l 1.0 DEMONSTRATION OF COMPLIANCE WITN 10CFR50, APPENDIX I, SECTION II lO I

\

{ This report summarizes the evaluation of the Montague Nuclear i Power Station e s capability to meet the requirements set forth in

{ Section II of Appendix I to 10CFR Part 50.

j The first part of this section provides the demonstration of conipliance with the requirements set forth in Section II.A, II.B, j and II.C. The second part addressesSection II.D of Appendix I.

l l 1.1 Compliance with Sections II.A, II.B. and II.C

! A cf.cparison of the Appendix I design objectives and' the calculated annual dose rates for individuals in the unrestricted area adjacent to Montague Units 1 and 2 is presented in Table 1.1 -$ . This comparison demonstrates that all design objective 9 set forth in Sections II.A., II.B., and II.C of Appendix 1 to 10CFR50 are satisfied.

l The calculated dose rates for individual pathways, from which the Table 1.1-1 summary has been prepared, are presented in Tables 1.1-2 through 1.1-27.

The doses associated with the release of noble gases are presented in Table 1.1-2.

The doses to the total body, skin, bone, liver, thyroid, kidney, lung, and gastro-intestinal tract of an individual, associated with radioiodine and particulate gaseous effluents, are presented in Tables 1.1-3 through 1.1-18. Thyroid doses are presented in Tables 1.1-19 through 1.1-22. Similar data are presented in Tables 1.1-23 through'1.1-27 for liquid radioactive effluents.

Separate data are presented in each case for the adult, teen, child, and intant age groups.

1.2 Compliance with Section II.D This section presents the results of cost-benefit analyses per-formed in accordance with Section II.D of Appendix I. Provided are esH mated costs for the most logical system augments which could be added to either the gaseous or liquid release streams.

1.2.1 Cost-Benefit Analyses

, The augments to the gaseous and liquid effluent systems and the 1 respective potential reduction to the annual population exposure l are shown in Table 1.2.1-1. The " benefit" of each augment ~is l calculated by multiplying the calculated dose reduction by 1,000 dollars per man-Rem (total body dose) or 1,000 dollars per man-thyroid-Rem (thyroid dose) , as shown in Table 1.2.1-2.

a = g .# -..

, he potential dose reductions to the annual population exposure based on the items of augmentation are shown in Table 1.2.1-1.

(O -

The calculated dose reductions were determined by assigning specific decon+ a=ination factors to each -augment, except Gaseous I Augments 6 and 7. Augments 6 and 7 result in an annual dose i reduction due to the fact that the release from the Mechanical i Vacuum Pump and the Off-Gas System, respectively, were assumed to be rerouted to the plant exhaust duct (i .e . , an elevated release) .

A decont==4 nation factor of 10 for iodine and 100 for particulates was used for each gaseous augment. mis is i consistent with Regulatory Guide 1.112, Revision 0 and j NUREG-0016.

A .decon+==4 nation factor of 10 for Anions, 10 for Cesium and Rubidium, and 10.for other nuclides was used for the liquid augment in order to provide consistency with NUR W O16.

The "on-line" time for both gaseous and liquid augments was conservatively assumed to be 100 percent for the purpose of this

/ analysis.

Table 1.2.1-2 shows the " benefit" of each augment, calculated by multiplying the annual dose reduction by $1,000 per man-Rem or

$1,000 per man-thyroid-Rem, as appropriate.

The total annualized costs shown on Table 1.2.1-2 for each of the potential augments were determined by using the methodology presented in Appendix A to Regulatory Guide 1.110, Revision O.

The total direct costs and total indirect costs for the specific equipment listed in Table 1.2.3-1 were determined from the data provided in Tables A-1, A-4, and A-5, of Regulatory Guide 1.110, Revision 0. Therefore, a labor cost correction factor of 1.6 and an indirect cost factor of 1.75 were utilized in these calculations.

^

Q The Northeast Utilities Service Company has established that the number describing the annual cost of money is 10.6 percent. This represents the annual cost of money for 1975. In order to determine the annual fixed costs for each augment, the total  ;

capital cost was multiplied by the Capital Recovery Factor of 0.1114. This factor was determined from the equation in Table A-6 of Regulatory Guide 1.110, Revision 0, using the 10.6 percent as the cost of money and an econcaic life of 30 yrs.

I The annual operating and maintenance costs for each augment, i I except the Gaseous Augments 7 and 8, were added to the total l 4 annual fixed costs. for each augment to determine the total i j annualized costs reported in Table 1.2.1-2. Annual operating and )

maintenance costs were determined from Tables A-2 and A-3 of

- Regulatory Guide 1.110, Revision O. No annual operating and maintenance costs were included for Gaseous Augments 6 or 7.

