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 toples

( 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:  ;

l e Summation of the quantities of radioactivity released in '

gaseous and liquid effluents. I h e Summation of the quantities of radioactivity contained in solid waste packaged and shipped for offsite disposal at federally approved sites. -

. Changes to the Offsite Dose Calculation Manual (ODCM).

e Changes to Radiological Emironmental Monitoring Program sample collection locations listed in the ODCM.

j 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 processing systems provide for the storage and recycling of wastes, and removal of most of the radioactivity present. The U.S. Nuclear Regulatory Commission 3 (NRC) requires nuclear power stations to be designed, constructed and operated so that the amount of radioactivity released to unrestricted areas (areas outside O

l '- The Semlannual Report, Rev.1 Jan. June 1989 Davis Besse Nuclear Power Station (

Ol the site boundary) is kept "as low as reasonably achievable " or ALARA. To en- I 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- el I centration of radioactivity and the weather conditions present at the time of the release. During the period of January 1 tnrough June 30,1989, the maximum in- -

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

e 0.03 mrem, whole body O e 0.04 mrem, liver Gaseous Effluents:

Noble Gas:

e 0.003 mrem, whole body g:

e 0.008 mrem, skin lodine 131, tritium, and particulates with half lives greater than 8 days:

e 0.002 mrem, whole body e 0.05 mrem, thyroid 9; These doses are only a small fraction of the limits set by the Davis Besse Techni -  ;

cal Specifications (see "Ihble 1). The highest whole body dose to the public during this semiannual period was approximately 0.03 mrem from liquid releases. This represents approximately 1% of the Technical Specifications limit.

i The maximum hypothetical whole body dose received by any individual from ef- i fluents from the Davis Besse Nuclear Power Station for the latest reporting i period is 1400 times lower than the dose the average individual in the Oak liar-bor, 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 liarbor area. The average equivalent dose in the United States from natural radon is about 50  !

mrem per quarter, for a total of approximately 252 mrem per year from back- l ground sources. l Figure 1 presents a comparison of the Davis Besse Technical Specifications dose limits and the doses due to effluents released from Davis Besse since operation began in August,1977 through the end of the second quarter of 1989.  !

water from the sJcondary side was released in station effluents. This caused an  !

e increase in the radioactivity released in effluents. However, the resulting dose to i L 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. l tive waste processing methods , As in 1981, the resultant doses were el substantially less than the Technical Specifications limits. j R Prior to January 1,1989, a small leak appeared in one of the two steam gener-i .- ators, and continued throughout the reporting period. Although the steam gener- l ator leak occurred before January 1,1989,it had no significant impact on g) l- effluent releases during earlier reporting periods, and therefore was not dis- j i cussed in previous Semiannual Effluent and Waste Disposal Reports. l l

The steam generator leak is specifically identified in this report because attempts to locate the leak during the previous refueling outage were unsuccessful due to g) l the small size of the leak. Despite its small size, the leak allowed a small fraction L of the radioactivity present in the primary coolant to be transferred to the secon- I dary loop. -

l 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 i

less than 3 % of the quarterly Technical Specifications limits. At all times the J water in the tertiary loop (leaving the cooling tower) has remained i non-radioactive.

. Gaseous Effluents Radioactivity released in gaseous effluents from Davis-Besse is classified into l two categories:

e Noble gas f

e lodine-131, tritium, and particulates with hal'-lives greater than eight days During the first six months ,of 1989,162 curies of noble gas and 9.1 caries of

)

iodine 131, tritium, and particulates 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 Effluents

{

Radioactivity in liquid effluents consists of dissolved and/or suspended radioac- i tive fission and activation products, tritium, and entrained gasses. During the  ;

5 first and second quarters of 1989, approximately 0.16 curies of fission and activa-  !

[ tion products,78.5 curies of tritium, and 0.09 curies of dissolved and entrained l j gases were released in liquid effluents. The resultant 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 f radioactivity released in liquid effluents during the the first two quarters of 1989.

Solid Waste Shipments

l waste storage facility. The shipments consisted of 23.3 cubic meters of waste such as spent resins, filter sludges, and evaporator bottoms; and 26.1 cubic meters of dry compressible waste, such as cotton work gloves and paper L 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.

i RadiologicalImpact of Davis-Besse '

Routine nuclear power station operation normally results in releases of small concentrations of radioactivity in liquid and gaseous effluents. 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 c

federal limits 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 quarterlylimits set by the Davis-Besse Technical Specifications. Since operation began in 1977, Davis-Besse has had no significant radiological impact on the surrounding environment.

