1.2.1.1. The alarm allowable value is set at 50K of the trip allowable value.

The maximum activity concentration of liauid radwaste that can be discharged into a Condenser Cooling Viater (CCV) condui. can be calculated as:

(MPCimi ) F Ac) f 1

where A "- maximum batch activity concentration, pCi/ml MPCi ~ Maximum Permissible Concentration, from 10 CFR 20 Appendix B for nuclide i, pCi/ml.

~ CCW dilution water flow rate, gpm.

= maximum discharge flow rate, gpm 1 The maximum activity concentration is based on a selected isotopic mixture so that an allowable value can be calculated. The selected isotopic mixture will be documented in TI 45. If the actual batch MPC is less restrictive than the MPC for the selected isotopic mixture, then the actual activity concentration may be higher than the calculated maximum activity concentration.

828o

RETS Manual Revision 9 Page 106 The monitor isolation allowable value, in cps, for releases to the CCW discharge conduit is calculated using the following equation'.

Releases can be simultaneously discharged to multiple CCW discharge conduits. If releases are routed to more than one CCW discharge conduit, the allowable activity concentration and hence the corresponding allowable value may be increased based on an increase in dilution flow.

6.2.2 Raw Coolin Water and Residual Heat Removal Service Water Monitors The allowable value for the Raw Cooling Water (RCW) monitors and the Residual Heat Removal Service Water (RHRSW) monitors (RN-90-132 and RM-90-133,134 respectively), shown in Figure 6.1, will be established using the methodology below. The alarm/trip allowable values will be set such that Equation 6.3 is satisfied. The allowable values for these monitors, which will alarm in the control room, are based on the 10 CFR 20 Appendix B concentration limits. These allowable values are also based on a selected isotopic mixture.

RETS Manual Revision 9 Page 107 6 ~ 3 CUMULATIVE LI UID EFFLUENT DOSE CALCULATION 6.3.1 Monthl Anal sis Principal radionuclides will be used to conservatively estimate the monthly contribution to the cumulative dose. If the projected dose calculated by this monthly method exceeds the monthly fraction of the annual limits in Control 1.2.1.2, then the methodology in Section 6.6 will be implemented.

The 20 nuclides listed below, based on operational source terms, contribute more than 95 percent of the total estimated dose to the total body and the most critical organ for both the water and fish ingestion pathways. The organs considered for both water ingestion and fish ingestion are the gastrointestinal tract (GIT), bone, thyroid and liver.

H-3 Fe-59 Sr-90 I-131 Na-24 Co-58 Zr/Nb-95 I-133 Cr-51 Co-60 Mo/Tc-99m C5-134 Mn-54 Zn-65 Ag-110m Cs-136 Fe-55 Sr-89 Sb-124 C5-137 A conservative calculation of the monthly dose will be done according to tne following procedure. First, the monthly operating repor. contain'ng the release data will be obtained and the activities reported (if any) for each of the above 20 radionuclides will be noted. This information will then be used in the following calculations.

RETS Manual Revision 9 Page 108 6.3.1.1 Water In estion The dose to an individual from ingestion of water is described by the following equation.

20 Djk = ~~ p i=1 (DFL)ijk ik where:

Djk = dose for the jth organ and the kth age group from the 20 radionuclides, mrem.

DFLijk ~ ingestion dose comnitment factor for the ith radionuclide for the jth organ for the kth age group, mrem/pCi (Table 6.4)

Iik ~ monthly activity ingested of the ith radionuclide by the kth age group, Ci.

The activity ingested due to drinking water, Iik, is described by:

103 Ai Uwa (1/12) where:

103 = conversion factor, ml/L.

Ai = activity released of ith radionuclide during the month, Ci.

RETS Manual Revision 9 Page 109 The dose to an individual from the consumption of fish is described by Equation 6.4.. In this case, the activity ingested of the ith radionuclide due to eating fish (Iik) is described by 103 Ai Bi Ufa (1/12)

6.3.1.4 Monthl Summa To obtain the total monthly dose to the total body, sum the total body dose from water ingestion, the total body dose from fish ingestion, and the recreation dose. This value will be compared to the limit for total body dose. To obtain the total monthly dose to the maximum organ, sum the maximum organ dose from water ingestion, the maximum organ dose from fish ingestion, and the recreation dose. This value will be compared to the limit for maximum organ dose. Calendar quarter and calendar year doses are first estimated by summing the doses calculated for each month in that year. However, if the annual doses determined in this manner exceed or approach the specification limits, doses calculated for previous quarters wi'th the methodology of ODCM Section 6.6 will be used instead of those quarterly doses estimated by summing monthly results. An annual check will be made to ensure that the monthly dose estimates account for at least 95 percent of the dose calculated by the method described in ODCM Section 6.6. If less than 95 percent of the dose has been estimated, either a new list of principal isotopes wi11 be prepared or. a new correction factor will be used. The latter option will not be used if less than 90 percent of the total dose is predicted.

RETS Manual Revision 9 Page 110 6.3.1.3 Recreation For the recreation dose calculation, the total dose is estimated based on a calculation of the shoreline dose for Co-58, Co-60, Cs-134, and Cs-137. The shoreline dose due to these four nuclides is expected to contribute over 95 percent of the total recreation dose. The total body and maximum organ dose to an individual via the shoreline recreation pathway are assumed to be equal. The recreation dose is described by the following equation:

4 1012 Dz ig 1 42 Dpi 4 where:

Dr ~ recreation dose from plant releases, mrem.

1012 ~ conversion factor, pCi/Ci.

0.95 ~ conservative correction factor for considering only 4 radionuclides.

42 ~ assumed monthly exposure time for maximum individual, hours DFGi = dose coamitment factor for standing on contaminated ground for the ith radionuclide, mrem/hr per pCi/m2 (Table 6.6).

concentration of ith radionuclide in shoreline sediment, Ci/m , as by the following equation (based on equation A-5 in 2'escribed Regulatory Guide 1.109).

~ 103 6 ~ 94E&4 100 RHLi W[1~(-'hitb] Ci (6.10) where.'03

= conversion factor, ml/L.

6.94E-04 ~ conversion factor, d/min.

RHLi ~ radiological half-life of the ith radioisotope, minutes (Table 1.11).

