Hot Cells Facility, (Objekt Vroča Celica OVC), is intended for characterisation, sorting and treatment of radioactive materials.The OVC comprises three rooms:

 

  1. Manipulation room
  2. Central preparatory room
  3. Radiological measurements room

 

Room B room comprises two hot cells VC1 and VC2, and eight digestors. Between the hot cells there is a depository for solid radioactive materials with 32 positions (dimensions Φ 100 mm x 100-250 mm). VC1 and digestors (D1…D4) are intended to be used for work with radioactive sources from the manipulation room A. VC2 presently serves as a radioactive material storage. Otherwise it can be upgraded for work with radioactive sources from the radiological measurements room C. The remaining four digestors (D5...D8), located within the radiological measurements room C, are used for various measurements. All rooms are under continuous radiological surveillance.

 

Hot cells and digestors usage and equipment available

 

  • VC1 is connected with the TRIGA reactor via pneumatic system for transferring irradiated samples. It is equipped with a device for the opening of irradiation containers and master-slave manipulators for handling radioactive sources. It is designed to work with activities of up to 1000 Ci (Co-60).
  • VC2 is intended for storing radioactive sources with activities of up to 1000 Ci (Co-60).
  • D1 and D2 are equipped with manipulators and intended to manipulate sources with activities of up to 10 Ci (Co-60).
  • D3 and D4 are intended to manipulate sources with activities of up to 0.1 Ci (Co-60).
  • D5…D8 are intended for carrying out radiological measurements.

 

Equipment available at OVC

 

  • Crane with load capacity of 3.5 tons
  • Ultrasonic decontamination bath (dimensions 500 x 400 x 400 mm)
  • Hidraulic press for compacting materials in standard 210 L casks
  • Portable booth made from PVC-film strengthened poliester (dimensions 4 x 2.5 x 2.5 m)
  • Mobile vacuum cleaner with HEPA filtration
