Wednesday, 1.3.06 the reactor was shut down after the regular end of the 5th cycle. The 6th cycle is scheduled for start-up on 24.3.06. The break between the 2 cycles will be used for routine tests and for installation of new neutron guide systems.
Successful Start of Routine Operation at FRM II
The reactor has been shut down on Sunday, 22.01. 2006 due to a warnig signal in the secondary cooling system, where the cause can not be checked during power operation. This procedure is in accordance with the operating guidelines (BHB) for the FRM-II. The directorate of the research neutron source Heinz Maier-Leibnitz.
Das Neutronen-Röntgen-Konstrast-Reflektometer N-REX+ wurde am 24.11.2005 eingeweiht. The neutron / X-ray contrast reflectometer N-REX+ was inaugurated on 2005-11-24.
On July,12th the FRM-II was started up, as scheduled, to the nominal power of 20MW. Thus the third power cycle of FRM-II is running. With a short, planned break in early August, the end-of-cycle is scheduled for September 6th 2005.
After successful operation of 48 days the reactor was shut down on 24.6.2005 at 10:46 due to a perturbation on a sensor monitoring the flux of the cooling water. The cooling itself was not disturbed. This shut down ends the second cycle. The remaining 4 days of operation will be used later. The planed maintenance goes on as scheduled. The third...
In the evening of 14. June 2005 FRM-II had to shutdown due to a current interruption in the electricity network in the Garching region. This current interruption was caused by a thunderstorm. Whereas the current came back after a few seconds, restarting of FRM-II had to wait some 40 hours due to the Xenon build up in the core. On 16. June FRM-II...