6. ABNORMAL RE12ASES:

There were nine abnormal releases during the semiannual period of January throughEJune, 1989. The activity released, as well as the '

projected doses are maximum calculsted values. GD; 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. IDi A. First Quarter Auxiliary Feed Pump ,

During the'first quarter of 1989, steam containing radioactivity from

-the secondary cooling system was released through tne auxiliary feed pump exhaust. During periodic testing of these pumps, the steam used ID.

for their power source is emitted through the vents. The total activity released was 5.66E+01 mC1. 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 Technical Specifications limit. GI 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 IDi

> 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.

l C. March Atmospheric Vent Valve System GD 7

In March 1989, steam containing radioactivity was released through the atmospheric vent valve system during pressure reducticn 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 ID.'

sector). This is less than 0.1 percent of the Davis-Besse Quarterly Technical Specifications limit. The highest cumulative total body dose ,

was 9.0E-04 millirem to an adult in the N sector at 870 meters from the #

release point. This dose is less than 1.4E-02% of the Davis-Besse quarterly Technical Specifications limit for this pathway. The highest organ dose for this release was 1.39E-02 millirem, which is ID' 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 II A-4 ID l

3 ' )

9 i the secondary cooling system.

~

During normal operations a small fraction of the steam produced in the steam generators is lost due to leaking atmospheric vent valves and emitted through the vents. The total activity released was 4.66E+02 mci. The highest projected of fsite dose

) ,, is 3.91E-05 millires to the thyroid of a child. This is less than one thousandth of one percent of the quarterly Technical Specifications  !

-limit.

E. Second Quarter Atmospheric Vent Valve 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 l activity of 8.99E+02 mci was released via the leakage, i l

The highest projected offsite dose is 1.9BE-04 millirem to the thyroid of a child. This is less than 3.0E-03 percent of the quarterly Technical Specifications limit.

i P. Second Quarter Auxiliary Feed Pump During periodic testing of the auxiliary feed pumps in the second quarter of 1989, steam containing radioactivity from the secondary cooling system was released through the auxiliary feed pump exhaust. A 1 total activity of 9.12E+01 mci was released. The highest offsite dose projection was 2.4E-05 millirem 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 f 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.

i H. Second Quarter Liquid Release Via the South Settling Basin During the second quarter of 1989, water containing radioactivity from the secondary cooling system vas released to the south settling basin and subsequently to Lake Erie. A total activity released was 7.21E+03 mC1. The calculated dose is extremely small when compared to the dose limits for the liquid release pathway. The highest dose to any organ vas calculated to be 1.63E-03 millirem to the thyroid. This dose is approximately 3.3E-02 percent of the quarterly Technical Specifications

) limit.

I. Second Quarter Liquid Release via the Training Center Pond l During the first and second quarters of 1989, water containing racioactivity was released to the onsite Training Center Pond. In the second quarter, the Training Center Pond water flowed to Pool U of the A-5

I

+

O.;

Davis-Besse Marsh and then was released to the Toussaint River. This water was frem a normal flow path from the turbine building sutrp and drainage from the auxiliary boiler system. The Icv activity l' cor. centration detected in this water was due to minor leakage from the primary to the secondary system that existed during this period. Si A total volume of 1.73E+07 gallons was conservatively estimated to have been released to the Toussaint River. This estimation was based on the assumption that pumps at the release point were operating at maximum l

output during the entire release period of 288 hours0.00333 days <br />0.08 hours <br />4.761905e-4 weeks <br />1.09584e-4 months <br /> between June 16 and Jur.e 28, 1989. The estimated activity released was 5.44E+01 mC1. The O.

' highest projected of fsite whole body dose was 1.86E-04 millirein, which is 1.2E-02% of the quarterly Technical Specifications limit.