Table 3.1-1 presents the distances of each receptor relative to each release point.

j 3.1.1 Meteorological Data Onsite meteorological data for the one-year period, January 1, 1976 - December 31, 1976, were used as input to the calculational models shown in Section 3.2. Hourly-averaged values of wind speed and wind direction from the 150-ft level of the meteorological tower were used to approximate conditions for the

'j elevated portions of the conditionally elevated releases, while wind speed and wind direction parameters at the 70-ft level were ,

applied to ground releases and the ground portiens of the conditionally elevated releases. Hourly averaged values of' -

temperature difference between the 33-ft and 150-ft levels were used to estimate the atmospheric stability of the layer of air .

i through which the plume passes before reaching the ground.

l Atmospheric stability was derived from hourly-averaged values of .

1 temperature difference using the method presented in Regulatory f i

. Gaide 1.23 (Reference 2) .

- t l The data collected on the meteorological tower should be [

j representative of conditions in the vicinity of the Montague site [

because of the conformance of the data collection program to  !

accepted practices, the high data recovery rate, and the proximity of the tower to the proposed building complex. The i meteorological monitoring program was conducted in accordance b with Regulatory Guide 1.23 (Reference 2) specifications. -

difference observations was 93.6 percent. Data- recovery for j coincident 70-ft wind speed, 70-ft wind direction, and 33-150-ft  !

temperature difference was 94.8 percent. The meteorological -

l tower is located approximately 7,700 ft south of the Unit 1 reactor containment. This distance is sufficiently nearby to  :

provide meaningful data. The meteorological monitoring program has been discussed in more detail in the Montague CPS ER (Ref erence 3) , Section 6.1.3.1.

Table G-1 of Appendix G to the Environmental Report (Reference 4) presents the plant design parameter inputs which were used in the meteorological analyses.

3.2 Atmosoherie Transport and Dispersion Models Annual average and grazing season values of ' relative concentration (X/Q) , and relative deposition (D/Q) were ".

calculated using guidance presented in Regulatory Guide 1.111, Revision 1 (Reference 1) . In order to remain conservative, it was assumed that attendant plume depletion was always negligible (X/Q = (X/0)d ) . Hourly meteorological data, as discussed in Section 3.1.1, and the plant design parameters presented in i Table G-1 of the ER (Reference 4) were used as input to the models detailed in this section.

3.2.2 X/O value Methodology Annual average and grazing season values of relative concentration (X/Q) were calculated for contir. acus releases of activity from the plant exhaust duct, turbine building rooftop exhaust, and Unit 2 radwaste building rooftop exhaust (continuous releases) according to the straight-line' airflow (Gaussian) model presented in Regulatory Guide 1.111 Revision 1. The Unit 2 radwaste release was conservatively chosen since it had a smaller building wake, and thus higher X/Q. The bacic equation of this model is as follows:_ -

The entrainment coefficient (Eg) is a function of the ratio of ef flux velocity (U ) to elevated level wind speed (U i so ) for the conditionally elevated release pointe. For the ground level l

release point (Unit 2 radwaste building rooftop exhaust) , E g =1 (total entrainment) regardless of the wind speed condition. For the conditionally . elevated release points, the entrainment coefficient was defined as follows: .

E, = 0.0 when U,/U soi 2 5.0 Eg = 0.30-0.06 (Ue/Ut so ) when 1.5 < (U /Ui so ) < 5.0 Et = 2.58-1.St) (U./Ut so ) when 1.0 s (U /Ut sc ) s 1.5 (2) l Eg = 1.0 when Ug D150 < 1.0 Both the plant exhaust duct and turbine building rooftop exhaust releases were considered conditionally elevated The plant -

exhaust duct is between 1 and 2 times the height of the nearest ,

adjacent solid structure, while the turbine building rooftop exhaust is sufficiently distant from, and not too far below, the level of the nearest adjacent solid structure.

l Equation 1 was calculated at the nearest site boundary and nearest residence distances, and at the distance of the nearest vegetable garden larger than 500 ft2, the nearest milk cow, the nearest meat animal, and the nearest milk goat; all within 5 miles in each sector. Meteorological data for the entire

. annual period were used in the site boundary and nearest

residence calculations. For the vegetable and milk-pathway calculations, data from April 1 through September 30, were applied. This period corresponds to tue grazing season, and also approximates the vegetable growing season.

In the ground level portion of equation (1) , the building wake correction term was cenatrained to be less than or equal to 1.732 CT," .

