1.7 Definitioin ACTION 1.7.1 ACTION shall be that part of a specification which prescribes measures required under designat, d conditions.

ANALOG CHANNEL OPERATIONAL TEST 1.7.2 An ANALOG CHANNEL OPERATIONAL TEST shall be the injection of a simulated signal into the channel as close to the sensor as practicable to verify OPERABILITY of alarm, interlock and/or trip functions. The ANALOG CHANNEL OPERATIONAL TEST shall include adjustments, as necessary, of the alarm, interlock and/or trip setpoints such that the setpoints are within the required range and accuracy.

CHANNEL CAL l3 RATION 1.7.3 A CHANNEL CAllBRATION shall be the adjustment, as necessary, of the channel such that it responds within the required range and accuracy to known values of input. The CHANNEL Call 8 RATION shall encompass the entire channel including the sensors and alarm, interlock and/or trip functions, and may be performed by any series of sequential, overlapping or total channel steps such that the entire channelis calibrated.

CHANNEL CHECK 1.7.4 A CHANNEL CHECKS shall be the qualitative assessment of channel behavior during operation by observation. This determination shall include, where possible, companson of the channel indication and/or status with other indications and/or status derived from independent instrument channels measuring the same parameter.

GASEOUS RADWASTE TREATMENT SYSTEM 1.7.5 A GASEOUS RADWASTE TREATMENT SYSTEM is any system designed and installed to reduce radioactive gaseous effluents by collecting primary coolant system off gases from the primary system and providing for delay or holdup for the purpose of reducing the total radioactivity prior to release to the environment.

n In' reality, all of these effluent pathways utilize the' circulating water as dilution to the effluent stream, with the circulating water discharge canal being the point of release into an unrestricted area. Steam Generator ,

Blowdown Effluent may be released to the Circulating Water either directly in the Condenser outflow (the normal flow path) or in the first hours following startup via the Industrial and Sanitary Waste System (15WS) for chemical reasons. The Turbine Building Sump and Condensate Demineralizer Backwash Effluents enter Circulating Water via the sumps and ponds of the industrial and Sanitary Waste System.

To ensure compliance with ODCM specification 1.1.2.1 (T5 3.11.1.1).

-normally no dilution is assumed for dittages to the !rdustrial and Sanitary-Waste System. The assumption of no dilution limits div.harges to < .5 MPC and therefore ODCM specification 1.1.2.1 would not be compromised in the event circulating water dilution is lost. To add operational flexibility for abnormal conditions (radionuclide cor, centration in Turbine Building sump

> .5 MPC), discharges from the Turbine Building sump and concentrations in the 15W5 may exceed the operational objective, .5 MPC, provided circul4 ting water dilution is sufficient to ensure compliance with ODCM specification 1.1.2.1 and liquid effluents are being discharged in compliance with ODCM Specification 1.1.4.1 (T5 3.11.1.3). Two separate setpoint calculations are given for Turbine Building sump discharges (RM-L8). Section 2.1.4.2.1 describes the setpoint calculation normally used, limiting discharges to .5 MPC Section 2.1.4.2.2 provides an alternate setpoint methodology which $

may be !ned during abnormal conditions. RM-L8 set points are considered in compliance with ODCM specification 1.1.1.1 (T5 3.3.3.8) provided the setpoints are adequate to prevent releases in excess of ODCM specification 1.1.2.1 (T5 3.11.1.1).

Two mutually exclusive setpoint calculation processes are outlined below for A. am generator blowdown. Section 2.1.4.1 is to be used whenever Staam Generator Blowdown is being releesed directly to the Circulating Water in th+ Condenser outflow, which is the normal mode.

Section 2.1.4.2 is to 'r e m whenever Steam Generator Blowdown is being released to the Inde <tre d Sanitary Waste System, or diverted to the Nuclear Blowdown Process.ag System, both of which are alternate modes.

Normally, water collected by the Nuclear Blowdown Processing

/- System has very low specific activity. This water may be processed to the Turbine Building sump.

NOTE: When Circulating Water is unavailable for effluent dilution, releases ,

containing activity above LLD should be discouraged via pathways ODCM, V. C. Summer, SCE&G: Revision 16 (September 1991) 2.0-16

1 which lead tv it. Steam Generator Blowdown should be diverted to the Nuclear Blowdown Processing System. Condensate Deminera-lizer Backwash may be diverted to the Turbine Building sump or not released. Turbine Building sump effluent should be diverted to the ,

Excess Liquid Waste Processing System. (These steps are to keep the calculated dose to individuals as low as reasonably achievable.)

