(j 16.3 _DJE[NLTJONS The definitions in the McGuire Technical Specifications apply to defined terms used herein. The following additional defined terms appear in capitalized type and are applicable throughout this Selected Licensee Commitment document:

16.3-1 AMSAC (ATWS Mitigation System Activation Circuitry) The Westinghouse system for mitigating ATWS events.

16.3-2 ATWS (Anticipated Transient Without Scram) An ATWS is an expec'ted l operational transient (such as loss of feedwater, loss of '

condenser vacuum, or loss of off site power) which is accompanied by a failure of the reactor trip system to shut down the reactor.

16.3-3 SOLIDIFICATION shall be the immobilization of wet radioactive wastes such as evaporator bottoms, spent resins, sludges, and reverse osmosis concentrates as a result of a process of thoroughly mixing the waste type with a SOLIDIFI-CATION agent (s) to form a free standing monolith with chemical and physical characteristics specified in the l Process Control Program (PCP). 1 l

t 16.11 RADIOLOGICAL EFFLUENT CONTROLS 16.11-1 LIQUID EFFLUENTS CONCENTRATION ~

COMMITMENT The concentration of radioactive material released in liquid effluents to UNRESTRICTED AREAS (see Figure 16.11-1) shall be limited to the concentrations specified in 10 CFR Part 20, Appendix 8. Table II, Column 2 for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2 x 10 ' microcurie /mi total activity.

APPLICABILITY: At all times.

REMEDIAL ACTION:

With the concentration of radioactive material released in liquid effluents to UNRESTRICTED AREAS exceeding the above limits, immediately restore the con-centration to within the above limits.

TESTING REQUIREMENTS:

Radioactive liquid wastes shall be sampled and analyzed according to the sampling and analysis program of Table 16.11-1.

The results of the radioactivity analyses shall be used in accordance with the methodology and parameters in the ODCM to assure that the concentrations at the point of release are maintained within the limits stateG above.

Publication 2 BASES:

This commitment is provided to ensure that the concentration of radioactive materials released in liquid waste effluents 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 in UNRESTRICTED AREAS will result in exposures within: (1) the Section II. A design objectives of Appendix I, 10 CFR Part 50, to a MEMBER OF THE PUBLIC, and (2) the limits of n 10 CFR Part 20. 106(e) to the population. The concentration limit for dis-(-) solved 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 16.11-1

\

i an equivalent concentration in water using the methods described in Interna-tional Commission on Radiological Protection (ICRP) pubitcation 2.

This commitment applies to the release of liquid effluents from all reactors at the site.

l The required detection capabilities for radioactive materials in liquid waste samples are tabulated in terms of the lower limits of detection (LLDs).

Detailed discussion of the LLD, and other detection limits can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L. A., " Limits for Qualitative Detection and Quantitative Determination - Application to Radiochemistry," Anal. Chem, 40, 586-93 (1968), and Hartwell, J. K., "Detec-tion Limits for Radioanalytical Counting Techniques," Atlantic Richfield Hanford Company Report ARH-5A-215 (June 1975).

TABLE 16.11-1 (Paae__2 of 3)

N]J TABLE NOTATION (1) The LLD is. defined, for purposes of t'iese commitments, as the smallest concentration of radioactive materi,1 in a sample that will yield a net count, above system background, that will be detected with 95% proba-bility with only 5% probability of falsely concluding that a blank observation represents a "real" signal.

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

4.66 s b LLD = E V 2.22 x 10' . Y exp (-lat)

Where:

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

s b is the standard deviation of the background counting rate or of tne 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 10' is the number of disintegrations per minute per micro-Curie, Y is the fractional radiochemical yield (when applicable),

i 1 is the radioactive decay constant for the particular radionuclide, and At is the elapsed time between midpoint of sample collection and time of counting (for plant ef fluents, not environmental samples).

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

It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement syste, and not, as an a posteriori (af ter the fact) limit for a particular measurement.

I TABLE 16.11-1 (Page 3 of 3)

TABLE NOTATION (2) 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.

(3) To be representative of the quantities and concentrations of radioactive materials in liquid effluents, samples shall be collected continuously or intermittently in proportion to the rate of flow of the effluent stream.