100 = conversion factor, L/Kg-hr (defined in Regulatory Guide 1.109).

W = shoreline width factor (Table 6.3).

X1 = decay constant of the ith radionuclide, sec (Table 1.11).

tb = buildup time in sediment, seconds (Table 6.3)

C i = concentration of ith radionuclide in the Tennessee River, Ci/ml.

Ai/{F d 7.34E+10) where:

A1. = activity released of ith radionuclide during the month, Ci/month.

F -" average river flow for the month, cfs.

d ~ fraction of river flow available for dilution, 0.30.

7.34E+10 = conversion from cfs to ml/month.

RETS Manual Revision 9 Page 140 7.0 GASEOUS EFFLUENTS RELEASE POINTS DESCRIPTION There are eleven monitored discharge points at BFN: a Reactor Building exhaust for each unit, the Radwaste Building Exhaust, two sets of Turbine Deck Roof Fans for each unit, and the Stack. The Reactor and Radwaste Exhausts exit the plant on the roof of the reactor building.

The Reactor Building Exhausts include exhaust from the refuel floor of the reactor buildings, exhaust from the Primary Containment Purge System, and exhaust from the turbine buildings. These discharge points are moni.tored by radiation monitors 1-,2-,3-RM-90-250.

The Radwaste Building Exhaust includes exhaust from the common radwaste building. This discharge point is monitored by radiation monitor RM-90-252.

There are nine roof fans on the roof of each unit's turbine building to provide building ventilation. These are generally used in the warmer months to control building temperature. For each unit, there are two radiation monitors. One of these monitors the exhaust through four of the fans (1-,2-RM-90-249 and 3-RM-90-251). The other monitors the exhaust through the remaining five fans (1-,2-RM-90-251 and 3-RM-90-249) ~

The common 600 foot plant stack receives the Condenser Offgas exhaust, the Filter Cubicle exhaust, the Steam Packing and Mechanical Vacuum exhaust, and the Standby Gas Treatment System (SBGTS) exhaust. The stack effluents are monitored by radiation monitors RM-90-147 and 148.

Figures 7.1 and 7.2 show the Offgas System, the Standby Gas Treatment System and normal building ventilation with effluent monitor locations.

RETS Manual Revision 9 Page 141 7.1 RELEASE RATE LIMIT METHODOLOGY A dose rate {DTB, DS, or DTH) is calculated based on the design objective source term mix used in the licensing of the plant. Dose rates are determined for {1) noble gases and (2) iodines and particulates as described in Section 7.3.

The dose rate limits of interest are:

Total Body = 500 mrem/yr Skin ~ 3000 mrem/yr Maximum Organ ~ 1500 mzem/yr These limits are divided by the corresponding calculated dose rates described above:

Total Body Dose Rate Limit RTB(vent or stack) = ven or s ac Skin Dose Rate Limit RS(vent or stack) = ven or s ac )

Maximum Organ Dose Rate Limit RTH(vent or stack) =

These ratios represent how far above or below the guidelines the dose rate calculations were.

A total release rate, Q, for each nuclide type {noble gas or iodine/particulate) and release point (building vent or stack) is calculated, using the source term data in Table 7.2. Thus, four total release rates are calculated:

Qngv ~ Total noble gas release rate from building exhaust vents, Ci/s.

Qngs ~ Total noble gas release rate from main stack, Ci/s.

ipv ~ Total iodine and particulate release rate from building exhaust vents, Ci/s.

Qips ~ Total iodine and particulate release rate from main stack, Ci/s.

To obtain a release rate limit, r, for each nuclide type and release point, the total release rate, Q, for that nuclide type and release point is multiplied by the corresponding ratio, R:

RETS Manual Revision 9 Page 144 7.2 GASEOUS EFFLUENT MONITOR INSTRUMENT SETPOINTS 7.2.1 Alarm/Tri Set pints Contxol 1.1:2 requires gaseous effluent monitors to have alarm/trip setpoints to ensure that the above dose rates are not exceeded. This section of the ODCM describes the methodology that will be used to determine these allowable values which are used to calculate setpoints. Figures 7.1 and 7.2 show the Offgas System, the Standby Gas Treatment System and normal building ventilation with effluent monitor locations.

The methodology for determining alarm/trip allowable values is divided into two major parts. The first consists of backcalculating from a dose rate to a release rate limit, in pCi/s, for each nuclide and release point. The methodology for the calculation of these release rate limits is given in Section 7.1. The second consists of using the release rate limits to determine the allowable values which are used to calculate the physical

~

settings on the monitors. The methodology for the calculation of the allowable values is given below. The monitor setpoints are calculated in the applicable Scaling and Setpoint Document.

7.2.2 Allowable Values To determine allowable values for gaseous effluent monitors, shown in Figures 7.1 and 7.2, the noble gas release rate limits are used.

The allowable values are calculated using the following equation r f A Allowable Value < + B

~here r release rate limit for stack or ground level, pCi/sec. The release rate limits used for the allowab1.e value calculation are 1.44E+07 pCi/sec for the stack and 1.50E+05 pCi/sec for the building vents.

fraction of the limits r which is allowed for the release mode (elevated or ground level).

NOTE: The sum of the f values for elevated and ground levels must be less than or equal to 1. This lowers the limits to ensure that the site dose rate limit vill not be exceeded if both the stack and the ground level release rate limits were reached simultaneously.

allocation factor. This is the portion of the release rate limit r which is assigned to the release point under consideration. This ensures that the ground level release rate limit will not be exceeded if all building vents were to reach their limit simultaneously. This is equal to 1 for the stack. The building vent release rate limit is divided among the ten vents based on the flow rates.

RETS Manual Revision 9 Page 146 7.3 GASEOUS EFFLUENTS DOSE RATES 7.3.1 Noble Gas Dose Rates Dose rates are calculated for total body and skin, due to submersion within a cloud of noble gases, using a semi-infinite cloud model. The use of a finite cloud model would result in calculated doses of 0 to 10 percent higher than those calculations using the semi-infinite cloud model for Browns Ferry Nuclear Plant (BFN). The dose rates are evaluated at the offsite locations with the highest expected concentrations, i.e.,

the nearest SITE BOUNDARY points in each sector (from Table 7.1) and at other locations expected to be the maximum exposure points.

