SUMMARY

BOSTON EDISON COMPANY Pilgrim Nuclear Power Station Radioactive Effluent and Waste Disposal Report including Meteorological Data January 1 to June 30,1995 INTRODUCTION This report quantifies the radioactive gaseous, liquid, and radwaste releases, and summarizes the local meteorological data for the period from January 1 to June 30, 1995. This document has been prepared in accordance with the requirements set forth in the Pilgrim Nuclear Power Station (PNPS) Technical Specifications and Revision 1 of Regulatory Guide 1.21, " Measuring, Evaluating, and Re aorting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquic and Gaseous Effluents from Light Water Cooled Nuclear Power Plants."

The quantity of radioactive material released from Pilgrim Station was determined from i

sample analyses of gaseous releases from the main stack, reactor building vent, and turbine building, and liquid releases into the discharge canal. The quantity and volume of radioactive waste which was shipped off-site from Pilgrim Station for burial was determined from data contained on the radwaste shipping documentation. The meteorological data were obtained from instrumentation measurements from the 220 foot meteorological tower located at Pilgrim Station.

GASEOUS EFFLUENTS The gaseous radioactive releases for the reporting period are quantified in Tables 1 A, 1B and 1C. Radioactive noble gases released during the period totalled 1743 curies.

Releases of radioactive particulates and iodines from the main stack, reactor building vent, and turbins building, totalled 0.005 curies, and tritium releases totalled 16.3 curies. No gross alpha radioactivity was detected in gaseous effluents.

LIQUID EFFLUENTS The liquid radioactive releases for the reporting period are quantified in Tables 2A and

28. Liquid effluents into the discharge canal resulted in a total release to the environment (Cape Cod Bay) of 0,069 curies of fission and activation products and 7.71 curies of tritium. Dissolved and entrained gases were not detected. No gross alpha radioactivity was detected.

SOLID WASTE Boston Edison's radioactive waste burial allocation in Barnwell, South Carolina was suspended in early 1994. Although some shipments of radioactive waste materials were made off-site for volume reduction and/or salvage, no disposal of radioactive waste took place during the reporting period. Any radioactive residue arising from the processing of the waste will be returned to Boston Edison for interim storage at Pilgrim Station.

METEOROLOGICAL DATA l

The meteorological data joint frequency distributions are listed in Tables 4A-1 and

(

4A-2. The percent data recovery for the reporting period was 96% on the 33 foot and 97% on the 220 foot elevations of the 220 foot meteorological tower at Pilgrim Station.

The predominant wind direction was from the south-southwest, which occurred approximately 13% of the time during this period. The predominant wind speed range at the 220 foot sensor was 13 to 18 mph, which occurred 31% of the time during this period. The predominant wind speed range at the 33 foot sensor was 4 to 7 mph, which occurred approximately 45% of the time. The predominant stability class was stability class D, which occurred about 36% of the time during this period.

CONCLUSION The PNPS Technical Specifications contain limiting conditions for operations and i

operational objectives regarding radiological environmental releases. None of the limiting conditions for operation or operational objectives associated with liquid or gaseous effluents were exceeded during this reporting period, as confirmed by conservative dose assessments performed on a monthly basis during this penod.

Official dose assessments will be published in a supplement to this report due 90 days following January 1,1996. Conformance to these PNPS Technical Specification operational objectives ensures that the releases of radioactive materials in gaseous and liquid effluents were kept as low as is reasonably achievable in accordance with the Nuclear Regulatory Commission's regulation 10CFR50, Appendix 1. Furthermore, compliance with PNPS Technical Specifications demonstrates compliance with the Environmental Protection Agency's (EPA) federal environmental regulation 40CFR190.10, Subpart B.

INTRODUCTION This report is issued for the period January 1 to June 30,1995 in accordance with the Boston Edison Company's PNPS Technical Specifications and NRC Regulatory Guide 1.21, " Measuring, Evaluating and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous l

Effluents from Light Water Cooled Nuclear Power Plants," Revision 1 (Reference 1).

Regulatory Guide 1.21 requires an assessment of the radiological impact on man resulting from radioactivity released in liquid and gaseous effluents. This assessment is to be performed using effluent and meteorological data collected during the semiannual period covered by the report. Due to the complexity of calculations involved with performing such an assessment, it was impractical to complete the assessment within the 60 day issuance requirement for the report.

Therefore, PNPS Technical Specifications were modified in May 1988 (Amendment #116) to allow for submission of a supplemental report containing 1

the radiological impact assessments. This report is to be issued by April 1, and is to contain impact assessments for both semiannual periods (January-June, July-December) for the previous year. Since Technical Specification limits for gaseous effluents listed in Table 1 A are based on calculated dose, these values l

are not presented in the semiannual effluent release report. These " percent of technical specification limit" values will be presented in the supplemental report issued prior to April 1.1996.

