  26. AES-2006 – the targets reached • Thermal power has been increased up to 3200 MWand Efficiency factor (gross) of a power unit has reached 36.2%, due to: • elimination of excessive conservatism • improvement of steam turbine thermal circuit • improvement of steam parameters at the steam generator outlets and decrease of pressure losses in steam lines • Economic efficiency has been improved by means of: • optimization of passive and active safety systems used in AES-91 and AES-92 designs • unification of the main equipment; • decrease of materials consumption 26

  27. Negative effects of the world financial crisis • Industrial production shrinkage • Energy consumption recession • Grid restrictions and NPP generation reduction • Decreased profits and reduced investments in construction of new NPPs 27

  42. Systemic problems of the modern nuclear power • Low efficiency in beneficial use of mined natural uranium – less than 1% • Continuously growing volumes of SNF and RW 42

  43. Requirements to a nuclear power system (NPS) • Economical efficiency • Guaranteed safety • No limitations in regard to a raw materials base for а historically significant time span • SNF and RW management – the NP fuel cycle is to be organized in a way ensuring safe ultimate RW confinement • Energy production scale – the share in the national electricity market should be not less than 30% • Energy production structure is to ensure an opportunity to expand the markets

  44. A power unit of the 4th generation with a sodium-cooled fast reactor: • Complying with the requirements of large-scale nuclear power in areas of fuel utilization and minor actinides management • With improved technical, economic performance and safety features

  45. Requirements to VVER technology development aimed at its application in combination with breeder reactors within the closed NFC: • Fuel utilization (Breeding Ratio) • Efficiency coefficient • Investment paybackterms 45

  46. Target features of an innovative NPP unit based on the traditional VVER technology • Fuel utilization – possibility of operation with breeding ratio (BR)of ~ 0.8 – 0.9 and natural uranium consumption of 130 – 135 t/GW(e) per year • Thermodynamic efficiency- improvement of the efficiency coefficient by optimization of the steam generator design and by the maximum possible increase of steam parameters • Investment payback – shortening of the construction period down to 3.5 – 4 years due to the enlarged industrial modular fabrication
