Davis-Besse Nuclear Power Station Jan. - June 1989 The Semiannsi Report Summary

)

The Semiannual Effluent and Waste Disposal Report is a detailed listing of radioactivity released from the Davis-Besse Nuclear Power Station within a six month period. This report, for the January 1 - June 30,1989 period, differs from previous semiannual reports in that it was prepared primarily for technically-oriented readers (specifically, the Nuclear Regulatory Commission and fellow

)' industry members), and does not include basic background information found in reports from the past two semiannual periods. Generic information about topics discussed in this and future semiannual reports will be presented in less technical language in future Annual Environmental Operating Reports. These reports are available to the public in many local and university libraries.

This report provides the following information for the period January 1 through June 30,1989:

. Summation of the qutntities of radioactivity released in gaseous and liquid effluents."

) i of the quantities of radioactivity cargained in

. Summat on solid waste packaged and shipped for offsite disposal et federally approved sites.

• Changes to the Offsite Dese Calculation Manual (ODCM).

• Changes to Radiological Environmental Monitoring Program sample collection locations listed in the ODCM.

) Most of the radioactivity associated with an operating nuclear power station is contained within the station itself. However, during normal operation, a small amount of radioactivity is found in gaseous and liquid wastes. The station's waste

. '(

The Semiannual Report Jan. - June 1989 Davis-Besse Nuclear Power Station processing systems provide for the storage and recycling of wastes, and removal of most of the radioactivity present. The U.S. Nuclear Regulatory Commission (NRC) requires nuclear power stations to be designed, constructed and operated so that the amount of radioactivity released to unrestricted areas (areas outside the site boundary) is kept "as low as reasonably achievable," 3r ALARA. To en-sure this objective is met, both the NRC and Davis-Besse have established limits governing the release of radioactivity.

The radiation dose to the public is calculated for each release using the con-centration of radioactivity and the weather conditions present at the time of the release. During the period of January 1 through June 30,1989, the maximum in- (

dividual offsite dose due to radioactivity released in effluents was approximately:

Davis-Besse Nuclear Power Station Jan. - June 1989 The Semiannual Report during this semiannual period was approximately 0.03 mrem from liquid releases. This represents approximately 1% of the Technical Specifications limit.

fluents from the Davis-Besse Nuclear Power Station for the latest reporting period is 1400 times lower than the dose the average individual in the Oak Har-bo.r, Ohio area received from natural background sources during the same time period. Whole body dose due to natural background sources (cosmic and ter-restrial) averages about 13 mrem per quarter in the Oak Harbor area. The average equivalent dose in the United States from natural radon is about 50

The SemiannualReport Jan. - June 1980 Davis-Besse Nuclear Power Station

~ In 1981, mechanical damage to two steam generator tubes resulted in a small amount of radioactive water leaking into the secondary system. Some of this water from the secondary side was released in station effluents. This caused an increase in the radioactivity released in effluents. However, the resulting dose to the public was less than 50% of the Technical Specifications dose limits. . The in- -

creased offsite doses in 1984 and 1985 were associated with the liquid radioac- (

tive waste processing methods . As in 1981, the resultant doses were substantially less than the Technical Specifications limits.

Prior to January 1,1989, a small leak appeared in one of the two steam gener-ators, and continued throughout the reponing period. Although the steam gener- (

ator leak occurred before January 1,1989, it had no significant impact on effluent releases during earlier reporting periods, and therefore was not dis-cussed in previous Semiannual Effluent and Waste Disposal, Reports.

. The steam generator leak is specifically identified in this report because attempts - -(

to Iccate the leak during the previous refueling outage were unsuccessful due to the small size of the leak. Despite its small size, the leak allowed a small fraction of the radioactivity present in the pnmary coolant to be transferred to the secon-dary loop.

(

Although the steam generator leak has contributed to the total whole body dose to the public during this six-month period, the whole body dose has remained less than 3 % of the quarterly Technical Specifications limits. At all times the water in the tertiary loop (leaving the cooling tower) has remained non radioactive.  ;<

Gaseous Effluents Radioactivity released in gaseous effluents from Davis-Besse is classified into

)

two categories:

• Noble gas e Iodine-131, tritium, and particulatns with half-lives greater than eight days

) During the first six months of 1989,162 curies of noble gas and 9.1 curies of iodine-131, tritium, and particulate with half-lives greater than eight days were released in gaseous effluents. The resulting whole body dose from these releases was less than 0.5% of the Davis-Besse Technical Specifications dose limits for gaseous effluents during the first two quarters of 1989 (See Table 2).

