ATTACHMENT 3 Bases for Lower Limit of Detection Values for Rancho Seco Liquid Effluents i

's BASES FOR LOWER LIMIT OF DETECTION VALUES FOR RANCHO SECO LIQUID EFFLUENTS 4
M INTRODUCTION i 6 In a previous transmittal .1 to USNRC Region V, a statist- l ical basis for lower limit of detection (LLD) of radio-J nuclide concentrations in Rancho Seco effluents was estab- I lished. As indicated in that document, as the background for the analysis.of interest is lowered, the ratio of the dose represented by the LLD to the Technical Specification value also lowers. (Fig. 1) In the limit, as the background approaches 0, the ratio approaches 0.5. l The Sacramento Municipal Utility District proposes in this document a program which utilizes LLD's for the the liquid effluents at values which result in this ratio of 221 This program features a comprehensive management control and oversight process and dose tracking system. This approach is considered appropriate dce to the unusual characteristics . of the Rancho Seco site in which the liquid outfall of the site is the headwater of Clay Creek. Also, during much of the year, this flow also is a large part of the flow of Hadselville and Laguna Creeks. l The objective of this program is to achieve and maintain compliance to 10 CFR Part 50, Appendix I in a manner specific to the unusual environmental setting of the Rancho Seco site. 1 1 _ _ _ _ _ _ _ _ ________ _ _ _ _ _ i

1 %. jLJ1 HISTORY The origina1LTechnica1' Specifications-for liquid efflue'nts were based on'two premises: (Fig. 2) (1) The concentrations in 10 CFR Part 20 applied; (2). Normal operation precluded radioactivity in the. secondary system, and thus'in the liquid effluents. , e However, steam generator 1 tube leaks developed. Radioact-l
'ivity began to. appear frequently in the liquid effluent in 1981.
In 1984, liquid effluent Technical Specifications were adopted which contained LLD values which corresponded directly to the values used for the " standard plant". These
~
values were used \ until it was determined that the calculated 1 doses associated with these values were somewhat in excess of the Technical Specification values. (Fig. 3) At that time, interim LLD's were adopted to bring the situation more _ in agreement with Appendix I. (Fig. 4) 4 Usage factors on the stream system also changed in 1985. Prior to 1985, the stream system was extensively used by area residents downstream from the site boundary fence.
. Individuals claimed to have large consumption of aquatic foods from this aren. After 1984, information from these )
individuals indicated that usage of the stream system upstream from Laguna creek has essentially stopped. In addition, the area shown in Figure 5 was posted as a "No 2
~
Trespassing, No Hunting, No Fishing" area. During the period 1981-84, a database was established for the quantities of radionuclides released in the liquid effluent. The data for gamma emitters are presented in Table 1. Note that Cs134 and Cs137 together comprise nearly half of the activity. These values are used as the histor-ical radionuclides mix for dose and LLD calculations.
\
a h a 3
J_d DOSE 6EQ CONCENTRATION CALCULATIONS 3.1 Dose Calculation for Historical Mix The projected dose calculation methodology used at Rancho l Seco is based on Regulatory Guide 1.109 as implemented by the LADTAP software. This methodology was used to determine the fraction of total dose associated with each. radionuclides in the historical mix for the total body and for the most limiting organ for the nuclide. It was found that virtually all dose to the thyroid ir due to iodines, so the contri-bution from iodines was separated from the rest. The results are presented in Table 2. This table clearly indicates that Cs134 and Cs137 cre by far the major contri-butors to dose at 97.8% of the total body dose and 97.6% of the limiting organ dose. (Except thyroid)
\
The FIRST PROPOSAL is that Cs134 and Csl37 will be 1 indicators for dose for all gamma-emitting radionuclides except iodines. Table 3 contains the resulting dose fractions. The usage factors established before 1985 will continue to be used to provide conservatism until the land use census currently underway has been completed and the data evaluated. 3.2 Concentration (LLD) Calculations In the methodology as implemented by LADTAP, dose is propor-tional to the total quantity of activity released, all other i factors being constant. Three of these factors are under operational control. (Fig. 6) The others are built in to the database for the Offsite Dose Calculation Manual. (ODCM) I
4
'o The three factors under operational control include: (Fig.
6) (1) Annual volume of liquid effluent released from Regenerant Hold-Up Tanks A & B (RHUT A & B) (2) Concentration of radioactive materials in the effluent (3) Flow rate at the site outfall. The flow rate at the site outfall is normally held constant at 5000 1 10% gpm.. The concentrations in question are the LLD's to be established. The annual volume through RHUT's A
& B is also considered to be constant at 20 million gallons.
With Cs134 and Cn137 as the dose indicators for all gamma emitters, except iodines, the concentration equivalent of dose at the Technical Specification values of 3 mrem total body and 10 mren organ is illustrated in Figure 7. A The SECOND PROPOSAL is to place the LLD equivalent of dose at 50% of the Technical Specification values. (Fig. 7) 3.3 Laboratory Significance The proposed LLD's are achievable with a modest upgrade in equipment in the facilities which are available. Counting
\
times of 4000-6000 seconds are expected. State-of-the-art equipment and specialized facilities are not required to support the plant with reasonable delays. I l l 5 i

