Chapter
The present study consists in the assessment of the dose rates potentially received by the workers involved in Hot Cells decontamination from a VVR-S type Nuclear Research Reactor under decommissioning. Two exposure scenarios were considered: the dosimetrist performing contamination scanning measurements (H*(10) inside of the Hot Cell prior deconta...
Article
The IFIN-HH VVR-S type Nuclear Research Reactor is currently in the decommissioning phase. During the operation period inside of the reactor building a workshop for mechanical processing of depleted uranium blocks was used. The purpose was containers manufacturing for biological shielding of Cs-137 and Co-60 sources. The dose rate and associated ri...
Article
The paper presents the risk assessment methodology for the critical group members (infants and adults) as a result of the radioactive effluents releasing, during VVR-S nuclear research reactor decommissioning process. The derived emission limits of the effluents were established using the transport model in the environment in order to comply with d...
Article
Full-text available
The radioactive inventory of the solid wastes resulted from decommissioning of the VVR-S research reactor from Bucharest, Romania, is assessed and compared to the estimated one. The main part of the inventory is concentrated in the reactor block and hot cells. The reactor block inventory was estimated by preliminary measurements and calculation bef...
Article
Present research analyzes, using non radioactive original concrete, the various mortar recipes in order to identify those that meet the proposed specification for fluidity and allow obtaining of the highest fill ratio for mortar.
Article
Our research involves developing two-stages crushing process for radioactive concrete that will produce recycled fine aggregate which is reused as mortar for filling containers. The tests were carried out on non-radioactive material (reference original concrete) because the radioactive concrete was not available at that time.
Article
The article presents the way in which recycled concrete aggregates' properties influence the features of the new concrete. There are discussed classic and innovative methods for radioactive concrete recycling, having as main purpose the increase of the radioactive waste volume. The authors perform an evaluation of the national level technique statu...
Conference Paper
During specific predecommissioning activities of WWR-S nuclear research reactor waste material are generated. At the same time we have waste materials generated in the operation period. These materials can either be reprocessed without harm or has to be disposed as waste. Unlike waste from conventional areas, waste material coming from nuclear faci...
Conference Paper
The aim of this program is the development of competence by training, acquiring, extending and maintaining competence, using fundamental or refreshment training courses. Progress and suited approach are established based on the list with tasks and subjects to be assimilated. According to 'graded approach to training' method the training process wil...
Article
The decommissioning of Research Nuclear Reactor VVR-S Magurele - Bucharest involves the removal of the radioactive and hazardous materials to permit the facility to be released without representing a further risk to human health and the environment [1-3]. A very important aspect of decommissioning is the analyze, justification and selection of the...
Technical Report
The superabsorbents obtained by gamma Co-60 processing with swelling capacity from 40g/g to 500g/g have been used in the: 1. land management; 2. toxic and hazardous materials in aqueous state management in emergencies situations; 3. deuterated and tritiated water accidentally spreading in various places. The hydrophilic absorbents obtained from rig...
Conference Paper
A decommissioning project was worked out concerning the nuclear facility research reactor WWR-S Magurele-Bucharest to remove the radioactive and hazardous materials and so to exclude any risk for human health and environment. The project involves the four phases named assessment, development, operations and closeout. There are two major parts to th...
