Petrozavodsk Branch of JSC “AEM-technology” (a member of Atomenergomash, machine engineering division of Rosatom State Corporation, and Karelian Regional Branch of the Russian Engineering Union) has started semi knock down (SKD) assembly of reactor coolant pump sets (RCPS) which are to be delivered to Tianwan NPS (People’s Republic of China). The operating procedure was launched in front of Artur Parfenchikov, the Head of the Republic of Karelia, and representatives of Jiangsu Nuclear Power Corporation (JNPC, PRC).

Petrozavodskmash has started producing the first circumferential weld on the first RCPS housing for Tianwan NPS, Unit 7. The weld connects a flange and guide vanes welded thereto (an RCPS internal component) to a spherical blank forging. Upon completion of inspection operations and machining, the RCPS housing will go through further assembly operations – suction and discharge nozzles will be welded thereto.

An RCPS housing is an item of safety class I. At a nuclear power plant, this equipment provides coolant circulation within the primary circuit, and it is operated under a pressure of approximately 160 MPa and a temperature of 300°C. A delivery set per one unit includes four RCPS spherical housings.

“We are confident that through cooperation with our colleagues at the Petrozavodskmash plant, together we will ensure delivery of the high quality equipment within the terms established”, said Chen Qiang, a representative of JNPC.

“China is one of our key customers”, said Anatolii Smirnov, Acting Director of Petrozavodskmash. “What best describes our JNPC colleagues, is that they are result-oriented and aimed at fulfillment of the task assigned. A lot can be achieved through such partnership”, the Head of the Branch added.

Artur Parfenchikov and Anatolii Smirnov also discussed the issues of Petrozavodskmash development and support from the authorities of the Republic during the meeting. Particularly they raised the subject of tax benefits, investment and ecological programs, attracting and retaining of personnel at the plant.

“In response to tax benefits we are hoping to get further development of Petrozavodskmash which will result in additional tax payments, new vacancies and a salary rise for plant employees. Our mutual task today is personnel which shall be qualified, aimed at quality workmanship and strong results”, the Head of Karelia underlined.

At the end of the visit, Artur Parfenchikov presented Anatolii Smirnov with a Certificate of Merit by the Government of the Republic of Karelia for invaluable contribution of the Petrozavodskmash personnel to the social and economic development of the region.
