TECIINICAL SPECIFICATION REPORTING REOUIREMENTS (Section 6.9.1.8) f i

A.

Previous Calendar Year (1992) Dose Assessment Summarv l

During 1992, liquid releases from Calvert Cliffs resulted in a calculated maximum j

annual organ dose of 0.40 mrem and a maximum whole body dose of 0.08 mrem.

[

These doses are less than 2.1% of the Technical SpeciGeation yearly organ dose limit and less than 1.3% of the Technical Specification yearly dose limit for the whole body. Rese doses were calculated using the methodology and parameters outlined in the ODCM. The controlling pathway was the fish and shellfish pathway with adult as the controlling age group, and the gastrointestinal tract representing the organ with the highest calculated dose.

j Gaseous releases of noble gases resulted in a maximum, quarterly, gamma-air dose of 0.04 mrad and a maximum, quarterly, beta-air dose of 0.11 mrad. lodines and j

particulates in gaseous effluents from Calvert Cliffs resulted in a maximum organ

{

dose of 0.48 mrem for the year via the child-infant-thyroid pathway. These doses were calculated using ODCM methodology. For 1992, calculated off-site doses via the gaseous' release pathways were bek)w 1.6% of their allowable Technical Specification limits.

B.

40 CFR 190 Total Dose Compliance 1

Based upon all releases for 1992 and the ODCM calculations, the maximum exposed l

individual would receive less than 2% of the allowable dose. During 1932, there were i

no on-site sources of direct radiation that would have contributed to a significant or i

measurable off-site dose. The direct radiation contribution is measured by both on-site and off-site thermoluminescent dosimeters (TLDs). The results of these measurements did not indicate any statistical increase in off-site radiation doses attributable to on-site sources. Therefore, no increase in the off-site calculated dose is attributable to the direct exposure from on-site sources. A more detailed l

evaluation will be reported in the Annual Radiological Emironmental Operating l

Report.

C.

Solid Waste Report Reauirements During the second half of 1992. the types of radioactive solid waste shipped from Calvert Cliffs were radioactive resin, which was dewatered and shipped in high integrity containers, low level radioactive resin which was dewatered and shipped in i

strong, tight containers, dry compressible waste, which was shipped as LSA waste in strong, tight containers, and irradiated waste which was shipped in a high-integrity l

steel container. Appendix A provides a detailed breakdown of the waste shipments for the second half of 1992 per the categories specified in Technical Specification 6.9.1.8.

ODCM and Process Control Procram (PCP) Chances One change was made to the ODCM during the second half of 1992. The change was reviewed by POSRC and approved by the Plant General Manager, Cahrrt Cliffs Nuclear Power Plant, prior to implementation. The scope and basis for this change is discussed in Appendix B.

In keeping with the requirement of the Technical 1

Specification 6.17, a copy of the approved change to the CCNPP ODCM is enclosed l

MEASUREMENTS AND APPROXIMATIONS AND TOTAL RADIOACTI\\TIY j

A.

Fission and Activation Gases 1

1.

Batch Releases Prior to each batch release of gas from a pressurized gas decay tank, a sample is collected and analyzed by gamma spectroscopy using a Germanium (Ge) i detector for the principal gamma emitting noble gas radionuclides. The total i

activity released is based on the pressure / volume relationship (gas laws) of the tank.

i f

Prior to and after each centainment purge, a gas sample is collected and j

analyzed by gamma spectroscopy using a Ge detector for the principal gamma cmitting noble gas radionuclides. The total activity released is based on j

containment volume and purge rate. Activity buildup while purging is also j

j considered.

i 2.

Continuous Releases I

i i

A gas sample is collected at least weekly from the main vents and analyzed by l

]

gamma spectroscopy using a Ge detector for the principal gamma emitting j

noble gas radionuclides. De total activity released for the week is based on -

1 the total sample activity decay corrected to the sample time, multiplied by the main vent flow for the week.

l I

A monthly composite sample is collected from the main vents and analyzed by liquid scintillation for tritium. The total tritium release for the month is based i

on this sample analysis and the vent flow.3 B.

Iodine and Particulates 1.

Batch Releases i

l The total actisities of radioiodines and particulates released from pressutized i

waste gas decay tanks, containment purges, and containment vents are accounted for by the continuous samplers on the main vent.

l 2.

Continuous Releases During the release of gas from the main vents, samples of iodines and l

particulates are collected using a charcoal and particulate filter, respectively.

