Experience with V-1 nuclear power plant operation

The physical and power start-ups of the V-1 nuclear power plant are described. The physical start-up reached the aim preset in the schedule and confirmed the designed values. The power start-up confirmed that the primary coolant circuit had higher operating reliability than the secondary circuit. A list is given of shortcomings and failures of the secondary coolant circuit. The chemical regime of the primary circuit was stable, without significant deviations. The chemical regime of the secondary circuit was burdened with a number of failures. In spite of the said problems, the V-1 plant operated reliably. (J.B.)
