BD Delegation Visits Russia’s NPP

A   Bangladesh   delegation   comprising   the   Ambassador   to   Russia   Dr.   S.   M.   Saiful   Hoque,
representatives of Ministry of Science and Technology and other concerned departments visited
the Novovoronezh nuclear power plant in Russia. The  Novovoronezh NPP is  the  reference
project for the under construction Rooppur NPP in Bangladesh.
The   delegation,   accompanied   by   Vladimir   Zarubaev,  Deputy   Chief   Engineer   for   Inspection
Atomenergoproekt went round the different facilities of power units 6 and 7 of the Novovoronezh
NPP. The delegation was explained the operational aspects and advantages of new generation
VVER-1200 reactors being used at those units.
They   also   visited   the   complex   gas-insulated   switchgear   of   500   kV   (GIS–500),   protected
emergency response control post (FP), and the block power unit control post. They were shown
condensate purification plant (CPP) and the fresh fuel storage facilities, cooling tower of power
unit- 6 as well. The cooling tower is a vital 172 m high hydraulic structure, which serves for
cooling circulating water in the second circuit and thereby cooling of the reactor itself.
The  delegation   went   round the   under  construction  turbine   hall  and  reactor   compartment  of
power unit No.7, as well as the laboratory for environmental monitoring and the training center.
Bangladesh Ambassador expressed his satisfaction with the high standard of safety maintained
at the nuclear power plant.
Power units No.6   and  No.7   of   the  Novovoronezh   NPP  are a typical design  of   the   new  3+
generation Russian NPPs with improved technical and economic figures. They are constructed
according to the “NPP-2006” design and equipped with a VVER-1200 reactor. The design is
based on half a century’s experience of secure and accident-free operation of NPPs with VVER
reactors. The current design takes into account the implementation of requirements of Russian
scientific and technical documentation and IAEA recommendations.
The main feature of the innovative power units is the use of additional passive safety systems
combined with traditional active systems. The design of the units provides protection against
earthquakes,   tsunamis,   hurricanes,   and   plane   crashes.   The   reactor   hall   has   a   double
containment; the core catcher is installed under the reactor vessel, the power unit is equipped
with a residual heat removal system.
The power unit- 6 of Novovoronezh NPP is at the physical start up stage at the moment and will
be connected to the grid very shortly. This will be the first ever 3+ generation NPP of the world
to generate electricity on commercial basis.
