1.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM BASES ,

The Rancho Seco Unit One Technical Specifications, Section I 4.26, state in part that: )

"The Radiological Environmental Monitoring Program required by this specification provides measurements of radiation and radioactive materials in those exposure pathways and for those radionuclides which 1 lead to the highest potential radiation exposures of individuals resulting from station operation. This monitoring program thereby supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected."

The Sacramento Municipal Utility District and the Rancho Seco Nuclear Generating Station, to ensure that this requirement is met, have instituted a Radiological Environmental Monitoring Program (REMP) which this manual serves to implement. The REMP is based upon the guidelines of Title 10 of the Code of Federal Regulations, Part 20, Section 106 (10 CFR 20.106). That Regulatory basis and associated guidelines have been the foundation of the REMP and its programmatic elements which: -i

1. Provide the technological basis of, and the instruction for, monitoring the site and environs for radioactivity of all sources, including;
a. naturally occurring background
b. releases during normal operations
c. operational occurances and postulated accidents
d. weapons testing and major nuclear accidents which contribute to detectable radioactivity in the environs.
2. Provide the mean; to verify the ef fl uent control program of the Rancho Seco Nuclear Generating Station. ,
3. Meet minimum limits for detecting radioactive elements l in samples collected from the environs, or direct measurements in the field. 1
4. Provide measurements of radiation and radioactive materials in those exposure pathways, i.e., liquid, l

2.0 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM DESCRIPTION The Radiological Environmental Monitoring Program is under the cognizance of the Chief Executive Officer, Nuclear,'with the responsibility for the administration and oversight of the program assigned to the Manager, Environmental Protection.

The design of the program is consistent with the intent of Title 10 Code of Federal Regulations, Part 20, Section 106,

" Standards for Protection Against Radiation". To implement-these requirements, the Technical Specifications, Offsite Dose Calculation Manual and Health Physics ' Implementation Procedures have been-developed. The -implementing procedures address specific areas of emphasis in the program that require direct attention and/or specified step-wise pro'gress for completion. The following is a list of those types and numbers of those documents used for the- implementation of the REMP: ,

2.1 RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM PARAMETERS l 1

The monitoring and sampling aspects of the program have been i established after three major factors were determined, which are. 3 i

Identification of the effluent release pathways, Identification of the human exposure pathways, l

Identification of the land usage parameters by the population within a ten mile radius of the site.

Three principal release pathways exist at Rancho Seco Nuclear Generating Station, which are:

Gaseous Effluents discharges from the waste gas system for the reactor building stack, auxiliary building stack, miscellaneous water evaporator stack and the auxiliary grade level vent.

Liouid Ef fluents discharges which are released from the retention basins via the waste water disposal system (regenerant hold up tanks (RHUT) A and B].

Direct Radiation radiation that emanates from radioactive material contained within tanks or other containers which are within the site boundary to humans outside of the site boundary.

The pathways to human exposure to radioactive materials in the ef'luent release pathways from Rancho Seco are:

Gaseous Inhalation of airborne radioactive material by humans, or by animals that inhale and retain the material in animal products eaten by the public, i.e. meat or milk. 1 Consumption of radioactive particulate material which, although carried by air

2.2 ANALYSIS OF EXPOSURE PATHWAYS J Exposure pathways are analyzed through a systematic process- l which identifies a sample medium or organism that is found in the effluent pathways, for which usage f actors' can be-determined and will suitably represent biological concentration, retention or uptake which may ultimately  ;

represent a contribution to human exposure. The pathways to human exposure are evaluated through the analysis of data 1 obtained from the performance of a land use census. The performance of the land use census is required ;by the Technical Specifications Section 4'.27. The' analysis of 'the effluent and exposure pathways enables the selection of l sampling and monitoring locations that fall into one of two 1 classes, those which are, and those which are not, )

influenced by ef fl uent pathways. Those in the pathways are l referred to as indicator locations. Several of the j unaffected locations are selected to represent baseline or l control locations.

l Indicator locations provide. data from the surrounding i environment that may be influenced by the operation of the plant because they are nearby, downwind or downstream in the release pathway. Such data.can be used to calculate doses to humans to verify the degree of compliance with' 40 CFR 190, using methodology contained in the 0DCM. (This is referred to as the Real Individual Exposure'. The Real Individual is defined as any person who participates- in activities that result in that -person being in the actual pathways for offsite dose. A Real Individual' who, based upon the land use census, is expected to receive the maximum offsite dose to real individuals, may be used to calculate doses to-demonstrate compliance with 40 CFR 190).

