[en] Automatic translation: Also in the 1st quarter of 1970 there was a high availability of the Aimed at plant. Relative to generator operating hours achieved the time availability 85%. On January 19, 1970, there was a planned short shutdown break with a stick drop test is initiated in which the reactivity equivalent the shutdown rods was determined. Immediately afterwards the system was started up again and a hot one Approved start-up. In the afternoon - after reaching a quasi steady state - The system then became final after a rapid shutdown attempt corresponding to the KFA reactor accident for the intended Pause taken out of service. The most important work in the short shutdown pause was: Installation of a device in the frequency converter which allows replace brushes under load; Revision of Valves and replacement of blown coils of solenoid valves in protective container; Work on the loading system and cleaning the condenser. The work was finished on January 22nd, 1970 as planned. The start-up of the reactor was made possible by work on the charging system delayed until January 25, 1970. By concatenation several malfunctions had about 350 bullets in the The funnel accumulated below the debris separator finally with a pneumatic suction device removed from the funnel. When the reactor was started up on January 25, 1970, a new one was created Approved start-up procedures to further shorten the start-up process. The repair work on the debris separator of the charging system were at reactor operation from late January to early March 1970 continued.
