SECTION 1 INTRODUCTION AND SUPPLEMENTAL INFORMATION

INTRODUCTION The Susquehanna Steam Electric Station (SSES) is located in Salem Township, Luzerne County, Pennsylvania. It is on the west bank of the Susquehanna River, 8 km northeast of Berwick. The Station consists of two boiling water reactor generating units, each with 1,050 MW net electrical capacity. The reactor and generating units were supplied by General Electric, while the Bechtel Corporation served as architect-engineer and constructor.

Construction of the Station began in the early 1970s. Fuel load began in Unit 1 in July of 1982. Initial criticality was achieved in the Unit 1 reactor on September 10, 1982. The reactor reached 100'lo power for the first time on February 4, 1983. Commercial operation of Unit 1 was declared on June 8, 1983.

Initial criticality of Unit 2 occurred on May 8, 1984. Unit 2 was declared commercial on February 12, 1985.

Airborne eNuents are released from the Susquehanna Station via five rooftop vents on the reactor building (see Figure 1). Each vent is continuously monitored, and a program of periodic sampling and analysis is conducted as specified in the plant Technical Specifications. All waterborne effluents are released in batch mode and are sampled and analyzed prior to release. Waterborne effluents from the site are released into the cooling tower blowdown line for dilution prior to release to the Susquehanna River (see Figure 2). Blowdown line flow rates are at least 5,000 gpm during periods of liquid radwaste release. The diluted effluent is introduced to the river by way of a perforated diffuser pipe placed on the river bed. The diffuser serves to rapidly and uniformly mix the station discharge with the main flow of the river.

This report presents a summary of the quantities of radioactive materials which were released from the Susquehanna Steam Electric Station during the period from January 1, 1996 to December 31, 1996. In addition, this report serves as a medium for notifying the US Nuclear Regulatory Commission staff of changes to PP&L's Offsite Dose Calculation Manual (ODCM) and Solid Waste Process Control Program (PCP) and documentation of any exceptions to the SSES effluent monitoring program which must be reported per Technical Specifications 3.3.7.10 and 3.3.7.11. A section containing corrections to a previously reported dose is also included.

Airborne and waterborne radioactive effluent releases to the environment during the report period were sampled and analyzed in accordance with the requirements of the Technical Specifications. All radioactive effluent releases were within the concentration and release limits specified in the Radiological ENuent Technical Specifications (RETS). Calculations and terms utilized in this report are those outlined in the SSES Offsite Dose Calculation Manual (ODCM).

Section 1 contains supplemental information pertaining to eNuents from the Susquehanna plant. Included are regulatory limits (Table 1), sampling and analysis methods, and characterization of the number and duration of batch and abnormal releases, if any.

Section 2 contains effluent and waste disposal data for the report period. Table 2 contains a summation of all airborne releases, grouped into the radionuclide categories of gases, particulates, iodines, and tritium. Average release rates are presented and compared to the applicable limits. Table 3 presents the activity totals of specific radionuclides in airborne effluents.

Waterborne effluents are summarized in Table 4. Average diluted concentrations are presented and compared to the applicable limits. Table 5 presents the release quantities of specific radionuclides in waterborne effluents over the report period.

Figure 3 lists the Susquehanna River monthly average flow rates for 1996 while Figure 4 presents the SSES monthly liquid radwaste discharge totals for 1996.

Tables 6 through 17 present a characterization of the solid radioactive waste shipped offsite during the report period (Tables 7 through 10 are reserved blank in this report). Included are the volumes and curie contents associated with each type of solid waste. An estimate of major nuclide composition is presented for each waste type, as well as the number of waste shipments from the site, how they were transported, and their final destination.

Table 18 contains estimates of the errors associated with the measurements involved in quantifying effluents. Sampling errors, counting errors, and errors associated with determining effluent flow rates and volumes all contribute to the total error of eNuent measurements. Error estimates are presented for each category of radionuclide detected in airborne and waterborne effluents and solid wastes during the report period.

Table 19 presents effluent data from previous report periods which was not available at preparation time for the associated annual report.

Section 3 of this report contains the meteorological data associated with the year 1996. Availability data for the SSES meteorological data are shown in Table 20.

