lj MQ~'1.0 Gaseous Effluents 1.1 Alarm/Trio Set pints RETS Manual Revision 4 Page 40 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 Technical instruction 15.~~~~1.1.1'r',I~~Release~I~~f~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.

-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'DTBG~thyroid dose rate due to inhalation, mrem/yr.~total body dose rate due to ground contamina"don,'rem/yr:.
