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...