Activity concentrations and the' corresponding dose for each of the L radionuclides identified by analysis were calculated in accordance with the methodology of the Offsite Dose Calculation Manual (0DCM). To 0:

determine the activity concentration of Pool #3,'a sample was taken from -

the-auxiliary boiler and applied to a mathematical model based on r corrpartmental flow from~the auxiliary boiler. Neither physical l settlin',gbioaccumulation, or evaporation vere considered it was i

assumed that all tritium and lodine remained in solution with the initial activity concentration of each pool equal to zero. The activity 9-was decay-corrected in the model to account for both hold up and flov

! duration from pond to pond. The calculated activity concentration values, along with volume estimates and a release duration vere then entered into ODCM equation 2-10, and a conservative offsite dose value i var calculated.

DOSE TO PUBLIC DUE TO ACTIVITIES INSIDE THE SITE BOUNDARY In accordance with Technical Specification 6.9.1.11, the Semiannual Effluent and Vaste Disposal Report submitted within 60 days af ter January 1 of each i

' year shall include an assessment of radiation doses from radioactivity O released in liquid and gaseous effluents to members of the public due to '

their activities inside the site boundary. '

'In special instances, members of the public are permitted access to the radiolegically controlled area within the Davis-Besse station. Tours for the public are conducted with the assurance that no individual vill receive O, ~

an 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 s nal'. f raction of the O' l

calculated maximum site boundary dose. The dose from gaseous effluents as '

modeled for the DBAB Visitor Center is considered the controlling factor when evaluating doses to members of the public from activities inside the site boundary. For purposes of assessing the dose to members of the public lu accordance with Technical Specification 6.9.1.11, the following exposute assumptions may'be used: g

- Exposure time for maximum exposed visitor of 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> (4 visits. 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> per visit).*

- Annual average meteorological dispersion (conservative, default use of maximum site boundary dispersion). g The equations in the ODCH may be used for calculating the potential dose to a member of the public for activities inside the site boundary. Based on these assumptions, this dose would be at least a factor of 400 less than the maximum site boundary air dose as calculated in the ODCM.

g.

l There are no areas onsite accessible to the public where exposure to liquid effluents could occur. Therefore, the modeling of the ODCM conservatively estimates the maximum potential dose to members of the public.

10. INOPERABLE RADIOACTIVE EFFLUENT MONITORING EQUIPMENT g

There was no radioactive effluent monitoring equipment, required to be operable by Davis-Besse's Technical Specifications Sections 3.3.3.9 and l 3.3.3.10, inoperable for more than 30 days.

Noteorological Monitoring Meteorological data collected onsite for the period of January 1, 1989 through 9 Junt 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 Q feet and 250 to 35 feet. Delta T's are classified into Pasquill stability classifications using the following table.

)o 5.0 A_SSESSMENT OF LAND USE CENSUS DATA I l

A land use census (Lt'C) is conducted annually in the vicinity of the Davis-Besse I site. This census fulfills two main purposes: 1) meet requirements of TS 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 i data'on actual exposure pathvays for assessing realistic doses to MEMBERS OF THE l PUBLIC.  !

5.1 Lan'd Use Census as Required by TS 3.12.2 .

1 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 jhe nearest milk animal, nearest residence and nearest steden larger

, than 500 tt producing broad leaf vegetation. The census shall be conducted by  ;

either a door-to-door survey, serial survey, or by consulting local agricultural <

l authorities (or a combination thereof). The data from the !.UC is used for updating the location / pathway for dose assessment and for updating the Radio- t logical Environmental Monitoring Program. l l

If the census identifies a location / pathway (s) yielding a higher potential dose- l' to a HEMBER 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 new location /pathvay(s) h' shall be used for dose assessment. Tables 3-2 and 3-3 shall be updated to I include the currently identified controlling location /pathvay(s). Also, if the ,

) census identifies a location (s) that yields a calculated petential dose (via the ,

same exposure pathvay) 20% greater than a location currently included in the Radiological Environmental Monitoring Program,'the new locations (s) shall be i added to the program within 30 days if samples are reasonably obtainable. The

, sampling locations (s) excluding control locations, having a lover calculated L dose via the same pathway may be deleted from the program at the time the nev -

) location /pathvay(s) is added. As required by TS 3.12.2 and 6.9.1.11, the nev C location / pathway shall be identified in the next Semiannual Radioactive Etfluent Release Report.