Meteorological data for the calendar year is presented in the form of joint wind frequency distributions by atmospheric stability class. These distributions are presented in Table 21. Figures 5 and 6 are wind rose plots for the SSES primary meteorological 10-meter and 60-meter sensors, respectively. Figure 7 presents the relative prevalences of the Pasquill stability classes. In addition, the meteorological data from the report year were used to generate annual average relative concentrations (X/Qs) and deposition rates (D/Qs). These values are

presented in Table 22, and ar'e required input for use of the GASPAR code for calculation of the doses resulting from airborne releases.

Section 4 of this report contains an assessment of the calculated doses attributed to the reported radiological effluents for the calendar year. The LADTAP II code was used for calculation of doses from waterborne effluents. Table 23 contains site-specific parameters used for LADTAP II calculations for the Danville receiver.

The GASPAR code was used for calculation of doses from airborne effluents. The calculated doses and direct radiation estimates can be used to estimate the doses to maximally exposed members of the public. Table 24 summarizes maximum calculated doses and dose commitments to members of the public from airborne and waterborne effluents and direct radiation. Table 25 presents calculated collective doses to members of the public within the Riverlands/Information Center Complex. Table 26 summarizes the calculated doses for residences and other occupied areas within the SSES site boundary. Table 27 reports gamma and beta air doses from noble gas effluent for the same locations as Table 26.

Section 5 of this report is reserved for"documentation of changes to the Offsite Dose Calculation Manual and the Solid Waste Process Control Program. A copy'of changes to the ODCM during the report period is included in Appendix A. A copy of changes to the Solid Waste Process Control Program is included in Appendix B.

Section 6 presents a listing of cases (if any) in which airborne or waterborne effluent monitoring instrumentation was declared inoperable and was not restored to operability within the time period specified in Technical Specification Table 3.3.7.10-1 or 3.3.7.11-1 Action Statements.

Section 7 contains corrections to doses reported in previous Semi-annual or Annual Effluent and Waste Disposal reports.

Section 8 contains information on effluent (Table 28) and offsite dose (Table 29) from additional monitored release points.

SUPPLEMENTAL INFORMATION Re ulato Limits Technical Specifications 3/4.11.1 and 3/4.11.2 outline requirements for release of radioactive liquid and gaseous effluents, respectively. Concentration of radioactive materials released in liquid effluents and dose or dose commitment resultant thereof are limited in unrestricted areas. Dose and dose rate due to radioactive materials released in gaseous effluents are limited in areas at or beyond the site boundary. Technical Specification limits are listed in Table 1.

2. Maximum Permissible Concentrations in Waterborne Effluents The concentrations of radioactive materials in waterborne effluents are limited to the concentrations specified in 10 CFR Part 20 Appendix B Table II, Column 2, for radionuclides other than dissolved or entrained noble gases.

For dissolved or entrained noble gases, the concentrations are limited to the following values, as stated in the applicable Technical Specification:

Nuclide MPC uCi/ml 85mK 2.0E-04 85K 5.0E-04 87K 4.0E-05 88K 9.0E-05

"'AI 7.0E-05 133mXe 5.0E-04 133xe 6.0E-04 135mXe 2.0E-04 135X 2.0E-04 3; Avera e Ener Based on gaseous effluent releases for the report period average beta energy is 0.322 MeV and average gamma energy is 0.246 MeV.

4. Measurements and A roximations of Total Radioactivit Analyses of specific radionuclides in effluent samples are used to evaluate the radioactive composition and concentration of effluents.

5. Methods of uantif in Effluents Fission and Activation Gases: Gas samples are routinely collected monthly and analyzed with a high resolution (Ge[Li] or HPGE) detector system which incorporates a data reduction program to determine radionuclide composition in terms of specific activity. Data tapes from the continuous vent monitors are used to determine the average concentration of noble gases. The high resolution (Ge[Li] or HPGE) isotopic scan is used to convert the continuous vent monitor activity to actual activity based on the determined nuclide mixture. The vent and sample flow rates are continuously monitored and the average flow rates for each vent are used to calculate the total activity released in a given time period. When the continuous monitors are out of service, manual grab samples are taken from each vent once each eight hours (once each four hours for the standby gas treatment vent).

lodines: iodine is continuously collected via an isokinetic sampling assembly in each vent. Filters are normally exchanged once per week and analyzed on a high resolution (Ge[Li] or HPGE) system. The daily average flow rates for the vents and sample pumps are averaged for the duration of the sampling period and a ratio of vent flow rate to sample flow rate is determined. The ratio is used to determine the total activity of each isotope released during the time period in question. When the continuous monitors are out of service, iodine is continuously collected on charcoal cartridges attached to air samplers which draw directly from the affected rooftop vent(s) or from alternate sampling ports available on the sample lines.

