ftQ PROCEDURii 6.1 General Consid_erations (Ll.1 Liquid Emuent Pathways Attachment I provides a simplified diagram of the liquid emuent produced by RSNGS. The liquid emuent discharge of RSNGS forms the headwaters of Clay Creek.
Dilution of the liquid emuent occurs off site at the confluence of Clay and Hadselville Creeks, and of Hadselville and Laguna Creeks, an.d at the confluence of Laguna Creek and the Cosumnes River.
Planned radioactive liquid releases are directed through the A or B RHUTs to give reasonable assurance of compliance with 10 CFR 50 Appendix 1 prior to their discharge to the retention basins (North or South). Prior to discharge from the retention basins to the plant emuent (off-site), the discharge rate from the retention basins and the amount of dilution from Folsom Sov'h Canal are controlled to ensure compliance with the concentration requirements in 10 CFR 20, 6.1.2 Gaseous Emuent Pathways Airborne radioactive material in the various rooms and systems at RSNGS is routed and discharged in airborne emuent as illustrated schematically in Attachment T The figure shows the functional arrangements of these streams, treatment and controls, radioactivity monitoring points, and emuent release points.

- 11 of 74 Potential release pathways other than those specified in Attachment 2 have been identified.
These release pathways are classified as NUISANCE pathways and include the following:
- 1) Auxiliary Boiler Vents / Reliefs -
- 2) hiiscellaneous Secondary System Steam Discharges j 3) Tank Atmospheric Vents l
3 Past experience has shown that the above release pathways do not contribute to the dose totals because of the small quantities released and the low concentration of radioactive i
materials. Therefore, Action Levels may be established for the secondary system q concentrations of radioactive material to trigger when the above routine gaseous emuent i releases shall be evaluated for off site dose impact The Action Levels shall be based on j levels that could contribute more than 5% to the most restrictive yearly dose limit. Action
' Levels shall be maintained through RSNGS piocedures.

. Unplanned releases shall be evaluated on a case by case basis.
- The Interim On site Storage (IOS) Building is a miscellaneous release.
l 6.1.3 hieteorological Data
, The atmospheric dispersion (X/Q) and deposition (D/Q) factors used in calculations involving airborne emuent are conservative default values. The default X/Q value is 1.0E-4
- sec/m', and the default D/Q value is 1,0E-6 m 2 These factors should be used to determine j monitor setpoints, assess compliance with the gaseous emuent requirements in Section 6.14, and calculate the gaseous emuent dose reported in the ARERR.
Attachment 4 contains dispersion and deposition factors calculated using actual meteorological data. These factors should not be used for dose calculations. They are
- presented for historicalinformation only. The factors are based on a 10-year annual average of meteorological data taken from January 1978 to December 1987. The raw data was I converted to X/Q and D/Q factors using the XOQ: OQ computer program.
614- Boundaries
' The Site Boundary for Gaseous Emuents as shown in Attachment 5 is for all calculations -
, involving gaseous emeents. The Site Boundary for Liquid Emuents as shown in Attachment 6 is for all calculations invohing liquid emuents. (Although the RHUTs are used as the dose
, accountabihty points for liquid emuents, the dose is considered to be received downstream of the boundary.)

