l INTRODUCTION The Off-site Dose Calculation Manual (ODCM) is provide to support implementation of the Crystal River Unit 3 radiological effluent controls.

The ODCM is divided into two parts. Part I contains the specifications for liquid and gaseous radiological effluents and the radiological environmental monitoring program which were relocated from the Technical Specifications in accordance with the provisions of Generic Letter 89-01 issued by the NRC in January, 1989. Part II of the ODCM contains the calculational methods to be used in determining the dose to members of the public resulting from routine radioactive effluents released from Crystal River Unit 3. Part II also contains the methodology used to determine effluent monitor alarm / trip setpoints which assure that releases of radioactive materials remain within specified concentrations.

l The ODCM shall become effective after the review and approval of the Plant Review Committee and approval by the Director, Nuclear Plant Operations in accordance with Technical Specification Section 5.6.2.3. Changes to the ODCM shall be documented and records of reviews perforrad shall be retained. This documentation shall contain sufficient information to support the change (including analyses or evaluations), and a determination that the change will maintain the level of radioactive effluent control required by the regulations listed in Technical Specification and not adversely impact the accuracy or reliability of effluent, dose, or setpoint calculations.

Changes shall be submitted to the NRC in the form of a complete and legible copy of the entire ODCM as part of, or concurrent with, the Radioactive Effluent Release Report for the period of the report in which any change to the ODCM was made. Each change shall be identified by markings in the margin of the affected pages, clearly indicating the area of the page that was changed.

a. The LLD* is the smallest concentration of radioactive material in a sample that will be detected with 95% probability with 54 probability of falsely concluding that a blank observation represents a "real" signal.

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

LLD = 4.66s / (2.22x10'EVYe-1At)

Wheres LLD is the lower limit of detection as defined above (as microcurie per unit mass or volume),

s3 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),

2.22x10' is the number of disintegrations per minute per microcurie, Y is the fractional radiochemical yield (when applicable),

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

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

• The LLD is defined as an a prioti (before the fact) limit representing the capability of a measurement system and not as an A costeriori (after the fact) limit for a particular measurement.

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

c. To be representative of the. quantities and concentrations of radioactive materials in liquid effluents, samples shall be collected continuously in proportion to the rate of flow of the effluent stream. Prior to analyses, all samples taken for the composite shall be thoroughly mixed in order for the composite sample to be representative of the effluent release.

d. A batch release is the discharge of liquid wastes of a discrete volume.

Prior to sampling for analyses, each batch shall be isolated, and then thoroughly mixed to assure representative sampling.

e. A continuous release is the discharge of liquid wastes of a nondiscrete volume; e.g., from a volume or system that has an input flow during the continuous release.

f. The principal gamma emitters for which the LLD specification applies exclusively are the following radionuclides: Mn-54, Fe-59, co-58, Co-60, -

Zn-65, Mo-99, Cs-134, Cs-137, Co-141, and Co-144. This list does not mean that only these nuclides are to be detected and reported.

3.2 RADI0 ACTIVE GASEOUS EFFLUENT NONITORING INSTRUMENTATION BASIS l

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 are calculated in accordance with the procedures in the OFFSITE DOSE CALCULATION MANUAL (ODCM) to ensure that the alarm / trip will occur prior to exceeding a Site Boundary dose rate of 500 mrem / year to the total body. The OPERABILITY and use of this instrumentation is consistant with the requirements of General l

Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50.

3.3 LIOUID RADWASTE TREATMENT SYSTEN BASIS The requirement that these systems be used when specified provides assurance that the releases of radioactive materials in liquid effluents will be kept "as low as reasonably achievable" (ALARA).

This specification implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and the design objective given in Section II.D of Appendix I to 10 CFR Part 50. The specified limits governing the use of appropriate portions of the liquid radwaste treatment system were specified as a suitable fraction of the dose design objectives set forth in Section II.A of Appendix I, 10 CFR Part 50, for liquid effluents.

3.4 WASTE GAS SYSTEN BASIS l

The requirement that these systems be used when specified provides reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept "as low as is reasonable achievable" (ALARA). This specification implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix A ..; 10 CFR Part 50, and the design objectives given in Section II O of Appendix I to 10 CFR Part 50. The specified limits governin; t.ie ase of appropriate portions of the systems were specified as a suitable fraction of the dose design objectives set forth in Sections II.B and II.C of Appendix I, 10 CFR Part 50, for gaseous effluents.