Furthermore, sampling and analysis of the Industrial and Sanitary -

Waste System is to be initiated and the measured concentrations used in the dose calculations of Section 2.2.

2.1.4.1 Steam Generator Blowdown Effluent Direct to Circulatina Water (Normal Mode}

Equation (1) is again used to assure that effluents are in compliance with the aforementioned specification:

Wn The available dilution water flow (Fo,) is dependent upon the mode of operation of the Circulating Water System. Any change in this value will be accounted for in a recalculation of equation (1).

The Steam Generator Blowdown flow rate (f ) and the Steam Generator Blowdown monitor setpoints (cs , and c33) are set to meet the condition of equation (1).

RM L3, the first monitorin the Steam Generator Blowdown i discharge pathway, alarms and terminates release of the stream. The discharge is then automatically diverted to the Nuclear Blowdown Pracessing System. RM-L10, the last monitor in the Steam Generator Blowdown discharge pathway, alarms and terminates the release.

Thus, RM-L10 is redundant to RM L3 and the setpoint (cs ,) wm W determined in the same manner as RM-L3 (c3 ,).

The method by which the monitor setpoints are determined is as follows:

ODCM, V. C. Summer, SCE&G: Revision 16 (September 1991) 2.0 17

1) The isotopic concentrations for any release source to be or being released are obtained from the sum of the measured '

concentrations as determined in Table 1.1-4. Equation (2)is again ernployed for this calculation:

j', C, = 1 c, 4 c, + c, + c, + cf 4 a where:

,S C, = the sum of the measured concentrations as determined by the analysis of the waste san ple,in uCi/mi,

{C, = the sum of the concentrations C,of each measured ga'nma emitting nuclide observed by gamma-ray spectroscopy of the waste sample,in uCi/ml.

C, = the measured concentration C, of alpha emitting composite sample,in uCi/ml.

C, = the measured concentrations of Sr-89 and Sr-90 in liquid waste as determined by analysis of the most recent available quarterly composite sample, in uCi/ml.

C, = the measured concentration of H-3 in liquid waste determined by analysis of the monthly composite sample,in uCi/ml, C, = the measured concentration of Fe-SS in liquid waste as determined by analysis of the most recent available ,

quarterly composite sample, in uCi/ml.

Isotopic concentrations for the Steam Generator Blowdown System effluent, the Turbine Building Sump Effluent, and the Condensate Demineralizer Backwash effluent may be calculated using equation (2).-

2) Once isotopic concentrations for the Steam Generator Blowdown have been determined, these values are used to calculate a Dilution Factor, DF, which is the ratio of the total dilution flow rate to effluent stream flow rate -

C F,, = (0.9)jF l1- 1 (18) where:

F, = the flow rate of the Circulating Water System during the time of the release. F, should normally fall between 1.78 X 105 and 5.34 X 105 gpm when the plant is operating and should be 5000 gpm when the plant is shutdown and the Circulating Water Jockey pump is operating.

C ,, = the concentration of radionuclide i,in uCi/mi,in the Circulating Water System intake, (that is, in the Monticello Reservoir). ' inclusion of this term will correct for possible'long-term buildup of radioactivity due .to recirculation and for the presence of activity recently released to the Monticel'o Retervoir by plant activities. For' expected discharges of liquid wastes, the summa-tion will be much less than 1.0 and can be ignored (Reference G).

Note that the equation is valid'only for DF > 1; for DF W1, ,

If f d?" f ,,a releases may be made as planned.. Because Fe ,is

normally very large compared to the maximum discharge pump capacity of the Steam Generator Blowdown System,-

it is extremely unlikely that f, < f,,. However, if a situation should arise such that fo < f ,,o steps must be taken to assure that equation (1) is satisfied prior to making the release.

These steps may include diverting Steam Generator Blowdown to the Nuclear Blowdown Processing System or ,

decreasing the effluent flow rate.-

When new candidate flow rates are chosen, the calculations above should be repeated to verify that they combine to form an acceptable release. If they do, the establishment of flow rate monitor setpoints should proceed as follows in Step 4. If they do not provide an acceptable release, the choice of candidate flow rates must -

be repeated until an acceptable set is identified.

