Triga Mark II type nuclear research reactors designed by General Atomics company and TRIGA acronym comes from "Training Research Isotope Production General Atomic". Mark II is a TRIGA version which has constant core and located above the land surface.
ITU Triga Mark II Reactor, started to serve at 11th March 1979 as 54th Triga reactor at around the World. Past 35 years electronic technology developed very rapidly but Triga control and measurement systems stayed “old fashioned”.
“reTriga” project targeted to “redesign”;
1. Power measurement systems (gamma and neutron detection)
2. Thermal measurement (fuel and water temperatures)
3. Reactor control rods electromechanic system,
4. Neutron source electromechanic automation
5. Reactor pool cooling and water purification systems
6. Pneumatic transfer (Rabbit) system
7. Central beaming transfer system
8. Radiation area monitoring remote data collection system
9. Underwater LED ligthing system
10. Digital controlled High Voltage (500-1000 VDC) Power supplys for nuclear detectors
11. NAS backed up SQL database system for operation data collection and storage
12. State of Art reactor control console
All systems listed above totally redesigned and produced by Turkish engineers and academicians.