3.5 LIOUID EFFLUFJfTS CONCENTRATION BASIS This specification is provided to ensure that the concentration of radioactive materials released in liquid waste effluents to UNRESTRICTED AREAS will be less than 10 times the effluent concentration limits (ECLs) specified in 10 CFR Part 20. This limitation provides additional assurance that the levels of radioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within the Section II.A design objectives of Appendix I, 10 CFR 50, to a HEMBER OF THE PUBIC. The concentration limit for Xe-133 was determined by calculating that amount of the isotope, which if present in water, would give a dose rate of 500 mrem /yr at the surface. Typically, over 90% of the noble gas released in liquid effluents at CR-3 is Xe-133. The concentration limit for all other dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radioisotope and its MPC in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication 2.

3.6 LIOUID EFFLUENTS DOSE BASIS This specification is provided to implement the requirements of Sections II.A. Ill-A and IV.A of Appendix I, 10 CFR Part 50. The Limiting Condition for Operation implements the guides set forth in Section II.A of Appendix I. The ACTION statement provides the I required operating flexibility and at that same time implements the guides set forth in Section IV.A of Appendix I to assure that the i releases of radioactive material in liquid effluents will be kept "as low as is reasonably achievable" (ALARA). The dose calculations in the OFFSITE DOSE CALCULATION MANUAL (ODCM) implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data, such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The equations specified in the OFFSITE DOSE CALCULATIONAL MANUAL (ODCM) for calculating the doses due to the actual release rates of radioactive materials in liquid effluents are conciatent with the methodology provided in Regulatory Guide 1.109, " Calculation of Annua) Doses to Man from Routine Releases of Reactor Ef fluents for the Puriose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.113, " Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I," April 1977.

3.7 GASEOUS EFFLUENTS DOSE RATE BASIS This specification is provided to ensure that the dose at any time at and beyond the SITE BOUNDARY from gaseous effluenta will be within the annual dose limits of 10 CFR Part 20, SS 20.1 - 20.602.

The annual dose limits are the doses associated with the concentrations of 10 CFR Part 20, SS 20.1 - 20.602, Appendix B, Table II, Column 1. These limits provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of a MEMBER OF THE PUBLIC, either within or outside the SITE BOUNDARY to annual average concentrations exceeding the limits specified in Appendix B, Table II of 10 CFR Part 20 (10 CFR Part 20.106(b)(1)). For a MEMBER OF THE PUBLIC who nay at time 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 gamma and beta dose rates above to a MEMBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal to 500 mrem / year to the total body or to less than or equal to 3000 mrem / year to the skin. These release rate limits also restrict, at all times, the corresponding thyroid dose rate above background to a child via the inhalation pathway to less than or equal to 1500 mrem / year.

-required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in gaseous effluents will be kept "as low as reasonably achievable" (ALARA). The Surveillance Requirements implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of a MEMBER OF THE PUBLIC thcough appropriate pathways is unlikely.to be substantially underestimated. The dose calculations established for calculating the doses due to the actual release rates of radioactive noble gases in gaseous effluents.are consistent with the methodology provided in Regulatory Guide 1.109,

" Calculational of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.111, " Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water Cooled Reactors," Revision 1, July 1977. The equations provided for determining the air doses at and beyond the SITE BOUNDARY are based upon the historical average atmospheric conditions.

3.9 GASEOUS EFFLUENTS DOSE I-131, TRITIUN, AND RADIOACTIVE PARTICULATE BASIS This specification is provided to implement the requirements of Sections II.C, III.A, and IV.A of Appendix I, 10 CFR Part 50. The Limiting conditions for Operation are the guides set forth in Section II.C of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive materials in gaseous effluent will be kept "as low as is reasonably achievabla" (ALARA). The calculational methods specified in the Surveillance Requirements implement the requirements in Section III.A of Appendix I that conformance with )

the guides of Appendix I be shown by calculational procedures based I on models and data, such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The methods for calculating the dose due to the actual release: rates of the subject materials are consistent with ,

the methodology provided in Regulatory Guide 1.109, " Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.111, " Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-cooled Reactors,"

