The Zittau teaching and research reactor ( ZLFR ) was a teaching and research reactor , which was operated from 1979 to 2005 at the engineering college Zittau as well as at the later Zittau / Görlitz college . The reactor with an output of ten watts was mainly used for training and teaching purposes, but it was also used in research projects. He lost his operating license as a result of the unification treaty between the Federal Republic of Germany and the GDR .

history

The Zittau teaching and research reactor was designed as a training reactor for the operating personnel of Soviet pressurized water reactors of the VVER type. Construction of the nuclear reactor began in 1976, and it reached its first criticality on May 25, 1979. Later it was used to train students in the fields of nuclear and radiation technology. Due to the transitional regulation for nuclear facilities of the former GDR in the unification agreement, the teaching and research reactor lost its operating license on June 30, 2005. The reactor was dismantled between July 1, 2005 and March 3, 2006 and all radioactive material was removed. The decommissioned teaching and research reactor is now used as a "nuclear cabinet" for illustrative purposes. The centerpiece of the cabinet, which was opened on January 15, 2008, is a reactor simulator, which consists of preserved components of the ZLFR and a PC with which the operating and accident behavior of the reactor can be simulated.

construction

The Zittau teaching and research reactor was a tank-type zero-power reactor . The reactor vessel had a cylindrical shape with a height of 1.5 meters and a diameter of 1.4 meters. The biological shielding consisted of an outer wall made of concrete with a thickness between 30 cm and 100 cm, the area between the reactor container and the outer wall being filled with water.

Uranium enriched to 36 percent was used as nuclear fuel , with 22 single and 24 triple fuel elements being used. The critical mass was around 3700 grams of uranium. The reactor was moderated with light water and had a maximum thermal output of ten watts. The maximum thermal neutron flux was 2 × 10 ⁸  n / cm ²  s.