Particulates: Particulates are continuously collected via an isokinetic sampling assembly in each vent. Filters are normally exchanged once per week and analyzed on a high resolution (Ge[Li] or HPGE) system. Flow rate corrections are performed as for iodines. When the continuous vent monitors are out of service, particulates are continuously sampled directly from the affected rooftop vent(s) or from alternate sampling ports available on the sample lines.

Tritium Airborne tritium is collected monthly via bubbler sampler. The sample is collected for one hour at a flow rate of approximately 1000 cc/min.

Tritium activity in the bubbler sample is determined by liquid scintillation counting. The liquid sample tritium concentration is converted to air concentration by volume proportion, then compared to the Technical Specification Table 4.11.2.1.2-1 Lower Limit of Detection (1 E-6 uCi/cc).

e. Waterborne fffluents: Each tank of liquid radwaste is sampled and analyzed for principal gamma emitters prior to release. Each sample tank is recirculated for a sufficient amount of time prior to sampling to ensure that a representative sample is obtained. Samples are analyzed on a high resolution (Ge[Li] or HPGE) system and release permits are generated based on the values obtained from the isotopic analysis and the most recent values for tritium, gross alpha, iron-55, and strontium-89 and -90. An aliquot based on release volume is saved and added to monthly and quarterly composite containers. The monthly tritium analysis is done in-house. The monthly liquid radwaste composite sample is also analyzed offsite for P-32. The quarterly composite is sent to a vendor laboratory for iron-55, strontium-89 and -90, and gross alpha analyses.

The concentration of each radionuclide in each batch is decay corrected from the time of counting to the midpoint of the release period, and is then multiplied by the volume of the batch to determine the total quantity of each nuclide released in each batch. The isotopic totals for each are summed to determine the total source term for the report period.

E..WATERBORNE EFFLUENT: BASES FOR PERCENT OF APPLICABLE TECHNICAL SPECIFICATION LIMIT Fission and Activation Products

. Concentrations of fission and activation products in liquid effluent from radwaste effluent are determined for each batch prior to release. Each isotope concentration is compared to 10CFR20 Appendix 8, Table II, Column 2 Maximum Permissible Concentration Limits such that, with clillution,'he sum of isotope concentrations divided by Maximum Permissible Concentrations must be <1.0. No Technical Specification limit for the total concentration of fission and activation products in liquid effluents is applicable for this category.

Tritium Liquid effluent quarterly tritium concentrations are compared to the 10 CFR 20 Appendix B, Table II, Column 2, Maximum Permissible Concentration limit of 3.0E-03 uCi/ml to unrestricted areas.

Dissolved and Entrained Gases Liquid effluent quarterly concentration totals for dissolved and entrained gases are compared to the most restrictive Maximum Permissible Concentration for a noble gas 4.0E-05 uCi/ml (Kr-87) from the SSES Technical Specification Table 3.11.1.1-1.

SECTION 3 METEOROLOGICAL DATA AND DISPERSION ESTIMATES 38

METEOROLOGY AND DISPERSION DATA Meteorological data have been collected at the Susquehanna SES site since the early 1970s. At the present time, the meteorological system is based on a 300-foot high tower located approximately 1,000 feet to the southeast of the plant. Wind sensors are mounted at the 10-meter and 60-meter elevations on this tower.

Vertical temperature differential is measured with redundant sensor pairs between the 10m and 60m levels. Sigma theta (the standard deviation of horizontal wind direction) is calculated from wind direction at both levels. Dew point and ambient temperature sensors are present at the 10m level. Precipitation is measured at ground level.

A back-up meteorological tower was erected in 1982. It is a 10-meter tower providing alternate measurements of wind speed, wind direction, and sigma theta.

SSES meteorological data is transmitted to the plant control room, Technical Support Center, and Emergency Operations Facility for emergency response availability. The data is also transmitted via telephone line data-link to the PP8L corporate computer in Allentown.

