3.0 GASEOUS EFFLUENTS r

3.1 Setpoint Determinations 3.1.1 Basis Stack gas and off gas monitor setpoints will be established such that the instantaneous release rate of radioactive materials in gaseous effluents does not exceed the 10 CFR 20 limits for ant.ual release rate. The setpoints rill be activated if the instantaneous dose rate at or beyond the i

(land) site boundary would exceed 500 aren/yr to the whole body

. or 3000 arem/yr to the skin from the continuous release of radicactive noble' gas in the gaseous effluent.

Monitor setpoints will be determined once per quarter under normal release rate conditions and will be based on the isotopic composition of the release and/or a more conservative default compositiot specified in the pertinent procedure. If l the calculated setpoint is higher than the existing setpoint, 1

it is not mandatory that the setpoint be' changed'.

Under abnormal site release rate conditions, monitor setpoints will be recalculated and, if necessary, reset at more frequent intervals as deemed necessary by C&RP Supervision. In particular, the JAF contribution shall be assessed.

During outages and until steady state power operation is again realized, the last operating setpoint shall be used.

l The skin dose rate limit is not used in setpoint calculations because it is never limiting.

(3) Based on the above conservatism, the dose contribution from JAF can usually be ignored. During Emergency Classifi-cations at JAF due 'to airborne effluent, the 500 ar/yr value must be reduced accordingly. 1 (4) To convert monitor gross count rates to pCi/sec release rates, the following general formula shr.11 be applied:

3.2 Dose and Dose Rate Determinations i

In accordance with specification 4.6.15.b.(2) and 4.6.15.b.(3), dose and dose rate determinations will be made monthly in order to determines (1) Total body dose rates and gamma air doses at the =mv4== X/Q 1and sector site boundary interface and beyond.

(2) Skin dose rates and beta air doses at the mari== X/Q 1and sector site boundary interface and beyond.

(3) The critical organ dose and dose rate at the maximum X/Q 1and sector site boundary interface and at a critical receptor location beyond the site boundary.

1 Either maximum five year annual average or real time meteorological data shall be utilized for dose and dose rate calculations. Where

~

==v4== five year average annual meteorological data is assumed, dose ,

, and dose rates due to noble gases at locations beyond the site boundary will be lower than equivalent site boundary dose and dose rates. Therefore, under these conditions, calculation of noble gas -

dose and dose rates beyond the maximum X/Q 1and sector site boundary L

locations can be neglected. '

The frequency of dose rate calculations will be upgraded when elevated release rate conditions specified in subsequent sections I

l 3.2.1.1 ana 3.2.1.2 are realized.

l Critical organ doses and dose rates may be conservatively calculated by assuming the existence of a so-called " moving" critical receptor.

At this " moving" critical receptor' location, it is assumed that all pathways are applicable and the highest X/A and/or D/Q value for actual pathways as noted in Table 3-1 are in effect. A person's dose at the " moving" critical receptor location is equal to the same dose that person would receive if they were simultaneously subjected to the highest pathway dose at each critical receptor identified for each pathway.

l If dose or dose rates calculated, using the assumptions noted above, i reach Technical Specification limits, actual pathways will be evaluated, and doses / dose rates shall be calculated at separate i

critical receptor locations and compared with applicable lini:s.  !

4 Not all pathways need be considered in dose and dose rate calculations at each critical receptor location. For example, when calculating land sector site boundary doses and dose rates for particulates, iodines and tritium, only the ground deposition and inhalation pathways apply.

. 3.2.2.1 Noble Gas Air Dose i The air dose at the critical receptor due to noble gas releases is determined as follows:

For gamma radiation

-8 D = 3.17 x 10 gg i7jg g i For beta radiation D ( 3.17 x 10-8IN gI/Q Qg where Mg = air gamma dose factor in (ar/ year per uCi/m ) for each isotope 1 (Table 4-1) '

Ng =

air beta dose factor (nrad/ year per uCi/m3 ) for each isotope 1 (Table 4-1)

X/Q = the relative plume concentration (in units of sec/m ) at the land sector site boundary or beyond. Either maximum 5 year ,

average annual values (Table 3-1 or Appendix C), or real time values may be assumed. 1 Qg = the total quantity of isotope i released during the period, (uci)