consumption, actual occupancy rates, and dilution off site from additional converging streams (verses assumptions used for a HYPOTIIETICAL hiAXIMUM EXPOSED INDIVIDUAL based on Land Use Census data)J 61.6 Computers vs Manual Calculations Computer systems such as REIMS should be used for calculations in order to minimize error ;
and hasten the release process. However, in the event computers are not available for calculations, manual pre release calculations should be done based on the most historically restrictive receptor.
. 6.2 Liould Monitor Setooints The High alarm setpoint for the Retention Basin Emuent Discharge Monitor (R15017A)is based upon preventing the limits of the Specification in Step 6,14.2 from being exceeded. When the high alarm level is reached, any emuent discharges in progress are terminated or diverted to the Retention Basins.
A SAFETY FACTOR is included in the setpoint calculations to incorporate a margin of conservatism.
When a batch release is not occurring or the calculated setpoint is so low that it will cause spurious alarms, the monitor setpoint should be set close to background without causing spurious alarms or as determined by Radiation Protection / Chemistry Supenision.
The conversion factor and setpoint calculations should be performed based on the same radionuclide mix.
6.2.1 - Conversion Factors for F 1017A
- Provided here is the methodology to determine the conversion factor of counts per minute to microcuries per cubic centimeter for the Retention Basin Ellluent Discharge Monitor (R15017A). The conversion factor is based on the monitor's emeiency for each nuclide and the abundance of the nuclide. The mix ofisotopes used may be based on the historical mix provided in Attachment 7, current mix in the batch release, or as determined by Radiation Protection / Chemistry Supenision. The mix fraction shall be based on gamma emitting isotopes only.
The following equation shall be used to determine the conversion factor for R15017A:

6.3 Maximum Emuent Concentrations in Liquid Emuents The Maximum Efiluent Concentration Fraction is calculated to determine compliance with 10 CFR 20 requirements and the Specification in Step 6.14.2. Radioactive liquid emuent discharges normally originate in the RHUTs and are discharged into a retention basin. Samples are collected and analyzed from each retention basin prior to discharge to ensure that compliance with the Specification in Step 6.14.2 can be achieved.
In addition, calculations to determine the minimum dilution water flow rate and maximum retention basin discharge flow rate to ensure compliance are provided in this section. Any combination of minimum dilution flow rate and maximum discharge flow rate which satisfy the Specification is acceptable.
63.1 Maximum Emuent Concentration Fraction (MECF)
Lompliance with the Specification in Step 6.14.2 is anticipated when the MECF is less than or equal to 1,0. The MECF is calculated as follows:

! determine the setpoints for this monitor are contained in Reference 3.2.18.
The Gaseous Emuent Radiation Monitors have the capability to monitor gaseous emuents over three general ranges (high, middle and low) using four channels. In the permanently defueled mode, the middle and high ranges (Channels 2 and 3) are no longer necessary, and are no longer used or maintained, Channels 1 and 4 both operate in the low range and are the monitor 7
channels which are considered in this procedure.
f The Specification in Step 6.14.5 states that the gaseous emuent monitors shall have their alarm / trip setpoints set to ensure the limits of the Specification in Step 6.14.6 are not exceeded.
The conservative default atmospheric dispersion (X/Q) factor from Step 6.1.3 is used.
Compliance with the dose rate limits for noble gases specified in Step 6.14.6 is demonstrated by setting each gaseous emuent monitor alarm / trip setpoint so that an alarm / trip will occur at or
- before the dose rate limit is reached.
- A S AFETY FACTOR is included in the setpoint calculations to incorporate a margin of conservatism.
Maximum design flow rates for each release point will be used to calculate setpoints.

These flow rates should be used to determine monitor setpoints, assess compliance with the gaseous emuent requirements in Section 6.14, and calculate the gaseous emuent dose reported in the ARERR, Gaseous emuent release points and maximum design flow rates used at RSNGS are as follows:
Reactor Building Stack 74,000 CFhi Auxii.ary Building Stack 47,740 CFht 9-c+ - Auxiliary Building Grade Level Vent 31,000 CFM Interim On site Storage Building Ventilation

6.8 Dose Rate Calculations Compliance with the dose rate limits for noble cases in the Specification in Step 6.14 6 is demonstrated by setting each gaseous emuent monitor alarm setpoint so that an alarm will occur at or before either dose rate limit Specification in Step 6.14.6 is reached. In addition, the Specification in Step 6.14.6 provides a maximum limit on organ dose rate equivalent beyond the Site Boundary for Gaseous Emuents from tritium and all radioactive materials in particulate form with half-lives greater than 8 days. Compliance is determined by calculating the organ dose rate for the MAXIMUM EXPOSED INDIVIDUAL for the inhalation pathway only.