Dispersion modeling for effluents from normal operation of SSES is done using XOQDOQ, a straight-line air flow Gaussian plume model designed to estimate average relative concentrations. The model was developed in accordance with Regulatory Guide 1.111. Calm periods are distributed as the first non-zero wind-speed class in the input joint frequency distribution file.

XOQDOQ uses terrain correction factors to account for the temporal and spatial variations in the airflow in the region, since a straight-line trajectory model assumes that a constant mean wind transports and diffuses effluents in the direction of air flow at the release point within the entire region of interest. The SSES terrain correction factors were determined by the ratio of the results of the straight-line model to the puff-advection model, and are incorporated into Table 22.

SECTION 4 DOSE MEASUREMENTS AND ASSESSMENTS 68

Radiolo ical Im act on Man Sampling and analysis of airborne and waterborne effluents were performed in accordance with the frequencies, types of analysis, and Lower Limit of Detection (LLD) outlined in the SSES Technical Specifications.

Radioactive material was detected in some of the airborne and waterborne effluent samples analyzed. Dose calculations using measured effluent activity levels, meteorological data from the current reporting period and average river flow dilution factors resulted in estimated doses to individuals at levels below 10 CFR 20 and 10 CFR 50, Appendix I limits. Direct radiation resulting from plant operation, as measured by environmental thermoluminescent dosimeters located around the plant contributed a maximum of 3.41E-03 mrem (measured at TLD Location 11S3) at the Protected Area Boundary southwest of the plant. This measurement includes the immersion dose from noble gases. The maximum organ/total body dose (Table 26) from all airborne effluent is 1.86E-01 mrem. The maximum organ/total body dose from liquid effluent (child bone: Table 24) is 3.78E-01 mrem. If it is conservatively assumed that a member of the public receives the maximum total body/organ dose from liquid and gaseous combined with the maximum total body dose determined from direct radiation, the result (5.64E-01 mrem) is 2.3% of the 40CFR190 limit of 25 mrem to total body/organ (except thyroid).

Doses to a maximally exposed member of the public from waterborne effluents are calculated for fish ingestion and shoreline exposure at the plant outfall, and drinking water ingestion at Danville, PA. Site specific parameters used in the calculations for the Danville receiver, specific for actual average blowdown and river level in each quarter and the entire year, are shown in Table 23.

Summaries of maximum individual doses resulting from airborne and waterborne radioactive effluent releases are given in Table 24. Meteorological data from Section 3 were used to calculate the dose from airborne effluents.

Technical Specification 6.9.1.11 requires assessment of radiation doses from radioactive airborne and waterborne effluent to members of the public within the site boundary. There are no significant exposure pathways from waterborne effluents in these areas. Onsite doses are assessed relative to offsite dose values and are adjusted for appropriate dispersion and occupancy factors. Summaries of the calculated maximum doses within the site boundary and selected locations resulting from airborne effluents are presented in Tables 25 through 27.

DOSES TO MEMBERS OF THE PUBLIC WITHIN THE SITE BOUNDARY SSES Technical Specification 6.9.1.11.requires that the Annual Effluent Release Reports include an assessment of the radiation'dose from radioactive effluents to members of the public within the site boundary. Within the SSES Site Boundary there are several areas frequented by members of the public. The SSES Riverlands Energy Information Center is a representative nearby location visited by members of the public. Doses from airboine effluent are calculated for members of the public for this location. The Riverlands, selected residences within the Site Boundary, and the maximum site boundary location for which dose calculations are performed are shown in Figure 8.

In the area comprising the Riverlands recreation area, which surrounds the Energy Information Center, three pathways of radiation exposure can be identified; plume, ground and inhalation. There are no significant exposure pathways from waterborne effluents in this area. There are approximately 100,000 visitors to the Riverlands/Information Center complex each year. For dose calculations, the visitor stays in the area for one hour.

Use of the GASPAR code yields calculated doses for the Riverlands area for the report period. These doses are the total doses at the location from gaseous effluents during the report period. In order to compute doses to members of the public who stay for only short periods of time, these doses are converted to dose rates which are averages for the entire year. Taking into account the estimated 100,000 person-hours of occupancy, the collective (person-rem) doses shown in Table 25 are calculated.