)

Liquid Efflue,;.s Radioactivity in liquid effluents consists of dissolved and/or suspended radioac-i tive fission and activation products, trinum, and entrained gasser.. During the

) first and second quarters of 1989, approximately 0.16 curies cf fission and activa-tion products,78.4 cur:6s of tntium, and 0.09 curies of dissolved and entrained gases were released in hquid effluents. The results.nt whole body dose due to the ,

radioactivity present in liquid effluents was approximately 1% of the limits set by I the Davis-Besse Technical Specifications. Table 3 summarizes the doses due to

) radioactivity released in liquid effluents during the the first two quarters of 1989.

Solid Waste Shipments

Davis-Besse Nuclear Power Station Jan. - June 1989 The Semiannual Report waste storage facility. The shipments consisted of 23.3 cubic meters of waste such as spent resins,51ter sludges, and evaporator bottoms; and 26.1 cubic meters of dry compressible waste, such as cotton work gloves and paper coveralls, and contaminated equipment. The total activity of the shipments com-bined was 1.37 curies. Table 6 of Appendix B provides greater detail of the solid

)

waste shipments during the first and second quarters of 1989.

Radiologicalimpact of Davis-Besse

) Routine nuclear power station operation normally results in releases of small concentrations of radioactivity in liquid and gaseous efflueras. These effluents are closely monitored before and during release, and are limited by federal regulations. Over time, the small concentrations of radioactive materials in the effluents naturally decay into non-radioactive substances.

)

The annual dose to the public due to operation of Davis-Besse is typically several orders of magnitude less than the annual dose the average American receives from background sources. In fact, even if Davis-Besse reached 100% of the federallimits for radioactive releases, the dose to the public would still be less than the average dose due to background sources.

)

For the period January 1 through June 30,1989, the maximum whole body dose to the public was less than 3% of the quarterly limits set by the Davis-Besse Technical Speci5 cations. Since operation began in 1977, Davis-Besse has had no significant radiologicalimpact on the surrounding environment.

6. ABNORMAL RELEASES There were nine abnormal releases during the semiannual period of January through June, 1989. The activity released, as well as the projected doses are maximum calculated values.

(

Each release is summarized below. The concentrations of radioactivity released and the meteorological data for these releases have been included in the appropriate tables in this report. The projected doses for these releases were well below the Davis-Besse Technical Specifications limits. (

A. First Quarter Auxiliary Feed Pump During the first quarter of 1989, steam containing radioactivity from the secondary cooling system vas released through the auxiliary feed pump exhaust. During periodic testing'of these pumps, the steam used (

for their power source is emitted through the vents. The total activity released was 5.66E+01 mci. The highest projected offsite dose is 3.56E-06 millirem to the thyroid of an adult at the receptor location for the duration of the testing for a quarter year. This is less than one thousandth of one percent of the Davis-Besse quarterly Techniccl Specifications limit. (

B. January Main Steam Safety and Atmospheric Vent Valve Systems In January 1989, steam containing radioactivity was released through the main steam safety system and through the atmospheric vent valve system during pressure reduction in the secondary cooling system. The total (

activity released was 1.10E+01 mci. The highest projected offsite dose is 5.93E-04 millirem to the thyroid of a child at the most restrictive receptor location in the NE sector, which is well below the Technical Specifications limit.

C. March Atmospheric Vent Valve System (

In March 1989, steam containing radioactivity was released through the atmospheric vent valve system during pressure reduction in the secondary cooling system. The total radioactivity released was 7.07E+01 mci. The highest projected average dose rate was 4.71E-01 millirem per year at the site boundary (inhalation dose rate to a child thyroid in the VNV (

sector). This is less than 0.1 percent of the Davis-Besse Ounrterly Technical Specifications limit. The highest cumulative tetal body dose van 9.0E-04 millites to an adult in the W sector at 870 meters from the release point. This dose is itss than 1.4E-02% of the Davis'-Basse qusrterly Technical Specifications limit for this pathway. Tne highest organ dose for this release was 1.3)E-02 millires, which is (

approximately 1.9E-04% of the quarterly Technical Specifications limit.