RADIOACTIVE EFFLUENT DATA Radioactive liquid and gaseous releases (Reference 2) for the period January 1 to June 30,1995 are given in the standard NRC Regulatory Guide 1.21 format in Tables 1 A,18,1C,2A,2B, and the supplemental information form.

2.1 Gaseous Effluents Gaseous radioactivity is released from Pilgrim Station to the atmosphere from the main stack and the reactor building exhaust vent. These gaseous effluent releases for the reporting period are summarized in Table 1 A. Noble gases released during the period totalled 1743 curies, for an average release rate of 111 pCi/sec. A total of 0.005 curies of radioactive iodines and particulates with half-lives greater than 8 days was released at an average release rate of 0.00032 pCi/sec. No alpha radioactivity was detected on particulate filters during this reporting period. A total of 16.3 curies of tritium was released at an average release rate of 1.03 pCi/sec.

The main stack is an elevated release point with a height of approximately 400 feet above mean sea level. The main stack is located about 700 feet west-northwest of the reactor building. The elevated releases for the reporting period are shown in Table 18.

The majority of ground-level releases during the period occurred from the reactor building vent, but low levels of radionuclides were also detected in air exhausted from the turbine building. The reactor building exhaust vent is considered a mixed-mode / ground-level release point with a height of approximately 182 feet above mean sea level. The exhaust vent is located on the west corner of the reactor building. Combined ground level releases from both the reactor building vent and turbine building for the reporting period are shown in Table 1C.

2.2 Liauid Effluents Liquid radioactivity is released from Pilgrim Station to the Cape Cod Bay

[

via the circulating water discharge canal. These effluent releases enter the Cape Cod Bay at the outfall of the canal which is located about 1100 j

feet north from the reactor building.

The liquid releases for the reporting period are summarized in Table 2A.

A total of approximately 1.6 million liters of radioactive liquid waste (prior to dilution) containing 0.069 curies of fission and activation products (excluding tritium, gases, and alpha-emitting nuclides) was discharged with a total dilution volume of approximately 5.2 billion liters of water. The liquid effluents were released at an average concentration of fission and activation products of 1.35E-08 pCi/ml. A total of 7.71 curies of tritium was released, resulting in an average concentration of 1.50E-06 pCi/ml.

No dissolved and entrained gases were detected in liquid effluents during the period. Alpha radioactivity was not detected during this reporting 3eriod. Quarterly release estimates and principal radionuclides in the i

iquid effluents are given in Table 28.

RADIOACTIVE WASTE DISPOSAL DATA l

In early 1994, Boston Edison's radioactive waste burial allocation with Chem Nuclear Systems, Inc. in Barnwell, South Carolina was suspended. Since Massachusetts is not a member of Southeast Compact, it is no longer allowed to bury its radioactive wastes at facilities within the compact. Until a disposal location is agreed u ]on, PNPS's radioactive wastes will be held in en interim storage facility at Pi grim Station.

Some shipments of radioactive wastes were made off-site during the reporting period for purposes of volume reduction and/or salvage. However, none of the j

radioactivity was disposed of via burial. Any radioactive residue recovered from the processing of the wastes is to be returned to Pilgrim Station for interim storage.

MET,EOROLOGICAL DATA Meteorological data (Reference 3) for the period January 1 to June 30,1995 is given in Tables 4A-1 and 4A-2 in the standard joint frequency distribution format

- as given in NRC Regulatory Guide 1.21.

The predominant wind direction was from the south-southwest, which occurred about 13% of the time during this period. The predominant wind speed range at the 220 foot sensor was 13 to 18 mph, which occurred with a frequency of 31%

during this period. The predominant wind speed range at the 33 foot sensor was -

4 to 7 mph, which occurred approximately 45% of the time. The predominant stability class was stability class D, which occurred about 36% of the time during this period.

There were instances where the data recorded by the 220 foot tower were not continuous. Typically, data losses were due to loss of power, malfunction of the sensors, and/or malfunction of the digital dataloggers. On May 16,1995, the elevator system for meteorological sensors on the 220 foot tower failed when the transport cable broke. Meteorological data collected from both levels of the tower was inoperable until June 26, when the system was repaired and returned to operation. Due to the extensive loss of data during this period, meteorological data from the backup 160 foot tower were scaled to 220 foot values, and were subsequently substituted for the missing data. Without the replacement information, data recovery for the second quarter would have been 52%. When the replacement data was incorporated, the net result is that the data recovery for the period was 96% on the 33 foot elevation and 97% on the 220 foot elevation of the meteorological tower at Pilgrim Station.
