A team of about 50 GNS employees was involved with preparations for the ASME audit in the 18 months leading up to it.
GNS managing director Jens Schröder said the company’s German and European customers have adopted a quality management system that complies with ISO standards, but other international customers increasingly rely on rules and regulations that are based on US standards.
He said the ASME authorisation, known as N3, will allow GNS to further explore other international markets where this type of certified compliance means it can meet the product requirements of new customers.
GNS is a supplier of casks for spent fuel, intermediate-level radioactive waste and high-level radioactive waste. The company, whose headquarters are in Essen, also offers services for the management and disposal of spent fuel and all types of radioactive waste.