The noble gas radionuclide mix used in this calculation is based on the design objective source term given in Table 7.2. Dispersion of the released radioactivity is handled as described in Section 7.9 using historical annual 'average meteorological data given in Table 7.3. No credit is taken for shielding by residence.

To calculate the noble gas dose rate from radiological effluents discharged from a given release point for any one of the potential maximum-exposure points, the equations given in Section 7.7.1 are used.

The total body and skin dose rate calculations are repeated for each release point. Dose rates for releases from all building vents are summed. The maximum stack and building vent total body and skin dose rates will be used to determine release rate limits.

RETS Manual Revision 9 Page 147 7' ' I 131 I-133 Tritium and all Radionuclides in Particulate Form with Half-lives of Greater than 8 da s - Or an Dose Rate Dose rates are calculated for the critical organ, thyroid, of the critical age group, infant. Pathways considered are inhalation, ground contamination and milk ingestion. The dose rates're evaluated at the offsite locations with the highest expected concentrations, i.e., the nearest SITE BOUNDARY points in each of the 16 sectors (from Table 7.1) and at other locations expected to be the maximum exposure points. This calculation assumes that a (hypothetical) cow is at each of these locations. These cows are assumed, conservatively, to obtain 100 percent of their food from pasture grass.

The inhalation, ground contamination, and milk ingestion dose rates (in mrem/year) for the selected organ (thyroid) and age group (infant) are calculated using Equation 7.9 as described in Section 7.6.2. For determining the total thyroid dose rate from iodines and particulates:

DTH = DTHI + DTBG + DTHM (7.1) where:

~ total thyroid dose rate, mrem/yr.

DTHZ = thyroid dose rate due to inhalation, mrem/yr.

DTBG = total body dose rate due to ground contamination, mrem/yr. The thyroid dose rate is assumed to be equal to the total body dose rate for this pathway.

DTHM = thyroid dose rate due to pasture grass-cow-milk ingestion, mrem/yr.

The iodine and particulate dose rates are calculated for the design objective source term given in Table 7.2. The above dose rate calculation is repeated for each release point. Dose rates for releases from all building vents are summed. The maximum stack and building vent thyroid dose rates will be used to determine release rate limits.

Because only these nuclides are considered, the dose is divided by'.9, to account for a possible 10 percent contribution of dose from other nuclides.

The dispersion factor used will be the highest annual-average y/Q based on 1977-1979 meteorological data (Table 7.3).

Methodology for this analysis is that which is described below, using the quarterly release values reported by the plant personnel. For iodine releases, it will be assumed that half the iodines released are organic iodipes, which contribute only to the inhalation dose. All real pathways and receptor locations (as identified in the most recent land use survey) are considered. In addition, actual meteorological data representative of each corresponding calendar quarter will be used to calculate dispersion factors as described in Section 7.9. Stack releases will be considered elevated releases.

Radwaste and reactor building releases will be considered split-level releases. Turbine building releases will be treated as ground level.

7.7.1 Noble Gas Dose All measured radionuclides are used to calculate gamma and beta air doses. The dose is evaluated at the nearest SITE BOUNDARY point in each sector and at other locations expected to be maximum exposure points using a semi-infinite cloud model. The use of a finite cloud model would result in calculated doses of 0 to 10 percent 'higher than those calculations using the semi-infinite cloud model for BFN.

Radioactive decay is considered in this calculation. The quarterly release is averaged over one year to obtain an average release rate.

RE S .'lanual Revision 9 Page 160 7.7.3 Po ulation Doses For determining population doses to the 50-mile population around the plant, each compass sector is broken down into elements. These elements are defined in Table 7.5. For each of these sector elements, an average dose is cal'culated, and then multiplied by the population in that sector element. Dispersion factors are calculated for the midpoint of each sector element (see Table 7.5). For population doses resulting from ingestion, it is conservatively assumed that all food eaten by the average individual is grown locally.

The general equation used for calculating the population dose in a given sector element is:

Dosepop P RATIOp

• POPN

• AGE

• 0 F 001

• DOSEP (7.10)

P where RATIOP ratio of average to maximum dose for pathway P. (Average ingestion rates are obtained from Regulatory Guide 1.109, Table E-4.)

= 0.5 for submersion and ground exposure pathways, a shielding/occupancy factor.

= 1.0 for the inhalation pathway.

= 0.515, 0.515, 0.5, and 0.355 for milk, for infant, child, teen and adult, respectively. (It is assumed that the ratio of average to maximum infant milk ingestion rates is the same as that for child.)

= 1.0, 0.90, 0.91, 0.86 for beef ingestion, for infant, child, teen and adult, respectively.

= 1.0, 0.38, 0.38, 0.37 for vegetable ingestion, for infant, child, teen and adult, respectively. (It is assumed that the average individual eats no fresh vegetables, only stored vegetables.)

POPN = the population of the sector element, persons (Table 7.6).

AGE = fraction of the population belonging to each age group.

= 0,015, 0.168, 0.153, 0.665 for infant, child, teen and adult, respectively (fractions taken from NUREG/CR-1004, Table 3.39).

0.001 = conversion from mrem to rem.

DOSEp the dose for pathway P to the maximum individual at the location under consideration, mrem. For ingestion pathways, this dose is multiplied by an average decay correction to account for decay as the food is moved through the food distribution cycle. This average decay correction, ADC, is defined as:

828o

RETS Manual Revision 9 Page 161 ADC = exp(-Kit), for milk and vegetables, where decay constant for nuclide i, seconds.

= distribution time for food product under consideration (from Regulatory Guide 2.109, Table D-l).

= 1.21E+06 seconds (14 days) for vegetables.

= 3.46E+05 seconds (4 days) for milk.

exP(-'hit) Kitch for meat, 1 exp(-X 1 cb) where Xi = decay constant for nuclide i, seconds.

= additional distribution time for meat, over and above the time for slaughter to consumption described in Section 7.8.3, 7 days (from Regulatory Guide 1.109, Table D-2).

= time to consume a whole beef, as described in Section 7.8.3.

For beef ingestion, the additional factors in the calculation of ADC negate the integration of the dose term over the period during which a whole beef is consumed, for the calculation of population dose. This assumes that the maximum individual freezes and eats a whole beef, but the average individual buys smaller portions at a time.