D. First Quarter Atmospheric Vent Valve System During the first quarter of 1989, steam containing radioactivity was released through the atmospheric vent valve system due to leakage from (

a

) v th2 s:cendary c:311rg systcm. During normal operations a small fraction 1 of the steam produced in the steam generators is lost due to Jeaking atmospheric vent valves and emitted through the vents. The total i

{

activity released was 4.66E+02 mci. The highest projected offsite dose is 3.91E-05 millirem to the thyroid of a child. This is less than one

}' thousandth of one percent'of the quarterly Technical Specifications limit.' j E. Second Ouarter Atmospheric Vent VP.lve System

)

During the second quarter of 1989, steam containing radioactivity was released through the atmospheric vent valve system due to leakage from the secondary cooling system. During the second quarter, a total activity of 8.99E+02 mci was released via the leakage.

The highest projected offsite dose is 1.98E-04 millirem to the thyroid

)

of a child. This is less than 3.0E-03 percent of the quarterly Technical Specifications limit.

F. Second Quarter Auxiliary Feed Pump During periodic testing of the auxiliary feed pumps in the second 3

quarter of 1989, steam containing radioactivity from the secondary cooling system was released through the auxiliary feed pump exhaust. A total activity of 9.12E+01 mci was released. The highest effsite dose projection was 2.4E-05 millitum to a child. This is less than 3.0E-03 percent of the quarterly Technical Specifications limit.

G. June Seal Injection Filter Leakage on June 1, 1989, a buildup of noble gas in the fuel handling building, as a result of leakage from the seal injection filter, was discovered.

The noble gas was released via the station vent. The total activity released was 1.49E+03 mci. The highest projected offsite whole body dose is 3.61E-03 millirem, which is less than one thousandth of one

) percent of the Technical Specifications limit.

H. Second Quarter Liqvsd Release Via the South Settling Basir!

During the second quarter of 1969, vater containing radioactivity from the secondary cooling sycter: vas released to the south settling basin

)

and subsequently to La' / e Erie.. A total activity released was 7.21E+03 mC1. The calculated dose is extremely small when compared to the dose 1 Limits for the liquid release pathvay. The highest dose to any organ tc cahuhtc:! te tc 1.f333 millirca r) sht thyscid. This dose is approximately 3.3E-02 percent of the quarterly Technical Specifications limit.

This evaluation was based on the 1980 censust the Agricultural Ministry of Ontario 1980 report entitled, " Agricultural Statistics and Livestock' Marketing Account, 1980"; the Agricultural Ministry of Ontario 1980 report entitled, " Agricultural Statistics for Ontario - 1980 Publication.

)' Appendix B (of this report) Table 7 Section A, presents the maximum dose computed from the noble gas effluents for each quarter and the dose resulting from gaseous iodine, tritium, and particulate effluents.

Doses resulting from liquid releases are presented in Appendix B, Table 7, Section B.

DOSE TO PUBLIC DUE TO ACTIVITIES INSIDE TEE SITg BOLREDARY In accordance with Technical Specification 6.9.1.11, the Semiannual Effluent and Vaste Dispess.1 74 port submitted within 60 days after January 1 of each year shall include an assessment of radiation doses from radioactivity released in liquid and gaseous effloents to members of the public due to

) their activities inside the site boundary.

In special instances, members of the public Bre permitted access to the radiologically controlled area vithin the Davis-Besse station. Tours for the public are conducted with the assurance that no individual vill receive un appreciable dose (i.e., not more than a small fraction of the 40 CFR 190

) dose standards).