'i,_Rl MANAGEMENT ANDLADMINISTRATIVE CONTROLS 4.1 Management Control-System The effluent control program has been in a continuous state of evaluation and. improvement since late 1985. One result has been to develop a comprehensive Effluent Oversight Control Program.
(EOCP) This program defines policy, responsibilities, and interfaces. The EOCP is derived from a foundation of Technical Specifications, Regulatory Guides, and Safety Analysis Report, Industry Standards, j and Standard District Instructions. (Fig. 8) It addresses all effluent. paths (gaseous, liquid, solid), below regulatory convern, and related programs such as meteorology. The policy document (Fig. 8) is the Effluent Oversight Control Management Process. It defines the functional areas which are subject to EOCP and the responsibilities of each organization
.which is linked to the Program. Indirect linkages, such as Training Department, are included. Ultimate responsibility for the Program at Rancho Seco is placed on the Chief Executive Officer, Nuclear. The Manager, Environmental Protection is responsible for the implementation of the Program.
The implementing document (Fig. 8) for the Management Process is the Effluent Control Manual. This manual addresses the following: . (1) EOCP goals and objectives (2) Measures of organizational performance, management involvement, and Station trends 6
(3) Functional and organizational interfaces (4) Definition of data and information management systems. As indicated, (Fig. 8) the Effluent Control Manual provides the interfaces among effluent control, offsite dose calculation, environmental monitoring, solid radwaste process control, engineering, and other related programs. The ALARA manual defines ALARA goals and objectives for all Rancho Seco functions, including EOCP. 4.2 Administrative and Operational Controls These ecntrols include three principal components: l (1) Definition of LLD's (2) Administrative limits for dose associated with effluent releases (3) Dose tracking. 4.2.1 The historical mix of radionuclides released in Rancho Seco liquid effluent provides the basis for establishing LLD's. The preceding discussion has shown that the presence or absence of dose associated with these releases can be very adequately indicated by a combination of Csl34, CS137, and I131. The concept of setting the LLD's at a concentration equivalent to 50% of the Technical Specification values has also been developed. The resulting LLD's for liquid effluent offsite dose tracking purposes are shown in Table 4. 4.2.2 The District recognizes that the specification of LLD's at relative high fraction of 0.5 of Technical Specif-7 l
ication requires consideration of a relatively large
" unknown dose". (Fig. 9) The THIRD PROPOSAL accounts for the " unknown" by establishing an offsite dose administrative limit which is the difference between the Technical Specification value and the LLD equiva-lent. Numerically, the administrative limits become:
.)
Total Body ~-- 1.5 mrem Any organ -- 5.0 mrem j For convenience, during the balance of this present- l ation all references will be to the total body number l of 1.5 mrem. l i If it becomes necessary to consider exceeding this administrative limit, a management and technical review will be peEformed to determine the available options. 1 Unless a monthly composite has an unexpectedly high ! result as described below, the dose tracking system 1 would provide early indication that exceeding the administrative limit is forecast. 4.2.3 The District has established and used a dose tracking system for liquid effluent releases. This system would' be modified to best suit the 50% LLD and the 1.5 mrem administrative limit. The existing sampling, monit-oring and reporting system will be used until the Radiological Effluent Information Management System (REIMS) becomes operational. All dose calculations are performed in accordance with ODCM methodology. Manage-8
ment approval is required prior to all releases. The information flow for dose tracking will be as follows: (Fig. 10) (1) Prerelease dose calculation (2) Postrelease dose calculation (3) Weekly review of release records and update of dose calculation (4) Monthly composite of all REUT A & B releases (5) Monthly inclusion of composite results in the dose calculation (6) Monthly update of the remaining operating margin (7) Quarterly review of all release data, recalcu-lation of dose and update of operating margin (8) Semiannual effluent report preparation. The doses when calculated are plotted on a cumulative chart and compared to a target vector. (Fig. 11) The relative position of t'eh cumulative dose line to the target is used as basis for decisions to perform opera-tions such as recycling and demineralizing. The update of the operating margin is performed to account for results obtained from the composite sample. The purpose has both positive and negative aspects. On the positive side, the remaining operating margin may be increased because the actual concentrations of radionuclides in the composite are less than the average of the LLD's and observable concentrations obtained in the release analyses. (Fig. 12) The negative is that the composite analyses may result in 9
unexpectedly.high average concentrations with an accom-panying reduction in the remaining operating margin. 73 4.3 . Radiological Effluent Information Management System A computer-based effluent information system is in the initial stages of installation. A schematic of this system is shown in Figure 13. As. indicated, Radiation Protection, Chemistry, Environmental Programs, and Health' Physics. Support will be 1, inked to a common database. One signif-icant advantage to this' system is that the personnel who perform prerelease dose calculations will be using the same model as those who perform the followup weekly and monthly calculations. Features such as data-in-erpected-range prompting'are to be included.. Personnel will be trained and the system will be carefully phased in and customized to
\
Rancho Seco over'a period of a few months. Initial-produc-Y ! tion operation is scheduled for August 1, 1987. I i

