Abstract
During 1968, the RA Reactor was operated at nominal power of 6.5 MW for 190 days, and during 50 days at lower power levels. Total production amounted to 31051 MWh which is 3.5% higher than planned. reactor was used for irradiation and experiments according to the demand of 600 users, of which 517 from the Institute and 83 externals users. This report contains detailed data about reactor power and experiments performed in 1968. It is concluded that the reactor operation was more successful than during previous years. There was only one longer interruption which lasted 27 hours because of the power cut on the cable for the pump station on Danube. Number of safety shutdowns were at the same level as during last year. The only significant incident in 1968 was air contamination with the radioactive argon in the reactor hall. The reactor operation was not interrupted although the hall was evacuated for two hours. The was no significant exposure of the staff. In April and September the integral dosed were higher than during other months because of the accident during refueling (mixing the slugs with irradiated and fresh fuel). There was no significant surface contamination, i.e. the decontaminated surface

Raktor nije prekidao rad iako je hala evakuisana u trajanju od dva sata. Vecih ozracivanja osoblja nije bilo. Aprila i septembra, integralna doza bila je veca nego u ostalim mesecima zbog akcidenta pri radu na izmeni goriva. Nije bilo znacajnijih kontaminacija povrsina pa su dekontaminirane povrsine izrazito male. U 1968, godini izradjen je uredjaj za mesanje goriva (stari i svezi gorivni elementi). Zahvaljujuci mesanju goriva postignuto je preko 50% bolje iskoriscenje goriva u odnosu na prethodni period. Prosecni zaposlenih broj ljudi bio je za 7 manji od preosecnog broja u prosloj godini. Plan rada za 1969. godinu bazira se na proizvodnji od 30 000 MWh a napravljen je na istim principima kao za prethodne tri godine.}
