Long Term Operation of Bohunice Nuclear Power Plant

Units 3 and 4 of Bohunice NPP were put in operation in 1984 and 1985. They are of a standard WWER-440 design, type V-213. Slovakia is a member of the IAEA, EU, OECD and other international organizations. Country's National Council approved the Act 541/2004 on peaceful use of nuclear energy (atomic act) on 9 September 2004. LTO requirements are defined in Regulation No.33/2012 on PSR issued by UJD (see Appendix I). The regulation is in legal force since 1 March 2012. The overall objective of plant long term operation (LTO) programme was to demonstrate that the relevant systems, structures and components (SSCs) would perform their safety functions throughout the entire LTO period. More recently a comprehensive robust plant programme¹ was introduced: this programme is aimed at replacement or modification of those structures and components (SCs) which have not been replaced or modified during the plant first modernization programme and power uprates.