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

A. Data Compilation ,

A.1 Locations and pathways of exposura as identified by the land use census vill be compiled for comparison v'th the current locations as presented

i' B.1.1 Relative dose calculations should be based on a generic radionuclide '

distributisi (e.g., Davis-Besse USAR gaseous effluent source term of 9]

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

B.1.2 The pathway dose equations of the ODCM should be used. $

C. Data Evaluatinn  ;

c.1 The controlling location used in the ODCM Table 3-3 vill be verified.

If 0; location / pathway (s)'is identified with a higher rel'ative dose, $1 this location / pathway (s) should replace the previously identified controlling locatien/ pathway in Tabic 3-3. If the previously identified controlling pathway is no longer present, the current

> , controlling lnestion/pa hvay 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 l g-  !

EnvironmentalMonitoringProgram(ODCMSection6.0andTable6-1)shalll be reportec to NRC in accordance with TS 3.12.2, Action Item a. and b.'

and TS 6.9.1.11.

Radiological Effluent Technical Specification include the term e " which 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 and not an a posteriori (after the fact) limit for a particular measurement.

.Providing a decay correction for a'n evaluation of the capabilities of a system l

. does not appear appropriate. 'It may be appropriate to decay correct certain analyses of specific samples to determine radionuclide concentrations at the 0 ti,, oi ,,1,,,,, gy,, i, 131, ,,,,, ,,,3 , ,,,,,,, ion i,.no, ,,,,,,,1 ,, io, batch releases. Analyses are performed prior to any-releases and, the sample vill be decaying'at the same rate as the batch from which the sample was taken.

For continuous releases, decay correcting analyses of samples obtained over a O

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 .ived radionuclidos vi11 tend to reach an equilibrium value in the

~

sampling m dium as a function of source input and half-life. A single decay correction to adjust for sampling interval vill provide an unacceptable O: overestimate. squilibrium concentrations must de considered it analyses are to be indicative of actual release quantities.

Employing exp (-Mt) to adjust for radioactive decay between the end of sampling b and the time of analysis is straightforvati. However, to attempt te Jse the same term to adjust the decay during the samplin? period is not proper. As a practical matter, when the half-life of a radionuclide is long relative tr .e 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 O?

relatively unimportant.

At the other extreme, when the half-life of a radionuclide is much shorter than s

the sampling time or the time between the end of sampling and the analysis, the term exp(-Aet) could be used to adjust for decay between the end of sampling and g; the analysis. However, it would not be appropriate in that case to use the same j term to attempt to adjust' for decay during sampling. I i

The relationship betveen the radioactivity in a sample at the end of sampling g:

and activity concentration in the medium being sampled is somewhat more

.1 The NRC proposed equation appears to incorporate an adulterated vay of l encouraging analysis soon after the end of sampling and to encourage efficient sample concentration or radiochemical extraction. Although not rigorous, it 7 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. j I i A more n1arly 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 i being sampled can be calculated with the product of exp( 4 4t) for decay between the end of sampling and the analysis and one of the equations derived herein for 1 the relation between the medium being sampled and the activity in the sample at  !

I the end of sampling. i l t However, this method is not very practical or necessary considering the types of sampling and analysis at nuclear power plants, the significant radionuclides, i and the offsite potential doses. The bulk of radioactivity is released as batch j l releases with all sampling and,e.nalysis performed prior to release. Therefore,

)[ no decay corrections are applicable. It is in the sampling and analysis of continuous releases that the accumulation and decay of the radioactive material i 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

) qualities of short-lived radionuclides, while providing little improvement for Davis-Besse, Unit 1 J-11 Revision 3.1, 1989 D-9 k'

.Ch the quantification of the longer half-life radionuclides that are the major dose contributors. .

Overall, it'may be appropriate to decay correct a certain analysis to account IDl l

for radionuclide decay during the sampling pcriod. 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 u.1e of a decay IDi correction factor in.. defining a lower 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 ID correction for quantification of relesses.

e Milk samples from location T-20, 5.5 miles VSV of Davis-Besse, have become unavailable because the dairy fara has sold the herd. No replacement milk samplina locations are present within r.n eight kilometer (five mile) radius.

However, additicnal milk samples are being collected at a site arproximately six j miles SW of the site.

T-20 milk sampling location vili be deleted from the Offsite Dose Calculation Manual (ODCM) in the next revision.