Control sample locations are to provide data that should not be influenced by the operations of Rancho Seco. These locations are selected based upon the . distance from the plant, being upwind, or upstream of the release. pathways.

Data from these locations help discriminate between Rancho Seco rel. eases and other natural or manmada events that may impact human exposure.

At Rancho Seco, potentially radioactive liquid effluent is discharged into Clay Creek. Continuously, a minimum flow of 5000 gallons per minute of non-radioactive water is released above the discharge point. The continuous minimum flow and-the liquid radioactive e f fl uent release are - the major effluent' release pathway, and hence exposure pathway for.the

'PAGE 11 0F'27 station during normal operations'. . Prior: to .the . minimum -

release rate being established, Clay Creek was a seasonal stream, formed as the confluence of. three and~ - one .hal f square miles .of drainage runoff u'pstream of the site. The now continuous flow of . Clay Creek intersects Hadsilv111e Creek North and West o f. California State Highway 104.

Hadselville . Creek ' intersects Laguna Creek just East of the-Folsom Canal. Laguna Creek flows into the Consumnes' . Rive.r approximately 20 mi'les from: Rancho Seco. Hadselville and Laguna Creeks .are also seasonal streams .and also . receive irrigation runoff during periods when i rri g ati o_n i s - used.

Because these streams are the major release pathway for:

liquid effluents from the site, the. majority. of' recent program enhancements have focused on this. effluent pathway.

The gaseous pathway. analysis is-also:related.to the. land use census. This pathway is not confined by creek banks, but11s  !

subject of the meteorological conditions during the time of~

the release. This presents 'the' requirements o f. having indicator and control sampling stations more evenly distributed with .particular . attention to those areas -of greater population density. While not the major' release nor  ?

exposure pathway, recent improvements in monitoring this pathway have been instituted.,

The direct radiation exposure pathway is the' least likely:

pathway for the exposure to plant radiation by humans. It.is the most easily measured with the use -of -thermoluminescence dosimeters, which monitor continuously and passively. The dose is integrated over three months 'to accumulate a statistically significant exposure-. The vast majority-of the dose integrated- by -these detectors is delivered from primordial elements in the geological surface of the Earth, which happen to contain naturally radioactive elements. A smaller fraction of the dose- is delivered .by cosmic radiation which has penetrated the Earth's atmosphere.

2.3 IDENTIFICATION OF SAMPLING AND MONITORING SITES AND SAMPLES Sampling and monitoring sites and the samples co11ected from them, must be - identi fied with a concise designation. This has been accomplished using the following methodology':

To establish the Utility identification, the letter "R" has been chosen. Therefore all samples-from the Rancho Seco begin with the letter "R".

Next, that portion of the identification related to.the type of sample is made with a two letter designation,

'I

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM MANUAL REVISION: 1 PAGE 12 0F 27 l l

i.e., AS = Air Sample. A complete list is contained in <

Tabl e 1.  !

l A group of digits follows the Sample type. These  !

indicate the straight-line distance from the center of  !

containment. For distances less than ten miles, the figure is to the nearest tenth of one mile. For distances ten or more miles the figure is to the nearest mile. Distances are measured with the use of U.S. Geodetic Survey maps.

Following that is a letter designation which specifies the identification letter corresponding with one of the 16 wind sectors as identified in the Emergency Response Plan, i.e., "H". Emergency Response Plan Wind Sectors i are defined in Table 2.