Revision 1, July 1977. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions. The release rate specifications for Iodine-131, Tritium, and radioactive particulate with half-life less than eight days are dependent on the existing radionuclides pathways to man, in areas at and beyond the SITE BOUNDARY. The pathways which were examined in the development of these calculations were 1) l Individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leaf vegetation with subsequent consumption by man, 3 ) deposition onto grassy aruas where milk animals and meat producing animals graze with consumption of the milk and meat by OFF-SITE DOSE CALCULATION MANUAL Page 51

man, and 4) deposition on the ground with subsequent exposure of man.

l 3.10 TOTAL DOSE BASIS This specification is provided to meet the dose *. imitations of 40 CFR Part 190 that have now been incorporated Jr.to 10 CFR Part 20 by 46 FR 18525. The specification requires the preparation and submittal of a special Report whenever the calculated doses from plant radioactive effluents exceed twice the design objective doses of Appendix I. For sites containing up to 4 reactors, it is highly unlikely that the resultant dose to a MEMBER 07 THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if 1.he individual reactors remain within s.ae reporting requirement level. The special R? port will describe a course of action that.should result in the limitation of the annual dose to a MEMBER OF THE PUBLIC to within i the 40 CFR Part 190 limits. For the purposes of the Special Report, l it may be assumed that the dose commitment to the MEMBER OF THE {

PUBLIC from other uranium fuel cycle sources is negligible, with the ,

exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 8 km must be .

considered. If the dose to any MEMBER OF THE PUBLIC is estimated to j exceed the requirements of 40 CFR Part 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected), in accordance with the provisions of 40 CFR part 190.11 and 10 CFR Part j 20.405c, is considered to be a timely request and fulfills the .

requirements of 40 CFR Part 190 until NRC staff action is completed. .

The variance only relates to the limits of 40 CFR Part 190 and does l I

not apply in any way to the other requirements for dose limitation of 10 CFR Part 20, as addressed in Specifications 2.5-thru 2.9. An individual is not considered a MEMBER OF THE PUBLIC during any period in which he/she is engaged in carrying out any cperation that is part of the nuclear fuel cycle.

3.11 RADIOLOGICAL. ENVIRONMENTAL _MQHI.TORIN9_PRQ9 RAM _ BASIS l The radiological monitoring program required by this specification )

l provides measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides which lead to .

I the highest potential radiation exposures of MEMBER OF THE PUBLIC resulting from the station operation. This monitoring program .

thereby supplements the radiological effluent monitoring program by l verifying that the measurable concentrations of radioactive j materials and levels of radiation are not higher than expected on l l the basis of the effluent measurements and modeling of the l environmental exposure pathways. Program changes may be initiated based on operational experience.

The LLD's required by Table 2-9 are considered optimum for roucine environmental measurements in industrial laboratories. The LLD's for drinking water meet the requirements of 40 CFR 141.

3.12 RADIOLOGICAL ENVIRONMENTAL NONITORING PROGLAN LAND USE CENSUS BASIS This specification is provided to ensure that changes in the use of areas at or beyond the SITE BOUNDARY are identified and that modifications to the monitoring program are made if required by the results of this census. Adequate information gained from door-to-door or aerial surveys or through consultation with local agricultural authorities shall be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CPR Part 50.

Restricting the census to gardens of greater than 500 square fest ,

provides assurance that significant exposure pathways via leafy i vegetables will be identified and monitored since a garden of this j size is the minimum required to produce the quantity (26 kg/ year) of l leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumption were used: 1) that 20% of the garden was used for j growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and 2) a vegetatiori yield of 2 kg/ square meter.

l 3.13 RADIOLOGICAL ENVIRONMENTAL NONITORING INTERLABORATORY COMPARISON PROGRAN BASIS The requirement for participation in an Interlaboratory Comparison Program is provided to ensure that independent checks on the i precision and accuracy of the measurements of radioactive material in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are reasonably valid.

BASES 3.14 EIPLOSIVE GAS MIITURE This specification is provided to ensure that the concentration of potentially explosive ^ gas mixtures contained in'the Waste Gas Decay Tanks is maintained below the f1m==mhility limits of hydrogen and oxygen. Maintaining the concentration of hydrogen and oxygen below their flammability limits provides assurance that the releases of radioactive materials will be controlled in conformance with the requirements of General Design criterion 60 of Appendix A to 10 CFR Part 50.

