Abstract

Highly enriched (80%) uranium oxide fuel was regularly used in the mixed reactor core with the 2% enriched fuel since 1976. The most important changes related to reactor operation, in comparison with the original design project were related to reactor core fuelling schemes. At the end of 1979 reactor was shutdown due to the corrosion coating noticed on some fuel elements and due to decrease quality of the heavy water. Subsequently the Sanitary inspector of Serbia has prohibited further reactor operation. Restart of the reactor will not be a simple continuation of operation. It is indispensable to perform complete experimental program including measurements of critical parameters at different power levels for the core with fresh 80% enriched fuel. The aim of this document is to obtain working permission and its contents are in agreement with the procedure demanded by the Safety Committee of the Institute. It includes results of optimization and safety analysis for the initial reactor core. Since the permission for restart is not obtained, a separate RA reactor safety report is prepared in addition to the program for experimental operation. This report includes: detailed program for reactor experimental operation with 80% enriched fuel in the core at low  More>>

[Serbo-Croat] Od decembra 1976. godine redovno je korisceno 80% obogaceno gorivo u mesanoj resetki reaktorskog jezgra sa 2% obogacenim gorivom. Najvece izmene na reaktoru u odnosu na originalni projekat izvrsene su u nacinu rukovanja gorivom. Krajem marta 1979. godine obustavljen je rad reaktora usled naslaga na gorivnim elementima i loseg stanja teske vode. Naknadno je izdata zabrana za rad reaktora od strane Sanitarnog inspektora SR Srbije. Ponovno pustanje reaktora u rad nece biti jednostavan nastavak rada. Neophodno je da se izvede kompletan program merenja kriticnih parametara i drugih karakteristika reaktora RA na razlizitim snagama, i to sa pocetnom konfiguracijom jezgra formiranom iskljucivo od svezeg 80% obogacenog goriva. Sadrzaj ovog dokumenta koncipiran je u skladu sa procedurom koju zahteva Komitet za sigurnost Instituta da bi se dobila dozvola za rad. Shodno tome ovaj dokument sadrzi i rezultate oprimizacije i sigurnosnih analiza pocetne konfiguracije jezgra. Kako nije doslo do skidanja zabrane za rad, u okviru zahteva za dobijanje dozvole za probni rad pripremljen je poseban izvestaj o sigurnosti reaktora RA. Ovaj dolument sadrzi: Program probnog rada rada reaktora sa 80% obogacenim gorivom na malim snagama, i sadrzaj programa probnog rada reaktora RA sa 80% obogacenim gorivom na vecim snagama.}