Population doses are summed over all sector elements to obtain a total population dose for the 50-mile population.

Meteorological data for ground level releases consist of windspeed and direction measurements at 10m and temperature measurements of 10m and 45 m.

Hourly average meteorological data for the ground level portion of a split level release consist of wind speeds and directions measured at the 10m level and temperature measurements at 10m and 45m. The elevated portion of the split level release uses wind speeds and directions measured at the 46m level and temperature measurements at 45m and 90m.

Raw meteorological data for the elevated releases consist of windspeed and directions measured at 93m. Stability class D is assumed to persist during the entire period for elevated releases, except for the dose calculations described in Section 7.7 when all stability classes will be used to evaluate the elevated results.

Meteorological data are expressed as a joint-frequency distribution of wind speed, wind direction, and atmospheric stability for each release level (ground, split and elevated). The joint-frequency distributions which represen the historical meteorological data for the period January 1977 to December 1979 are given in Table 7.3.

RETS manual Revision 9 Page 178 7.9.4 Effective Release Hei ht For effluents exhausted from release points that are higher than twice the height of adjacent structures (elevated releases) the effective release height is determined by the following equation, consistent with Regulatory Guide 1.111 he = hs + hpr ht.,.c where:

c = downwash correction factor for low relative exit velocity, 3(1.5-Wo/u)d, where Wo = the vertical plume exit velocity, m/s.

u = mean wind speed at the height of the release, m/s.

d = inside diameter of the release point, m.

NOTE: If c is less than zero, it is set equal to zero.

hpr = plume rise above the release point, m.

hs = physical height of release point, m.

ht = maximum terrain height between release point and receptor location, m.

For effluents released from points less than the height of adjacent structures, a ground level release is assumed (he = 0).

For effluents released from points at the level of or above adjacent structures, bu't lower than elevated release points, releases are treated as follows:

Case 1 elevated if Wo/u ) 5.

Case 2 ground level (he = 0) if Wo/u l.

Case 3 split level if 1 < wo/u < 5.

Under Case 3 a split level dispersion approach is implemented using a model that requires for each release point two JFDs, one for elevated releases and one for ground level releases. The summation of the elevated and ground level JFDs account for the total period of record.

Releases are considered to be elevated 100(1-Et) percent of the time and ground level 100 Et percent of the time where the entrainment coefficient, Et, is defined by Et = 2 58 1 58{Wo/u) for 1 < Wo/u < 1.5 Et = 0' 0'06{Wo/u) for 1.5 < Wo/u < 5 828o

0 RETS Manual Revision 9 Page 226 8.0 TOTAL DOSE To determine compliance with 40 CFR 190, the annual dose contributions to the maximum individual from BFN radioactive effluents and all other nearby uranium fuel cycle sources will be considered. The annual dose to the maximum individual will be conservatively'stimated by: first, suaaaing the total body air submersion dose, and the critical organ dose (except thyroid) from gaseous effluents; the total body dose, and critical organ dose (except thyroid) from liquid effluents for each quarter calculated in accordance with Sections 6.6 and 7.7. Then to this sum for each quarter is added any identifiable increase in direct radiation dose levels attributable to the plant as determined by the environmental monitoring program outlined in Section 9.0. These quarterly sums are then conservatively suaxned for the four calendar quarters to estimate the maximum individual dose for the year. This dose is compared to the limit in Control 3'.2.3, i.e., 25 mrem per year to the total body or any organ (except thyroid), to determine compliance.

The total annual thyroid dose to the maximum individual will be conservatively estimated in the following manner. For each calendar quarter, a total dose will be obtained by summing the total body gaseous submersion dose, the gaseous thyroid dose, the liquid total body dose, and the liquid thyroid dose. To this sum for each quarter is added any identifiable increase in direct radiation dose levels attributable to the plant as determined by the environmental monitoring program outlined in Section 9.0. These quarterly sums are then added together to estimate the maximum individual thyroid dose for the year. This dose is compared to the limit in Control 3.2.3, i.e., 75 mrem per year to determine compliance.

RETS Manual Revision 9 Page 227 SECTION 9.0 ENVIRONMENTAL MONITORING PROGRAM 828o

RETS Manual Revision 9 Page 228 9.1 MONITORING PROGRAM DESCRIPTION An environmental radiological monitoring program as described in Tables 9.1, 9.2 and 9.3 and in Figures 9.1, 9.2, and 9.3 shall be conducted. Results of this program shall be reported in accordance with ODCM Administrative Control 5.1.

The atmospheric environmental radiological monitoring program shall consist of 10 monitoring stations from which samples of air particulates and radioiodine shall be collected.

The terrestrial monitoring program shall consist of the collection of milk, soil, drinking water, and food crops. In addition, direct gamma radiation levels will be measured at 40 or more locations in the vicinity of the plant.

The reservoir sampling program shall consist of the collection of samples of surface water, sediment, and fish.

9.2 DETECTION CAPABILITIES Analytical techniques shall be such that the detection capabilities listed in Table 2.3-2 are achieved.

9.3 LAND USE CENSUS A land use survey shall be conducted in accordance with the requirements in Control 1.3.2. The results of the survey shall be reported in the Annual Radiological Environmental Operating Report.

9.4 INTERLABORATORY COMPARISON PROGRAM Analyses shall be performed on radioactive materials supplied as part of an Interlaboratory Comparison Program which has been approved by the NRC. A summary of the results obtained in the intercomparison shall be included in the Annual Radiological Environmental Operating Report (or the EPA program code designation may be provided).

If analyses are not performed as required corrective actions taken to prevent, a recurrence shall be reported in the Annual Radiological Environmental Operating Report.

4. 0 WASTE CHARACTERISTICS 4.1 Waste Streams Three general waste streams applicable to this PCP have been identified for Browns Ferry. These are the Condensate Waste Phase Separator (CWPS), Reactor Water Cleanup Phase Separator (RWCU), and Dry Active waste (DAW). Other waste streams may be established based upon plant operational needs.

CWPS is fed by several waste sub-streams, including the Equipment Drain, Chemical Waste, Floor Drain, Fuel Pool Cooling, and Condensate systems.