3.15 WASTE GAS DECAY TANKS Restricting the quantity of radioactivity contained in each waste gas decay tank provides assurance that in the eve G of a simultaneous uncontrolled release of all the tanks' contents, the '

I resulting total body exposure to an individual at the nearest exclusion area boundary will not exceed 0.5 rom. This is consistent 12/67 l with Branch Technical Position ETSB 11-5.

3.16 WASTE GA8 DECAY TANK - EXPLOSIVE GAS MONITORING INSTRUMENTATION The OPERABILITY of the Wasta Gas Decay Tank explosive gas monitoring instrumentation or the sampling and analysis program required by this specification provides for the monitoring (and controlling) of potentially explosive gas mixtures in the Waste Gas Decay Tanks.

3.17 METEOROLOGICAL Ilf8TRUMENTATION The OPERABILITY of the meteorological instrumentation ensures the sufficient metootological data is available for estimating potential radiation doses to the public as a result of routine or accidental release of radioactive materials to the atmosphere. This capability is required to evaluate the needs for initiating protective measures to protect the health and safety of the public.

Setpoint Calculation 1.4-6 Turbine Building Basement Discharge Line Monitor (RM-L7)

(Continuous Type Releases)

INTRODUCTION The activity released through the Turbine Building Basement Discharge Line Monitor RM-L7 is analyzed in accordance with Section 1,2-5. The setpoint is a j fixed concentration based on worst case nuclide released at the worst case l

. rate as described in the Methodology Section below. The monitor setpoint is l adjusted to ensure isolation of the release pathway if nuclide concentration l limits are exceeded.

METHODOLOGY The alarm / trip setpoint determination is based on the worst case assumption that I-131 is the only nuclide being discharged. This assumption equates all counts on RM-L7 to I-131 with an ECL of 1E-6 uci/ml. I-131 has the most conservative ECL of the nuclides available to this release path and " visible" to RM-L7. The setpoint is based on assuring 10 ECLs or less of I-131 in the discharge canal and is determined by deriving the cpm from the RM-L7 calibration curve which corresponds to a concentration of 1E-5 vei/ml and applying the flow dilution factor, background counts, and statistical counting variations. The resulting value is used as the alarm / trip setpoint and RM-L7 is adjusted to this or a more conservative value to maintain control on

! release conditions.

Representative Sampling Method No. 3.1-1 (Evaporator Condensate Storage Tanks, Laundry & Shower Sump Tanks, Secondary Drain Tank)

To obtain representative samples from these tanks, the contents of the tank to be sampled will be recirculated through two contained volumes and a grab sample will be collected upon completion. No additions of liquid waste will be made to this tank until completion of the release.

Representative Sampling Method No. 3.1-2 (Secondary Drain Tank and/or Plant condensate)

A representative sample may be obtained via grab sample of the Turbine Building Sump or the Secondary Drain Tank, Plant Condensate, or from the release compositor.

Representative Sampling Method No. 3.1-3 (Weste Gas Decay Tank)

Representative gas, iodine, and particulate samples are drawn from the waste gas decay tank sample lines.

No additions of waste gas is allowed into a tank following sampling until the release has been completed.

Representative Sampling Method No. 3.1-4 (Reactor Building & Auxiliary Building & Fuel Bandling Area Exhaust)

Representative gas, lodine, particulate and tritium samples are taken from these duvue at the location of the radiation monitors. The sample for the E;.ccor Building Purge 'suct is taken form radiation monitor RM-A6 prior to a purge and is drawr *;om radiation monitor RM-Al during a purge. The sample for the Auxiliary Building and Fuel Handling Area Exhaust Duct is drawn from l RM-A2 during venting since this is a continuous release pathway.  !

If samples cannot be obtained from the ducts of the Reactor or Auxiliary Building, samples can be obtained from areas of these buildings that are considered to be representative of the radionuclides concentrations present throughout the respective buildings. Sampling times and volumes should be established to assure the LLD Limits of Sections 1.2 and 4.2 for the radionuclides can be met.

Representative Sampling Method No. 3.1-5  !

(Reactor Building With Personnel And Equipment Eatch opened) l l

l The following requirements do not apply when the Personnel Hatch or Equipment Hatch is closed, or when a structure, such as a wooden door, is used in lieu of either Hatch. By having one of these hatches closed, sustained drafts through the RB are prevented.

Requirements:

l The Reactor Building purge exhaust fans are operational and the supply fans

! are shut down. If the purge exhaust must be shut down then either the l

4/07 Personnel hatch or equipment hatch openings must be closed.

