Bohunice might be in operation until 2046

The operator of power plant Bohunice V2 informed state authorities about the intention to operate both nuclear units for further three decades. 

Their original lifespan was designed for 30 years, i.e. until 2014 for the Unit III and 2015 for the Unit IV. If it is prolonged until 2046 as intended, they will generate electric power for 60 years.

Slovenske elektrarne are referring to the investment project of long-term operation of NPP V2 which started in 2010.

“The aim of this project is to prove that the NPP facilities will be able to fulfill their functions during the whole anticipated operation period while preserving all requirements of nuclear, radiation and technical security,” says the company communication submitted to the authorities. 

Modernization underway

The operator is convinced that owing to the executed refurbishments the operation could be prolonged.  Since 2002 a modernization program amounting to 500 million euro was implemented at both V2 units, and was completed in 2010 by power increase up to 505 MWe (gross) per unit.

 “The project was focused particularly on solving security problems, but also dealt with increase of the operation reliability of the facilities,” the company states. They added that all these tasks were designed and implemented with the prospect of prolonged lifespan until 2046. 

Bohunice NPP is located near the city of Trnava. Electricity is generated in two units with VVER 440/V-213 pressurized water reactors, which were commissioned in 1984 and 1985 respectively.

The V2 power plant changed to combined generation of electricity and heat after building up the centralized heat supply system from Bohunice NPP to Trnava in 1987. Until 1996 more than 300 facility modifications were made.

On October 17th and 18th an extensive nuclear safety drill was executed in the premises and neighboring districts. (See older post)
