RETS Manual Revision 4 Page 40 1.0 Gaseous Effluents 1.1 Alarm/Trio Set pints Specification 3.8.B.L requires that the dose rate at or beyond the site boundary (Figure 1.1) due to gaseous effluents from the site shaJ.L be limited at all times to the following values:
- l. 500 mrem/y to the total body and 3,000 mrem/y to the skin from noble gases.
- 2. 1,500 mrem/y to any organ from radioiodines and particul.ates.
Specification 3.2.K.L requires gaseous eff uent monitors to have alarm/trip setpoints to ensure that the above dose rates are not exceeded. This section of the ODCM describes the methodology that will be used to determine these setpoints. Figures 1.2 and 1.3 show the Offgas System, the Standby Gas Treatment System and normaL building ventilation with effluent monitor locations.
The methodology Eor determining alarm/trip setpoints is divided into two major pa ts. The fi st consists of backcalculat'ng from a dose rate to a re'ease rate limit, in pCi/s, for each nuclide and release point.
The secorid consists of using the release rate limits to determine the physical settings on the monitors. The methodology for the latter is contained in

Release Rate Limit Methodolo .Dose Rates First, a dose rate is calculated based on the design objective source te m mix used in the li'censing of the plant. Dose rates are determined for (1) noble gases and (2) iodines and particulates.
Release Rate Limit Methodolo Dose Rates Noble Gas Dose rates are caLculated for total body and sk'n, due to submersion within a cloud oE noble gases, using a semi-infinite cloud model. The use of a finite cloud modeL would result in calculated doses of 0 to 10 pere nt higher than those calculations using the semi-infinite cloud model Eor BPH. The dose rates are evaluated at the offsite locations with the highest expected concentrations, i.e., the nearest land site boundary points in each sector (from Table 1.1) and at other locations expected to be the maximum exposure points.
The nobl.e gas radionuclide mix used in this calculation is based on the design objective source term given in Table 1.2. Dispersion oE the released radioactivity is handled as described in Section 1.7 using historical. annual average meteorological data given in Table 1.3.
No credit is taken for shielding by residence.

RETS manual Revision 4 Page 42 Release Rate Limit i4fethodolo Eodine and Particulate Dose Rates For setpoints, the iodine and particulate dose rates are. calculated for the design objective source tezm given in Table 1.2. Dose rates are calculated for the critical organ, thyroid, of the critical age group, infant. Pathways considered are inhalation, ground contamination and milk ingestion. The dose rates are evaluated at the offsite locations with the highest expected concentrations, i.e., the nearest land site boundary points in each of the'16 sectors (from Table 1.1) and at other locations expected to be the maximum exposure points. This calculation assumes that a (hypothetical) cow is at each of these locations. These cows are assumed, conservatively, to obtain 100 percent of their food from pasture grass.
The inhalation, ground contamination, and milk ingestion dose rates (in mrem/year) for the selected organ (thyroid) and age group (infant) are calculated using Equation 1.13 as described in section 1..5.3. For determining the total thyroid dose rate from iodines and particulates:
DTa = Der + DTaG + D~ (1..3) where:
= total thyroid dose rate, mrem/yr.
Mz ~ thyroid dose rate due to inhalation, mrem/yr.
'DTBG ~ total body dose rate due to ground contamina"don,'rem/yr:.
The"thyroid dose rate is assumed to be equal to the total

body dose rate for this pathway.

1.2 Nonthl Dose Calculations Dose calculations will be performed once per 31 days to determine compliance with specifications 3.8.B.3 and 3.8.B.5. These specifications require that the dose at or beyond the site boundary due to gaseous effluents from each reactor at the site shall be limited to the following:
For noble gases,
- 1. During any calendar quarter, 5 mrad to air for gamma radiation and 10 mrad to air for beta radiation.
- 2. During any calendar year, 10 mrad to ai'r for gamma radiation and 20 mrad to air for beta radiation.

This section of the ODCM describes the methodology that will be used to perform these monthly calculations.

Doses are.to be calculated for the infant thyroid from milk ingestion and for the child bone and teen gastrointestinal tract (GIT) from vegetable ingestion. Releases of H-3, I-131, and I-133 are considered for the milk path~ay. H-3, Sr-89, Sr-90, Cs-134, and Cs-137 releases are considered for the vegetable pathway to the child bone. H-3, Co-58, and Co-60 releases are considered for the vegetable pathway to the teen GIT. The most critical real cow location is considered for the milk pathway and the most critical location w"'th a home-use garden is considered for the vegetable pathways (see Table 1.1). The cow is assumed to graze on pasture grass for the whole year.
The highest annual-average X/Q and D/Q based on 1977-1979 meteorological data (Table 1.3) will be used for ingestion pathway locations. Dispersion values are calculated .as described by Equations 1.15 and 1.16. Stack releases are consi.dered elevated releases. All other vent releases will be treated as ground level.

In the realistic model, all measured rad'onuclides are used to calculate garrma and beta ai" doses. ~ The dose is evaluated at the nearest land site boundary point in each sector and at other locations expected to be maximum. exposure points using a semi-infinite cloud model. The use of a finite cloud model would result in calculated doses of 0 to 10 percent higher than those calculations using the semi-infinite cloud model for BFN.
Historical onsite meteorological data from the period 1977-1979 (Table 1.3) will be used to calculate dispersion factors as described in section 1.7. Stack releases will be considered elevated releases.
Radwaste and reactor building releases will be considered split-level releases. Turbine building releases will be treated as ground level.
Radioactive decay is considered in this calculation.
The monthly release is averaged over one year to obtain an average release rate.

Dose Calculations A complete dose analysis utilizing the total estimated gaseous releases for each calendar quarter vill be performed and reported. as required in Specifications 6.7.5. Methodology for this analysis is that which is described in Section 1.5, using the quarterly release values reported by the plant personnel. All real pathways and receptor locations (as identified in Table 1.1) are considered. In addition, actual meteorological data representative of each corresponding calendar quarter w.'ll be used to calculate disoersion factors as descri'bed in section 1.7.