Prior to analyses, all samples taken for the composite shall be thor-oughly mixed in order for the composite sample to be representative of the effluent release.

(4) 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.

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

O (6) The principal gamma emitters for which the LLD specification applies V exclusively are the following radionuclides: Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-90, Cs-134, Cs-137, and Ce-141. The LLD for Ce-144 is 5x10

pCi/ml. This list does not mean that only these nuclides are to be detected and reported. Other peaks which are measurable and identi-fiable, together with the above nuclides, shall be identified and reported in the Semiannual Radioactive Effluent Release Report, i

BASES:

This commitment is provided to implement the requirements of Sections II.A.

III.A and IV.A of Appendix I, 10 CFR Part 50. The commitment implements the guides set forth in Section II.A of Appendix 1. The REMEDIAL ACTION state-ments provide the required operating flexibility and at the same time imple-ment the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable." Also, for fresh water sites with drinking water supplies that can be potentially 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 Part 141. The dose calcula-tion methodology and parameters in the 00CM implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix ! 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. Tha equations specified in the 00CM for calculating the doses due to the actual release rates of radioactive l materials in liquid effluents are consistent with the methodology provided ic Regulatory Guide 1.109, " Calculation of Annual Dose > to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 ,

CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.113, '

5. 10 CFR 50.36 BASES:

The inventory limits of the chemical treatment ponds (CTP) are based on limiting the consequences of an uncontrolled release of the pond inventory.

The expression in SLC 16.11-5 assumes the pond inventory is uniformly mixed, that the pond is located in an uncontrolled area as defined in 10 CFR Part 20, and that the concentration limit in Note 1 to Appendix 8 of 10 CFR Part 20 applies.

The batch limits of slurry to the chemical treatment ponds assure that radio-active material in the slurry transferred to the CTP are "as low as is rea-sonably achievable" in accordance with .0 CFR Part 50.36a. The expression in SLC 16.11-b assures no batch of slurry will be transferred to the CTP unless the sum of the ratios of the activity of the radionuclides to their respective concentration limitation is less than the ratio of the 10 CFR Part 50, Ap-pendix I,Section II,A, total body dose level to the 10 CFR Part 20.105(a),

either within or outside the SITE BOUNDARY, to annual average concentrations J 3xceeding the limits specified in Appendix B, Table II of 10 CFR Part 20 (10 CFR Part 20.106(b)). For MEMBERS OF THE PUBLIC will usually be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the SITE BOUNDARY.. Examples of calculations for such MEMBERS OF THE PUBLIC, with the appropriate occupancy factors, shall be given in the 00CM.

The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to a MENBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal-to 500 mrem / year to the whole 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.

This commitment applies to the release of gaseous effluents from all reactors at the site.

The required detection capabilities for radioactive materials in gaseous waste samples are tabulated in terms of the lower limits of detection (LL0s), De-tailed discussion of the LLO, and other detection limits can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L.

RADI0 ACTIVE EFFLUENTS 16.11-12 TOTAL DOSE COMMITMENT The annual (calendar year) dose or dose commitment to any MEMBER OF THE pVBLIC, due to releases of radioactivity and radiation, from uranium fuel cycle sources shall be limited to less than or equal to 25 mrem to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrem.

APPLICABILITY: At all times.

REMEDIAL ACTION:

With the calculated doses from the release of radioactive materials in liquid or gaseous effluents exceeding twice the limits of SLCs 16.11-3, 16.11-8 or 16.11-9, calculations should be made including direct radiation contributions from the units and from outside storage tanks to determine whether the above limits of this commitment have been exceeded. If such is the case, in lieu of O a Licensee Event Report, prepare and submit to the Commission within 30 days, a Special Report that defines the corrective action to be taken to reduce subsequent releases to prevent recurrence of exceeding the above limits and includes the schedule for achieving conformance with the above limits. This Special Report, as defined in 10 CFR Part P.O.405c, shall include an analysis that estimates the radiation exposure (dose) to a MEMBER OF THE PUBLIC from uranium fual cycle sources, including all effluent pathways and direct radia-tion, for the calendar year that includes the release (s) covered by this report. It shall also describe levels of radiation and concentrations of radioactive material involved, and the cause of the exposure levels or con-centrations. If the estimated dose (s) exceeds the above limits, and if the release condition resulting in violation of 40 CFR Part 190 has not already been corrected, the Special Report shall include a request for a variance in accordance with the provisions of 40 CFR Part 190, Submittal of the report is considered a timely request, and a variance is granted until NRC staff action l on the request is complete.

