INTRODUCTION This nomi-annual report covers t.hu porlod of Docombor 26, 1990, t.hrough Juno 26, 1991. Thoso datos woro chosen so as to match as closoly as possibio tho ond of t.he calendar porlod with sampling performod under the DAEC SurveillanCo Tost.ing Program.

The datos, thoroforo, roilect. the sampling porlods for gaseous of tluonts and are limited by the quart.orly composite sampling datos for Stront. lum 09 and 90. The next Semi-Annual Hoport will begin with t.hu last dato from t.his report.

Thoro woro no radioactivo liquid roloanos from DAEC during t.his reporting period.

GaHoous roloanos woro cont.inuous for the porlod and resulted in concentrations at. the site boundary well below lovols nooded t.o comply with 10 CFR 50 Appondix 1 dono limit.e, and 10 CFR 20 concent. rat.lon limits . Thoro woro no abnormal releases of radioactivo matorial to the environmont..

A total of five solid radioact.lvo wasto shipments woro mado during the porlod. Thron shipment.s of spent rosins woro sont directly for burial and t.wo shipment.s of dry activu wast.o woro sont to a vendor for processing. The report thorofore indicatos both wast.o quant.ities shipped and the amount.s buried.

Thoro woro no changos to the of f a tto Dose Assosament. Manual.

The Process Control Plan was revisod to includo alternativo mot. hods for processing matorials into a high intogrity container or stool linor. A summary of the chango and the revised proceduro are included.