The filters are removed weekly and are analyzed by gamma spectroscopy

{

using a Ge detector for significant gamma emitting radionuclides. The total j

activity released for the week is based on the total sample activity decay -

corrected to the midpoint of the sample period multiplied by the main vent -

l flow for the week. These weekly particulate filters are then composited to form monthly and quarterly composites for the gross alpha and strontium 89 and 90 analyses.

radionuclides. To demonstrate compliance with the requirements addressed j

in Section I.C.1 above, the measured radionuclide concentrations are compared with the allowable MPCs; dilution in the discharge conduit is considered, and an allowable release rate is verified.

b 1

Analysis results from the tritium sample for October 1992 erroneously indicated main vent tritium concentrations several orders of magnitude larger (i.e.,1E7 uCi/cc) than the concentrations normally experienced (i.e., IE10 uCi/cc).

This erroncous analysis result was thought to te hnked to a plant evolution where a pressure relief valve on the steam generator blowdown tank discharged secondary side steam to the plant vent stack. 'lhis steam saturated the tritsum sampler's sihca gel. It is postulated that at some point in time - cither before sample collection or after sample collecuoi:- the sample was contaminated.11 is hypothesir.ed that this contamination was the source of the erroneous analysis rea ult. 'Ihe plant data which supports this hypothesis is as follows. (1) The primary to secondary leak rate did not change significantly during the September / October timeframe, (2) the tritium concentration in the liquid radmaste i

processing s estem did not change significantly during the September / October timeframe, and (3) there were no indications < f commensurate increases in the concentrations of any other radionuchdes in the plant vent during the September /3ctober timeframe. In heu of reporting the erroneous analysis results,it was determined that the tntium concentratons from the previous or fo!!owing months (i.e., Septemter or November)- whichever was greater -- would i

be used to acmunt for the tritium actrvity released from the Unit 1 plant vent stack during October 1992. Since the September, Unit 1, plant vent stack tritium concentration (i.e.,6.41E-10 uCi/cc) was greater than the November, Unit 1 plant vent stack tritium concentration (3.32E-11 uCi/cc), the September value was chosen as the best estimate for the October, Unit 1 plant vent stack tritium concentration.

The total activity released in each batch is determined by multiplying the volume released by the concentration of each radionuclide. The actual volume released is based on the difference in tank. levels prior to and after the release. A proportional composite sample is also withdrawn for each release and this is used in turn to prepare monthly and quarterly composites for the gross alpha, strontium 89 and 90, and tritium analyses.

2.

Continuous Releases i

I Paior to discharge of any continuous releases, a sample is collected and analyzed by gamma spectroscopy for the principal gamma emitting radionuclides. The measured radionuclide concentrations are compared with the allowable MPC concentrations in the discharge conduit, and an allowable release rate is verified.

i When steam generator blowdown is discharged to the circulating water i

conduits, it is sampled daily and these samples are used in turn to prepare a i

weekly blowdown composite sample based on each day's blowdown. The weekly composite sample is analyzed by gamma spectroscopy for the principal gamma emitting radionuclides. These results are multiplied by the actual quantity of blowdown to determine the total activity released. The weekly composite is also used to prepare monthly and quarterly composites for tritium, gross alpha, and strontium 89 and 90 analyses.

During primary to secondary leakage, the secondary system becomes contaminated and subsequently, contaminates the turbine plant sumps. This low-level activity water (predominately tritium) is released directly to the Chesapeake Bay. This water is sampled at least weekly and composited.

These samples are added to a composite based on the amount released during that week. The composite sample is analyzed monthly for tritium and principal gamma emitting radionuclides. The results are multiplied by the actual quantity ofliquid released to determine the total activity released. This composite is used to prepare quarterly samples for strontium 89 and 90 i

analyses.

CilANGES TO TIIE CCNPP ODCM IN SECOND llALF 1992 j

SUMMARY

AND !! ASIS A major revision of the ODCM was approved on July 27,1992. The revision was controlled by the normal procedure change process. The change was reviewed by the Plant Operations and Safety

[

Resiew Committee (POSRC) and was approved by the Plant General Manager, Calvert Cliffs Nuclear Power Plant, prior to implementation. This process meets the requirements of CCNPP Technical Specification 6.17.

This revision of the ODCM represents a significant change in format; however, the methodologies outlined in the previous ODCM remain unchanged. The new formatting greatly improves the clarity j

and organization of the document. A copy of the revised ODCM is attached to this report.

This revision of the ODCM was resiewed in some detail during NRC Safety Inspection INSR 93-01.

The interested reader is referred to INSR 93-01 for additional information.