At all times.
ActioE With the calculated dose or dose commitment from the rele se of radioactive materials in liquid emuents exceeding any of the above Specifications, prepare and submit to the Commission within 30 days a Special Report. This Report will identify the cause(s) for exceeding the limit (s) and define the corrective actions to be taken to reduce the releases of radioactive material in liquid emuents and the propc ed corrective actions to be taken to assure that subsequent releases will be in compliance with the above Specifications.
Surveillance Requirements:
Cumulative dose assessments associated with the release of radioactive liquid efiluent shall be determined by sampling and analysis in accordance with Attachment 15, item B or item C, and calculations performed in accordance with the methodology described in Step 6.4 at the following frequencies:
- 1) Prior to the initiation of a release of radioactive liquid emuent from the A or B RIIUT; and,
- 2) Upon verification of monthly composite analysis results for radioactive liquid efiluent released from the A and B RHUTs.
A dose tracking system and administrative dose limits shall be established and maintained.
With the 31-day dose projection in excer.t of the limits in Step 6.14.4, adjust liquid efiluent operating parameters to give reasonable assurance of compliance with the dose limits of this Specification (10 CFR 50, Appendix 1 dose guidelines) and maintain radioactive liquid releases as low as is reasonably achievable.
Bases.
ODCM Step 6.14.3 is provided to implement the requirements of Sections ll.A, III. A, and IV.A of Appendix 1,10 CFR Part 50. This step implements the guides set forth in Section II. A of 10 CFR 50, Appendix 1. The Action statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of 10 CFR 50, Appendix I to assure that the releases of radioactive material in liquid efiluents will be kept "as low as is reasonably achievable " The dose calculation methodology in this manual implement the requirements in Section Ill. A of 10 CFR 50, Appendix 1 that confomiance
MANUAL: CHEMISTRY ADMINISTRATIVE NUMBER: CAP-0002 PROCEDURES MANUAL REVISION: 9 TITLE: OFF-SITE DOSE CALCULATION MANUAL PAGE: 30 of 74 with the guides of 10 CFR 50, Appendix I be shown by calculational procedures based on models and data, such that the actual exposure of an individual through appropriate pathways is unlikely to be substantially underestimated. The equations specified in this manual for
, calculating the doses due to the actual release rates of radioactive materials in liquid efiluents are consistent with the methodology provided in Regulatory Guide 1.109, " Calculation of Annual Doses to Man from Routine Releases of Reactor EfIluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix 1," Revision 1, October 1977 and Regulatory Guide 1.113, " Estimating Aquatic Dispersion of Efiluents from Accidental and Routine Reactor Releases for the Purpose ofimplementing Appendix 1," April 1977. There is reasonable assurance that the operation of the facility will not result in radionuclide concentrations in finished drinking water that are in excess of the requirements of 40 CFR 141.
The Lower Limits of Detection established in Attachment 15, item B are based on an estimated maximum annual efIluent outflow of 2 million gallons with a minimum annual average flow rate in the plant efiluent stream of 6,000 gallons per minute. The RHUT pre-release and monthly composite Lower Limits of Detection equate to an oft-site dose ofless than 10 percent of the 10 CFR 50, Appendix I guidelines. These Lower Limits of Detection, along with the dose tracking system, give reasonable assurance that the dose limits prescribed in ODCM Step 6.14.3 (the 10 CFR 50, Appendix I dose guidelines) will be met.
6 14.4 Liquid Etlluent Radwute Treatment Sprideations:
The LIQUID EFFLUENT RADWASTE TREATMENT SYSTEM shall be OPERABLE.
The appropriate portions of the system shall be used to reduce the quantity of radioactive materials in liquid ellluents prior to their discharge when projected doses due to the liquid elliuent beyond the Site Bouncary for Liquid Efiluents (see Attachment 6), when averaged over 31 days, would exceed 0.25 mrem to the total body or 0.83 mrem to any organ (8.33%
of the 10 CFR 50, Appendix 1 annual guidelines).

