!I INTRODUCTION Radiological Environmental Monitorine Procram (REMP)- 1996 The following submittal is for the Fort Calhoun Station (FCS) Annual Radiological Environmental Operating Report-1996, representing the perfomtance ofthe Radiological Enviromnental Monitoring i

Program (FWMP). Results of completed sample analyses as required by the FCS Offsite Dose Calculation Manual (ODCM) are presented in the attached tables. Collection of environmental sample media was performed by the Licensee (Omaha Public Power District) and sample analysis jl was performed by contract vendor (Teledyne Brown Engineering--Northbrook, Illinois). Data obtained for the IGMP this reporting period were well within expected ranges and compared favorably to historical trends. None of the media sampled contained radioactivity attributable to the

! operation of the Fort Calhoun Station. The following observations and anomalies were documented during the monitoring period:

1) EtticI - Tritium was detected in the first and second quarter composite samples collected 0.5 miles downstream of the Plant at an analytical LLD of 300 pCi/L (767 109 pCi/L, iE 305

• 91 pCi/L, respectively). The 40 CFR 141 and ODCM limit for tritium in drinking

E water is 20,000 pCi/L. Plant staff reviewed effluent release data for this period and found

, no abnormalities. Evaluation of tritium analyses data from the nearest downstream mumcipal drinking water intake (Metropolitan Utilities District-Omaha, Nebraska) indicated no detectable levels.

2) Dmimtity - All field dosimetry was collected within the required frequency, however, the 25% allowance for surveillance completion was exercised. In order to return sampling to the

normal schedule, increased sampling was performed resulting in a greater number of dosimeters being analyzed than the minimum required by the ODCM. Deviations due to mitigating circurnstances are allowed by the ODCM for the RI .MP. The effectiveness of the REMP was not reduced as a result.

F I

3) Eish - Several fish species of both commercial and recreational interest were collected and analyzed during this reporting period. The unavailability of certain species during the

g monitoring effort resulted in two substitutions in accordance with the proceduce. If a desired E species cannot be located or if a sufficient numbe of specimens of a desired species cannot be collected, then a species or combination thereof, in a similar feeding class will be included

and/or substituted. FCS is concerned about both protected / endangered species and

unprotected species in the Missouri River and every effort is taken to reduce the amount of

, fish collected of unprotected species and to avoid the known habitat of protected species so they are not disturbed. The fellowing substitutions were perfonned due to mitigating circumstances allowed by the ODCM:

a. For the control location (Missouri River Mile 645.0, Upstream of Plant), two species

were composited because sufficient numbers of specimens fmm the desired species

could not be collected by weight that would yield enough flesh for a representative analysis. The two species combined were Small mouth Buffalo (Ictiobus bubalus) and Goldeye (Hiodon alosoides),

b. For the contro! location, Carp (Cyprinus carpio) was substituted for Gizzard Shad (Dorosoma cepedianum) because suflicient numbers of Shad could not be collected by weight required for a representative analysis.

4. Air - Only one air sampling unit was inoperable during the reporting period for a total downtime of three weeks. One other anomaly was recorded, not relative to a dmyntime event. Observations were as follows:

j a. Onsite Station Unit No. 02, OAP-B-(l),0.6 miles SW of Reactor, was shutdown from 03-27-96 through 04-17-96 due to two failures. Unit malfunctions included "as found" problems with a timer and a flowrneter.

E b. On 12-18-96, a sample filter from Onsite Station Unit No. 03, OAP-C-(I),0.8 miles SE of reactor, was inadvertently lost by the technician when blustery wind conditions I blew the filter out of his hand. The iodine cartridge was collected and analyzed. The concentration for this sample yielded < LLD (0.07 pCi/m 3).

There were no abnonnal observations noted with bottom sediment, food product, and milk sample collection. Sampling was conducted as scheduled.

NOTE: Teledyne's Midwest Laboratory participates in intercomparison studies adaunistered by U.S. EPA Environmental Monitoring Systems laboratory, Las Vegas, Nevada. The results are reported in Appendix A. Also reported are results of International Intercomparison and Teledyne testing of I T1.D's, as well as, in-house spikes, blanks, duplicates and mixed analyte performance evaluation program. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only. Please refer to March, June, September and December progress reports for information.

January,1996 through December,1996 I

I AnredEx A I Interlahnratory Cnmnarknn Pmeram Resuk

\

Teledyne's Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in ,

interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in l I December 1971. Rese programs are operated by agencies which supply environmental type samples (e.g.,

milk or water) contaming concentrations of radionuciides know to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on the laboratory's l

1 I analytical procedures and to alert it to any possible problems.

I Participant laboratories measure the concemration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the cone.ol limits indicate a need to check the instruments or procedures used.

