Rev. 0 APPENDIX C LIQUID DOSE CALCULATIONS - LADTAP A. PURP0SE This procedure may be used to calculate the quarterly (or any other time period) doses to both the maximum individual and the 50 mile population due to radionuclides released in liquid effluents from either Connecticut Yankee or Millstone Units 1 or 2. The procedure involves the use of the computer code LADTAP which was developed by the NRC in order to perform dose calculations in accordance with Regulatory Guide 1.109. B. REFERENCES 1. User's Manual for the LADTAP Program - 8 page printout. j 2. U.S. N.R.C. Regulatory Guide 1.109, 3. U.S. N.R.C. Regulatory Guide 1.113. 4.

PREREQUISITES The plant must supply the total number of Curies released for each radionuclide during the time period involved. D. PRECAUTIONS ek None. E. LIMITATIONS AND ACTIONS None. F. PROCEDURE 1. Review the plant curie tables for accuracy and completeness. If the strontium results are not yet available, but the calculations must be performed in order to meet the semiannual effluent report schedule, the code may be run without the strontium values and the doses due to strontium ratioed by hand by comparison with the previous quarter's results. 2. Obtain the computer deck for the proper site - there is one deck for Connecticut Yankee and one deck for Millstone. The Millstone deck may be used for both Units 1 and 2, however the quarterly doses must be calculated for each plant separately.

Section a - Justification for Method Used to Determine K & S' There are many different sources contributing to the releases from the ventilation stack. These include releases from the building ventilation, condenser air ejector, containment purges, flashed gases which occur while obtaining primary coolant samples, and i discharges from the waste gas tanks. These sources may exist in any possible combination and each has its own particular, but changing, nuclide mixture. Thus, the ratio of nuclides being released is a constantly changing parameter. It is impractical to change the value of K(S) and thus the release rate limit and monitor set-points each time a source stream is initiated or terminated or an isotopic analysis is performed on any of the_ source streams. Instead, we can choose a conservativ: value for K(S) such that whatever combination of source streams exists, the actual value of S or K will be less than that assumed. Table 2 indicates that the highest values of K (S ) occur for the _ g g shorter half-life noble gases. Therefore, the highest value of K(S) would be obtained with_a_ sample having the least amount of decay. Thus, if we determine K(S) using the gas mixture in the primary coolant we will be conservative because the mixture from any other source will be decayed from this value.

Section b - Determination of Release Rate Limit - Methods 2 & 3 Method 2 still uses the super organ technique in that the dose factors given in Table 3 are for the critical organ for that particular nuclide, yet they are all summed together as if they were all the same organ. Method 3, by use of the GASPAR code, eliminates some of this 3 conservatism by calculating the dose to each organ using the dose factor for that particular organ for each nuclide, then the critical organ can be determined. i i l L

Rev. 0, APPENDIX E GASEOUS DOSE CALCULATIONS - GASPAR A. PURPOSE This procedure is used to implement the NRC computer code GASPAR in order to calculate the maximum individual and population doses due to radionuclides released in gaseous effluents. The code implements the semi-infinite cloud model and the dose calculation models of Reg Guide 1.109 and is used to calculate the following: 1. A1,1 maximum individual and population doses from Connecticut Yankee. 2. All maximum individual and population doses from Millstone Unit 2. A 3. Population doses from Millstone Unit 1. 4. Maximum individual organ doses from Millstone Unit 1. The maximum individual whole body and skin doses due to elevated releases from Millstone 1 should be calculated using the finite cloud model as performed by the EPA code AIREM. A more detailed description of the GASPAR code can be found in reference 1. B. REFERENCES 1. GASPAR dose code manuals - dated 10/17/75 and 2/20/76. 2. U.S. NRC Regulatory Guide 1.109. 3. U.S. NRC Regulatory Guide 1.111. C. PREREQUISITES 1. The plant must supply the total number of Curies released for each radionuclide during the time period involved. 2. The meteorological programs must be run to generate the required input cards for X/Q, decayed X/Q, depleted X/Q and D/Q. D. PRECAUTIONS None. E. LIMITATIONS AND ACTIONS None.

Rev. 0 - F. PROCEDURE 1. Review the plant curie release tables for accuracy and completeness. If the strontium results are not yet available, but the calculations must be performed in order to meet the semi-annual effluent report schedule, the code may be run without the strontium values and the doses due to strontium ratioed by hand by comparison with the previous quarters results. 2. Obtain' the computer deck for the GASPAR code for the nuclear site involved. 3. The deck should be in the following order: // 082), 'CRANDALL', MSGLEVEL=1, CLASS =B // STEP 1 EXEC PGM=PFGASPAR // FT06F001 DD SYSOUT=A // FT05F001 DD

A maximum of 5 is all that can be done, A The meteorological program outputs the X/Q, decayed X/Q, depleted X/Q, and D/Q for the site ' oundary, nearest land, nearest residence and vegetable garden, goat farms and cow farms in each sector. The following locations should be entered: 1) The nearest land with highest decayed X/Q. 2) The nearest residence with highest depleted X/Q. 3) The goat farm with highest D/Q - 2nd & 3rd quarters only. 4) The cow farm with highest D/Q - 2nd & 3rd quarters only. J i

Rev. 0. The GASPAR program will calculate the whole body and organ doses for each pathway at each location. There is no way to control this with the input, but rather the final results will have to be selectively analyzed. For example, for the nearest residence location, one should only sum the dose due to the plume, ground deposition, inhalation and vegetation pathways and not from the cow's milk, goat's milk, and meat pathways. NOTE 1: For elevated releases from the Millstone 1 stack, the nearest land boundary and nearest residence may not be the location of highest X/Q's. Therefore the meteorological output table of X/Q's from 0-50 miles must be used and interpolated to determine these locations. NOTE 2: For CY and M2 which have more than one type of release-(batch, continuous, semi-elevated), d. the locations of highest X/Q's or D/Q's for one type of release may not be the same as the locations for a different type of release. In that case, the location of highest X/Q or D/Q for one type of release should also be entered for the other releases along with their highest locations, such that the total sum from all releases may determined at each location to determine the location of maximum dose. However, a maximum of 5 locations can be done. Thus, to prevent using the program more than once, some pre-judgement might be necessary. The format for the Special Location cards is as follows: Column 2= 1 - Eliminates pages of printout of nuclide r breakdown for each pathway and age group. 1 Columns 3 Location name - Example - Nearest Land. Coluains 19 Compass direction - Example - ENE Columas 23 Distance in miles - Example - 1.9. Columns 30 X/Q for that location - right justified - Example 0.273 E-07. Columns 40 Same as 30-39 except for decayed X/Q. Columns 50 Same as 30-39 except for depleted X/Q. Columns 60 Same as 30-39 except for D/Q. Columns 70, 71, 72, 73, 74, 75 and 76 - 0 in each column - controls printout. Last special location card is followed by 3 blank cards.

The table shows that the time period for batch releases is random when compared with time of day and thus the avg.

If another nuclide could add a significant 4 percent to the dose, some other organ will be critical. Iodine will not add to the other organs. If it could add a significant percent, the thyroid will be the critical organ. The use of these dose factors gives an annual dose assuming an average Ci/sec release rate. Since these dose calculations are for a period less than a year, a correction factor equal to the fraction of the year must be applied.