SUMMARY
I The basis for a surveillance Technical Specification for 10 l l CFR Part 50 Appendix I compliance has been presented. Table 5 summarizes this Technical Specification. This Technical Specification establishes a method for compliance which takes into account the unique limnology of the Rancho Seco I site and the limitations of a well-equipped process analyt-ical laboratory. It provides reasonable assurance that the design guides in Appendix I will not be substantially exceeded
<nven under nominally adverse conditions. As bacicap and confirmation of the effluent control program, the District operates a comprehensive environmental monitoring program in the liquid effluent pathway.

- 1. The systematic error has been determined to be negligible with respect to random error.
- 2. The factor "exp(-Atc)" to correct for decay time from

b = blank background (counts) tb = blank count time.(seconds) ts = sample count time (seconds) tg r=1+ t b 3.70E4 = disintegrations /second/ microcurie Y= yield of radiochemical processes, i.e., the product of all factors such as emission fraction, chemical yield, etc. E= counting efficiency (count / disintegration) V= sample volume in liters or cubic meters, or mass in kilograms 4 [1 - exp(-At g)]exp(-Aty T= y 1 = decay constant (seconds -1) tc = time from midpoint of collection period to start of counting (4) When spectroscopy is used to analyze the sample, the following LLD equation is used: LLD = 2.71 + 4.65(B)0.5 3.70E4(YEVT) Where B is the counts in the Region of Interest. l
BASIS FOR TECHNICAL SPECIFICATION LLD The equation for lower limit.of detection is taken from Currie l, with minor modifications, as follows:
- 1. The systematic error has been determined to be negligible with respect to random error.
.2. The factor "exp(-Atc)" to correct for decay time from collection to analysis is'added for completeness.
- 3. The correction factor (2.71) for very low counts is added.
- 4. The nu symbol was replaced by "r".

RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Limiting Conditions for Operation l 155>< 3.18.5 Gas Storage Tanks l The quantity of radioactivity contained in each waste gas decay tank 155>< shall be limited to less than or equal to 135,000 curies of noble gases (considered as Xe-133). Applicability At all times Action 155> a. With the quantity of radioactive material in any waste gas decay tank exceeding the above limit, immediately suspend all additions of radioactive material to the tank and within 48 hours reduce the tank contents to within the limit, and describe the events leading to this condition in the next Semiannual Radioactive Effluent Release
< Report, pursuant to Specification 6.9.2.3.
Bases Restricting the quantity of radioactivity contained in each waste gas decay tank provides assurance that in the event of an uncontrolled release of the tanks contents, the resulting total body exposure to an individual at the 155>< exclusion area boundary (See Figure 5.1-1) will not exceed 500 mrem. This is consistent with Standard Review Plan 15.7.1, " Waste Gas System Failure." Potential atmospheric releases from a waste gas decay tank are evaluated assuming design coolant activities (see page 14D-25 Vol. VI FSAR). Based on
}; primary coolant activity as shown in Table 140-7, the decay tank is assumed to hold the activity associated with the off-gas from one reactor coolant system degassing with no credit taken for decay.
Calculation of the limiting decay tank activity based on the coolant activity limit of Technical Specification 3.1.4 yields a maximum decay tank inventory - of 98,414 Ci (Ref. FSAR Table 14D-23). In order for the decay tank inventory to reach the limiting condition for operation, coolant activity would have to exceed the Technical Specification 3.1.4 limit on coolant activity and this would require a reactor shutdown, thus preventing a further increase in gaseous activity. Therefore, it is conservative to require that the online waste gas decay tank 155>< be sampled daily upon reaching the reactor coolant system limiting activity value (43/E) to ensure the 135,000 curies equivalent Xe-133 is not exceeded. Once the coolant is below the limiting activity, there is no requirement to sample waste gas decay tanks except for discharging. Proposed Amendment No. 155 3-79

RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Surveillance Standards exposure-of-an individual through appropriate pathways is unlikely to be substantially underestimated. The equations specified in the ODCM for calculating the doses due to the actual release rates of radioactive materials in liquid: effluents are consistent with the methodology provided in Regulatory Guide 1.109, " Calculation of Annual Dose to Man from Routine Releases of Reactor Effluent for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977, and Regulatory Guide 1.13. " Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I," April 1977. 155- The results from composite samples during the period 1981 through 1984 indicates that Cs-137, Cs-134, Co-58 and Co-60 constitute 80 percent of the historical mix of gamma emitting radionuclides in plant liquid effluents. Another 13 percent consists of I-131. When the thyroid is separated as a limiting organ, 97.8 percent of the total body dose and 97.6 percent of the limiting organ dose are due to Cs-134 and Cs-137. Essentially 100 percent of the thyroid dose is due to I-131. The activity analysis of Cs-134, Cs-137 and I-131 at the Lower Limits of Detection specified in Table 4.21-1 are based on an estimated annual plant radioactive effluent outflow of 20 million gallons per year with an average dilution flowrate of 5,000 gallons per minute. These Lower Limits of Detection equate to an offsite dose commitment of approximately 50 percent of the guidelines specified in 10CFR50, Appendix I and provide an adequate basis for determining the presence or absence of dose due to other radionuclides in plant liquid effluents, when no other indications are revealed during sample analysis. The Lower Limits of Detection specified in Table 4.21-2 equate to an offsite dose commitment of approximately 10 percent of the 10CFR50, Appendix I guidelines. The dose tracking system ensures that the dose limits prescribed in Technical Specification 3.17.2 will not be exceeded at the 95 percent confidence level. The methodology presented in the ODCM provides for adjustment of operational and analysis parameters to factor in variables such as annual radiological liquid effluent release volume, discharge canal flow rate, and current cumulative dose. The dose tracking system provides for prompt updating of cumulative dose and contains feedback mechanisms to assure that the target dose values are not i exceeded. The tracking system also contains review and approval of batch I radiological liquid effluent releases at multiple management levels. There is also reasonable assurance that the operation of the facility will not result in radionuclides concentrations in finished drinking water that
- are in excess of the requirement of 40CFR141.
