Petrozavodsk Branch of JSC “AEM-Technology” (a part of machine-building division of Rosatom State Corporation – Atomenergomash and Karelian Regional Wing of the Russian Engineering Union) has conducted the first complete shipment of equipment for Akkuyu NPP (Turkey), Power Unit 1. A set of reactor coolant pump sets (RCPS) manufactured at Petrozavodskmash was shipped in compliance with all anti-epidemic measures with involvement of limited number of participants.

The Director General of AEM-technology – Igor Kotov pointed out that despite all the difficulties Petrozavodskmash managed to ensure shipping of RCPS housings set – complicated nuclear equipment of safety class 1 – within the specified dates.

“In general this year the company provides for shipment of main equipment sets for three power units. This is a sort of a record. But the most important thing for us are not records, but the fact that we are actually switching to serial production and the largest share of this Russian produce is intended for export. A meaningful contribution towards these achievements has been made by Petrozavodskmash – one of the main manufacturing sites of nuclear machine-building nowadays”, – he said.

A shipment set of RCPS housings for a power unit consists of four spherical housings with fastening components – spacers. Weight of one casing is more than 31 tons with height of 3.5 m and width more than 3 m. Together with a spacer the weight approaches 50 tons. From Petrozavodsk the items are delivered by automobile transport to the Bronka terminal of the Sea Port of Saint-Petersburg where it will be loaded on board a ship.

In the course of manufacture RCPS housings are subjected to different types of inspections including X-ray examination. Also there is an ensemble of tests, the most important being the final hydraulic test by excessive pressure (24.5 MPa). After obtaining favourable conclusions for results of all inspections the equipment is prepared for shipment: it is painted and preserved.

RCP housings are safety class 1 items. At a nuclear plant a reactor coolant pump ensures coolant circulation in the primary circuit and operates under pressure of 160 atmospheres at temperature of 300℃.

Akkuyu NPP is the first NPP in Turkey being constructed on the south cost of the country, in Mersin province. The plant is constructed according to an improved NPP design with GenIII+ VVER-1200 power units with enhanced safety and improved technical and economic features. JSC "Atomenergomash" is the single-source manufacturer of equipment for the reactor system and the turbine island for all four units of the plant.
