- 4 INTRODUCTION This semi-annual report covers the period of January 1,
- 1999, through June 30,- 1992.
During this period, DAEC had a scheduled refueling outage that lasted 59 days, from February 27, 1992 to April 26, 1992.
There were no radioactive 11guld releases from DAEC during this reporting period.
Gaseous releases were continuous for the period and resulted in concentrations at the site boundary well below compliance levels for 10 CFR 50, Appendix I dose limits, and 10 CFR 20 concentration limits.
There were no abnormal releases of radioactive material to the environment.
A total of six solid radioactive waste shipments were made during the period.
Three shipments of spent resins and mechanical aqueous filters were sent directly for burial and three shipments of dry active waste were sent to a vendor for processing.
The shipment summary report, therefore, indicates both waste quantitles-shipped and the amounts buried.
There were no changes to the Offsite Dose Assessment Manual.
There were changes to the Process Control Plan.
A description of the change and a copy of the revised procedure are included as part of this report.
A summary.of meteorological data will be included in the Semi-Annual Eifluent Report for the second half of the calendar year per DAEC Technical Specifications.
.There were no Technical Specification Limiting Conditions for Operation or other occurrences that required special reporting to be included with this report.

SUMMARY
OF CHANGES T9 THE PROCESS CONTROL PLAN (PRCP)
During the period of January 1, 1992 through June 30, 1992, changes were made to pages 12, 24 and 26 of the Process Control Plan.
The changes allow for transfer of resins and sludges from temporary local installations in addition to the normal Radwaste Solids Handling System.
- The change was made due to cheiaical decontamination of recirculation piping that was performed during the refueling outage.
During this process, resin waste produced by temporary equipment was transferred into a high integrity container where it was dewatered and processed for shipment and burial.