3.2.3 _ (X/0)2 and D/O value Methodology hnnual average and grazing season depleted relative concentration values were conservatively assumed to be equal to annual average i and grazing season relative concentration values (X/Q = (X/Q)d ) a respectively. Therefore, no credit for attendant plume depletion of radioiodines and particulates was taken.

Annual average and grazing season relative deposition values were calculated using Regulatory Guide 1.111 Revision 1, Figure 7

(ground-level release) , Figure 8 (30 meter release) , Figure 9 (60 l l

For the elevated portions of the conditionally elevated releases, 5 Figures 8-10 were used to calculate the (6/Q)g (i=1-3) values; ,

while for the ground level release, and the ground level portion of the conditionally elevated release, Figure 7 was Used to calculate the (8/Q)q value.

3.2.4 Methodology Employed for the Intermittent Release The methodology employed in the calculation of X/Q and D/Q for an intermittent release is as follows, and . reflects current Site Analysis Branch practices plcference 6) :

1. One-hour sector-averaged X/Q values are calculated, using the model presented in Section 3.2.2, but without incorporating the terrain recirculation factors ( n (X) ) .

2. The 15 percent highest one-hour X/Q value was plotted at 1-hour on log-log coordinates of X/Q rs. time, while. the annual average or grazing season value was plottra at 8,760 hours0.0088 days <br />0.211 hours <br />0.00126 weeks <br />2.8918e-4 months <br />. A straight line was drawn, connecting the _.

two points.

3. Log-log interpolation, based on the total intermittent release period hours versus annual (8760) hours yielded both a X/Q and D/ Q multiplier.

4. This multiplier was then applied to the continuous -

release annual average and grazing season X/Q and D/Q '

values for the applicable release point, to obtain appropriate intermittent X/Q and D/Q values.

At the Montague Nuclear Power Plant, one intermittent release would occur as a result of mechanical vacuum pump operation during plant start-up for a total release of 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> per year.

j 4.1 Description i Connecticut River in the Vicinity of the Proposed Discharge 4.1.1 I

1 The proposed discharge is located on the Connecticut River at -

i  ; about river mile 117. This section of river between the Holyoke

, Dam (river mile 87) and the Turners Falls Dam (river mile 122) is referred to as the Holyoke Pool. The annual. average flow of the river in the vicinity of the site is approximately 13,500 cfs(1), '

with flows generally peaking during the months of March, April, j and May. See ER Section 2.5. for details of mavimum and =hi==.

.; flows and seasonal fluctuations.

The discharge is located in the riverine section of the Holyoke Pool. The depths and current speeds vary across and along the river so that there are both deep, fast flowing channels as well as quieter areas and gravel bars along this reach of the river.

The discharge structure extends from the east bank into the river .

(i for approximately 20 ft. The river bank in this area consists of ,

a steep rock ledge with a coarse gravel, cobble, and sand l substitute.  !

l Because of the steep banks on both sides of the river, the depth of the river and the current velocities vary widely with river flow. At annual average river flow in the vicinity of the proposed discharge, the velocity and depth of the river are 2.8 fps and 20 ft, respectively.  !

Me station discharges to the Cbunecticut River through a high velocity, submerged, single port diffuser. The. 15 in. diameter port will be angled 58 above the horizontal as requested by NRC '

(FES Section 5.3) . The annual average discharge flow is 13.2 cfs. The velocity ranges from 9 to 14 fps.  !

4.1.2 Other Surface Water Bodies

'nto bodies of water, Green Pond and Lake Pleasant, lie southeast  !

of the site. Green Pond lies approximately 0.9 mi southeast of ,

the site. Lake Pleasant is approximately 1.0 mi south-southeast I' of the site. Lake Pleasant and Green Pond are municipal water l

supplies for the Turners Falls Fire District.

i Lake Pleasant, with a surface area of' 53 acres, has a  ;

400 million-gallon storage capacity and about 1.25 mgd safe "

yield. Green Pond has a surface area of 15.2 acres, a l l 50 million gallon storage capacity, and a 0.25 mgd safe yield. A l' transfer pumping station pumps from Green Pond into Lake Pleasant when demand requires additional supply. '

4.2 Analysis This section and the dose calculation are based on an analysis  !.-

which is consistent with Regulatory Guide 1.109, Revision 0. The -

dilution factors are conservatively determined in accordance with

, Regulatory Guide 1.113, Revision 1.

The near field dilution factor at the edge of an initial mixing zone is calculated to be about 25, based on annual average conditions. For conservatism, the dose analysis was based on a

, near field dilution factor of 20 for all individual pathways.

No attempt was made to evaluate travel time or radioactive decay.