5) The Steam Generator Monitor setpoints may be specified based on the values of E Ci, F,and f which were specified to provide compliance with the limits'of 10CFR 20, Appendix
  • 8, Table 11, Column 2. The monitor response is primarily to gamma radiation, therefore, the actual setpoint is based on E Cg. The monitor setpoint in cpm which corresponds to the calculated value c is taken from the monitor calibration graph. _ (See NOTE, page 2.014.)

l latino Water (Alternate Mode)

Equation (23) is again used to assure that effluents are in l compliance v/ith the aforementioned specification before dilution in the receiving water:

c5C Because dilution is not considered in the setpoint calculation, it is not necessary to calculate maximum permissible discharge flow rates or anticipated available dilutic,n flow rate.

The functions of the two monitors whos, setpoints are to be established are described in Section 2.1.4.1 above. The method for the determination is as follows:

1) If a release is found to be permissible, flow rate monitors for the active effluent streams (Steam Generator Blow-down - f , Turbine Building sump - fdt, and Condensate Demineralizer - fed) may have their setpoints established at any operationally convenient value. Since 10CFR 20 is to be ODCM, V. C. Summer, SCE8G Revision 16 (September 1991) 2.0 26

CF = 1 i i

Cry = g + SF (29) g in which all terms are defined in subsection 1.1.3.1 and subscript S refers to the Steam Generator Blowdown Effluent.

If CF 51, calculate c and determine the actual monitor setpoint (cpm) from the calibration curve.

If CF > 1 no release may be made via this path. The release must either be delayed or diverted for additional processing.

Because of spurious alarms, these remedial steps may be required if the monitor setpoints are only near the actual concentrations being released.

Within the above limitation, setpoint concentrations may now be calculated for the two effluent monitors. Because they are primarily sensitive to gamma radiation, their.setpoints will be based on the concentrations of gamma emitting radionuclides as follows:

2.1.4.4 Turbine Buildina Sump (Abnormal Conditions)

Provided circulating water is available,1 to 3 circulating water pumps, effluent exceeding .5 MPC may be released from the Turbine Building sump to the industrial and sanitary waste system, using the setpoint in this section, provided the following conditions are met:

1) instantaneous release rate limits of ODCM Specification 1.1.2.1 are not exceeded in the circulating water discharge canal,
2) The average radionuclide concentration in the industrial and sanitary -

waste system (Pond 6B or 008) will not exceed .5 MPC when averaged over one year,

3) The radionuclide concentration of the Turbine Building sump effluent does not exceed 15 MPC (ensures radionuclide concentration in discharge canal does not exceed .5 MPC, assuming maximum discharge from Steam Generator Blowdown through RM L3 and RM-L10 and only one circulating water pump operational),
4) The limits of ODCM specification 1.1.4.1 w;ll not be exceeded with the proposed release, and
5) Average discharge flow does not exceed values used in setpoint determination.

in addition, the sourt of radioactivity should be identified and isolated. Radionuclide concentration in Turbine Building sump effluent should _be restored to <.5 MPC as soon as possible and normal setpoint reestablished. Radionuclide concentration in Pond 6B and 008 should be restored to < LLD using dilution as necessary. Turbine Building sump samples should be obtained and analyzed every eight hours while the alternate setpoint is ODCM, V. C. Summer, SCE&G: Revision 16 (September 1991) 2.0-28

l 2.2 Dose Calculation For Liquid Effluents The method of this section is to be used in all cases for calculating doses to individuals from routine liquid effluents. Four notes at the end of the section confirm the values which certain parameters are to be assigned in some special cases.

2.2.1 Liquid Effluent Dose Calculation Parameters Term Definition " f hC Use An = the site related ingestion dose commitment 2.2.2 factor to the total body or any organ t, for each identified principal gamma and beta emitter listed in Table 2.2 3 in mrem ml per hr-pCi.

B F, a Bioaccumulation Factor for nuclide i,in fish, 2.2.2 pCi/Kg per pCi/l, from Table 2.21.

C4 = the average concentration of radionuclide, 2.2.2 i,in undiluted liquid effluent during time period at, from any liquid released,in uCi/ml.

DF,, = a dose conversion factor for nuclide,i, for 2.2.2 adults in preselected organ, t,in mrem /pCi found in Table 2.2-2.

O' = the cumulative dose commitment to the 2.2.2 total body or any organ, t , from the liquid ef fluents for the total time period, Eatk in mrem (Ref.1).

D* = Dilution Factor from the near field area 2.2.2 within one-quarter mile of the release points to the potable water intake for adult water consumption; for V. C. Summer, D, = 1.

F, = the near field average dilution f actor for C, 2.2.2 during any liquid effluent release.