RWCU is fed by Reactor Water Cleanup only.

DAW is used for wastes generated within the regulated areas of the reactor buildings and turbine buildings which cannot be appropriately attributed to either RWCU or CWPS. DAW normally includes paper, plastic, wood, metal and other such material generated as a result of the operation and maintenance of the plant.

4.2 Waste Form Wet solid radioactive wastes consist of bead resins, filter aids (such as activated charcoals or carbons), powdered resins, and slurries or sludges.

Wastes which may require solidification may include, but are not limited to, liquids which cannot be processed using installed plant systems, oils, chemicals, aqueous filter media, and decontamination wastes.

Wastes are processed as appropriate to ensure that the minimum physical characteristics required by 10 CFR and disposal site criteria are met. All Class B and Class C waste is stabilized. On occasion, Class A waste (such as aqueous filter media with a concentration > 1 uCi/cc of isotopes with half-lives > 5 years) may be solidified or stabilized by BFN. Class A liquid wastes may be either solidified or packaged in sufficient absorbent material to absorb twice the volume of the liquid, as appropriate to the specific disposal site criteria or license requirements.

Tests are performed on those wastes which are solidified to ensure the adequacy of the solidification agent and procedural technique.

These tests are made on a minimum of three samples from each waste batch to be solidified.

IV-4 828o

RETS Manual Revision 9 Page 243 4.3 Waste Classification Scaling factors which relate hard-to-measure isotopes to key isotopes commonly measured at BFN have been developed for each waste stream. These scaling factors are used in the classification of the waste for disposal. Scaling factors may be developed on an as needed basis depending on changing plant operational conditions. Updates are performed at least every two years for waste normally considered to be Class A, on an annual basis for other wastes, or when the scaling factors are considered to be high or low by a factor of ten.

Batch samples, separator samples, or sludge samples are taken fox radiochemical analysis prior to processing the waste for shipment.

DAW samples or area smears are taken to establish the relative percent abundance of isotopes for, the DAW waste stream.

Materials which do not fit within the scope of existing scaling factors and waste streams are sampled. The samples are sent offsite for analysis and development of scaling factors prior to disposal of the materials.

5.0 SHIPMENT MANIFESTS 5.1 Manifest Pre aration Manifests axe prepared for each shipment of radioactive waste for disposal. Programmatic guidance for manifest preparation is provided through the TVA Office of Nuclear Power, Radwaste Branch to ensure that all 10 CFR and 49 CFR criteria are met. Procedures for manifest preparation implement the specific requirements of 10 CFR 20.311, Transfer for Disposal and Manifests.

5. 2 Manifest Trackin Acknowledgment of receipt for each shipment to a disposal site is sent to BFN Radwaste Group by the disposal site. Shipments for which acknowledgment is not received within the time limits allowed in 10 CFR 20.311 are traced by the TVA Office of Nuclear Power, Radwaste Branch.

RETS Manual Revision 9 Page 244

6. 0 ADMINISTRATIVE CONTROLS 6.1 Procedures and Surveillance Detailed procedures are written and maintained by BFN which cover plant process systems, waste packaging, and shipment requirements.

Surveillance Instructions are used to verify that plant Technical Specifications for waste processing are met.

Programmatic guidance is provided through the TVA Office of Nuclear Power, Radwaste Branch. The Radwaste Branch maintains the Radioactive Material Shipment Manual and the Package Quality Assurance Program (for packages licensed under 10 CFR 71).

6.2 ualit Assurance/ ualit Control Quality assurance audits are conducted by the BFN site Quality Assurance organisation, and by the TVA Division of Nuclear Quality Assurance (DNQA). Audit findings are reviewed by BFN management, ensuring prompt corrective actions when needed.

Quality control measures include quarterly tests of the resin dewatering system performed by BFN personnel upon actual dewatered High Integrity Containers (HICs) or liners, site review of all radwaste vendor procedures before use, and second party verification by BFN personnel of end points or acceptance criteria in vendor procedures. Quality control of solidification methods is performed through controlled testing of a minimum of three samples from each batch to be solidified. Proportions of solidification agents are established which meet the standards for waste form and free liquid criteria.

6. 3 ~Tra itin Personnel involved in processing radioactive waste for shipment are trained in site procedures, regulatory requirements, and disposal site criteria. Training and retraining sessions are held when needed to support operations. Retraining is required on an annual basis to maintain qualification. Personnel found not complying with procedures may have their qualifications revoked by the Radwaste Group Supervisor, if deemed necessary. Qualifications may be reestablished through completion of retraining, and approval of the Radwaste Group Supervisor.

IV-6 828o

RETS Manual Revision 9 Page 245 6.4 Retention of Records Records are maintained to furnish documentation of items or activities affecting quality. Quality assurance records are stored in accordance with plant instructions and the TVA Nuclear Quality Assurance Manual.

RETS Manual Revision 9 Page 248 ENCLOSURE Dewatering is conducted at BFN using plant equipment and plant personnel.

Chem-Nuclear Systems, Inc., (CNSI) high-integrity containers and the CNSI dewatering procedures are used.

l. EKCEPTIONS OR DEVIATIONS TAKEN TO CNSI TOPICAL REPORT DATED DECEMBER 1983.

BFN dewaters powdered resin, filter media, and mixtures of powdered resin with small quantities of bead resin (normally less than 10 percent bead resin) using Chem-Nuclear Procedure FO-OP-022, "Ecodex Precoat/Powdex/Solka-Floe/Diatomaceous Earth Dewatering Procedure for CNSI 14-195 or Small Liners." The dewatering system was fabricated by TVA to meet the equipment specifications in FO-OP-022. The TVA dewatering system differs from the Chem-Nuclear system in that:

(a) TVA's system has no off-gas collector. The high integrity containers are open to the waste packaging room air during filling and dewatering. Air from this room is normally discharged through the Radwaste Building ventilation system. This air then flows through a HEPA filter and is released through a monitored release point on the Reactor Building roof.

(b) The valves on the pump suction manifold are manually operated. The system is not operated remotely. However, the high integrity containers are enclosed behind a shielded wall or inside a shielded cask during filling and dewatering to keep radiation levels in the vicinity of the system near background.

