A PART OF THE RESIDUAL HEAT REMOVAL SYSTEM - THE AUXILIARY CONDENSER - TEMPORARILY NOT AVAILABLE

At this occasion the auxiliary condenser after a few seconds was deactivated. An erroneous temperature measurement terminated its operation. The operator rectified the error within a couple of minutes. The error was introduced by design work during modifications.
