The Volgodonsk branch of AEM-Technologies, Atommash (part of Rosatom’s mechanical engineering division Atomenergomash) has manufactured the upper half of the reactor pressure vessel (RPV) for unit 3 of China’s Xudabao NPP in Liaoning Province, Atomenergomash said on 20 April. Atommash has completed the welding of circumferential seams on upper half of the RPV. The work lasted 25 days with continuous heating at 150-170 degrees Celsius in the area of welded joints. It took 4,700 kg of flux and 3,300 kg of wire to weld the circumferential seams. The component was then heated to 300 degrees and moved to a furnace for heat treatment to obtain the required mechanical properties of the metal. The process of heating and holding is done at a maximum temperature of 620 degrees for three days.

In line with plans to reduce its stockpile of depleted uranium hexafluoride (DUHF), a waste produce to uranium enrichment, enterprises of Russia’s Fuel Company TVEL (part of state nuclear corporation Rosatom) plans to build a new facility for the treatment of DUHF. The Central Design and Technological Institute (TSPI) and the Ural Electrochemical Plant (UECP) in Novouralsk, Sverdlovsk Region) had signed an agreement for the development a project to create a W-EHF facility in Novouralsk for defluorination of DUHF.