Monitor the Reactor Building recirculation system by using RM-A6 or by taking general area air samples.

considerations:

Run the main purge long enough to assure cleanup of the RB atmosphere.

! Degas and depressurize the Reactor Coolant System.

Representative Sampling Method No. 3.1-6 (Reactor Building During Integrated Leak Rate Test)

! Due to building overpressure, propurge samples cannot be taken from RM-A6.

Representative gas, iodine, particulate and tritium samples may be obtained from the Intermediate Building containment sampling apparatus or the Post-Accident Sampling System.

6.1 ORIGIN AND PURPOSE OF THE OFFSITE DOSE CALCULATIONAL NANUAL The Offsite Dose Calculational manual was developed to support the implementation of the Radiological Effluent Technical Specifications required by 10 CFR 50, Appendix I, and 10 CFR 50.36. The purpose of the manual is to provide the NRC with sufficient information relative to affluent monitor setpoint calculations, effluent related dose calculations, and environmental monitoring to demonstrate compliance with radiological effluent controls.

6.2 CHANGES 7/@7 The ODCM shall be changed in accordance with Technical Specifications (ref. ITS 5.6.2.3). In addition, interdepartmental reviews shall be performed as appropriate.

6.3 REVIEW The ODCM and its implementation shall be reviewed every 24 months (ref. FSAR 1.7.1.18) 6.4 UNPLANNED RELEASES .

An UNPLANNED RELEASE is an unintended discharge of liquid or airborne radioactivity to the environment.

Examples:

Releasing the wrong waste tank.

Plant leakage which exceeds reporting limits such as those of 50.72 and 50.73.

)

OFF-SITE DOSE CALCULATION MANUAL Page 147

I Clarification:

The Auxiliary Building ventilation system is designed to handle leakage from various plant components. Leakage of this sort is not considered unplanned unless the magnitude of the leak is ,

significant (i.e. reportable). Minor equipment failures which l' cause an increase'in plant releases are not unplanned as it is expected that minor failures will occur from time-to-time.

Human error which results in a release of radioactivity to the environment is considered unplanned.

6.5 RADIOACTIVE EFFLUENT RELEASE REPORT This report is submitted as required by Technical Specification 5.7.1.1.c to Crystal River Facility Operating License No. DPR-72.

The following information is included:

A summary of the quantities of radioactive liquid and gaseous ,

effluents and solid waste released from the plant as outlined in l Regulatory Guide 1.21 (Rev. 1, 1974) with data summarized on a quarterly basis following the format-of Appendix B thereof.

t An annual summary of hourly meteorological data collected over I the previous years. (In lieu of submittal, this data is maintained on-site and is available to the NRC upon request.)

For each type of solid waste shipped off-site Container Volume Total curie Quantity (specified as measured or estimated)

Principal Radionuclides (specified as measured or estimated)

Type of Waste (e.g., spent resin, compacted dry waste)

Type of Container Solidification Agent (e.g., cement)

A list and description of unplanned releases to unrestricted areas.

Process Control Program (PCP)

Off-Site Dose calculation Manual (ODCM)

Radioactive Waste Treatment Systems A list of new Environmental Radiological Monitoring Program dose calculation location changes identified by the land-use census.

Information relating to effluent monitors being inoperable for 30 or more days.

6.6 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT This report is submitted as required by Technical Specification 5.7.1.1.b to Crystal River Facility Operating License No. DPR-72.

The following information is included:

- Summaries

- Interpretations

- Unachievable LLDs, and An analysis of trends of the results of the radiological environmental studies and previous annual reports.

An assessment of any observed impact of plant operation on the environment.

NOTE: If harmful effects or evidence of irreversible damage are detected by the monitoring, the Report shall provide an analysis of the problem and a planned course of action to alleviate the problem. j

- Summarized and tabulated results, in the format of Regulatory Guide 4.8 (December 1975), of all radiological environmental samples taken during the report period.

NOTE: If some results are not available for inclusion, the j l report shall note and explain the reason for the 1 missing results. The missing results shall be i submitted as soon as possible in a supplementary report.

A summary description of the REMP.

- A map of all sampling locations keyed to a table giving distances and directions from the reactor.

- Unavailability of milk or fresh leafy vegetable samples required by Table 2-7 of Technical Specifications.

- The results of land-use censuses.

- Results of Interlaboratory Comparison Program.