The Visitor Center located inside the Davis-Besse Administration Building (DBAB) is also accessible to members of the public. Considering the frequency and duration of the visits, the resultant dose vould be a small fraction of the calculated maximum site boundary dose. The dose from gaseous effluents as

' Meteorological Monitoring Meteorological data collected onsite for the period of January 1, 1989 through 7

June 30, 1989 vere reduced, validated, summarized for analysis, and included in the appropriate dose calculations. The Meteorological Monitoring System is instrumented for.vind speed, vind' direction, and temperature at 340 feet (100 meters), 250 feet (75 meters) and 35 feet (10 meters). Dev point temperatures-are measured at 340 and 35 feet. Precipitation is gathered at ground level. In addition, differential temperatures (Delta T) are measured between 340 to 35'

5.0 ASSESSMENT OF LAND USE CENSUS DATA A land use census (LUC) is conducted annually in the vicinity of the Davis-Besse site. This census fulfills two main purposes: 1) meet require.?ents of TS I

3.12.2 (as required by 10 CFR 50, Appendix I, Section IV.B.3) for identifying controlling location /pathvay for dose assessment of TS 3.11.2.3; and 2) provide data on actual exposure pathvays for assessing realistic doses to MEMBERS OF THE PUDLIC.

) 5.1 Land Use Census as Required by TS 3.12.2 ,

As required by TS 3.12.2, a land use census shall be conducted during the #

growing season at least once per twelve months. The purpose of the census is to identify within a 5 mile distance the location in each of the 16 meteorological sectors of the nearest milk animal, nearest residence and nearest garden larger

)

than 500 ft* producing broad leaf vegetation. The census shall be conducted by either a door-to-door survey, aerial survey, or by consulting local agricultural authorities (or a combination thereof). The data from the LUC is used for updating the location / pathway for dose assessment and for updating the Radio-logical Environmental Monitoring Program.

) If the census identifies a locatien/ pathway (s) yielding a higher potential dose to a MEMBER OF THE PUBLIC than currently being assessed as required by TS 3.11.2.3 (and ODCM Section 3.6 and table 3-3), this nev location / pathway (s) shall be used for dose assessment. Tables 3-2 and 3-3 shall be updated to include the currently identified controlling location /pathvay(s). Also, if the census identifies a location (s) that yields a calculated potential dose (via the

) same exposure pathway) 20% greater than a location currently included in the Radiological Environmental Monitoring Program, the new locations (s) shall be added to the program within 30 days if samples are reasonably obtainable. The sampling locations (s) excluding control locations, having a lover calculated dose via the same pathway may be deleted from the program at the time the new location /pathvay(s) is added. As required by TS 3.12.2 and 6.9.1.11, the new

) location /pathvay shall be identified in the next Semiannual Radioactive Effluent Release Report.

The following guideline shall be used for assessing the results from the land use census to ensure compliance with TS 3.12.2.

B. Relative Dose Significance B.1 For all new locations, the relative dose significance vill be

. determined by applicable pathways of exposure.

B.l.1 Relative dose calculations should be based on a generic radionuclides distribution (e.g., Davis-Besse USAR gaseous effluent source term of (

past year actual effluents). An I-131 source. term dose may be used for assessment of the maximum organ ingestion pathway dose because of its overwhelming contribution to the total dose relative to the other particulate radionuclides.

B.I.2 The pathway dose equations of the ODCM should be used. (

C. Data Evaluation C.1 The controlling location used in the ODCM Table 3-3 vill be verified.

If any location / pathway (s) is identified with a higher relative dose, (

this location /pathvay(s) should replace the previously identified controlling location / pathway in Table 3-3. If the previously identified controlling pathway is no longer present, the current controlling location / pathway should be determined.

C.2 Any changes in either the controlling location / pathway (s) of the ODCM (

dose calculations (Section 3.7 and Table 3-3) or the Radiological Environmental Monitoring Program (ODCM Section 6.0 and Table 6-1) shall be reported to NRC in accordance with TS 3.12.2, Action Item a. and b, and TS 6.9.1.11.

5.2 Land Use Census to Support Realistic Dose Assessment (

The Land Use Census (LUC) provides data needed to support the special dose analyses of the ODCM.

Levar Limit of Detection--D2ccy Correcticn Factor  !

The equation and definition of the lover limit of detection in the NRC Standard-

); Radiological-Effluent Technical Specification include the term e

• vhich is used to decay correct the analysis.. The LLD is further defined as an a priori .{

(before the fact) limit representing the capabilities of a measurement system j and not an a posteriori (after the fact). limit for a particular measurement. '

) .

