“When building a machine as large and as complex as ITER, difficulties and setbacks do not come as surprises - they are an integral part of manufacturing, assembling and installing first-of-a-kind components,” the ITER Organisation said recently.

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.

The COVID-19 pandemic has created an unprecedented demand for personal protective equipment (PPE), part of which must be sterile, i.e. exempt from any microorganism such as bacteria or moulds that can compromise the wearer’s or the patient's safety. It was realised that whilst irradiation is routinely used to sterilise medical products it might also be possible to use the technology to increase the available supply of PPE, writes Paul Wynne, chairman of the International Irradiation Association.