Table 27 contains beta and gamma air doses from noble gas effluent at the same locations as Table 26, with resulting percent Tech. Spec. limits.

SECTION 5 CHANGES TO THE OFFSITE DOSE CALCULATIONMANUAL AND THE SOLID WASTE PROCESS CONTROL PROGRAM 77

. CHANGES TO THE OFFSITE DOSE CALCULATIONMANUAL The SSES ODCM was revised once in 1996. The change in 1996 is designated Revision 6 by the SSES Document Control Center.

In Revision 6, Maximum Dose Factors have been added in Table 4 for Ru-103 and Te-129, in response to CR 95-0743.

Water sampling location 2S7 was added to Table 6 and Figure 5. This location was" created to obtain more representative samples for the REMP program.

Air sampling locations 6G1 and 8G1 were added to Table 6 and Figure 6; locations 12G1 and 7G1 were deleted from Table 6 and Figure 6. Location 12G1 was moved to location 6G1 to improve control characteristics at this location. The air sampling station was moved to location 8G1 to avoid large trees which hindered sampling at 7G1.

A sentence was added to Section A.1.2.1 to restore the context of this paragraph; this change was made in response to Audit 95-114, Observation 7.

This revision did not reduce the accuracy or reliability of dose calculations or setpoint determinations utilizing the methodology and parameters previously approved for the ODCM.

A copy of Revision 6 of the SSES ODCM is included under separate cover in Appendix A.

78

CHANGES TO THE SOLID WASTE PROCESS CONTROL PROGRAM NDAP-QA-0646 did not undergo revision during the report period (1996).

PCAFs 1-95-0007 and 1-97-0017 have been incorporated into NDAP-QA-0646, however, not during the report period. These PCAFs do not reduce the overall conformance of the solidified waste program to existing criteria. A copy of SSES Radioactive Waste Process Control Program, NDAP-QA-0646, Revision 4, is included under separate cover as Appendix B.

79

SECTION 6 REPORTS OF EXCEPTION TO THE SSES EFFLUENT MONITORING PROGRAM 80

REPORTS OF EXCEPTION TO THE SSES EFFLUENT MONITORING PROGRAM One event occurred during the reporting period which is reportable under Technical Specification 3.3.7.11 Action b, with specific reference to Table 3.3.7.11 -1 Action 112.

On August 2, 1996, at 1135, SSES Chemistry was notified by Operations that 'A'SS BUS had tripped at 1105. As a result of this trip, Zone 1 and Zone 3 ventilation was lost and vent stack SPINGs were alarming. At that time, it was assumed that the alarm condition was normal for the loss of ventilation condition, however, at 1300 a second Chemistry technician noticed that alarms had not cleared even though ventilation had been restored. Technicians then accessed the SPING monitors on el. 818 and confirmed that sample pumps on UI Tb and Ul Rb vent were not functioning.

Continuous sampling was re-established on Ul Tb at 1350 and Ul Rb at 1400.

Particulate, iodine and noble gas samples was taken for both vents in accordance with Chemistry procedures, and no activity was detected.

This event is reportable because continuous ventilation sampling for particulate, iodine and noble gas was not performed for approximately 2-1/2 hours when the'A'SS BUS was lost. Technical Specification 3.3.7.11 Action 112 requires continuous sampling with auxiliary sampling equipment when less than the required number of operable channels are in service. CR 96-1073 and LER 387/96-008 have been generated for this event.

SECTION 8 EFFLUENT FROM ADDITIONALMONITORED RELEASE POINTS 84

EFFLUENT FROM ADDITIONALMONITORED RELEASE POINTS The Dry Active Waste (DAW) facility is a processing system located in a trailer near the administration building. Since the facility is used to reduce DAW volume, the trailer atmosphere is sampled routinely for airborne activity. The effluent potential for this system was determined in Safety Evaluation NL-89-002. It has been classified as an Insignificant Effluent Pathway in the ODCM. In 1996, several air samples taken from the trailer were noted to have Mn-54 and Co-60 above the minimum detectable activity. The following airborne particulate effluent and resulting offsite dose to members of the public at the residence 1.1 miles WSW is reported for the DAW facility. This effluent and resulting offsite dose is reported supplementary to Tables 3, 4, 24 and 26 since it is minor relative to the quantities reported therein (i.e. not observable at three significant figures):