Providing a decay correction for an evaluation of the capabilities of a system does not appear appropriate. It may be appropriate to decay correct certain analyses of specific samples to determine radionuclides concentrations at the time of release. Even in this case, such a correction is not appropriate for batch releases. Analyses are performed prior to any release; and, the sample vill be decaying at the same rate as the batch from which the sample vas taken. -

For continuous releases, decay correcting analyses of samples obtained over a specified sampling interval must take into account the accumulation of

)

radioactivity in the sampling medium, the decay during the sampling interval and, especially for short lived radionuclides, equilibrium or quasi-equilibrium conditions that may be achieved.

)

Short-lived radionuclides vill tend to reach an equilibrium value in the sampling medium as a function of source input and half-life. A single decay correction to adjust for sampling interval vill provide an unacceptable overestimate. Equilibrium concentrations must be considered if analyses are to

)

be indicat e of actual release quantities.

Employing exp (-Aot) to adjust for radioactive decay between the end of sampling and the time of analysis is straightforward. However, to attempt to use the same

)

term to adjust the decay during the sampling period is not p;*,ser. As a practical matter, when the half-life of a radionuclides is long relative to the sampling time and the time between sampling and analysis, i.e., minimal decay, the correction term vill be near unity. In that event, the correction term is

)'

relatively unimportant.

! 'At th2 othar extrere, wh:n tha half-lifo of a radienuclids is much shorter than-the sampling time or the time between the end of sampling and the analysis, the term exp(-Aot) could be used to adjust for decay between the end of sampling and the analysis. However, it would not be appropriate in that case to use the same (

term to attempt to adjust for decay during sampling.

The relationship between the radioactivity in a sample at the end of sampling and activity concentration in the medium being sampled is somewhat more (

involved. To explain this in the simplest condition, assume the radionuclides concentration is constant in the medium being sampled and that the medium is sampled at a constant rate.

(

In the instance of water sampling, the relationship between the activity concentration in the water being sampled and the activity concentration in the water sample at the end of sampling is:

vhen A t >> 1, C = C At 1 2 In the separate case of sampling a radionuclides in air by filtering the air and analyzing radioactive material collected on the filter, the radionuclides of (

interest is concentrated. Absent diluent air in the sample being analyzed, the relation between radioactivity on the sample media and radionuclides concentration in the air being sampled is:

q = Cg F (1-e- t) (2) C A

)'

vhen A t >> 1, C, = q A/F.

'This merely recognizes that the rate of loss from the filter by radioactive

): decay equals the rate of collection onto the filter at equilibrium.

The NRC proposed. equation appears to incorporate an adulterated vay of encouraging analysis soon after the end of sampling and to encourage efficient

)r sample concentration or radiochemical extraction. Although not rigorous, it combines both objectives in a simple and thus practical way, provided the decay correction is not extrapolated to a time earlier than the end of sampling.

y A more nearly rigorous way of determining the activity concentration (or minimum detectable activity) in the medium being sampled is to assess the LLD in the sample at the time of analysis. Then the activity concentration in the medium being sampled can be calculated with the product of exp(-Aot) for decay between r

the end of sampling and the analysis and one of the equations derived herein for the relation between the medium being sampled and the activity in the sample at the end of sampling.

y However, this method is not very practical or necessary considering the types of sampling and analysis at nuclear power plants, the significant radionuclides, and the offsite potential doses. The bulk of radioactivity is released as batch releases with all sampling and, analysis performed prior to release. Therefore, y no decay corrections are applicable. It is in the sampling and analysis of continuous releases that the accumulation and decay of the radioactive material may need to be considered. The use of NRC's guidance for decay correction to the mid-point of the sampling period can grossly overestimate actual release y qualities of short-lived radionuclides, while providing little improvement for Davis-Besse, Unit 1 J-11 Revision 3.1, 1989 D-9

Overall,-it may be appropriate to decay correct a certain analysis to account -

for radionuclides decay during the sampling period. However, simple decay correction to the mid-point of sampling vill grossly overestimate any short-lived radionuclides that may be detected. More consideration needs to be given by the NRC to address this problem. In any. case, the use of a decay

(

correction factor in defining a lover limit of detection is inappropriate. The LLD is a measurement of the capability of the measurement system and should not be used to try to establish a regulatory position on sampling and decay correction for quantification of releases.