(c) There are no vacuum gauges at each inlet connection. A single vacuum gauge is provided at the flush inlet connection to the manifold. This vacuum gauge will indicate a break in vacuum in any active (not isolated) filter set. Loss of vacuum normally occurs in sequence from the top to the bottom set of filters. When vacuum breaks at a given filter level, that level is isolated. Therefore, vacuum is monitored continually for all active filter sets.

(d) There is no automatic level control or level indicating instrument in the TVA dewatering system. Level is determined by visual observations.

TVA has conducted tests which conclude that mixtures of bead and powdered resin, in proportions of up to 50-percent bead, can be adequately dewatered using a modified procedure for dewatering powdered resin.

These tests were conducted using TVA-fabricated steel liners with dewatering internals similar to those found in the Chem-Nuclear high-integrity containers and a dewatering pump which is inferior to that 828o

0 RETS Manual Revision 9 Page 249 specified in FO-OP&22, in that it is limited to a vacuum of 13" Hg and has a flow rate of six SCFM. In addition, the dewatering procedure used for the tests called for only four hours of bulk dewatering, as opposed to three eight-hour pumping cycles specified in FO-OP-022. The conditions of the test were clearly less conducive to proper dewatering than those specified in FO-OP-022 (this equipment and procedure is not used for normal operation). However, results show that adequate dewatering is guaranteed either by extending the dewatering time in the procedure or by applying an additional dewatering cycle at the end of the bulk dewatering process using a high flow rate (approximately 200 SCFM at 28" Hg) vacuum pump. TVA has modified FO-OP-022 to include two hours of additional dewatering with the 200 SCFM vacuum pump for all resin.

2. INTERFACES BETWEEN PLANT AND CNSI EQUIPMENT (a) The high-integrity container is filled with spent resin slurry through a one-inch flexible hose. Flow through the hose is controlled by way of a diaphragm-operated valve. The hose is connected to the high-integrity container with an Evertight quick disconnect fitting that has been modified for remote operation.

(b) The dewatering pump discharges through a one-inch flexible hose to the plant waste packaging drain header which leads to the waste package drain tank. The connection to the header is made by an OPW 633 D Kamlock quick disconnect fitting.

'(c) Radwaste compressed air is supplied through a flexible hose with Chicago connections to the air operated positive displacement pump.

(d) Demineralized water is provided by a flexible hose with Chicago connections to the flush-inlet valve on the dewatering pump suction manifold.

(e) The dewatering system is located inside the radwaste packaging room (see figure 1). Any leaks or spills will be contained inside this room by exterior doors which are closed during filling, and collected in radwaste floor drains. Failure of any of these resin processing components will not provide a pathway for radioactive materials into the environment or potable water supply.

3. LOCATION AND AMQNGEMENT OF DEWATERING SYSTEM IN PLANT See Figure 1.

IV-11 828o

RETS Manual Revision 9 Page 250 4~ WASTE CLASSIFICATION TO MEET 10 CFR 61.55 Radionuclide concentrations are determined by direct measurement.

Samples, or smears, as appropriate, of standard waste streams are sent offsite for analysis. An inferential measurement program is then established whereby concentrations of radioisotopes which cannot be readily measured are projected through ratioing to concentrations of similar behaving isotopes which can be readily measured.

RETS Manual Revision 9 Page 255 ENCLOSURE 1 Dewatering will be conducted at BFN using the Chem-Nuclear Systems, Inc.

(CNSI) Rapid Dewatering System (RDS-1000). CNSI high-integrity containers and/or steel liners and plant specific versions of CNSI Procedure FO-OP-032, "Setup and Operating Procedure for the RDS-1000 Unit" and CNSI Procedure F~P-035, "Setup and Operating Procedure for Dewatering Pre-Coat Media in a 21-300 Liner Using the RDS-1000" will be used.

I. EKCEPTIONS OR DEVIATIONS TAKEN TO CNSI TOPICAL REPORTS DW-11118&1-P-A AND RDS-25506-01-P TVA's system has no off-gas system connection available for interface with the RDS-1000. The rapid dewatering skid of the RDS-1000 system has a HEPA filter installed downstream of the safety relief valve and manual bypass valve. Liners will be vented through this HEPA filter to the waste packaging room. Air from this room is normally discharged through the radwaste building ventilation system. This air then flows through an installed HEPA filter before release through a monitored release point on the reactor building roof. Exterior doors from the waste packaging room are closed during liner filling and dewatering operations.

2. INTERFACES BETWEEN PLANT AND CNSI EQUIPMENT A. A plant connection stand (PCS) is provided as part of the RDS-1000 system. Its components are:

1. A remotely operated valve to control influent to the liner;

2. A diaphragm pump with connections to the liner fillhead for initial gross dewatering;

3. Manifolds for air and service water supplies to control elements and flushing systems.

B. Radwaste building compressed service air will be provided to the PCS at approximately 40 SCFM at 80 psig (+20, -10 psig) through a flexible hose. The connection to plant air and water is made via quick-disconnect fittings. The PCS connection to CNSI equipment is also a quick-disconnect fitting.

828o

RETS Manual Revision, 9 Page 256 C. Radwaste building service water (demineralized) will be provided to the PCS at approximately 25 gpm at 80 psig (+20 psig) through a flexible hose. Both connection points (plant and PCS) are equipped with quick-disconnect fittings.

D. The dewatering pump discharge is provided by a 1.5 inch flexible hose to the plant waste packaging drain header which leads to the waste package drain tank. The connection to the drain header is made by a 1-inch Kamlock quick-disconnect fitting. The dewatering pump connection is a 1.5 inch Kamlock quick-disconnect fitting. A 1 to 1.5-inch Kamlock adaptor will be used at the drain header.

E. The connection to the plant waste media line will be made either by a 1.5-inch 150 ANSI flat faced flange connection or by a flange connection to Kamlock quick-disconnect adaptor utilizing existing flexible hose. A waste isolation valve .will be installed downstream of this connection, providing local control by the CNSI operator over the flow of waste to the liners being filled. The waste isolation is controlled remotely, and is interlocked to close on high waste level, high-high level, decreasing air pressure, or loss of electrical power.