Full mixing of the discharge with river flow results in a dilution factor greater than 1000. All population doses were based on a conservative far field dilution factor of 100. The following paragraphs present a summary of the factors considered in the particular pathway analysis.

Potable Use of Connecticut River The Connecticut River, from the Ver:nont-New Hampshire-Massachusetts border to the Holyoke Dam is classified by the Department of Environmental Quality Engineering as Class B, suitable for fishing, swimming, and public water supply af ter appropriate treatment. Although the river is not presently meeting Class B standards due to sewage discharges, it is reasonable to expect that the river will be suitable for such uses during the life of the station, and probably by the 3 j

mid-80's. There is presently little use of the river for recreation, and none for drinking. The Applicants have made the

! assumption that the river will be used for recreation and as a drinking supply for thi a analysias.

Individual The nearest potential downstream location for individual '

residential use is at least 100 yards from the discharge.

However, a conservative application 'of a near-field dilution factor was made.

Population It was conservatively assumed that all towns bordering the river as far south as the Holyoke Dam draw half their drink 4M water

_, from the river. This represents a 2010 population of about 115,000 people. The large bulk of this population is located in the lower portion of the Holyoke Pool. Therefore, using a DF =

100 in the river will be conservative. No increase in the DF for the water treatment systems has been used, although an assumed DF

= 2 within the water supply system was applied. Thus the total DF = 200 for potable water use.

j Potable Use of Lake Pleasant and Green Pond i

(. 1 The Turners Falls Fire District draws water from a well field ,

j about 2.5 mi south of the site and from two surface water bodies,

! Lake Pleasant and Green Pond, about 1 mi southeast of the site.-

I This system served an esH =ated 6,100 people in 1973. The .w ell field is generally operated at about cafe yield of 0.7 adg with I the remainder of demand taken from a pumping station at Lake Pleasant. Green Pond is used to supplement Lake Pleasant.

Individual  ;

It was conservatively assumed that all of an individual's  ;

drinking water was obtained directly from Green Pond, although the system does .not physically operate by withdrawing directly -

from Green Pond.

t Population i e It was assumed that the well field operates at safe yield and I

( that the remainder of the water supply is provided by the safe yield of Lake Pleasant supplemented by Green. Pond.

l Conservatively assuming that 8,000 people will be served by the system, and using a per capita water usage of 150 gpd, results in  ;

, a water supply com p ed of 58 percent from the wells, 21 percent i from Lake Pleasant, and 21 percent from Green Pond.  ;

(_ Fish Consumption Individual ,

A dilution factor associated with the near field mixing zone was used in accordance with Regulatory Guide 1.109, Revision O.

Population , ,

() There is no commercial fishery within 50 miles of the site, and none is projected. Present fishing is recreational. Only l limited data from the mid-1960's are available, indicating i 13,000 pounds of fish per year were caught i=t.. ca Turners Falls  !

Dam and the Connecticut line. It was conservatively assuned that [

future fish catches will increase to 10s pounds of fish caught  !

! per year within 50 miles. The far field dilution factor (DF) was '

utilized to determine equilibrium concentrations of radionuclides in the fish. .

Population here are gresently no major public beaches dr wnstream of the discharge. However, when the river reaches Class B standards, ft '

is reasonable to assume that beach areas will be developed. Due to river topographr, velocity characteristics of the river, and i the population detsity, it is reasonable to expect beaches mostly in the lowr Holyalte Pool. Therefore, the far-field dilution factor is used. Iu wa.a assunnd that 100,000 people would use the Holyoke Pool for such activ) ties.

Irrigation Use of water from the Connecticut River in Franklin and Hampshire Countries for irrigation has not been desirable because of the existing low f1cvs below the Turners Falls Dam. A number of farms in the area have titad into town water supplies obtaining better quality water for Ligh-priced crops, mtch as tomatoes and ~

potatoes. Many other farms growing crops, such as corn and tobacco, rely on irrigation ponds within their properties or irrigation water from the tributaries to the Connecticut River.

t The Cooperative Extension Servlae of Hampshire County reports that no irrigation waters we re taken directly from the Connecticut River in Franklin or Hampshire Counties during the 1973 growing season. Therefore no exposure pathways associated with .trrigation activities were evaluated in this analysis.

Boatinq ..

Were are two public docks at river mile 98, one in I1orthampton and one across the Connecticut River in Hadley. Two public docks are located in South Hadley, one at river mile 91 and one at river mile 89.

Individual Individual dose calculations were based on the near field dilution factors.

Population Calculations for the general public used the far field dilution factor. The river usage was assuced to be 5,000 boaters.