-8 3.17 X 10 = the inverse of the number of seconds in a year

3.2.2.2 Radioiodine, Tritium & Particulates The doses to an individual from I-131, I-133, tritium, and particulates with half lives greater than 8 days will be calculated as follows:

L Dose = 3.17 X 10-8 I I R 9 g ijak j1 Where W3 = dispersion parameter either X/Q (sec/a ) or 2

D/Q (1/m ) depending on pathway and receptor i location assumed. Either 5 year average annual values (Table 3-1, or Appendir c) or real time values may be assumed.

g= the total quantity of isotope i released during the period, (uci)

Rijak = the dose factor for each isotope i, pathway j, age group a, and organ k (Table 4-2, 1

through 4-20) 3.i7 x 10' = the inverse of the number of seconds in a year The R values contained in Tables 4-2 through 4-20 were 1 calculated using the methodology defined in NUREG-0133 and Regulatory Guide 1.109, Revision 1.

3.3 Critical Receptors For the meat consumption dose pathway, the critical receptor is the greatest D/Q meat animal location. This location has been determined in conjunction with the land use census (technical specification 3.6.22) and is subject to change. The vegetation (food crop) dose is based on the greatest D/Q garden location from which samples are taken. This location also may be modified as a result of vegetation i sampling surveys. ,

4.0 40 CFR 190 REQUIREMENTS The " Uranium Fuel Cycle" is defined in 40 CFR Part 190.02 (b) as follows:

" Uranium fuel cycle means the operations of milling of uranium ore, chemical conversion of uranium, isotopic enrichment of uranium, fabrication of uranium fuel, generation of electricity by a light-water-cooled nuclear power plant using uranium fuel, and reprocessing of spent uranium fuel, to the extent that these directly support the production of electrical power for public use utilizing nuclear energy, but excludes mining operations, operations at waste disposal sites; transportation of any radioactive material in support of these operations, and the reuse of recovered non-uranium special nuclear and by product materials from the cycle."

Section 3.6.15.d of the Technical Specifications requires than when the calculated doses associated with the effluent relerses exceed twice the limits of sections 3.6.15.a.(2)(b), 3.6.15.b.(2)(b) and 3.6.15.b.(3)(b),

then calculations shall be made including direct radiation contributions from the reactor units and outside storage tanks (as applicable) to determine whether the above 40 CFR 190 dose limits have been exceeded.

The doses from Nine Mile Pcint Unit 1 will be added to the doses to the maximum exposed individual that are contributed from other uranium fuel cycle operations within 5 miles of the site.

For the purpose of calculating doses, the results of the Radiological Environmental Monitoring Program may be included for providing more refined estimates of doses to a real maximum exposed individual.

Estimated doses, as calculated from station effluents, may be replaced by doses calculated from actual environmental sample results.

4.1 Evaluation of Doses From Liquid Effluents

.f For the evaluation of doses to real members of the public from liquid effluents, the fish consumption and shoreline sediment ground dose will be considered. The dose associated with fish consumption may be calculated using the ODCH methodology or by calculating a dose to man .

based on actual fish sample analysis data. The dose associated with shoreline sediment is based on the assumption that the shoreline would be utilized as a recreational area. This dose may be derived from liquid effluent data or from actual shoreline sediment sample analysis data.

Doses to members of the public from the fish consumption and shoreline sediment pathways will be calculaten using Regulatory Guide 1.109 methodology or ODCM methodology. ~

4.4 Doses to Members of the Public Within the Site Boundary.

Section 6.9.1.e of the Nine Mile Point Unit 1 Technical Specifications requires that the Sea;iannual Effluent Release Report 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 boundary as defined by Figure 5.1-1 of the specifications. A member of the public, as defined by the Technical Specifications, would be represented by an individual who visits the sites' Energy Information Center for the purpose of observing the educational displays or for picnicing and associated activities. It is assumed that an individual would spend four hours per week for twelve weeks at the Energy Information Center. The time spent at the facility is assumed to occur from approximately July 1 to September 30 of each year. Thus, the first Semiannual Effluent. Release Report

will not. address this particular dose because the summer season is the period of concern. The second reoort will~ address this dose based on forty eight hours occupancy.
  • The pathways considered for the evaluation include the inhalation pathway with the resultant lung dose and the direct radiation dose pathway with the associated total body dose. The direct radiation dose pathway, in actuality, include several pathways. These include: the direct radiation gamma dose to an individual from on overhead plume, a submersion gamma plume dose, and a ground plane dose (deposition). Other pathways, such as the in8estion pathway, are not applicable. In addition, pathways associated with water related recreational activities are not applicable here. These inicude swimming and vading which are prohibited at the facility.

radionuclides (radiciodine, tritium and particulates) in the effluent ,

for the appropriate time period. The radionuclide concentrations are then multiplied by the appropriate X/Q value, inhalation dose factor, air intake rate, and the fractional portion of the year in question.

