TRIGA-Mark-III reactor

• Built in 1966

• There are hot-cell laboratories and various neutron irradiation facilities.

• Reactor power 250 kW maximum

• Total flux is 4*10¹² cm^-2s^-1 (central channel).

• Several in-core and ex-core irradiation channels

• Maximum uninterrupted irradiation time is 16h.

Types of irradiation

In-core (fast & thermal neutrons)

• Flux 1-4*10¹² cm^-2s^-1
• Hardness factor ~0.9
• Sample size < 20*7*1 cm³

Dry chamber (thermal neutrons, regenerated fast neutrons)

• Flux <5*10⁸ cm^-2s^-1
• Bigger samples possible

In-core off mode (gamma)

• Secondary radiation of the core when reactor is off
• Monitored with RADFETS
• 50 Rad/s max, levels off at 20 Rad/s

The preferred method is to send samples for irradiation at the JSI TRIGA-Mark-III reactor. Users are welcome to come with their samples to JSI, but will need to cover their travel costs.