l TESTING REQUIREMENTS-Cumulative dose contributions from liquid and gaseous effluents shall be determined in accordance with SLCs 16.11-3, 16.11-8, and 16.11-9, and in l accordance with the methodology and parameters in the ODCH.

Cumulative dose contributions from direct radiation from the units and from radwaste storage tanks shall be determined in accordance with the methodology

( and parameters in the ODCM. This requirement is applicable only under condi-tions set forth the REMEDIAL ACTION of SLC 16.11-12.

This commitment is provided to meet the dose limitations of 40 CFR Part 190 that have been incorporated into 10 CFR Part 20 by 46 FR 18525. The speci-fication requires the preparation and submittal of a Special Report whenever the calculated doses from plant generated radioactive effluents and direct radiation exceed 25 mrem to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrem. For sites containing up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the individual reactors remain within twice the dose design objectives of 10 CFR Part 50, Appendix I, and if direct radiation doses from the units and outside storage tanks are kept small. The Special Report will describe a course of action that should resuit in the limitation of the annual dose to a MEMBER OF THE PUBLIC to within the 40 CFR Part 190 limits. For the purposes of the Special

\

Report, it may be assured that the dose commitment to the MEMBER of the PUBLIC from other uranium fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 8 km must be considered. If the dose to any MEMBER OF THE PubLIC is estimated to exceed the requirements of 40 CFR Part 190, the Special Report with a request for a varian;e (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 20.405c, is considered to be a timely request and fulfills the requirements of 40 CFR Part 190 until NRC staff ar. tion is completed. The variance only relates to the limits of 40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR Part 20, as addressed in St.Cs 16.11-1 and 16.11-6.

BASES:

This commitment is provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the Radio- '

logical Environmental Monitoring Program are made if required by the results of this census. The best information fron the door-to-door survey, from aerial survey, or from consulting with local gricultural authorities shall be used. This census satisfies the requirements of Section IV.B.3 of Appendix I-to 10 CFR Part 50. Restricting the census to gardens of greater than 50 m 8 provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/ year) of leafy vegetables assumed in O- Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were made: (1) 20% of the garden was used for growing bruad leaf vegetation (i.e., similar to lettuce and cabbage),

and (2) a vegetation yield of 2 kg/m . 8 4

16.11-16.1 ANNVAL RADIOLOGICAL ENVIRONMENT 3L OPERATING REPORT

Routine Annual Radiological Environmental Operating Reports covering the operation of the unit during the previous calendar veer shall be submitted prior to May 1 of each year. The initial report shall be submitted prior to May 1 of the year following initial criticality.

The Annual Radiological Environmental Operating Reports shall include summaries, interpretations, and an analysis of trends of the results of the radiological environmental surveillance activities for the report period, including a comparison with preoperational studies, with operational controls as appropriate, and with previous environmental surveillance reports, and an assessment of the observed impacts of the plant operation on the environment.

The reports shall also include the results of land use censuses required by SLC 16.11-14.

The Annual Radiological Environmental Operating Raports shall include the results of analysis of all radiological environmental samples and of all environmental radiation measurements taken during the period pursuant to the locations specified in the Table and Figures in the ODCM, as well as sum-marized and tabulated results of these analyses and measurements in the format of the table in the Radiological Assessment Branch Technical Position, Revi-sion 1, November 1979. In the event that some individual results are not available for inclusinn with the report, the report shall be submitted noting and explaining the reasons for the missing results. The missing data shall be submitted as soon as possible in a supplementary report.

