Cells Facility, (Objekt Vroča Celica OVC), is intended for
characterisation, sorting and treatment of radioactive materials.The
OVC comprises three rooms:
- Manipulation room
- Central preparatory room
- Radiological measurements
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.
