ASE Group of companies is established as part of the Engineering Division of Rosatom State Corporation by consolidating the industry’s leading companies, such as JSC ASE Engineering company (the former JSC NIAEP, Nizhny Novgorod), JSC Atomenergoproekt (Moscow), JSC ATOMPROEKT (St-Petersburg), JSC Atomstroyexport (Moscow).

With their historical background, all design institutes of the nuclear industry have descended from the All-Union State Design Institute “Teploelektroproekt” that was founded in Moscow in 1924 to implement the ambitious GOELRO plan.

Initially, the “Teploelektroproekt” was engaged in construction of power plants and heat generation facilities alone at the scale of the whole Soviet Union. As NPP designing was singled out as a separate project in 1958 only, Teploelektroproekt was appointed by the special governmental decree as an NPP general designer.


The succeeding party to the legendary Teploelektroproekt is the Moscow Atomenergoproekt, the oldest design institute of the industry. It is recognized as a leader in the area of nuclear island and APCS designing, engineering survey, probabilistic safety analysis.

Over the years of work, the company’s experts have designed the majority of NPPs on the territory of Russia, Eastern Europe and CIS. In particular, the organization is involved in designing of all power units of the Novovoronezh NPP which is the oldest commercial nuclear facility in Russia including the first and the latest Gen 3+ power units of the Novovoronezh NPP-2.

Currently, the NPPs designed by JSC Atomenergoproekt account for 12% of the cumulative power generated by all NPPs throughout Russia. Atomenergoproekt’s developments are recognized outside this country owing to the company’s participating as the General Designer in construction of Kozloduy NPP (Bulgaria), Temelin NPP (Czechia), Kudankulam NPP (India), Akkuyu NPP (Turkey), Zaporozhe NPP (Ukraine) In particular, JSC Atomenergoproekt experts have developed a unique Bushehr NPP project in Iran that has integrated for the first time ever the Russian technological equipment into the German-designed civil engineering structures.


Petersburg designers of nuclear facilities are represented by JSC ATOMPROEKT. The company was founded on July the 1st, 2013 by merging the competences of St-Petersburg veteran nuclear designers, such as JSC Lead Research Institute VNIPIET and JSC St-Petersburg Atomenergoproekt. The St-Petersburg experts’ designs include the world’s first NPP in Obninsk, all commercial nuclear facilities in Russia and over 20 research nuclear reactors worldwide, design documentation for 17 NPPs. JSC ATOMPROEKT engineers designed the entombment project for the Chernobyl NPP Unit 4, that was constructed within the shortest ever time.

Now, VVER-1000 designed by JSC ATOMPROEKT is the basis for construction of the Tianwan NPP-2 project in China, VVER-1200 design is used in construction of the Leningrad NPP-2 and the Belarus NPP. In October 2014, the St-Petersburg institute signed a contract for development of the complete package of Hanhikivi-1 NPP design documentation to reiterate its status of the General Designer. The works are being executed for the Paks-2 NPP in Hungary. The institute carries out complex designing of nuclear facilities, R&D works, development of the most advanced nuclear power technologies. JSC ATOMPROEKT participates in the “Breakthrough” project, i.e. the complex of closed nuclear fuel cycle technologies applied at fast reactors.

Joint-Stock Company ASE Engineering Company

ASE Engineering Company (the former JSC NIAEP) originated from the Nizhny Novgorod (Gorky) Division of Teploelektroproekt and was founded in 1951. Year 1968 saw the institute proceed with NPP designing. The first Armenian NPP project turned out to be a genuine scientific breakthrough. As part of the project, the designers developed a seismic-resistant reactor plant that demonstrated its absolute safety by being capable to withstand the severe Spitak earthquake.

The Nizhny Novgorod Atomenergoproekt has marked a place for itself in the recent history books, too. The company has to its credit the first start-ups of new post-Soviet power units, such as: Rostov NPP units 1 and 2 (started in 2001 and 2010, respectively), Kalinin NPP units 3 and 4 (started in 2005 and 2012, respectively). These projects opened the way for the Russian nuclear renaissance. Currently, JSC ASE EC is the lead organization of ASE Group of companies.


JSC Atomstroyexport is the leading construction company of the nuclear industry. It was founded in 1998 by merging of 2 major Russian EPC- contractors engaged in construction of NPPs abroad, Namely JSC Atomenergoexport and VPO Zarubezhatomenergostroy. Atomeneroexport and Zarubezhatomenergostroy experts were engaged in construction and commissioning of 29 NPP power units in 7 countries.

In 1998, Atomstroyexport became the Russian leading player at the global NPP construction market to undertake implementing of the earlier concluded intergovernmental agreements and simultaneously initiate the works given new facts of life. JSC Atomstroyexport commenced its work when the national nuclear industry was in a standstill, but eventually, this were just foreign projects that propped up the Russian nuclear power businesses and helped them maintain and boost their potential, get ready to implement the large-scale programme for the national nuclear power advancement.

ASE Group of Companies

Currently, ASE Group of company that took its final shape by 2015 is one of the leaders at the global nuclear engineering market. ASE accounts for 31% of the global construction market. The Group of Companies’ representative offices, branches and front offices are operating in 15 countries, with the total manpower exceeding 15 thousand persons and

foreign projects accounting for over 80% of the portfolio. The Group of Companies’ worldwide geography covers Belarus, Iran, India, China, Turkey, Czechia, Bangladesh, Egypt, Hungary, Finland. The major Russian projects of ASE Group of Companies include Novovoronezh NPP-2, Rostov NPP, Kursk NPP-2, Leningrad NPP-2.

The main areas of ASE Group of Companies’ business activities are such as:

  • – NPP designing;
  • – arrangement of civil and erection works;
  • – equipment and materials procurement management;
  • – Arrangement of pre-commissioning, commissioning works, NPP engineering supervision.

ASE Group of Companies’ competences encompass as well construction of RAW and SNF management facilities. The Engineering Division of Rosatom State Corporation is rated among the top 10 players holding this market share. Moreover, ASE Group of Companies provides the full range of EPC, EPC(m) and PMC services for any complex engineering projects and is engaged in construction of heat power engineering facilities.

The key competitive advantage of ASE Group of Companies applies the innovation project management system based on the Multi-D technology including both IT-tools and business processes. Application of this technology allows optimization of “deadline-budget-quality” parameters during construction of capital construction facilities.