1 The results in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months Data for previous years is J

I available upon request.

This progmm is conducted by the U.S. Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support laboratory, Las Vegas, Nevada.

j The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), since 1976 via 3 various International Intercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2. Also Teledyne testing results are listed.

Table A-3 lists results of the analyses on in-house " spiked" samples for the past twelve months.  !

All sareples are prepared using NIST tracable sources. Data for previous years available upon  !

4 request.

4 Table A-4 lists results of the analyses on in-house " blank" samples for the past twelve months.  !

Data for previous years available upon request. l Table A 5 list results of the in-house " duplicate" program for the past twelve months. Acceptance is based on the difference of the results being less than the sum of the errors. Data for previous years available upon request.

I The results in Table A-6 were obtained through participation in the mixed analyte performance evaluation program.

The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.

Attachment A lists acceptance criteria for " spiked" samples.

Out-of-limit results are explained directly below the result.

Data Reporting Conventions I

1.0 All activities except gross alpha and gross beta are decay corrected to collection time or the end of the collection period, 2.0 Si.6as.uremcnis Each single measurement is n:poned as (gliows:

i.

< I where x = value of the measurement; xis s=2a counting uncertainty (corresponding to the 95% confidence level).

In cases where the activity is found to be below the lower limit of deteedon L i

it is reported as

<L

where L = the lower limit of detection based on 4.66c uncertainty for a background sample.

3.0 RupJicate attalyssa I 3.1 bdividual.tclulk*i xlist xits2 Reported result; xis where x = (1/2)(x1i x2)

I 4.0. Comnutation of hagn and Standard Deviaties 4.1 Averages and standard deviaticas listed in the tables are computed from all of the individual measurements over the period averaged; for ext.Inple, an annud standard I deviation would not be the average of quarterly standard deviations. The average x and t,tandard deviation (s) of a set of n numbers x1, x2. . . xn are defined as (chows:

fr(x-x,)'

sa n-1 4.2 Values be!ow the highest lower limit of detection are not included in the average.

4.3 If all of the values in the averaging g:0up are less than the highest !.LD, the highest

.I 4.4 LLD is reported.

If au but one of the values are less than the highest LLD, the single value x and associata! two sigma error is repor'ed. .

4.5 In rounding off the fonowing rules are foDowed:

I 4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanged. As an example,11.443 is rounded off to 11.44.

4.5.2. If the figure following those to be retained is greater than or equal to 5, the i figure is dropped and the last retained figure is raised by 1. As an example, 11.446 is rounded off to 11.45.

I Technical Soecification 2.1.3 Reauirements In accordance with Technical Specification 2.1.3, the following infonnation is presented for times I during the reporting period when Reactor Coolant DEI (Dose Equivalent ledine) was greater tlwn 1.0 pCi/g:

l

1. Reactor Power history starting 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> prior to first sample in which the limit was exceeded.

2. Purification System Flow history starting 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> prior to the first samp!e in which the limit was exceeded.

3. The time duration when the radioactivity of the reactor coolant exceeded 1.0 Ci/g Dese i Equivalent Iodine.

I

4. Results of the last isotopic analysis fer radioiodine performed prior to exceeding the limit, results of analysis while the limit was exceeded, and results of one analysis after the radiciodine activity was reduced to less than the limit. Each result should include the date  ;

and time of sampling and the radiciodine concentrations.

5. A graph ofI-131 concentration and one other radiciodine isotopic concentration in pCi/g as  !

a function of time for the duration of the specific activity above the steady state limit. l Dose Equivalent lodine exceeded 1.0 Ci/g three times during the reporting period. The first was j in March 1996, following a short duration shutdown, Duration of time above the limit was

, approximately 39 hours4.513889e-4 days <br />0.0108 hours <br />6.448413e-5 weeks <br />1.48395e-5 months <br /> and 58 minutes. The second was in June 1997, also following a short

, duration shutdown. Duration of time above the limit was approximately 33 hours3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> and 35 minutes.

The last time Dose Equivalent Iodine exceeded the limit was in October 1996, following shutdown for our refueling outabe. Duration of time above the limit was approximately 38 hours4.398148e-4 days <br />0.0106 hours <br />6.283069e-5 weeks <br />1.4459e-5 months <br /> and 51 minutes.

1 In all three cases the limit was exceeded due to shutdowns with fuel integrity problems.