3. LOCATION AND ARRANGEMENT OF DEWATERING SYSTEM IN PLANT See Figure 1 The RDS-1000 system will be located inside the radwaste packaging room, elevation 565'. Any leaks or spills will be contained inside this room by exterior doors, which are closed during liner filling and dewatering operations. Any spillage will be collected in the radwaste floor drains.

Failure of any of these resin processing components will not provide a pathway for radioactive, materials into the environment or potable water supply.

IV-18 828o

RETS Manual Revision 9 Page 257

4. WASTE CLASSIFICATION TO MEET 10 CFR 61.55 Radionuclxde concentrations are determined by direct measurement. Samples or smears, as appropriate, of standard waste streams are sent offsite for analysis. An inferential measurement program is then established ~hereby concentrations of radioisotopes which cannot be readily measured are projected through ratioing to concentrations of similarly behaving isotopes which can be readily measured. Scaling factors are developed on a waste stream specific basis. Scaling factors are periodically reconfirmed through sampling and analysis. Computerized calculation of individual container isotopic contents is performed. Maintenance, testing, and independent verification of this program ascertain correct data manipulation. TVA QA audits of the vendor laboratory conducting the periodic sample analysis confirm quality practices at that location.

Procedural controls, corporate assessments of the radwaste program, periodic QA audits of the program, and management evaluation of audit findings ensure quality in the plant program.

5. DESCRIPTION OF WASTE CONTAINER High-integrity containers manufactured by CNSI are used for packaging resin. The following containers are used: 8-120,14-195, and 14-170.

They are discussed in a topical report dated December 1983 entitled, "Chem-Nuclear Systems, Inc., Topical Report Polyethylene High Integrity Containers CNSI-HIC-14571-01-NP." CNSI 21-300 steel liners are compatible with the dewatering system and may also be used.

6. CAPABILITY TO MEET 10 CFR 50 APPENDIX I This dewatering process does not cause any direct releases to the environment.

1. EXCEPTIONS OR DEVIATIONS TAKEN TO PACIFIC NUCLEAR TOPICAL REPORT TP-02-NP-A I

TVA's system has no off-gas connection available for connection to the Resin Drying System. The Resin Drying System blower skid contains a HEPA filter which removes airborne particulate matter from the container vent pathway during the container filling cycle and vents this air to the general area around the skid. This air is then discharged through the plant ventilation system. This air flows through an installed HEPA filter through a monitored release point prior to its release to the environment.

2. INTERFACES BETWEEN PLANT AND PACIFIC NUCLEAR SYSTEMS, INC EQUIPMENT A. Plant compressed service air will be supplied to the Resin Drying System at approximately 40 SCFM at 100 psi through a flexible hose.

B. Plant service water (demineralized) will be supplied to the Resin Drying System at approximately 25 gpm at 80 psi through a flexible hose.

C. The Resin Drying System will discharge the water removed from the high>>integrity container to the plant radwaste system through a flexible hose.

D. The connection to the waste transfer line is made via a high pressure flexible hose to the fillhead which is connected to the high-integrity container. A waste isolation valve provides the Pacific Nuclear System operator local control over the flow of waste to the liners. The waste transfer isolation is controlled remotely and the fillhead is interlock to close automatically on high waste level, or high fillhead pressure alarms.

3. LOCATION AND AR14NGEMENT OF DEWATERING SYSTEM IN PLANT The Resin Drying System will be located inside a permanent plant building. Any leaks or spills would be contained inside this building.

Safety Assessment for ODCM Revision (Revision 10 to RETS Manual)

A. Description This change adds text to the ODCM which duplicates text currently found in the BFN Technical Specifications. This change is a followup to ODCM Revision 9 which was made in anticipation of a T/S change to implement the NRC's Generic Letter 89-01. The Generic Letter recommended the relocation of all procedural details in the T/S dealing with radioactive gaseous and liquid effluents to the ODCM. A. review of Revision 9 against. the T/S change package showed that some of the text in the Bases section was omitted from the final ODCM package. Two paragraphs are being added to the bases for ODCM Control 1/2.3.2.2 Dose --Noble Gases describing the action to be taken if limits are exceeded and a mention of the required report to the NRC The text which is heing duplicated is done so verbena fram the T/S wording.

The review of the change also compared revision g of the ODCM to revision 'LQ]ayThis review indicated that several paragraphs/sections were

$ 7@

omitted during @Be reformatting process.

IRK+1 These include the section describing the equations for the calculation of dose rates (added on page 141), and the equations which must be met for all release rates out of the plant (added on page 143}.

The only systems potentially affected by a change to the ODCM will be the liquid and gaseous effluent and process monitoring systems described in the BFN FSAR. Since this revision does not change any calculational methodology, requirements, or processes, these systems it will not have any effect on References

3. BFN FSAR Section 7.12, "Process Radiation Monitoring."

4. BFN FSAR Chapter 9.0, "Radioactive Haste Control Systems.-

5. BFN FSAR Section 10.17'Process Sampling Systems."

6. NRC Generic Letter 89-01, "Implementation of Programmatic Controls for Radiological Effluent Technical Specifications in the Administrative Controls Section of the Technical Specifications and the relocation of procedural details of RETS to the Offsito Dose Calculation Manual or to the Process Control Program." (A02 890209 005).

B. Impact on Safety The ODCM contains the methodology used to calculate setpoints for gaseous and liquid effluent monitors. Since the revision only adds text to the ODCM which already appears in the T/S or appeared in the previous ODCM, it will in no way affect the methodology described in tho plant procedures; hence no setpoints will be changed due to this revision.

Safety Assessment for ODCM Revision (Revision 10 to RETS Manual)

B. Impact on Safety (continued)

Since there is no effect on setpoints for effluent monitors. and no other safety concerns are impacted by this revision. it may be concluded that the change is acceptable from a nuclear safety standpoint.

C. Potential Technical Specification (T/S) Impact This revision to the ODCM is in preparation of a proposed T/S revision which will implement the NRC's Generic Letter 89-01. The Generic Letter recommended the relocation of all Specifications dealing with radioactive gaseous and liquid effluents to the ODCM.