- 2) With less than the minimum number of radioactive gaseous efiluent monitoring instrumentation channels OPERABLE, take the Action shown in Attachment 16. Exert best efforts to return the instrument to OPERABLE status within 30 days and if unsuccessful, explain in the next Annual Radioactive Efiluent Release Report why the inoperability was not corrected in a timely manner.
Surveillanedsguirements:
The maximum setpoints shall be determined by procedures implementing the methodology presented in this procedure and shall be recorded on release permits.
Each gaseous efiluent monitoring instrumentation channel shall be demonstrated OPERABLE by performance of the INSTRUMENT CHANNEL CHECK, sol'RCE CHECK, INSTRUMENT CHANNEL CAllBRATION, AND CHANNEL TEST at th, frequencies shown in Attachment 17.
Records shall be maintained in accordance with the Process Standards of all radioactive gaseous emuent monitoring instrument alarm / trip setpoints Maximum setpoints and setpoint calculations shall be available for review to ensure that the limits of Step 6.14.6 are met.
Blfis The radioactive gaseous etlluent monitoring instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous efiluents during actual or potential releases of radioactive gaseous emuents. The alarm / trip setpoints for these instmments, except for the Interim On-site Storage (IOS) Building vent monitor (R15106),
shall be calculated in accordance with the methodology contained in this manual to ensure that the alarm / trip will occur prior to exceeding the limits of ODCM Step 6.14.6. The monitor setpoints for R15106 are set statistically high enough above background to pievent spurious alarms, yet stop potential radioactive releases when detected (Reference 3.2.18).
The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60,63, and 64 of Appendix A to 10 CFR Part 50.
The IOS Building has a ventilation system which provides protection against radioactive airborne releases. Operation of the ventilation system produces a negative pressure in the building. During operation, the ventilation exhaust flow is continuously monitored for particulate activity. Upon an alarm, the exhaust duct closes and the supp.; and exhaust fans stop, minimizing any chance of an airborne release. Although no planned airborne radioactive releases are anticipated from this pathway, the ventilation exhaust monitor is included in Attachment 16.
Fuel Storage Building exhaust is directed to the Auxiliary Building Stack where the exhaust is filtered and monitored for any activity prior to release to the atmosphere.

The Lower Limits of Detection (1,LDs) for the radionuclides presented in this table are the smallest concentrations (expre . ed in rnicrocuries per milliliter) which are required to be detected, if present, in order tr .:hieve compliance with the limits of Step 6.14.3 (10 CFR 50, Appendix !) for a RHUT transfer to a retention basin and assurance of compliance with the limits of Step 6.14.2 (10 CFR 20, Appendix B, Table 2, Column 2) for a Retention Basin Discharge.
- 2. The LLD of a radioanalysis system is that value which will indicate the presence or absence of radioactivity in a sample when the probability of a false positive and of a false negative determination is stated. The probabilities of the false positive and false negative are tsken as equal at 0.05. The general equation for estimating the mat 'um LLD in microcuries per milliliter is given by the following:
2.7 + 3.29 x S b LLD = 5 (3.70 E + 04)(Y x E x V)e(4'd Where:
2.71 = factor to account for Poisson statistics at very low background count rntns 3,29 =
two times the constant used to establish the one sided 0.95 confidt nee interval 3.70 E+04 = disintegrations /second/microcuric Y = yield of radiochemical process, i.e., the product of all factors such as emission fraction, chemical yield, etc.
E = counting efficiency (count / disintegrations)
V = sample volume (milliliters)
A = the radioactive decay constant for the partice!ar nuclide (seconds)

