Difference between Power Reactors
and Research Reactors Research reactors are nuclear reactors that serve primarily t Th l as a neutron source. They are also called non‐power reactors, in called non power reactors, in contrast to power reactors that are used for electricity production, heat generation or maritime propulsion generation, or maritime propulsion.

Irradiations are classified into three main types A) Long Term Irradiations B) Medium Term Irradiations ) C) Short Term Irradiaons C) Short Term Irradiaons
SLIDE 36
Long Term Irradiations Long Term Irradiations
The Samples are irradiated for l several years Examples are Cobalt and Irridium Examples are Cobalt and Irridium
SLIDE 37
Medium Term Irradiations Medium Term Irradiations
In Dhruva these are mainly In Dhruva these are mainly produced for Medical diagnosis produced for Medical diagnosis and Treatment and mostly irradiated for three to four days Examples are Molybdenum based l hi h h bl samples which have reasonably short life short life