The reports shall also include the following: a summary description of the Radiological Environmental Monitoring Program; at least two legible maps" covering all sampling locations keyed to a table giving distances and direc-tions from the centerline of one reactor; the results of licensee participa-tion in the Interlaboratory Comparison Program, required by SLC 16.11-15; discussion of all deviations from the sampling schedule of Table 16.11-7; and discussion of all analyses in which the LLO required by Table 16.11-8 page 2 of 2 was not achievable.

A single submittal may be made for a multiple unit station.

- 0ne map shall cover stations near the site boundary; a second shall include the more distant stations.

16.11-16.2 SEMIANNUAL RADI0 ACTIVE EFFLUENT RELEASE REPORT (See Note)

Routine Radioactive Effluent Release Reports covering the operation of the unit during the previous 6 months of operation shall be submitted within 60 days af ter January 1 and July 1 of each year. The period of the first report shall begin with the date of initial criticality.

The Radioactive Effluent Release Reports shall include a summary of the quantities of radioactive liquid and gaseous effluents and solid waste-

> tleased from the unit as outlined in Regulatory Guide 1.21, " Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radio-active Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants," Revision 1, June 1974, with data summarized on a quarterly basis following the format of Appendix B thereof.

The Radioactive Effluent Release Report to be submitted within 60 days after January 1 of each year e all include an annual summary of hourly meteorological data collected over th( srevious year. This annual summary may be either in the form of an hour-by-nour listing on magnetic tape of wind speed, wind direction, atmospheric stability, and precipitation (if measured), or in the form of hint frequency distributions of wind speed, wind direction, and atmospheric stability. [In lieu of submission with the first half year Radio-active Effluent Release Report, the licensee has the option of retaining this summary of required meteorological data on site in a file that shall be provided to the NRC upon request.) This same report shall include an assess-f ment o,' the radiation doses due to the radioactive liquid and gaseous '

i ef flus.nts released from the unit or station during the previous calendar year.

This same report shall also include an assessment of the radiation doses from radioactive liquid and gaseous effluents to MEMBERS OF THE PUBLIC due to their activities inside the SITE B0UNDARY during the report period. All assumptions used in making these assessments, i.e. , specific activity, exposurp time and location, shall be included in these reports. The meteorological conditions concurrent with the time of release of radioactive materials in gaseous effluents, as determined by sampling frequency and measurement, shall be used for determining the gaseous pathway doses. The assessment of radiation doses shall be performed in accordance with the methodology and parameters in the OFFSITE DOSE CALCULATION MANUAL (ODCM).

The Radioactive Effluent Release Report to be submitted 60 days after January 1 of each year shall also include an assessment of radiation doses to the likely most exposed MEMBER OF THE PUBLIC from reactor releases and other nearby uranium fuel cycle sources, including doses from primary effluent pathways and direct radiation, for the previous calendar year to show con-formance with 40 CFR Part 190, " Environmental Radiation Protection Standards for Nuclear Power Operation." Acceptable methods for calculating the dose contribution from liquid and gaseous effluents are given in Regulatory Guide 1.109, Rev. 1, October 1977.

The Radioactive Effluent Release Reports shall include the following information for each type of solid waste shipped offsits during the report period:

/O a. Total container volume, in cubic meters, 16.11-61~

e

b. Total Curie quantity (determined by measurement or estimate),

c. Principal radionuclides (determined by measurement or estimate),

d. Type of waste (e.g., dewatered spent resin, compacted dry waste, evaporator bottoms),

e. Number of shipments, and

f. Solidification agent or absorbent (e.g., cement, or other approved agents (media)).

The Radioactive Effluent Release Reports shall include a list and description of unplanned releases from the site to UNRESTRICTED AREAS of radioactive materials in gaseous and liquid effluents made during the reporting period.

The Radioactive Effluent Release Reports shall include any changes made during the reporting period to the PROCESS CONTROL PROGRAM (PCP) and to the OFFSITE 00SE CALCULATION MANUAL (00CM), as well as a listing of new locations for dose calculations and/or environmental monitoring identified by the land use census pursuant to SLC 16.11-14 Note: A single submittal may be made for a multiple unit station. The submittal should combine those sections that are common to all units at the station; however, for units with separate Radwaste Systems, the submittal shall specify the releases of radioactive material from each unit.
