6. Isotope Production Reactor Heat produced in reactor core is removed by cooling fluids and carried to steam generator (in power reactor) Cd or B, which absorb neutrons. They help to regulate the flux of neutrons. Inserted to slow down the neutrons to make them more easily captured. Samples are stable isotope for radionuclide production from neutron capture reaction. U-235 also can be the target of (n,f) reaction for radionuclide production. *water or D2O can be coolant and moderator at the same time.

33. Conclusion -Product atom has same charge -Low specific activity -Short half-life -expensive Disadvantage -Less expensive -Product atom has different charge -High specific activity Advantage -Target bombarded with neutron. -Target bombarded with charged particles (proton, deuteron). Definition of the method Nuclear reactor Accelerators
