V. Major Maintenance Operations The primary coolant ion exchange resin was replaced once during the year, in March.

VI. Summary of 10 CFR 50.59 changes -

There were no 50.59 changes at the facility during this report period.

Vll. Radioactivity Releases A. Listed below is the total amounts cf radioactive gaseous effluent released to the environment beyond the effective control of the reactor facility.

• Note: The tritium concentrations are estimates based on the an.ount of water I lost by evaporation from the reactor multiplied by the concentration of tritium as  !

HTO. Tritium sample analyses are being performed by Barringer Labs.

B. Two 55-gallon drums of low-level radioactive solid waste were shipped for burial in Washington during the year.

Note: The principal radioactive waste generated at the reactor facility is the demineralized resin - used resin with small quantities of rinse water was de-watered by evaporation and placed in 55-gallon drums.