Thus, the inhalation pathway is evaluated using the fol?owing

The direct radiation gamma dose pathway includes any gamma doses from an overhead plume, submersion in the plume and ground plane dose (deposition). This general pathway will be evaluated by everage 1

4 environmental TLD readings. At least two environmental TLD locations will be utilized and located in the approximate area of the Energy Information Center (EIC) and the facility picnic area. These TLDs will be placed in the field on approximately July 1 and removed on approximately September 30 of each year (this time interval is composed of one quarterly TLD collection period). The average TLD readings will be adjusted by the average control TLD readings. This l .is accomplished by subtracting the average quarterly control TLD

value from the average Elc TLD value. The applicable quarterly control TLD values will be utilized af ter adjusting for the appropriate time period (as applicable).

5.0 ENVIRONMENTAL MONITORING PROGRAM 5.1 Sampling Stations The current sampling locations are specified in Table 5-1 and Figures 5.1-1, 5.1-2. . The Environmental Monitoring Program is a joint effort between the Niagara Mohawk Power Corporation and the New York Power Authority, the owners and operators of the Nine Mile Point Unit 1 and the James A. FitzPatrick Nuclear Power Plant, respectively. Sampling locations are ei sen on the basis of historical average dispersion or deposition parameters from both units.

The average dispersion and deposition parameters for the two units have been calculated for a 5 year period, 1978 through 1982. These dispersion calculations are attached as Appendix C. The calculated dispersion or deposition parameters will be compared to the results of the annual land use census. If it is determined that a milk sampling location exists at a location that yields a significantly higher (e.g. 50%) calculated D/Q rate, the new milk sampling location will be added to the monitoring program within 30 days. If a new location is added, the old location that yields the lowest calculated D/Q may be dropped from the program after October 31 of that year.

5.2 Interlaboratory. Comparison Program Analyses shall be performed on samples containing known quantitiu of radioactive materials that are supplied as part of a Commission approved or sponsored Interlaboratory Comparison Program, such as the

, , , APPENDIX A DOSE PARAMETERS FOR IODINE - 131 AND - 133, PARTICULATES AND TRITIUM i This appendix contains the methodology which was used to calculate the dose 1 parameters for I-131, I-133, particulates, and tritium. The dose parameter, ,

Rg , was calculated using the methodology outlined in NUREG-0133 and Regulatory Guide 1.109, Revision 1. The radiciodine and particulate Technical Specification (Section 3.6.15) is applicable to the location in the unrestricted area where the combination of existing pathways and receptor age groups indicates the maximum potential exposure occurs, i.e. , the critical receptor. The inhalation and ground plane exposure pathways are considered to 4

cxist at all locations but the critical location will be used for dose purposes. The grass-goat-milk, the grass-cow-milk, grass-cow-meat, and vegetation pathways are considered to exist at specific locations. R g values have been calculated for the adult, teen, child and infant age groups for all pathways. The methodology used to calculate these values follows:

A.1 Inhalation Pathway j R = K(BR), (DFg),

where:

R = dose factor for each identified radionuclide i of the organ of interest (units = area /hr per uCi/m3);

K' = a constant of unit conversion:

6

= 10 pCi/uci; (BR), = Breathing rate of the receptor of age group a, (units = M /yr);

( DFg ), , = organ inhalation dose factor for radionuclide i for the receptor of age group a, (units = area /pCi). ,

1 ._ _ _ _ , ._

(

The breathing rates (BR), for the various age groups, as given in Table E-5 of Regulatory Guide 1.109 Revision 1, are tabulated below.

Age Group (a) Breathing Rate (m3/yr)-

Infant 1400 Child 3700 Teen 8000 Adult 8000 inhalation dose factors (DFA;), for the various age groups are given in Tables E-7 through E-10 of Regulatory Guide 1.109 Revision 1.
