.. INTRODUCTION This Semi-Annual Radicactive Material Release Report is for the period of July 1, 1993, through December 31, 1993.

There were no radioactive liquid effluent releases from the Duane Arnold Energy Center during this report period.

Gaseous effluent releases were continuous fcr the period and resulted in site boundary concentrations below 10 CFR 20 limits.

There were no abnormal releases of radioactive material to the environment.

A total of eleven (11) solid radioactive waste shipments were made during the period. Four shipments were spent resin and aqueous mechanical filters and four shipments were irradiated components, all sent directly.for burial at Barnwell, South Carolina. Three shipments were dry activated waste and were sent to Scientific Ecology Group (SEG) for processing at Oak Ridge, Tennessee. One shipment of contaminated liquids was sent to SEG i at Oak-Ridge, Tennessee for incineration.

There were no changes made to the Offsite Dose Assessment Manual or the Process Control Plan.

SUMMARY

OF CHANGES QE METEOROLOGICAL DATA The following pages are a summation of meteorological data accumulated during the calendar year 1993 by the MIDAS (Meteorological Information and Dose Assessment) System at the Duane Arnold Energy Center. Each table includes wind speed, wind direction, and stability class at the specified sensor height (33 feet or 156 feet). A summary table of all stability classes at each height is also included.

Data recovery for atmospheric stability, wind speed, and wind direction was 97% or greater at both 33 feet and 156 feet.
