Rotary Rack
Rotary rack (RR) (Figure 1) is located inside a graphite reflector assembly around the reactor core. RR contains 40 positions that can accommodate 79 samples. This rack can be rotated manually (using a dial) or using an electric motor with a speed of 1 rotation per minute.
The sample to be irradiated must be placed in a sample container (plastic vial). The container is measured and placed in an irradiation container (polyethylene or aluminium irradiation container). Figure 2 shows both the sample container and the polyethylene irradiation container used.
Special hook rods used to insert and remove samples for RR (Figure 3).
The main uses of rotary rack are for the formation of medium and long-lived radioisotopes. These radioisotopes are used for neutron activation analysis, diagnosis and therapy, non-destructive testing, and so on.
