NPP unit No.3 was switched off. The reason was the defects of generator.
to the project algorithm, the unit was automatically unloaded to the capacity of
10%, and the unit capacity at 15:02 11.04.2015 was Npower=300MW,
April 2015, after the research, the damage of exciter No. 2 of the
turbine generator was defined (NPP electrical equipments, which do not relate
to SUNPP-3 nuclear safety issues).
SNRIU’s on-site Inspection
provides the continuous control on the NPP personal concerning nuclear and
radiation safety issues.
preliminary estimate the event was rated as the event without safety
significance – “below Scale/Level 0”
according to INES scale.
at the site of the South-Ukrainian NPP and neighboring area remains unchanged
at the value of 11,6 mR/h,
which is usual background radiation level for the NPP area.