The text from the T/S has been duplicated in the ODCM verbatim. References between Tables, Figures Specifications and other documents were changed in order to ensure that the ODCM will be a self-contained document after the T/S revision.. Until the T/S change recommended by the Generic Letter is prepared and processed~ there will be no changes in any procedures or activities which implement the T/S. Since the ODCM revision simply duplicates T/S requirements and wording, the T/S it will not require a change to Since the additions to the ODCM duplicate the T/S wording, no processes or activities governed by the current Technical Specifications will be affected by this change. This change will, therefore, have no impact on the Technical Specifications.

D. Potential Safety Analysis Impact This ODCM revision places text in the ODCM which duplicates text found in T/S and the previous revision of the ODCM. It does not change any design characteristics, functional requirements, or methodology for dose calculations and setpoint calculations that are described in the FSAR. Any references in the FSAR to the T/S themselves will continue to be valid. as will references to the ODCM as the location for methodology for dose and setpoint calculations. Therefore, this revision will have no effect on the FSAR text.

This revision does not change any equipment. requirements, methodology. or descriptions of any of these nor does it change the way in which any requirements are implemented. All descriptions in the SAR will continue to be valid after this revision.

This ODCM revision will not require any new procedures or instructions or revisions to existing procedures or instructions.

RETS Manual Revision 10 0 aaszs Page 88 1/2.2 RADIOhCTIVE EFFLUENTS 1/2.2.2.2 DOSE - NOBLE GASES This requirement is provided to implement thc requirements of Section II.B, III.h, and IV.A of Appendix I, 10'CFR Part 50. The limits are the guides set forth in Section II.C of hppendix I.

The action to be taken for exceeding these limits provi.des the required operating flexibility and at the same tine implemeats the guides set forth in Section IV.h of Appendix I to assure that the releases of radioactive material in gaseous cfflucnts will be kept "as low as reasonably achievable." Section 7.0 calculational methods 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 an individual through appropriate pathways is unlikely to be substantially underestimated. Section 7.0 calculational methods for calculating the doses due to the actual release rates of the subject materials are consistent with the methodologies provided in NUREG/CR-1004, "h Statistical Analysis of Selected Parameters for Predicting Food Chain Transport and Internal Dose of Radionuclides." October 1979 and Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purposes of Evaluating Compliance with 10 CFR Part 50, "Appendix I," Revision 1, October 1977 and Regulatory Guide l.ill, "Methods for Estimating htmospheric Transport and Dispersion of Gaseous Effluents ia Routine Releases from Light-Mater Cooled Reactors," Revision 1, July 1977. These ODCM equations also provide for determining the air doses at the exclusioa area boundary are based upon the historical average atmospheric conditions. NUREG-0133 provides methods for dose calculations consistent with Regulatory Guides 1.109 and 1.111.

If these limits are exceeded, this section requires that a special report be prepared and submitted to explain violations of the limiting doses contained in the section above.

RETS Manual Revision 10 Page 94 DEFINITIONS This category shall include non~loyees of the licensee who are permitted to use portions of the site for recreational'ccupational'r other purposes not associated with plant functions. This category shall not include non-employees such as vending machine servicemen or postmen who, as part of their formal job function,.occasionally enter RESTRICTED AREAS.

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

also capable of performing their related support function(s).

3.0.G. PURGE PURGING PURGE or PURGING is the controlled process of discharging air or gas fr o m the p rimar y co ntainment to maintain temperature, pressure, humidity, concentration or other operating condition, in such a manner that replacement air or gas is required to purify the containment.

3.0.H. RATED POWER RATED POWER refers to operation at a reactor power of 3,293 MWt; this is also termed 100 percent power and is the maximum power level authorized by the operating license. Rated steam flow, rated coolant flow, rated neutron flux, and rated nuclear system pressure refer to the values of these parameters when the reactor is at rated power.

Design power, the power to which the safety analysis applies, corresponds to 3,440 MWt.

3.0.I. SITE BOUNDARY The SITE BOUNDARY shall be that line beyond which the land is not owned, leased, or otherwise controlled by TVA (see Figure 3.1).

3.0.J. SOURCE CHECK h SOURCE CHECK shall be the qualitative assessment of channel response when the channel sensor is exposed to a radioactive source or multiple of sources'890o

RETS Manual Revision 10 Page 142 h dose rate {DTB, DS, or DTH) is calculated based on the design objective source term mix used in the licensing of the plant. Dose rates are determined for (1) noble gases and (2) iodines and particulates as described below.

Total Bod Dose Rate The dose rate to the total body from nuclide i, DTBi in mrem/year, is calculated using the following equation:

( /Q) Qi DFBi where X/Q a relative concentration, s/m . Relative air concentrations are calculated for the land-site boundary in each of the sixteen sectors as described in Section 7.9.2 using the historical meteorological data for the period 1977-1979 given in Table 7.3.

Revision 11 Page 106 6.2 INSTRUMENT SETPOINTS Alarm/triP set P oints for each liquid monitor will be established and set such that Equation 6.3 is satisfied. The locations and identification numbers for each liquid effluent radiation detector are shown in Figures 6.1 and 6.2. This section of the ODCM describes the methodology that will be used to determine allowable values. The allowable values are then used to determine the physical settings on the monitors. The physical settings are calculated in the applicable Scaling and Setpoint Document.

6.2.1 Radwaste Dischar e Monitor The allowable value for the radwaste discharge monitor (RM-90-130), shown in Figures 6.1 and 6.2, will be established using the methodology below.

The alarm/trip allowable value will be set such that Equation 6.3 is satisfied. The trip allowable value for the monitor, which will automatically isolate the release, is set at less than or equal to the limit in Control 1.2.1.1. The alarm allowable value is set at 50K of the trip allowable value.

The maximum activity concentration of liquid radwaste that can be discharged can be calculated as:

1 A = F +

f*L f

MFi MPC.

where:

A maximum batch activity concentration, pCi/ml.

Mpci Maximum Permissible Concentration, from 10 CFR 20 Appendix B for nuclide i, pCi/ml.

weighting factor for nuclide i, defined as the fraction of the total concentration which is attributed to nuclide i.

dilution water flow rate, gpm.

maximum discharge flow rate, gpm.

The maximum activity concentration is based on a selected isotopic mixture so that an allowable value can be calculated. The selected isotopic mixture will be documented in TI 45. If the actual batch MPC is less restrictive than the MPC for the selected isotopic mixture, then the actual activity concentration may be higher than the calculated maximum activity concentration.