K = 1.14 x 105, units conversion factor = 2.2.2 (106 pCi/uCi)(103 ml/l) + 8760 hrlyr ODCM, V. C. Su mmer, SCE & G: Revision 16 (September 1991) 2.0 32 1

Liould Effluent Dose Calculation Parameters (continued)

Term Definition Section of fhTtial Use Atk = the length (in hours) of a time period over -2,2.2 which concentrations and flow rates are averaged for dose calculations.

U, = 21 kg/yr, fish consumption (adult) 2.2.2 (Reference 3).

U, = 730 kg/yr, water consumption (adult) 2.2.2 (Reference 3).

Z = applicable near. field dilution factor when 2.2.2 no additional dilution is to be considered; Z = 1. ,

2.2.2 Methodology The dose contribution from all radionuclides identified in liquid effluents released to unrestricted areas is . calculated using the following expression:

13 = 1 Au 1 o'a % F a (31)

, s.n A,, = K, ( (U,/D,) + U,BF,) DF, (32)

FL = (average undiluted liquid waste flow) (33)

(average flow from the discharge structure) (2) 1 NOTE 1: If radioactivity in the Monticello Reservoir (C,,) becomes > the LLD specified in ODCM, Table 1.1-4, tha' concentration must be included in the Dose determination. Fcr this part of the dose calculation, F, .-: 1 and at, = the entire time period for which the dose is being calculated.

NOTE 2: During periods when the Circulating Water Pumps are not in operation, the possibility of leakage of activity from the industrial Water System will be accounted for as follows.

System will be initiated, and the measured concentrations of-

= radionuclides will be used in the dose calculations with F, = 1-and A t, = the entire time period for which the dose is being

,. calculated.

NOTE 3: During periods when the Circulating Water Pumps are in operation, any releases to the Sanitary and Industrial Waste System as to be credited with dilution in Circulating Water for dose calculation purposes, even though such dilution was not claimed in the setpoint calculation.-When taken in union with the note above, this procedure results in some overestimation of dose to the population because discharges made-to the

-Sanitary and Industrial Waste System just before loss of '

Circulating Water will be counted twice in the dose calculation -

process.

NOTE 4: If radioactivity in the Service Water becomes > LLD as determined by the analysis required by ODCM, Table 1.1-4, that concentration must be included in the Dose determination. For this part of the dose calculation, F, = 1 and a t,-= the entire time since the last Service Water sample was taken, O DCM, V. C. Summer, SCE &G: Revision 16 (September 1991) 2.0-34

1 The AT values for 61m - 10m are considered as primary indicators for determination of stability class. The 40m - 10m AT values are used only when 61m - 10m values are not available. All AT values are listed in F and are based on values in USNRC Regulatory Guide 1.23.

2 The 10m win'd speed is considered the pri. nary indication for windspeed. The 61m wind speed indication should oniy be used if 10m is not available.

No wind is required for planned releasec.

3.2.4 For the purpose of initial assessments of the impact of unplanned gaseous releases, dose calculations for the critical receptor in each affected sector may be performed using section 3 2.3.1 and section 3.2.3.2 equations as follows:

(1) For eacn affected sector, X/O and D/O will be calculated for one mile and critical receptor tocations using actual meteorological conditions occurring during the unplanned release. Actua! X/O and D/O values will be compared to annual average dispersion coefficients (E6, X/O', and D/O'). The more limiting dispersion coefficients will be used along with methodology in sections 3.2.3.1 and 3.2.3.2 for the initial assessment.

(2) The location of the critical receptors and the pathways j which should be analyzed are shown in Table 3.2 7. (h.ir very rough calculations, the annual average dispersion ct,*fficients (XTQ and CI/Q) for each receptor are shown in Table 3.2 0.)

(3) The Ry for the appropriate exposure pathways and age groups will be selected from Tables 3.2 3 through 3.2 6.

NOTE: The controlling receptor in each sector was identified in the following way. Receptor locations and associated pathways were obtained from the August 1991 field survey. A child was assumed at each location, except that where a milk cow was listed, an inf ant j was assumed. X/Q' for each candidate receptor was obtained by l interpolation of values in Table 6.1 10 of Reference 5; D/Q' for each  !

candidate receptor was obtained by interpolation of values in Table 6.113 of Reference 5. Expected annual releases of each nuclide were takers from Table 5.2 2 cif Reference 5. The pathway dose factors given above in Tables 3.2 3 and 3.2 4 were then u:ed with the referenced values in the methodology of Section 5.3 of Reference 1 to compute total annual doses at each candidate receptor site for the pathways existing at that site. The controlling -

receptor for each sector was then chosen as the candidate receptor with the highest total annual dose of any candidate receptor in the given sector. All listed pathways are in addition to inhalation and ground plane exposure.
