Russia’s nuclear energy station operations arm Rosenergoatom introduced its strongest nuclear reactor thus far into industrial operation in February 2017, marking the newest evolution of its Water-Water Energetic Reactor (VVER) know-how. The reactor, Unit 6 of the Novovoronezh plant, holds many classes for future nuclear developments.

Rosenergoatom regards its Novovoronezh Nuclear Power Plant (NPP) as a dwelling historical past of nuclear energy, that includes six items (with extra beneath building) every an enchancment during the last. The plant has been the primary facility to launch and function all new VVER unit varieties for the final 50 years. “The Novovoronezh NPP is a sort of an open-air museum which permits tracing the entire life cycle of VVER reactors together with, operation, modernization, life extension, and decommissioning,” a spokesperson for Rosenergoatom informed POWER.

The plant is residence to the primary VVER-440 reactors to have their operational life prolonged through an annealing of the reactor vessel. The plant’s VVER-1000 reactor was modernized and upgraded to fulfill post-Fukushima security necessities, whereas decommissioning of Units 1, 2, and three is presently underway. “Novovoronezh NPP is a real coaching heart for the world nuclear business,” Rosenergoatom mentioned (Figure 1).

With the completion of Unit 6, Novovoronezh has continued its legacy of innovation. The newest operational iteration of Russia’s VVER know-how entered into industrial operation on February 27, 2017. The unit—additionally known as Unit 1 of Novovoronezh NPP-2—is seen by Rosenergoatom as a major step up from its predecessors.

“The new VVER-1200 energy unit relies on the newest developments and developments which all adjust to all post-Fukushima security necessities (for this reason the unit is taken into account to be Generation III+ superior reactor). At current that is essentially the most highly effective nuclear energy unit in Russia which enjoys three key benefits: excessive productiveness, sturdiness, and security,” in line with Rosenergoatom.

Increased Productivity

Novovoronezh NPP-2 is the primary nuclear energy plant of the brand new era AES-2006 design with VVER-1200 reactors. “The AES-2006 design is the standardized nuclear energy plant design that embodied the newest achievements of the Russian engineering. It relies on technical options of the AES-92 design,” in line with Atomenergoproekt, the final design and building contractor for Novovoronezh NPP-2.

The new unit’s capability is 20% better than the VVER-1000. According to Atomenergoproekt, the unit has a gross capability of 1,198 MW in comparison with the VVER-1000’s 1,000 MW. The unit is anticipated to provide 9.1 trillion kWh per 12 months in comparison with the VVER-1000’s 7.5 trillion kWh per 12 months.

In addition to elevated capability, the unit additionally improves the operational effectivity of earlier generations. The variety of personnel has been decreased by 30% to 40% (on a per MW foundation) because of automation, and the centralization of features and processes, Rosenergoatom reported.

Further, the design lifetime of the principle tools has been doubled, from 30 to 60 years, and different progressive design elements have been employed to chop prices. “For instance, the undertaking [employs] just one cooling tower as a substitute of two,” Rosenergoatom mentioned.

Unit 6 is the primary of the VVER-1200 era of reactor to be accomplished. “The expertise of the development and commissioning of the distinctive VVER-1200 energy unit on the Novovoronezh NPP has demonstrated that Rosatom State company and Rosenergoatom Concern have as soon as once more applied an progressive,…
