Mochovce Nuclear Power Plant
Spálovský, Inc., a major producer of low voltage switchgears in the Czech Republic won in 2010 the contract to
supply LW switchboards for three projects related to the
extension of the nuclear power plant in Mochovce, Slovakia.
The project regards the construction of two new reactors,
unit 3 & 4, originally commenced for operation in 2012
and 2013.
The Mochovce units 3 & 4 are designed and built according
to the proven and well consolidated pressurized water reactor technology and includes the latest technology developments and safety improvements. With reference to a general
project update and to the accident af Japan’s Fukushima
nuclear power plant the opening has been delayed until
2014 for unit 3 and 2015 for unit 4 due to increased safety
standards. Consequently, the plant will when in operation
comply with and even exceed current international safety
requirements and thus be comparable to nuclear power
reactors under construction in the European Union.
When in full operation, the Mochovce site consists of four
nuclear reactors with a total installed capacity at 12,000
GWh equal to around 45 % of Slovakia’s electricity consumption.
The Mochovce project is part of the one of the largest investments ever in the power engineering sector of Slovakia. The
completion is estimated at 3.8 billion EUR.
Spálovský
Spálovský, the Czech partner of CUBIC, won the project
due the ability and reliability of the company in companion
with the quality and certified operating system of CUBIC.
Spálovský, formed in 1990, has its core competences in
the production of LV switchboards up to 1000V/6300A and
steel sheet switch boxes. In conjunction with a full customer
service and integrated management systems according to
ISO 9001, ISO 14001 and OHSAS 18001 the company is
today among the top switchboard producers in the Czech
Republic.
The Switchboards
At Mochovce, Spálovský has supplied various 400 V / 50
Hz Main and Auxiliary switchboards ranging from 3002250 A and in modular sizes from 8x11x3 to 36x11x3.
The swithboard are designed for a diesel generation station
6
and chilled water station respectively. All switchboards are
seismic resistant and constructed with the Multi Drawer
withdrawable system. 90 % of the components applied
are Schneider.
