Radioactive Waste Characterization

Provision of RAW characterization services is primarily related, but not limited to the RAW treated and conditioned on Jaslovské Bohunice site. 

Provided radioactive waste characterization services include:

1. DESIGN AND IMPLEMENTATION OF RAW CHARACTERIZATION SYSTEM

• Elaboration of RAW characterization procedure
• Setting the reference radionuclides necessary for the determination of the activity of the radionuclides dificult to measure.  
• Design of software and hardware laboratory equipment necessary for RAW characterization

Design and elaboration of methodologies for the determination of the radiochemical, physical, chemical,and mechanical properties of RAW in compliance with acceptance criteria

2. DESTRUCTIVE ANALYSES OF RAW SAMPLES

Radiochemical analysis

• gammaspectrometry
• alphaspectrometry
• liquid scintillation spectrophotometry
• total alpha and beta activity measurement
  

Chemical analysis

• pH
• specific conductivity
• concentration of cations by absorption spectrophotometry
• concentration of anions by UV/VIS spectrophotometry
• concentration of boric acid by potentiometric titration
• concentration of tensides by extraction
• chemical and biological oxygen consumption
• water hardness

Physical and chemical analysis

• thermal properties of substances by differential thermal analysis
• RAW leachability index
• viscosity of solutions
• basic physical properties of bitumen (flash point, softening point, penetration, water content)
• content of soluble and insoluble substances in solutions
• sorptive capacity of ion exchangers

Mechanical properties

• determination of compression strength of cement products
• determination of discharge speed of cement paste

3. NON-DESTRUCTIVE INSPECTION OF RAW

• determination of gamma activity of RAW in 200 l barrels (gamma scanner)
• determination of plutonium content of RAW in 200 l barrels using the method of measuring passive neutrons (alpha scanner)