The final character is the letter "0" which designates the sample as being one collected after the plant was 3 declared operational. 1

{#

Thus, a Rancho Seco Air Sample, collected at ten miles from the plant in Emergency Plan Wind Sector "H" after operational status was established would be -identified as:  !

RAS 10H0.

To complete the identification process, each sample  !

label has a date as part of the sample number, followed by 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> time, written as:

HM/DD/YYYY-HHmm, or specifically, if the sample was collected in December, on the 15th day in 1987 at 5:15PM, then the above sample would be identified as: ,

RAS 10H0-12/15/1988-1715.

The present system of identification has been incorporated in preference to the system originally used to identify ,

samples and sites. There is a necessity to retain the ability to identify, and continue to use data from, previously collected samples. The former identification designation is shown in parenthesis under the currently used one.

F RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM MANUAL REVISION: 1 PAGE 13 0F 27 2.4 REPORTING RESULTS OF RADIOLOGICAL ENVIRONMENTAL DATA The requirements for reporting radiological environmental data are specified in the Technical Specifications, Section 6.9.2, Environmental Reports. Those subsections which require supporting data from the Radiological Environmental Monitoring Program Address the Annual Radiological Environmental Operating Report and the Semi-annual Radioactive Effluent Release Report. Technical Specification Section 6.9.5, Special Reports, is made specific in HPIP 2050, Radiological Environmental Reports. Specified therein are conditions requiring special reports, and reporting requirements in days for submittal. This includes those calculations to provide rapid assurance of the degree of compliance with 10CFR50 Appendix I, and 40CFR190 calculations after releases of any origin.

2.5 SELECTION OF RADIOLOGICAL ENVIRONMENTAL MONITORING LOCATIONS In conjunction with the data base established from the land use census, the requirements of the Technical Specifications, and the guidance described in Section 2.0 of this Manual, the selection of sampling and monitoring sites was performed. These were chosen to provide for at least the minimum number of indicator locations specified in Technical Specifications, Section 3.22, Table 3.22-1.

For those locations to be classified as indicator sites, data is gathered from the land use census, Lawrence Livermore National Laboratory Rancho Seco Study Reports, Oak j Ridge National Laboratory Study Reports, and from additional 6 sampling sites from which materials have been collected and j determined to be candidate sites. Presently, a sufficient ,

number of control sites have been selected and are not l anticipated to be increased in number.

l Environmental thermoluminescence dosimeters are placed more  !

uniformly around the environs of the site. These devices  !

passively monitor radiation in the immediate environs. Data from TLDs is trended to establish variations which are l j

influenced by seasonal, meteorological, local and global j sources. TLDs will also respond to radiation in the j effluents of the plant if they pass in near proximity.

The TLD Program is operated entirely by Rancho Seco. The data is included in each Quarterly Environmental Report.

Representative samples of all the pathways and suitable  !

locations are established in all directions. Air samplers are distributed to achieve a sampling of air from major wind i directions across the site, j The R ad i ol og i c a'l Environmental Monitoring Program maintains at least those minimum sampling locations and type of .

samples as required to meet the Technical Specification l requirements listed in Table 3.22-1. Many sample types and locations have been added to enhance characterizing. the radiological 9 environmental impact of Plant operations. The increased sample locations and types in this manual, will be will be maintained unless it is determined that they are no longer useful or necessary data sites. The number and type will not be reduced below those stated in T.S. 3.22-1.

Two special sites that have been established are vegetable l gardens maintained by site personnel. One is established at  !

the site boundary alongside the Clay Creek, and irrigated  !

with water from the e f fl uent stream. These data are considered essential for comparisons to vegetation not irrigated with effluent stream water for determination of bioaccumulation for soil types common to the environs. The second garden is at the North of the site, and is irrigated with domestic water. Washed vegetable from this sight will .

be compared to the site boundary washed vegetables for the l comparison studies. Unwashed Samples will be taken from this garden to evaluate possible airborne materials to the North i of the site via the gaseous effluent exposure pathway. j l
