MAINE YANKEE ATOMIC POWER COMPANY ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT January - December 1997

1.0 INTRODUCTION

Tables 1 and 2 summarize the quantity of radioactive gaseous 'and liquid effluents, respectively, for each quarter of 1997. Table 3 summarizes the solid waste shipped off-site for

. burial or disposal during 1997. Table 4 contains supplementary information.

Appendices A through D indicate the status of reportable items per the requirements of Off-site Dose Calculation Manual (ODCM) sections 2.1.5, 2.2.6, 2.3.3, 2.3.4, 2.5 and Appendix C.

There were no changes to the ODCM during 1997.

a. Fission and Activation Gases ,

Continuous Discharge - Vent stack samples are analyzed monthly. Activity levels detemiined are assumed constant for the surveillance interval. The continuous vent stack monitor reading is used as a basis for increasing periodic sample frequency.

Eatch Discharges - Direct measurements of the waste gas hold-up drums are taken prior to discharge. Containment vents and purges are analyzed by direct measurement of the containment atmosphere at periodic intervals during discharge.

b. Iodines Primary vent stack iodine totals are taken from a minimum of weekly measurements of an in-line charcoal filter.
c. Particulates Primary vent stack particulate totals are taken from a minimum of weekly measurements of an in-line particulate filter.
d. LiquidEffluents Samples of secondary systems liquid effluents are analyzed weekly for gross alpha, tritium, dissolved gases, and gamma emitting isotopes.

Each batch release is analyzed for gross alpha, tritium, dissolved gases, and gamma emitting isotopes prior to discharge.

Composite samples are made of secondary and primary system liquid effluents for a quarterly analysis of Strontium-90 and Strontium-89. Primary system liquid effluents are also analyzed quarterly for Iron-55.

L . operable in accordance with ODCM Sections 2.3.3 and 2.3.4. With less than the.

minimum number of channels operable and reasonable efforts lto retum' the i instrument (s) to operable status within 30 days being unsuccessful, ODCM

! Sections 2.3.3 and 2.3.4 requires an explanation for the delay in correcting the .

inoperability in the next Annual Effluent Release Report.

Response: The Service Water radiation monitor was out of service for the entire period of this

,. report. This condition resulted from three causes:

! . ' Lack of vacuum priming required to supply sample to the monitor. This was -

a result of the plant in shut down condition for the entire year, with the l vacuum priming system out of service.

. Inoperable sample pump due to mechanical failure.  ;

- Insufficient sensitivity of the existing monitor, with inadequate margin to l establish the required setpoint in the low dilution flow environment.

Vacuum priming has been restored and the sample pump has been replaced, i: restoring the monitor to operation. Because the instrument sensitivity issue is still unresolved, however, the unit has not been declared operable and the remedial

action remains in effect. A replacement radiation monitor with greater sensitivity, which will provide sufficient setpoint margin, has been purchased to resolve this
l. issue. Installation of the replacement monitor is anticipated by May 31,1998.

The Primary Vent Stack flow r::te meter remained inoperable for the entire penod of this report. Delay we.s experienced in scheduling a contract vendor, and performing the required traverse of the stack to verify the calibration of the unit.

The traverse was completed in December,1997, but the results did not meet the accuracy requirements, and were not accepted. A calibration by an alternate i methodology is scheduled for May,1998.