- 3. The LLD is defmed as an a priori (before the fact) estimate and is not to be calculated for each sample analyzed on an a posteriori (afler the fact) basis.
(b) A batch release is the discharge ofliquid wastes of discrete volume from the north or south Retention Basin. The Retention Basins are the maximum permissible concentration accountability points for 10 CFR 20, Appendix B compliance.
(c) A RHUT will be isciated and its contents thoroughly mixed to assure representative sampling prior to transfening the contents to a Retention Basin. The A and B RHUTs are the dose equivalent accountability points for 10 CFR 50, Appendix I compliance.
(d) Isotopic peaks which are measurable and identifiable from a RHUT sample analysis shall be reported and included in ODCM evaluations. Nuclides which are not observed in the analysis shall be reported as "less than" the nuclide's a posteriori mininium detectable concentration and shall not be reported as being present. The "less than" results shall be considered "zero" for the purposes of ODCM evaluations; hc, wever, if a nuclide is measured and identified at a value less than the Attachment 15 LLD value, it shall be reported and entered in ODCM evaluations.
(e) A composite sample shall be obtained by reing liquid aliquot volumes in proportion to the volume ofliquid released from each RHUT. Preparation of the composite is identical no matter which release scenario, or combination of scenarios, was used to release the RHUTs. If any RHUT which is part of the composite was released using the Rapid Release Scenario, the composite will be analyzed accordmg to the Rapid Release Scenario.

(f) Release of each Ri'UT may proceed along either of two separate scenarios depending on operational requirements. Normally, the Standard Release Scenario will be used for RilUT releases. The Rapid Release Scenario will be used when operational requirements dictate expediting the release process. In either scenario, the sr.mple must eventually be analyzed to an LLD level which equates to an off-site dose ofless tha; 10 percent of the 10 CFR 50, Appendix I guidelir.es. Preparation of the Monthly Composite is independent of the scenario used to release each RiiUT during a calendar month: the composite must be prepared for either scenario, only the analysis requirements differ. These Lower Limits of Detection for either or both scenario may change as the maximum annual eflluent outflow or the minimum annual average flow rate in the plani efiluent stream changes.
- 1. Slanditrd Release Scenario. This scenario uses the lower LLDs on a pre-release basis, resulting in correspondingly longer analysis intervals. In this scenario, the monthly composite does not need to be analyzed for gamma emitters. The pre-release and post-release (monthly composite)
LLDs equate to an off site dose ofless than 10 percent of the 10 CFR 50, Appendix I guidelines.
- 2. Rapid Release Scenario. This scenario allows the use of higher LLDs for pre-release dose calculations, resulting in correspondingly shorter analysis intervals. The pre-release LLDs equate to an off-site dose ofless than 20 percent of the 10 CFR 50, Appendix I guidelines. The post-release (monthly composite) LLDs equate to an otT site dose ofless than 10 percent of the 10 CFR 50, Appendix I guidelines 11-3 and Ce 144 analyses are specifically required only on a pre release basis. The LLDs for 11-3 and Ce-144 are required for the pre-release analysis only, however, these LLDs were included in the determination of post-release LLDs which meet the 10 percent criteria.

(b) Tritium grab samples shall be taken at least once per seven days from the ventilation exhaust from the auxiliary building stack anytime fuel is in the spent fuel pool and the pool temperature exceeds 110 F. Below 110*F there is ersentially no evaporation from this source.
(c) Principal gamma emitters for which the LLD applies are: Kr-85 for gaseous samples and Mn-54, Co-60,2n-65, Cs 134, Cs 137, and Ce 144 for particulate samples. This does not mean only these nuclides will be detected and reponed. Other peaks that are measurable and identifiable shall be reported in the Annual Radioactive Efiluent Release Report, pursuant to Step 6.15.1. All peaks which are measurable and identifiable shall be reported and entered into the ODCM evaluations.
Nuclides which are not observed for the analysis shall be reported as "less than" the nuclide's a posteriori minimum de'ectable concentration and shall not be reported as being present. The "less than" results shall be considered "zero" for the ODCM evaluations; however, if a nuclide is measured and identified at a value less than the Attachment 18 LLD value, it shall be reported and entered into ODCM evaluations.
(d) A gross beta analysis is performed on a monthly basis for each environmental release particulate sample.
